    Objective: Eating Disorder Not Otherwise Specified (EDNOS) constitute the most common eating disorder among those seeking treatment at eating disorder facilities; they are even more common among persons with eating disorders the community. This study compares the impact of applying the revised diagnostic criteria proposed by the DSM-5 workgroup, and the broad categories for the diagnosis of eating disorders (BCD-ED) proposed by Walsh and Sysko on the prevalence of EDNOS. Method: In two nationwide epidemiological studies the prevalence of eating disorders among female high school (n = 2,028) and university students (n = 1,020) was examined using DSM-IV criteria. We used a two-stage design, administering a questionnaire in the first stage and an interview in the second stage. Results: In the combined samples 118 cases of eating disorders (DSM-IV) were detected, of which 86 were diagnosed as EDNOS (72.9%). Application of the DSM-5 criteria reduced the number of EDNOS cases to 60 (50.8%) or to 52 (44%), when using a BMI
