Epidemiology of eating disorders in persons other than the high-risk group of young Western females.

DOI:10.1097/YCO.0000000000000104 Most studies on the epidemiology of eating disorders have focused on young females in Western countries, being the high-risk group for the development of eating disorders. However, eating disorders do occur in older women and in men and they also do occur in persons in nonwestern countries, as the reviews in this issue show [Raevuori et al. (pp. 426–430), Mangweth-Matzek et al. (pp. 431–435), Pike et al. (pp. 436–442)]. Disordered eating behavior and eating disorders also do occur more frequently among obese people and even more among severely obese people waiting for weight loss surgery than among healthy weight people [Marcus and Wildes (pp. 443–447), Green et al. (pp. 448–452)]. The five articles on eating disorders in this journal review newfindingsoneatingdisordersanddisturbedeating behavior among these nontraditional groups, such as men, older women, persons in nonwestern countries and obese persons [Raevuori et al. (pp. 426–430), Mangweth-Matzek et al. (pp. 431–435), Pike et al. (pp. 436–442), Marcus and Wildes (pp. 443–447), Green et al. (pp. 448–452)]. Last year, the articles in the eating disorder section in this journal addressed the changes in the Diagnostic and statistical manual of mental disorders (5th ed) regarding feeding and eating disorder criteria compared with those in DSM-IV [1,2]. Throughout the DSM-5, the influence of development, sex and culture on the presentation of psychiatric disorders was given more attention than in any previous edition of the DSM [2], which might facilitate the classification of eating disorders among men, older women and among people in nonwestern countries. In DSM-5, the diagnostic criteria for anorexia nervosa and bulimia nervosa were broadened, and binge eating disorder was included as an official diagnostic entity [1]. This has particular relevance for men and older women, whose eating disorder symptoms tend not to fit into stringent categories [Raevuori et al. (pp. 426–430), Mangweth-Matzek et al. (pp. 431–435)]. Compared with DSM-IV, DSM-5 allows more eating disorders
