The relationship between leisure activity participation and cognitive function among older Chinese adults: the differences across gender and age.

As population aging increased globally, this study aimed to examine the relationship between leisure activity participation and cognitive function in the older Chinese population and the gender and age differences in this relationship. A total of 12526 individuals aged 60 years and older from the 2018 Chinese Longitudinal Healthy Longevity Survey were obtained for this study. Multiple linear regression analysis was used to explore the relationship. This study found productive, physical, intellectual, recreational and social activities were associated with cognitive function. Males enjoyed extra benefits from recreational activities compared with females. Females enjoyed extra benefits from productive activities and social activities compared with males. Older age enjoyed extra benefits from productive activities, physical activities, intellectual activities, recreational activities, social activities in comparison with younger age. Thus, Chinese older adults need to make efforts to increase the time and variety of leisure activities, especially for the oldest old. Compared with other types of leisure activities, it's more important for old men to participate in recreational activities, and for old women to participate in productive activities and social activities.
