Joint associations of handgrip strength and functional disability with cognitive impairment in older adults.

ABSTRACT:

Background

Handgrip strength (HGS) and functional disability may reflect interconnected biological processes contributing to functional decline. However, the extent to which their co-occurrence predicts cognitive impairment in aging populations remains unclear. This study investigated the joint association of low HGS and functional disability with cognitive impairment in a nationally representative cohort of older Chinese adults.

Methods

We analyzed data from the China Health and Retirement Longitudinal Study (2011-2020), including participants aged ≥ 60 years. Based on baseline HGS and functional disability status, participants were categorized into four groups. Logistic regression and Cox proportional hazards models were used to examine cross-sectional and longitudinal ass
