Introduction: The aim of this study was to reveal the relationship between ABSI (A Body Shape Index), BRI (Body Roundness Index), HOMA (Homeostatic model assessment) index and lipid parameters in overweight and obese patients.
Materials and methods: Two hundred eighty eight patients, who were followed up in the obesity outpatient clinic through- out year 2017 and met inclusion/exclusion criteria, were enrolled in the study. Anthropometric measurements were done accord- ing to international standards. The weight was measured using a body composition analyzer. Height was measured using a wall- mounted stadiometer. BMI (body mass index), ABSI, BRI, and HOMA index values were calculated by the standard international formulas. Fasting plasma glucose, insulin, and lipid levels were measured in blood samples taken after an average 10±2 hours of fasting. The data were further assessed by multivariate regression analysis and ROC curve analysis.
Results: Of the participants, 77 (26.7%) were female and 211 (73.3%) were male. BRI and triglyceride values were inde- pendent determinants of HOMA index value. In the ROC analyzes in which predictive values of BRI and ABSI for overweight (BMI ≥25) and obesity (BMI≥30) were assessed, it was determined that BRI had better predictive values, but ABSI had insufficient predictive values. The area under the ROC curve for BRI in overweight patients was 0.929 and it was 0.949 in obesity. The BRI cut-off value (4.421888) predicts overweight patients with a sensitivity of 81.9% and a specificity of 92.1% while it (5.160223) predicts obesity with a sensitivity of 92.4% and a specificity of 86.1%.
Conclusions: This study demonstrated that BRI and triglyceride values are independent determinants of HOMA index and that BRI is predictive for overweight and obesity, whereas ABSI has insufficient predictive values.
