Placebo Comparator: Nonhydrolysed infant formula - Nonhydrolysed cow's milk based infant formula


Other interventions: Hydrolysed infant formula
Participants in the Hydrolysed infant formula -group received the test formula, casein hydrolysate (Nutramigen™, Mead Johnson Nutritionals), not containing antigenic CM protein, whenever breast milk is not available.

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 was 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 were encouraged to
breast feed their infants for as long as possible. Prior to birth, the child was randomly
assigned to receive one of two infant formulas, should formula be required prior to 8 months
of age. The study determined 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.
