New research links premature birth to mom’s risk of heart disease later in life

preemie and momThis headline has raised concerns among women who have had a premature baby (birth before 37 weeks) – and for good reason.

In a published study, researchers analyzed data from more than 70,000 women to look at the association between premature delivery and future cardiovascular disease (CVD). They found that women who delivered a baby before 37 weeks gestation in their first pregnancy had a 40 percent greater risk of heart disease later in life, compared to women with term deliveries. This finding occurred even after accounting for pre-pregnancy sociodemographic, lifestyle, and CVD risk factors.

And there’s more.

Women who delivered before 32 weeks gestation had double the risk of CVD later in life compared to women with term deliveries.

So what does this mean for moms who gave birth early?

The results from the study are concerning, but researchers have stated that premature delivery may be an early warning sign of future heart problems, but not the cause of them. Factors such as pre-eclampsia and gestational diabetes, both of which can cause preterm labor, are already considered risk factors for future CVD. More research is needed to determine exactly how premature delivery and CVD are linked.

The March of Dimes funds research to help discover the causes of preterm labor and premature birth. In about half of cases, the cause is unknown. We hope that with our groundbreaking research, we will be able to help prevent premature birth and improve the health of mothers and babies throughout their lifetimes.

If you have questions or concerns about your future risk of CVD, speak with your health care provider.
