Objective: There are few studies of successful aging in China. This study was designed to investigate the distribution, and related factors, of successful aging in an elderly Chinese population.
Methods: A cross-sectional, community-dwelling elderly population was surveyed in Shanghai, China. We defined successful aging based on a multi-dimensional model. Correlates of successful aging were explored through the Shanghai Successful Aging Project Questionnaire, which includes sociodemographic questions, and a battery of standardized instruments, including the Chinese version of the Mini-mental State Examination, activities of daily living, and the Life Satisfaction Index A (LSIA).
Results: The rate of successful aging was 46.2% [95% confidence interval (CI) 43.6–48.7] among people aged 65 or above, and the rate for males was higher than that for females. The rate was much lower for those aged 85 years or over (9.4%). Logistic regression analysis suggested that female gender and older age were unfavorable factors for successful aging. A higher score on the LSIA, more leisure activities and being currently married related to successful aging.
Conclusion: The rate of successful aging in Shanghai, China is similar to that found in studies from western countries. There are some potentially modifiable factors that may relate to successful aging.
