There is substantial evidence about comorbidity between eating disorders, depression and social anxiety. Aim: To compare the presence of social anxiety and depression and its prevalence in eating disordered patients and normal subjects. Subjects and Methods: A structured clinical interview, the Eating Attitudes Test , the Eating Disorder Inventory (EDI), the Liebowitz Social Anxiety Scale (LSAS) and the Hamilton Depression Rating Scale (HDRS) were administered to 54 patients that fulfilled the

Results: Patients with eating disorders ranked significantly higher on the EAT-40 and on the EDI and its factors, including comorbidity scales (p < 0.001). Prevalence of social anxiety was significantly higher in eating disordered patients (40. 7% versus 3.7%) (p < 0.001), particularly among anorexics (66.6%) (p < 0,001) and 14.8% of the eating disordered patients ranked within the severe range (p < 0.001). The risk for moderate to very severe social anxiety was 5.5 times higher among them. Prevalence of depressive symptoms was significantly higher in eating disordered patients (18.5% versus 0%) (p < 0.001), specially among anorexics (66.6%) (p < 0,001) and 18.5% of the eating disordered patients ranked within the severe or very severe range (p < 0.001). The risk for moderate to very severe depression was 23.7 times higher among them. Conclusions: Depressive and/or social anxiety disorders and their prevalence rates are confirmed according to the evidence in eating disordered patients, mainly among patients suffering from anorexia nervosa.
