Epidemiology and Demographics

Prevalence

The 12-month prevalence of anorexia nervosa is 400 per 100,000 (0.4%) of the overall population in young females.[1] The majority of research into the incidence and prevalence of anorexia has been done in Western industrialized countries, so results are generally not applicable outside these areas.

Gender

The condition largely affects young adolescent females, with females between 15 and 19 years old making up 40% of all cases. Furthermore, the majority of cases are unlikely to be in contact with mental health services. As a whole, about 90% of people with anorexia are female.[2]
