Revista chilena de neuro-psiquiatría
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
... that fulfilled the DSM-IV diagnostic criteria for eating disorders and to 54 normal female students. 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.
