Introduction: The body fat index (BMI) is an anthropometric measure that evaluates the percentage of total fat. In Colombia, this index has shown high predictive capacity for the diagnosis of metabolic syndrome; however, its diagnostic utility as an indicator of excess weight has not been studied. Objective: To evaluate the diagnostic capacity of the body adiposity index as an indicator of excess weight in young Colombian adults. Methods: A cross-sectional descriptive study of 5,436 university students (59.4% female). The CAR was estimated using the Bergman et al. ([hip circumference in cm]/[height in m2]1,5-18). Overweight and overweight and obesity' classification were determined using the body mass index. As diagnostic utility indicators of the IAC, the area under the curve (AUC), sensitivity, specificity, positive likelihood ratio (RV+), negative likelihood ratio (RV-) were calculated through a Receiver Operating Curve (ROC) analysis. Results: The mean age of those assessed was 20.5 years (95% CI 20.4-20.6) and the mean TSI was 25.2% (95% CI 26.1-26.3). The cut-off point of the CAR that allowed for the proper classification of overweight subjects was 26.5% (J-youden 35.5% 95% CI 32.7-38.3), with a sensitivity of 76,5% (IC95% 74.1%- 78.9%), specificity 59.0% (IC95% 57.5%- 60.5%), RV+ 1.87 (IC95% 01.78-1.96) RV- 0.57 (IC95% 0.48-0.66) and ABC 0.763 (IC95% 0.747-0.779; p<0,001). Conclusion: In young Colombian adults, the CAI allowed for a proper classification of excess weight when compared to the BMI. Studies in other population groups are recommended that may complement the results found in this study.
