Eating disorders (eg, binge eating disorder, bulimia nervosa, and anorexia nervosa) are a group of psychiatric conditions defined as a disturbance in eating or eating-related behaviors that impair physical or psychosocial functioning. According to large US cohort studies, estimated lifetime prevalences for anorexia nervosa, bulimia nervosa, and binge eating disorder in adult women are 1.42%, 0.46%, and 1.25%, respectively, and are lower in adult men (anorexia nervosa, 0.12%; bulimia nervosa, 0.08%; binge eating disorder, 0.42%). Eating disorder prevalence ranges from 0.3% to 2.3% in adolescent females and 0.3% to 1.3% in adolescent males. Eating disorders are associated with short-term and long-term adverse health outcomes, including physical, psychological, and social problems.
