When researchers followed a group of 496 adolescent girls for 8 years, until they were 20, they found:
5.2% of the girls met criteria for DSM5 anorexia, bulimia, or binge eating disorder.
When the researchers included nonspecific eating disorder symptoms, a total of 13.2% of the girls had suffered from a DSM-5 eating disorder by age 20. (NEDA)
BDD appears to be relatively common. Epidemiologic studies have reported a point prevalence of 0.7% to 2.4% in the general population. These studies suggest that BDD is more common than disorders such as schizophrenia or anorexia nervosa.
