Loss of control over eating predicts outcomes in bariatric surgery patients: a prospective, 24-month follow-up study.
OBJECTIVE This study examined the clinical significance of  loss of control ( LOC ) over eating in bariatric surgery patients over 24 months of prospect i ve , multiwave follow-ups . METHOD Three hundred sixty-one gastric bypass surgery patients completed a battery of assessment s before surgery and at 6 , 12 , and 24 months following surgery . In addition to weight loss and LOC over eating , the assessment s targeted eating disorder psychopathology , depression levels , and quality of life . The study was conducted between January 2002 and February 2008 . RESULTS Prior to surgery , 61 % of patients reported general LOC ; postsurgery , 31 % reported LOC at 6-month follow-up , 36 % reported LOC at 12-month follow-up , and 39 % reported LOC at 24-month follow-up . Preoperative LOC did not predict postoperative outcomes . In contrast , mixed models analyses revealed that postsurgery LOC was predictive of weight loss outcomes : patients with LOC postsurgery lost significantly less weight at 12-month ( 34.6 % vs 37.2 % BMI loss ) and 24-month ( 35.8 % vs 39.1 % BMI loss ) postsurgery follow-ups . Postsurgery LOC also significantly predicted eating disorder psychopathology , depression , and quality of life at 12- and 24-month postsurgery follow-ups . CONCLUSIONS Preoperative LOC does not appear to be a negative prognostic indicator for postsurgical outcomes . Postoperative LOC , however , significantly predicts poorer postsurgical weight loss and psychosocial outcomes at 12 and 24 months following surgery . Since LOC following bariatric surgery significantly predicts attenuated postsurgical improvements , it may signal a need for clinical attention
