In anorexia nervosa,the eating disorder (ED) is the cause of thinness. In severe obesity, the overweight is a symptom. This symptom, however, is only the consequence of possibly deregulated eating behavior. The literature, focusus a specified ED of DSM-V: Binge Eating Disorder (BED) or Binge Eating, whom estimated prevalence in the severely obese population varies from 1.4 to 49% depending on the studies. The other ED, called unspecified ED (or EDNOS for Eating Disorder Non Otherwise Specified in the English literature), are much less known.

The main objective of this study is to assess the prevalence rate of unspecified ED (EDNOS or "non-BED ED") in subjects with severe obesity (BMI> 35) consulting for medical or surgical management in a General Hospital Center CSO (Specialized Obesity Center) using an adapted version of the QEWP-R, called the QEWP-RA.

When it comes to weight problems, no one today disputes with anorexia nervosa that thinness is only a symptom. Thinness is the consequence of a multifactorial food restriction, in other words the consequence of an Eating Behavior Disorder (ED). The diagnosis of anorexia nervosa is made relative to the presence of diagnostic criteria listed in the DSM-V (Diagnostic and Statistical Manual V). Everyone recognizes the need for multidisciplinary care that is not limited to the prescription of re-nutrition. Imposing an increase in energy intake has never been enough to cure patients with anorexia. The multidisciplinary support offered to these subjects also seeks to understand and treat the biopsychosocial determinants that perpetuate the mechanisms of food restriction and most of the therapeutic support is based on a psychotherapeutic, individual and / or family approach. The excess weight of subjects with severe obesity (Body Mass Index> 35) suffers from a lower etiopathogenic consideration. In obese people, excess weight is, too often, considered more as the problem to be treated than as the consequence of a more complex problem. Thus, the main therapeutic means still currently used are based on simplistic thermodynamic fundamentals and are based on an imposed food restriction (diet) or even undergone (bariatric surgery procedures).

The main objective of this study is to assess the prevalence rate of unspecified ED (EDNOS or "non-BED ED") in subjects with severe obesity (BMI> 35) consulting for medical or surgical management in a General Hospital Center CSO (Specialized Obesity Center) using an adapted version of the QEWP-R, called the QEWP-RA (questionnaire on eating and weight pattern-revised and modified).

The primary endpoint will be the prevalence rate of ED not specified in the QEWP-RA.
