The struggle to be thin: a survey of anorexic and bulimic symptoms in a non-referred adolescent population.

Ninety-one per cent of a county-wide high school population (N = 5596) completed the Eating Symptoms Inventory (ESI) and the Eating Attitudes Test (EAT). Being female, older and heavier are far more strongly associated with anorexic and bulimic symptoms than is social class. ESI approximations of the DSM-III criteria for anorexia nervosa or bulimia suggest that while both conditions are rare (less than 1%), bulimia is the more prevalent disorder.
