Association between sleep characteristics and physical functioning in middle-aged and elderly adults: findings from Chinese cohorts.

ABSTRACT:

Aims

Aging is associated with declines in muscle strength and physical function, and sleep plays a crucial role in maintaining musculoskeletal health. This cohort study, based on the China Health and Retirement Longitudinal Study (CHARLS), aims to explore the relationship between sleep characteristics and physical performance in middle-aged and elderly individuals.

Methods

A total of 2,998 participants from the CHARLS cohort were included, with baseline data from the 2011 survey and follow-up data from the 2015 survey. Nighttime sleep and napping patterns were assessed, and changes in sleep duration over time were categorized. Physical functioning was assessed through handgrip strength, the chair stand test, the walking test, appendicular skeletal muscle mass, and SPPB score
