Abstract

To study the effect of very advanced maternal age on perinatal outcomes. A retrospective cohort study of women aged 45 years and above, who delivered ≥22 weeks of gestation in a single tertiary center between 1/ 2011 and 12/ 2018. Maternal and neonatal outcomes were compared between women ≥50 years and women of 45-49 years at delivery. Of 83,661 parturients, 593 (0.7%) were 45-49 years old and 64 (0.07%) were ≥50 years old. Obstetrical characteristics were comparable, though the rate of chronic hypertension and preeclampsia with severe features were greater in women ≥50 years (6.2% vs 1.4%, p = 0.04, 15.6% vs 7.0%, p = 0.01, 95% CI 0.19-0.86, respectively). Elective cesarean deliveries were independently associated with advanced maternal age ≥50 (OR 2.63 95% CI 1.21-5.69). Neonatal outcomes were comparable for singletons, but rates of ventilatory support and composite severe neonatal outcomes were higher in twin pregnancies of women ≥50 years (42.8% vs 13.5%, p = 0.01, and 21.4% vs 4.0%, p = 0.03, respectively). Healthy women ≥50 have higher elective cesarean rates, despite similar maternal and neonatal characteristics.
