- •Late preterm occurring in women with GDM does not confer an increased risk for neonatal complications.
To assess pregnancy outcome among women with gestational diabetes mellitus (GDM) delivering at the late preterm period.
Retrospective observational cohort of all women with GDM who delivered a singleton fetus at the late preterm birth period (34 + 0/7 to 36 + 6/7 weeks of gestation). The study group included all women diagnosed with GDM and were compared to a control group of women delivering at the same gestational age period but without known GDM.
1849 women were included in the study, of whom 132 (7.1%) were diagnosed with GDM and 1717 (92.9%) were not. Women with GDM had a lower rate of spontaneous vaginal delivery (45.5% vs. 62.9%, p < 0.001) and a higher rate of cesarean delivery (50.8% vs. 31.8%, p < 0.001). GDM diagnosis incurs an adjusted ratio of 1.82 for cesarean delivery (95% CI 1.24–2.66, p = 0.002). Neonates of mothers with GDM had significant higher mean birth weight and birth weight percentile, including higher rate of large-for-gestational age newborns. There were no differences in mortality or other parameters for neonatal morbidity.
according to our data, late preterm occurring in women with GDM does not confer an increased risk for neonatal complications.
