Association Between Sleep Duration and Cognitive Frailty in Older Chinese Adults: Prospective Cohort Study.

ABSTRACT:

Background

Disturbed sleep patterns are common among older adults and may contribute to cognitive and physical declines. However, evidence for the relationship between sleep duration and cognitive frailty, a concept combining physical frailty and cognitive impairment in older adults, is lacking.

Objective

This study aimed to examine the associations of sleep duration and its changes with cognitive frailty.

Methods

We analyzed data from the 2008-2018 waves of the Chinese Longitudinal Healthy Longevity Survey. Cognitive frailty was rendered based on the modified Fried frailty phenotype and Mini-Mental State Examination. Sleep duration was categorized as short (<6 h), moderate (6-9 h), and long (>9 h). We examined the association of sleep duration with cognitive frailty
