Pregnancy outcomes at advanced maternal age in a tertiary Hospital, Jeddah, Saudi Arabia

To evaluate obstetrical and fetal outcomes among advanced maternal age (AMA) women.

Retrospective cohort study carried out at a teaching hospital, Jeddah, Saudi Arabia, during 18 years period (from January 2003 until December 2020). A total of 79095 women gave birth, and randomized block was used to include 4318 singleton pregnancy women (>28 gestational weeks), of them 2162 age ≥40 years. Associations between AMA and obstetrical and fetal parameters were assessed.

Advanced maternal age independently associated with non-Saudi national, mother's weights 80-99 kg, diabetes mellitus, and hypertension. Advanced maternal age mothers were more liable to premature rupture of membranes (PROM), caesarean (CS) deliveries, and postpartum hemorrhage. Newborn of AMA women were at high risk of birth weight <2500 g, birth weight 3600-4500 g, decline Apgar score at 5 minutes, and neonatal intensive care unit (NICU) admissions.

Advanced maternal age is an independent risk factor for adverse obstetric hazards as CS, antepartum haemorrhage, diabetes mellitus, hypertension, PROM, postpartum hemmorage, and fetal complications as low birth weight, macrosomia, NICU admission, congenital anomalies, and low Apgar score. These results must be carefully considered by maternal care providers to effectively improve clinical surveillance.
