Australian teenagers as young as 14 are taking extreme measures including vomiting or taking laxatives to control their weight.
A new government study found, while a very small minority of mid-adolescents met the criteria for anorexia or bulimia, significant numbers had taken action to try and control their weight.
The Growing Up In Australia Longitudinal Study of Australian Children found girls were more worried about their weight than boys, and many considered their weight an important measure of how they felt about themselves.
