ABSTRACT: Background
The relationship between body roundness index (BRI) and low muscle mass (LMM) remains unclear. This study investigated their association in American adults under 60 years.Methods
This secondary analysis utilized de-identified data from the National Health and Nutrition Examination Survey (NHANES, 2011-2018; n = 8,065 adults <60 years). Multivariable logistic regression evaluated associations between BRI and LMM, while multivariable linear regression assessed relationships between BRI and appendicular skeletal muscle mass (ASM)/BMI. Restricted cubic splines (RCS) tested nonlinearity, and receiver operating characteristic (ROC) curves compared BRI's predictive performance against other body measurements indices. Finally, to assess the robustness of results, we cond
