Background: Psychopathology has been associated with poorer outcomes after bariatric surgery. Impulsivity has been shown to be associated with obesity through links to pathological eating behavior such as binge eating. Recent literature suggests that impulsivity is linked to poorer outcomes post-bariatric surgery. The aim of this systematic review is to synthesize the current evidence on the impact of impulsivity on post-bariatric surgery weight loss.
Methods: A literature review was performed in August 2018. Original studies investigating the relationship between impulsivity and weight loss post-bariatric surgery were evaluated.
Results: Six studies with a total of 911 patients were analyzed. There were two case-control, two prospective observational and two retrospective observational studies. The post-operative follow-up ranged from 0.5 to 12 years. The most common measure of trait impulsivity was the Barratt Impulsivity Score (BIS), which was used in five studies. Only one study demonstrated a direct association between BIS scores and post-operative weight loss. Two studies reported an indirect effect of impulsivity on weight loss, mediated via pathological eating behavior. Scores specific to state impulsivity showed a significant impact on post-surgical weight loss.
Conclusion: Impulsivity may adversely affect post-operative outcomes after bariatric surgery. However, this may be specific to state impulsivity rather than trait impulsivity. Patients with a higher state impulsivity may benefit from closer follow-up post-bariatric surgery.
