Epidemiology

It is a common misconception that eating disorders are restricted only to women, and this may have skewed research disproportionately to study female populations. In the developed world, binge eating disorder affects about 1.6% of women and 0.8% of men in a given year. Anorexia affects about 0.4% and bulimia affects about 1.3% of young women in a given year. Up to 4% of women have anorexia, 2% have bulimia, and 2% have binge eating disorder at some point in time. Anorexia and bulimia occur nearly ten times more often in females than males. Typically, they begin in late childhood or early adulthood. Rates of other eating disorders are not clear. Rates of eating disorders appear to be lower in less developed countries.

In the United States, twenty million women and ten million men have an eating disorder at least once in their lifetime.
