what are the groups affected by anorexia?

In the United States, eating disorders appear to be about as common in young Hispanic women as in Caucasians, more common among Native Americans, and less common among blacks and Asians. However, several studies in the Southeastern United States have shown that many eating disorder behaviors are even more common among African American women than others. Black women are more likely to develop bulimia nervosa than anorexia nervosa and are more likely to purge with laxatives than by vomiting.
