Preterm birth, or the delivery of a baby before 37 weeks of gestation, is a major public health concern. It is a leading cause of neonatal mortality and morbidity, and it affects 1 in 10 pregnancies globally.
However, preterm birth is not only a risk factor for adverse outcomes in newborns but also a risk factor for the long-term health of mothers. Recent studies have shown that women who give birth preterm may have an increased risk of developing cardiovascular diseases later in life.
What is Cardiovascular Disease?
Cardiovascular disease (CVD) refers to a group of conditions that affect the heart and blood vessels. It includes diseases such as coronary artery disease, heart failure, stroke, and peripheral artery disease.
CVD is a leading cause of death and disability worldwide and is responsible for 31% of all deaths globally.
The Link Between Preterm Birth and Cardiovascular Risks
According to a growing body of research, women who give birth preterm may face a higher risk of developing cardiovascular disease later in life.
A study published in the Journal of the American College of Cardiology found that women who gave birth preterm had a 40% higher risk of developing cardiovascular disease than women who gave birth at full term. This risk persisted even after adjusting for other risk factors such as age, smoking status, and hypertension.
Another study published in the journal Circulation found that women who delivered preterm had higher rates of hypertension, diabetes, and dyslipidemia, which are all risk factors for cardiovascular disease.
The study also found that the risk of developing cardiovascular disease was higher in women who had more than one preterm delivery.
Possible Mechanisms
Several mechanisms may explain the link between preterm birth and cardiovascular risks in mothers. One possible explanation is that preterm birth may cause changes in the maternal cardiovascular system that persist long after delivery.
For example, preterm birth may lead to endothelial dysfunction, which is a precursor to atherosclerosis and other cardiovascular diseases. It may also cause changes in cardiac structure and function.
Another possible mechanism is that preterm birth may be a marker for underlying maternal health conditions that increase the risk of cardiovascular disease.
For example, women who give birth preterm may be more likely to have hypertension, diabetes, and obesity, which are all risk factors for cardiovascular disease.
Prevention and Management
Preventing preterm birth is critical not only in improving neonatal health outcomes but also in reducing maternal long-term health risks.
Pregnant women can reduce their risk of preterm birth by getting early and regular prenatal care, avoiding substance use and tobacco exposure, and managing chronic conditions such as hypertension and diabetes.
For women who have had a preterm delivery, it is important to assess their cardiovascular risk and manage any underlying health conditions.
This may include monitoring blood pressure, blood sugar, and cholesterol levels, and addressing lifestyle factors such as smoking and diet.
Conclusion
Preterm birth is a significant public health issue that affects both neonatal and maternal health.
Women who give birth preterm may face a higher risk of developing cardiovascular disease later in life, and this risk may persist even after adjusting for other risk factors. Understanding the link between preterm birth and cardiovascular risks is critical in improving maternal health outcomes and reducing the burden of cardiovascular disease worldwide.
