OBESITY, RECURRENCE
Obesity is a significant global health concern.Weight regain is a major challenge facing bariatric teams. A systematic review identified 5 categories of risk factors associated with weight regain: temporal, anatomical, genetic, dietary, and psychiatric factors.Given that weight regain has been associated with recurrence of medical comorbidities and deterioration in quality of life,This multisite RCT sought to determine the efficacy of a telephone-based cognitive behavioral therapy (tele-CBT) intervention delivered 1 year after bariatric surgery in improving weight loss, disordered eating (ie, binge eating and emotional eating), and psychological distress (ie, depressive and anxiety symptoms) at 1.5 years after surgery compared with a treatment-as-usual control group (ie, standard postoperative bariatric care). Our study reports initial outcomes (ie, first follow-up period at 1.5 years after surgery) of an RCT with a follow-up period extending to 3 years after surgery. Primary hypotheses were that the tele-CBT group would report greater weight loss and greater improvements in psychosocial functioning (ie, binge eating, emotional eating, depression, and anxiety) compared with the control group.
