Presentation and Course
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.
Importantly, an EDNOS diagnosis may presage future diagnostic crossover into officially recognized eating disorder categories. For example, 40% of individuals with EDNOS go on to develop anorexia nervosa or bulimia nervosa within one to two years.
