Abstract
Purpose
Studies have shown a high prevalence of food addiction (FA) in bariatric surgery candidates. This study examines prevalence of FA prior to and one year after bariatric surgery and the determinants of preoperative FA. Additionally, this study investigates how preoperative variables affect excess weight loss (EWL) one year after bariatric surgery.
Materials and Methods
This prospective observational study included 102 patients at an obesity surgery clinic. Self-report measures, including demographic characteristics, the Yale Food Addiction Scale 2.0 (YFAS 2.0), the Depression Anxiety Stress Scale (DASS-21), and the Dutch Eating Behavior Questionnaire (DEBQ) were used two weeks before and one year after surgery.
Results
The FA prevalence among bariatric surgery candidates decreased from 43.6% before surgery to 9.7% one year after surgery. Among independent variables, female gender and anxiety symptoms were associated with FA (OR = 4.20, 95% CI: 1.35–24.16, p = 0.028 and OR = 5.29, 95% CI: 1.49–18.81, p = 0.010, respectively). Only gender had a significant association with %EWL after surgery (p = 0.022); females had a higher mean %EWL than males.
Conclusion
FA is common among candidates for bariatric surgery, especially in women and participants with anxiety symptoms. The prevalence of FA, emotional eating, and external eating decreased after bariatric surgery.
