AB  - BACKGROUND: In 2015, intrinsic capacity (IC) was proposed by the WHO as a new 
      measure for healthy aging. Evidence has shown that physical activity (PA) 
      benefits the physical and mental health of older adults. However, the association 
      between PA and IC among older adults was not well evaluated or reported. This 
      study aims to investigate the association between PA and general and specific IC 
      among Chinese older adults. METHOD: The study included individuals aged 60 and 
      above from the China Health and Retirement Longitudinal Study in 2015. The IC 
      scores were constructed based on the WHO concept of five domains: psychological 
      capacity, cognition, locomotion, vitality, and sensory abilities. Total PA and 
      leisure PA were measured based on different activity purposes. Linear 
      mixed-effects models and generalized linear mixed-effects models were developed 
      to assess the associations between PA and IC. RESULTS: A total of 3359 
      participants were included in this study. Older adults who reported some PA were 
      associated with a higher composite IC score, with a mean difference of 0.14 (95% 
      CI: 0.09-0.18, p < 0.001) compared to those who reported no PA. In terms of 
      leisure PA, physically active adults had a higher composite IC score with a mean 
      difference of 0.06 (95% CI: 0.03-0.09, p < 0.001). Older adults with a high level 
      of leisure PA also had a significantly higher composite IC score (diff. in mean = 
      0.07, 95% CI: 0.01-0.13, p < 0.05) compared to those with low-level leisure PA. 
      In addition, PA was positively and significantly associated with three specific 
      IC domains: locomotion, cognition, and vitality. CONCLUSIONS: Improving both 
      general and leisure PA can be an effective way to prevent the decline in IC among 
      older adults, thus reducing the personal and public load of primary healthcare 
      for aging countries such as China.
