Overview
Prevalence
The 12-month prevalence of anorexia nervosa is 400 per 100,000 (0.4%) of the overall population in young females.
Epidemiology and Demographics
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. However, recent reviews[1][2] of studies on the epidemiology of anorexia have suggested an incidence of between 8 and 13 cases per 100,000 persons per year. These studies also confirm the view that 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.[3]
