Most cases of severe disorder are found in young, affluent, white females in competitive environments. The central characteristic of these related disorders is an overwhelming, all-encompassing drive to be thin. As many as 20% in anorexia die from disorder, with about 50% resulting from suicide: the mortality rate from eating disorders is the highest for any psychological disorder, even depression. Bulimia had a large increase between 1981-82. One of the most prevalent psychological disorders on college campuses: there has never been as much stress, anxiety, etc, until now.

Bulimics show an over-concern with body shape.
