[Are anxiety or depressive disorders more frequent among one of the anorexia or bulimia nervosa subtype?].
Our objective was to answer the following question: are there differences between diagnostic groups of eating disorders (ED) for the prevalence of depressive and anxiety disorders, when clinical differences between the groups are taken into account (ie age of subjects, ED duration, inpatient or outpatient status, and Body Mass Index)?


METHODS
We evaluated the frequency of anxiety disorders and 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. We compared the prevalences between sub-groups of anorexics (AN-R and AN-BN), between sub-groups of bulimics (BN-P and BN-NP) and between anorexics and bulimics while adjusting for the variables defined below.


RESULTS
Current or lifetime comorbidity of anxiety and depressive disorders did not differ between AN-Rs and AN-BNs, nor between BN-Ps and BN-NPs. Only current diagnoses of agoraphobia and obsessive-compulsive disorder were significantly more frequent in anorexics than in bulimics.


CONCLUSIONS
The greater frequency of comorbidity between obsessive-compulsive disorder and AN compared to BN, already well documented, is not questioned. The remaining anxiety disorders are equally frequent among all the diagnostic types of ED.
