Engaging in leisure activities is essential for mental health in older adults. This longitudinal study (n = 1,101, mean age = 69.20 ± 6.23 years at baseline) examined the associations between leisure participation and mental health over 6 years in three waves: 2016, 2018, and 2020. Pearson's correlation analyses and generalized estimating equations were performed for data analyses. The frequency of participation in physical and social activities was significantly positively associated with happiness, life satisfaction, and self-rated health, and significantly negatively associated with depression. Passive activities were significantly positively associated with happiness, life satisfaction, and self-rated health but not with depression. The time effect had no significant association with any mental health outcomes. These findings highlight the importance of leisure activities in promoting mental health among older adults. Policy makers should encourage older adults to engage in physical and social leisure activities.
