Since around 1980, in countries belonging to European union the mean maternal age at birth increased by 1.5 y (from 27.1 to 28.6). This demographic change has important consequences on the health of the mother and of the neonate. Maternal mortality rates, stillbirth rates and frequency of congenital anomalies are affected. Without improvement in care those rates would have increased by 15 to 35% because of the increase of the mean age at birth. Nevertheless it should be noted that they continue to decrease.
