BACKGROUND AND AIM: To determine pregnancy outcome in women with type 1 and type 2 diabetes. METHODS AND RESULTS: A prospective study was conducted in 33 centers in Italy between 1999 and 2003, mainly recording preterm delivery, stillbirths, neonatal mortality, congenital malformations and birthweight. Of the 668 women examined, 504 had type 1 diabetes and 164 had type 2. Pre-pregnancy counseling had been provided to 43.9% of the women who had type 1 diabetes and 29.1% of the women who had type 2 diabetes and correlated with a better HbA1c value throughout pregnancy. The preterm delivery rate was significantly higher in type 1 and 2 diabetics than in normal pregnant women and was related to HbA1c values higher than 8%, gestational hypertension, pre-eclampsia and the presence of retinopathy before pregnancy. The stillbirth and neonatal mortality rates were also higher in diabetic pregnant women (1.26% and 0.63%, respectively) than in Italian pregnancies in general (0.30% and 0.32%), and the same was true for major congenital malformations (4.9% for diabetic pregnancies, 0.86% for normal Italian pregnancies). CONCLUSIONS: In our population, pregnancy in diabetic women was still associated with a high rate of stillbirths, neonatal mortality and congenital malformations. Unplanned pregnancies and non-optimal glycemia control may help explain the high rates of maternal and neonatal complications.

Abstract

BACKGROUND AND AIM: To determine pregnancy outcome in women with type 1 and type 2 diabetes. METHODS AND RESULTS: A prospective study was conducted in 33 centers in Italy between 1999 and 2003, mainly recording preterm delivery, stillbirths, neonatal mortality, congenital malformations and birthweight. Of the 668 women examined, 504 had type 1 diabetes and 164 had type 2. Pre-pregnancy counseling had been provided to 43.9% of the women who had type 1 diabetes and 29.1% of the women who had type 2 diabetes and correlated with a better HbA1c value throughout pregnancy. The preterm delivery rate was significantly higher in type 1 and 2 diabetics than in normal pregnant women and was related to HbA1c values higher than 8%, gestational hypertension, pre-eclampsia and the presence of retinopathy before pregnancy. The stillbirth and neonatal mortality rates were also higher in diabetic pregnant women (1.26% and 0.63%, respectively) than in Italian pregnancies in general (0.30% and 0.32%), and the same was true for major congenital malformations (4.9% for diabetic pregnancies, 0.86% for normal Italian pregnancies). CONCLUSIONS: In our population, pregnancy in diabetic women was still associated with a high rate of stillbirths, neonatal mortality and congenital malformations. Unplanned pregnancies and non-optimal glycemia control may help explain the high rates of maternal and neonatal complications.
