Association between mild cognitive impairment and falls among Chinese older adults: the mediating roles of balance capacity and depressive symptoms.

Background: This study aimed to examine the association between mild cognitive impairment (MCI) and the follow-up risk of falls among Chinese older adults, exploring the mediating roles of balance capacity and depressive symptoms in the association between MCI and falls.

Methods: A total of 5482 adults aged 60 years and above from waves 2015 and 2018 of the China Health and Retirement Longitudinal Study were included for analysis. Cognition was assessed by a global cognition score, which included three tests: episodic memory, figure drawing and Telephone Interview of Cognitive Status.

Understanding the effect of retirement on health behaviors in China: Causality, heterogeneity and time-varying effect.

Retirement is an important turning point during the course of life, but few studies have examined the effects of retirement on a broad range of health behaviors in China. We use the longitudinal data of the China Health and Nutrition Survey (CHNS) from 2004 to 2015 to conduct empirical analysis. Fuzzy discontinuity regression was used to assess the association between retirement and health behaviors in the entire sample and subgroups based on gender and education.
