Eating Disorders & Disordered Eating (an amalgam of recent research):

In a recent study, 27% of Ontario girls 12-18 years old were reported to be engaged in severely problematic food and weight behaviour.

The death rate for eating disorders is high: it ranges between 18% (in 20-year studies) and 20% (in 30-year follow-up studies). In fact, the annual death rate associated with anorexia is more than 12 times higher than the annual death rate due to all other causes combined for females between 15 and 24 years old.
