Correlation between Body Mass Index and Homa Index in Bariatric Patients
Abstract
Abstract Background and aims: Overweight and obese individuals are prone to an insulin resistance status assessed in the present study by the HOMA index ( Homeostasis model assessment ). This prospective study assessed the body mass index (BMI) and the insulin resistance status (HOMA index) in obese patients after bariatric surgery (gastric sleeve, gastric by-pass). Material and Methods: The study included 48 patients who were assessed before the bariatric surgery and at 6 months thereafter. The assessment included the body mass index (BMI) and the HOMA index before meal. Results: There was a significant positive correlation between BMI and HOMA index, mostly between weight loss and improvement in insulin resistance status (rho = 0.308, p = 0.0335). Conclusions: BMI decreases significantly after bariatric surgery, which correlates positively with an improvement in insulin resistance status.
