The relationship between body roundness index (BRI), a new obesity index, and frailty has not been established. This study aims to compare the associations of traditional mass (BMI) BRI with risk all-cause mortality. clinical data 15,157 participants over 40 years old from National Health Nutrition Examination Survey (NHANES) 2003 2018 were analyzed. Based on weighted logistic regression, COX regression restricted cubic spline, BMI odds mortality estimated. receiver operating characteristic curve (ROC) concordance used evaluate ability predict survival. Weighted showed that trend increasing increase (P for < 0.0001, respectively). After adjusting all confounding factors, association was stronger (OR: 1.20, 95% CI: 1.13–1.27, P 0.0001), slightly weaker 1.14, 1.08–1.21, 0.0001). ROC area under (AUC) predicting 0.628, while AUC 0.603, difference two significant (PDeLong 0.001). In addition, in survival analysis, U-shaped Piecewise based inflection point shows when 7.33, an reduces (HR: 0.85, 0.78–0.92, ≥ increases 1.19, 1.03–1.38, = 0.02); 33.57, 0.84, 0.78–0.91, 1.18, 1.04–1.34, 0.01).
