    BACKGROUND: This cross-sectional study aimed to investigate the relationship of the ACTN3 genotype with thigh muscle volume and physical performance in older adults with sarcopenia or pre-sarcopenia. METHODS: Data from 64 older Japanese adults (mean age 74.4 ± 6.9 years, women 71.9%) with sarcopenia or pre-sarcopenia were analyzed. Sarcopenia and pre-sarcopenia were defined using the Asian Working Group for Sarcopenia. We collected oral mucosa samples to determine the ACTN3 genotype. Thigh muscle volumes were measured using magnetic resonance imaging. Physical performance was assessed using the usual and maximum gait speed, timed up and go test, and five-repetition sit-to-stand test. Muscle strength was assessed using grip strength. RESULT: The ACTN3 genotype proportions were 20.3% for RR, 51.6% for RX, and 28.1% for XX. Participants with the RR genotype showed greater thigh muscle volume/ht2 compared to those with the RX and XX ACTN3 genotypes (p < 0.05). The multiple linear regression analysis revealed that RX (p < 0.01) and XX (p < 0.01) ACTN3 genotypes, compared to RR, were associated with lower thigh muscle volume/ht2 and with age, sex (reference; men), weight and maximum walking speed. There was no significant difference between physical performance and muscle strength between the ACTN3 genotypes. CONCLUSION: The ACTN3 genotype of the X allele was associated with decreased thigh muscle volume compared to the ACTN3 genotype of RR in older adults with sarcopenia or pre-sarcopenia.

    Regular exercise may be associated with better self-rated health and sleep status. However, this correlation among various age groups, such as young, middle-aged, and older people, as well as during the COVID-19 pandemic, has not been examined. This study examined the correlation between regular exercise and self-rated health and sleep quality among adults in Japan during the COVID-19 pandemic. Data were collected using an online survey conducted between February 26 and 27, 2021. A total of 1410 adults in Japan (age range, 20-86 years) completed the online survey. Regular exercise was divided into: (1) more than 30 min of moderate exercise a day, (2) more than 2 days per week, and (3) continuous for 1 year or longer. Self-rated health and sleep quality were assessed using the Likert scale. After adjusting for multiple confounders, regular exercise was correlated with decreased poor self-rated health and poor sleep quality in middle-aged adults; however, no significant correlation was observed among young and older adults. The promotion of regular exercise among middle-aged people during the COVID-19 pandemic may contribute to better self-rated health and sleep quality status.

    The COVID-19 pandemic has caused an abrupt change in lifestyle for many people with restrictions, often leading to a decrease in physical activity (PA), and thus contributing to a negative perception of health status. The purpose of this study was to examine the effects of the COVID-19 epidemic on physical activity and perceived physical fitness in Japanese adults aged 40 to 69 years. Data were collected from an online survey conducted between October 19 and 28, 2020. The analytic sample consisted of 1989 Japanese adults (mean age, 50.1 ± 6.9 years; women, 38.9%) who were aged between 40 and 69 years and completed the online survey. Overall, the PA time per week decreased by 32.4% between October 2019 and April 2020. A decrease in PA time was recorded in October 2020; however, a decline of 15.5% was observed. Compared to individuals who did not perceive a decline in physical fitness, individuals who perceived declining physical fitness during the COVID-19 state of emergency demonstrated a greater decrease in PA time in April 2020 (-50.5%), and this trend continued into October 2020 (-25.0%). These findings may indicate that Japanese adults aged 40 to 69 years who perceived declining physical fitness experienced a greater decrease in physical activity.

    AIM: Perceived health status, including physical and cognitive fitness, will be negatively associated with future health conditions among old-old adults. The coronavirus disease 2019 (COVID-19) pandemic has caused sudden changes in lifestyle. Thus, this study examined the associations of participation in an exercise class before the COVID-19 pandemic and the exercise habits and disruption to the rhythms of daily life during the COVID-19 state of emergency with perceived declining physical and cognitive fitness among community-dwelling old-old adults. METHODS: In July 2020, we carried out a mail survey of community-dwelling old-old adults aged between 77 and 99 years in Bibai, Hokkaido, Japan, to determine their perceived declining physical and cognitive fitness during the COVID-19 state of emergency. RESULTS: Of the 774 responders, 339 (43.8%) participants reported a decline in physical fitness, whereas 259 (33.5%) perceived declining cognitive fitness during the COVID-19 state of emergency. In a multivariate logistic regression model adjusted for potential confounders, exercise habits during the COVID-19 state of emergency were significantly associated with a lower perception of declining physical fitness. Disruption to the rhythms of daily life during the COVID-19 state of emergency was significantly associated with a higher perception of declining physical and cognitive fitness. CONCLUSIONS: Approximately half and more than one-third of community-dwelling old-old adults perceived declining physical and cognitive fitness, respectively, during the COVID-19 state of emergency. During this period, exercise habits were positively correlated with perceived health status among old-old adults, whereas disruption to the rhythms of daily life was negatively correlated.

    BACKGROUND: Hearing impairment (HI) is associated with dementia. However, the cognitive screening tasks effective in older community dwellers presenting with HI are unclear. METHODS: We retrospectively and cross-sectionally investigated the associations between HI and cognitive function assessed with screening tasks using data from two healthcare check-up programs for community dwellers ≥65 years old in 2018. We examined demographics, risk factors, cognitive function, hearing condition, lifestyles, and self-care levels. Cognitive function was assessed using the clock drawing task and the delayed three words recall task. Hearing condition was assessed using questionnaires on the use of hearing aids and HI during conversation situations. Multivariate analysis was used to identify independent associations between HI and cognitive assessment tasks. RESULTS: We analyzed 1602 eligible participants (61.9% women; 74.3 ± 6.5 years old). Hearing aid users (n = 90) were older (80 vs. 73 years, respectively; p < 0.001) and less likely to draw the clock correctly (71.1% vs. 80.1% years, respectively; p = 0.044) than non-hearing aid users. Multivariate logistic regression analysis showed that HI was associated with inability to draw the clock correctly (odds ratio 1.60, 95% confidence interval 1.12-2.26; p = 0.011), independent of age, living alone, memory impairment, and impaired self-care levels. CONCLUSION: Hearing impairment is independently associated with cognitive decline assessed by the clock drawing task. The clock drawing task may be useful for identifying an increased risk of dementia in older subjects presenting with HI.

    Health literacy is important for promoting and maintaining good health in old-old adults. It may influence the implementation of exercise in the coronavirus disease epidemic. The present cross-sectional study investigated the association of each dimension of health literacy with the implementation of exercise during the declaration of a state of emergency due to coronavirus disease in community-dwelling old-old adults. We collected data from 483 community-dwelling old-old adults (52.8% women) aged between 77 and 99 years who participated in a mail survey. Participants were divided into exercise or nonexercise groups based on the implementation of exercise during the declaration of a state of emergency. Health literacy was assessed using a 14-item health literacy scale. There were 327 (67.7%) participants in the exercise group and 156 (32.3%) in the nonexercise group. A significantly higher score of health literacy was observed in the exercise group than in the nonexercise group (communicative health literacy score = 14.0 ± 3.6 vs. 12.7 ± 3.8, p = 0.001). In a multivariate logistic regression model adjusted for potential confounders, high communicative health literacy scores were significantly associated with the implementation of exercise during the declaration of a state of emergency (odds ratio = 1.88, 95% confidence interval = 1.20-2.93). Approximately two-thirds of community-dwelling old-old adults implement exercise during the declaration of a state of emergency. High communicative health literacy was associated with the implementation of exercise during this period.

    During the last three decades, Japan has become one of the world's top countries for longevity, and the increase in average life expectancy is accompanied by a sharp rise in older population aged 65 years and above to approximately 28%. This study aimed to examine the changes in major health-related measures including physical constitution, physical function, and functional capacity of community-dwelling Japanese older people in the last decade. From the data of 13 longitudinal cohort studies on aging conducted in Japan with a total of 13,441 older subjects, the present study analyzed the changes in six indices that are related to health and functioning of the older people; height, weight, BMI, walking speed, grip strength, and instrumental ADL, between 2007 (± 2 years) and 2017 (± 2 years). Comparison of data for the two periods between subjects matched for age group and gender evidently showed better health status and a slower decline in most of the health-related measures in 2017 compared to a decade ago. The results of the present study indicate that the phenomenon of "rejuvenation" is occurring among the new generation of Japanese older adults, and the importance of this older population as a social resource in the super-aged society should be re-acknowledged.

    BACKGROUND: Walking is the most important mode of human locomotion; however, the ability to walk often decreases with age. Age-related differences in lower-limb kinematics during gait may differ depending on sex. However, the question of the compounded effects of age and sex on gait kinematics remains unsolved. RESEARCH QUESTION: The present study aimed to clarify the interaction between age and sex in differences in gait kinematics of community-dwelling middle-age and older individuals. METHODS: This study included 836 community-dwelling middle-age and older adults (61.8 % female). Joint motion during comfortable gait was measured using magnetic and inertial measurement units. Hip, knee, and ankle joint angles were calculated in the sagittal plane. Participants were divided into four groups according to age: 50-59, 60-69, 70-79, and 80-89 years. The interaction of sex and age on spatiotemporal gait parameters and the peak value of joint angles was analyzed using two-way analysis of variance (ANOVA) and Tukey's post hoc test. RESULTS: Gait speed (F = 43.92, P < 0.001), step length (F = 73.00, P < 0.001), hip extension (F = 12.89, P = 0.002), knee flexion (F = 39.99, P < 0.001), and ankle plantar flexion (F = 27.43, P < 0.001) significantly decreased with age. Significant differences according to sex were observed in all parameters except gait speed. Significant age and sex interaction effects were observed for knee flexion (F = 4.97, P = 0.002) and ankle dorsiflexion (F = 4.04, P = 0.007). SIGNIFICANCE: A significant interaction effect of age and sex was observed for peak angle of knee flexion and ankle dorsiflexion during gait. In particular, the knee flexion angle among females during gait began to decrease from 60 years of age, and the decreasing trend was faster and more prominent than that among males.

    OBJECTIVES: We aimed to determine if achieving a 10-m walk target within the first week of stroke onset correlates with independent outdoor walking at discharge and discharge to home for patients with stroke. MATERIALS AND METHODS: This study included 226 patients transferred to the subacute rehabilitation hospital (SRH) between January 2018 and March 2021. Data obtained from hospital records included age, sex, stroke type, lesion side, body mass index, presence of acute treatment, length of days from onset to physical therapy intervention, National Institutes of Health Stroke Scale, length of hospital stay, Functional Independence Measure score, and the ability to complete the 10 m walk target within the first week of stroke onset. The primary outcomes were independent outdoor walking ability and discharge destination from the SRH. A logistic regression analysis was performed to determine if the 10 m walking ability correlated with the outdoor walking ability and discharge destination. RESULTS: Compared with the inability to walk 10 m, walking 10 m independently walking within the first week of stroke onset correlated with the ability to walk independently outdoors at discharge (odds ratio [OR]: 4.38, p = 0.003) and being discharged home (OR: 4.52, p = 0.002), whereas, walking 10 m with assistance was associated with being discharged home (OR: 3.09, p = 0.043). CONCLUSIONS: The ability to walk 10 m within the first week of stroke onset may be a helpful marker for prognosis.

    <p>【Objective】</p><p>In recent years, the use of virtual reality technology has spread rapidly in the medical and welfare fields and has also found its way in rehabilitation. Nintendo Wii<sup>Ⓡ</sup> is one of the most widely used virtual reality systems in the world owing to its ease of use, cost, and accessibility at home. However, to date, the reports of its use in patients with brain tumors are limited. Therefore, this study aimed to evaluate the effectiveness of Wii<sup>Ⓡ</sup>‐based rehabilitation for patients with brain tumors.</p><p>【Methods】</p><p>A scoping review was conducted using PubMed (MEDLINE), the Cochrane Library, and Ichu‐shi Web databases as well as a hand search of the English and Japanese literature from 2006 to 2021. Prior to the literature search, keywords and synonyms related to brain tumors and Wii<sup>Ⓡ</sup> were identified, and a search formula was developed to include them. Articles were selected based on a specific inclusion and exclusion criteria.</p><p>【Results】</p><p>Of the 155 identified studies, three were eligible for review. Subjects included pediatric and adult patients with brain tumors. Wii<sup>Ⓡ</sup>‐based rehabilitation was shown to be effective for physical function, activities of daily living (ADL), motivation for physical activity, and distraction from the hospital environment for patients with brain tumors.</p><p>【Conclusion】</p><p>Wii<sup>Ⓡ</sup>‐based rehabilitation was suggested to improve physical function, ADL, and mental status in patients with brain tumors. However, the number of the studies included━only three━was insufficient to demonstrate the efficacy of Wii<sup>Ⓡ</sup>‐based rehabilitation in terms of the study design. We therefore hope that more rigorously designed intervention studies will validate its efficacy.</p>

    OBJECTIVES: This study aimed to clarify the association between changes in satisfaction with meaningful activities and the occurrence of depressive symptoms before and during the coronavirus disease 2019 (COVID-19) pandemic. DESIGN: A population-based prospective cohort study (Tarumizu Study). SETTING AND PARTICIPANTS: A total of 231 community-dwelling older adults aged ≥65 years without depressive symptoms at baseline. METHODS: The participants completed baseline (June to December 2018, before the COVID-19 pandemic) and follow-up (September to December 2021, during the COVID-19 pandemic) assessments. Depressive symptoms were assessed using the 15-item Geriatric Depression Scale (GDS-15) and defined by a GDS-15 score of ≥5. Participants selected meaningful activities from the 95 activities included in the Aid for Decision-Making in Occupation Choice, and their satisfaction levels were evaluated. Satisfaction with the most meaningful activities was assessed as to whether it was maintained/improved or decreased at follow-up. RESULTS: In the follow-up survey, 31 (14.3%) participants reported the occurrence of depressive symptoms. Compared with before the COVID-19 pandemic, the rates of meaningful activities during the COVID-19 pandemic decreased for interpersonal interaction and social life and increased for leisure, sports, self-care, and domestic life. Logistic regression analysis revealed that changes in satisfaction with meaningful activity were associated with the occurrence of depressive symptoms after adjusting for demographic variables, baseline GDS scores, cognitive and physical status, and instrumental activities of daily living (odds ratio, 2.78; 95% confidence interval, 1.17-6.59, P = .020). CONCLUSIONS AND IMPLICATIONS: To avoid decreasing satisfaction with meaningful activities, supporting older adults may be protective against the occurrence of depressive symptoms. Our findings highlight the need for health care professionals to not only encourage older adults to participate in activities for their mental health but also consider whether the activities are meaningful or satisfying for them.

    This study aimed to characterize cognitive function examined using Cognitive-related Behavioral Assessment (CBA) in activities of daily living (ADLs). According to CBA severity at discharge, 791 patients were assigned to five groups (most severe, severe, moderate, mild, and normal). The total scores for Functional Independence Measure (FIM) motor items were compared for each group. Multiple logistic regression analysis was performed to clarify the association between CBA severity and independence in ADL items. Independence in each ADL according to CBA severity was 0–4.8%, 26.8–45.0%, 84.3–91.0%, and 97.2–100% for all ADLs in the most severe to severe, moderate, mild, and normal groups, respectively. Significant differences were found in the FIM motor score according to CBA severity between the groups (p < 0.01). A mild or normal CBA was associated with a higher odds ratio (OR) for dressing the upper body (OR = 21.90; 95% confidence interval (CI), 13.50–35.70), bladder management (OR = 11.60; 95% CI, 7.21–18.60), transfers to the bed/chair/wheelchair (OR = 18.30; 95% CI, 11.40–29.40), transfers to the toilet (OR = 18.30; 95% CI, 11.40–29.30), and walking (OR = 6.60; 95% CI, 10.60–26.10). A CBA severity greater than mild (23 points) was associated with independence in ADLs that are important for discharge to home.

    In general, the perception of behavior change may be associated with habitual exercise. However, this association might not be well-understood due to the state of emergency of the COVID-19 pandemic. This study collected data from 1499 internet users aged 20–86 years living in Japan who participated in the online survey from 26 to 27 February 2021. Having a perception of behavior change was defined as preparation, action, and maintenance of the transtheoretical model. The habitual exercise was defined as 600 metabolic equivalent min/week or more based on the International Physical Activity Questionnaire. Multivariate logistic regression analysis was used to calculate the odds ratio of habitual exercise and a 95% confidence interval was estimated after adjusting for related factors. We found that perception of behavior change was positively associated with habitual exercise (adjusted odds ratio = 2.41, 95%CI = 1.89–3.08), and similar associations were found in states of emergency (2.69, 1.97–3.69) and non-emergency (2.01, 1.34–3.01). Moreover, women were negatively associated in all analyses with habitual exercise compared to men (0.63, 0.49–0.80; 0.65, 0.44–0.96; 0.62, and 0.45–0.84, respectively). Thus, the perception of behavior change may be involved in the implementation of habitual exercise, suggesting that women face difficulties in engaging in habitual exercise.

    Older adults are more likely to have age-related sleep problems, which may result in the reduction of cognitive functions. This study was designed to examine the relationship between sleep onset problem and subjective cognitive complaints (SCC) among community-dwelling older adults during the coronavirus disease 2019 pandemic. In this study, 186 older adults aged 65 and above were enrolled and were instructed to respond to an online survey. This survey comprised questions regarding sleep quality (four items such as sleep duration, use of sleep medication), SCC (six domains), and sociodemographic information (eight items such as age, gender, stress condition). We classified the participants into two groups according to the presence or absence of sleep onset problem and examined the relationship between each SCC domain. The sleep onset problem (+) (n = 70) group had significantly higher frequency of scheduled memory decline, misplacement, disorientation in time, word recall decline, and forgetfulness. Furthermore, the sleep onset problem affected the participants' scheduled memory after adjusted for potential covariates (OR, 2.28; 95%CI, 1.13-4.73; p = 0.02). Older adults with sleep onset problem may need to be evaluated for SCC and supported in term of both sleep status and SCC.

    <p>【はじめに、目的】</p><p>座位行動(Sedentary Behavior:以下、SB)は、エネルギー消費量が1.5METs 以下の覚醒行動であり、SBの蓄積は非感染性疾患の発生や死亡率の増加など、様々な有害事象と関連する。昨今、活動量計を使用し、座位中断回数(以下、Break数)や1回当たりのSBの連続量(以下、SB Bout)など、より詳細なSBの様式を分析した研究が報告されている。SB時間の延長は、サルコペニアのリスクを増大させることが報告されているが、これまでは質問紙にてSB時間を評価した研究が多く、活動量計にて評価される詳細なSBの様式とサルコペニアの関係性は不明な点が多い。これらが明らかとなれば、サルコペニアの新たな対策の知見となる可能性がある。本研究では、サルコペニアに対するBreak数と長時間SB Boutの関係性について検討した。</p><p>【方法】</p><p>地域コホート研究(垂水研究2018)の参加者において、三軸加速度計(HJA-750C Active style Pro オムロンヘルスケア社)にて活動量を計測した地域在住高齢者265名のうち、主要データに欠損がなく基準を満たした208名(74.7±5.9歳、女性59.3%)を対象とした。活動量データの有効基準は週4日以上かつ1日10時間以上とし、活動量の評価項目は、SB時間(分/日)、中高強度身体活動(以下、MVPA)時間(分/日)、Break数(回/座位1時間)、30分以上SB Bout 数、60分以上SB Bout数(いずれも回/日)とした。計測機器の装着時間(分/日)も計測した。サルコペニアは四肢骨格筋指数、握力、歩行速度にて判定した。統計解析は、サルコペニア群と非サルコペニア群の2群間比較を実施した。また、サルコペニアの有無を従属変数、Break数と30分以上、60分以上のSB Bout数を独立変数とした3通りのロジスティック回帰分析を行った。共変量は年齢、性別、MVPA時間とした。</p><p>【結果】</p><p>対象者のサルコペニアの割合は17.3%であった。マンホイットニー検定の結果、Break数は非サルコペニア群7.9(6.3 ‐9.4)回、サルコペニア群6.7(4.7-8.1)回であり、非サルコペニア群が有意に多く(p<0.01)、60分以上SB Bout数は非サルコペニア群0.9(0.6-1.3)回、サルコペニア群1.4(0.8-1.6)回と有意にサルコペニア群の回数が多かった(p<0.01)。ロジスティック回帰分析の結果、Break数とサルコペニアの関連は、オッズ比0.81(95%CI:0.68-0.95)、60分以上SB Bout数とサルコペニアの関連は、オッズ比2.08(95%CI:1.27-3.47)であり、いずれも有意にサルコペニアと関連していた。30分以上SB Bout数はサルコペニアと有意な関連を認めなかった。</p><p>【結論】</p><p>MVPA時間と独立して、1時間当たりの座位中断回数と60分以上連続する座位行動の回数はサルコペニアと関連していた。高齢者のサルコペニアに対する理学療法を講じる上で身体活動量の増大は重要であるが、日常生活における座位行動の中断や縮減に着目した指導・介入が重要である事が示唆された。</p><p>【倫理的配慮,説明と同意】</p><p>鹿児島大学疫学研究等倫理委員会の承認(170351疫)を得て実施した。ヘルシンキ宣言に基づき、対象者には研究内容について口頭と書面にて説明し同意を得た。</p>

    Patients with heart disease are more likely to experience social frailty due to physical inactivity, which may affect meaningful activities such as hobbies. This study aimed to investigate (1) the association between heart disease and social frailty in community-dwelling older adults and (2) the characteristics of meaningful activities in community-dwelling older adults with heart disease. Data from 630 older adults who participated in a community-based health survey were obtained, including clinical history, meaningful activities, social frailty and psychosomatic functions. Participants were divided into two groups: those with heart disease (n = 79) and those without (n = 551), and comparisons were made. Social frailty was observed in 23.7% of participants with heart disease, and logistic regression revealed significant associations with heart disease and social frailty after adjusting for potential covariates (OR, 1.97; 95% CI, 1.06 3.67; p = 0.032). Participants with heart disease did not differ significantly in terms of satisfaction or performance; their frequency of engagement in meaningful activities was significantly lower than without heart disease (p = 0.041). These results suggest that heart disease and social frailty are associated in community-dwelling older adults, and that this demographic is inclined to engage in meaningful activities less frequently.

    Bone and muscle mass loss are known to occur simultaneously. The alpha-actinin three (ACTN3) genotype has been shown to potentially affect bone and muscle mass. In this study, we investigated the association between the ACTN3 genotype and bone and muscle mass loss in community-dwelling adults aged ≥ 60 years. This study was a cross-sectional analysis of data from 295 participants who participated in a community health checkup. The ACTN3 genotypes were classified as RR, RX, or XX types. Bone mass loss was defined as a calcaneal speed of sound T-score of &lt;-1.32 and &lt;-1.37, and muscle mass loss was defined as an appendicular skeletal muscle index of &lt;7.0 kg/m2 and &lt;5.7 kg/m2 in men and women, respectively. The percentages of XX, RX, and RR in the combined bone and muscle mass loss group were 33.8%, 30.8%, and 16.7%, respectively, with a significantly higher trend for XX. Multinomial logistic regression analysis showed that XX had an odds ratio of 3.00 (95% confidence interval 1.05-8.54) of being in the combined bone and muscle mass loss group compared to the RR group (covariates: age, sex, grip strength, and medications). The ACTN3 genotype of XX is associated with a higher rate of comorbid bone and muscle mass loss. Therefore, ACTN3 genotyping should be considered for preventing combined bone and muscle mass loss.

    <p>糖尿病,高血圧,肥満,喫煙などの生活習慣に関わる要因は,認知症の重大な危険因子とされている.とくに,糖尿病は認知症および認知機能障害の発生リスクを増大させるだけでなく,認知機能が低下している中高齢者では将来の糖尿病発症リスクを増大させることが報告されており,双方からの予防対策が重要である.さらに,糖尿病に至らずとも,HbA1c が5.7~6.4%程度の前糖尿病に該当する者でも認知症の発症リスクが高く,さらには脳萎縮の進行が懸念されている. また,糖尿病を合併するフレイル高齢者では,要介護の発生リスクが増大することが報告されており,糖尿病の診断基準に該当しなくとも,前糖尿病の段階からフレイルや身体機能の低下を惹起するリスクが高いことが示唆されている.このように,糖尿病の診断に至らずとも,その前段階である前糖尿病においても,認知症およびフレイルの発生リスクは高く,より早期からの血糖コントロールおよび重症化の予防が重要であろう. 認知症の発症者では,発症の10~12 年程前から身体活動量は低下してくることが指摘されており,継続した身体活動の促進に取り組むことが望ましい.とくに,65 歳以上の高齢者では,座位時間を身体活動(強度は問わない)に置き換えることや,1 週間で150~300 分以上の中強度の有酸素運動,もしくは75~150 分の高強度の有酸素運動に取り組むことが推奨されている.有酸素運動を中心とした身体活動の向上によって,認知症の発症の予防や遅延に効果が期待されている.認知機能の維持・改善に対するより効果的な運動療法としては,運動による身体活動の促進のみではなく,知的な刺激が伴う活動を付加することが推奨される.とりわけ,認知機能の低下が疑われる状態においては,運動のみによる介入では認知機能の改善には限界があると言わざるを得ず,知的な刺激の伴う活動を加えることで認知機能が維持・改善することが期待されている. フレイルに対しては,筋力トレーニングを中心として,有酸素運動,柔軟運動,バランス運動を含めた多面的な運動が推奨されている.血糖コントロールの改善を目指すうえでは,具体的な運動方法の提示とともに,いかに継続できるかの支援も重要であろう.</p>

    Background: As the population ages, it is important to consider whether older adults tend to have healthier lives. This study examined temporal trends in cognitive function among community-dwelling Japanese older adults. Methods: The data source for this study was Integrated Longitudinal Studies on Aging in Japan (ILSA-J). We collected representative values for the Mini-Mental State Examination (MMSE) score obtained in 2010 and 2017; mean, standard deviation, and prevalence of ≤23 as cognitive impairment and ≥28 as intact cognitive function. Six cohorts (n=8,575) in 2010 and seven cohorts (n=6,089) in 2017 were included (age range 65-89). One-group meta-analyses were conducted to calculate pooled means of MMSE scores, the pooled prevalence of MMSE scores ≤23 and ≥28, and 95% confidence intervals (CIs). Results: The mean MMSE score was higher in 2017 than in 2010 for all age groups in both men and women. The prevalence of MMSE ≤23 was lower in 2017 than in 2010 for all age groups for men and was lower in 2017 than in 2010 for all age groups other than for women aged 75–79 years. The prevalence of MMSE ≥28 was higher in 2017 than in 2010 for all age groups in both men and women. In addition, the pooled means of years of education was lower in 2010 than in 2017, which might be an explanatory factor. Conclusions: This study suggests that the cognitive function of community-dwelling Japanese older adults has improved in recent years. Future studies need to identify factors associated with the improvement.

    地域在住高齢者におけるアパシーとフレイルとの横断的な関連について検討した。健康診断調査(垂水調査)に参加した地域在住高齢者882名(平均74.4±6.4歳、女性62.1%)を対象とした。アパシーはGeriatric Depression Scale-3Aで評価し、フレイルは基本チェックリスト(下位尺度;日常生活関連動作、運動器機能、低栄養状態、口腔機能、閉じこもり、認知機能)で評価した。その結果、209名(23.7%)でアパシーが認められた。交絡因子調整後の多項ロジスティック回帰分析の結果、アパシーはプレフレイルおよびフレイルと有意に関連していた。アパシーを有する高齢者では有さない高齢者と比較して、基本チェックリストの日常生活関連動作、運動器機能、口腔機能、認知機能に問題を呈する割合が有意に高かった。以上から、包括的なフレイル評価の重要性が示され、アパシーは老年期の健康に広範かつ有害な影響を及ぼす可能性が示唆された。

    Objective: The purpose of this study was to determine the relationship between the measured mass of the calcaneus bone and the number of stairs used by community-dwelling older adults. Methods: Data obtained from 169 older adults who participated in a community-based health-check survey (Tarumizu Study 2018) were analyzed. Bone mass was measured using the speed of sound of the calcaneal bone and the obtained values were considered to be low when the percentage of the %YAM of the SOS was ≤ 70%. The frequency of stair usage was classified into two groups: 0 and 1 or more times per day at home, and three sub-groups comprising of: 0–2, 3–7, and 8 or more times per week outside home. Results: The results of logistic regression analysis, in which the dependent variable was the presence or absence of bone loss, and the independent variable was the number of stairs used, showed no significant association with the number of stairs used at home. The number of times the stairs were used outside home was set at 0–2 times as a reference, and bone loss was significantly reduced by 8 times or more (odds ratio 0.32, 95% confidence interval 0.11 –0.97, p = 0.045, covariates: age, gender, ASMI, grip strength, walking speed). Conclusion: It was suggested that the frequent use of stairs outside the home may aid in suppressing bone loss. It could be concluded that the use of stairs in activities including going out may affect bone mass as the frequency of stair usage in the house is not relevant.

    Aim To investigate whether the type and frequency of social interaction during the state of emergency due to coronavirus disease were associated with self-rated health (SRH) after the state of emergency. Methods Data from a cross-sectional study were collected for 889 oldest-old adults in Bibai City, Hokkaido, Japan. In total, 612 participants (mean age: 83.0 +/- 4.3 years; women: 51.8%) were included in the analysis, taking biological sex into account. The self-reported questionnaire included questions about demographic variables, SRH (July 2020, after the emergency), and the type and frequency of social interaction (March 2020, during the state of emergency). Results There was no significant association between social interaction and SRH in men (P > 0.05). Women who had social interactions (both face-to-face and non-face-to-face) more than once a week during the state of emergency reported higher SRH after the emergency than those who did not (odds ratio 2.17, 95% confidence interval 1.07-4.41). Conclusions Having both types of interaction more than once a week during the state of emergency was related to higher SRH after the emergency among oldest-old women. It is suggested that having opportunities for both types of interaction at least once a week would potentially be beneficial for high SRH in women, even in situations where the declaration of a state of emergency restricts face-to-face interaction.

    Blood pressure variability (BPV) is associated with the prognosis of cardiovascular diseases. However, it is unclear how BPV is related to various organs. The aim of this study is to investigate the association between BPV and multiple organ functions. A total of three hundred fifteen participants (114 males; mean age: 70 ± 9 years) participated in a community health checkup held in Tarumizu City. Home blood pressure (BP) was measured using a HEM-9700T (OMRON Healthcare, Kyoto, Japan). Day-to-day BPV was evaluated by the coefficient of variation (CV) of home BP measured in the morning for one month. N-terminal pro B-type natriuretic peptide (NT-pro BNP) and high-sensitivity (hs-)troponin T were measured as cardiac biomarkers. Liver stiffness and renal function were evaluated using the Fibrous-4 (Fib4) index and estimated glomerular filtration rate (eGFR), respectively. NT-pro BNP and hs-troponin T were divided by the median value. Fib4 index greater than 2.67 and eGFR less than 60 mL/min/1.73 m2 were defined as high Fib4 index and low eGFR, respectively. In a multivariable logistic regression analysis, the CV of systolic BP was significantly associated with high NT-pro BNP, high Fib 4 index, and low eGFR, but not with high hs-troponin T. In contrast, the CV of diastolic BP was not associated with low eGFR, and the other three biomarkers had the same results as systolic BP. In conclusion, day-to-day BPV of systolic BP is independently associated with NT-pro BNP, eGFR, and Fib4 index, but not with hs-troponin T. In contrast, diastolic BPV was not found to be associated with eGFR.

    AIM: To clarify prevalence of social frailty among older adults living in a rural Japanese community, and factors associated with social frailty status. METHODS: In total, 322 adults aged ≥65 years living in a Japanese rural community took part in the study from 2018 to 2020. Social frailty was defined as deficiencies of: (i) living alone; (ii) talking with someone every day; (iii) feeling helpful to friends or family; (iv) going out less frequently compared with last year; and (v) visiting friends sometimes. Social frail status was categorized as robust (0), social prefrail (1), and social frail (≥2), according to the summated score of Makizako's criteria. Multiple logistic regression analysis was applied to clarify factors associated with social frailty status. RESULTS: Final samples were classified into 68 persons with social frailty, 98 persons with social prefrailty and 147 persons as robust. We observed the prevalence of social frailty (21.7%) and social prefrailty (31.3%) and the GDS-15 had significantly high scores in the social frail groups. Social frailty was significantly associated with the GDS-15 score (odds ratio, 1.33; 95% CI, 1.19-1.49) and TMT-A (odds ratio, 1.04; 95% CI, 1.01-1.08) and GDS-15 (odds ratio, 1.13; 95% CI, 1.03-1.26) were extracted as independent variables of social prefrail status, with adjustment for demographics, polypharmacy and lifestyle-related diseases. CONCLUSIONS: Our results suggest that social frailty tends to be increasing gradually in a Japanese rural area, and social prefrailty might be potentially associated with attentional function, as well as the GDS-15 score.

    Nutritional factors, including low protein intake and poor dietary variety, affect age‐associated impairment in physical performance resulting in physical frailty. This cross‐sectional study investigated the association between intake frequency of major high protein foods and both physical performance and higher‐level functional capacity using the food frequency score (FFS) and high protein food frequency score (PFFS) among community‐dwelling older adults. The data of 1185 older adults categorized into quartiles based on FFS and PFFS were analyzed. After adjusting for covariates, FFS and PFFS were significantly associated with physical performance [FFS, usual gait speed (p for trend = 0.007); PFFS, usual gait speed (p for trend < 0.001), maximum gait speed (p for trend = 0.002), timed up and go (p for trend = 0.025)], and higher‐level functional capacity [FFS (p for trend < 0.001); PFFS (p for trend < 0.001)]. After excluding PFFS data, the participants’ scores were associated with only higher‐level functional capacity. Multi‐regression analysis with higherlevel functional capacity as the covariate showed that FFS and PFFS were significantly correlated with physical performance. Hence, improving food intake frequency, particularly that of high protein foods, and dietary variety may help maintain higher‐level functional capacity and physical performance in community‐dwelling older adults.

    Background: Recent longitudinal studies have reported proportion of frailty transition in older individuals during the COVID-19 pandemic. Our study aimed at clarifying the impact of social frailty in community-dwelling older adults during the COVID-19 pandemic and at identifying factors that can predict transition to social frailty. Methods: We performed this study from 2019 (before declaration of the state of emergency over the rising number of COVID-19 cases) to 2020 (after declaration of the emergency). We applied Makizako’s social frail index to our study subjects at the baseline and classified into robust, social prefrailty, and social frailty groups. Multiple logistic regression analysis was performed using robust, social prefrailty, or social frailty status as dependent variable. Results: Analysis by the Kruskal–Wallis test revealed significant differences in the score on the GDS-15 among the robust, social prefrailty, and social frailty groups (p < 0.05). Furthermore, multiple regression analysis identified a significant association between the social frailty status and the score on GDS-15 (odds ratio, 1.57; 95% confidence interval (95% CI), 1.15–2.13; p = 0.001). Conclusion: The increase in the rate of transition of elderly individuals to the social frailty group could have been related to the implementation of the stay-at-home order as part of the countermeasures for COVID-19. Furthermore, the increased prevalence of depressive symptoms associated with the stay-at-home order could also have influenced the increase in the prevalence of social frailty during the COVID-19 pandemic.

    BACKGROUND: Poor sleep quality has a negative effect on pain among older adults. During the coronavirus disease 2019 (COVID-19) state of emergency, lifestyle changes can cause psychologic stressors and lead to poor sleep quality. AIM: This study examined whether sleep quality status was associated with low back or knee pain changes during the COVID-19 state of emergency among community-dwelling Japanese old-old adults. DESIGN: Cross-sectional investigation. METHODS: In July 2020, during the COVID-19 epidemic, we conducted a postal survey for old-old adults aged ≥77 years and collected data on 597 participants. For those who had low back or knee pain at the time of the survey (in July), characteristics such as low back pain, knee pain, changes in pain status, and sleep quality status during the COVID-19 state of emergency (in March) were assessed. RESULTS: Data from 597 participants showed the prevalence of low back pain (50.6%) and knee pain (40.7%) in July. Of those with low back or knee pain, 374 had pain changes during the state of emergency, with 12.3% worsening. Of these, 23.9% had poor sleep quality in March compared to non-change (p = .008). In a multivariate logistic regression model adjusted for potential confounders, poor sleep quality was significantly associated with pain worsening (odds ratio 2.80, 95% confidence interval 1.26-6.22). CONCLUSIONS: During the COVID-19 state of emergency, poor sleep quality was associated with worsening low back or knee pain. This may indicate the need to pay attention to poor sleep quality to prevent the exacerbation of pain among old-old adults.

    BACKGROUND: Falls and fear of falling (FoF) inhibit healthy longevity and have been suggested to be associated with cognitive function. However, the domains of cognitive function that are associated with them remain controversial. It is speculated that clarifying this will help in the assessment of health status and interventions in the community. AIM: To analyse the associations between fall history and FoF and multidimensional cognitive function in independent community-dwelling older adults. METHODS: The data from 9759 (73.3 ± 5.4 years, 59.9% women) older individuals enrolled in the cross-sectional ORANGE study were analysed. Simple questions were used to assess fall history in the past year and current FoF. Assessments of multidimensional cognitive function were performed using the National Center for Geriatrics and Gerontology-Functional Assessment Tool (NCGG-FAT) to evaluate memory, attention, executive function, and processing speed. The independent associations of fall history and FoF with multidimensional cognitive function were assessed using multivariate linear regressions adjusted for potential confounding variables. RESULTS: A total of 18.3% and 35.4% of participants presented with fall history and FoF, respectively. Fall history (p = 0.008) and FoF (p = 0.002) were significantly associated with memory. FoF, but not fall history was associated with attention (p = 0.004), executive function (p < 0.01), and processing speed (p < 0.01). CONCLUSION: In independent community-dwelling older adults, fall history was associated only with the memory domain; in contrast, fear of falling was associated with multidimensional cognitive function. This study provides weak evidence suggesting the need to assess falls and FoF in all situations involving independent community-dwelling older adults.

    Few studies have investigated the relationship between nutritional status and comprehensive assessment of oral hypofunction, especially protein intake-related sarcopenia. Thus, we explored these relationships in a large-scale cross-sectional cohort study using the seven-item evaluation for oral hypofunction and Diet History Questionnaire for nutritional assessment. We used the data from 1004 individuals who participated in the 2019 health survey of the residents of Tarumizu City, Kagoshima Prefecture, Japan for analysis. We found that individuals with oral hypofunction were significantly older with a lower skeletal muscle index. Although there were few foods that had a sig-nificant difference between the groups with and without oral hypofunction, the consumption of beans and meats was significantly lower in women and men in the oral hypofunction group, respectively. According to the lower limit of the tentative dietary goal defined in Japan, comprehensive evaluation of oral hypofunction was significantly and independently associated with protein intake in both men and women (odds ratio, 1.70; 95% confidence interval, 1.21–2.35). In conclusion, we found that oral hypofunction was associated with targeted protein intake for sarcopenia and frailty prevention in middle-aged and older community-dwelling adults. Comprehensive evaluation of oral function with intervention in cases of hypofunction could inform clinicians to better prevent sarcopenia.

    The purpose of this cross-sectional study was to analyse the differences in meaningful activities and psychosomatic function depending on the driving status of community-dwelling older adults. Data from 594 older adults were obtained, including activities meaningful to individuals and psychosomatic functions, such as grip strength, depression, cognitive function, and ability of activity. Participants were divided into active driving (n = 549) and after driving cessation (n = 45) groups. In addition, the active driving group was operationally divided into three groups: high-frequency group (n = 387), medium group (n = 119), and infrequent group (n = 42). In the after driving cessation group, grip strength, and Japan Science and Technology Agency Index of Competence scores were significantly lower. Furthermore, the proportion of apathy and physical and social frailty was significantly higher in the after driving cessation group. Regarding meaningful activity, domestic life scores in the after driving cessation group were significantly higher than those of the active driving group. Decreased driving frequency in the active driving group was associated with weak muscle strength, lack of interest, and low activity. This study demonstrated that meaningful activity differed based on the driving status. Hence, we should support the activities of older adults who are considering driving cessation.

    OBJECTIVES: The purpose of this cross-sectional study was to examine the association between cognitive frailty (CF) and higher-level competence among community-dwelling older adults. METHODS: Data from 871 older adults (aged ≥ 65 years, mean age 74.3 years, 61.5% women) who had participated in a community-based health check survey (Tarumizu Study 2018-2019) were analyzed. CF was defined as comorbid physical frailty and mild cognitive impairment (MCI). We defined physical frailty as either slow walking speed or poor grip strength. MCI was defined as values below the age- and education-adjusted reference threshold in several tests. Participants were categorized into four groups: robust, physical frailty, MCI, and CF. Higher-level competence was assessed using the Japan Science and Technology Agency Index of Competence (JST-IC). The JST-IC consists of 16 items and four subscales (technology usage, information practice, life management and social engagement). The bottom 20-30% score of the JST-IC and each subscale corresponded to poor higher-level competence. RESULTS: The prevalence of CF was 14.4%. Multivariate logistic regression analysis showed that, CF was significantly associated with poor higher-level competence (odds ratio 1.92, 95% confidence interval 1.18-3.13) after adjusting for covariates. Using a similar analysis to assess the JST-IC subscales, CF was associated with limitations on technology usage (odds ratio 2.29, 95% confidence interval 1.36-3.85) and low social engagement (odds ratio 1.62, 95% confidence interval 1.00-2.61). CONCLUSIONS: This study suggests that CF is associated with poor higher-level competence, especially limitations on technology usage and low social engagement.

    This study aimed to clarify the relationship between leg extension angle and knee flexion angle during gait in older adults. The subjects of this cross-sectional study were 588 community-dwelling older adults (74.6 ± 6.1 y). Segment angles and acceleration were measured using five inertial measurement units during comfortable gait, and bilateral knee and hip joint angles, and leg extension angle, reflecting whole lower limb extension at late stance, were calculated. Propulsion force was estimated using the increase in velocity calculated from anterior acceleration of the sacrum during late stance. Correlation analysis showed that leg extension angle was associated with knee flexion angle at swing phase and hip extension angle and increase in velocity at late stance (r = 0.444-508, p < 0.001). Multiple regression analysis showed that knee flexion angle at mid-swing was more affected by leg extension angle (β = 0.296, p < 0.001) than by gait speed (β = 0.219, p < 0.001) and maximum hip extension angle (β = -0.150, p < 0.001). These findings indicate that leg extension angle may be a meaningful parameter for improving gait function in older adults due to the association with knee kinematics during swing as well as propulsion force at late stance.

    The aim of this cross-sectional study was to examine the correlations between gait regularity, cognitive functions including cognitive domains, and the mild cognitive impairment (MCI) in community-dwelling older people. This study included 463 older adults (63.4% women, mean age: 74.1), and their step and stride regularity along the three-axis components was estimated from trunk acceleration, which was measured by inertial measurement units during a comfortable gait. Four aspects of cognitive function were assessed using a tablet computer: attention, executive function, processing speed, and memory, and participants were classified into those with or without MCI. The vertical component of stride and step regularity was associated with attention and executive function (r = -0.176--0.109, p ≤ 0.019), and processing speed (r = 0.152, p < 0.001), after it was adjusted for age and gait speed. The low vertical component of step regularity was related to the MCI after it was adjusted for covariates (OR 0.019; p = 0.016). The results revealed that cognitive function could affect gait regularity, and the vertical component of gait regularity, as measured by a wearable sensor, could play an important role in investigating cognitive decline in older people.

    ABSTRACT: Understanding the relationship between pain and physical activity (PA) levels is beneficial for maintaining good health status. However, the impact of pain on changes in PA during the coronavirus disease 2019 (COVID-19) pandemic is unknown. The purpose of this study was to examine whether PA levels pre-, during, and post-COVID-19 state of emergency differ between Japanese adults who had pain after the COVID-19 state of emergency and those who did not.Data were collected from a cross-sectional online survey conducted between October 19 and 28, 2020. The analytic sample consisted of 1967 Japanese adults aged ≥40 years who completed the online survey. Participants completed questionnaires on the presence of pain and duration of PA, defined as the total PA time per week based on activity frequency and time. Participants were asked to report their PA at 3 time points: October 2019 (before the COVID-19 pandemic), April 2020 (during the COVID-19 state of emergency), and October 2020 (after the COVID-19 state of emergency).Among participants aged ≥60 years who reported pain in October 2020, the total PA time was significantly lower than participants who did not report having pain. Furthermore, the total PA time in April 2020 was significantly lower than that in October 2019; however, no significant difference in total PA time was observed between April and October 2020. Among participants aged 40 to 59 years, no significant differences were observed in total PA times at the 3 time points between those with and without pain. In addition, the total PA time in October 2020 significantly increased compared to that in April 2020, although it significantly decreased in April 2020 compared to October 2019.This study suggests that older adults with pain have lower PA levels after the COVID-19 state of emergency.

    Background Frailty is conceptualized as an accumulation of deficits in multiple areas and is strongly associated with the prognosis of heart failure (HF). However, the social domain of frailty is less well investigated. We prospectively evaluated the clinical characteristics and prognostic impact of social frailty (SF) in elderly patients with HF. Methods and Results FRAGILE-HF (prevalence and prognostic value of physical and social frailty in geriatric patients hospitalized for heart failure) is a multicenter, prospective cohort study focusing on patients hospitalized for HF and aged ≥65 years. We defined SF by Makizako's 5 items, which have been validated as associated with future disability. The primary end point was a composite of all-cause death and rehospitalization because of HF. The impact of SF on all-cause mortality alone was also evaluated. Among 1240 enrolled patients, 825 (66.5%) had SF. During the 1-year observation period after discharge, the rates of the combined end point and all-cause mortality were significantly higher in patients with SF than in those without SF (Log-rank test: both P < 0.05). SF remained as significantly associated with both the combined end point (hazard ratio, 1.30; 95% CI, 1.02-1.66; P = 0.038) and all-cause mortality (hazard ratio, 1.53; 95% CI, 1.01-2.30; P = 0.044), even after adjusting for key clinical risk factors. Furthermore, SF showed significant incremental prognostic value over known risk factors for both the combined end point (net-reclassification improvement: 0.189, 95% CI, 0.063-0.316, P = 0.003) and all-cause mortality (net-reclassification improvement: 0.234, 95% CI, 0.073-0.395, P = 0.004). Conclusions Among hospitalized geriatric patients with HF, two thirds have SF. Evaluating SF provides additive prognostic information in elderly patients with HF.

    OBJECTIVE: The present study aimed to examine the prospective associations of physical frailty with future falls and fear of falling (FOF) among community-dwelling older adults. METHODS: A prospective cohort study with a 48-month follow-up was conducted in a Japanese community. Participants were 2469 community-dwelling older adults aged 65 years or older who completed baseline and follow-up assessments at intervals of 48 ± 2 months. Primary outcomes were recent falls (defined as at least one fall within the past year) and FOF (determined by response to "Are you afraid of falling?") at follow-up survey. Physical frailty, operationalized by the frailty phenotype (slowness, weakness, exhaustion, weight loss, and low activity) based on the criteria of the Japanese version of the Cardiovascular Health Study (J-CHS), was also assessed as a predictor of future falls and FOF. RESULTS: Multivariable logistic regression showed that prefrailty or frailty increase the risk of not only future falls (odds ratio [OR]: 1.57; 95% CI = 1.20-2.05) but also FOF (OR: 1.33; 95%CI = 1.05-1.69). In addition, the relationship between baseline frailty status and future falls remained significant after adjusting for baseline FOF (OR: 1.55; 95% CI = 1.19-2.02), and the relationship between baseline frailty status and future FOF also remained significant after adjusting for baseline falls (OR: 1.32; 95% CI = 1.04-1.68). CONCLUSIONS: Frailty status may predict future falls and FOF among community-dwelling older adults. Strategies to prevent frailty may be beneficial to prevent not only future falls but also future FOF in a community setting. IMPACT: Falls and FOF have a close relationship but a different clinical meaning. Older adults with physical frailty may require monitoring as high risk not only for falls but also for FOF.

    Oral hypofunction is a new concept that addresses the oral function of older adults. Few studies have investigated the relationship between oral hypofunction and general health conditions such as frailty, sarcopenia, and mild cognitive impairment. This paper explores these relationships in a large-scale, cross-sectional cohort study. The relationships of oral hypofunction with frailty, sarcopenia, and mild cognitive impairment were examined using data from 832 individuals who participated in the 2018 health survey of the residents of Tarumizu City, Kagoshima Prefecture, Japan. Individuals with frailty, sarcopenia, and mild cognitive impairment had significantly higher rates of oral hypofunction. Frailty was independently associated with deterioration of the swallowing function (odds ratio 2.56; 95% confidence interval, 1.26-5.20), and mild cognitive impairment was independently associated with reduced occlusal force (odds ratio 1.48; 95% confidence interval, 1.05-2.08) and decreased tongue pressure (odds ratio 1.77; 95% confidence interval, 1.28-2.43). There was no independent association found between sarcopenia and oral function. In conclusion, early intervention for related factors such as deterioration of the swallowing function in frailty, reduced occlusal force, and decreased tongue pressure in mild cognitive impairment could lead to the prevention of general hypofunction in older adults.

    Introduction: A prevalence of frailty is gradually increasing with the progress of aging in Japan, and critical challenges regarding early diagnosis and prevention of frailty were necessary in community. Although previous studies have well documented the characteristics of physical disability, there is limited information on frail state differences among older adults in Japanese rural areas. The aim of our cross-sectional observational study was to clarify the association of frail status in northern Japanese community-dwellers aged 65 or more. Methods: 345 participants were recruited from 2018 to 2020, and after getting informed consent from each participant, assessments and outcomes were evaluated according to the ORANGE protocol. We applied the frailty index of Gerontology-the Study of Geriatric Syndromes (NCGG-SGS) to classify frailty status by collecting data of demographics and psychosocial status using the Kihon checklist (KCL) and cognitive domains used by the National Center for Geriatrics and Gerontology-Functional Assessment Tool (NCGG-FAT). Results: Our subjects included 313 older adults divided into 138 robust, 163 prefrail, and 12 frail. For statistical analysis, we found that the frail group had a lower educational duration, worsened KCL items, lower cognitive functions, and a tendency toward depression compared to the other groups. Moreover, physical frailty and cognitive decline were related, and polypharmacy and a lack of joy in daily life were explanatory variables of frail status. Conclusions: We suggest that KCL is important for frail discrimination, and in order to prevent physical frailty, our community should take care of not only exercise and nutrition but also cognitive functioning and depressive tendencies. In particular, polypharmacy and the presence of fun in your life are possible to be related to frailty.

    Blood pressure (BP) is influenced by various factors, and it is known that temperature and BP have a negative relationship. However, few reports have examined the relationship between BP and temperature throughout the day in the same participant over time. Therefore, this study aimed to investigate the relationship between BP and temperature in the morning and evening in the same participants during a time period of ~1 year. In total, 401 participants, who participated in a community-based health checkup survey in Tarumizu, Japan, were enrolled. Five participants were excluded due to missing data. All participants measured their BP and the room temperature at home using a blood pressure monitor (HEM-9700T, OMRON Healthcare, Kyoto, Japan). The mean systolic BP (SBP) and diastolic BP (DBP) in the morning were significantly higher than the mean of the measurements taken in the evening (SBP: morning vs. evening 128 ± 15 mmHg vs. 122 ± 14 mmHg, P < 0.0001; DBP: morning vs. evening 77 ± 10 mmHg vs. 72 ± 8 mmHg, P < 0.0001). Using a linear mixed model with participants as a random effect, SBP and DBP were significantly associated with temperature in both the morning and evening. In the morning, in almost every month except July, a significant association between SBP and temperature was observed. However, there was a significant relationship between evening BP and temperature in all months. In conclusion, BP was significantly related to temperature in both the morning and evening during the year-long study. Furthermore, BP and temperature were significantly associated in all months except morning measurements in July.

    Aim: Olfactory impairment as a prodromal symptom, as well as sarcopenia, frailty and dependence as geriatric syndromes, is often associated with cognitive decline in older adults with progression of Alzheimer's disease. The present study aimed to evaluate the associations of olfactory and cognitive decline with these geriatric syndromes, and with structural changes of the brain in older adults.Methods: The participants were 135 older adults (47 men and 88 women, mean age 79.5 years), consisting of 64 with normal cognition, 23 with mild cognitive impairment and 48 with Alzheimer's disease. Olfactory function was evaluated by the Open Essence odor identification test. Shrinkage of the regional brain was determined by magnetic resonance imaging.Results: Logistic regression analysis with Open Essence, Mini-Mental State Examination, age and sex as covariates showed higher olfactory-cognitive index (|coefficient for Open Essence (a) / coefficient for Mini-Mental State Examination (b)|) in participants with sarcopenia (Asia Working Group for Sarcopenia), and lower values of (|a/b|) in participants with Barthel Index dependence, Kihon Checklist frailty, Lawton Index dependence and support/care-need certification as objective variables. Logistic regression analysis adjusted by age and sex also showed significant shrinkage of the frontal lobe in participants with AWGS sarcopenia, especially in women, and shrinkage of the medial temporal areas and global brain in participants with Kihon Checklist frailty/dependence.Conclusions: Olfactory-cognitive index (|a/b|) might be a useful tool to distinguish involvement of frontal lobe shrinkage, as in sarcopenia from shrinkage of the medial temporal areas, and global brain, as in frailty/dependence, in older adults with progression of normal cognition to Alzheimer's disease.

    Objective Older adults in Japan are tackling health-related challenges brought by comprehensive geriatric symptoms, such as physical and cognitive problems and social-psychological issues. In this nationwide study, we mainly focused on the Kihon checklist (KCL) as certificated necessity of long-term care for Japanese older adults and investigated whether the KCL score was associated with geriatric depression. In addition, we aimed to identify critical factors that influence the relationship between the KCL score and geriatric depression. Methods This survey was a cross-sectional observational study design, performed from 2013 to 2019. A total of 8, 760 participants aged 65 years and over were recruited from five cohorts in Japan, consisting of 6, 755 persons in Chubu, 1, 328 in Kanto, 481 in Kyushu, 49 in Shikoku and 147 in Tohoku. After obtaining informed consent from each participant, assessments were conducted, and outcomes were evaluated according to the ORANGE protocol. We collected data on demographics, KCL, physical, cognitive and mental evaluations. To clarify the relationship between the KCL and geriatric depression or critical factors, a random intercept model of multi-level models was estimated using individual and provincial variables depending on five cohorts. Results The KCL score was correlated with depression status. Moreover, the results of a random intercept model showed that the KCL score and geriatric depression were associated, and its association was affected by provincial factors of slow walking speed, polypharmacy and sex difference. Conclusions These results suggest that provincial factors of low walking performance, polypharmacy and sex difference (female) might be clinically targeted to improve the KCL score in older adults.

    <p>[Purpose] This study examined the changes in physical activity (PA) levels before and during the COVID-19 outbreak of older Japanese community-dwelling adults participating in exercise programs. [Participants and Methods] This observational study recruited 15 older adults. Participants were required to continuously wear an accelerometer on an elastic band on their hips for a week. Average daily duration of light, moderate, and total PA (min/day), as well as daily steps were calculated. Life-space assessment (LSA) scores were also assessed using a questionnaire. [Results] Although all participants reached 5 levels (from home to out of town) before the COVID-19 state of emergency declaration, 20% of them did not reach 5 levels during the state of emergency. Thus, there were no significant changes in any of the physical activity parameters and LSA before and during the declaration of emergency. [Conclusion] This study concludes that there was no significant decrease in physical activity levels among older community-dwelling adults participating in exercise programs before the COVID-19 outbreak in April 2020.</p>

    We examined the association between nutrient intake and prefrailty. Data from 815 older people (63% women) who participated in a community-based health check survey (Tarumizu Study) were analyzed. Prefrailty were defined using five parameters (exhaustion, slowness, weakness, low physical activity, and weight loss). Participants with one or more components were considered to belong to the prefrailty group. Nutrition intake was estimated from a validated brief-type self-administered diet history questionnaire. Among the participants, 154 men (52%) and 278 women (54%) were found to be in a status of prefrailty. In men, there were no significant associations between nutrient intake and prefrailty. In women, carbohydrate intake was slightly higher in prefrailty group. Vitamins K, B1, B2, folic acid, pantothenic acid, phosphorus, potassium, calcium, magnesium, iron, zinc, and copper intake was significantly lower in the prefrailty group. Among the nutrients, magnesium was identified as a significant covariate of prefrailty using a stepwise regression method. In women adjusted ORs (95%CI, p value) for prefrailty in the first, second, third, and fourth quartiles of magnesium intake were 1.00 (reference), 0.52 (0.29-0.92, 0.024), 0.51 (0.28-0.95, 0.033), and 0.38 (0.19-0.74, 0.005), respectively, by multivariate logistic regression analysis (variates: age, body mass index, energy intake, supplement use, osteoporosis, magnesium, and protein intake). Protein intake did not related to prefrailty. Protein intake might be sufficient to prevent prefrailty in the present study. We propose magnesium to be an important micronutrient that prevents prefrailty in community-dwelling older Japanese women.

    OBJECTIVES: This cross-sectional study aimed to clarify the relationship between apathy, meaningful activities, and satisfaction with such activities of older adults with mild cognitive impairment (MCI). METHODS: We analyzed 235 older adults with MCI (≥65 years, mean age: 76.9 ± 6.4 years, women: 63.4%) who participated in a community-based health check survey (Tarumizu Study 2018). MCI was defined as at least 1.5 SD below the reference threshold (age- and education-adjusted score) on one or more of the computerized cognitive test including memory, attention, executive functions, and processing speed. Apathy symptoms were assessed using three of the 15 items of Geriatric Depression Scale. Participants selected meaningful activities from the 95 activities of the Aid for Decision-Making in Occupation Choice and evaluated their satisfaction and performance. RESULTS: Apathy in MCI was prevalent by 23.8%. The categories of meaningful activities revealed no difference, with, or without apathy. Logistic regression analysis showed that activity satisfaction was significantly associated with apathy after adjusting for age, sex, education, instrumental activities of daily living, depressive symptoms, and MCI subtype (OR, 0.62; 95% CI, 0.44-0.88, p = 0.008). CONCLUSIONS: Satisfaction with the activities that are deemed meaningful is associated with apathy among community-dwelling older adults with MCI.

    OBJECTIVES: Diabetes and prediabetes contribute to an increased risk of cognitive decline and dementia. Currently, it remains unclear whether elevated blood HbA1c levels, including prediabetes levels, affect reversion from mild cognitive impairment (MCI) to normal cognition. This study, therefore, aimed to examine the prospective associations of diabetes and prediabetes with reversion from MCI to normal cognition among community-dwelling older adults. DESIGN: Longitudinal cohort study with a 4-year follow-up. SETTING AND PARTICIPANTS: Community-dwelling older adults with MCI, aged ≥65 years at baseline (n = 787). METHODS: Participants' medical history of diabetes and blood HbA1c levels at baseline were assessed, and they were classified as control, prediabetes, and diabetes. Objective cognitive screening was performed using a multicomponent neurocognitive test at baseline and follow-up. Reversion from MCI to normal cognition over 4 years was determined. In the longitudinal analysis, we performed multiple imputations to adjust for a selection bias and loss of information. RESULTS: The reversion rates of MCI in the control, prediabetes, and diabetes groups were 63.4%, 55.6%, and 42.9%, respectively, in the completed follow-up dataset, and 54.6%, 47.2%, and 34.1%, respectively, in the imputed dataset. Multivariate logistic regression showed that diabetes decreases the probability of MCI reversion both before and after multiple imputations [odds ratio (OR) 0.37; 95% confidence interval (CI) 0.18-0.74 for before imputation, OR 0.37; 95% CI 0.19-0.72 for after imputation]. Furthermore, prediabetes also showed significantly decreased probabilities of MCI reversion both before and after multiple imputations (OR 0.57; 95% CI 0.34-0.94 for before imputation, OR 0.60; 95% CI 0.37-0.97 for after imputation). CONCLUSIONS AND IMPLICATIONS: Diabetes and prediabetes could inhibit MCI reversion. Adequate glycemic control may be effective in enhancing the reversion from MCI to normal cognition in a community setting.

    The aim of this cross-sectional study was to examine the association between diet variety and physical frailty in community-dwelling older adults. Data of 577 older adults (mean age: 74.0 ± 6.3 years, women: 62.5%) were analyzed. Diet variety was assessed using the Food Frequency Score (FFS) (maximum, 30 points). The FFS assessed the one-week consumption frequency of ten foods (meat, fish/shellfish, eggs, milk & dairy products, soybean products, green & yellow vegetables, potatoes, fruits, seafood, and fats & oil). Physical frailty was assessed using Fried's component (slowness, weakness, exhaustion, low physical activity, and weight loss). The participants were classified into frail, pre-frail, and non-frail groups. The prevalence of physical frailty was 6.6%. This study found significant associations between physical frailty and low FFS after adjusting for covariates (odds ratio (OR) 0.90, 95% confidence interval (CI) 0.84-0.97, p < 0.01). The optimal cutoff point of the FFS for physical frailty was ≤16 points. FFS lower than the cutoff point were significantly associated with physical frailty after adjusting for covariates (OR 3.46, 95% CI 1.60-7.50, p < 0.01). Diet variety assessed using the FFS cutoff value of ≤16 points was related to the physical frailty status in community-dwelling older adults.

    INTRODUCTION: Frailty is associated with adverse outcomes, but few studies have determined associations between the frailty phenotype and measures of healthcare burden, including long-term care insurance (LTCI) costs, in older community-dwelling populations. OBJECTIVE: The aim of this study was to examine the association between frailty status and subsequent LTCI costs in Japanese community-dwelling older adults. METHODS: The prospective data were from a cohort study (National Center for Geriatrics and Gerontology-Study of Geriatric Syndromes [NCGG-SGS]). The participants were community-dwelling older adults (mean age 71.8 years, women 50.7%) participating in an NCGG-SGS baseline examination held between August 2011 and February 2012 in Obu, Japan (N = 4,539). At baseline, we assessed the physical frailty phenotype using the Japanese version of the CHS criteria and categorized it as robust, pre-frail, or frail. We also ascertained care-needs certification and total costs using long-term care services in Japan's public LTCI system during the 29 months. RESULTS: During the 29-month follow-up period, 239 participants (5.3%) required the LTCI system's care-needs certification and 163 participants (3.6%) used LTCI services. Participants classified as frail (odds ratio 5.85, 95% confidence interval 3.54-9.66) or pre-frail (2.40, 1.58-3.66) at the baseline assessment had an increased risk of requiring care-needs certification compared with robust participants. The mean total costs for LTCI services during the 29 months were \6,434 ($63.1) for robust, \19,324 ($189.5) for pre-frail, and \147,718 ($1,448.2) for frail participants (1 US dollar = 102 Japanese yen in July 2014). There were significantly higher costs associated with advancing frailty status. Individual frailty components (slowness, weakness, exhaustion, low activity, and weight loss) were also associated with higher total costs for using LTCI services. DISCUSSION/CONCLUSION: Frail community-dwelling older adults had a higher risk of requiring the LTCI system's care-needs certification and the subsequent total LTCI costs.

    OBJECTIVE: To examine whether age-specific prevalence of frailty in Japan changed between 2012 and 2017. DESIGN: This study performed meta-analyses of data collected from 2012 to 2017 using the Integrated Longitudinal Studies on Aging in Japan (ILSA-J), a collection of representative Japanese cohort studies. SETTING: The ILSA-J studies were conducted on community-living older adults. PARTICIPANTS: ILSA-J studies were considered eligible for analysis if they assessed physical frailty status and presence of frailty in the sample. Seven studies were analyzed for 2012 (±1 year; n = 10312) and eight studies were analyzed for 2017 (±1 year; n = 7010). Five studies were analyzed for both 2012 and 2017. MEASUREMENTS: The study assessed the prevalence of frailty and frailty status according to 5 criteria: slowness, weakness, low activity, exhaustion, and weight loss. RESULTS: The overall prevalence of physical frailty was 7.0% in 2012 and 5.3% in 2017. The prevalence of frailty, especially in people 70 years and older, tended to decrease in 2017 compared to 2012. Slight decreases were found in the prevalence of frailty subitems including weight loss, slowness, exhaustion, and low activity between 2012 and 2017, but change in the prevalence of weakness was weaker than other components. CONCLUSIONS: The prevalence of physical frailty decreased from 2012 to 2017. There are age- and gender-related variations in the decrease of each component of frailty.

    <p> 日常生活において,運動によって身体活動を促進することは,全世代を通して心身に効果的であることはおそらく疑いの余地はないであろう。身体活動の減少は,喫煙,高血圧に次いで日本人の死亡に及ぼす危険因子とされており,さまざまな疾患の発症リスクを増大させる(Ikeda N, <i>et al</i>. 2011)。とくに,高齢期の日常生活における身体活動(physical activity)を促進することは,健康寿命の延伸を目指すうえでの重要な課題のひとつと考える。</p><p> 習慣的な運動や積極的な身体活動は,認知症の発症リスクを低減させることにも寄与するとされている。週3回以上の運動習慣(15分以上の運動:ウォーキング,ハイキング,サイクリング,スイミング,水中運動,有酸素運動や柔軟体操,筋力トレーニングやストレッチングなど)を有する者では,週3回未満の者に比べて認知症を発症する危険が約38%低かったことが報告されている(Larson EB, <i>et al</i>. 2006)。さらに,運動習慣が認知症の発症に及ぼす影響は,軽度から中等度の運動機能の低下を認めた高齢者ほど顕著であった。つまり,やや運動機能の低下が生じ始めた時期に,より意識的に身体活動を維持・向上しておくことの重要性を示している。また,日常的な運動習慣は,加齢による脳萎縮の抑制に対しても効果的であることが期待されている(Cabral DF, <i>et al</i>. 2019)。</p><p> しかしながら,身体的活動を増加させるほどに望ましいかについては慎重になるべきである。高齢女性16,741名を対象に1日の歩数と死亡発生との関連を縦断的に調べた報告によると,約7,500歩に達するまでは1日歩数の増加は死亡リスク低減と関連したが,1日10,000歩に達することの付加的な利得は認められなかった(Lee IM, <i>et al</i>. 2019)。</p><p> 一般的に健康的な心身機能を維持するためには週150分(1日30分,週5日間)程度の中強度程度(やや速歩き相当)の運動の実施が推奨されている(Nelson ME, 2007)。しかし,高齢者にとっては中強度以上の負荷を伴う運動はさまざまな障壁やリスクを抱えることも少なくない。低強度から中強度の運動による身体活動(週3回程度)であっても,将来の認知障害の発生が有意に低くなることが報告されており(Sofi F, <i>et al</i>. 2011),たとえ低強度から中強度程度の負荷の運動であっても習慣化することが高齢期の認知機能低下の予防に有効であるかもしれない。さらに,アルツハイマー病を発症する9~10年程度前から身体活動量が低下し始めるとされている(Sabia S, <i>et al</i>. 2017)。そのため,一時的に運動習慣を習得して身体活動量を高めるだけではなく,高めた身体活動量を維持する生活スタイルをいかにして確立するかがさらに重要である。</p><p> 日常におけるさまざまな活動には,身体的活動(physical activity)の他,知的活動(cognitive activity),社会的活動(social activity)などがあり,これらが高齢期における健康関連指標へ影響を及ぼすことが示唆されている。日常でこれらの活動をいかに多面的に促進していくかが健康長寿の鍵になると考えられ,理学療法には対象者の活動の多様性と継続性を支援することも重要な対策のひとつと考えられる。</p>

    (1) Background: The present study aimed to examine physical, cognitive and emotional factors affecting falls in community-dwelling older adults with and without pain; (2) Methods: Data from 789 older adults who participated in a community-based health survey were analyzed. Participants completed questionnaires on the presence of pain and previous falls. Muscle weakness (handgrip strength &lt; 26.0 kg for men and &lt; 18.0 kg for women) and low skeletal muscle mass (appendicular skeletal muscle mass index &lt; 7.0 kg/m2 for men and &lt; 5.7 kg/m2 for women) were determined. Mild cognitive impairment (MCI) and depressive symptoms were assessed using the National Center for Geriatrics and Gerontology-Functional Assessment Tool and 15-item geriatric depression scale (GDS-15), respectively; (3) Results: In participants with pain, MCI and GDS-15 were associated with previous falls after adjusting for age, sex, education and medication use. In participants without pain, muscle weakness and low skeletal muscle mass were associated with previous falls when adjusting for the above covariates; (4) Conclusions: Falls in participants with pain were associated with cognitive and emotional factors, whereas falls in those without pain were associated with physical factors. Fall prevention interventions for older adults with pain may require tailored strategies to address cognitive and emotional factors.

    The aim of this cross-sectional study was to investigate relationships between individuals' ratings of satisfaction and performance of activities that they found meaningful and depressive symptoms. Data was obtained from 806 older adults (mean age 74.9 ± 6.3 years, women = 63.0%) who participated in a community-based health check survey (Tarumizu Study 2018). Participants selected meaningful activities from 95 activities using the Aid for Decision-Making in Occupation Choice and evaluated their satisfaction and performance. Depressive symptoms were assessed using the 15-item Geriatric Depression Scale (GDS-15) and defined by a GDS-15 score of ≥5. Non-linear logistic regression analyses were used separately by gender to examine the association between satisfaction and performance of meaningful activities and depressive symptoms. The prevalence of depressive symptoms was 15.8%. We found no significant difference between meaningful activity choice between older adults with depressive symptoms and those without, in both men and women. After adjusting for potential covariates, satisfaction was associated with depressive symptoms in both men (OR 0.52, 95% CI 0.35-0.77) and women (OR 0.67, 95% CI 0.49-0.91), but performance was limited in women (OR 0.87, 95% CI 0.77-0.99). Our findings suggest that depressive symptoms are associated with satisfaction in meaningful activities regardless of activity categories.

    OBJECTIVES: The current study aimed to elucidate the associations between cognitive leisure activities and cognitive function in an older population stratified by having or not having depressive symptoms. DESIGN: A retrospective cross-sectional study based on a self-report questionnaire. SETTING: Annual health check-ups in a rural community in Japan. PARTICIPANTS: A total of 11 010 community-dwelling older adults aged ≥65 years (mean age: 74.0±5.4 years) was examined. Participants with missing data for the main outcome (n=1630) were excluded. OUTCOME MEASURES: Cognitive impairment was defined as at least 1.5 SD below the reference threshold (age-adjusted and education-adjusted score) on two of more of the tests in the National Center for Geriatrics and Gerontology-Functional Assessment Tool. Depressive symptoms were defined by a 15-item Geriatric Depression Scale score ≥6. We assessed the frequency of participation in cognitive leisure activities using the validated scale (score: 0-42). A score of ≥8 points was defined as frequent participation in cognitive leisure activities. RESULTS: A total of 12.6% (n=1186) of the participants had depressive symptoms. There was a significant association between cognitive leisure activities and cognitive impairment in older adults (adjusted OR=0.77, 95% CI=0.65 to 0.94). In older adults with depressive symptoms, a higher frequency of cognitive leisure activities was negatively associated with cognitive impairment (adjusted OR=0.45, 95% CI=0.28 to 0.70). In contrast, there was no significant association in older adults without depressive symptoms (adjusted OR=0.85, 95% CI=0.70 to 1.02). CONCLUSIONS: Engaging in cognitive leisure activities in late life is associated with better cognitive function in older adults with depressive symptoms.

    Depressive symptoms and memory problems are risk factors for dementia. Exercise can reduce these in older people, and horticultural activity can benefit people with dementia. This study assessed the efficacy of exercise and horticultural interventions for community-dwelling older adults with depressive symptoms and mild memory decline. In this randomized controlled trial, older adults (n = 89) were assigned to exercise, horticultural, or control groups. Exercise and horticultural programs included 20 weekly 90-minute sessions. The control group attended two 90-minute classes. Outcomes were assessed at baseline, and then 6- and 12-months post-intervention. Primary outcome measures were the Geriatric Depression Scale-15 (GDS-15) and Wechsler Memory Scale-Revised. Walking speed, two-minute walking test scores, social network, life space, and subjective daily physical activity were secondary outcome measures. Compared with the control group, the exercise group obtained higher immediate and delayed recall logical memory scores, and the increase in immediate recall scores remained 12-months post-intervention. Two-minute walking performance improved in the exercise group, but not after 12 months. GDS-15 scores showed no significant improvements. The horticultural and control groups showed no differences. Exercise may improve memory, while horticultural activity may not. The effects of exercise and horticultural interventions on depressive symptoms remain unclear.

    A gradually increasing prevalence of mild cognitive impairment (MCI) is recognized in the super-aging society that Japan faces, and early detection and intervention in community-dwellers with MCI are critical issues to prevent dementia. Although many previous studies have revealed MCI/non-MCI differences in older individuals, information on the prevalence and characteristics of MCI in rural older adults is limited. The aim of this study was to investigate differential characteristics between older adults with and without MCI. The investigation was conducted over one year from 2018 to 2019. Participants were recruited from Akita in northern Japan. Neuropsychological assessments were applied to classify MCI, including the National Center for Geriatrics and Gerontology Functional Assessment Tool (NCGG-FAT) and the Touch panel-type Dementia Assessment Scale (TDAS) based on the Alzheimer's disease assessment scale. Our samples consisted of 103 older adults divided into 54 non-MCI and 49 MCI. The MCI group had lower scores of all cognitive items. Our results showed that individuals with MCI had significantly slower walking speed (WS) and worse geriatric depression scale (GDS) compared to non-MCI. In addition, WS was significantly associated with some cognitive items in non-MCI, but not in MCI. Finally, we showed that predictive variables of MCI were WS and GDS. Our study provides important information about MCI in rural community-dwellers. We suggest that older adults living in a super-aging society should receive lower limb training, and avoiding depression in older adults through interaction of community-dwellers may contribute to preventing the onset of MCI.

    AIM: The present study aimed to determine whether measures of chronic pain are associated with social frailty in community-dwelling older adults. METHODS: Participants comprised 248 older adults who enrolled for community-based exercise classes. Chronic pain was defined as the presence of significant pain-related symptoms within the past month that had continued for at least 6 months. Social frailty was defined as positive responses to two of the following five questions (going out less frequently, rarely visiting friends, feeling unhelpful to friends or family, living alone and not talking with someone every day). Physical function was assessed using the Chair Stand and Timed Up and Go tests. RESULTS: A total of 55 participants (22.2%) met the criteria for social frailty. A total of 28 socially frail participants (50.9%) and 56 of the socially integrated participants (29.0%) reported chronic pain. The presence of chronic pain was significantly associated with social frailty after adjusting for age, sex and physical function measures (odds ratio 2.13, 95% confidence interval 1.01-4.48). Chronic pain was also significantly associated with three social frailty items: going out less frequently, rarely visiting friends and feeling unhelpful to friends or family. CONCLUSIONS: Chronic pain was independently associated with social frailty in community-dwelling older adults. Simple assessments of chronic pain and subsequent pain management interventions might be beneficial for older people with social frailty. Geriatr Gerontol Int 2019; 19: 1153-1156.

    AIM: This cross-sectional study examined whether sleep duration and excessive daytime sleepiness (EDS) were associated with social frailty in community-dwelling older people. METHODS: A total of 4427 community-dwelling older people (51.4% women, mean age 71.9 years) who met the entry criteria were included in this study. Social frailty was assessed by five questions, relating to going out less frequently than last year, not visiting friends sometimes, not feeling helpful to friends or family, living alone and not talking with someone every day. Participants with two or more components were defined as having social frailty. Sleep duration and EDS were assessed by self-reported questionnaire. Logistic regression analysis estimated odds ratios and 95% confidence intervals of social frailty according to EDS or the three categories of sleep duration (short ≤6.0 h, medium 6.1-8.9 h, long ≥9.0 h), and we used medium-duration sleepers as the reference group. RESULTS: Among all participants, the prevalence of social frailty in each sleep duration group was as follows: long 18.3%, short 9.9% and medium 9.7% (P < 0.001). The prevalence of social frailty in participants with EDS was 17.1% (no EDS 10.2%, P < 0.001). Long sleep duration (odds ratio 1.46, 95% confidence interval 1.14-1.84) and presence of EDS (hazard ratio 1.32, 95% confidence interval 1.02-1.71) were associated with higher rates of social frailty after adjustments for several covariates. CONCLUSIONS: Long sleep duration and EDS were associated with social frailty; thus, older people with both sleep patterns would have a higher risk of progression of social frailty.

    This study examined whether sleep duration and excessive daytime sleepiness (EDS) are related to cognitive decline among community-dwelling older adults with intact cognition at baseline, using 4-year longitudinal data. A total of 3,151 community-dwelling older individuals aged ≥65 years were studied. They were assessed for cognitive function, including memory, attention, executive function and processing speed. Cognitive impairment was defined based on a score >1.5 standard deviations below the age- and education-specific mean. Cognitive decline was defined in one or more cognitive tests at follow-up. Self-reported sleep duration (short, ≤6.0 hr; medium, 6.1-8.9 hr; long, ≥9.0 hr) and EDS at first-wave examination were assessed and logistic regression analyses were used to examine the associations of sleep duration and EDS with cognitive status at second-wave examination. The incidence of cognitive decline differed significantly among the sleep-duration groups (short, 15.9%; medium, 11.9%; long, 20.1%; p = 0.001). The prevalence of having EDS was 13.1%, which was associated with a higher rate of cognitive decline than having no EDS (18.9% vs. 12.5%, p = 0.004). Long sleep duration compared with medium sleep duration (OR, 1.50; 95% CI, 1.05-2.13) and EDS (1.43; 1.01-2.03) independently impacted the incidence of cognitive decline. The results were similar after multiple imputations (long, 1.68, 1.12-2.52; EDS, 1.55, 1.05-2.29). In conclusion, our study revealed that both long sleep duration and EDS were independent risk factors associated with cognitive decline after 4 years among older adults.

    This cross-sectional study investigated the association between chronic pain and physical frailty in community-dwelling older adults. We analyzed data obtained from 323 older adults (women: 74.6%) who participated in a community-based health check survey (the Tarumizu Study, 2017). Physical frailty was defined in terms of five parameters (exhaustion, slowness, weakness, low physical activity, and weight loss). We assessed the prevalence of chronic low back and knee pain using questionnaires. Participants whose pain had lasted ≥two months were considered to have chronic pain. Among all participants, 138 (42.7%) had chronic pain, and 171 (53.0%) were categorized as having physical frailty or pre-frailty. Logistic regression analysis showed that chronic pain was significantly associated with the group combining frailty and pre-frailty (odds ratio 1.68, 95% confidence interval 1.03-2.76, p = 0.040) after adjustment for age, sex, body mass index, score on the 15-item Geriatric Depression Scale, and medications. Comparing the proportions of chronic pain among participants who responded to the sub-items, exhaustion (yes: 65.9%, no: 39.4%) demonstrated a significant association (p < 0.001). Chronic pain could be associated with the group combining frailty and pre-frailty and is particularly associated with exhaustion in community-dwelling older adults. Therefore, there is a need for early intervention and consideration of the role of exhaustion when devising interventions for physical frailty in older individuals with chronic pain.

    Outpatient rehabilitation (OR) and outpatient day long-term care (ODLC) services are frequently used by older adult patients in Japan. However, there is a need to clarify that OR service, which has more rehabilitation professionals than ODLC, has the role of providing rehabilitation. This retrospective study examined the impact of OR services by comparing the two services based on City A data from the care-needs certification survey conducted between 2015 to 2017. We performed a propensity score matched analysis to compare the changes in the care level and function of OR and ODLC users after two years. The results showed that OR users showed a lower deterioration in care levels and less decline in the activities of daily living (ADL) in dementia and adaptation to social life. In the analysis of older adults requiring support, OR users had a lower deterioration in care levels and less decline in the ADL in dementia and behavioral and psychological symptoms than ODLC users did. There was no difference between the two services with respect to older adults requiring long-term care. The OR service has had an increasingly preventive effect on the deterioration of care levels compared to the ODLC service, which was particularly evident in older adults requiring support.

    This cross-sectional study investigated the association between osteoporosis, grip strength, and skeletal muscle mass in community-dwelling older women. Data obtained from 265 older women who participated in a community-based health check survey (Tarumizu Study) were analyzed. Face-to-face interviews with participants revealed their history of osteoporosis. Appendicular skeletal muscle mass was assessed through bioelectrical impedance analysis, and appendicular skeletal muscle index was calculated. Dominant grip strength was also assessed. Loss of skeletal muscle mass (appendicular skeletal muscle mass < 5.7 kg/m²) and muscle weakness (grip strength < 18 kg) were determined based on criteria for sarcopenia put forth by the Asian Working Group for Sarcopenia. The prevalence rates of osteoporosis, muscle weakness, and loss of skeletal muscle mass were 27.2%, 28.7%, and 50.2%, respectively. Loss of skeletal muscle mass was more prevalent in participants with osteoporosis than in those without (65.3% vs. 44.6%, p < 0.01). The association between osteoporosis and muscle strength was not significant (30.6% vs. 28.0%, p = 0.68). After covariate adjustment, loss of skeletal muscle mass was found to be independently associated with osteoporosis (odds ratio 2.56, 95% confidence interval 1.33⁻4.91). In sum, osteoporosis was found to be associated with loss of skeletal muscle mass, but not with muscle weakness in community-dwelling older women.

    This study examined the association between the estimated glomerular filtration rate (eGFR) and disability incidence according to sedentary time in community-dwelling Japanese older adults. This prospective cohort study sampled 5,104 community-dwelling older adults (≥65 years) enrolled in a health promotion study in a general population. The participants (n = 4,457; ≥65 years) were monitored for inclusion in the long-term care insurance system for 4 years. This study used blood samples to assess eGFR. Cox proportional regression analysis was used to determine predictors of disability. In total, 461 participants (10.3%) became newly certified as needing long-term care insurance services. Cox regression models were adjusted for multiple confounders: eGFR < 45 ml/min/1.73 m2 (hazard ratio = 1.741, 95% confidence interval [1.193-2.539]) and eGFR < 45 ml/min/1.73 m2 with high sedentary time (≥8 hr) (hazard ratio = 4.367, 95% confidence interval [2.021-9.438]) remained significantly associated with disability incidence. Our findings suggest that in the case of chronic kidney disease, the disability incidence rate may be affected by sedentary time.

    BACKGROUND: Although previous studies have revealed many factors related to mild cognitive impairment (MCI) reversion, information about reversible factors related MCI reversion is limited, impeding the development of intervention strategies. The aim of the present study was to examine whether reversible factors such as lifestyle activities are associated with MCI reversion in elderly individuals using the National Center for Geriatrics and Gerontology-Study of Geriatric Syndromes database. A total of 396 community-living older adults (age ≥ 65 years) participated in the study. They were classified as reverters or non-reverters from mild cognitive impairment to normal cognition. We assessed lifestyle activities, potential confounding factors of cognitive decline, and reversion of mild cognitive impairment. RESULTS: In a completed data set of 396 participants, 202 participants (51.0%) reverted from MCI to normal cognition. The reversion rate in participants for whom we imputed data was 34.3%. In the imputed group, a logistic regression model showed that the odds ratios (ORs) for reversion were significantly higher in participants who drove a car (OR 1.50, 95% confidence interval (CI) 1.41-1.60), used a map to travel to unfamiliar places (OR 1.12, 95% CI 1.06-1.18), read books or newspapers (OR 1.54, 95% CI 1.37-1.73), took cultural classes (OR 1.10, 95% CI 1.04-1.15), attended meetings in the community (OR 1.22, 95% CI 1.16-1.28), participated in hobbies or sports activities (OR 1.09, 95% CI 1.03-1.16), and engaged in fieldwork or gardening (OR 1.14, 95% CI 1.08-1.21). The imputed sample showed that non-reverters were more likely to discontinue fieldwork or gardening (11.0% vs. 6.1%) than reverters during the follow-up period. CONCLUSIONS: Specific lifestyle activities may play important roles in MCI reversion in older adults. The longitudinal data indicate that it is reasonable to recommend that individuals continue to engage in fieldwork or gardening to increase their chance of recovery from MCI.

    BACKGROUND: Driving cessation is strongly associated with adverse health outcomes in the older adults. Although there were numerous documentations of driving rehabilitation in disabled adults, the effects of interventions on safe driving were not clear in older adults with cognitive impairment who had low driving skills. OBJECTIVE: This randomized controlled trial was designed to determine whether a safe driving skill program consisting of classroom and on-road training could enhance driving performance of older drivers with cognitive impairment in Japan. METHODS: A total of 160 community-living older drivers participated in the randomized controlled trial with blinded endpoint assessment. Participants randomized to intervention underwent 10 1-h classroom sessions and 10 1-h on-road sessions focused on common problem areas of older drivers. Controls received 1 classroom education. On-road driving performance was assessed by certified driving school instructors in a driving school. The participants carried out dynamic vision and cognitive performance tests. RESULTS: One hundred and forty-six (intervention group, n = 71) subjects completed the 3-month follow-up. Mean adherence to classroom-based vision training and driving simulator training and on-road training programs, including the 71 participants, was 99.0 ± 6.4 and 99.0 ± 7.2%, respectively. Regarding the safe driving skill score, there were group × time interactions (p < 0.01) indicating benefits of the intervention over time. Although there were no significant group × time interactions in cognitive tests, dynamic vision showed group × time interactions (p < 0.01). CONCLUSION: The driving skill program significantly improved safe driving performance in older adults with cognitive impairment who were at a potentially high risk of a car accident.

    The aim of this systematic review and meta-analyses was to calculate the pooled prevalence of sarcopenia based on the Asia Working Group for Sarcopenia (AWGS) criteria among Japanese community-dwelling older adults. Data from 8 studies were used to determine the prevalence of sarcopenia in the overall population and in men; data from 9 studies were used to determine that of women. The pooled prevalence rates of sarcopenia using random-effects models were 9.9% (95% confidence interval [CI], 6.2%-15.4%) overall; 9.8% (95% CI, 6.2%-15.2%) among men; and 10.1% (95% CI, 6.4%-15.5%) among women. These findings would be useful to inform community-based strategies and advanced research addressing sarcopenia prevention.

    AIM: The purpose of the present study was to identify risk factors for physical frailty and to understand the transitional status of frailty. METHODS: The participants were 4676 older adults in the National Center for Geriatrics and Gerontology - Study of Geriatric Syndromes. Physical frailty status was classified as robust, pre-frail and frail at baseline and 4-year follow up (mean follow up 47.9 ± 1.8 months). Data for demographic variables, medical conditions, fall, depressive symptoms and cognitive function were also collected. Multiple imputation was used to reduce selection bias and loss of information. RESULTS: Progression occurred from a robust to frail status in 52 participants (2.6%) and from pre-frailty to frailty in 281 participants (12.0%). Mortality increased with frailty status at baseline: robust 46 (2.3%), pre-frail 112 (4.8%) and frail 54 (15.6%). In logistic regression analysis, age (OR 1.10, 95% CI 1.06-1.13), sex (men; OR 0.67, 95% CI 0.46-0.95), body mass index (OR 1.06, 95% CI 1.01-1.12]), fall (OR 1.92, 95% CI 1.31-2.81), Geriatric Depression Scale (OR 1.15, 95% CI 1.08-1.22), Mini-Mental State Examination (OR 0.87, 95% CI 0.82-0.93) and education (OR 0.91, 95% CI 0.85-0.98), were related with new incident frailty. Among participants in the pre-frail class at baseline, exhaustion (OR 3.24, 95% CI 1.97-5.34), physical inactivity (OR 3.09, 95% CI 1.94-4.93), lower muscle strength (OR 3.77, 95% CI 2.35-6.03) and lower mobility (OR 2.54, 95% CI 1.57-4.10) were related to progression to frailty (all P < 0.05). CONCLUSIONS: The results of the present prospective study provide key information on the transitional status of frailty and the risk factors for progression to frailty. A further study is required to determine the pathophysiological changes that underlie the transition to frailty. Geriatr Gerontol Int 2018; 18: 1562-1566.

    BACKGROUND: Anorexia of ageing may be a precursor to various geriatric syndromes. We elucidated whether anorexia of ageing had a significant impact on incident disability and investigated whether anorexia of ageing had a direct association with future disability or an indirect association with disability via frailty. METHODS: This study employed an observational, longitudinal, cohort design in a community setting. Participants were 4393 older adults (75.9 ± 4.3 years). Anorexia of ageing was assessed by a simplified nutritional appetite questionnaire. Frailty was operationalized as slowness, weakness, exhaustion, low physical activity, and weight loss. Participants who had none of these characteristics were considered robust, those with one or two characteristics were considered pre-frail, and those with three or more characteristics were considered frail. We examined sociodemographic variables (age, sex, and education), medical history (medication and chronic disease history), lifestyle factors (smoking and drinking habits and living arrangement), body mass index, blood nutrition data, depressive symptoms, physical functioning, and cognitive functioning. RESULTS: The prevalence of anorexia of ageing was 10.7% (n = 468). The proportion of physical frailty, pre-frailty, and robustness were 8.4, 52.0, and 39.6%, respectively, in the without anorexia of ageing group, and 20.3, 57.7, and 22.0%, respectively, in the anorexia of ageing group (P < 0.001). During a 2-year follow-up, the prevalence proportion of disability was 5.6% in the without anorexia of ageing group and 10.7% in the anorexia of ageing group (P < 0.001). Adjusted for covariates (except for frailty status), the participants with anorexia of ageing had an independently associated higher risk of incident disability compared with those without anorexia of ageing (hazard ratio: 1.43, 95% confidence interval: 1.04-1.95, P = 0.03). However, adjusted for covariates (including frailty status), anorexia of ageing was not significantly associated with incident disability (P = 0.09). Structural equation models revealed that anorexia of ageing had no direct effect on disability; however, anorexia of ageing was associated with frailty. CONCLUSIONS: Older adults with anorexia of ageing had a higher proportion of frailty and a higher prevalence proportion of disability compared with those without anorexia of ageing. Although anorexia of ageing may not have a direct effect on incident disability, the structural equation model suggests an indirect relationship between anorexia of ageing and incident disability via frailty status.

    BACKGROUND: Walk ratio (WR), calculated by dividing step length by cadence, can be used to represent the gait characteristics of human beings to maintain their gait speed. RESEARCH QUESTION: The aim of this study was to examine whether WR could distinguish fallers from community-dwelling elderly people. METHODS: We recruited 9205 elderly people (mean age: 73.7 ± 5.6 years, 4218 men and 4987 women) from the National Center for Geriatrics and Gerontology - Study of Geriatric Syndromes. Fall history was assessed by face-to-face interview, and "fallers" were defined as people who had fallen at least once within the past year. WR was calculated as corrected step length divided by corrected cadence, and we divided the subjects into three groups according to the tertile of WR (T1, T2, and T3). We also stratified the participants by gait speed (<1.0 or ≥1.0 m/s). RESULTS: With reference to the T3 group, the T1 group had a higher odds ratio (OR) of falling in the past year [OR: 1.24, 95% confidence interval (CI): 1.09-1.41], even after adjusting for other covariates. After stratification by gait speed, the same multivariate analyses were conducted. In the participants who walked at 1.0 m/s or faster, the T1 group had a higher OR [1.27, 95% confidence interval (CI): 1.10-1.48], while there was no significant association with fall rate among those who walked slower than 1.0 m/s. SIGNIFICANCE: This study revealed that the smallest WR was independently associated with falling in the past year among community-dwelling elderly people, especially elderly people with no deterioration of gait speed. These results suggest that intervention regarding gait pattern, especially WR, would help to prevent falls.

    AIM: The prevalence of dementia is rising due to increases in the aging population and chronic health conditions. The present study examined whether lifestyle activities, including instrumental activities of daily living and social roles, were associated with dementia incidence in Japanese community-dwelling older adults. METHODS: This longitudinal study involved 4564 participants (age ≥65 years) who were classified by age and sex. Lifestyle activities, risk factors for dementia and incidence of new dementia were recorded. RESULTS: After an average of 42.6 months, 219 participants (4.8%) experienced a new onset of dementia. Survival analyses using the Cox proportional hazards regression model showed that the probability of dementia was significantly lower in participants who engaged in daily conversation (hazard ratio [HR] 0.56, 95% confidence interval [CI] 0.35-0.89, P = 0.015), driving a car (HR 0.63, 95% CI 0.45-0.88, P = 0.007), shopping (HR 0.57, 95% CI 0.34-0.96, P = 0.033) and field work or gardening (HR 0.71, 95% CI 0.54-0.94, P = 0.016). CONCLUSIONS: We concluded that specific lifestyle activities might play an important role in preventing dementia in older adults. The activities that prevent dementia might differ depending on sex and age. Geriatr Gerontol Int 2018; 18: 1491-1496.

    BACKGROUND: Mild cognitive impairment (MCI) is a high risk of conversion to dementia and gait dysfunction is also a risk for dementia. The goal of the study was to examine if co-occurrence of MCI and slow gait (SG) increases the risk of dementia. METHODS: A prospective study was conducted in 3937 older adults who did not have dementia at baseline. Participants were classified into groups based on status of MCI and SG: without MCI and SG (control), without MCI and with SG (SG), without SG and with MCI in a single domain (sMCI) or multiple domains (mMCI), sMCI and SG (sMCI + SG), and mMCI and SG (mMCI + SG). Incident dementia was followed monthly. Cox proportional hazards regression models were used to calculate the hazard ratio for incident dementia in each group. RESULTS: During a mean follow-up period of 43 months, 182 subjects had incident dementia. MCI was a risk factor for dementia and SG increased the risk, even after adjusting for covariates (SG: HR = 1.31 (0.81-2.14), 95% CI = 0.276, sMCI: HR = 1.87, 95% CI = 1.21-2.88, p = .005; mMCI: HR = 3.36, 95% CI = 1.98-5.71, p < .001; sMCI + SG: HR = 3.33, 95% CI = 1.92-5.77, p < .001; mMCI + SG: HR = 5.02, 95% CI = 2.75-9.14, p < .001). CONCLUSIONS: Co-occurrence of MCI and SG has a high risk of dementia compared to that of each condition alone. Evaluation of both gait and cognition is useful in risk assessment of dementia.

    Cognitive frailty, defined as the presence of both frailty and cognitive impairment, is a risk factor for adverse events in older adults. However, prevalence rates of cognitive frailty are low (1.1⁻2.5%), so primary screening is unsuitable in community settings. The aim of the study was to examine whether a new definition of cognitive frailty, which was developed for primary screening, is useful to predict incident dementia in community-dwelling older adults. A total of 4570 older adults participated in the study (2326 women; average age, 71.9 ± 5.5 years). We defined physical frailty as the presence of ≥1 of the following symptoms: slow walking speed and muscle weakness. Cognitive impairment was defined as ≥1 symptom of cognitive impairment, indicated by an age- and education-adjusted score that was ≥1.5 standard deviations below the reference threshold in word list memory, attention, executive function, and processing speed tests. Cognitive frailty was defined as comorbid physical frailty and cognitive impairment. The incidence of dementia was determined using data collected by the Japanese Health Insurance System over 36 months. The prevalence rates of physical frailty, cognitive impairment, and cognitive frailty were 17.5%, 15.3%, and 9.8%, respectively. Cognitive impairment (hazard ratio [HR]: 2.06, 95% confidence interval [95% CI]: 1.41⁻3.02) and cognitive frailty (HR: 3.43, 95% CI: 2.37⁻4.97) were found to be significant risk factors for dementia. However, the association between dementia and physical frailty was not significant (HR: 1.13, 95% CI: 0.76⁻1.69). Individuals with comorbid physical frailty and cognitive impairment could have a higher risk of dementia than healthy older adults or older adults with either physical frailty or cognitive impairment alone.

    IMPORTANCE: Although participation in physical and cognitive activities is encouraged to reduce the risk of dementia, the preventive efficacy of these activities for patients with mild cognitive impairment is unestablished. OBJECTIVE: To compare the cognitive and mobility effects of a 40-week program of combined cognitive and physical activity with those of a health education program. DESIGN: A randomized, parallel, single-blind controlled trial. SETTING: A population-based study of participants recruited from Obu, a residential suburb of Nagoya, Japan. PARTICIPANTS: Between August 2011 and February 2012, we evaluated 945 adults 65 years or older with mild cognitive impairment, enrolled 308, and randomly assigned them to the combined activity group (n = 154) or the health education control group (n = 154). INTERVENTIONS: The combined activity program involved weekly 90-minute sessions for 40 weeks focused on physical and cognitive activities. The control group attended 90-minute health promotion classes thrice during the 40-week trial period. MEASUREMENT: The outcome measures were assessed at the study's beginning and end by personnel blinded to mild cognitive impairment subtype and group. The primary endpoints were postintervention changes in scores on (1) the Mini-Mental State Examination as a measure of general cognitive status and memory, (2) the Wechsler Memory Scale-Revised-Logical Memory II, and (3) the Rey Auditory Verbal Learning Test. We applied mobility assessments and assessed brain atrophy with magnetic resonance imaging. RESULTS: Compared with the control group, the combined activity group showed significantly greater scores on the Mini-Mental State Examination (difference = 0.8 points, P = .012) and Wechsler Memory Scale-Revised-Logical Memory II (difference = 1.0, P = .004), significant improvements in mobility and the nonmemory domains and reduced left medial temporal lobe atrophy in amnestic mild cognitive impairment (Z-score difference = -31.3, P < .05). CONCLUSION: Combined physical and cognitive activity improves or maintains cognitive and physical performance in older adults with mild cognitive impairment, especially the amnestic type.

    OBJECTIVES: Whether sarcopenia predicts incident homebound status remains unclear. This prospective cohort study aimed to determine the impact of sarcopenia on the incidence of homebound status in community-dwelling older adults. METHODS: The study included 3958 community-dwelling elderly people aged ≥65 years who were not homebound at baseline. Sarcopenia was defined as the presence of both poor muscle function (low physical performance or low muscle strength) and low muscle mass. Potential confounding factors, such as physical status, mental status, and level of social participation, were also assessed. Fifteen months after the baseline measurements, data regarding the incidence of homebound status were obtained using a postal survey. RESULTS: In the 15-month follow-up survey, 83 participants (2.1%, 95% confidence interval = 1.6-2.5) were reported to have become homebound. A multiple logistic regression analysis indicated that age (odds ratio = 1.06, 95% confidence interval = 1.02-1.10), sarcopenia (1.98, 1.04-3.77), and limited contact with friends (1.82, 1.03-3.23) were independently associated with an increased risk of becoming homebound. In a stratified analysis for age group, a significant odds ratio for low level of social role (2.50, 1.06-5.91) was observed in young-old subjects (aged 65-74 years), whereas significant odds ratios for sarcopenia (2.80, 1.33-5.91) and physical inactivity (2.85, 1.28-6.37) were observed in old-old subjects (aged 75 years and over). CONCLUSION: Sarcopenia had a strong impact on the risk of becoming homebound. Particularly in old-old subjects, sarcopenia and physical inactivity may impair people's ability to engage in activities outside the home much more than either their mental status or their level of social participation.

    AIM: To examine the relationship between cognitive function and unsafe driving acts among community-dwelling older adults with cognitive impairments. METHODS: Participants (n = 160) were older residents of Obu, Japan, aged ≥65 years with cognitive impairments. They regularly drove and were assessed for the number of unsafe driving acts without adequate verification during an on-road test. We also evaluated cognitive function (attention, executive function and processing speed). Other examined variables included demographics, driving characteristics and visual condition. RESULTS: Participants were classified into two groups according to the number of unsafe driving acts as follows: high group (≥4 unsafe driving acts) and low group (≤3 unsafe driving acts). The high group participants were older in age (P < 0.001) and obtained a lower score on the symbol digit substitution task (P = 0.002) than the low group. The number of unsafe driving acts showed modest significant positive correlations with age (r = 0.396, P < 0.001). The symbol digit substitution task score was significantly associated with the number of unsafe driving acts (β = -0.196, P < 0.05) after adjusting for age group. CONCLUSIONS: Processing speed was associated with unsafe driving acts that became worse with increasing age. Future study will be required to longitudinally examine the influence of processing speed on traffic accidents for those with cognitive impairments. Geriatr Gerontol Int 2018; 18: 847-852.

    OBJECTIVES: To examine the association between each type of frailty status and the incidence rate of depressive symptoms among community-dwelling older adults. DESIGN: Prospective cohort study. SETTING: General communities in Japan. PARTICIPANTS: Participants comprised 3538 older Japanese adults. MEASUREMENTS: We assessed our participants in terms of frailty status (physical frailty, cognitive impairment, and social frailty), depressive symptoms (geriatric depression scale ≥6), and other covariates, and excluded those who showed evidence of depression. Then, after a 4-year interval, we again assessed the participants for depressive symptoms. Physical frailty was defined by the Fried criteria, showing 1 or more of these were physical frailty. To screen for cognitive impairment, receiving a score below an age-education adjusted reference threshold in 1 or more tests was cognitive impairment. Finally, social frailty was defined using 5 questions, and those who answered positively to 1 or more of these were considered to have social frailty. RESULTS: After multiple imputations, the incidence rate of depressive symptoms after 4 years of follow-up was 7.2%. The incidence rates of depressive symptoms for each frailty status were as follows: 9.6% for physical frailty vs 4.6% without, 9.3% for cognitive impairment vs 6.5% without, and 12.0% for social frailty vs 5.1% without. Finally, through the application of multivariable logistic regression analysis, the incidence of depressive symptoms was found to have a significant association with social frailty (odds ratio 1.55; 95% confidence interval 1.10-2.20) but not with physical frailty or cognitive impairment. CONCLUSIONS: This study revealed that social frailty, in comparison with physical frailty and cognitive impairment, is more strongly associated with incidences of depressive symptoms among elderly.

    OBJECTIVE: Fear of falling (FOF) is a major health problem for older adults, present not just in fallers, but also nonfallers. This study examined the impact of FOF and fall history on disability incidence among community-dwelling older adults from a prospective cohort study. METHODS: A total of 5104 older adults living in community settings participated in baseline assessment and were followed up for about 4 years (median 52 mo, range 49-55 mo). At baseline, participants were assessed the presence of FOF and their fall history, and divided into 4 groups: Fall (-) FOF (-), Fall (+) FOF (-), Fall (-) FOF (+), and Fall (+) FOF (+). Disability incidence was defined as national long-term care insurance certification for personal support or care. RESULTS: During the follow-up period, 429 participants (9.9%) were newly certified as having a disability and needing personal support for long-term care insurance. Fall (-) FOF (+) group and Fall (+) FOF (+) group showed a significantly higher risk of disability incidence than Fall (-) FOF (-) group even after adjusting for covariates (Fall (-) FOF (+): hazard ratio 1.28, 95% confidence interval, 1.01-1.62, Fall (+) FOF (+): hazard ratio 1.44, 95% confidence interval, 1.05-1.98). CONCLUSIONS: Fear of falling could be a simple and useful predictor of disability incidence in community-dwelling older adults. Identifying and decreasing fall risk factors may prevent fall-related injuries, but excessive FOF may be associated with increased risk of disability incidence.

    Social frailty domains may play an important role in preventing physical decline and disability. The aim of this study is to examine the impact of social frailty as a risk factor for the future development of physical frailty among community-dwelling older adults who are not yet physically frail. A total of 1226 physically non-frail older adults were analyzed to provide a baseline. Participants completed a longitudinal assessment of their physical frailty 48 months later. Their baseline social frailty was determined based on their responses to five questions, which identified participants who went out less frequently, rarely visited friends, felt less like helping friends or family, lived alone and did not talk to another person every day. Participants with none of these characteristics were considered not to be socially frail; those with one characteristic were considered socially pre-frail; and those with two or more characteristics were considered socially frail. At the four-year follow-up assessment, 24 participants (2.0%) had developed physical frailty and 440 (35.9%) had developed physical pre-frailty. The rates of developing physical frailty and pre-frailty were 1.6% and 34.2%, respectively, in the socially non-frail group; 2.4% and 38.8%, respectively, in the socially pre-frail group; and 6.8% and 54.5%, respectively, in the socially frail group. Participants classified as socially frail at the baseline had an increased risk of developing physical frailty, compared with participants who were not socially frail (OR = 3.93, 95% CI = 1.02-15.15). Participants who were socially frail at the baseline also had an increased risk of developing physical pre-frailty (OR = 2.50, 95% CI = 1.30-4.80). Among independent community-dwelling older adults who are not physically frail, those who are socially frail may be at greater risk of developing physical frailty in the near future. Social frailty may precede (and lead to the development of) physical frailty.

    BACKGROUND: It remains unclear what kinds of behavior prevent the development of geriatric depression. This study aimed to elucidate behavioral predictors of increased depressive symptoms in older adults focusing on gender differences. METHODS: A total of 3106 community-dwelling older people aged older than or equal to 65 years without depressive symptoms at baseline participated. The 15-item Geriatric Depression Scale was used to assess depressive symptoms with a score of 6 or more at baseline and 15 month follow-up. Behavioral status was investigated by using dichotomous questions about the aspects of physical, cognitive, and social activities. Each category included 3 specific items. Demographic data and other potential confounding factors were also assessed. RESULTS: In the 15 month follow-up survey, 239 participants (7.7%) reported increased depressive symptoms. Multiple logistic regression analysis indicated that engagement in light physical exercise (odds ratio = 0.74, 95%, CI = 0.56-0.98), taking enrichment lessons (0.62, 0.46-0.85), using a personal computer (0.68, 0.48-0.97), participation in events at the community center (0.54, 0.40-0.72), and attending a community meeting (0.69, 0.52-0.92) were independently associated with lower risk of increased depressive symptoms. In a separate analysis for each gender, significant odds ratios of using a personal computer were observed in men, whereas significant odds ratios of light physical exercise, participation in events at the community center, and attending a community meeting were observed in women. CONCLUSIONS: Light physical exercise, taking lessons, usage of a computer, and participation in community events showed protective effects against depressive symptoms. However, the significance of each behavioral factor may vary according to gender.

    AIM: To evaluate the relationship between kidney function without diabetes and components of the frailty phenotype in community-dwelling Japanese older adults. METHODS: Participants were 8343 residents who completed baseline assessments, classified into four categories according to eGFR. Frailty status was defined using five criteria: (i) slow gait speed; (ii) muscle weakness; (iii) low physical activity; (iv) exhaustion; and (v) unintentional weight loss. RESULTS: After multivariate adjustment, participants with the lowest kidney function were at higher risk of frailty (OR 1.57, 95% CI 1.02-3.50) than those with normal kidney function. In addition, after adjustment for multiple confounders, estimated glomerular filtration rate <30 was associated with a greater risk of the individual frailty components of weight loss (OR 2.14, 95% CI 1.11-4.12), low physical activity (OR 1.35, 95% CI, 1.01-2.54) and slowness (OR 1.82, 95% CI 1.36-3.77) compared with estimated glomerular filtration rate ≥60. CONCLUSIONS: Lower kidney function was associated with a higher risk of weight loss, low physical activity and slowness among community-dwelling Japanese older adults.

    OBJECTIVE: This study examined the association between excessive daytime sleepiness (EDS) and gait characteristics (e.g., speed, variability) in community-dwelling older adults. METHOD: This cross-sectional study included 3,901 individuals aged ≥65 years. Participants answered questions about EDS, sleep duration, and other sleep-related symptoms. Gait speed, stride length, and the variability in stride length were assessed by using a stopwatch and a WalkWay device. RESULTS: EDS was significantly associated with slower gait speed among younger subjects (<75 years, p = .021) and with both slower gait speed ( p = .045) and greater variability in stride length among older subjects (≥75 years, p = .048) in a multivariate analysis adjusted for age, sex, body mass index, medication, number of comorbidities, and education. DISCUSSION: EDS associates with gait ability, particularly in older old adults. Further prospective studies are needed to determine the causal association between gait ability and sleep disturbances, including EDS.

    Objectives: Frailty is a course experienced in advanced aging. Identification of a biological factor associated with frailty is required. Although serum insulin-like growth factor-1 (IGF-1) is a potential factor related with frailty, consensus has not been reached regarding this relationship. This study aimed to investigate the association between IGF-1 and frailty in older adults. Design: Cross-sectional study. Setting: Cohort study that was part of the “National Center for Geriatrics and Gerontology–Study of Geriatric Syndromes.” Participants: The study participants were 4133 older adults (mean age, 71.8 ± 5.4 years). Measurements: We assessed serum IGF-1 levels and frailty status and collected demographic variables, including cognitive function, as covariates. Results: Frailty and pre-frailty were present in 274 subjects (7%) and 1930 subjects (47%), respectively. Subjects were divided into four groups based on quartiles of IGF-1 levels. Multinomial logistic analysis showed that the lowest group had significant odds of pre-frailty (crude model: odds ratio [OR] 1.58, 95% confidence interval [CI] 1.30–1.90, p OpenSPiltSPi.001
    adjusted model: OR 1.38, 95% CI 1.13–1.68, p =.002) and frailty (crude model: OR 3.42, 95% CI 2.38-4.92, p OpenSPiltSPi.001
    adjusted model: OR 1.54, 95% CI 1.02–2.32, p =.039), compared with the highest group. Conclusion: Lower serum IGF-1 levels were independently related with frailty in older adults.

    OBJECTIVES: In this paper and prospective study, we examine the number of healthy behaviors and the incidence of disability in community-dwelling older adults aged 65 years and older. METHODS: Participants (N = 4483) were residents of Obu, Japan who were asked about regular exercise, smoking status, and sleep duration. Demographic variables, history of disease, physi- cal function, and cognitive function were measured as confounders. Information about disabil- ity was obtained from the Obu City Office. RESULTS: At 24 months after baseline assessment, 165 participants (3.7%) were certified as having disability. Participants with 2 healthy behaviors had a 1.61-fold increased risk of disability (95% CI: 1.08 -2.42) compared with those with 3 healthy behaviors; those with one or no healthy behaviors had a 2.01-fold risk (95% CI: 1.26-3.19) even though adjusting for confounders. CONCLUSIONS: The number of healthy behaviors was associated with the incidence of disability, with the hazard ratios increasing progressively as the number of healthy behaviors decreased.

    [Purpose] This study developed a chart for predicting stroke patients' independence of gait during the convalescent period. [Subjects and Methods] Two hundred fifty-one first-time stroke patients were enrolled in this study. Physical and cognitive functions, basic movement ability, balance ability and activities of daily living were evaluated on admission to a rehabilitation ward for the convalescent stage. Based on this information, a decision tree for predicting independence of gait three months later was developed using signal detection analysis. [Results] Independence in rising motion, balance ability, and cognitive function were extracted as significant predictors. A valid and reliable decision tree was developed. [Conclusion] A chart for predicting independence of gait was developed. This chart is appropriate for the convalescent period after stroke.

    AIM: The present prospective study was carried out to determine whether participation in community-based intervention studies exerted a positive impact on disability prevention in older adults with physical frailty. METHODS: A total of 514 community-dwelling older adults (aged ≥65 years) with physical frailty who had undergone baseline assessment and participated in community-based intervention studies (participants) or did not (non-participants) were included in the present study. Non-participants were selected through propensity score matching, to balance potential covariates at baseline. Disability incidence was followed up at 48 months as a main outcome. Demographic data (age, sex and medical history), global cognitive function, grip strength, walking speed, and blood test results including serum albumin and brain-derived neurotrophic factor at baseline were included as covariates. RESULTS: Disability incidence rates differed significantly between participants (11.3%) and non-participants (19.8%) of community-based intervention studies during the 48-month follow-up period (P = 0.007). Participation in community-based intervention studies (hazard ratio 0.55, 95% confidence interval 0.35-0.88) was significantly associated with the incidence of disability in older adults with physical frailty. CONCLUSIONS: Participation in community-based intervention studies could reduce the incidence of disability in older adults with physical frailty. Thus, strategies designed to increase the number of participants in community-based intervention programs should be considered in community-based approaches for the prevention of disability in older adults with physical frailty.

    AIM: Numerous neuropsychological tests are implemented in the clinical setting. However, a readily available cognitive test is required to detect the risk of dementia in the community setting. METHODS: A total of 4151 persons aged ≥65 years participated in the present prospective cohort study. We assessed cognitive performance using the Mini-Mental State Examination and the National Center for Geriatrics and Gerontology-Functional Assessment Tool. The National Center for Geriatrics and Gerontology-Functional Assessment Tool includes tests of story and word list memory, attention and executive function, processing speed, and visuospatial skill to screen for cognitive impairment. All measurements were transformed to Z-scores to compare among the cognitive tests. The incidence of dementia was determined using data collected by the Japanese Health Insurance System over 36 months. RESULTS: After an average of 43 months, 180 (4.3%) participants were diagnosed with dementia. Survival analyses showed that the probability of dementia was significantly associated with all cognitive tests, except for visuospatial skill. The processing speed test showed the highest hazard ratios for the incidence of dementia (Z-score: hazard ratio 0.61, 95% confidence interval 0.50-0.75, P < 0.01). In subgroup analysis, there were no significant relationships between cognitive tests and the incidence of dementia in participants without global cognitive impairment. CONCLUSIONS: We conclude that the National Center for Geriatrics and Gerontology-Functional Assessment Tool, as well as the Mini-Mental State Examination, play an important role in detecting the risk of dementia in the community setting. Further analysis is required to identify the risk of dementia in older people without global cognitive impairment. Geriatr Gerontol Int 2017; 17: 2383-2388.

    AIM: Fear of falling (FOF) is associated with spatial and temporal gait parameters in older adults. FOF is prevalent among older adults, both those with and without fall history. It is still unclear whether the relationships between FOF and gait parameters are affected by fall history. The aim of the present study was to compare gait parameters by the presence of FOF and fall history. METHODS: A total of 3575 older adults (mean age 71.7 years, 49.7% female) met the inclusion criteria for the present study. We assessed the presence of fall history and FOF by face-to-face interview, and gait parameters (gait speed, stride length, step rate, double support time and variation of stride length) at a comfortable speed using a computerized electronic walkway. RESULTS: Prevalences of fall history and FOF were as follows: non-fallers without FOF 52.6% (n = 1881); fallers without FOF 6.3% (n = 227); non-fallers with FOF 34.4% (n = 1229); and fallers with FOF 6.7% (n = 238). Analysis of covariance showed significant differences among the four groups in all gait variables even after adjusting for age, sex and number of medications used. It should be noted that non-fallers with FOF showed significantly slower gait speed, shorter stride length and longer double support time than did non-fallers without FOF (P < 0.001). CONCLUSIONS: The present results suggest that spatial and temporal gait parameters are influenced by FOF, even in the absence of fall history. The assessment of FOF might be helpful for better understanding of age-related changes in gait control. Geriatr Gerontol Int 2017; 17: 2455-2459.

    AIM: The aim of the present study was to investigate the association between various body composition parameters and the risk of mild cognitive impairment (MCI) in older Japanese adults, as well as potential sex-related differences in the risk of MCI. METHODS: Participants underwent cognitive tests, and were divided into 840 participants with MCI (mean age 71.9 ± 5.5 years) and 1740 without MCI (mean age 71.3 ± 5.2 years). Body composition parameters were measured using a bioelectrical impedance analyzer. Multiple logistic regression analysis was then carried out to examine the associations between body composition parameters and risk of MCI. RESULTS: After adjusting for confounding factors, those in the lowest quartile for fat-free mass had a higher risk of MCI than those in the highest quartile (men: odds ratio [OR] 1.96, 95% confidence interval CI 1.24-3.10; women: OR 1.49, 95% CI 1.01-2.19). Loss of muscle mass in the upper (OR 2.17, 95% CI 1.40-3.37) and lower (OR 1.99, 95% CI 1.25-3.15) limbs was associated with a higher MCI risk in men. However, only loss of muscle mass in the lower limbs was associated with a higher MCI risk (OR 1.61, 95% CI 1.06-2.44) in women. No associations were found between obesity measures and MCI. CONCLUSIONS: We found that loss of fat-free mass was associated with MCI in older adults, regardless of sex. We also found that appendicular muscle mass was more closely associated with MCI in men than in women. These results suggest that the association between appendicular muscle mass and MCI might have different underlying mechanisms based on sex. Geriatr Gerontol Int 2017; 17: 2053-2059.

    OBJECTIVES: Approximately 25% of individuals who are diagnosed with amnestic mild cognitive impairment (aMCI) revert to normal cognition (NC) rather than progressing to Alzheimer disease (AD). However, the prevalence of progression and reversion among older people in Asia remains unclear. DESIGN: A prospective cohort study. SETTING: A community in Japan. PARTICIPANTS: A total of 4153 individuals without dementia aged ≥65 years were classified as having NC, aMCI single domain (aMCIs), non-aMCI single domain (naMCIs), aMCI multiple domain (aMCIm), non-aMCI multiple domain (naMCIm), or global cognitive impairment (GCI). MEASUREMENTS: The National Center for Geriatrics and Gerontology-Functional Assessment Tool and the Mini-Mental State Examination were used to conduct cognitive screening. The participants completed baseline (August 2011 to June 2012) and follow-up (August 2015 to June 2016) assessments. We followed up monthly for newly incident AD, as recorded by the Japanese National Health Insurance and Later-Stage Medical Care systems. Multiple imputation was used to adjust for selection bias and loss of information. RESULTS: At 4-year follow-up, the reversion rates to NC in aMCIs, naMCIs, aMCIm, naMCIm, and GCI were 38.7%, 57.0%, 25.7%, 20.9%, and 43.7%, respectively. Of the participants with NC, aMCIs, naMCIs, aMCIm, naMCIm, and GCI at baseline, 4.7%, 4.5%, 13.1%, 20.6%, 21.6%, and 14.3%, respectively, were subsequently diagnosed with AD. We found significant associations between incident AD and naMCIs [hazard ratio (HR) compared to NC: 2.18, 95% confidence interval (CI): 1.45-3.26], and between AD and aMCIm (HR: 4.39, 95% CI: 2.06-9.39) and between AD and naMCIm (HR: 3.60, 95% CI: 2.13-6.08). However, the association between incident AD and aMCIs and between AD and GCI did not reach significance. CONCLUSION: Reversion to NC from MCI and GCI was frequent, and individuals with aMCIs and GCI did not show higher risk of incident AD than those with NC. Older adults with multiple cognitive impairments may be potential targets for preventing dementia.

    BACKGROUND: The aim of this study was to describe the age-dependent changes in the parameters of physical performance and body composition in Japanese older adults who are independently dwelling in the community. We also examined whether the age-dependent changes differ among physical performance and body composition parameters. METHODS: Cross-sectional data from 10 092 community-dwelling older adults (mean age 73.6 years; 5296 women) were analyzed. The measures of physical performance included hand-grip strength, the five-times-sit-to-stand test, and walking speed. Body composition parameters (body weight, fat mass, and appendicular skeletal muscle mass) were measured with a bioelectrical impedance analyser. Correlations between age and the physical performance and body composition parameters were tested. The T-scores of physical performance and body composition measurements were calculated and presented according to 5-year age groups to examine the differences in age-dependent changes in physical performance and body composition parameters. RESULTS: All physical performance measures significantly decreased with aging. The cumulative mean T-scores according to age group showed different age-dependent changes between body mass index (BMI) and appendicular skeletal muscle mass index (ASMI) (cumulative mean T-score change of BMI and ASMI of -5.7 to -2.9 and -12.7 to -12.1, respectively). The slope declines in age-associated changes were greater in grip strength (β = -0.77, 95% confidence interval = -0.82 to -0.76) for men and in walking speed (β = -0.95, 95% confidence interval = -0.99 to -0.90) for women. CONCLUSIONS: The patterns of age-dependent decreases in physical performance measures differed among parameters and between sexes. There is a possibility of a difference in the age-related slope patterns among parameters; decreases in grip strength in men and walking speed in women may be more prominent with advancing age. Furthermore, the decrease in ASMI with age is more striking than that of BMI.

    OBJECTIVES: Our objective was to investigate the association between social frailty and cognitive and physical function among older adults. DESIGN: This was a cross-sectional study. SETTING: We examined community-dwelling adults in Japan. PARTICIPANTS: Participants comprised 4425 older Japanese people from the National Center for Geriatrics and Gerontology-Study of Geriatric Syndromes. MEASUREMENTS: Social frailty was defined by using responses to 5 questions (going out less frequently, rarely visiting friends, feeling unhelpful to friends or family, living alone, and not talking with someone every day). Participants showing none of these components were considered nonfrail; those showing 1 component were considered prefrail; and those showing 2 or more components were considered frail. To screen for cognitive deficits, we assessed memory, attention, executive function, and processing speed. Having 2 or more tests with age-adjusted scores of at least 1.5 standard deviations below the reference threshold was sufficient to be characterized as cognitively deficient. To screen for physical function deficits, we assessed walking speed (<1.0 m/s cut-off) and grip strength (<26 kg for men; <18 kg for women cut-off). Scoring below the cut-off point on 1 or more tests was sufficient to be characterized as physically deficient. RESULTS: The prevalence of social frailty was the following: nonfrailty, 64.1% (N = 2835); social prefrailty, 24.8% (N = 1097); social frailty, 11.1% (N = 493; P for trend < .001). All cognitive function tests (word list memory, Trail Making Test parts A and B, and the symbol digit-substitution task) significantly varied between social frailty groups; physical function (gait speed and grip strength) also varied between social frailty groups (all Ps for trend <.001). Referred to social nonfrailty, social frailty was independently associated with each cognitive deficit (odds ratio = 1.61, 95% confidence interval 1.13-2.30) and deficits in physical function (odds ratio = 1.99, 95% confidence interval 1.57-2.52) after adjusting for covariates. CONCLUSIONS: This study revealed that social frailty is associated with both cognitive and physical function among Japanese older adults. And social frailty status was also negatively associated with physical function. Further studies are needed to elucidate if a casual association exists between social frailty and cognitive and physical function.

    Background: Physical activity may preserve neuronal plasticity, increase synapse formation, and cause the release of hormonal factors that promote neurogenesis and neuronal function. Previous studies have reported enhanced neurocognitive function following exercise training. However, the specific cortical regions activated during exercise training remain largely undefined. In this study, we quantitatively and objectively evaluated the effects of exercise on brain activity during walking in healthy older adults.
    Methods: A total of 24 elderly women (75-83 years old) were randomly allocated to either an intervention group or a control group. Those in the intervention group attended 3 months of biweekly 90-min sessions focused on aerobic exercise, strength training, and physical therapy. We monitored changes in regional cerebral glucose metabolism during walking in both groups using positron emission tomography (PET) and [F-18] fluorodeoxyglucose (FDG).
    Results: All subjects completed the 3-month experiment and the adherence to the exercise program was 100%. Compared with the control group, the intervention group showed a significantly greater step length in the right foot after 3 months of physical activity. The FDG-PET assessment revealed a significant post-intervention increase in regional glucose metabolism in the left posterior entorhinal cortex, left superior temporal gyrus, and right superior temporopolar area in the intervention group. Interestingly, the control group showed a relative increase in regional glucose metabolism in the left premotor and supplemental motor areas, left and right somatosensory association cortex, and right primary visual cortex after the 3-month period. We found no significant differences in FDG uptake between the intervention and control groups before vs. after the intervention.
    Conclusion: Exercise training increased activity in specific brain regions, such as the precuneus and entorhinal cortices, which play an important role in episodic and spatial memory. Further investigation is required to confirm whether alterations in glucose metabolism within these regions during walking directly promote physical and cognitive performance.

    OBJECTIVE: To test the hypothesis that a long-term, structured cognitive leisure activity program is more effective than a health education program at reducing the risk of further cognitive decline in older adults with mild cognitive impairment syndrome (MCI), a high risk for dementia. DESIGN: A 3-arm, single-blind randomized controlled trial. SETTING: Community. PARTICIPANTS: A total of 201 Japanese adults with MCI (mean age: 76.0 years, 52% women). INTERVENTIONS: Participants were randomized into 1 of 2 cognitive leisure activity programs (60 minutes weekly for 40 weeks): dance (n = 67) and playing musical instruments (n = 67), or a health education control group (n = 67). MEASUREMENTS: Primary outcomes were memory function changes at 40 weeks. Secondary outcomes included changes in Mini-Mental State Examination and nonmemory domain (Trail Making Tests A and B) scores. RESULTS: At 40 weeks, the dance group showed improved memory recall scores compared with controls [mean change (SD): dance group 0.73 (1.9) vs controls 0.01 (1.9); P = .011], whereas the music group did not show an improvement compared with controls (P = .123). Both dance [mean change (SD): 0.29 (2.6); P = .026] and music groups [mean change (SD): 0.46 (2.1); P = .008] showed improved Mini-Mental State Examination scores compared with controls [mean change (SD): -0.36 (2.3)]. No difference in the nonmemory cognitive tests was observed. CONCLUSIONS: Long-term cognitive leisure activity programs involving dance or playing musical instruments resulted in improvements in memory and general cognitive function compared with a health education program in older adults with MCI. TRIAL REGISTRATION: UMIN-CTR UMIN000014261.

    Background. Lower extremity functioning is important for maintaining activity in elderly people. Optimal cutoff points for standard measurements of lower extremity functioning would help identify elderly people who are not disabled but have a high risk of developing disability.
    Objective. The purposes of this study were: (1) to determine the optimal cutoff points of the Five-Times Sit-to-Stand Test and the Timed "Up & Go" Test for predicting the development of disability and (2) to examine the impact of poor performance on both tests on the prediction of the risk of disability in elderly people dwelling in the community.
    Design. This was a prospective cohort study.
    Methods. A population of 4,335 elderly people dwelling in the community (mean age=71.7 years; 51.6% women) participated in baseline assessments. Participants were monitored for 2 years for the development of disability.
    Results. During the 2-year follow-up period, 161 participants (3.7%) developed disability. The optimal cutoff points of the Five-Times Sit-to-Stand Test and the Timed "Up & Go" Test for predicting the development of disability were greater than or equal to 10 seconds and greater than or equal to 9 seconds, respectively. Participants with poor performance on the Five-Times Sit-to-Stand Test (hazard ratio= 1.88; 95% CI= 1.11-3.20), the Timed " Up & Go" Test (hazard ratio= 2.24; 95% CI= 1.42-3.53), or both tests (hazard ratio= 2.78; 95% CI= 1.78-4.33) at the baseline assessment had a significantly higher risk of developing disability than participants who had better lower extremity functioning.
    Limitations. All participants had good initial functioning and participated in assessments on their own. Causes of disability were not assessed.
    Conclusions. Assessments of lower extremity functioning with the Five-Times Sit-toStand Test and the Timed "Up & Go" Test, especially poor performance on both tests, were good predictors of future disability in elderly people dwelling in the community.

    OBJECTIVES: The present study examined the association between anorexia of aging and physical frailty among older people. STUDY DESIGN: An observational, cross-sectional cohort design was used with a sample of 4417 elderly Japanese citizens living in a community setting. MAIN OUTCOME MEASURES: Frailty was operationalized as the following frailty components: slowness, weakness, exhaustion, low level of physical activity, and weight loss. Participants were grouped as non-frail, pre-frail, and frail, and categorized as anorexic or not using questionnaire cutoff scores. Measured covariates were as follows: sociodemographic variables, medical history, life style, body mass index, blood nutrition data, self-rated health, depressive symptoms, and cognitive function. RESULTS: The prevalence of anorexia of aging in each group was as follows: non-frail, 7.9%; pre-frail, 14.8%; frail, 21.2% (P for trend<0.001). After adjusting for all covariates, independent associations were identified between anorexia of aging and slowness (OR 1.42, 95% CI: 1.14-1.75, P=0.002), exhaustion (OR 1.39, 95% CI: 1.11-1.74, P=0.004) and weight loss (OR 1.37, 95% CI: 1.05-1.79, P=0.019), but not weakness or low level of physical activity. CONCLUSIONS: Anorexia of aging is importantly associated with frailty and the following frailty components: slowness, exhaustion, and weight loss. Future research should prospectively examine frailty's causal connection with anorexia of aging.

    AIM: The purpose of the present study was to examine whether the combination of subjective sleep quality and physical activity is associated with cognitive performance among community-dwelling older adults. METHODS: Cross-sectional data on 5381 older adults who participated in part of the National Center for Geriatrics and Gerontology - Study of Geriatric Syndromes were analyzed. We assessed general cognitive impairment using the Mini-Mental State Examination, and also assessed story memory, attention, executive function and processing speed using the National Center for Geriatrics and Gerontology Functional Assessment Tool. Physical activity was assessed using two questionnaires, and participants were categorized as active or inactive. Sleep quality was assessed using the Pittsburgh Sleep Quality Index, and participants were categorized as having poor (PS) or good sleep quality (GS). RESULTS: Participants in the inactive + PS group had worse performances than those in the active + GS group in all cognitive measures (Mini-Mental State Examination: P = 0.008, story memory: P = 0.007, other cognitive measures: P < 0.001), and also had worse performances than those in the inactive + GS and active + PS groups in the trail-making test, part B, and the symbol digit substitution test (P < 0.001, respectively). Additionally, participants in the inactive + GS group had worse performances than in the active + GS in the trail-making test, part B, and the symbol digit substitution test (P = 0.002 and P = 0.001, respectively). CONCLUSIONS: Inactivity and poor sleep quality were associated with poor cognitive performance among community-dwelling older adults. The combination of poor sleep quality and physical inactivity also worsened cognitive performance. Geriatr Gerontol Int 2017; 17: 1823-1828.

    OBJECTIVE: This study aimed to investigate whether sitting time, as a form of sedentary behaviour, is related to incident depressive symptoms in older people. METHODS: This study included 3503 participants (mean age 71.7 years, 50.1% female) from the 'Obu Study of Health Promotion for the Elderly' cohort study. At baseline and then 15 months later, the participants reported their status of depressive symptoms using the 15-item Geriatric Depression Scale. During the baseline assessment, the participants were also asked about their sedentary behaviour on weekdays over the past 7 days and, from there, categorized into three groups (<240, 240-480, ≥480 min/day). Demographic data and the other health behaviours were also assessed at the baseline. RESULTS: Cross-sectional analysis revealed that 437 participants (12.0%) had depressive symptoms. In a prospective analysis, the logistic regression model revealed that the odds ratio for depressive symptom incidence was higher in participants who, at baseline, spent 480 min or more per day sitting (1.636; 95% confidence interval [CI] 1.015 to 2.636, p = 0.043), and in those who spent 240-480 min (1.605; 95% CI 1.085 to 2.375, p = 0.018) in comparison with those who spent less than 240 min. CONCLUSIONS: Sedentary behaviour significantly affects the risk of incident depressive symptoms. Further research is needed to develop an intervention strategy to manage depressive symptoms, as the second most common cause of burden of disease among older adults.

    Objective: Although subjective memory complaints (SMCs) are considered a risk factor for incident dementia in older people, the effect might differ based on cognitive function. The aim of the present study was to investigate whether the effect of SMCs on the incidence of dementia in older people differed based on cognitive function. Design: A 24-month follow-up cohort study. Setting: Japanese community. Participants: Prospective, longitudinal data for incident dementia were collected for 3,672 participants (mean age: 71.7 years; 46.5% men) for up to 24 months. Measurements: Baseline measurements included covariates for incident dementia, SMCs, and cognitive function. Associations between SMCs, cognitive impairment, and incident dementia were examined using Cox proportional hazards models. Results: Incidences of dementia in the cognitively intact without SMC, cognitively intact with SMC, cognitive impairment without SMC, and cognitive impairment with SMC groups were 0.3%, 1.8%, 3.4%, and 4.8%, respectively. In the cognitively intact participants, SMCs were associated with a significantly higher risk of dementia (hazard ratio [HR]: 4.95, 95% confidence interval [CI]: 1.52-16.11, p = 0.008). Incident dementia with cognitive impairment was not significantly different based on SMC presence (p = 0.527). Participants with cognitive impairment in multiple domains had a significantly higher risk of incident dementia (HR: 2.07, 95% CI: 1.01-4.24, p = 0.046) Conclusion: SMCs were related with dementia in cognitively intact older people, but not in those with cognitive impairment. Multiple domains of cognitive impairment were associated with a higher risk of incident dementia.

    <p>【はじめに,目的】身体的フレイルとは包括的に機能が低下した脆弱化した状態を指し,健常高齢者と要介護高齢者の中間的存在とされている。要介護の主要因の一つである転倒は,要介護リスクが高いフレイル高齢者において,特に予防すべき事象である。近年,認知機能の低下が,転倒リスクを高めることが明らかとなってきている。フレイル高齢者の転倒予防を考えていく上で,認知機能低下が転倒とどのように関連しているのか検討することが必要だが,十分に明らかにされていない。そこで,本研究の目的は身体的フレイル高齢者における認知機能低下と転倒との関連性を検討することとする。</p><p></p><p></p><p>【方法】地域高齢者10885名のうち,パーキンソン病・認知症既往者,MMSEが21点未満の者,基本的ADLに障害のある者を除く9990名(平均73.5歳)を対象とした。歩行速度低下,筋力低下,体重減少,易疲労感,身体活動量低下の5項目の内,3項目以上が該当したものを身体的フレイルと判定した。認知機能に関しては,記憶・注意機能・遂行機能・処理速度の評価を行い,年齢・教育歴で標準化したデータにもとづき1.5SD以上の機能低下を1領域でも認めた者は認知機能低下ありと定義した。その上で,健常群,認知機能低下群,フレイル群,フレイル+認知機能低下群の4群に分けた。転倒については,過去1年間の転倒経験の有無を聴取し,転倒に伴う骨折の有無も合わせて聴取した。統計解析は,従属変数に転倒経験の有無,独立変数に群要因(健常群を参照値)と共変量を投入した多変量ロジスティック回帰分析を実施した。</p><p></p><p></p><p>【結果】転倒経験のある者は,健常群15.7%,認定機能低下群18.6%,フレイル群28.4%,フレイル+認知機能低下群31.6%であった。転倒経験の有無を従属変数としたロジスティック回帰分析において,健常群を参照としたオッズ比は,認知機能低下群で1.17(95%CI 1.03-1.34),フレイル群で1.48(95%CI 1.19-1.83),フレイル+認知機能低下群で1.77(95%CI 1.39-2.27)であった。転倒経験を有する者を抽出し,転倒後の骨折経験の有無を従属変数としたロジスティック回帰分析において,健常群を参照値としたオッズ比は,フレイル+認知機能群にのみ有意な関連が認められた(2.56(95%CI 1.36-4.85))。</p><p></p><p></p><p>【結論】転倒に伴う骨折については,身体的フレイルと認定機能低下を併せ持つ高齢者のみ関連性みられた。横断研究のため,因果関係は言及できないが身体的フレイルに認知機能低下が合わさることにより,転倒回避行動の遅延などが生じ,転倒後に生じる骨折との関連が強くなるのではないかと考えられる。一方で,転倒後に骨折した身体的フレイル高齢者の認知機能が低下しているということも考えられるため,今後は前方視的な研究の中で関係性を検討する必要がある。</p>

    BACKGROUND: It is important to examine the etiology of motoric cognitive risk syndrome (MCR) and its association with dementia and disability to obtain biological insights and to develop preventive strategies. OBJECTIVE: This study aimed to examine the association of MCR with incidence of dementia and disability in a Japanese community-dwelling sample of older adults. METHODS: Participants were 4,235 older adults (50% women, mean age: 72.0 years). MCR was diagnosed at baseline using established criteria in non-demented seniors with self-reported cognitive complaints and slow gait. Incident cases of dementia were identified from insurance data monthly. Disability was regarded as certification by long-term care insurance. RESULTS: At baseline, 265 participants (6.3%) met criteria for MCR. During follow-up (mean duration: 29 months), there were 138 incident cases of dementia (3.3%) and 207 incident cases of disability (4.9%). Cox-proportional hazards models, adjusted for demographical data, lifestyle, and medical conditions, showed that presence of MCR at baseline was a major risk factor for developing dementia (HR 2.49, 95% CI 1.52-4.10, p < 0.001). MCR also predicted risk for disability (HR 1.69, 95% CI 1.08-2.02, p < 0.001). CONCLUSIONS: MCR is helpful in the short-term prediction of risk for dementia and disability in the elderly Japanese population. Identification of seniors with MCR is recommended for early detection and instituting preventive measures for reducing the risk of dementia and disability.

    BACKGROUND: The associations between components of metabolic syndrome (MetS) and mild cognitive impairment (MCI) subtypes remain unclear. OBJECTIVE: The study aim was to identify the prevalence of MetS for MCI subtypes and to investigate sex differences in the association between MetS and MCI subtypes in older Japanese adults. METHODS: The study analyzed data from 3,312 men and women aged 70 years or more. MetS was diagnosed according to International Diabetes Federation criteria. Participants completed cognitive tests and were categorized into normal cognition, amnestic MCI (aMCI), and non-amnestic MCI (naMCI). The associations between MetS and its components and MCI subtypes were analyzed using multiple logistic regression. RESULTS: MetS prevalence was greater in participants with naMCI (men: p = 0.030; women: p = 0.040). Participants with naMCI showed higher odds ratios (OR) of MetS (men: 2.45, 95% confidence intervals (CI): 1.13-5.32; women: OR: 1.94, 95% CI: 1.12-3.39) compared with participants with normal cognition. MetS was not associated with aMCI. Analysis of MetS components showed that raised glucose (OR: 1.62, 95% CI: 1.19-2.22) and reduced high-density lipoprotein cholesterol (OR: 1.97, 95% CI: 1.25-3.12) were associated with naMCI in men. In women, raised blood pressure (OR: 1.42, 95% CI: 1.03-1.94) and raised glucose (OR: 1.32, 95% CI: 1.02-1.71) were associated with naMCI. CONCLUSION: MetS was associated only with naMCI regardless of sex, which suggests etiologic differences in MCI subtypes. We also found sex differences in the relationship between naMCI risk and MetS and its components.

    AIM: Memory dysfunction is a major component of age-related cognitive decline, and is a marker of cognitive impairment. Emerging evidence suggests that the prefrontal cortex is required for maintenance of memory functions. The purpose of the present study was to elucidate age-related changes in prefrontal oxygenation during memory encoding and retrieval using near-infrared spectroscopy. METHODS: We examined 21 young (mean age 24.3 years), 52 young-old (mean age 69.7 years) and 50 old-old (mean age 79.5 years) participants. The concentration of oxyhemoglobin, which is a reliable biomarker of changes in regional cerebral blood flow, in the right and left prefrontal cortex was measured during encoding and delayed retrieval of a list of 10 target words. The average number of correct answers in the retrieval task was used as a measure of task performance. RESULTS: During encoding, oxyhemoglobin was significantly and bilaterally lower in young-old and old-old participants compared with young participants. Meanwhile, during retrieval, only old-old participants showed significantly decreased oxyhemoglobin compared with young and young-old participants. The old-old participants showed fewer correct answers in the retrieval period than the young and young-old participants. CONCLUSIONS: Old-old participants showed reduced prefrontal oxygenation during both encoding and retrieval, and decreased memory performance compared with younger participants. It is necessary for the clinical application of near-infrared spectroscopy to consider the effects of demographic variables on cerebral oxygenation. Geriatr Gerontol Int 2016; 16: 1296-1304.

    BACKGROUND: Older adults with mild cognitive impairment (MCI) are non-demented, but demonstrate cognitive dysfunction, and have significantly higher risk of progressing to dementia. A better understanding of more sensitive risk factors, such as combination of cognitive and psychological status, for progression of MCI to dementia may be crucial for prevention of development of dementia. OBJECTIVE: To examine MCI, depressive symptoms, and comorbid MCI and depressive symptoms as risk factors for development of dementia. METHODS: A total of 3,663 community-dwelling older people were included in this prospective longitudinal study. MCI was determined by age- and education-adjusted objective cognitive impairment using computerized comprehensive cognitive measures including memory, attention/executive function, and processing speed. Depressive symptoms were measured using the 15-item Geriatric Depression Scale (GDS) and defined by a GDS score of 6 or more. RESULTS: During the 24-month follow-up period, 72 participants (2.0%) developed dementia. Baseline MCI was significantly associated with an increased risk of incident dementia (hazard ratio [HR], 3.2; 95% confidence interval [CI], 1.8-5.5) but depressive symptoms were not (2.0; 1.0-4.2) after adjusting for age, sex, education, prescribed medications, and walking speed. Participants with comorbid MCI and depressive symptoms at baseline had a higher risk of developing dementia (HR, 4.8; 2.3-10.5). CONCLUSION: Although MCI and depressive symptoms may be associated with increased risk for incident dementia independently, comorbid MCI and depressive symptoms have a significantly greater impact on dementia development among community-dwelling older adults.

    BACKGROUND AND PURPOSE: In dual-task situations, postural control is closely associated with attentional cost. Previous studies have reported age-related differences between attentional cost and postural control, but little is known about the association in conditions with a one-legged standing posture. The purpose of this study was to determine age-related differences in postural control and attentional cost while performing tasks at various difficulty levels in a one-legged standing posture. METHODS: In total, 29 healthy older adults aged 64 to 78 years [15 males, 14 females, mean (SD) = 71.0 (3.8) years] and 29 healthy young adults aged 20 to 26 years [14 males, 15 females, mean (SD) = 22.5 (1.5) years] participated in this study. We measured the reaction time, trunk accelerations, and lower limb muscle activity under 3 different one-legged standing conditions-on a firm surface, on a soft surface with a urethane mat, and on a softer more unstable surface with 2 piled urethane mats. Reaction time as an indication of attentional cost was measured by pressing a handheld button as quickly as possible in response to an auditory stimulus. A 2-way repeated-measures analysis of variance was performed to examine the differences between the 3 task conditions and the 2 age groups for each outcome. RESULTS AND DISCUSSION: Trunk accelerations showed a statistically significant group-by-condition interaction in the anteroposterior (F = 9.1, P < .05), mediolateral (F = 9.9, P < .05), and vertical (F = 9.3, P < .05) directions. Muscle activity did not show a statistically significant group-by-condition interaction, but there was a significant main effect of condition in the tibialis anterior muscle (F = 33.1, P < .01) and medial gastrocnemius muscle (F = 14.7, P < .01) in young adults and the tibialis anterior muscle (F = 24.8, P < .01) and medial gastrocnemius muscle (F = 10.8, P < .01) in older adults. In addition, there was a statistically significant interaction in reaction time (F = 8.2, P < .05) for group-by-condition. CONCLUSIONS: The study results confirmed that reaction times in older adults are more prolonged than young adults in the same challenging postural control condition.

    AIM: The aim of the present study was to evaluate the relationship between kidney function with concomitant diabetes or hypertension and frailty in community-dwelling Japanese older adults. METHODS: The participants were 9606 residents (community-dwelling Japanese older adults) who completed baseline assessments. The estimated glomerular filtration rate (mL/min/1.73 m2 ) was determined according to the serum creatinine level, and participants were classified into four mutually exclusive categories: ≥60.0 (normal range), 45.0-59.9, 30.0-44.9 and <30.0 mL/min/1.73 m2 . Frailty status was defined using five criteria as described by Fried: slow gait speed, muscle weakness, low physical activity, exhaustion and unintentional weight loss. Participants who met three, four or five criteria satisfied the definition of having frailty. Multivariate logistic regression was used to examine the relationships between estimated glomerular filtration rate and frailty. RESULTS: After multivariate adjustment, participants with lower kidney function (estimated glomerular filtration rate <30.0 mL/min/1.73 m2 ) were more frail (odds ratio [OR] 1.90, 95% confidence interval [CI] 1.01-3.59). In addition, individuals with a history of diabetes (OR 2.76, 95% CI 1.21-8.24) or hypertension (OR 2.53, 95% CI 1.45-5.12) showed a significantly increased risk of frailty in the lower kidney function group, regardless of multivariate controls. Furthermore, the analyses showed an even greater increase in the risk of frailty in patients with a history of both diabetes and hypertension (OR 3.67, 95% CI 1.13-14.1) CONCLUSIONS: A lower level of kidney function was associated with a higher risk of frailty in community-dwelling Japanese older adults.

    OBJECTIVE: Although sleep disturbances are associated with disability among older adults, no longitudinal study has examined the impact of sleep assessed based on both sleep quality and quantity on incident disability. This study examined whether sleep duration and excessive daytime sleepiness were associated with incidence of disability in community-dwelling older adults. METHODS: A total of 4756 older adults (53.3% women, mean age 71.9 years) met the entry criteria for this study. We measured monthly incident disability, defined as the onset of being certified for personal support or care as required by Japanese public long-term care insurance during the preceding 24 months. Sleep duration, excessive daytime sleepiness (EDS), and demographic factors were assessed at baseline. Cox's proportional hazard regression analysis estimated hazard ratios (HRs) and 95% confidence intervals (CIs) of incidence of disability according to the 3 categories of sleep duration (short: </=6.0 hours, mid: 6.1 to 8.9 hours, long: >/=9.0 hours), and we used mid duration sleepers as the reference group. RESULTS: Long sleep duration (HR 1.43, 95% CI 1.04-1.97) and presence of EDS (HR 1.41, 95% CI 1.01-1.98) were associated with higher rates of incident disability. Furthermore, a combination of sleep duration and EDS was associated with a higher rate of incident disability than the mid and no EDS group (HR 2.25, 95% CI 1.36-3.70). CONCLUSION: Long sleep duration and EDS affected the incident of disability; thus, older adults with both sleep patterns may require an intervention to alter their sleep habit.

    Dual-task gait performance is impaired in older adults with mild cognitive impairment, but the brain substrates associated with dual-task gait performance are not well-established. The relationship between gray matter and gait speed under single-task and dual-task conditions (walking while counting backward) was examined in 560 seniors with mild cognitive impairment (non-amnestic mild cognitive impairment: n = 270; mean age = 72.4 yrs., 63.6 % women; amnestic mild cognitive impairment: n = 290; mean age = 73.4 yrs., 45.4 % women). Multivariate covariance-based analyses of magnetic resonance imaging data, adjusted for potential confounders including single-task gait speed, were performed to identify gray matter patterns associated with dual-task gait speed. There were no differences in gait speed or cognitive performance during dual-task gait between individuals with non-amnestic mild cognitive impairment and amnestic mild cognitive impairment. Overall, increased dual-task gait speed was associated with a gray matter pattern of increased volume in medial frontal gyrus, superior frontal gyrus, anterior cingulate, cingulate, precuneus, fusiform gyrus, middle occipital gyrus, inferior temporal gyrus and middle temporal gyrus. The relationship between dual-task gait speed and brain substrates also differed by mild cognitive impairment subtype. Our study revealed a pattern of gray matter regions associated with dual-task performance. Although dual-task gait performance was similar in amnestic and non-amnestic mild cognitive impairment, the gray matter patterns associated with dual-task gait performance differed by mild cognitive impairment subtype. These findings suggest that the brain substrates supporting dual-task gait performance in amnestic and non-amnestic subtypes are different, and consequently may respond differently to interventions, or require different interventions.

    The effects of exercise and physical activity on cognitive function and brain health have been established by longitudinal and intervention studies. However, it is not clear whether exercise has positive effects on cognitive function in older adults with mild cognitive impairment. Further studies, including a ramdomized controlled trial with a larger sample size, are required to identify the effects of exercise and multicomponent intervention on cognitive function in the older adults with mild cognitive impairment. It is also important to identify the adequate duration, frequency, and intensity of exercise intervention that is most effective for older individuals.

    AIM: The aim of the present study was to evaluate the relationship between sedentary time and declines in kidney function among community-dwelling older adults. METHODS: Participants comprised 10 242 community-dwelling older adults who were participating in the National Center for Geriatrics and Gerontology - Study of Geriatric Syndromes. Sedentary time was determined by asking participants to record the total amount of hours usually spent sitting each day, with values divided into quartiles of 0 to <4 h (reference), 4 to <6 h, 6 to <8 h and ≥8 h of sitting time per day. The estimated glomerular filtration rate was determined according to creatinine levels, and participants were classified into two categories: ≥60.0 or <60 mL/min/1.73 m2 . RESULTS: After multivariate adjustment, the highest quartiles of sedentary time showed a higher rate of kidney function decline than those in the lowest quartile (odds ratio 1.42, 95% CI 1.02-1.37). In addition, participants with a history of cancer (odds ratio 1.18, 95% CI 1.01-1.39) or hypertension (odds ratio 1.38; 95% CI 1.07-1.60) had significantly increased risks of kidney function decline in the highest sedentary time group, regardless of multivariate control. Furthermore, analyses showed an increased risk of kidney function decline for a history of both cancer and hypertension (odds ratio 2.02, 95% CI 1.08-3.80). CONCLUSIONS: A higher level of sedentary time was associated with kidney function decline among community-dwelling older adults. Geriatr Gerontol Int 2017; 17: 730-736.

    BACKGROUND: Memory impairment is considered a hallmark of amnestic mild cognitive impairment (aMCI) and dementia. Emerging evidence suggests that the prefrontal lobe is required to maintain memory functions. The purpose of this study was to clarify whether older adults with aMCI have decreased prefrontal oxygenation during memory encoding and retrieval compared with age-matched healthy older adults, using multi-channel near-infrared spectroscopy. METHODS: We examined 64 older adults with aMCI (mean 71.8 years) and 66 cognitively healthy control subjects comparable in age and gender (mean 71.7 years). The concentration of oxy-hemoglobin, which is a reliable biomarker of changes in regional cerebral blood flow, was measured in the prefrontal cortex during encoding and delayed retrieval of a list of 10 target words. Task performance was evaluated as average number of correct answers in the retrieval task. RESULTS: Subjects with aMCI showed reduced activation in the bilateral dorsolateral cortex (approximately Brodmann area 9) and provided fewer correct answers in the retrieval period than control subjects. There were no significant differences during encoding. CONCLUSIONS: Reduced activation in the dorsolateral cortex during retrieval may cause deficits in memory performance, which may be used as a marker of aMCI. Further studies are required to examine the predictive validity of this decreased activation pattern for the incidence of Alzheimer's disease.

    BACKGROUND: Disability is a crucial health problem in aging. Identifying a biological contributory factor would be useful. Serum insulin-like growth factor-1 (IGF-1) plays an important role in the endocrine system and is associated with frailty. However, there is no consensus about the relationship between IGF-1 and disability. This study aimed to examine whether IGF-1 related to incident disability among older adults. METHODS: The study included 4,133 older adults (mean age, 71.8+/-5.4 years) who were participants in the "Obu Study of Health Promotion for the Elderly" cohort study. We collected information on demographic variables, measured gait speed, Mini Mental State Examination score, and serum IGF-1 at baseline. During follow-up, incident disability was monitored by Long-Term Care Insurance certification. RESULTS: Disability was observed in 212 participants during a mean follow-up duration period of 29.2 months. A log rank test indicated that lower levels of serum IGF-1 were related to incident disability (p = .004). A Cox hazard regression showed a lower quartile in IGF-1 related to disability compared with the highest quartile (Q4), even when adjusting for covariates including gait speed and Mini Mental State Examination score (Q1: hazard ratio = 1.72, 95% confidence intervals: 1.06-2.81; Q2: hazard ratio = 1.64, 95% confidence intervals: 0.99-2.71; Q3: hazard ratio = 1.31, 95% confidence intervals: 0.76-2.25). In the analysis, stratified by sex, there was also significant relationship between IGF-1 and disability among women, but not men. CONCLUSIONS: Lower serum IGF-1 was independently related to disability among older adults.

    AIM: Self-reported exhaustion (SE) is a clinical complaint that is associated with a wide range of chronic diseases. However, the association of SE with physical activity, physical function or cognitive function among the older adult Japanese population is unclear. The present study aimed to determine the prevalence of SE, as well as whether physical function, cognitive function and physical activity were significant covariates. METHODS: A total of 4607 adults (mean age 71 years) were considered eligible for participation based on the study criteria. SE was evaluated using the Study of Osteoporotic Fracture Index. We also evaluated physical activity, physical function (grip strength, Timed Up & Go) and cognitive function (Mini-Mental State Examination, Trail Making Test part A and B, Symbol Digit Substitution Task). RESULTS: The prevalence of SE ranged from 40.9% to 55.0%, and significantly increased with age. The results of the multiple logistic regression analyses showed that in the adjusted model of the 65-69 years age group, physical activity, Timed Up & Go and Symbol Digit Substitution Task were independently associated with SE. In the 70-79 years age group, physical activity, Timed Up & Go, Trail Making Test part A and B and Symbol Digit Substitution Task were independently associated with exhaustion. Only physical activity was associated with exhaustion in the >/=80 years age group. CONCLUSIONS: The prevalence of SE increased with age in the older adult Japanese population. Exhaustion was strongly associated with reduced daily physical activity, especially in those aged >/=80 years. Further studies should be carried out to determine if physical activity causes SE.

    AIM: Cognitive impairment can negatively affect driving performance and increase the risk of driving errors, leading to vehicle crashes. We used a population-based survey to identify the prevalence of cognitive impairments in older drivers. METHODS: A total of 10,073 older adults were enrolled in the National Center for Geriatrics and Gerontology - Study of Geriatric Syndromes. We characterized general cognitive impairment using the Mini-Mental State Examination (MMSE). We also used the National Center for Geriatrics and Gerontology-Functional Assessment Tool, which includes six tasks to assess word list memory, logical memory, attention and executive function, processing speed, and visuospatial skill. RESULTS: Just 15% of older women with moderate cognitive decline (MMSE </=20) drove, whereas 61% of older men with moderate cognitive decline drove. Cognitively normal participants (MMSE score 27 and over) scored significantly better on six cognitive tests compared with those with mild (MMSE score 21-26) or moderate cognitive decline, and those in the mild cognitive decline group scored significantly better on six cognitive tests than those in the moderate cognitive decline group. CONCLUSION: A total of 61% of older men with moderate cognitive decline did not cease driving. These older drivers showed poor cognitive performance in multiple domains compared with those with normal and mild cognitive decline. Further studies are required to clarify the relationships between cognitive decline and car crashes in these high-risk populations.

    OBJECTIVES: This study examined the predictive validity of flanker tasks on driving cessation in older drivers. The flanker task comprises a set of response inhibition tests used to assess the ability to suppress responses. METHODS: A total of 2805 older drivers aged >/=65 years at baseline participated in this study. We conducted several baseline assessments focused on physical and psychological health as well as cognitive performance. Fifteen months after the baseline measurements, we collected information about the current driving status of the participants. RESULTS: Forty-eight participants (1.7%) ceased driving during the 15-month period following the assessment. Logistic regression models identified the following as significant predictors of driving cessation: performance on the trail-making test (parts A and B), digit symbol substitution test scores, story memory, and flanker task scores for the total, congruent, and incongruent conditions. The flanker task scores for the total, congruent, and incongruent conditions were significant predictors in the fully adjusted logistic model. CONCLUSION: The flanker task was more important than assessments of general cognition, including memory, attention, executive control, and processing speed, in predicting driving cessation. The flanker task may be useful for identifying driving cessation in older adults.

    OBJECTIVES: To elucidate whether a combination of slow gait speed and depressive symptoms result in higher risk of incident disability in older adults than either symptom individually. DESIGN: Prospective cohort study. SETTING: Obu City, Aichi Prefecture, Japan. PARTICIPANTS: Participants were 4038 older adults (48.7% male, mean age = 71 years) who met the study inclusion criteria. MEASUREMENTS: Longitudinal data on incident disability were collected up to 33 months [median 31 months (interquartile range 29-32 months)] after baseline. We monitored monthly incident disability, defined as Japanese long-term care insurance certification for personal support or care. Baseline measurements included covariates for incident disability, gait speed, and the Geriatric Depression Scale for assessing depressive symptoms. The associations between slow gait, depressive symptoms, or their co-occurrence, and incident disability were examined. RESULTS: Control participants were the reference in an adjusted Cox proportional hazard regression model. Participants with co-occurring slow gait and depressive symptoms showed a greater risk of incident disability [hazard ratio (HR) 3.08, confidence interval (CI) 95% 2.00-4.75]. Greater risk was also found for participants with slow gait speed alone (HR 2.44, CI 95% 1.71-3.47) and depressive symptoms alone (HR 1.60, CI 95% 1.01-2.53). CONCLUSIONS: Older adults with both risk factors may require early detection and physical and psychological intervention.

    AIMS: Identifying the risk factors of cognitive impairment is essential for implementing effective prevention strategies for dementia. Previous studies have shown that the frequency of going outdoors is inversely associated with cognitive decline. Little research has examined whether the relationship between going outdoors and cognitive decline varies with physical functioning in older adults. The aim of the present study was to examine the relationship between going outdoors and cognitive function in older adults with and without physical function limitations. METHODS: The present study analyzed the data of 4450 individuals (aged 65 years or older) who participated in the Obu Study of Health Promotion for the Elderly. The measures were the Mini-Mental State Examination (MMSE), going outdoors (at least once a week or not), self-reported physical function limitations (with or without), and demographic and health-related factors as potential confounders. RESULTS: Analysis of covariance and post-hoc comparisons showed that although going outdoors at least once a week was associated with higher MMSE scores among older adults with limited physical function, it was not significantly associated with the MMSE scores among older adults without limited physical function. Similarly, logistic regression analyses, stratified by physical function, showed a significant association between going outdoors and MMSE (<24 points or not) among older adults with limited physical function. CONCLUSIONS: The results show that going outdoors less than once a week is associated with decreased cognitive function among older adults with limited physical function, but it is not associated with cognitive function among older adults without limited physical function.

    The prevalence of disability is increasing due to an expanding aging population and an increasing incidence of chronic health problems. Cognitive impairment may predict the development of disability in older adults. Therefore, we examined the association of mild cognitive impairment (MCI) and/or general cognitive impairment (GCI, defined as a Mini Mental State Examination [MMSE] score of 20-23) with the development of disability in a cohort of Japanese community-dwelling older adults. A total of 4290 participants (aged >/=65 years) enrolled in the Obu Study of Health Promotion for the Elderly were classified according to the presence and degree of cognitive impairment as follows: cognitively healthy, GCI, MCI single domain (MCIs), MCIs with GCI, MCI multiple domain (MCIm), and MCIm with GCI. MMSE scores, risk factors for dementia, and incidences of new disability were recorded. After an average of 29.5 months, 205 participants (4.8%) experienced a new onset of disability. All subtypes of cognitive impairment showed significant relationships with disability except for GCI alone. The following hazard ratios (HRs) were determined: MCIs (HR, 2.04; 95% CI, 1.39-3.00), MCIs with GCI (HR, 2.10; 95% CI, 1.21-3.62), MCIm (HR, 2.32; 95% CI, 1.39-3.85), and MCIm with GCI (HR, 4.23; 95% CI, 2.73-6.57). These results indicate that cognitive impairment may be related to an increased risk for the development of disability. Healthcare providers should implement global cognitive assessments to identify MCI and GCI and consider preventive interventions for disability, especially in older persons.

    OBJECTIVES: To identify the relationships between physical and/or cognitive frailty and instrumental activities of daily living (IADL) functioning in community living older persons. DESIGN: Cross sectional observation study. SETTING: Data extracted from the 2011-2013 of the National Center for Geriatrics and Gerontology-Study of Geriatric Syndromes (NCGG-SGS) database. PARTICIPANTS: A total of 8,864 older adults aged >/= 65 years who were enrolled in the NCGG-SGS. MEASUREMENTS: We characterized physical frailty as limitations in three or more of the following five domains: slow walking speed, muscle weakness, exhaustion, low activity and weight loss. To screen for cognitive impairment, we used the National Center for Geriatrics and Gerontology-Functional Assessment Tool (NCGG-FAT) which included tests of word list memory, attention and executive function (tablet version of the Trail Making Test, part A and B), and processing speed (tablet version of the Digit Symbol Substitution Test). Two or more cognitive impairments indicated by an age-adjusted score of at least 1.5 standard deviations below the reference threshold was characterized as cognitive impairment. Each participant reported on their IADL status (use of public transportation, shopping, management of finances, and housekeeping) and several potential confounders such as demographic characteristics. RESULTS: The overall prevalence of physical frailty, cognitive impairment, and cognitive frailty, i.e. co-occurrence of frailty and cognitive impairment, was 7.2%, 5.2%, and 1.2%, respectively. We found significant relationships between IADL limitations and physical frailty (Odds Ratio (OR) 1.24, 95% confidence interval (95% CI) 1.01 to 1.52), cognitive impairment (OR 1.71, 95% CI 1.39 to 2.11), and cognitive frailty (OR 2.63, 95% CI 1.74 to 3.97). CONCLUSION: Using the NCGG-SGS frailty criteria, we found more participants with physical frailty than with cognitive frailty. The individuals with cognitive frailty had the highest risks of IADL limitations. Future investigation is necessary to determine whether this population is at increased risk for incidence of disability or mortality.

    BACKGROUND: Many studies have examined the negative social and health consequences of driving cessation in later life. However, whether the transition to driving cessation results in the incidence of functional limitation in older people remains unclear. OBJECTIVE: The aim of this study was to examine whether driving cessation was associated with the incidence of functional limitation in older Japanese individuals. METHODS: The study included 3,556 participants (mean age: 71.5 +/- 5.3 years, 50.2% women) enrolled in the 'Obu Study of Health Promotion for the Elderly' cohort study between August 2011 and February 2012. The participants were classified into three groups according to their driving status: driving, driving cessation, and nondriving. We assessed new incidence of functional limitation over a 24- month period and examined several confounding factors. RESULTS: The incidence rates for functional limitation in the driving, driving cessation, and nondriving groups were 0.9, 10.8, and 5.6%, respectively (p < 0.001). The fully adjusted Cox proportional hazard model showed that hazard ratios (HRs) for functional limitation in nondrivers [HR: 2.37, 95% confidence interval (CI): 1.27-4.44] and those who had ceased driving (HR: 7.80, 95% CI: 2.61-23.36) were significantly higher relative to those observed in current drivers. CONCLUSION: Driving cessation exerted a strong impact on the risk of functional limitation. Further study is required to determine appropriate intervention strategies to help older people to maintain the abilities required for safe driving and delay the functional limitation associated with driving cessation.

    OBJECTIVES: Mild cognitive impairment (MCI) may be a risk for disability, and co-occurrence of slow gait (SG) and MCI may increase this risk. DESIGN: Prospective study. SETTING: General community. PARTICIPANTS: The study included 3482 older adults (mean age: 71.4 years) without disability at baseline. MEASUREMENTS: We collected information on demographic variables, measured gait speed and cognitive function to diagnose MCI at baseline. During the follow-up period, the incident disability was monitored. Participants were divided into groups without MCI and SG (control), with SG without MCI (SG), without SG and with MCI in single (sMCI) or multiple (mMCI) domains, and with SG and MCI in single (sMCI + SG) and multiple (mMCI + SG) domains. RESULTS: During follow-up, 134 participants developed disability (mean follow-up: 29.4 months). The proportions of incident disability were higher in the MCI with SG, MCI, and SG groups, compared with the control group. SG [hazard ratio 2.27 (95% confidence interval: 1.38-3.73)], mMCI [2.56 (1.31-5.02)], sMCI + SG [2.46 (1.21-5.00)], and mMCI + SG [3.48 (1.79-6.76)] participants had risks for disability. CONCLUSIONS: Co-occurrence of SG and MCI in multiple domains has a higher risk of disability than each condition alone.

    OBJECTIVES: The aim of this study was to determine whether mild cognitive impairment (MCI) affects the development of fear of falling (FoF) in older adults. DESIGN: Prospective cohort study. SETTING: The Obu Study for Health Promotion in the Elderly, Japan. PARTICIPANTS: A total of 1700 community-dwelling people aged 65 years or older without FoF at baseline participated. MEASUREMENTS: FoF and related variables, such as physical function, self-rated health, depression, and total number of medication doses, were investigated at baseline. Participants also underwent cognitive tests and were divided into cognitive healthy and MCI. Fifteen months after the baseline measurements, we collected information about the status of FoF and fall incidence during the 15-month follow-up. RESULTS: At the 15-month follow-up survey, 452 participants (26.5%) reported the development of FoF. Logistic regression analysis showed that MCI (odds ratio [95% CI] = 1.41 [1.07-1.87]) and a fall incident (3.00 [2.23-4.07]) during follow-up independently predicted the development of FoF, after controlling for demographic factors, physical function, self-rated health, and depression. The odds ratio for the development of FoF in participants with both MCI and a fall incident compared with those without them was 7.34 (4.06-13.3), after controlling for confounding factors. CONCLUSION: MCI predicts the new onset of FoF in older adults, especially when they have experience with falling. Aside from the risk of falling, it is suggested that individuals with MCI are an at-risk population for FoF and related negative consequences in terms of postfall syndrome.

    The linkage between gait and cognition has been shown in cases of white matter lesion (WML) that affect gait in older adults. Dual-task walking is believed to be cognitively demanding and to alter trunk movement, and gait impairment in people with mild cognitive impairment (MCI) is highlighted under this condition. However, the association between dual-task walking and structural changes in the brain, particularly with WML, in people with MCI is still unclear. The aim of this study was to examine the association between trunk stability during dual-task walking and WML in 560 older adults with MCI. We measured magnetic resonance imaging (MRI) and gait variables. Gait variables included harmonic ratio in vertical, mediolateral, and anteroposterior directions, analyzed using a tri-axial accelerometer attached to the lower trunk. Walking conditions were normal walking and dual-task walking (counting backwards while walking) conditions. Demographical data and brain atrophy were measured as covariates. Subjects were classified into non-severe WML (n = 451, mean age = 73.2 years) and severe WML (n = 109, mean age = 75.9 years) groups. Linear mixed-effects model analysis controlled for covariates showed dual-task-related changes in all harmonic ratios associated with WML (p < 0.05). Even after adjustment for executive function, harmonic ratio in the mediolateral direction was significantly associated with WML (p < 0.05). Our findings revealed that WMLs were associated with trunk stability in dual-task walking. Further studies are required to investigate the neural basis for deficits in gait ability among MCI subjects.

    OBJECTIVES: Motoric cognitive syndrome (MCR), a newly described predementia syndrome characterized by cognitive complaints and slow gait, is associated with increased risk of developing dementia. Due to the potential differences in health, behavioral, and lifestyle factors between races that can influence dementia risk, it is important to examine risk factors for MCR in different countries. This study aimed to report the prevalence as well as modifiable factors associated with MCR in Japanese community-dwelling older adults. DESIGN: A cross-sectional design. SETTING: General community. PARTICIPANTS: A total of 9683 older adults (52% women, mean age: 73.6 years) participating in the National Center for Geriatrics and Gerontology Study of Geriatric Syndromes. MEASUREMENTS: Participants were screened for presence of MCR at baseline. The association of selected modifiable risk factors (medical illness, depressive symptoms, and falls) and lifestyle variables (obesity, physical inactivity, smoking, and alcohol consumption) with MCR was examined using multivariate logistic regression analysis. RESULTS: At cross-section, 619 participants met criteria for MCR, with an overall prevalence 6.4% (95% CI 5.9-6.9). A higher prevalence of MCR was seen with advancing age (P < .001), but there were no sex differences. Diabetes (adjusted odds ratio [OR] 1.47, P = .001), depressive symptoms (OR 3.57, P < .001), and falls (OR 1.45, P < .001) were associated with increased risk of MCR. Among the lifestyle factors, obesity (OR 1.26, P = .018) and physical inactivity (OR 1.57, P < .001) were associated with increased risk of MCR. CONCLUSION: MCR is common in the elderly Japanese population. The potentially modifiable risk and lifestyle factors identified for MCR should be further studied to develop interventions.

    BACKGROUND: Depressive symptoms and memory problems are significant risk factors for dementia. Exercise can reduce depressive symptoms and improve cognitive function in older people. In addition, the benefits of horticultural activity on physical and mental well-being have been demonstrated in people with dementia. Although evidence of such non-pharmacological interventions is mounting, no studies have examined whether physical exercise and horticultural activity exert a positive impact on brain and mental health (e.g., depressive symptoms) in non-demented older adults at high risk of cognitive impairment and depression. Therefore, we propose a randomized controlled trial to assess the efficacy and efficiency of physical exercise and horticultural activity in improving brain and mental health in community-dwelling older adults with memory problems and depressive symptoms. METHODS/DESIGN: The 20-week randomized controlled trial will include 90 community-dwelling adults aged 65 years or older with memory problems and depressive symptoms. Participants will be randomized to one of three experiments: exercise, horticultural activity, or educational control group, using a 1:1:1 allocation ratio. The combined exercise program and horticultural activity program will consist of 20 weekly 90-minute sessions. Participants in the exercise group will practice aerobic exercise, muscle strength training, postural balance retraining, and dual-task training. The horticultural activity program will include crop-related activities, such as field cultivation, growing, and harvesting. Participants in the educational control group will attend two 90-minute educational classes during the 6-month trial period. Depressive symptoms and memory performance will be measured by the Geriatric Depression Scale-15, and the Logical Memory subtests of the Wechsler Memory Scale-Revised will be used to measure depressive symptoms and memory performance as primary outcomes, at baseline (prior to randomization), immediately following intervention (6 months from baseline), and 6 months after intervention. Hippocampal volume will be measured at baseline and immediately after intervention, using magnetic resonance imaging. Secondary outcomes will comprise cognitive function, including language, attention/executive performance, and processing speed; brain-derived neurotrophic-factor serum levels; and health-related quality of life. DISCUSSION: This intervention study will determine the clinical importance and efficacy of physical exercise and horticultural activity as non-pharmacological interventions in community-dwelling older adults at high risk of poor brain and mental health.

    OBJECTIVE: To determine social frailty status using simple questions and to examine the association between social frailty and disability onset among community-dwelling older adults. DESIGN: Prospective cohort study. SETTING: Japanese community. PARTICIPANTS: A total of 4304 adults age >/=65 years living in the community participated in a baseline assessment from 2011 to 2012. They were followed monthly for incident certification of care needs during the 2 years after the baseline assessment. MEASUREMENTS: Care-needs certification in the national long-term care insurance system of Japan; a self-reported questionnaire including 7 items to define social frailty status, adjustment for several potential confounders such as demographic characteristics; and Kaplan-Meier survival curves for disability incidence by social frailty. RESULTS: During the 2 years, 144 participants (3.3%) were certified as requiring long-term care insurance in accordance with incident disability. Five of the 7 items in the self-reported questionnaire were significantly associated with disability incidence. In the adjusted model including potential covariates, participants who were defined as having social frailty (>/=2/5) (hazard ratio 1.66, 95% confidence interval 1.00-2.74) and prefrailty (=1/5) (hazard ratio 1.53, 95% confidence interval 1.02-2.531), based on 5 items at the baseline assessment, had an increased risk of disability compared with nonfrail participants (=0/5). CONCLUSIONS: Social frailty, assessed using simple questions regarding living alone, going out less frequently compared with the prior year, visiting friends sometimes, feeling helpful to friends or family, and talking with someone every day, has a strong impact on the risk of future disability among community-dwelling older people.

    OBJECTIVE: To examine the relationship between physical frailty and risk of disability, and to identify the component(s) of frailty with the most impact on disability in community-dwelling older adults. DESIGN: Prospective cohort study. SETTING: A Japanese community. PARTICIPANTS: 4341 older adults aged >/=65 living in the community participated in a baseline assessment from 2011 to 2012 and were followed for 2 years. MAIN OUTCOME MEASURES: Care-needs certification in the national long-term care insurance (LTCI) system of Japan, type of physical frailty (robust, prefrail, frail) and subitems (slowness, weakness, exhaustion, low activity, weight loss), adjusted for several potential confounders such as demographic characteristics, analysed with Kaplan-Meier survival curves for incidence of disability by frailty phenotype. RESULTS: During the 2-year follow-up period, 168 participants (3.9%) began using the LTCI system for incidence of disability. Participants classified as frail (HR 4.65, 95% CI 2.63 to 8.22) or prefrail (2.52, 1.56 to 4.07) at the baseline assessment had an increased risk of disability incidence compared with robust participants. Analyses for subitems of frailty showed that slowness (2.32, 1.62 to 3.33), weakness (1.90, 1.35 to 2.68) and weight loss (1.61, 1.13 to 2.31) were related to increased risk of disability incidence. In stratified analyses, participants who were classified as frail and who had lower cognitive function had the highest percentage (30.3%) of disability incidence during the 2 years after baseline assessment. CONCLUSIONS: Physical frailty, even being prefrail, had a strong impact on the risk of future disability. Some components of frailty, such as slowness, weakness and weight loss, are strongly associated with incident disability in community-dwelling older adults.

    BACKGROUND/AIMS: An understanding of the association between gray matter volume and executive functioning could provide strategies to reduce dementia risk in older people with mild cognitive impairment (MCI). METHODS: In a cross-sectional analysis, we assessed executive functioning in 83 older people with MCI using three standard neuropsychological tests: set shifting (difference between Trail Making Test Parts B and A), working memory (difference between Digit Span forward and backward from the Wechsler Adult Intelligence Scale-IV), and selective attention/response inhibition (difference between the second and third conditions of the color- and picture-word Stroop test). Gray matter volume was computed from brain MRIs and SIENAX from FSL software. RESULTS: Gray matter volume was significantly associated with set-shifting performance after accounting for age, gender, body mass index, education, and global cognition (standardized beta = -0.376, p = 0.001), but not with working memory or selective attention/response inhibition. CONCLUSION: The executive function of set-shifting ability was correlated with gray matter volume in older people with MCI.

    OBJECTIVE: To identify the differences of incidence of disability between frail older persons with and without slow walking speed. DESIGN: Prospective cohort study. SETTING: Japanese community. PARTICIPANTS: A total of l4,081 older adults aged >/=65 years living in the community, participated in a baseline assessment and were followed for incidence of disability for 29.5 months. MEASUREMENTS: Care-needs certification in the national long-term care insurance system of Japan, physical frailty (slow walking speed, muscle weakness, exhaustion, low activity, weight loss), adjusted for several potential confounders such as demographic characteristics; Kaplan-Meier survival curves for incident disability by physical frailty with and without slow walking speed. RESULTS: During the follow-up period, 198 participants (4.9%) were certified as requiring long-term care insurance in accordance with incident disability. Participants who had prefrailty without slow walking speed (hazard ratio 1.86, 95% confidence interval 1.19-2.92), prefrailty with slow walking speed (3.62, 2.19-5.96), frailty without slow walking speed (4.33, 2.00-9.39), and frailty with slow walking speed (4.68, 2.72-8.05) at the baseline assessment had an increased risk of incident disability compared with nonfrail participants. In stratified analyses, frail older men and frail participants with low cognitive performance had the highest risk of incidence of disability. CONCLUSION: The presence of frailty or even prefrailty when older adults showed slow walking speed increased the risk of future disability in community-dwelling older adults.

    AIM: To examine the association of the combination of slow gait and mild cognitive impairment (MCI) with cognitive function and falling in community-dwelling older people. METHODS: Participants were selected from the Obu Study of Health Promotion for the Elderly (n = 3400), and underwent gait examination and a battery of neuropsychological examinations, including the Mini-Mental State Examination and the National Center for Geriatrics and Gerontology Functional Assessment Tool (tablet version of Trail Making Test Part A and B, Symbol Digit Substitution Task, Figure selection task, Word memory and Story memory), and were interviewed with a series of questionnaires including medical history, physical activity, geriatric depression scale and fall history. RESULTS: Participants were classified into control (n = 2281), slow gait speed (SG; n = 278), MCI (n = 673) and MCI with SG (MCI+SG; n = 168) groups. All cognitive functions were significantly affected by the group factor, even adjusting for participant characteristics as covariates (P < 0.001). Post-hoc analysis showed that the control group had better performance than the other groups, and the MCI+SG group had worse performance than the other groups in all cognitive functions (all P < 0.05). In multiple logistic regression analysis, SG and MCI were independently associated with falling (all P < 0.05), and MCI+SG had a higher odds ratio for falling (adjusted OR 1.99, 95% CI 1.08-3.65). CONCLUSIONS: Our findings support the idea that slow gait and MCI were related, and concurrently associated with falling. Motor function among MCI subjects should be focused on to assess profile risks.

    OBJECTIVE: To examine the relationships between smoking status and various domains of cognitive function in community-dwelling elderly subjects. METHODS: Participants (N = 4348) were asked about smoking status, demographic variables, and lifestyle factors, and underwent multidimensional neurocognitive tests. RESULTS: All analyses were conducted separately by sex. Women never smokers exhibited significantly better scores than past and/or current smokers in some neurocognitive tests. Among men, never smokers had significantly higher scores, such as in the Symbol Digit Substitution Test. Multiple linear regression analysis showed that pack-years (history of smoking) were significantly associated with the Symbol Digit Substitution Test in men. CONCLUSIONS: Smoking status may be associated with a decline in processing speed, and this decline varies by sex.

    AIM: Mild cognitive impairment (MCI) is conceptualized as prodromal of Alzheimer's disease (AD). Declined physical function is one of the risk factors for progression to AD, whereas genetic factors, especially the apolipoprotein E epsilon4 allele (APOE4), also contribute to the risk of AD and affect the risk factors. However, the association between APOE4 and physical function in MCI is still unclear. To elucidate the association, we carried out the present study to compare physical function between APOE4 carriers and non-carriers in MCI. METHODS: The study included 386 MCI patients (mean age 71.6 years) who were classified into APOE4 carrier and non-carrier groups. The participants' characteristics were assessed by face-to-face interviews. Grip strength, five chair stand test, walking speed and 6-min walking test were measured as physical functions. RESULTS: In univariate analysis, the APOE4 carrier group had decreased walking speed compared with the non-carrier group (P < 0.05), but other measures of physical function were not significantly different between the groups. The linear regression model showed a significant association between walking speed and APOE4 after adjusting for covariates (P < 0.05). CONCLUSIONS: The present study showed that APOE4 carrier participants with MCI had decreased walking speed compared with non-carrier participants. Thus, APOE4 genotypes should be considered as a potential mediator when the measure of walking speed is used as a risk factor of dementia in older adults with MCI. Further studies using prospective data are required to clarify the relationship between physical function and genetic factors in MCI.

MEASUREMENTS: The estimated glomerular filtration rate (eGFR, mL/min/1.73 m(2)) was determined according to the creatinine level, and participants were classified into three mutually exclusive categories: normal (>/=60.0 mL/min/1.73 m(2)), mild CKD (45.0-59.9 mL/min/1.73 m(2)), or moderate to severe CKD (<45.0 mL/min/1.73 m(2)). Cognitive function was assessed using the National Center for Geriatrics and Gerontology-Functional Assessment Tool. Multivariate logistic regression was used to examine the relationships between eGFR and cognitive decline. RESULTS: After multivariate adjustment, participants with lower eGFR had lower cognitive function scores on most domains (P < .05). In particular, participants with advanced CKD (eGFR <45 mL/min/1.73 m(2)) were more likely to have significant cognitive decline on the Trail Making Test part A (odds ratio = 2.347, 95% confidence interval = 1.525-3.614) and the Symbol Digit Substitution Task (odds ratio = 2.308, 95% confidence interval = 1.486-3.585) than those with normal and mild CKD. CONCLUSIONS: A lower level of kidney function was associated with lower cognitive performance in attention and processing speed. These results suggest that eGFR might be an effective method to screen for cognitive decline in community-dwelling older adults.

    OBJECTIVE: To examine whether the Berg Balance Scale (BBS) score on admission and after 1 month can be used to predict the Functional Independence Measure (FIM) walking level 6 or 7 (modified independent and independent gait respectively) after 3 months and to determine the optimal BBS cut-off score for predicting independent gait among inpatients with first stroke in a rehabilitation facility. DESIGN: Retrospective cohort study. SETTING: Inpatient rehabilitation facility (Kaifukuki). PARTICIPANTS: Two hundred fifty-one consecutive patients with first stroke and nonindependent gait on admission. OUTCOME MEASURES: BBS on admission and after 1 month and FIM on admission and after 3 months. RESULTS: Area under the receiver operating characteristic curves for predicting independent gait after 3 months were 0.81 (95% confidence interval [CI], 0.75-0.88) for BBS score on admission; the optimal cut-off score being >/=13 (63% sensitivity; 90% specificity). Achieving greater cut-off score on admission was significantly associated with subsequent independent gait (odds ratio, 9.7; 95% CI, 4.38-21.36; P < .001). A subanalysis of patients with poor balance on admission (BBS score <13; n = 191) showed area under the receiver operating characteristic curves for predicting independent gait after 3 months of 0.88 (95% CI, 0.80-0.95) for BBS scores 1 month after admission. In this subgroup, BBS scores at 1 month of >/=27 were significantly associated with subsequent independent gait (odds ratio, 21.6, 95% CI, 6.40-73.20; P < .001). CONCLUSIONS: Admission BBS scores predicted FIM walking level 6 or 7, which denotes modified independent or independent gait, after 3 months, the optimal cut-off for BBS scores being >/=13 among inpatients with first stroke in a rehabilitation facility. Patients with poor balance on admission whose BBS scores had improved to >/=27 at 1 month after admission were likely to achieve modified independent or independent gait within 3 months after admission.

    BACKGROUND: Greater physical activity (PA) is associated with better memory performance and greater hippocampal volume in older adults. However, most studies to date assessed PA via questionnaires and thereby lacked objective characterization of PA (eg, intensity, duration, etc.). Thus, we currently do not have a comprehensive understanding of PA characteristics that are important for neuroprotection, especially among older adults with mild cognitive impairment (MCI). Thus, using triaxial accelerometers, we examined the association between light- and moderate-intensity PA, total duration of PA, hippocampal volume, and memory in older adults with MCI. METHODS: This cross-sectional study involved 310 older adults with MCI who completed neuropsychological tests of memory, and structural magnetic resonance imaging. Participants were instructed to wear the accelerometer on an elastic band on their hip at all times for 2 weeks. Average daily duration of light, moderate, and total PA (min/day) was calculated. RESULTS: Moderate PA was associated with hippocampal volume (beta = .167, p = .003) after controlling for age, but light PA (beta = -.021, p = .713) and total PA (beta = .011, p = .844) were not. Both light and moderate PAs were not associated with memory performance. Structural equation modeling demonstrated that moderate PA was not directly associated with memory but significantly contributed to hippocampal volume; hippocampal volume loss was significantly and directly associated with poor memory performance. CONCLUSIONS: Our results suggest that the benefits of moderate PA on memory among older adults with MCI are mediated by hippocampal volume. Furthermore, light PA may not reduce dementia risk among older adults with MCI.

    Our aim was to determine whether baseline measures of cognitive functioning, walking speed, and depressive status are independent predictors of limitations in instrumental activities of daily living (IADL) in older adults. The cross-sectional study involved 1329 community-dwelling adults, aged 75 years or older. At baseline, the Mini-Mental State Examination (MMSE), Symbol Digit Substitution Test (SDST), Geriatric Depressive Scale (GDS), and a word list memory task were completed, and self-reported IADLs and walking speed were recorded. The longitudinal study involved 948 participants without baseline IADL limitation, which was assessed at baseline and 15-month follow up, using the three Kihon Checklist subitems. In cross-sectional analyses, participants with IADL limitation demonstrated greater GDS scores, slower walking speeds, and lower MMSE, word list memory task, and SDST (only for women) scores relative to those without IADL limitation. In the longitudinal analyses, baseline walking speed (men: OR 0.98; women: OR 0.97, p<0.05) and word list memory task scores (men: OR 0.84; women: OR 0.83, p<0.05) in both sexes and SDST scores in women (OR 0.96, p=0.04) were independent predictors of subsequent IADL limitation. Walking speed, memory, and processing speed may be independent predictors of IADL limitation in older adults.

    OBJECTIVE: The purpose of this study was to determine whether frailty is an important and independent predictor of incident depressive symptoms in elderly people without depressive symptoms at baseline. DESIGN: Fifteen-month prospective study. SETTING: General community in Japan. PARTICIPANTS: A total of 3025 community-dwelling elderly people aged 65 years or over without depressive symptoms at baseline. MEASUREMENTS: The self-rated 15-item Geriatric Depression Scale was used to assess symptoms of depression with a score of 6 or more at baseline and 15-month follow-up. Participants underwent a structural interview designed to obtain demographic factors and frailty status, and completed cognitive testing with the Mini-Mental State Examination and physical performance testing with the Short Physical Performance Battery as potential predictors. RESULTS: At a 15-month follow-up survey, 226 participants (7.5%) reported the development of depressive symptoms. We found that frailty and poor self-rated general health (adjusted odds ratio 1.86, 95% confidence interval 1.30-2.66, P < .01) were independent predictors of incident depressive symptoms. The odds ratio for depressive symptoms in participants with frailty compared with robust participants was 1.86 (95% confidence interval 1.05-3.28, P = .03) after adjusting for demographic factors, self-rated general health, behavior, living arrangements, Mini-Mental State Examination, Short Physical Performance Battery, and Geriatric Depression Scale scores at baseline. CONCLUSIONS: Our findings suggested that frailty and poor self-rated general health were independent predictors of depressive symptoms in community-dwelling elderly people.

    The decrease in serum insulin-like growth factor-1 (IGF-I) with aging is related to the neurobiological processes in Alzheimer's disease. IGF-1 mediates effects of physical exercise on the brain, and cognition has a common pathophysiology with physical function, particularly with gait. The aim of this study was to examine whether mild cognitive impairment (MCI) and slow gait are associated with the serum IGF-1 level. A population survey was conducted in 3355 participants (mean age, 71.4 years). Cognitive functions (attention, executive function, processing speed, visuospatial skill, and memory), gait speed, and demographic variables were measured. All cognitive functions and gait speed were associated with the IGF-1 level (p < 0.001). The association of IGF-1 with slow gait was weakened by adjustment for covariates, but MCI and the combination of MCI and slow gait were independently related to the IGF-1 level in multivariate analysis (p < 0.05). Our findings support the association of a low IGF-1 level with reduced cognitive function and gait speed, particularly with a combination of MCI and slow gait.

    Physical activity may help to prevent or delay brain atrophy. Numerous studies have shown associations between physical activity and age-related changes in the brain. However, most of these studies involved self-reported physical activity, not objectively measured physical activity. Therefore, the aim of this study was to examine the association between objectively measured physical activity, as determined using accelerometers, and brain magnetic resonance imaging (MRI) measures in older adults with mild cognitive impairment (MCI). We analyzed 323 older subjects with MCI (mean age 71.4 years) who were recruited from the participants of the Obu Study of Health Promotion for the Elderly. We recorded demographic data and measured physical activity using a tri-axial accelerometer. Physical activity was classified as light-intensity physical activity (LPA) or moderate-to-vigorous physical activity (MVPA). Brain atrophy and the severity of white matter lesions (WML) were determined by MRI. Low levels of LPA and MVPA were associated with severe WML. Subjects with severe WML were older, had lower mobility, and had greater brain atrophy than subjects with mild WML (all P<0.05). Multivariate analysis revealed that more MVPA was associated with less brain atrophy, even after adjustment for WML (beta=-0.126, P=0.015), but LPA was not (beta=-0.102, P=0.136). Our study revealed that objectively measured physical activity, especially MVPA, was associated with brain atrophy in MCI subjects, even after adjusting for WML. These findings support the hypothesis that physical activity plays a crucial role in maintaining brain health.

    OBJECTIVE: The aim of this cross-sectional study was to determine the associations between self-reported subjective physical and cognitive age, and actual physical and cognitive functions among community-dwelling older people aged 75 years and older. METHOD: The sample comprised 275 older adults aged 75-91 years. Two questions were asked regarding subjective age: 'How old do you feel physically?' and 'How old do you feel cognitively?' To assess physical functions, we measured handgrip strength, knee extension strength, standing balance and walking speed. Tests of attention, executive function, processing speed and memory were performed to assess actual cognitive function. RESULTS: Subjective physical and cognitive age was associated with performance on all of the physical and cognitive tests, respectively (p < 0.01). We also found that older adults who reported themselves as feeling older than their chronological age had a slower walking speed and lower scores for word-list memory recall than those who did not report themselves as feeling older than their actual age. CONCLUSION: These findings suggest that promoting a fast walking speed and good memory function may help to maintain a younger subjective physical and cognitive age in older adults aged 75 years and older.

    [Purpose] Older adults experience exhaustion-induced health problems, such as poor physical function and low physical activity levels. The associations between self-reported exhaustion and physical function and activity are not clear in older adults with mild cognitive impairment (MCI). The aim of this study was to investigate the relationships between self-reported exhaustion and physical function and activity in older adults with mild cognitive impairment. [Subjects] A total of 356 older adults with mild cognitive impairment (mean age = 71.6 +/- 0.3 years, 50.8% women) were included in this study. [Methods] Self-reported exhaustion was identified by one item from the Study of Osteoporotic Fractures index. Gait speed, gait endurance, and life space were also assessed. [Results] Sixty-two participants reported having exhaustion, giving a 17.4% prevalence of self-reported exhaustion among these individuals. Logistic regression analysis showed that the Life-Space Assessment score was the only parameter significantly independently associated with exhaustion status (adjusted odds ratio 0.97, 95% confidence interval 0.95-0.99). [Conclusion] These results suggest that self-reported exhaustion is associated with life space. Future research is needed to identify ways for older people with MCI to improve their exhaustion status.

    Many longitudinal studies have found that older adults with depressive symptoms or depression have increased risk of cognitive impairment. We investigated the relationships between depressive symptoms or depression, cognitive function, serum brain-derived neurotrophic factor (BDNF), and volumetric MRI measurements in older adults. A total of 4352 individuals aged 65 years or older (mean age 72 years) participated in the study. We investigated medical history and geriatric depression scale-15 (GDS-15) items to determine depression and depressive symptoms. Cognitive tests included the mini-mental state examination (MMSE), story memory, word list memory, trail-making tests, and the symbol digit substitution task. Of the 4352 participants, 570 (13%) fulfilled the criteria for depressive symptoms (GDS-15: 6 + points) and 87 (2%) were diagnosed with depression. All cognitive tests showed significant differences between the 'no depressive symptoms', 'depressive symptoms', and 'depression' groups. The 'depressive symptoms' and 'depression' groups showed lower serum BDNF (p < 0.001) concentrations than the 'no depressive symptoms' group. The 'depressive symptoms' group exhibited greater atrophy of the right medial temporal lobe than did the 'no depressive symptoms' group (p = 0.023). These results suggest that memory, executive function, and processing speed examinations are useful to identify cognitive decline in older adults who have depressive symptoms and depression. Serum BDNF concentration and atrophy of the right medial temporal lobe may in part mediate the relationships between depressive symptoms and cognitive decline.

    Growing evidence supports the relationships between depressive symptoms, cognitive decline, and brain structural changes in older adults. The purpose of this study was to determine whether depressive symptoms are related to cerebral oxygenation during cognitive tasks in older adults. In this study, 80 elderly subjects (73.9 +/- 5.4 years, 34 males) were evaluated using multi-channel Near-infrared spectroscopy. Concentration changes (mmolcm/l) in oxy-hemoglobin (oxy-Hb), as the most reliable available indicator of changes in regional cerebral blood flow, in the right and left prefrontal cortex were measured during the Trail Making Test Part B (TMT-B). Depressive symptoms were assessed using the short Geriatric Depression Scale (GDS). Subjects were divided into a depressive group (GDS greater than or equal to 6) and non-depressive group (GDS lower than 6). In results, Oxy-Hb activation during the TMT-B was significantly smaller in the depressive group (n=13) than in the non-depressive group (n=67) in both the right and left prefrontal cortex. In the multivariate analysis, GDS scores were significantly negatively correlated with oxy-Hb activation after adjusting for age, gender and educational history (right, beta=-0.32, p=0.002; left, beta=-0.25, p=0.02). Less prefrontal activation in older adults with depressive symptoms may account for decline in executive function. Further studies are needed to investigate the influence of the less brain activation associated with depressive symptoms on future cognitive decline and structural brain changes in older adults.

    The purpose of this study was to examine whether the combined factors of physical performance, depressive symptoms and cognitive status are significantly associated with a history of falling in community-dwelling elderly. We performed a cross-sectional community-based survey, the OSHPE, from August 2011 to February 2012. In total, 5104 community-dwelling older adults aged 65 years and older (mean age 72.0) participated in the OSHPE. Participants underwent a grip strength (GS) test, chair stand test (CST), Timed Up & Go (TUG) test, Geriatric Depression Scale (GDS), and Mini-Mental State Examination (MMSE). Of the 4481 participants who met our requirements, 645 (14.4%) participants reported falling at least once in the past year. In a signal detection analysis (SDA), we found that the combination of GDS (>/=6 points) and TUG (>/=10.6 s) had the highest fall rate (36.4%), and the combination of GDS (<6 points) and CST (<11.1 s) had the lowest fall rate (11.7%). The highest fall rate group had a significantly higher odds ratio (OR) compared with the lowest fall rate group after adjusting for other potentially confounding variables [OR 3.12 (95% confidence interval (CI) 2.08-4.68) p<0.001]. The combination of depressive symptoms, TUG, and CST performance was strongly associated with a history of falling in community-dwelling elderly.

    OBJECTIVES: Few studies have reported the relationship between fear of falling (FoF) and mild and global cognitive impairment in community-dwelling older adults. We aimed to determine whether the status of cognitive impairment affects the prevalence of FoF in community-dwelling older adults. STUDY DESIGN: Cross-sectional study among 4474 community-dwelling older adults who participated in the Obu Study of Health Promotion for the Elderly. MAIN OUTCOME MEASURES: Participants underwent cognitive tests and were divided into three groups: cognitive healthy, mild cognitive impairment (MCI), and global cognitive impairment (GCI). FoF and related variables, such as fall history, physical function, and depression, were also investigated. RESULTS: The prevalence of FoF was significantly different by group (p<0.001; healthy: 43.6%, MCI: 50.6%, GCI: 40.6%). Logistic regression analysis showed that GCI (odds ratio=0.63; 95% confidence interval=0.526-0.76) was independently associated with FoF, after controlling for confounding factors. Older adults with GCI showed the lowest prevalence of FoF, although they had the lowest physical function comparing with the other groups (p<0.001). CONCLUSION: MCI and GCI in community-dwelling older adults affect the prevalence of FoF in a completely different manner. Further study is required to determine whether insensitivity to FoF with GCI increases the risk of falling in older adults.

    BACKGROUND: Gait ability and cognitive function are interrelated during both normal walking (NW) and dual-task walking (DTW), and gait ability is thus adversely affected by cognitive impairment in both situations. However, this association is insufficiently understood in people with mild cognitive impairment (MCI). Here, we conducted a study with MCI participants, to examine whether the association depends on walking conditions and MCI subtypes. METHODS: We classified 389 elderly adults into amnestic MCI (n = 191) and non-amnestic MCI (n = 198), assessed their cognitive functions, and administered gait experiments under NW and DTW conditions. Gait ability was defined as gait speed. Five aspects of cognitive function were assessed: processing speed, executive function, working memory, verbal memory, and visual memory. RESULTS: Regression analysis adjusted for covariates showed a significant association between cognitive functions and gait speed. Processing speed and executive function correlated with gait speed during both NW and DTW (p < .05). Gait speed during DTW was also significantly associated with working memory (p < .001). Visual memory was associated during NW and DTW, particularly for amnestic MCI participants (p < .05). CONCLUSIONS: Our findings support the idea that the association between gait speed and cognitive function depends on walking condition and MCI subtypes. Additional studies are necessary to determine the neural basis for the disruption in gait control in older adults with MCI.

    AIM: Several operative definitions and screening methods for sarcopenia have been proposed in previous studies; however, the opinions of researchers still differ. We compared the prevalence of sarcopenia using two different algorithms: (i) the European working group on sarcopenia in older people (EWGSOP)-suggested algorithm using gait speed as the first step; and (ii) the muscle mass and strength algorithm. METHODS: A population-based, cross-sectional survey of adults aged over 65 years was carried out. Data on a total of 4811 participants were available for analysis. Gait speed, grip strength and appendicular skeletal muscle mass were assessed to determine sarcopenia. Appendicular skeletal muscle mass was estimated from bioimpedance analysis measurements and expressed as skeletal muscle mass index. Grip strength and skeletal muscle mass index were considered to be low if they fell below the threshold of the lowest 20% of values measured in a subset of healthy subjects. We compared the prevalence rates of sarcopenia determined by the two algorithms. RESULTS: The prevalence rate of sarcopenia in a representative sample of older Japanese adults was 8.2% for men and 6.8% for women based on the EWGSOP algorithm. The two algorithms identified the same participants as sarcopenic, the only difference being the EWGSOP algorithm classified an additional seven participants (0.15%) into sarcopenia compared with the muscle mass and strength algorithm. CONCLUSION: It is debatable whether inclusion of gait speed is necessary when screening for sarcopenia in community-dwelling older adults. Future research should examine the necessity of including gait speed in algorithms and the validity of cut-off values.

    Olfactory impairment constitutes one of the earliest signs of Alzheimer's disease in older adults with mild cognitive impairment. We investigated which aspects of neuropsychological measures are correlated with olfactory identification performance among older adults with mild cognitive impairment. Total of 220 participants with mild cognitive impairment (mean age 71.7 years) were examined. Odor identification was assessed using the Open Essence test. Participants underwent comprehensive neurocognitive evaluation, including measures of verbal memory, visual memory, working memory, attention/executive function, and processing speed. We examined associations between olfactory function and cognitive performance scores. Participants with severe hyposmia exhibited significantly poor verbal and visual memory performance, attention/executive function, and slower processing speed scores compared with those without severe hyposmia. In multivariable logistic regression models, better performance scores on verbal and visual memory were significantly associated with decreased likelihood of severe hyposmia after adjusting for age, sex, education, and other cognitive performance scores. These findings suggest that olfactory impairment might be more closely associated with memory loss compared with other aspects of cognitive functioning in mild cognitive impairment subjects.

    OBJECTIVE: The clinical relationship between brain-derived neurotrophic factor (BDNF) and cognitive function or mild cognitive impairment (MCI) is not well-understood. The purpose of this study was to identify the relationship between serum BDNF and cognitive function and MCI, and determine whether serum BDNF level might be a useful biomarker for assessing risk for MCI in older people. MATERIALS AND METHODS: A total of 4463 individuals aged 65 years or older (mean age 72 years) participating in the study. We measured performance in a battery of neuropsychological and cognitive function tests; serum BDNF concentration. RESULTS: Eight hundred twenty-seven participants (18.8%) had MCI. After adjustment for sex, age, education level, diabetes, and current smoking, serum BDNF was associated with poorer performance in the story memory, and digit symbol substitution task scores. Serum BDNF was marginally associated with the presence of MCI (odds ratio, 95% confidence interval: 1.41, 1.00-1.99) when BDNF was 1.5 SD lower than the mean value standardized for sex and age, education level, diabetes, and current smoking. CONCLUSION: Low serum BDNF was associated with lower cognitive test scores and MCI. Future prospective studies should establish the discriminative value of serum BDNF for the risk of MCI.

    AIM: This study sought to confirm the test-retest reliability and validity of the National Center for Geriatrics and Gerontology functional assessment tool (NCGG-FAT), a newly developed assessment of multidimensional neurocognitive function using a tablet personal computer (PC). METHODS: This study included 20 community-dwelling older adults (9 females, aged 65-81 years). Participants were administered the NCGG-FAT twice, separated by approximately 30 days to determine test-retest reliability. To test the validity of the measure, participants underwent established neurocognitive measurements, including memory, attention, executive function, processing speed and visuospatial function within a week from the first administration of the NCGG-FAT. RESULTS: Test-retest reliability was in an acceptable range for each component of the NCGG-FAT, with intraclass correlation coefficients ranging from 0.764 to 0.942. Each task in the NCGG-FAT showed a moderate to high correlation with scores on widely-used conventional neurocognitive tests (r = 0.496 to 0.842). CONCLUSION: We found that the NCGG-FAT using a tablet PC was reliable in a sample of community-dwelling older adults. The NCGG-FAT might be useful for cognitive screening in population-based samples and outcomes, enabling assessment of the effects of intervention on multidimensional cognitive function among older adults.

    BACKGROUND AND AIMS: Dual-task walking (DTW) is thought to involve activation of the prefrontal cortex in healthy adults and to be affected by cognitive impairment. However, it is unclear whether prefrontal cortex activation is involved in DTW in older adults with mild cognitive impairment. This study examined brain activation during DTW among older adults with mild cognitive impairment using functional near-infrared spectroscopy. METHODS: Sixteen older adults (aged 75.4 +/- 7.2 years, women n = 6) performed gait experiments under normal walking and DTW conditions. We used a design with 60-s blocks consisting of a 10-s rest standing as pre-resting period, a 20-s walking task period, and a 30-s rest standing as post-resting period. Walking speed was measured during a 20-s walking task. Changes in oxy-hemoglobin were measured in the prefrontal area during gait experiments. RESULTS: Walking speed was slower during DTW compared with normal walking (p < 0.001). The oxy-hemoglobin level during DTW was higher than during normal walking (p < 0.001) and was correlated with executive function, as measured by Stroop interference (p < 0.05). CONCLUSION: Our findings indicate that DTW is associated with prefrontal activation among older adults with mild cognitive impairment. The brain activation during DTW was correlated with executive function. Additional studies are necessary to elucidate the effects of cognitive impairment on the association between prefrontal activity and walking under various conditions.

    BACKGROUND: The risk of falling is associated with cognitive dysfunction. Older adults with mild cognitive impairment (MCI) exhibit an accelerated reduction of brain volume, and face an increased risk of falling. The current study examined the relationship between baseline physical performance, baseline gray matter volume and falls during a 12-month follow-up period among community-dwelling older adults with MCI. METHODS: Forty-two older adults with MCI (75.6 years, 43% women) underwent structural magnetic resonance imaging and baseline physical performance assessment, including knee-extension strength, one-legged standing time, and walking speed with normal pace. 'Fallers' were defined as people who had one or more falls during the 12-month follow-up period. RESULTS: Of the 42 participants, 26.2% (n = 11) experienced at least one fall during the 12-month follow-up period. Fallers exhibited slower walking speed and shorter one-legged standing time compared with non-fallers (both p < .01). One-legged standing time (sec) (standardized odds ratio [95% confidence interval]: 0.89 [0.81, 0.98], p = .02) was associated with a significantly lower rate of falls during the 12-month follow-up after adjusting for age, sex, body mass index, and history of falling in the past year at baseline. Voxel-based morphometry was used to examine differences in baseline gray matter volume between fallers and non-fallers, revealing that fallers exhibited a significantly greater reduction in the bilateral middle frontal gyrus and superior frontal gyrus. CONCLUSIONS: Poor balance predicts falls over 12 months, and baseline lower gray matter densities in the middle frontal gyrus and superior frontal gyrus were associated with falls in older adults with MCI. Maintaining physical function, especially balance, and brain structural changes through many sorts of prevention strategies in the early stage of cognitive decline may contribute to decreasing the risk of falls in older adults with MCI.

    OBJECTIVE: Preventive strategies for frailty and mild cognitive impairment (MCI) are important for avoiding future functional decline and dementia in older adults. The purpose of this study was to use a population-based survey to ascertain the single and combined prevalence of frailty and MCI and to identify the relationships between frailty and MCI in older Japanese adults. DESIGN: Cross-sectional study. SETTING: General community. PARTICIPANTS: A total of 5104 older adults (aged 65 years or older, mean age 71 years) who were enrolled in the Obu Study of Health Promotion for the Elderly (OSHPE). MEASUREMENTS: Each participant underwent detailed physical and cognitive testing to assess frailty and MCI. We considered the frailty phenotype to be characterized by limitations in 3 or more of the following 5 domains: mobility, strength, endurance, physical activity, and nutrition. Screening for MCI included a standardized personal interview, the Mini-Mental State Examination, and the National Center for Geriatrics and Gerontology-Functional Assessment Tool (NCGG-FAT), which included 8 tasks used to assess logical memory (immediate and delayed recognition), word list memory (immediate and delayed recall), attention and executive function (tablet version of Trail Making Test-part A and B), processing speed (tablet version of digit symbol substitution test), and visuospatial skill (figure selection). RESULTS: The overall prevalence of frailty, MCI, and frailty and MCI combined was 11.3%, 18.8%, and 2.7%, respectively. We found significant relationships between frailty and MCI (the odds ratio adjusted for age, sex, and education was 2.0 (95% confidence interval 1.5-2.5). CONCLUSIONS: Using the OSHPE criteria, we found more participants with MCI than with frailty. The prevalence of frailty and MCI combined was 2.7% in our population. Future investigation is necessary to determine whether this population is at increased risk for disability or mortality.

    This study evaluated brain activity during unaccustomed treadmill walking using positron emission tomography (PET) and [(18)F]fluorodeoxyglucose. Twenty-four healthy elderly females (75-82 years) participated in this study. Two PET scans were performed after 25 min of rest and after walking for 25 min at 2.0 km/h on a treadmill. Participants were divided into low and high step-length variability groups according to the median coefficient of variation in step length during treadmill walking. We compared the regional changes in brain glucose metabolism between the two groups. The most prominent relative activations during treadmill walking compared to rest in both groups were found in the primary sensorimotor areas, occipital lobe, and anterior and posterior lobe of the cerebellum. The high step-length variability group showed significant relative deactivations in the frontal lobe and the inferior temporal gyrus during treadmill walking. There was a significant relative activation of the primary sensorimotor area in the low step-length variability group compared to the high step-length variability group (P = 0.022). Compared to the low step-length variability group, the high step-length variability group exhibited a greater relative deactivation in the white matter of the middle and superior temporal gyrus (P = 0.032) and hippocampus (P = 0.034) during treadmill walking compared to resting. These results suggest that activation of the primary sensorimotor area, prefrontal area, and temporal lobe, especially the hippocampus, is associated with gait adaptability during unaccustomed treadmill walking.

    AIM: The aim of this study was to examine the relationship between dual-task performance and neurocognitive measures in community-dwelling older people with mild cognitive impairment (MCI). METHODS: A total of 98 subjects (mean age 74.8 years, 52.0% female) participated in the study. We compared 36 participants with amnestic MCI (aMCI) with 62 participants with non-amnestic MCI (non-aMCI) on dual-task performance as measured by reaction time responses. The relationships between dual-task performance and multiple domains of neurocognitive functions, including general cognitive function, visual memory, working memory, executive function and processing speed, were examined. RESULTS: Although there were no statistically significant group differences in simple reaction times (P = 0.734), the aMCI group showed significantly slower dual-task reaction times than the non-aMCI group (P = 0.012). Using multiple regression analysis, we found that there was a significant relationship between executive function and dual-task reaction times (beta = 0.298, P = 0.006). CONCLUSION: These results showed that aMCI subjects showed a specific deficit in dual-task performance compared with non-aMCI subjects, and poor dual-task performance was associated with declines in executive function in older people with MCI. Future longitudinal and interventional studies should investigate the use of dual-task testing with varying levels of cognitive demand in older adults at risk of dementia.

    AIM: The detection of the early stages in amnesic mild cognitive impairment (aMCI) is considered important in diagnosing progression to Alzheimer's disease. The current study sought to investigate differences in cognitive function between control subjects with no memory loss (control), and subjects in the early stage of aMCI (EMCI) and late stage of aMCI (LMCI). METHODS: A total of 100 community-dwelling older adults aged 65 years and over were recruited from 1543 potential subjects. Subjects were classified into three groups based on the degree of objective memory impairment; control (n=29), EMCI (n=34) and LMCI (n=37). Multiple neuropsychological tests were carried out to examine cognitive function. RESULTS: The EMCI individuals showed lower cognitive function relative to controls; not only in logical memory, but also in letter fluency (P<0.05). There were no significant differences in neuropsychological scores between the EMCI and LMCI groups, except for category fluency and logical memory. In addition, the EMCI subjects' logical memory score showed a significant relationship with letter fluency, category fluency and digit span backward test performance (P<0.05). CONCLUSIONS: These results suggest that the application of multiple neuropsychological tests might be useful in diagnosing older adults with EMCI and LMCI.

    Exercise training has been shown to increase physical function in the elderly. However, the effects of exercise on elderly individuals with amnestic aMCI are unclear. The aim of this RCT was to investigate the effect of multicomponent exercise on gait in the elderly. Fifty elderly individuals with aMCI (age: 65-92 years) participated in the study and were randomly allocated to a multicomponent exercise or control group. Multicomponent exercise training was performed for 90 min, twice a week over six months. Gait was analyzed at baseline and after the six month intervention. Gait analysis was performed on an eleven meter walkway at each subject's comfortable walking speed. A miniature tri-axial accelerometer was attached to the L3 spinous process and was used to analyze gait speed, stride length, stride time, and the harmonic ratio (HR) (representing the smoothness of trunk movement). There were no differences in the participant characteristics or gait parameters between the groups at baseline. After adjustment for covariates the multicomponent exercise program had a significant (p<0.05) effect on gait speed, stride length, and the vertical HR. Through improving gait, multicomponent exercise training improves the physical health of the elderly with aMCI.

    This study sought to investigate the relationship between going outdoor daily and prefrontal cortex activation during execution of the VFT using near-infrared spectroscopy (NIRS) in community-dwelling older adults. Blood oxygenation changes in left and right prefrontal cortices were measured in twenty older adults (mean age 76.1 +/- 6.7 years) by NIRS during VFT performance. In this task, participants were required to pronounce as many nouns as possible beginning with the letters "Shi," "I," and "Re." Changes in oxygenated hemoglobin (oxy-Hb) levels during the VFT were compared between two groups defined by the frequency of going outdoors: daily or non-daily within a week. Participants in both groups exhibited significantly increased oxy-Hb levels in the left and right prefrontal cortices during the VFT compared to a resting baseline condition. After controlling for age and gender, there were significant group-by-condition interactions on oxy-Hb levels with less activation during the execution of the VFT over both cortices in the non-daily group (left: F=4.76, p=0.04; right: F=6.32, p=0.02). These findings indicate that going outdoors daily is associated with increased activation in the prefrontal cortices during VFT performance in community-dwelling older adults.

    AIM: Restriction of life-space is associated with physical performance and functional decline in older adults. Little is known about the factors associated with life-space in older adults with amnestic mild cognitive impairment (aMCI). The purpose of this study was to identify factors associated with life-space in older adults with aMCI. METHODS: The study participants were 69 older adults (mean age 74.5 years, males 56.5%) who were identified with aMCI. Life-space mobility was measured using a Japanese translation of the life-space assessment (LSA). Age, sex, cognitive function (general function, executive function and processing speed), physical performance, instrumental activities of daily living status (IADL) and fear of falling (FoF) were measured as potential relevant factors. RESULTS: Univariate analysis showed that the LSA was associated with FoF, sex, physical performance, processing speed and IADL. In the stepwise regression analysis, FoF, processing speed and IADL maintained a significant association with the LSA scores, although sex and physical performance did not reach significance. CONCLUSION: The results suggest that the restrictions of life-space in older adults with aMCI were more affected by the FoF, slower processing speed and restricted IADL than sex or physical performance.

    BACKGROUND: Although much evidence supports the hypothesis that cognitive function and physical function are interrelated, it is unclear whether cognitive decline with mild cognitive impairment influences trainability of physical performance in exercise intervention. The purpose of this study was to examine the association between cognitive function at baseline and change in physical performance after exercise intervention in older adults with mild cognitive impairment. METHODS: Forty-four older adults diagnosed with mild cognitive impairment based on the Peterson criteria (mean age 74.8 years) consented to and completed a 6-month twice weekly exercise intervention. The Timed Up and Go (TUG) test was used as a measure of physical performance. The Mini-Mental State Examination (MMSE), Trail Making Test Part B, Geriatric Depression Scale, baseline muscle strength of knee extension, and attendance rate of intervention, were measured as factors for predicting trainability. RESULTS: In the correlation analysis, the change in TUG showed modest correlations with attendance rate in the exercise program (r = -0.354, P = 0.027) and MMSE at baseline (r = -0.321, P = 0.034). A multiple regression analysis revealed that change in TUG was independently associated with attendance rate (beta = -0.322, P = 0.026) and MMSE score (beta = -0.295, P = 0.041), controlling for age and gender. CONCLUSION: General cognitive function was associated with improvements in physical performance after exercise intervention in subjects with mild cognitive impairment. Further research is needed to examine the effects of exercise programs designed to address cognitive obstacles in older adults with mild cognitive impairment.

    AIMS: This study aimed to identify differences in the implementation of cognitive activities and instrumental activities of daily living (IADLs) between healthy individuals and subjects with mild cognitive impairment (MCI). METHODS: The study included 2,498 cognitively healthy subjects (mean age, 71.2 +/- 5.1 years) and 809 MCI subjects (mean age, 71.8 +/- 5.4 years). The subjects were interviewed regarding their participation in cognitive activities and the implementation of IADLs. RESULTS: We found a significant association between participation in any cognitive activities (p < 0.001), using a bus or a train (p < 0.001), and MCI. After adjusting for covariates, cognitive activity of any type remained significantly associated with MCI (p < 0.005) but not with the implementation of IADLs. CONCLUSIONS: Our study revealed that greater participation in cognitive activity was associated with lower odds of MCI. Participation in cognitive activities may reflect differences between healthy and MCI subjects. To clarify the causal relationship between cognitive activities and MCI, further studies are required.

    BACKGROUND/AIMS: High fitness levels play an important role in maintaining memory function and delaying the progression of structural brain changes in older people at risk of developing dementia. However, it is unclear which specific regions of the brain volume are associated with exercise capacity. We investigated whether exercise capacity, determined by a 6-min walking distance (6MWD), is associated with measures of logical and visual memory and where gray matter regions correlate with exercise capacity in older adults with mild cognitive impairment (MCI). METHODS: Ninety-one community-dwelling older adults with MCI completed a 6-min walking test, structural magnetic resonance imaging scanning, and memory tests. The Wechsler Memory Scale-Revised Logical Memory and Rey-Osterrieth Complex Figure Tests were used to assess logical and visual memory, respectively. RESULTS: The logical and visual memory tests were positively correlated with the 6MWD (p < 0.01). Poor performance in the 6MWD was correlated with a reduced cerebral gray matter volume in the left middle temporal gyrus, middle occipital gyrus, and hippocampus in older adults with MCI. CONCLUSIONS: These results suggest that a better 6MWD performance may be related to better memory function and the maintenance of gray matter volume in older adults with MCI.

    BACKGROUND: To examine the effect of multicomponent exercise program on memory function in older adults with mild cognitive impairment (MCI), and identify biomarkers associated with improvement of cognitive functions. METHODOLOGY/PRINCIPAL FINDINGS: Subjects were 100 older adults (mean age, 75 years) with MCI. The subjects were classified to an amnestic MCI group (n = 50) with neuroimaging measures, and other MCI group (n = 50) before the randomization. Subjects in each group were randomized to either a multicomponent exercise or an education control group using a ratio of 1ratio1. The exercise group exercised for 90 min/d, 2 d/wk, 40 times for 6 months. The exercise program was conducted under multitask conditions to stimulate attention and memory. The control group attended two education classes. A repeated-measures ANOVA revealed that no group x time interactions on the cognitive tests and brain atrophy in MCI patients. A sub-analysis of amnestic MCI patients for group x time interactions revealed that the exercise group exhibited significantly better Mini-Mental State Examination (p = .04) and logical memory scores (p = .04), and reducing whole brain cortical atrophy (p<.05) compared to the control group. Low total cholesterol levels before the intervention were associated with an improvement of logical memory scores (p<.05), and a higher level of brain-derived neurotrophic factor was significantly related to improved ADAS-cog scores (p<.05). CONCLUSIONS/SIGNIFICANCE: The results suggested that an exercise intervention is beneficial for improving logical memory and maintaining general cognitive function and reducing whole brain cortical atrophy in older adults with amnestic MCI. Low total cholesterol and higher brain-derived neurotrophic factor may predict improvement of cognitive functions in older adults with MCI. Further studies are required to determine the positive effects of exercise on cognitive function in older adults with MCI.

PARTICIPANTS: A total of 10 351 individuals aged 65 years or older (6791 with personal care and 3560 without personal care) participated in the study. MEASURES: Physical performance tests included grip strength, the chair stand test, walking speed at a comfortable pace, and the timed up-and-go test. Personal care was defined as participants who had been certified in the national social long-term care insurance in Japan. RESULTS: Individuals who received personal care showed a significantly poorer performance than those without personal care for all physical performance tests (p<0.001). Gait speed was the most useful of the physical performance tests to determine the demand for personal care (receiver operating characteristic curve statistics: men, 0.92; women, 0.94; sensitivity: men, 86; women, 90; specificity: men, 85; women, 85). After adjustment for age, sex, cognitive impairment and other physical tests, all physical performance tests were individually associated with the demand for personal care. A slow gait speed (<1 m/s) was more strongly correlated with the demand for personal care than other performance measures (gait speed OR: 5.9; 95% CI: 5.0 to 6.9). CONCLUSIONS: Clinical tests of physical performance are associated with the demand for personal care in older people. Preventive strategies to maintain physical independence may be required in older adults who show a gait speed slower than 1 m/s. Further research is necessary to confirm these preliminary results.

    BACKGROUND AND AIMS: There has been much interest in exercise interventions as a primary behavioral prevention strategy against cognitive decline. The aim of this study was to evaluate the effect of a multicomponent exercise program on physical and dual-task performances in community-dwelling older adults with amnestic mild cognitive impairment (aMCI). METHODS: Fifty older adults (23 women) with aMCI (mean age, 76 years) were randomized to an intervention (n=25) or a control group (n=25). The intervention group received a multicomponent exercise program for 90 minutes/day, 2 days/week, or 40 times over six months. The multicomponent exercises included aerobic exercise, muscle strength training and postural balance retraining, which was conducted under multi-task conditions to stimulate attention and memory. Participants in the control group attended two health promotion education classes within six months. Physical and dual-task performances were measured before randomization and after six months. Dual-task performances using reaction times with balance and cognitive demands were measured. RESULTS: The improvement effects on dual-task performances with both balance and cognitive demands were not statistically significant: reaction time with balance demand F1,45=3.3, p=0.07, and cognitive demand F1,45=2.6, p=0.12. However, there was a significant group-by-time interaction on maximal walking speed, which decreased significantly in the control group (F1,45=5.9, p=0.02). CONCLUSION: This six-month multicomponent exercise program improved maximal walking speed in older adults with aMCI; however, it did not improve dual-task performances assessed by reaction times.

    UNLABELLED: BACKGROUND: To examine the effects of a multicomponent exercise program on the cognitive function of older adults with amnestic mild cognitive impairment (aMCI). METHODS: DESIGN: Twelve months, randomized controlled trial; SETTING: Community center in Japan; PARTICIPANTS: Fifty older adults (27 men) with aMCI ranging in age from 65 to 93 years (mean age, 75 years); INTERVENTION: Subjects were randomized into either a multicomponent exercise (n = 25) or an education control group (n = 25). Subjects in the multicomponent exercise group exercised under the supervision of physiotherapists for 90 min/d, 2 d/wk, for a total of 80 times over 12 months. The exercises included aerobic exercises, muscle strength training, and postural balance retraining, and were conducted using multiple conditions to stimulate cognitive functions. Subjects in the control group attended three education classes regarding health during the 12-month period. MEASUREMENTS were administered before, after the 6-month, and after the 12-month intervention period; MEASUREMENTS: The performance measures included the mini-mental state examination, logical memory subtest of the Wechsler memory scale-revised, digit symbol coding test, letter and categorical verbal fluency test, and the Stroop color word test. RESULTS: The mean adherence to the exercise program was 79.2%. Improvements of cognitive function following multicomponent exercise were superior at treatment end (group x time interactions for the mini-mental state examination (P = 0.04), logical memory of immediate recall (P = 0.03), and letter verbal fluency test (P = 0.02)). The logical memory of delayed recall, digit symbol coding, and Stroop color word test showed main effects of time, although there were no group x time interactions. CONCLUSIONS: This study indicates that exercise improves or supports, at least partly, cognitive performance in older adults with aMCI.

    BACKGROUND AND AIMS: Many studies have suggested that social network, leisure activity, and physical activity can have protective effects against dementia and Alzheimer's disease. However, previous studies have not examined the relationship between daily activities and brain atrophy in older adults. This study aimed to explore what kind of daily activities were associated with atrophy of the medial temporal area including the entorhinal cortex (MTA-ERC) in older adults. METHODS: In total, 122 older adults (aged 65 and over) with subjective memory complaints or a Clinical Dementia Rating of 0.5 underwent magnetic resonance imaging, and MTA-ERC atrophy was assessed by the voxel- based morphometry method. Based on magnetic resonance imaging data, the subjects were divided into atrophy and non-atrophy groups. Daily activities were assessed using a 20-item questionnaire (e.g., instrumental activities of daily living, social activities), and we compared activity participation between the groups. RESULTS: The atrophy group (n=37) showed significantly lower participation in 4 out of 20 activity items (cleaning, intellectual activity, culture lessons, and using a personal computer) than the non-atrophy group (n=85). Summed scores of these 4 items (range from 0 to 4) were significantly associated with MTA-ERC atrophy even after adjustment for age, sex, education status, and Mini-Mental State Examination score. CONCLUSIONS: In conclusion, MTAERC atrophy was associated with cognitive activities or household-related activities requiring planning.

    BACKGROUND: Dual-task walking is believed to be more cognitively demanding than normal walking and alters trunk movement among older adults. However, the possible association between brain atrophy and spatiotemporal gait parameters, particularly during dual-task walking, is poorly understood. In this study, we examined the relationship between dual-task walking and brain atrophy. METHODS: One hundred ten elderly adults (aged 65-94 years, women n = 55) underwent magnetic resonance imaging scanning and gait experiments under normal and dual-task walking conditions. Linear accelerations of the trunk were measured in vertical, anteroposterior, and mediolateral directions using a triaxial accelerometer attached to the lower trunk. Gait speed, stride length, and cadence were recorded. The harmonic ratio, a measure of trunk stability, was computed separately in each direction to evaluate the smoothness of trunk movement during walking. Brain atrophy was quantitatively assessed using magnetic resonance image data. RESULTS: Gait speed, stride length, cadence, and harmonic ratio in all directions were lower in dual-task walking than in normal walking (p < .05). The dual-task-related changes in harmonic ratio were independently correlated with brain atrophy adjusted for subject characteristics only in the vertical direction (p < .05). CONCLUSIONS: Our findings support the hypothesis that dual-task walking is more cognitively demanding than normal walking. Decreased trunk stability during dual-task walking is associated with brain atrophy. Additional studies are necessary to elucidate the effects of regional brain atrophy on the control of walking.

    AIMS: The purpose of this study is to clarify the effects of exercise intervention on vascular risk factors in older adults with mild cognitive impairment (MCI). METHODS: Community-dwelling older adults who met the definition of MCI using the Petersen criteria (n = 100; mean age = 75.3 years) were randomly allocated to the exercise (n = 50) or education control group (n = 50). Participants in the exercise group exercised under the supervision of physiotherapists for 90 min/day, 2 days/week, 80 times for 12 months. Anthropometric profiles, blood markers, blood pressure, and physical fitness (the 6-min walking test) were measured. Total cholesterol (TC), high-density lipoprotein cholesterol (HDL-C), and TC/HDL-C risk ratio measurements were taken from blood samples. RESULTS: The exercise group showed significantly reduced TC and TC/HDL-C risk ratio after training compared with baseline levels (p < 0.001, p = 0.004). However, no significant reduction was found for the control group (p = 0.09, p = 0.09). Physical fitness also significantly improved after exercise intervention compared with the control group (p < 0.0001). CONCLUSION: Exercise intervention was associated with positive changes in important vascular risk factors related to cognitive decline and vascular disease in older adults with MCI.

    AIM: The current study sought to determine which types of cognitive function are related to atrophy of the bilateral medial temporal areas including the entorhinal cortex (MTA-ERC) in elderly adults. METHODS: The subjects were 96 elderly adults (mean age 75.3 years) with mild cognitive impairment. Subjects underwent Wechsler Memory Scale-Revised, logical memory I and II (WMS-R, LM I and II), Rey complex figure retention tests after 3 and 30 min (RCF-3 min and RCF-30 min), digit span backword (DSB), digit symbol-coding (DSC), Stroop Color and Word Test-Interference List (SCWT-IL) as well as magnetic resonance imaging (MRI) and were divided into elderly adults without or with mild to moderate MTA-ERC atrophy, and those with severe atrophy. RESULTS: In all subjects, MTA-ERC atrophy showed significant relationships with age (r = 0.43), education (r = -0.25), WMS-R, LM I (r = -0.21), DSC (r = -0.32), and SCWT-IL (r = 0.32). The mild to moderate atrophy group showed significant relationships between MTA-ERC atrophy and age (r = 0.34), DSC (r = -0.28), and SCWT-IL (r = 0.25). In contrast, in the severe atrophy group, MTA-ERC atrophy was correlated significantly with RCF-3 min (r = -0.70) and RCF-30 min (r = -0.74). The linear regression model included demographic variables and cognitive tests; two variables to survive the step-wise analysis were age (beta = 0.374) and SCWT-IL (beta = 0.247) in all subjects. Age (beta = 0.301), and RCF-30 min (beta = -0.521) and age (beta = 0.460) remained as a significant variable in the mild to moderate atrophy and severe atrophy groups, respectively. CONCLUSION: Executive function tests such as SCWT-IL may be useful as a screening tool to identify mild to moderate MTA-ERC atrophy and a decline in the RCF test may suggest severe MTA-ERC atrophy in elderly adults with MCI.

    BACKGROUND: In spite of a number of reports about various factors associated with the fear of falling (FoF) among older adults (such as age and physical function), the relationship between FoF and cognitive decline remains unclear. OBJECTIVE: To determine which cognitive function is related with the prevalence of FoF in older adults. METHODS: Participants were 101 older adults (mean age 75.1 years; 48.5% males). Of these, 54 older adults (53.4%) were classified as the fear group on the basis of the presence of FoF. Age, gender, the Timed Up and Go test (TUG), fall history, the Alzheimer's Disease Assessment Scale, the Wechsler Memory Scale-Revised-Logical Memory I (WMS-LM I), the delayed memory test, digit symbol coding, digit span and verbal fluency were measured as potential relevant factors. RESULTS: Logistic regression analysis revealed that TUG [odds ratio (OR) 1.43, 95% confidence interval (CI) 1.12-1.83; p = 0.004], WMS-LM I (OR 1.20, 95% CI 1.07-1.35; p = 0.002) and fall history (OR 4.38, 95% CI 1.53-12.51; p = 0.006) were independently associated with FoF. CONCLUSIONS: The results suggest that a lower prevalence of self-reported FoF is associated with memory decline among older adults. Insensitivity to FoF may be one of the characteristics of psychological change with memory decline.

    AIM: The purpose of this study was to determine the predictors of interruption to living at home as a result of death, hospitalization, or admission to a long-term care facility in frail elderly people enrolled in a home visit rehabilitation service. METHODS: A total of 311 patients entered a home visit rehabilitation service within a study period of 1 September, 2005 to 31 March, 2010, 146 of whom met the criteria to be enrolled in this study and gave consent. Of these, 73 received a continuous home visit rehabilitation service (continuous group) of over 2 years and 73 experienced interruption to this service due to death, hospitalization, or admission to a long-term care facility (interruption group). The following physical, social, and medical factors were recorded and analyzed: age, sex, care level, disease diagnoses, gait disability, cognitive impairment, living with another person and cause of the interruption to the home-visit rehabilitation service. We compared each item between the interruption and continuous groups. Logistic regression analysis was used to identify the significant predictors of interruptions to living at home. RESULTS: Patients in the interruption group demonstrated significantly lower functioning in activities of daily living (ADL), gait ability and lower cognitive status, and higher rates of respiratory diseases and cancer compared with the continuous group. On logistic regression analysis, ADL score (odds ratio [OR]=0.97, p<0.01), and the presence of respiratory diseases (OR=4.35, p=0.04) and cancer (OR=13.46, p<0.01) were significantly associated with interruptions to living at home. CONCLUSIONS: Lower ADL functioning, respiratory diseases and cancer were significant predictors of interruption to living at home in frail elderly adults.

    AIM: The purpose of this study was to examine factors related to fear of falling (FOF) in elderly adults who showed no reduced performance regarding independent instrumental activities of daily living (IADL). METHODS: A total of 119 elderly adults participated in the study (mean age, 75.7+/-7.2 years, women, n=60). We investigated the prevalence of FOF, anamnesis, medications, body pain, and history of falls, the Geriatric Depression Scale, International Physical Activity Questionnaire, Life-Space Assessment (LSA). The Timed Up and Go test (TUG) and one-legged standing time were measured to evaluate physical performance. Participants were divided into elderly adults with FOF (FOF group) and those without FOF (non-FOF group). The unpaired t-test or chi-square test was used for group comparisons. Multiple logistic regression analysis was then performed to examine the factors associated with FOF. RESULTS: The prevalence of FOF was 51.3% overall. The FOF group had a higher prevalence of anamnesis, body pain, and history of falls than the non-FOF group. The FOF group had lower LSA scores, longer durations on the TUG, and shorter durations on the one-legged standing test than the non-FOF group. On multiple logistic regression analysis, LSA (total score, 120 points) was significantly associated with FOF (odds ratio: 0.96, 95% confidence interval=0.93-0.99). CONCLUSION: Fear of falling was significantly associated with life space in community-dwelling elderly adults who showed no reduced performance regarding IADL. In future, it will be necessary to clarify any possible causal relationship by longitudinal investigations.

    OBJECTIVE: To examine whether declining performance in aspects of physical functioning, including lower extremity muscle strength, 1-legged balance, walking speed, and exercise capacity, is associated with atrophy of medial temporal areas in community-dwelling older adults with mild cognitive impairment (MCI). DESIGN: Cross-sectional study. SETTING: General community in Japan. PARTICIPANTS: Community-dwelling older adults 65 years and older with a Clinical Dementia Rating of 0.5 or memory complaints were enrolled in this study. This study examined 34 participants with amnestic MCI (aMCI) and 58 nonamnestic MCI (non-aMCI) participants. INTERVENTIONS: Not applicable. MAIN OUTCOME MEASURES: The following physical performance tests were conducted: muscle strength of knee extension, 1-legged standing time, 5-m walking test, and 6-minute walk test (6MWT). The z scores of the voxel-based specific regional analysis system for Alzheimer's disease were determined to assess the degree of atrophy in the bilateral medial temporal areas including the entorhinal cortex (MTA-ERC). RESULTS: In the aMCI group, 6MWT performance was associated with MTA-ERC atrophy (beta=-.462, P=.014) after controlling for age. In the stepwise multiple regression analyses, 6MWT and body mass index were found to be significant determinants of MTA-ERC atrophy in all participants (R(2)=.275), as well as the aMCI and non-aMCI groups when analyzed separately (R(2)=.418 and R(2)=.216, respectively). CONCLUSIONS: A decline in exercise capacity was found to be more closely associated with atrophy of the MTA-ERC compared with other aspects of physical functioning in older adults with MCI, especially the amnestic type. These findings suggest that it is important for future studies to investigate the effects of increased aerobic activity and improved fitness on brain volume in older adults at risk of developing dementia.

    The purpose of this study was to determine the interrelationships between lower limb muscle performance, balance, gait and falls in older people using structural equation modeling. Study participants were two hundred and thirteen people aged 65 years and older (mean age, 80.0 +/- 7.1 years), who used day-care services in Japan. The outcome measures were the history of falls three months retrospectively and physical risk factors for falling, including performance in the chair stand test (CST), one-leg standing test (OLS), tandem walk test, 6m walking time, and the timed up-and-go (TUG) test. Thirty-nine (18.3%) of the 213 participants had fallen at least one or more times during the preceding 3 months. The fall group had significantly slower 6m walking speed and took significantly longer to undertake the TUG test than the non-fall group. In a structural equation model, performance in the CST contributed significantly to gait function, and low gait function was significantly and directly associated with falls in older people. This suggests that task-specific strength exercise as well as general mobility retraining should be important components of exercise programs designed to reduce falls in older people.

    BACKGROUND AND AIMS: Many older people fall when they perform tasks which require increased attention. The aim of this study was to determine differences in reaction times, during simple-, dual- and triple-task conditions requiring differing levels of motor coordination, balance control and cognitive attention, between groups of fallers and non-fallers in community-dwelling older individuals. METHODS: The study involved the recruitment of 87 older individuals living at home, 57 women and 30 men aged 75 to 91 years. Reaction times, measured by pushing a handheld button as quickly as possible in response to a visual stimulus, were measured in four conditions: 1) quiet standing (simple-task); 2) counting backward during quiet standing (dual-task with cognitive demand); 3) stepping in place (dual-task with balance demand); and 4) counting backward while stepping in place (triple-task with cognitive and balance demands). RESULTS: Twenty-nine (33.3%) participants had fallen at least once during the past year. There were no statistically significant differences in reaction times between non-fallers and fallers during any of the tasks. Reaction times were significantly longer during the dual- and triple-tasks compared with the simple-task conditions in both groups. The ratio between reaction times during dual-tasks with balance demands (stepping in place) and those in the simple-task condition were significantly related to a history of falls and showed the highest odds ratio (OR 3.16, 95% CI 1.06- 9.45, p=0.04). CONCLUSIONS: Relative changes in reaction times during a dual-task with balance demands were related to a history of falls in community-dwelling older individuals. Reaction times in dual-task conditions with a balance demand were more sensitive to past falls than those during a dual-task with cognitive demands.

    AIM: To investigate the incidence of falls and fall-related fractures in disabled elderly people utilizing long-term care insurance, and influence of gender, age, disabled level is examined. METHODS: Subjects were 8,335 elderly people (mean age, 82.2+/-7.4 years). Falls and fractures were investigated retrospectively for the one year study period either via a self-report questionnaire, or via care workers and/or family members when the subjects had cognitive impairments. The care workers gave are a free description about for the fall that had occurred when using the facilities. RESULTS: Men showed significantly higher rate of falls (26.8%) than women (24.6%). In women, there was a significant difference in fall rates between the severely disabled group (26.4%) and the moderately disabled group (23.5%). Women showed a significantly higher rate of fractures (12.2%) than that of men (4.5%). In relationship between fall-related fractures and potential correlates, there was a significant relation between women and the fall-related fractures [OR 2.5, 95%CI 1.7-3.6]. The severely disabled group showed a significantly higher rate of falls in the toilet, on the other hand, the moderately disabled group showed significantly higher rate of falls during exercise and recreation or standing. CONCLUSION: The rate of falls in women was lower than men in this study population. The result may be affected by the lower proportion of women in the moderately disabled group compared with men. Only gender was significantly associated with the incidence of fall-related fractures in disabled elderly people.

    BACKGROUND: It is argued that a multidimensional approach is necessary for burden assessment. Reducing caregiver burden is a social problem in the ageing Japan society. We examined the combined effect of factors affecting the care burden among community-dwelling handicapped people and their caregivers. METHODS: The participants were 49 handicapped people (aged 53-104 years) who received home-visit rehabilitation, and their 49 caregivers (age 42-85 years). Caregivers were provided questionnaires consisting of questions on social support, subjective well-being, self-efficacy with regard to care continuation, the Motor Fitness Scale and caregiver burden. Care recipients were assessed using the Bedside Mobility Scale and the Barthel Index. RESULTS: We prepared the hypothesis model using structural equation modeling with the bootstrap method within outcome measures. The hypothesis model did not fit the data well. The impact of the Motor Fitness Scale was shifted from the caregiver burden to care self-efficacy and well-being, having a cooperator for care and variable of spouse caregiver or others associated with caregiver well-being in the revised model. The fit of the revised model was acceptable (goodness of fit index, 0.903; comparative fit index, 0.998; root mean square error of approximation, 0.017). In the revised model, the care recipients' disabled state was associated with caregiver burden. In addition, higher burden and poor motor fitness of caregivers might lead to lower care self-efficacy in providing continuous care and lower caregiver well-being. CONCLUSION: These findings suggested that the program to reduce caregiver burden should focus on aspects of the care recipients' disabled state, the caregivers' well-being, fitness, and care self-efficacy.

    AIM: This study examined the factors associated with burdens on the primary caregivers of community-dwelling disabled people. METHODS: Participants were 78 disabled people (40 men, 38 women; mean age 77.8+/-11.5 years) who received home-based physical therapy and/or occupational therapy, and their 78 caregivers (20 men, 58 women; mean age 66.8+/-10.2 years). The caregiver burden was assessed using the short version of the Japanese version of the Zarit Caregiver Burden Interview (J-ZBI_8). In addition, the primary caregivers completed questionnaires about burdens arising from supporting the activities of daily living (ADL) using a visual analogue scale, available social support, subjective well-being, and the Motor Fitness Scale. The performance of the disabled subjects was assessed using the Bedside Mobility Scale and the Barthel Index. The disabled subjects and the caregivers were divided into higher burden (J-ZBI_8 score, 10 points and over) and lower burden groups (J-ZBI_8 score, 9 points and under) to compare the group differences in the measurements. RESULTS: The disabled participants in the lower burden group (n=41) showed significantly higher Bedside Mobility Scale scores and Barthel Index scores than those in the higher burden group (n=37). The primary caregivers in the higher burden group showed significantly higher burden due to supporting the ADL, lower subjective well-being, and lower social support as compared to those in the lower-burden group. CONCLUSION: The burden levels of the primary caregivers relating to the mobility and ADL of their recipients were assessed. The caregivers with higher burden showed less social support and low subjective well-being.

    <p>[Purpose] The purpose of this study was to examine whether experience of falls affects the relationship between subjective assessment of walking and objective motor assessment. [Participants and Methods] Sixty-three community-dwelling elderly aged over 65 years old were the participants. They were divided into a fall group (n=13) and a no-fall group (n=50). The Japanese version of the modified Gait Efficacy Scale (mGES), center of gravity sway, and the Timed up and go test (TUG) were evaluated. [Results] There was no association between mGES and the center of gravity sway, irrespective of fall experience. mGES and TUG showed a significant correlation in the no-fall group, but no significant association in the fall group. [Conclusion] The relationship between subjective and objective assessments of walking differed depending on the experience of falls.</p>

    目的 食と運動の介護予防プログラムTAKE10!を用いて、郵便を利用した通信型の介入を行い、集客型の介護予防教室で認められたような食習慣の変化が認められるかどうかを検証し、集客型の教室が開催できない地域や時期における本プログラムの活用について考察する。方法 北海道の積雪寒冷過疎地域3町村に在住の70歳以上の高齢者143人(平均年齢77.6±5.0歳、男性45人、女性98人)を郵便による通信型介入を5ヵ月間行う介入群(72人)と行わない対照群(71人)に無作為に割付け、このうち、介入前後の調査会に出席し、質問紙を提出した介入群48人、対照群37人を解析対象者とし、介入前後の質問紙による調査(10の食品群の摂取頻度、Dietary Variety Score(DVS)、Food Frequency Score(FFS))から食習慣を比較した。また、介入群を調理従事群と非従事群に分け、両群のDVS、FFSの変化を解析した。結果 介入群は介入前と比較して介入後に、9食品群の摂取頻度、DVS、FFSが有意に増加したが、対照群には有意な変化が認められず、2群間における交互作用が認められた。また、調理従事群、非従事群の両群においてDVS、FFSは介入前後で有意に増加した。結論 TAKE10!プログラムは、通信型の介入が受け入れ可能な対象者において、集客型と同様な食習慣の変化ならびに、同一世帯内での共有を期待できると考えられ、集客型の教室が開催できない地域や時期においての活用は有効であると思われる。(著者抄録)

    <p>【はじめに・目的】</p><p>2013年の国民生活基礎調査(厚生労働省)による要介護原因をみると,転倒・骨折は12.2%を占め,特に女性では15.4%と認知症に次いで第2位となっている.転倒・骨折には骨粗鬆症やサルコペニアが大きく関与することが推察され,特に骨粗鬆症を有する高齢女性では転倒による骨折リスクが大きい.2005年における我が国の骨粗鬆症患者数は1280万人とされており,サルコペニア有病率は7.5%~8.2%と推測され,これらの有病率は高齢者の増加に伴い今後も増えていくことが予想される.骨粗鬆症とサルコペニア対策は,我が国において喫緊の課題となっており,骨粗鬆症とサルコペニアの関連性を調べた研究はみられるものの,骨粗鬆症と握力,歩行速度,筋量をそれぞれ検討した研究は限られている.</p><p> そこで今回,地域在住高齢女性における骨粗鬆症と握力,歩行速度,筋量との関係を明らかにすることを目的とした.</p><p>【方法】</p><p>垂水研究2017に参加した地域在住高齢者380名のうち,主要データに欠損の無い高齢女性266名を分析対象とした.研究デザインは横断研究であり,調査項目として年齢,骨粗鬆症の有無などの基本情報を聴取し,握力,歩行速度,四肢骨格筋量(生体電気インピーダンス法)を測定した.握力は18㎏,歩行速度は1.0m/s,補正四肢骨格筋量(ASMI,四肢骨格筋量㎏/身長m<sup>2</sup>)は5.7kg/m<sup>2</sup>を基準とし,それぞれの値を下回った場合を握力低下,歩行速度低下,筋量低下と定義した.これらの低下の有無と骨粗鬆症の有無の割合をχ<sup>2</sup>検定で比較した.また,握力低下,歩行速度低下,筋量低下のそれぞれを従属変数とし,独立変数を骨粗鬆症の有無,共変量に年齢を投入したロジスティック回帰分析を行った.</p><p>【結果】</p><p>骨粗鬆症の有病率は27.3%で,握力低下は28.6%,歩行速度低下は4.9%,筋量低下は50.0%が該当し,骨粗鬆症のある者では有意に筋量低下に該当する者の割合が高かった(p=0.013).ロジスティック回帰分析においても,筋量低下は骨粗鬆症と有意に関連しており(OR 2.0,95%CI 1.2-3.5,p=0.014),年齢で調整したモデルにおいても筋量低下と骨粗鬆症との関連性は有意であった(OR 1.9,95%CI 1.1-3.4,p=0.028).</p><p>【結論】</p><p>骨粗鬆症を有する地域在住高齢女性において,筋力や歩行速度の低下は認められないものの,筋量が低下している可能性が示唆された.筋量の低下は,将来的に筋力や運動機能の低下を招き,転倒・骨折へと繋がっていく可能性が高い.骨粗鬆症を有する高齢女性においては,筋力や運動機能の評価だけではなく筋量を測定することにより,将来の運動機能低下や転倒・骨折予防のための介入の必要性を把握することが可能と思われる.今回は,問診のみで骨粗鬆症の有無を分類したため,骨粗鬆症の診断を受けていない対象者のなかにも骨密度が低下している者が含まれる可能性がある.今後は骨密度を測定し身体機能や筋量との関係性を検証する必要がある.</p><p>【倫理的配慮,説明と同意】</p><p>本研究は鹿児島大学大学院医歯学総合研究科疫学研究等倫理委員会の承認を受けて行った.ヘルシンキ宣言に基づき,参加者に文書と口頭にて説明し同意を得た.</p>

The multicomponent exercise program had a log-term continuity due to high feasibility. The program was widely used in a clinical setting, particularly preventive project, and easily accepted because an exercise program could be conducted without a specific environment. Further investigations were required to develop the evident strategy for preventing dementia.</p>

    フレイルは,高齢期において生理的予備能が低下することでストレスに対する脆弱性が亢進して不健康を引き起こしやすい状態と定義され,身体的な問題のみならず,精神・心理的問題,さらには社会的問題を含む概念とされる。しかし,これらの多側面でのフレイル判定方法が十分に確立している状況には至っていない。身体的フレイルに関しては,国際的に概ね共通した理解が図られており,わが国での大規模コホート研究によるデータも蓄積されてきており,地域高齢者における身体的フレイルの有症率は7.4%程度とされている。身体的フレイルと判定されると,悪化の一途をたどるわけではなく,適切な介入によって身体機能やADL能力の向上,さらにはフレイルからの脱却が期待されている。認知的フレイルや社会的フレイルに対しても,効果的な介入手段の検討が必要であり,個別を対象とした介入に留まらず,フレイル予防のための地域での人的・物的資源の拡充を含めた地域社会の環境体制の充実も課題のひとつであろう。<br>

    身体活動の不足は、認知症の発症や認知機能の低下に強く関連するため、身体活動を向上させて活動的なライフスタイルを確立することは、認知機能の低下を抑制するために重要な要因である。定期的な運動習慣を有する高齢者では、将来の認知症発症のリスクが軽減され、運動介入による認知機能低下の抑制に対する効果が期待される。特に、有酸素運動を中心とした身体活動の向上は、認知症の発症の予防や遅延に効果が期待されている。認知機能の維持・改善に対するより効果的な運動療法においては、運動による身体活動の促進のみではなく、知的な刺激が伴う活動を付加することが推奨される。高齢期における認知機能の低下を抑制するためには、一時的な運動療法にとどまらず、習慣化できるようにいかに支援するかも重要なポイントとなる。(著者抄録)

    <文献概要>サルコペニアは,高齢期にみられる骨格筋量の減少と筋力もしくは身体機能(歩行速度など)の低下により定義される。サルコペニアは,2016年に国際疾病分類(ICD-10)においてM62.84のコードを取得しており,サルコペニアの治療やリハビリテーション,予防の重要性がさらに高まると考えられる。サルコペニアの定義や分類が整理されつつあるが,サルコペニアの判定方法については臨床的な活用可能性も考慮され,改訂がなされている。現状においては,サルコペニアの予防・改善のためには運動と栄養改善による介入戦略が有効であろうと考えられる。特に,運動療法に関しては,筋力トレーニングを中心とした多面的な運動プログラムが推奨される。しかし,サルコペニアに対する運動介入のエビデンスは十分なレベルではないため,さらにエビデンスが蓄積されていくことが望まれる。

    高齢期における骨格筋の喪失は,全身の虚弱化(フレイル)を加速させ,転倒発生や日常生活活動能力の低下を招くリスクを増大させる.サルコペニア・フレイルについては,これまでに様々な評価方法が提唱されており,その理解と適切な活用が求められる.サルコペニアやフレイルは,しかるべき介入により予防や改善が可能であることが期待されており,身体機能や日常生活活動能力の向上を図ることは,サルコペニアやフレイルから脱却することにもつながる.これらのサルコペニア・フレイルの対策では運動介入が重要な役割を担う.一方で,社会とのつながりが失われ,他者や社会との交流が減少することは,身体的および認知・心理・精神的なフレイルの入り口と捉えることもできる.そのため,個別介入のみならず,社会全体でサルコペニア・フレイルの予防・改善の重要性を意識して,健康長寿の基盤を構築する必要がある.(著者抄録)

    This study aimed to assess the effects of a multicomponent exercise program on physical function and muscle mass in older adults with sarcopenia or pre-sarcopenia. Moreover, we aim to standardize the exercise program for easy incorporation in the daily life of community-dwelling older adults as a secondary outcome. A single-blind randomized controlled trial was conducted with individuals (≥60 years) who had sarcopenia or pre-sarcopenia (n = 72). Participants were randomly assigned to the exercise and control groups. The exercise program consisted of 12 weekly 60-minute sessions that included resistance, balance, flexibility, and aerobic training. Outcome measures were physical function and muscle mass. Assessments were conducted before and immediately after the intervention. Among the 72 participants (mean age: 75.0 ± 6.9 years; 70.8% women), 67 (93.1%) completed the trial. Group-by-time interactions on the chair stand (p = 0.02) and timed "up and go" (p = 0.01) tests increased significantly in the exercise group. Although the exercise group showed a tendency to prevent loss of muscle mass, no significant interaction effects were observed for cross-sectional muscle area and muscle volume. The 12-week exercise program improved physical function in the intervention group. Although it is unclear whether the program is effective in increasing muscle mass, a multicomponent exercise program would be an effective treatment for physical function among older adults with sarcopenia.

    抑うつ高齢者の身体活動量、BDNFおよび脳容量の変化に慢性疼痛が与える影響について検討した。高齢者機能健診に参加した65歳以上の地域在住高齢者59名(男性31名、女性28名、平均73.3±6.0歳)を対象とした。慢性疼痛なし群は36名、慢性疼痛あり群は23名であった。慢性疼痛あり群における各アウトカムの変化量同士の相関分析の結果、ΔGDS(老年期うつ病評価尺度)得点とΔMTL(内側側頭部)萎縮領域の割合との間に有意な正の相関関係が、Δ全脳萎縮領域の割合とΔ歩数との間に有意な負の相関関係が、Δ歩数とΔMVPA(中強度以上の身体活動)との間に有意な正の相関関係が認められた。一方、慢性疼痛なし群における各アウトカムの変化量同士の相関分析の結果では、慢性疼痛あり群と同様にΔ歩数とΔMVPAとの間に有意な正の相関関係が認められたものの、その他の有意な相関関係は認められなかった。

    習慣的な身体活動の向上によって認知機能の維持・改善が期待されているが、認知機能の衰えが疑われる高齢者では、単純な運動課題のみによって脳活動の活性化を促すことは容易ではない。認知機能の改善・維持に対して効果的な運動介入を実践するために、認知課題を負荷しながら(二重課題、多重課題)の有酸素運動などによって、より効率的に脳の活性化をはかることが期待できる。その1つの方法として、有酸素運動に脳活性を促す認知課題を同時に負荷するコグニサイズ(cognicise)が勧められる。コグニサイズとは、cognition(=認知)とexercise(=運動)を掛け合わせた造語で、認知機能低下の抑制を目指した運動プログラムである。同時に課せられる運動課題と認知課題のどちらに対しても注意を向けながら課題を遂行することが求められ、認知機能の低下を抑制する運動介入手段の1つとして、その予防効果が期待されている。(著者抄録)

    アルツハイマー病の代表的な危険因子として、生活習慣に関わる要因が報告されており、なかでも身体活動の不足がアルツハイマー病の発症に強く関連することが示されている。近年では運動介入による認知機能の改善および低下抑制の効果が検証されている。身体活動の促進が認知機能の向上をもたらすメカニズムとしては、多種多様な要素が生物学的、行動学的、社会心理学的レベルで複雑に影響しあって得られるものであると考えられる。とくに、軽度認知障害を有する高齢者では、運動による介入のみならず、同時に脳賦活を促進する課題を促すことが功を奏するであろう。しかし、運動介入によって認知症を予防できる、もしくは発症に明らかに遅延できるとした明確な根拠は不十分であり、とくに適切な運動強度や運動種目、運動期間などについてはさらに根拠を積み重ねていく必要があり、これらを明らかにすることに理学療法の視点から認知症予防を展開していく鍵が秘められているであろう。(著者抄録)

    我々の研究グループは,軽度認知障害を有する地域在住高齢者を対象に,複合的運動プログラムが認知機能に及ぼす効果をランダム化比較試験によって検証し,その有効性を明らかにした。プログラムの有効性については,全般的認知機能や記憶に加え,脳萎縮の状態に有効性が認められた。本資料論文では,介入内容の紹介ならびに一般化可能性について着目し検討を行った。検証された複合的運動プログラムは,長期間の継続性も確認されており高齢者が実施しやすいものであったと考えられる。主に介護予防プログラムの1つとして実施されていることが多く,国内において広く用いられている。更に,運動の実施については特別な環境を必要としないため,新たに取り入れやすいプログラムであると考えられる。今後も,さまざまな場面において継続して取り組めるプログラムを目指し,継続した検討が必要である。(著者抄録)

    フレイルは,高齢期において生理的予備能が低下することでストレスに対する脆弱性が亢進して不健康を引き起こしやすい状態と定義され,身体的な問題のみならず,精神・心理的問題,さらには社会的問題を含む概念とされる。しかし,これらの多側面でのフレイル判定方法が十分に確立している状況には至っていない。身体的フレイルに関しては,国際的に概ね共通した理解が図られており,わが国での大規模コホート研究によるデータも蓄積されてきており,地域高齢者における身体的フレイルの有症率は7.4%程度とされている。身体的フレイルと判定されると,悪化の一途をたどるわけではなく,適切な介入によって身体機能やADL能力の向上,さらにはフレイルからの脱却が期待されている。認知的フレイルや社会的フレイルに対しても,効果的な介入手段の検討が必要であり,個別を対象とした介入に留まらず,フレイル予防のための地域での人的・物的資源の拡充を含めた地域社会の環境体制の充実も課題のひとつであろう。(著者抄録)
