Differences in the Association Between Working Status and Self-Rated Health According to Financial Satisfaction Among Older Adults Aged ≥75 Years: A Cohort Study of Silver Human Resources Centers in Japan

This prospective cohort study examined the differences in the association between working status and self-rated health (SRH) in older adults aged ≥75 years when stratified according to financial satisfaction. The study participants answered questionnaires in 2022 and 2024. The exposures were working status factors (e.g., number of working days/week), and the outcome was SRH decline over two years. Modified Poisson regression models were used to analyze these associations in all participants and according to financial satisfaction (high/low). Among all participants (n = 2230), older adults with no working days (adjusted relative risk: 0.73; 95% confidence interval = [0.53, 1.00]) or worked a high number of days (0.80; [0.65, 0.98]) had a lower risk of SRH decline than those who worked a medium number of days. These results were replicated only in the high financial satisfaction group. Policymakers should consider these differences when formulating strategies to provide job opportunities for older adults.
