Transcultural aspects of eating disorders: a critical literature review.

A review of studies addressing anorexia nervosa and bulimia nervosa among Native Americans, African-Americans, Hispanics, Asians, Africans, and Middle Easterners yielded only 35 studies, of which 22 were qualitative case reports, three were clinical quantitative studies, and ten were non-clinical quantitative studies. The case studies reported symptoms similar to those of Caucasian patients, and eating disorders were reported in all SES classes. The clinical studies, all reported from Asian countries, described a number of cases for eating disorders quite different from one another. The non-clinical quantitative studies reported a number of cases consistent with the ranges previously reported for controlled samples of non-clinical Caucasian populations. We found few or no quantitative studies on eating disorders from Hispanic, Middle Eastern, African, or Asian countries other than Japan.
