Welcome to our EDGI homepage

We have closed our eating disorder survey.

Between March 2020 and March 2023, we received more than 3,500 completed surveys to help us understand more about eating disorders. As of the 31st of March 2023, we have closed our survey as we shift into the project's analysis and interpretation phase. 

We hope to expand our research into eating disorders in the future. If you are interested in being a possible participant for future projects, please use the link below to provide your information.

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.

Are you interested in Avoidant/Restrictive Food Intake Disorder (ARFID)?

From late 2022 till March 2023, we sought opinions from anyone in NZ who had experienced ARFID or their whānau. Our ARFID research priorities questionnaire is now closed. We still welcome new participants for our main EDGI survey, please follow the link at the top of this homepage. 

Please contact hannah.kennedy@otago.ac.nz if you would like to be kept updated on any future ARFID research opportunities from our team.
