Objective To examine the relationship between body roundness index (BRI) and depression risk in individuals with hyperlipidemia. Methods Data were obtained from the National Health and Nutrition Examination Survey (NHANES) 2005—2018, including 20 492 adults with hyperlipidemia. Multivariable logistic regression and restricted cubic spline analyses were used to analyze the association between BRI and depressive status. Results Multivariable analysis revealed a significant U-shaped relationship between BRI and depression risk (P=0.002), with an inflection point at 3.15. For BRI<3.15, each unit increase in BRI was associated with a 33% decrease in depression risk (OR=0.67, 95% CI: 0.50-0.88, P=0.004 3). For BRI≥3.15, each unit increase in BRI was associated with a 7% increase in depression risk (OR=1.07, 95% CI: 1.04-1.09, P<0.000 1). In tertile analysis, the highest BRI tertile showed a 30% increased risk of depression compared to the lowest tertile(OR=1.30, 95% CI: 1.13-1.49, P=0.000 2). Conclusion There is a U-shaped relationship between BRI and depression risk in individuals with hyperlipidemia, suggesting that both excessively low and high BRI values may increase the risk of depression.Large prospective cohort studies are needed to validate these findings.
