Decreased binge eating behaviour, weight and comorbid depressive symptoms in obese binge eaters during a Multidisciplinary Cognitive Behavioural Weight Loss Therapy

Abstract

BED is seen as a disorder that is scarcely diagnosed and treated but comes with a diversity of mental and somatic health problems. This study examined changes in binge eating behaviour, weight and comorbid depressive symptoms during a one-year multidisciplinary Cognitive Behavioural Weight Loss Therapy (M-CBWT). It was expected that mood disorder would moderated changes in weight and binging when compared between patients with and without mood disorder. 167 clinically severe obese patients with either BED or OSFED, between the age of 18 and 71, were included in this study. Repeated measures analyses of variance showed that binge eating behaviour, weight and depressive symptoms decreased during the M-CBWT treatment. Moderation analyses did not show an interaction between mood disorder and changes in binge eating and weight. The decrease in binge eating, weight and depression are potentially attributable to M-CBWT due to emotion-regulation topics used in the treatment. The presence of a mood disorder does not seem to influence these changes.
