Prevalence
Although EDNOS (formerly called “atypical eating disorder”) was originally introduced in DSM-III to capture unusual cases, it is now the most commonly diagnosed eating disorder. Specifically, EDNOS accounts for approximately 40% to 60% of cases in eating disorder specialty clinics, and up to 90% of eating disorder diagnoses conferred in non-specialty psychiatric settings. The lifetime prevalence of EDNOS in the National Comorbidity Survey Replication, a large epidemiological study that interviewed a nationally representative sample of U.S. residents, was 4.64% among adults and 4.78% among adolescents. EDNOS is an especially prevalent category in populations that have received inadequate research attention such as young children, males, ethnic minorities, non-Western groups, and the elderly.

“That the public can grow accustomed to any face is proved by the increasing prevalence of Keith’s ruined physiognomy on TV documentaries and chat shows, as familiar and homely a horror as Grandpa in The Munsters.”
—Philip Norman, British author, journalist. The Life and Good Times of the Rolling Stones, introduction (1989)
“The prevalence of suicide, without doubt, is a test of height in civilization; it means that the population is winding up its nervous and intellectual system to the utmost point of tension and that sometimes it snaps.”
