Association of sarcopenia and frailty with sleep quality trajectories in middle-aged and older Chinese adults: findings from a nationally representative cohort study.

ABSTRACT:

Background

Few studies have examined the associations of sarcopenia, frailty, and sleep quality (SQ) trajectories among middle-aged and older Chinese adults. Our aim was to investigate these relationships using a nationally representative longitudinal study.

Methods

The study utilized 2011-2015 data from the China Health and Retirement Longitudinal Study (CHARLS), focusing on individuals aged 45 years and above. Sarcopenia and frailty were assessed at baseline. SQ was evaluated biennially via interview-based assessments from 2011 to 2015, with SQ scores calculated accordingly. A group-based trajectory model was applied to analyze the aging trajectory of SQ over time, while multinomial logistic regression was used to examine the associations between sarcopenia and frailty wit
