Association between urbanization levels and frailty among middle-aged and older adults in China: evidence from the CHARLS.

ABSTRACT:

Background

Rapid urbanization is underway in China. However, the impact of urbanization on frailty remains unclear. This study aims to investigate the relationship between urbanization and frailty among middle-aged and older adults.

Methods

We analyzed nationally representative data from the China Health and Retirement Longitudinal Study (CHARLS) spanning 2011 to 2018. After applying inclusion and exclusion criteria, 10,758 non-frail individuals at baseline were analyzed. The exposure of interest was the comprehensive urbanization level. Urbanization level (0.072-0.689) was assessed using the entropy method. Frailty was assessed using the frailty index (FI), which ranges from 0 to 100. Frailty was defined as FI ≥ 25, and the urbanization-frailty association was assessed usin
