[Prediction of Weight Regain After Bariatric Surgery by Night Eating, Emotional Eating, Eating Concerns, Depression and Demographic Characteristics].

Abstract

OBJECTIVE We aimed to determine whether night eating, emotional eating, eating concerns, depression, and some demographic characteristics are associated with the weight regain observed after bariatric surgery.  METHOD: The study group consisted of 117 adults with an age range of 21 to 56 years, residing at different cities of Turkey. The participants were assessed at the post-operative 12th- 98th months with Night Eating Questionnaire, Dutch Eating Behavior Questionnaire-Emotional Eating Subscale, Eating Disorder Examination Questionnaire, Eating Concern Subscale of Eating Disorder Scale and Beck Depression Inventory. Mann Whitney U Test, Pearson Correlation Analysis and Hierarchical Multiple Linear Regression were used for data analyses.  RESULTS: Post-operatively, 13.7% of participants regained weight. The results displayed that depression, night eating, emotional eating and eating concern scores were higher in the participants who regained weight. Being married, emotional eating and time elapsed after the surgery positively, while knowledge on the amount of daily nutrients needed negatively predicted weight regain.  CONCLUSION: Some demographic and psychological factors may affect the weight regain observed after bariatric surgeries. This study is the first in this field in Turkey, and longitudinal studies are needed. A long term multidisciplinary follow-up protocol is recommended for successful treatment of obesity.
