Double Jeopardy Versus Double Benefit: The Role of Age and Leisure Activities in the Incidence of Disability Among Chinese Older Adults.

Objectives: This paper analyzes the double jeopardy effect of age and double benefit of leisure activities in the incidence of disability. Methods: This study uses data from the Chinese Longitudinal Healthy Longevity Survey between 2002 and 2014. Disability status is measured by activities of daily living. Leisure activities include physical and social activities. A generalized linear mixed model with a time-lag design is used to analyze the trajectory of being disabled. Results: Older ages are associated with double jeopardy of disability: higher initial probability and faster pace. The double benefit of leisure activities is confirmed: lower initial probability and a slower pace of change in disability over time. The age pattern is substantially alleviated when leisure activities and other covariates are present. Discussion: Although the risk of disability rises with advancing age, the over-time trajectory can be flattened by engagement in leisure activities and other factors. [ABSTRACT FROM AUTHOR]
