Melbourne: Australian scientists along with US and Scandinavian researchers are working on a study to determine the genetics behind an eating disorder called Anorexia. The lead investigator on the US component of the study, Cynthia Bulik said that she believed finding a genetic basis for eating disorders will be a big step in increasing that number. "Studies have shown fairly unequivocally that genes play a role in anorexia nervosa," said Bulik, "Somewhere between 40 and 60 per cent of liability to the disorder is due to genetic factors" she added. Anorexia nervosa is an eating disorder characterised by immoderate food restriction and irrational fear of gaining weight, and perception of having a distorted body.
