Rationale: Anthropometric indicators are essential for assessing body fat and abdominal obesity, as well as predicting health conditions and survival. The Body Roundness Index (BRI), which incorporates waist circumference and height, is a promising tool for evaluating metabolic risks and visceral adipose tissue dysfunction. This study aimed to determine the optimal cutoff points for the BRI as a predictor of metabolic syndrome in the Brazilian population.

Methods: This population-based cross-sectional study used data from the 2013 National Health Survey. To establish the BRI cutoff points, we used the metabolic syndrome risk classification as the gold standard, which considers a high waist circumference along with at least three additional risk components, based on international criteria. A Receiver Operating Characteristic (ROC) curve analysis was performed to assess specificity and sensitivity. All analyses were conducted using R software for Windows.

Results: The prevalence of metabolic syndrome in the Brazilian population was found to be 46.2%. Among individuals with multiple metabolic syndrome components, 25.8% (n=677) of men and 32.0% (n=1,150) of women presented at least three risk factors. The syndrome was more prevalent in women (50.8%) than in men (40.0%). The optimal BRI cutoff points were similar for both sexes. For women, the threshold was 3.757 (AUC: 0.833), with a sensitivity of 90.7% and a specificity of 63.0%. For men, the cutoff point was 3.965 (AUC: 0.906), with a sensitivity of 93.1% and a specificity of 76.4%.

Conclusion: The Body Roundness Index demonstrated strong discriminatory power in predicting metabolic syndrome in the Brazilian population. These findings support its potential use in clinical practice and future research on metabolic risk assessment.
