BackgroundTo assess the risk of developing Type-1 diabetes among children who were exposed to maternal bereavement during the prenatal or 1-year preconception period.MethodsWe identified N = 1,548,746 singleton births born in Denmark between January 1(st) 1979 through December 31(st) 2004, and their next of kin. Altogether, 39,857 children were exposed to bereavement during their prenatal life. The main outcome of interest was hospitalization for type-1 diabetes (ICD 8: 249; ICD 10: E10).ResultsWe found the strongest association for type-1 diabetes among children exposed to traumatic father or sibling deaths (aIRR: 2.03, 1.22-3.38); the association was mainly seen for girls (aIRR: 2.91, 1.61-5.26).ConclusionsWe found evidence to suggest that female fetuses exposed to severe prenatal stress are at increased risk for developing type-1 diabetes.
