Eating disorder not otherwise specified (EDNOS) is an eating disorder that does not meet the criteria for anorexia nervosa or bulimia nervosa. Individuals with EDNOS usually fall into one of three groups: sub-threshold symptoms of anorexia nervosa or bulimia nervosa, mixed features of both disorders, or extremely atypical eating behaviors that are not characterized by either of the other established disorders.〔 The symptoms and behaviors of people with EDNOS are similar to those with anorexia and bulimia. People with EDNOS can face the same dangerous risk as people with anorexia and bulimia.〔(【引用サイトリンク】url=http://www.nami.org/Template.cfm?Section=By_Illness&template=/ContentManagement/ContentDisplay.cfm&ContentID=65849 )〕 EDNOS is the most prevalent eating disorder;〔 about 60% of adults treated for eating disorders are diagnosed with EDNOS.〔 EDNOS occurs in all genders.〔 == Characteristics == Rather than providing specific diagnostic criteria for EDNOS, the fourth revision of the ''Diagnostic and Statistical Manual of Mental Disorders'' (DSM-IV) listed six non-exhaustive example presentations, including individuals who: # Meet all criteria for anorexia nervosa except their weight falls within the normal range # Meet all criteria for bulimia nervosa except they engage in binge eating or purging behaviors less than twice per week or for fewer than three months # Purge after eating small amounts of food while retaining a normal body weight # Repeatedly chew and spit out large amounts of food without swallowing # Meet criteria for binge eating disorder Despite its subclinical status in DSM-IV, available data suggest that EDNOS is no less severe than the officially recognized DSM-IV eating disorders. In a comprehensive meta-analysis of 125 studies, individuals with EDNOS exhibited similar levels of eating pathology and general psychopathology to those with anorexia nervosa and binge eating disorder, and similar levels of physical health problems as those with anorexia nervosa. Although individuals with bulimia nervosa scored significantly higher than those with EDNOS on measures of eating pathology and general psychopathology, EDNOS exhibited more physical health problems than bulimia nervosa.〔 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Eating disorder not otherwise specified」の詳細全文を読む スポンサード リンク
