Older people who engage in sports and exercise in a group render greater benefits for sociopsychological aspects compared to exercising alone. The aim of this study was to identify the prevalence of specific types of sports and exercise groups and the association with self-rated health, depressive symptoms, and frequency of laughter among community-dwelling older people. We used cross-sectional data from the 2016 Japan Gerontological Evaluation Study and analysed 63,465 males and 68,497 females aged ≥65 years. The top three most popular types among males were golf (11.3%), walking (8.4%), and ground golf (6.3%). Among females, the top three were fitness exercises (13.8%), walking (8.3%), and weight exercises (6.2%). After adjusting for potential confounders, engaging in golf with a group was significantly related with excellent self-rated health (prevalence ratio, PR, 1.31 in male and 1.78 in female), low depressive symptoms (PR, 0.70 and 0.71), and a high frequency of laughter (PR, 1.12 and 1.13). Among females, walking displayed a significant relationship with all three characteristics (PR, 1.23, 0.79, and 1.06, respectively). Golf in older males and walking in older females might be the first choice for an effective programme to spread sports and exercise groups within the older Japanese community.

Background Frailty is the highest risk factor for incident disability and mortality. Social participation is a modifiable factor for reducing adverse outcomes among independent older adults. However, the association between social participation and incident disability and mortality among frail older adults remains unclear. Therefore, we examined the association between various social activities and incident disability and mortality. Methods This nationwide prospective cohort study (The Japan Gerontological Evaluation Study) recruited older adults with frailty, aged 65 years and older (N = 9090) who were followed up for 6 years (2010–2016). We examined incident disability and all‐cause mortality at the end of the follow‐up period. Frailty was assessed using the Kihon Checklist. The independent variable was social participation in 2010, grouped into the following seven categories: hobby groups, sports groups or clubs, volunteer groups, senior citizens' clubs, industries, neighborhood communities, and paid work. Results The incidence of disability among participants was 19.5% (1770) and that of mortality was 19.2% (1753). Belonging to sports groups or clubs (Hazard Ratios [HR] = 0.74; 95% Confidence Interval [CI] = 0.57, 0.98) or hobby groups (HR = 0.77; 95% CI = 0.60, 0.98) was significantly associated with a lower risk of incident disability. Meanwhile, hobby groups (HR = 0.68; 95% CI = 0.56, 0.83), sports groups or clubs (HR = 0.71; 95% CI = 0.57, 0.88), volunteer groups (HR = 0.69; 95% CI = 0.54, 0.88), and senior citizens' club (HR = 0.75; 95% CI = 0.61, 0.90) were associated with lower risk of incident mortality. Conclusions Social participation was associated with a lower risk of incident disability and mortality, not only in healthy older adults but also in frail older adults who are at higher risk of incident disability and mortality. This suggests that frail older adults should be encouraged to participate in all the seven types of social participation examined in this study, as this may lower the risk of subsequent disability and mortality.

BackgroundLittle is known about the prospective association between community-level social capital and individual-level frailty onset. Therefore, this study aimed to examine the impact of community-level social capital on frailty onset among older adults using 3-year longitudinal data.MethodsThis prospective cohort study recruited non-institutionalised older adults from the Japan Gerontological Evaluation Study, established in 2013 and robust older adults were followed up for 3 years. We assessed three aspects of community-level social capital (civic participation, social cohesion and reciprocity), and employed a multilevel logistic regression analysis; frailty was evaluated using the Kihon Checklist questionnaire, which has been widely used as a screening tool for frailty in Japan.ResultsIn total, 21 940 older adults (from 384 communities) who were robust at baseline (2013) completed the follow-up survey (2016). Participants’ mean age (SD) was 71.8 (4.9) years, and 51.2% were female. In the follow-up period, frailty onset occurred in 622 participants (2.8%). Regarding community-level social capital variables, civic participation was inversely associated with frailty onset (OR=0.94, 95% CI 0.90 to 0.97, p=0.001), after adjusting for individual-level and community-level covariates. The potential intermediate factors of individual social relationships and health behaviours did not largely change the results. This association was found regardless of individual socioeconomic status.ConclusionsLiving in a community with rich civic participation, such as engagement in social activities, was associated with lower frailty onset among older adults. Community development that fosters social participation is essential for frailty prevention.
