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). the history of admission to psychiatry clinics and the ratio of suicide attempt were more frequent in obese group. the ratio sixty one of the 146 (41,2%) subjects with obesity had diagnosed as depressive disorder according to DSM-IV criteria. Thirty three of 71 BED (46,5%) had diagnosed as depressive disorder. there are no significant differences between BED(+) and BED(-) groups for depression (p > 0.05). Cognitive impulsivity and nonplanning activity scores of depressive group were significantly higher than the subjects without depression. (p < 0.05). Cognitive impulsivity scores of depressive obese were significantly higher than the obese without depression (p < 0.05).

| BED(+) | BED(-) | Control | p | |
|---|---|---|---|---|
| Mean±SD | Mean±SD | Mean±SD | ||
| BMI (kg/m2) | 33.3 ± 4.1 | 33.4 ± 5.7 | 22.2 ± 2.1* | ><0.001 |
| EAT score | 27.6 ± 12.3 | 25.5 ± 12.7 | 7.2 ± 7.8* | ><0.001 |
| BDI score | 16.2 ± 9.3 | 14.4 ± 10.5 | 6.9 ± 75.2* | ><0.001 |
| BIS-Total | 67.5 ± 10.8** | 59.9 ± 17.9 | 60.0 ± 16.9 | >0.003 |
| BIS-NPA | 26.6 ± 4.1*** | 25.3 ± 5.1 | 24.1 ± 5.1 | >0.002 |
| BIS-CI | 20.6 ± 7.0 | 23.2 ± 16.4 | 22.2 ± 12.7 | >0.475 |
| BIS-MI | 21.8 ± 3.7 | 21.6 ± 4.0 | 20.9 ± 4.2 | >0.260 |
Conclusion:
Obesity is strongly related with depression and impulsivity. 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.
