Maternal and Neonatal Outcomes in Korean Women with Type 1 and Type 2 Diabetes

BACKGROUND: The purpose of this study was to evaluate maternal and neonatal outcomes in Korean women with type 1 diabetes and type 2 diabetes. METHODS: We performed a retrospective survey of 163 pregnancies in women with type 1 diabetes (n=13) and type 2 diabetes (n=150) treated from 2003 to 2010 at Cheil General Hospital & Women's Healthcare Center, Korea. We compared maternal characteristics as well as maternal and neonatal outcomes between groups. RESULTS: Differences in glycosylated hemoglobin between type 1 and type 2 diabetes were not significant. Birth weight (3,501±689.6 g vs. 3,366±531.4 g) and rate of major congenital malformations (7.7% vs. 5.6%) were not significantly different. However, women with type 1 diabetes had higher rates of preeclampsia (38.5% vs. 8.2%, P=0.006), large for gestational age (LGA; 46.2% vs. 20.4%, P=0.004), macrosomia (38.5% vs. 13.4%, P=0.032), and admission for neonatal care (41.7% vs. 14.8%, P=0.03) than women with type 2 diabetes. CONCLUSION: Maternal and neonatal outcomes for women with type 1 diabetes were poorer than for women with type 2 diabetes, especially preeclampsia, LGA, macrosomia and admission to the neonatal intensive care unit.
