Abstract

Objective: While antenatal corticosteroids reduce the risk of neonatal morbidity and mortality, perhaps the maternal hyperglycemia they produce has other neonatal effects. Thus, we sought to examine the association between antenatal betamethasone exposure and neonatal hypoglycemia and hyperbilirubinemia. Methods: We designed a retrospective cohort study of all preterm deliveries from 32 to 37 weeks of gestation at a single university hospital from 1990 to 2007. Data were collected on antenatal betamethasone administration and the neonatal outcomes. Univariable, multivariable and stratified analyses were conducted. Results: Of 6675 preterm deliveries, significantly higher rates of neonatal hypoglycemia (5.7% versus 4.2%, p<0.05) and hyperbilirubinemia (45.9% versus 24.1%, p<0.05) were observed in neonates exposed to antenatal betamethasone. Controlling for potential confounders including gestational age, these findings persisted with betamethasone-exposed neonates 1.6 times more likely to have hypoglycemia (aOR 1.60, 95% CI 1.24-2.07) and 3.2 times more likely to have hyperbilirubinemia (aOR 3.23, 95% CI 2.92-3.58). Conclusions: Antenatal betamethasone was associated with neonatal hypoglycemia and hyperbilirubinemia. Further work to determine whether this association is related to maternal hyperglycemia should be conducted, given this could be addressed with strict maternal glycemic control during betamethasone administration.
