Background
Little population-based data exist on the prevalence or correlates of eating disorders.
Methods
Prevalence and correlates of eating disorders from the National Comorbidity Replication,
a nationally representative face-to-face household survey (n = 9282), conducted in 2001–2003, were assessed using the WHO Composite International
Diagnostic Interview.
Results
Lifetime prevalence estimates of DSM-IV anorexia nervosa, bulimia nervosa, and binge
eating disorder are .9%, 1.5%, and 3.5% among women, and .3% .5%, and 2.0% among men.
Survival analysis based on retrospective age-of-onset reports suggests that risk of
bulimia nervosa and binge eating disorder increased with successive birth cohorts.
All 3 disorders are significantly comorbid with many other DSM-IV disorders. Lifetime
anorexia nervosa is significantly associated with low current weight (body-mass index
<18.5), whereas lifetime binge eating disorder is associated with current severe obesity
(body-mass index ≥40). Although most respondents with 12-month bulimia nervosa and
binge eating disorder report some role impairment (data unavailable for anorexia nervosa
since no respondents met criteria for 12-month prevalence), only a minority of cases
ever sought treatment.
Conclusions
Eating disorders, although relatively uncommon, represent a public health concern
because they are frequently associated with other psychopathology and role impairment,
and are frequently under-treated.

- PreviewFurther analysis has documented two errors in the results reported in the article “The Prevalence and Correlates of Eating Disorders in the National Comorbidity Survey Replication” by Hudson et al., which appeared in Biological Psychiatry (2007;61:348–358). First, the anorexia nervosa lifetime prevalence estimate (standard error) of .6% (.2) reported in Table 1 and the first sentence of the Results section should have been .5% (.2). Second, the results reported in the last row of Table 7 for 12-month treatment of eating disorders among 12-month cases were incorrect.
