The Chinese Longitudinal Healthy Longevity Study (CLHLS), which provided the data analyzed in this article, is jointly supported by the National Natural Sciences Foundation of China (81573207, 71233001, 71490732, and 81573247) and the U.S. National Institute of Aging (2P01AG031719 and 3P01AG031719-07S1). This work also supported by the National Key R&D Program of China (2018YFC2000400) and the Construction of High-Level University in Guangdong (C1050008 and C1051007) and the University Revitalization Program in Eastern, Western and Northern Guangdong (G619080438).

N2 - Background: Evidence of the trend of the incidence of activities of daily living (ADL) disability among Chinese older people is limited. We aimed to investigate the time trends and potential risk factors for the incidence of ADL disability among Chinese older people (≥65 years). Methods: We established two consecutive and nonoverlapping cohorts (6,857 participants in the 2002 cohort and 5,589 participants in the 2008 cohort) from the Chinese Longitudinal Healthy Longevity Survey. ADL disability was defined as the need for assistance with at least one essential activity (dressing, bathing, toileting, eating, indoor activities, and continence). Cox proportional hazards models were used to identify factors associated with the trend in the incidence of ADL disability from 2002 to 2014. Results: The incidence (per 1,000 person-years) of ADL disability decreased significantly from 64.2 in the 2002 cohort to 46.6 in the 2008 cohort (p < .001), and decreasing trends in the incidence of ADL disability were observed for all sex, age, and residence subgroups (all p < .001), even after adjusting for multiple potential confounding factors. Moreover, we found that adjustment for sociodemographic, lifestyle information, and cardiovascular risk factors (hypertension, diabetes, heart disease, and stroke) explained less of the decline in ADL disability during the period from 2002 to 2014. Conclusion: The incidence of ADL disability among the older adults in China appears to have decreased during the study period, and this finding cannot be explained by existing sociodemographic and lifestyle information and cardiovascular risk factors.
