Overview, Causes, & Risk Factors
The exact cause of this disorder is not known, but social attitudes towards body appearance and family factors are believed to play a role in its development. The condition usually occurs in adolescence or young adulthood. It is more common in women, affecting 1-2% of the female population and only 0.1-0.2% of males.
Anorexia is seen mainly in Caucasian women who are high academic achievers and have a goal-oriented family or personality. Some experts have suggested that conflicts within a family may contribute to anorexia. It is thought that anorexia is a way for a child to draw attention away from marital problems, for example, and bring the family back together.
Other psychologists have suggested that anorexia may be an attempt by young women to gain control and separate from their mothers. The causes, however, are still not well understood.
