Background: Maladaptive eating behaviors after bariatric surgery are thought to compromise weight outcomes, but little is known about their frequency over time.Objective: This study investigates the presence of subjective binge eating (SBE), objective binge eating (OBE) and picking and nibbling (P&N) before surgery and at different time periods postoperative, and their association with weight outcomes.Methods: This cross-sectional study assessed a group of patients before surgery (n = 61), and three postoperative groups: 1) 90 patients (27 with laparoscopic adjustable gastric band (LAGB) and 63 with Laparoscopic Roux-en-Y Gastric Bypass (LRYGB)) assessed during their 6 month follow-up medical appointment; 2) 96 patients (34 LAGB and 62 LRYGB) assessed during their one year follow-up medical appointment; and 3) 127 patients (62 LAGB and 55 LRYGB) assessed during their second year follow-up medical appointment. Assessment included the Eating Disorders Examination and a set of self-report measures.Results: In the first ten months after surgery fewer participants reported maladaptive eating behaviors. No OBEs were reported at 6 months. SBE episodes were present in all groups. P&N was the most frequently reported eating behavior. Eating behavior (P&N) was significantly associated with weight regain, and non-behavioral variables were associated with weight loss.Conclusions: This study is cross-sectional study which greatly limits the interpretation of outcomes and no causal association can be made. However, a subgroup of postoperative patients report eating behaviors that are associated with greater weight regain. The early detection of these eating behaviors might be important in the prevention of problematic outcomes after bariatric surgery. (C) 2014 Elsevier Ltd. All rights reserved.
