BACKGROUND: Older adults who engage in group sports and exercises achieve greater health benefits than those who exercise by themselves. The benefits of group participation may vary depending on the type of sports/exercise they engage in. The present study aimed to identify the association between specific sports and exercise types performed in groups and evaluate the longitudinal changes in multidimensional frailty scores among community-dwelling older adults in Japan. METHODS: We used 3-year follow-up data from the Japan Gerontological Evaluation Study and analyzed 33,746 men and 36,799 women aged ≥ 65 years. To elucidate the relationship between participation in 20 types of group sports/exercises in 2016 (baseline) and the change in frailty score (using the Kihon Checklist, KCL) from 2016 to 2019, we performed linear regression analyses through multivariate adjustments for age group, self-rated health, marital status, living alone, occupational status, years of education, alcohol drinking status, smoking status, equivalent income, and disease status using an inverse probability weighting method. P < 0.05 was considered statistically significant. RESULTS: The mean change in KCL scores over 3 years was + 0.62 and + 0.61 points in men and women, respectively, implying the degree of frailty worsened. The sports/exercise types that significantly prevented increments in KCL scores for both sexes compared to non-participants were hiking (men: B, - 0.36; women: B, - 0.29), walking (men: B, - 0.26; women: B, - 0.24), tennis (men: B, - 0.23; women: B, - 0.24), ground golf (men: B, - 0.21; women: B, - 0.19), and weight exercises (men: B, - 0.19; women: B, - 0.16). CONCLUSION: Participation in specific sports and exercise groups offer significant physical and psychological benefits for frailty prevention among older adults in Japan. The results of this study may offer substantive evidence to encourage older adults to participate in group activities for the prevention of multidimensional frailty. It will also help public health stakeholders to decide which type of sports and exercise groups to promote in a community.

Abstract Background and Objectives Evidence remains inadequate regarding the benefits of participation in community gathering places, which is Japan’s primary strategy for preventing functional disability in older adults, in other domains of health and well-being. This longitudinal study examined the associations of participation in community gathering places with an array of subsequent health and well-being outcomes among older adults. Research Design and Methods We used three-wave data (2013, 2016, and 2019) from Japan Gerontological Evaluation Study (n = 5,879 or 4,232 depending on the outcome). Our exposure was participation in community gathering places in 2016. We assessed 34 health/well-being outcomes in 2019 across six domains. We adjusted for pre-baseline covariates including prior outcome values in 2013. Results Compared with nonparticipation, participation in community gathering places was associated with some outcomes in the following three domains: physical/cognitive health (better higher-level functional capacity), social well-being (more frequent participation in hobby groups, senior citizens clubs, learning or cultural groups, and seeing more friends within a month), and pro-social/altruistic behaviors (more frequent participation in volunteering) (After Bonferroni correction as p &amp;lt; 0.0015, 0.05/34). Discussion and Implications Evidence was mixed and more modest for the outcomes in three other domains, mental health, psychological well-being, and health behaviors. Promoting participation in community gathering places may not only fulfill its original goal (i.e., preventing functional disability) but also enhance other domains of human well-being, potentially by increasing social interactions.

<title>Abstract</title>This study aimed to identify factors associated with engaging in sports and exercise volunteering among older adults. We used cross-sectional data from the Japan Gerontological Evaluation Study (JAGES), a nationwide mail survey of 20,877 older adults from 60 municipalities. Multilevel mixed-effects logistic regression analysis was used to investigate the correlation between engaging in sports and exercise volunteering and 39 variables classified into five factors: (1) demographic and biological, (2) behavioral, (3) psychological, cognitive, and emotional, (4) social and cultural, and (5) environmental factors. Among the analyzed samples, 1580 (7.6%) participants volunteered a few times/year or more often. Factors that showed positive association with the volunteering were older age, a current drinking habit, excellent self-rated health, high proportion of sports group participants in a living area, low municipal population density, and rich social and cultural features (i.e., social cohesion, support, network, and participation). Meanwhile, those that had a negative association were women, low level of education, deteriorated instrumental activities of daily living, having a past or current smoking habit, poor self-rated health, and depressive symptoms. We clarified the characteristics of the population that is more likely to participate in sports and exercise volunteering as well as those of the population that is less likely to participate and requires support.

PURPOSE: This study aimed to identify the association between a specific sports type and exercise group participation and longitudinal changes in sociopsychological health among community-dwelling older adults. METHODS: Three years of data from the Japan Gerontological Evaluation Study were used, comprising a total of 33,746 men and 36,799 women aged ≥65 years. To determine the relationship between 20 types of sports and exercise group participation in 2016 (baseline) and changes in depressive symptoms (Geriatric Depression Scale: GDS-15), self-rated health (4-point scale), subjective well-being (11-point scale), and frequency of laughter (day/month) from 2016 to 2019, we performed linear regression analyses with conducting a multivariate adjustment for potential confounders using an inverse probability weighting method. RESULTS: The mean changes over three years were + 0.32 and + 0.28 in GDS-15, -0.06 and - 0.05 in self-rated health, -0.08 and - 0.06 in subjective well-being, and - 1.21 and - 1.19 in frequency of laughter, in men and women, respectively. Men playing golf in a group were more likely to suppress an increase in the GDS-15 (B = -0.11, 95% CI -0.18--0.05) and decreases in self-rated health (0.04, 0.02-0.06), subjective well-being (0.07, 0.02-0.12), and frequency of laughter (0.45, 0.11-0.80). Women participating in walking, weight exercises, and hiking groups were more likely to prevent an increase in the GDS-15 (-0.12, -0.19--0.04; -0.09, -0.18--0.01; and - 0.16, -0.30--0.03, respectively) and decreases in self-rated health (0.03, 0.01-0.05; 0.03, 0.01-0.06; and 0.08, 0.04-0.12, respectively). CONCLUSIONS: Golf in older men and walking, weight exercises, and hiking in older women could be recommended as an effective program for promoting sociopsychological health among older adults in Japan.
