Offspring of diabetic pregnancy: short-term outcomes

Abstract

In spite of clinicians apparently appreciating the risks of maternal diabetes to the baby, babies of mothers with diabetes are still at increased risk compared to those of non-diabetic women. The rate of prematurity in infants of diabetic mothers is five times that of the general population. Women with pre-gestational diabetes give birth to larger babies. In a recent study, half were above the 90th centile for weight. The postnatal management of these babies continues to give cause for concern. In a recent UK study, over half of all infants of diabetic mothers were admitted to a neonatal unit. One-third of these were at term. This admission rate is three times the UK average and examination of cases showed that two-thirds of admissions were unnecessary. It is likely that a high maternal blood glucose concentration is the most important factor causing this increased risk. Babies of women with type 1 and type 2 DM have similar complication rates. Tighter preconceptional glycaemic control as well as during the pregnancy is likely to be important in improving outcome for the babies of diabetic mothers.
