The L-shaped association between body roundness index and all-cause mortality in osteoporotic patients: a cohort study based on NHANES data.

ABSTRACT:

Purpose

This study aims to investigate the relationship between the body roundness index (BRI) and overall mortality rates in individuals with osteoporosis (OP), utilizing information sourced from the NHANES database, in order to assess BRI's capability as an indicator for predicting mortality risk.

Methods

Data from NHANES (2005 to 2010, 2013-2014, and 2017-2018) were analyzed, including 1,596 osteoporotic individuals aged 50 and above. BRI was calculated based on waist circumference (WC) and height, categorizing participants into high (>4.07) and low (≤4.07) BRI groups. To analyze the relationship between BRI and mortality while accounting for important covariates, we employed weighted Cox proportional hazards models, conducted Kaplan-Meier survival analyses, and utilized
