Anorexia could be genetic says international study:

A researcher at a US clinic says that a decade-long study into anorexia nervosa is beginning to reveal that those who suffer from the disease might have a genetic predisposition toward it. The study,known as the Genetics of Anorexia Nervosa collaboration, is conducted in eight cities in North America,including Tulsa,and two European cities. It is funded by the National Institutes of Health. Researcher Craig Johnson said that if a person has a family member who has had anorexia nervosa, she or he is 12 times more at risk of developing the illness. "Genetics loads the gun. Enviornment pulls the trigger," said Johnson, the director of the eating disorders unit at Laureate Psychiatric Hospital in Tulsa and one of the study's principal researchers.
