MMS-CB: Preoperative Dry Lean Body Mass as a Prognostic Factor for Excess Weight Loss After Bariatric Surgery.
Study Details
Study Description
Brief Summary
Bariatric surgery is currently the only method that has proven long-term effectiveness in obesity. Although the benefit of physical activity on weight loss has been demonstrated, no correlation has ever been reported between preoperative lean body mass and postoperative weight loss. Dry lean mass is probably an essential prognostic factor for the effectiveness of bariatric surgery.
The main objective of this study is to define a preoperative dry lean body mass threshold as a worst prognostic factor for weight loss one year after bariatric surgery.
The management of patients included in this study was modelled on the management usually offered to patients followed for the same pathology in the diabeto-endocrinology department. There are no study-specific examinations that are not part of current practice.

Outcome Measures
Primary Outcome Measures
- Measurement of dry lean mass in pre-operative by impedance measurement [12 months after bariatric surgery]
Excess weight loss at M12: ideal weight is defined in relation to height for a BMI of 25.0 kg/m2. Excess weight is the difference between the observed weight and the ideal weight. Excess weight loss is the ratio of weight loss to excess weight.
