About the trial

What the trial wants to find out

The overarching intention of the Eating Disorder Genetics Initiative 2 (EDGI2) is to increase sample size, diversity, and eating disorder phenotypes. The investigators are enrolling 20,000 new participants with anorexia nervosa (AN), bulimia nervosa (BN), binge-eating disorder (BED), avoidant/restrictive food intake disorder (ARFID), and controls in the US, Mexico, Australia, New Zealand, Sweden, and Denmark. A primary study goal is to enroll at least 30% of participants from underrepresented groups. Participants are asked to complete a series of questionnaires and submit a saliva sample for genotyping. The goal is to better understand eating disorders and how they relate to each other so that better treatments can be developed.
