SGA birth rates had an inverse relationship with maternal age; that is, the rates decreased as the mother’s age group increased.
Similarly, mothers age 15 to 19 had the lowest large for gestational age (LGA) birth rates. LGA rates during this period increased with maternal age and were highest among mothers age 40 to 49.
Preterm birth rates were highest among mothers age 40 to 49, and lowest among mothers age 25 to 29.
