A body shape index and sarcopenia risk in middle-aged and older adults: evidence from the China Health and Retirement Longitudinal Study.

ABSTRACT:

Background

The A body shape index (ABSI) has been associated with various diseases, and existing research suggests a link with sarcopenia. However, systematic evaluations focusing on Asian populations-particularly middle-aged and older adults in China-remain insufficient, and the specific association mechanisms and predictive value have yet to be fully elucidated. This study aimed to examine this relationship utilizing data from the China Health and Retirement Longitudinal Study (CHARLS) database.

Methods

A total of 1873 participants aged ≥ 45 years with complete data from the 2015 CHARLS were included. Eligibility criteria required the availability of: (1) parameters necessary for ABSI calculation, namely, waist circumference (WC), height, and weight; (2) sarcopenia assessm
