Associations between sleep duration trajectories and physical dysfunction among middle-aged and older Chinese adults.

ABSTRACT:

Background

The relationship between a single time-point measurement of sleep duration and physical dysfunction has been extensively investigated. However, few researches has concentrated on the effects of sleep duration trajectories. This study sought to evaluate the association between sleep duration trajectories and physical dysfunction in a longitudinal cohort of middle-aged and older Chinese individuals.

Methods

This research included a large pool of subjects (n = 7157) between the ages of 45 and 80 from the China Longitudinal Study of Health and Retirement (CHARLS). Utilizing sleep duration data collected periodically between 2011 and 2015, the sleep duration trajectory was plotted using the group-based trajectory modeling (GBTM). Physical dysfunction was evaluated usin
