Summary
Brief summary
The Trial to Reduce IDDM in the Genetically at Risk (TRIGR) is an international effort to
conduct a primary prevention nutrition trial for type 1 (insulin-dependent) diabetes. The
TRIGR study is targeted at newborns who are at genetic risk for type 1 diabetes because their
mother, father and/or full sibling has type 1 diabetes. All families are encouraged to breast
feed their infants for as long as possible. Prior to birth, the child is randomly assigned to
receive one of two infant formulas, should formula be required prior to 8 months of age. The
study will determine whether weaning to a possibly protective infant formula decreases these
children's chances of developing diabetes - as it does in the animal models for diabetes.
