Abstract

Objective: Eating Disorders Not Otherwise Specified (EDNOS) represent the most common eating disorder diagnosed in specialized treatment settings. The purpose of the current study is to assess the prevalence of EDNOS in a nationwide community sample. Method: Participants were 2,028 female students, aged 12–23, attending public schools in the 9th to 12th grades in Portugal. Participants completed the Eating Disorder Examination Questionnaire in Stage 1 of the study. In Stage 2, we selected all the participants who met any of these criteria: (1) BMI ≤17.5, (2) scores ≥4 on any of the four EDE‐Q Subscales, (3) a total EDE‐Q score ≥4, or (4) the presence of dysfunctional eating behaviors. In Stage 2, eating disorder experts interviewed 901 participants using the Eating Disorder Examination. Results: The prevalence of all eating disorders was 3.06% among young females. Prevalence for anorexia nervosa was 0.39%, for bulimia nervosa 0.30%, EDNOS 2.37%. Conclusion: EDNOS is a very common eating disorder and accounts for three‐quarters of all community cases with eating disorders. © 2006 by Wiley Periodicals, Inc. Int J Eat Disord 2007

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
