This study specifies placental and neonatal percentage growth trajectories in different maternal age groups. One of the most important factors for successful pregnancy outcome is maternal age. Extreme maternal age adversely affects fetal and placental growth patterns.
This study was conducted on 391 placentas obtained from her 6-month consecutive deliveries from the obstetrics and gynecology department of a teaching hospital in North Karnataka, India.
The age distribution of the 391 mothers shows a mean of 23.6 years and a standard deviation of 3.7 years, with 7.2% under her 20s and 7.6% over her 30s. Birth weight percentiles and placental morphometry did not show a consistent association with increased maternal age. This study showed a consistent increasing trend in birth weight percentiles for different maternal age groups only in the higher percentiles (75th to 95th), whereas placental morphometric percentiles showed no consistent relationship with age. Placental morphometric percentiles showed no consistent relationship with maternal age except for placental weight at the 5th and 50th percentiles and placental surface area at the 25th percentile.
