Identified eating disorders include anorexia nervosa, bulimia nervosa, and binge-eating disorder. These disorders are not always distinct, and many individuals exhibit symptoms of more than one. Their prevalence has increased during the latter twentieth and early twenty-first centuries. According to the National Eating Disorders Association (NEDA) in 2021, it was estimated that around twenty million women and ten million men in the United States would have an eating disorder at some point in their lives. Anorexia and bulimia predominantly affect adolescent and young adult women. However, they can also occur in men and older adults, and binge-eating disorder occurs more frequently in men. The rising incidence of eating disorders in men is most commonly associated with sports (such as wrestling), bodybuilding, and the performing arts (such as dance). The disorders can be chronic and recur across the life span of an individual. Recognition of eating disorders in older people has increased, as have the negative health effects of the conditions on this population.
