P-544 - Role of mood and impulsivity in obese people with binge eating disorder

Abstract

Objective The aim of study was to evaluate mood and impulsivity in obese people with binge eating disorder. Method A total of 149 obese subjects [71 with Binge Eating Disorder (BED) and 78 without BED] were included in the study and compared to 151 non-clinical populations. They were assessed with the Structured Clinical Interview (SCID-I), Eating Attitudes Test (EAT), Beck Depression Inventory (BDI), and Barrat Impulsiveness Scale-11 (BIS-11). Results The ratio of obese subjects with BED is 47,6%. Obesity and BED prevalence was higher in female patients. Childhood obesity was significantly more frequent in obese subjects with BED (p   0.05). Cognitive impulsivity and nonplanning activity scores of depressive group were significantly higher than the subjects without depression. (p  [Table-1].

Impulsivity was significantly higher in depressive obese subjects than non-depressive ones. Futhermore, impulsivity was a prominent feature in obese subjects with BED. This also provides clues for influences of each of these two characteristics on obesity.
