About EDGI2

The researchers behind the globally successful Eating Disorder Genetics Initiative (EDGI) in 2020 have now launched EDGI2!

EDGI2 is the world’s largest genetic investigation into eating disorders ever performed, with a fourth eating disorder now included – Avoidant Restrictive Food Intake Disorder (ARFID).

Researchers have only scratched the surface in understanding the causes of eating disorders.

The Australian arm of EDGI2 aims to further identify the dozens of genes that influence a person’s risk of developing the complex, devastating illness of anorexia nervosa, bulimia nervosa, binge-eating disorder and ARFID, to improve treatment, and ultimately save lives.

Groundbreaking research aims to identify the genes that influence a person’s risk of developing an eating disorder and improve treatment outcomes:

Who can participate?

Any Australian aged 18 years and over who is currently living with, or has experienced at any point in their lives anorexia nervosa, bulimia nervosa, binge eating disorder, and avoidant restrictive food intake disorder (ARFID) can participate in the study.
