Abstract

We investigated the fetal outcomes of pregnancy in women with pre-existing diabetes in relation to pre-pregnancy risk factors using a community-based cohort of women in Tayside, Scotland. There were 211 pregnancies in 132 women with insulin-requiring type 1 and 2 diabetes between January 1993 and December 2005. Adverse fetal outcome was classified as spontaneous miscarriage, termination for medical reasons, stillbirth, neonatal death, or congenital malformation and occurred in 61 (29%) pregnancies. Mothers with poor glycemic control pre-conceptually and at booking (HbA(1c)=7.5%) had almost a three-fold increase in adverse fetal outcome compared with mothers having fair control, odds ratio (OR) 2.59 (95% CI 1.11-6.03), and 2.71 (95% CI 1.39-5.28), respectively. Mothers who were still smoking at the booking visit had a two-fold increase in adverse fetal outcome (OR 2.12, 95% CI 1.09-4.10). Further improvement in the management of diabetes and pregnancy is needed through enhanced preconception services addressing the full spectrum of modifiable risk factors.
