Percentage of maximum weight lost as an optimal parameter of weight regain after bariatric surgery in Chinese patients with diabetes
Authors' conclusion
Among Chinese patients with obesity and T2DM who underwent bariatric surgery, WR quantified as %MWL predicted 3-year postoperative glucose metabolism deterioration better than the alternatives; 20% MWL was the optimal cutoff point.
Study context
- Population
- Chinese patients with obesity and T2D who underwent bariatric surgery, followed up to 3 years
- Participants
- 249 patients
- Exposure
- Measures of weight regain: %MWL vs weight change, BMI change, % of presurgery weight, % of nadir weight
- Outcome
- Discrimination (C-index) of weight regain (WR) measures for glucose metabolism deterioration (new antidiabetic medication or insulin use, or HbA1c rise ≥0.5% to ≥5.7%)
- Follow-up
- Up to 3 years
Main finding
As reported in the abstract
C-index for glucose metabolism deterioration · within 3 years
