Maternal and neonatal outcomes in advanced maternal age: a retrospective cohort study

Abstract

Objectives: To describe the effect of extremely advanced maternal age (EAMA) on maternal/neonatal outcomes.Methods: This was a case-control study in which 127 women ≥40 years at the time of delivery out of 2853 singleton hospital deliveries in Ondokuz Mayis University between 1 January 2008 and 31 August 2010 constituted the study group. One hundred and twenty-seven else were chosen randomly out of 2412, 21–35 years old women, via a computer system as controls. Demographic features of 254 mothers and infants as well as maternal and neonatal complications were recorded.Results: Mean maternal age was 41.5 ± 1.9 (40–49) years in EAMA group and 28.9 ± 4.2 (21–35) years in controls. Primigravidity was 19.6% in the EAMA group, whereas 37.8% in controls (p = 0.003). No difference was found between groups according to route of delivery, stillbirth, preterm birth, congenital abnormalities, gender of babies, NICU admission and respiratory problems (for all p > 0.05). A 5th min Apgar score <7 was more frequent in babies born to EAMA mothers compared to controls (9.8% versus 4.9%, p = 0.004).Conclusion: The present study shows that EAMA mothers and their offsprings have similar peri and neonatal risks compared to younger mothers, except lower 5th minute Apgar scores. We conclude that with good perinatal care, EAMA women and their babies can pass through the perinatal period with similar risks of younger women.
