Abstract

The primaty objective is to determine whether the presence anxiety disorders is related to depressive comorbidity in subjects suffering from ED, while taking into account certain variables which may be related to depression [subjects' age, ED duration, prior incidents of anorexia nervosa in BN subjects, inpatient or outpatient status, nutritional state (as measured by Body Mass Index or BMI)]. Our secondary objective is to evaluate the relative chronology of the onset of anxiety disorders and depressive disorders in anorexic and bulimic subjects.

METHOD:

We evaluated the frequency of depressive disorders in 271 subjects presenting with a diagnosis of either anorexia nervosa or bulimia, using the Mini International Neuropsychiatric Interview (MINI), DSM IV version.

RESULTS:

While univariate analyses show that nearly all anxiety disorders are related to major depressive episode (MDE), a separate analysis of each anxiety disorder reveals that they do not all have the same influence in terms of risk of onset of MDE in anorexics and bulimics, when adjusted for univariate variables related to MDE (subjects' age, ED duration, prior incidents of anorexia nervosa in BN subjects, inpatient or outpatient status, nutritional state). Current generalized anxiety is significantly related to lifetime presence of MDE in AN subjects, and to current MDE in AN and BN subjects. Generalized anxiety is the most frequent disorder in AN and BN subjects to according our study; it also appears to be one of the principal predictive factors for MDE, which is 2.4 to 4.2 times more frequent when GAD is present. Diagnosis of OCD has its own particular effect on lifetime risk for MDE in AN subjects, regardless of GAD: it increases the risk of depression by 3.5. It is one of the most frequent anxiety disorders among AN subjects, present in nearly a quarter of them. In bulimics, when GAD is excluded, two factors are related to current diagnosis of MDE: panic disorder and subjects' inpatient or outpatient status. Hospitalized bulimics are diagnosed with current MDE 4.4 times more often than those seen as.
