To compare the pregnancy outcomes in all T1DMP attending at combined (diabetes-obstetric) outpatients clinics in three university teaching hospitals in Dublin from 1995 to 2006 with a non-diabetic control population (C) attending at antenatal outpatient clinics at the same hospitals over the same period.


T1DMP (n = 600) were compared with control non-diabetic pregnancies (n = 142,498).


The spontaneous abortion rate was 15% in T1DMP versus 8% in C (p < 0.0001). Perinatal mortality rate was 3.3% in T1DMP compared to 0.9% in C (p < 0.001). The incidence of foetal macrosomia was 29% in T1DMP versus 16% in C (p < 0.001).


Pregnancy outcomes in T1DMP remain worse than in the general population despite management of T1DMP in combined obstetric/diabetes clinics in a single centre using similar management protocols. These outcomes in our study population of T1DMP in Dublin appear better than some previously reported studies.
