FRIDAY, April 5, 2019 (HealthDay News) -- Several patient behaviors are associated with weight regain after Roux-en-Y gastric bypass (RYGB) surgery, including sedentary time, eating fast food, and eating when feeling full, according to a study published online April 4 in the Annals of Surgery.
Wendy C. King, Ph.D., from the University of Pittsburgh Graduate School of Public Health, and colleagues conducted a prospective cohort study involving adults who underwent RYGB between 2006 and 2009. Assessments were performed before surgery, at six months, and annually for up to seven years. A total of 1,278 individuals with adequate follow-up were included.
Weight was measured a median of eight times during a median of 6.6 years. The researchers observed independent associations between weight gain and sedentary time (2.9 percent for highest versus lowest quartile), eating fast food (0.5 percent per meal/week), eating when feeling full (2.9 percent), eating continuously (1.6 percent), binge eating and loss-of-control eating (8.0 percent for binge eating and 1.6 percent for loss of control versus neither), and weighing oneself less than weekly (4.2 percent). Younger age, venous edema, poorer physical function, and more depressive symptoms were postsurgery characteristics independently associated with greater weight regain.
"Several postsurgery behaviors and characteristics associated with greater weight regain were identified, which inform integrated health care approaches to patient care and identify high-risk patients for intervention efforts to improve long-term weight loss maintenance after RYGB," the authors write.
