There is inconsistent evidence on the association between community-level social capital and the health or well-being of older adults. This study examined the association between community-level social capital and multidimensional health and well-being outcomes using an outcome-wide approach. We used data from the Japan Gerontological Evaluation Study, a nationwide cohort study of Japanese older adults (analytic samples: 47,227 for outcomes obtained from the long-term care insurance registry and 34,183 for other outcomes). We assessed three aspects of school-district-level community social capital in 2016 (civic participation, social cohesion, and reciprocity) and 41 subsequent health and well-being outcomes through 2019. We performed either a modified multilevel Poisson regression or a multilevel logistic regression analysis. We adjusted for pre-baseline characteristics, prior outcome values, and individual-level social capital from the 2013 wave. Even after Bonferroni correction, we found that community-level social capital was associated with some subsequent social well-being and physical/cognitive health. For example, community-level reciprocity was associated with a higher prevalence of taking a social role (Prevalence ratio [PR] = 1.03, 95% confidence interval [CI] = 1.02, 1.04) and undergoing health screening (PR = 1.03, 95% CI: 1.01, 1.04). There was modest evidence that community-level civic participation was associated with a higher competency of intellectual activity (PR = 1.01, 95% CI: 1.01, 1.02) and community-level social cohesion was associated with a reduced onset of functional disability (PR = 0.94, 95% CI: 0.90, 0.98). Community-level social capital may promote social well-being and some physical/cognitive health outcomes.
