Ever experienced an eating disorder? Kua mate mai anō tētahi mate kai?


Please take our survey to help us understand more about these devastating illnesses & make a genuine contribution to the diagnosis, management & treatment of eating disorders.

Volunteers Needed for a Control Group If you are 16 years or old, have never experienced an eating disorder, you can help!

Please complete our survey. If you are eligible we will send you a spit kit to provide a DNA sample.
We will compare the differences in the genetic code of people with and without eating disorders, but we need a control group to do this.

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.
