Prediction of weight regain after bariatric surgery in terms of night eating, emotional eating, eating concern, depression and psychosocial demographics

The purpose of this study was to determine the prediction of weight regain after bariatric surgery in terms of depression, night eating, emotional eating, eating concern and various psychosocial demographics. The population of the study group consists of post-op adults (n=117), ranging from age 21 to 56 ((x ̅=36.99, Ss=7.85) with post-op 12 to 98 months (¯X=28.53, Ss=12.93) living at different cities all around Turkey. Night Eating Questionnaire (NEQ), Dutch Eating Behavior Questionnaire (DEBQ) (emotional eating subscale), Eating Disorder Examination Questionnaire (EDE) (eating concern subscale), Beck Depression Inventory (BDI) and demographic information form developed by the researcher are used in this study. For the analysis, Mann Whitney U Test, Pearson Correlation Analysis and Hierarchical Multiple Lineer Regression are used. The findings are: 13.7% of the patients experienced postsurgery weight regain; results of depression (𝑋̅=22.88, p<.01), night eating (𝑋̅=1.81, p<.01), emotional eating (𝑋̅=2.89, p<.01) and eating concern (𝑋̅=3.83, p<.01) are higher at weight regain group; being married, postsurgery duration and presence of emotional eating contribute to the weight regain; and finally knowledge of necessary daily food intake decreases the weight regain. Results of this research were discussed within the framework of the up to date literature and suggestions were made.
