ABSTRACT

OBJECTIVEÛ To evaluate the perinatal outcome and the frequency of maternal complications in pregnancies of women with type 2 diabetes during 1996Ò2001.

RESEARCH DESIGN AND METHODSÛ Medical records of 61 consecutive singleton pregnancies in women with type 2 diabetes from 1996 to 2001 were studied. Pregnancy outcome was compared with that of pregnant women with type 1 diabetes during 1996Ò2000, the background population, and pregnant women with type 2 diabetes during 1980Ò1992 from the same department.

RESULTSÛ The perinatal mortality in pregnancies complicated by type 2 diabetes (4/61, 6.6%) was increased four- and ninefold, respectively, and the rate of major congenital malformations (4/60, 6.7%) was more than doubled, although not statistically significant, compared with type 1 diabetic pregnancies and the background population. The glycemic control was similar or better in women with type 2 diabetes compared with women with type 1 diabetes. Multivariate logistic regression analysis in the pooled group of pregnancies with pregestational diabetes from 1996 to 2001 showed that high HbA1c at admission and type 2 diabetes were independently associated with a serious adverse fetal outcome (perinatal mortality and/or major congenital malformations). The perinatal mortality and the rate of major congenital malformations in type 2 diabetic pregnancies have increased during the last decade.

CONCLUSIONSÛ The perinatal outcome of pregnancies in women with type 2 diabetes during 1996Ò2001 is poor. It is worse than the outcome of pregnancies in women with type 1 diabetes and the background population in the same period, as well as in women with type 2 diabetes studied during 1982Ò1990.
