Depression is a significant public health issue affecting relationships, work, and overall quality of life. In Japan, the number of patients with mood disorders, including depression, has increased significantly in recent years. Although malnutrition is known to worsen mental health and elevate the risk of depression and anxiety, the role of specific nutrients in preventing and managing depression remains unclear. This study investigated the association between nutrient intake, particularly vitamin K, and depressive symptoms, accounting for frailty in the Japanese population. Among the 607 participants in this study, 122 (20.1%) experienced depressive symptoms. Vitamin K was independently associated with depressive symptoms using a forward stepwise selection method. The relationship between vitamin K tertiles and depressive symptoms was assessed through multivariate logistic regression analysis. Adjusted for covariates (age, sex, frailty, education level, living status, exercise habits, energy intake, and alcohol consumption), the odds ratios (ORs) for depressive symptoms were significantly lower in tertile 3 compared to tertile 1. The ORs (95% confidence interval, p-value) for tertile 2 and tertile 3 were 0.64 (0.38–1.07, 0.087) and 0.48 (0.28–0.82, 0.008), respectively. Lower vitamin K intake was independently associated with depressive symptoms. Further research is necessary to confirm the role of vitamin K in preventing depressive symptoms.

Exploring the characteristics of smartphone proficiency among community-dwelling older adults: A population-based cross-sectional study . Educational Gerontology 2026年

記述言語：日本語出版者・発行元：Educational Gerontology

Smartphones are essential for older adults’ independence and social engagement. However, limited research has systematically examined the specific characteristics and factors associated with levels of smartphone proficiency among older adults. This population-based cross-sectional study assessed smartphone proficiency in 324 community-dwelling older adults (median age: 73 years, 59.9% female) in Japan using the short version of the mobile device proficiency questionnaire. Hierarchical clustering (Ward’s method) identified four proficiency levels: low (24%), basic operations-focused (41%), limited advanced function use (28%), and high (6%). Higher proficiency was associated with greater education, cognitive function, and diverse app usage, while lower proficiency correlated with limited app use and higher frailty risk. Differences in proficiency reflected sociodemographic, cognitive, and functional factors. Tailored education and support are crucial to addressing the digital divide and enhancing quality of life. Future research should investigate the longitudinal effects of smartphone proficiency on cognitive and functional well-being.

Objectives: To examine whether satisfaction with meaningful activities (MA) is associated with self-rated sleep quality and sleep duration among community-dwelling older adults. Methods: Data were drawn from 833 individuals aged ≥65 years who participated in a health survey between 2018 and 2019 in Japan. Sleep quality (good, moderate, or poor) and duration (< 6, 6–8, or ≥8 h) were assessed through a questionnaire. Participants selected the MA they considered most meaningful from a list of 95 activities in the Aid for Decision-Making in Occupation Choice, and their satisfaction with these MA were measured. Results: Ordinal logistic regression analysis, with sleep quality or duration as the dependent variable and satisfaction with MA as the independent variable, showed that higher satisfaction with MA was significantly associated with lower odds of poor sleep quality (OR: 0.84, 95% CI: 0.72–0.97, p =.03), but not with sleep duration. However, the association was not significant in sensitivity analyses that reversed the model. Conclusions: Satisfaction with MA may be associated with better sleep quality in older adults. Clinical Implications: Evaluating and enhancing satisfaction with MA may help identify older adults at risk of poor sleep quality, indicating that MA may be useful in supporting sleep.

Background: Psychological frailty (PsF), encompassing cognitive and emotional vulnerabilities, remains understudied despite its potential impact on health outcomes in older adults. This cross-sectional study aimed to explore the characteristics of diverse aspects of PsF, including cognitive frailty (CF), lower cognitive function, and affective frailty (AF), and to examine their associations with health-related outcomes in community-dwelling older adults. Methods: Data were analysed from 420 community-dwelling older adults participating in the Tarumizu Study in Japan, excluding those exhibiting physical or social frailty. Participants were categorised into Robust, Lower cognitive function, CF, AF, and Multi-domain PsF groups. AF was assessed using five items from the Geriatric Depression Scale, focusing on emotional vulnerability. Health outcomes included self-rated health, subjective memory complaints (SMC), and functional ability of daily living. Associations were analysed using adjusted multiple regression models controlling for covariates. Results: PsF was present in 39.5% of the cohort (lower cognitive function: 18.1%, CF: 7.6%, AF: 11.0%, Multi-domain PsF: 2.9%). In the adjusted models, only AF showed a significant positive association with SMC (adjusted risk ratio = 1.62, 95% CI: 1.06–2.42, p = 0.023). No significant associations were found between any PsF domain and subjective health or daily functional ability in the adjusted models. Conclusions: AF, characterised by emotional vulnerability, was uniquely associated with SMC, suggesting emotional factors may play a more central role than cognitive decline in shaping perceptions of memory problems. These findings highlight the heterogeneous nature of PsF and underscore the need for nuanced assessments to inform targeted prevention and intervention strategies.

Background: While previous studies have shown inconsistent associations between volunteer participation and cognitive health in later life, less attention has been paid to qualitative aspects of engagement. This study examined whether psychological engagement in volunteer activities is associated with subjective cognitive function in community-dwelling older adults. Method: This cross-sectional study included 431 community-dwelling older adults (mean age: 78.2 ± 5.7 years; 90.0% female) from self-management exercise class. Volunteer activity status was assessed using a self-reported participation questionnaire. Psychological engagement (Volunteer Engagement; VE) was evaluated using a three-item version of the Utrecht Work Engagement Scale adapted for volunteer settings. Based on VE scores, the participants were categorized into three groups: non-volunteers, low-engagement volunteers, and high-engagement volunteers. Subjective cognitive function was assessed using three self-reported items addressing memory complaints and disorientation, derived from the Kihon Checklist. Logistic regression analyses were conducted to examine the associations between (1) volunteer activity status and (2) VE scores with low cognitive function, adjusting for relevant covariates. Results: Of 431 participants, 60.1% reported volunteering. There was no significant association between being a volunteer and low cognitive function. In contrast, high-engagement volunteers had significantly lower odds of low cognitive function than non-volunteers (OR = 0.51, 95% CI: 0.27–0.97). No significant differences were observed between low-engagement volunteers and non-volunteers. Conclusions: These findings suggest that psychological engagement in volunteer activities rather than mere participation may be more closely related to the subjective cognitive health of older adults. Highlighting this engagement may help inform policies and programs for promoting cognitive health.

Objectives: This two-wave longitudinal study examined whether changes in satisfaction with meaningful activities (MA) were associated with subsequent subjective memory complaints (SMC) among community-dwelling older adults between 2019 and 2021. Method: Health surveys were conducted among local people at two time points: baseline (2019, before the COVID-19 pandemic) and follow-up (2021, during the pandemic). The participants were 275 community-dwelling older adults aged ≥65 years without cognitive decline at baseline. Satisfaction with MA was assessed using the Aid for Decision-Making in Occupation Choice and categorized as maintained/improved or decreased at follow-up. SMC was measured using four items developed by Tsutsumimoto and quantified according to the total number of complaints. Results: Older adults who maintained or improved satisfaction with MA showed no significant increase in SMC (p = 0.30), whereas those who demonstrated decreased satisfaction experienced a significant increase in SMC (p = 0.02). In the generalized linear mixed-effects model adjusted for covariates, a significant association was observed between decreased satisfaction with MA and increased SMC scores (β = 0.32, 95% CI = 0.09–0.55, p < 0.01). Conclusion: Maintaining and improving satisfaction with MA may be associated with a reduced risk of SMC increase in older adults.

This cross-sectional observational study aimed to clarify the relationship between satisfaction with grave visitation and depressive symptoms among Japanese older adults. We analysed older adults who participated in a community health survey (n = 1025). Participants selected meaningful activities from the 95-item Aid for Decision-Making in Occupation Choice and rated their satisfaction on a five-point scale. Depression symptoms were assessed using the 15-item Geriatric Depression Scale. Grave visitation ranked fourth among all activities and was the most frequently chosen social activity. Higher satisfaction with grave visitation was associated with a significantly lower prevalence of depression, particularly in the hopelessness dimension. After adjusting for potential covariates in a Poisson regression analysis, satisfaction with grave visitation was significantly related to depression symptoms (prevalence ratio,.58; 95% confidence interval,.35–.96). Discussing beliefs about the deceased and ancestors and helping to increase satisfaction with grave visitation may help alleviate depressive symptoms.

Combinations of intrinsic capacity and frailty and their associations with self-rated health in community-dwelling older adults . Aging Clinical and Experimental Research37 ( 1 ) 275 2025年9月

記述言語：日本語掲載種別：研究論文（学術雑誌）出版者・発行元：Aging Clinical and Experimental Research

Background: Intrinsic capacity (IC) and frailty are distinct but complementary frameworks for understanding the heterogeneity of aging. Although both have been linked to self-rated health, little is known about how their combined status relates to older adults’ health perceptions. This cross-sectional study investigated how combinations of IC and frailty status were associated with self-rated health among community-dwelling older adults. Method: Data from 593 participants (mean age: 73.9 years, female: 62.2%) in the 2019 Tarumizu Study were analyzed. IC was evaluated across five key screening domains (cognition, vitality, sensory, locomotion, and psychological) using a 10-point scale, with scores ≥ 9 classified as high IC. Frailty was assessed using the Japanese version of the Cardiovascular Health Study criteria and dichotomized into robustness and frailty (pre-frailty or frailty). Self-rated health was assessed with a four-point item and dichotomized into good or poor. Participants were classified into four groups: robust with high IC, frailty with high IC, robust with low IC, and frailty with low-IC. Results: Group proportions were: 30.0% (robust with high IC), 23.1% (frailty with high IC), 15.9% (robust with low IC), and 31.0% (frailty with low IC). Multivariable logistic regression showed that only the frailty with low-IC group had significantly greater odds of poor self-rated health compared to the robust with high-IC group (OR = 3.55, 95% CI: 1.34–9.36). Conclusions: Co-occurrence of low IC and frailty was significantly associated with poor self-rated health. These findings suggest that considering IC and frailty may enhance understanding of self-rated health in later life.
