The association between body roundness index and mortality in diabetes

Abstract

BACKGROUND: The association between body roundness index (BRI) and all-cause mortality and the occurrence of cardiovascular disease (CVD) in patients with diabetes is unknown. This study aimed to determine the association between BRI and all-cause/CVD mortality in a diabetic cohort. METHODS: A total of 8227 individuals with diabetes from the 1999-2018 National Health and Nutrition Examination Survey (NHANES) database were included. Multifactorial Cox regression models were used to analyze the association between BRI and mortality in patients with diabetes. Multivariate-adjusted restricted cubic spline (RCS) regression was used to test for nonlinearity. RESULTS: During a median follow-up of 7.25 years, a total of 27.22% died, with 9.18% of these deaths due to CVD. After fully adjusting for potential confounders, BRI remained significantly associated with all-cause/CVD mortality in the diabetic population. The restricted cubic splines revealed no significant nonlinear relationship between BRI and all-cause mortality (P = 0.29) or CVD mortality (P = 0.73). BRI was better associated with all-cause/CVD mortality in patients with diabetes compared to other body metabolic indices. CONCLUSIONS: In patients with diabetes, we found an association between BRI and all-cause/CVD mortality.
