Outcome of Pregnancies Complicated by Type 1 Insulin-Dependent Diabetes in Sweden: Acute Pregnancy Complications, Neonatal Mortality and Morbidity

Abstract

This prospective nationwide study conducted during 1982-1985 examined the rates of hypertensive disorders, perinatal mortality and morbidity in 491 insulin-dependent diabetic pregnancies (White's classes: B, 164; C, 129; D, 172; F, 26) and in the total population of 279,000. The rates of pregnancy-induced hypertension (PIH) or pre-eclampsia (20.6%), premature delivery (24.6%), and cesarean section (45.2%) in the diabetic group were more than four times higher than normal. PIH or preeclampsia occurred significantly (p 1c values in early pregnancy independently of each other had a significant impact on the occurrence of neonatal morbidity.
