BACKGROUND: Initial weight loss after bariatric surgery has been associated with improvements in reproductive hormones and sexual functioning in women. Few studies have investigated the durability of these changes. OBJECTIVES: Investigate changes in

The frailty model, an extension of the proportional hazards model, is often used to model clustered survival data. However, some extension of the ordinary frailty model is required when there exist competing risks within a cluster. Under competing ri

Severe obesity (body mass index ≥35 [calculated as weight in kilograms divided by height in meters squared]) is associated with significant medical comorbidity and increased mortality. Bariatric surgery induces weight loss, the extent of which can

Background Limited data guide the prediction of weight loss success or failure after bariatric surgery according to presurgery factors. There is significant variation in weight change after bariatric surgery and much interest in identifying preoperat

Obtaining standardized weights in long-term studies can be difficult. Self-reported weights are more easily obtained, but less accurate than those from a calibrated scale and may be inaccurately reported. Previous studies have reported that women ten
