This review discusses the incidence, prevalence, and mortality rates of eating disorders, focusing on anorexia nervosa (AN), bulimia nervosa (BN), eating disorder not otherwise specified (EDNOS), and binge eating disorder (BED). Anorexia nervosa is relatively common among young women, with an increasing incidence in 15-19 year-old girls, though it remains stable overall. Bulimia nervosa may have decreased since the early 1990s. All eating disorders have elevated mortality risks, with AN having the highest rate. Binge eating disorder is more common among males and older individuals. The review highlights methodological issues in epidemiological studies, such as the under detection of eating disorders in the general population due to patients' denial or concealment of their illness. The article also discusses the proposed changes in diagnostic criteria for eating disorders in the DSM-5, which aim to reduce the size of the EDNOS category and broaden the criteria for AN and BN.This review discusses the incidence, prevalence, and mortality rates of eating disorders, focusing on anorexia nervosa (AN), bulimia nervosa (BN), eating disorder not otherwise specified (EDNOS), and binge eating disorder (BED).
