Disgust, impulsivity and depressive dimensions in subjects at risk for bulimia nervosa and/or binge eating disorder.

PURPOSE: the study aims to assess the depressive symptoms, the disgust feeling and the impulsivity index in subjects showing a high risk of binge eating disorder (BED) and/or bulimia nervosa (BN) through a cross-sectional study of 150 participants. RESULTS: There was no significant difference regarding age, sex, employment and marital status between subjects at high risk for BED/BN (Group A) and controls (Group B). However, participants in group A presented higher scores of depressions (p = 0.021), impulsivity (p = 0.027) and Disgust (p = 0.030) with significant associations. CONCLUSION: The neurobiological basis for these associations might be related to a dysfunction in the insular cortex.
