The Relationship Between BMI, Body Composition, and Fat Mass Distribution in Rou-en-Y Gastric Bypass Patients

Background Type 2 diabetes mellitus (T2DM) with central obesity is a common clinical presentation in Chinese patients. Body mass index (BMI) is a criterion determining central obesity that, when combined with dual-energy X-ray absorptiometry (DXA), accurately reflects body composition and fat mass d...

Description
Summary:Background Type 2 diabetes mellitus (T2DM) with central obesity is a common clinical presentation in Chinese patients. Body mass index (BMI) is a criterion determining central obesity that, when combined with dual-energy X-ray absorptiometry (DXA), accurately reflects body composition and fat mass distribution. The utility of DXA-derived measures in the evaluation of metabolic surgery still needs to be investigated. Methods In this cohort study, 78 Chinese patients with central obesity (WC ≥ 90 cm for males, WC ≥ 85 cm for females) or BMI above 27.5 kg/m 2 underwent gastric bypass between October 2010 and October 2012. The patients were followed for 12 months. Preoperative, perioperative, and postoperative metabolic parameters and DXA results were prospectively collected and analyzed. Results A total of 57 of 78 cases (73.1%) were diagnosed with central obesity. There was a significant decrease in BMI, WC, and WHR at each point in time ( P
