Abstract

Objective: To examine the prevalence of antenatal maternal hypoglycemia after initiation of pharmacotherapy for gestational diabetes mellitus (GDMA2) and its association with pregnancy outcomes.

Study design: Retrospective cohort of GDMA2 women receiving either insulin or oral hypoglycemic agents. Composite neonatal outcome included macrosomia, jaundice, respiratory distress syndrome, large for gestational age, shoulder dystocia, birth trauma, 5-minute Apgar < 7, and neonatal hypoglycemia, and was compared between women with and without hypoglycemia using bivariate and multivariate analyses.

Results: Of 489 women included in the study, 95 (19.4%) had at least one episode of hypoglycemia, most often in the setting of glyburide. Newborns exposed to maternal hypoglycemia had higher rates of the composite neonatal outcome (54.7% vs. 38.3%, p = 0.004). After controlling for confounding factors, maternal hypoglycemia remained independently associated with the composite neonatal outcome (aOR = 1.69, 95% CI 1.04-2.72).

Conclusion: Maternal hypoglycemia in GDMA2 was associated with higher rates of adverse neonatal outcomes.
