ABSTRACT
OBJECTIVES: To compare the severity of binge eating (BE), food addiction (FA), and body image dissatisfaction between candidates to bariatric and long-term post-bariatric patients; and investigate the association between dysfunctional eating behaviors and body mass index (BMI) and body image dissatisfaction after metabolic bariatric surgery.
METHODS: 86 patients seeking metabolic bariatric surgery and 59 patients who underwent Roux-en-Y Bypass Gastric at least two years ago (a mean of 7 years ago) were included. The mental disorders have been investigated through the Diagnostic and Statistical Manual for Mental Disorders – version 5 (DSM-5) criteria. The severity of BE, FA, and body image dissatisfaction were assessed through the Binge Eating Scale (BES), the modified Yale Food Addiction Scale 2.0 (mYFAS 2.0), and the Body Shape Questionnaire (BSQ), respectively.
RESULTS: There was no statistically significant difference in the scores of the mYFAS 2.0 (p = 0.929), BES (p = 0.336), and BSQ (p = 0.759) between groups. Among the post-bariatric patients, the mYFAS 2.0 and the BES significantly correlated with the BMI (r = 0.301, p = 0.024 and r = 0.291, p = 0.042, respectively). The BSQ scores were not significantly correlated with BMI (r = 0,207, p = 0,149) but were associated with the mYFAS (0.408, p = 0.004) and the BES (r = 0.526, p < 0.001). The scores of BES significantly predicted the scores of body image dissatisfaction in a linear regression model.
CONCLUSION: Patients who underwent metabolic bariatric surgery a long time ago did not have better food- and eating-related behaviors and were not more satisfied with their body image, despite weighing less. Dysfunctional eating behaviors may impair weight outcomes and body image satisfaction.
