Body roundness index and mortality risk in chronic diseases: a national prospective longitudinal study in China.

ABSTRACT:

Background

The body roundness index (BRI) has emerged as a refined anthropometric indicator that integrates waist circumference and height to quantify body shape characteristics and metabolic risk. However, its longitudinal associations with mortality across diverse chronic diseases remain underexplored. This study aims to investigate these associations and their potential mechanisms.

Methods

This longitudinal study utilized data from the China Health and Retirement Longitudinal Study (CHARLS), covering a 9-year follow-up from baseline (2011-2012) to 2020. The study cohort comprised 11,750 middle-aged and older Chinese adults. BRI was calculated using waist circumference and height. The primary outcome was all-cause mortality. Cox proportional hazards models were used to ass
