Abstract

This study aims to investigate the association between Body Roundness Index (BRI) and urinary incontinence (UI) subtypes (stress [SUI], urge [UUI], and mixed [MUI]). This cross-sectional study analyzed NHANES 2001 to 2018 data from 28,639 participants aged ≥20 years. Participants were stratified by BRI quartiles. Multivariable logistic regression examined associations between BRI and UI subtypes. Restricted cubic spline analysis explored nonlinear relationships. Threshold effect analysis identified inflection points. In fully adjusted models, each unit increase in BRI increased risk by 12% for SUI (OR = 1.12, 95% CI: 1.10-1.14) and UUI (OR = 1.12, 95% CI: 1.10-1.13), and 13% for MUI (OR = 1.13, 95% CI: 1.11-1.16) (all P
