    Yuka Suzuki, Kaori Honjo et al.•ARTICLE•Journal of Epidemiology and…•2025•References: 23

We examined (1) the association between the number of social roles and self-rated health (SRH) and (2) the mediation effects of ikigai (the sense of life worth living) and the size of close social networks to the association. Methods We analysed the cross-sectional baseline questionnaire data of the Japan Public Health Center-based Prospective Study …

Our study underlines the clinical importance of social isolation after a large-scale natural disaster and draws attention to the need for appropriate prevention measures
