Main Findings
This analysis demonstrates the increased risk of hypoglycaemia in neonates exposed to antenatal corticosteroids but born at term. This applies in those exposed remote from birth because of a perceived risk of preterm birth; it also applies in those exposed prior to planned early term caesarean section. The risk is particularly high in pregnancies affected by diabetes. We also suggest an increasing risk of hypoglycaemia with decreasing corticosteroid-to-birth interval. After adjustment for covariates, no association with the use of ventilation or CPAP was found.
