Maternal age refers to the age of a woman at the time she gives birth. It is an important factor in pregnancy and can influence both maternal and infant health. Generally, women in their 20s and early 30s are considered to have lower risks for complications compared to older mothers. As maternal age increases, particularly after age 35, there may be higher risks for certain conditions, such as gestational diabetes and chromosomal abnormalities in the baby. Healthcare providers often monitor pregnancies more closely for older mothers to ensure the health and safety of both the mother and the child.
