NZ researchers seeking 3,500+ volunteers for world’s largest eating disorders genetics investigation  

The Eating Disorders Genetics Initiative (EDGI) is the world's largest genetic investigation into eating disorders ever performed. The local arm of EDGI aims to identify hundreds of genes that influence a person’s risk of developing anorexia nervosa, bulimia nervosa & binge-eating disorder in order to improve treatments, &, ultimately save lives.

Have you, or has someone you care about ever experienced Avoidant/Restrictive Food Intake Disorder (ARFID)?

We are currently inviting people to tell us which ARFID research topics are most important to them to help us guide future research that is meaningful to the ARFID community.

The study is open to anyone who has experienced ARFID personally, or their whānau and is at least 16 years of age. A clinical ARFID diagnosis is not required. You must also be currently residing in New Zealand.
