The longitudinal trajectory of post-surgical % total weight loss among middle-aged women who had undergone bariatric surgery.

ABSTRACT: Middle-aged women are at a higher risk of being obese. We examined the trajectory of post-surgical % total weight loss (%TWL) among middle-aged female bariatric patients. We fitted sequential generalized estimating equations models to analyze a sample of women who received bariatric surgery in 1995-2012, aged 40-65 years at the time of surgery (N = 158,292) whose pre-operative body mass index (BMI) was ≥ 30 kg/m² in the Bariatric Outcomes Longitudinal Database. The %TWL computed by 100% × (pre-surgery BMI - post-surgery BMI) / pre-surgery BMI showed different trajectories depending on type of surgery. For gastric banding, %TWL increased rapidly right after bariatric surgery and started to decrease around 1 year after surgery. For Roux-en-Y gastric bypass (RYGB) and sleeve gastre
