Association between body roundness index and suicidal ideation in U.S. adults: A cross-sectional study

Year: 2025

Type: article

Abstract: The relationship between the body roundness index (BRI) and suicidal ideation has not been previously examined. This study aimed to investigate this association through a cross-sectional analysis. The data used in this study was extracted from the National Health and Nutrition Examination Survey ranging from 2011 to 2012 to 2017–2018. The BRI was calculated from body measurement data, while a questionnaire was used to assess suicidal ideation. Weighted multivariable logistic regression analysis, weighted stratified analysis, and smooth curve fitting were conducted to assess the relationship between the BRI and suicidal ideation. Results: A total of 12,878 participants were included in the study with 441 of them reported experiencing suicidal thoughts. After adjusted for all covariates, a one-unit increase in BRI was associated with a 5 % greater likelihood of having suicidal thoughts [1.05 (1.00, 1.10)]. Additionally, BRI was categorized into quartiles, and individuals in the highest quartile were 1.52 times as likely to experience suicidal thoughts compared to those in the lowest quartile [1.52 (1.03, 2.25)]. There were no interaction effects between BRI and suicidal ideation for any subgroups stratified by demographics. The present study indicated that a greater BRI was significantly associated with higher levels of suicidal ideation. The findings underscore the importance of considering BRI as a potential indicator for identifying individuals at elevated risk of suicidal ideation. The study also emphasizes the need for a shift towards a weight-inclusive approach in public health, which can help reduce societal pressures and mitigate the psychological impact of weight stigma. • Each unit rise in body roundness linked to 5 % higher odds of suicidal thoughts. • Body roundness index may help identify those at higher risk of suicidal thoughts. • Weight-inclusive approaches promote mental health by reducing societal pressures. • Addressing weight stigma can mitigate psychological distress linked to suicide risk.
