Anorexia Nervosa Genetics Initiative (ANGI)<\/a><\/h2>\n

The Anorexia Nervosa Genetics Initiative (ANGI), an initiative of The Klarman Family Foundation<\/a>,\u00a0was at the time the largest and most rigorous genetic investigation of eating disorders ever conducted. Dr. Cynthia Bulik at the University of North Carolina at Chapel Hill was the lead investigator of ANGI with collaborators from Karolinska Institutet, Stockholm, Sweden (Dr. Mikael Land\u00e9n), Aarhus University, Aarhus, Denmark (Dr. Preben Bo Mortensen), and Berghofer Queensland Institute for Medical Research, Brisbane, Australia (Dr. Nick Martin) with assistance from the University of Otago, Christchurch, New Zealand (Drs. Martin Kennedy and Jenny Jordan).<\/p>\n

ANGI represented a global effort to detect genetic variation that contributes to this potentially life-threatening illness. In total, ANGI collected biological samples and clinical information from 13,363 individuals with anorexia nervosa as well as healthy controls who were matched by ancestry and geography.<\/p>\n

Recruitment for ANGI is currently closed.<\/p>\n

The ANGI team is grateful to all participants worldwide, to the research teams in the USA, Europe, and Australasia who helped create this unprecedented resource, and to all of the clinicians, researchers, bloggers, journalists, family members, advocates, and individuals with lived experienced who joined us in our collaborative effort to make ANGI a reality.<\/p>\n

Binge Eating Genetics INitiative (BEGIN)<\/a><\/h2>\n

The BEGIN study is no longer enrolling participants and is in the data analysis phase.<\/p>\n

The goal of the BEGIN study was to better understand the genetic factors that may be associated with binge-eating disorder and bulimia nervosa to help us develop better treatments for the millions of people who suffer from these illnesses. Data analysis is still underway.<\/p>\n

Uniting Couples in the Treatment of Eating Disorders (UNITE)<\/a><\/h2>\n

Drs. Cynthia Bulik, Don Baucom, and Jennifer Kirby have developed and tested a suite of interventions for couples in which one or both members is suffering frtom anorexia nervosa, bulimia nervosa, or binge-eating disorder. Dr. Mae Lynn Reyes-Rodr\u00edgez also culturally adapted UNITE for the Latinx population in a treatment called PAS: Promoviendo una Alimentaci\u00f3n Saludable.<\/p>\n

You are now able to access an online training for both basics in couple-based cognitive-behavioral therapy (CBCT) and UNITE in specific. The initial couple-based treatment for anorexia nervosa was called UCAN (Uniting Couples in the treatment of Anorexia Nervosa), but we have united all three interventions under the name UNITE. These trainings are available free of charge at INSERT URL HERE–COMING.<\/p>\n

ARFID Genes and Environment (ARFID-GEN)<\/h2>\n

ARFID-GEN was a research study for individuals aged 18 or older or parents of children (aged 7-17) who currently have avoidant\/restrictive food intake disorder (ARFID) (previously known as selective eating disorder or extreme picky eating). This was the first (and largest) study ever designed to identify genetic and environmental predictors of ARFID. Although ARFID-GEN is not enrolling participants, individuals who are 18 years or older who have had ARFID at any time in their life are welcome to enroll in EDGI2!<\/p>\n
