Prevalence of eating disorders and psychiatric comorbidity in a clinical sample of type 2 diabetes mellitus patients.
BACKGROUND
A few studies have shown high rates of eating disorders and psychiatric morbidity in patients with type 2 diabetes mellitus.


OBJECTIVE
Disturbed eating behavior and psychiatric comorbidity in a sample of T2DM patients.


METHODS
Seventy type 2 diabetes mellitus patients between 40 and 65 years of age (mean, 52.9 +/- 6.8) from a diabetes outpatient clinic were sequentially evaluated. The Structured Clinical Interview for DSM-IV, Binge Eating Scale and Beck Depression Inventory were used to assess eating disorders and other psychiatric comorbidity. In addition to the descriptive analysis of the data, we compared groups divided based on the presence of obesity (evaluated by the body mass index) or an eating disorder.


RESULTS
Twenty percent of the sample displayed an eating disorder. Binge eating disorder was the predominant eating disorder diagnosis (10%). Overall, the group of obese patients with type 2 diabetes mellitus presented rates of psychiatric comorbidity comparable to those seen in their nonobese counterparts. However, the presence of an eating disorder was associated with a significant increase in the frequency of anxiety disorders (57.1% x 28.6%; p = 0.044).


CONCLUSIONS
In our study sample, the occurrence of eating disorders was increased compared to rates observed in the general population, with the predominance of binge eating disorder. The presence of an eating disorder in type 2 diabetes mellitus patients was associated with higher rates of anxiety disorders.
