Which factor can increase the risk of preterm labor?

High maternal age is a significant factor that can increase the risk of preterm labor. As women age, particularly those over 35, they may experience a variety of physiological changes that can affect pregnancy outcomes. Increased risk of chronic health conditions, changes in the uterine structure, and potential complications in pregnancy are common concerns associated with advanced maternal age. Additionally, older mothers may have more difficulty managing existing health issues or may be at a higher risk for complications such as gestational diabetes or hypertension, which can contribute to the likelihood of preterm labor.

In contrast, increased physical activity is generally associated with beneficial effects during pregnancy, improving overall health and potentially reducing the risk of preterm labor when done within appropriate guidelines. Regular prenatal check-ups are crucial for monitoring both maternal and fetal health, and they can help to identify and mitigate any risks early on. Low maternal stress levels tend to have a protective effect on pregnancy, as high stress is more closely linked to adverse outcomes, including preterm labor. Thus, factors like high maternal age are particularly important to consider when assessing the risks of preterm labor.
