New research suggests that heart disease risk may start in the womb, with pregnancy complications linked to poorer cardiovascular health in offspring over 20 years later.
A recent study has found that a child's future heart health may be partially shaped before they are born, with pregnancy complications linked to poorer cardiovascular health in offspring more than 20 years later. The study, published in JAMA Network Open, found that young adults whose mothers had high blood pressure during pregnancy had more signs of early arterial injury, higher blood pressure, higher body mass index, and higher blood sugar than their peers.
The researchers evaluated nearly 1,350 mother-child pairs from the Future of Families and Child Well-Being Study, which enrolled mothers and children at birth between 1998 and 2000 across 20 U.S. cities. The children were then followed into adulthood, and their cardiovascular health was assessed at age 22 using blood pressure measurements, blood testing, body mass index assessments, and carotid artery ultrasounds. The scientists compared participants with and without exposure to each pregnancy complication, adjusting for factors like income, education, difference in birth weight, and smoking during pregnancy.
The study found that participants whose mothers had high blood pressure during pregnancy had higher body mass index, higher diastolic blood pressure, higher blood sugar levels, and thicker artery walls. While the difference in artery wall thickness may seem small, it corresponds to roughly three to five years of additional vascular aging, which raises the risk of future heart disease. Other pregnancy complications, such as gestational diabetes and preterm birth, also showed some long-term effects on cardiovascular health.
The study's findings suggest that improving health before and during pregnancy could help reduce heart disease risk in the next generation. According to Dr. Nilay Shah, the study's senior author, promoting health from an early age, such as exercising regularly, eating healthfully, never smoking, and getting enough sleep, is not just meant for an individual, but may also help future generations be healthier. Shah emphasizes that risk is not destiny and that most heart disease is preventable.
The study's results have significant implications for public health, particularly given the rising rates of pregnancy complications in the U.S. The researchers hope that their findings will encourage expectant mothers to prioritize their health and well-being, not just for their own sake, but also for the sake of their children's future health. By taking steps to prevent pregnancy complications and promote healthy behaviors, mothers can help give their children the best possible start in life and reduce their risk of developing heart disease later on.
The study's authors also note that the findings highlight the importance of considering the intergenerational transmission of cardiovascular risk. This means that healthcare providers should take a family-centered approach to preventing heart disease, considering not just the individual's health, but also the health of their parents and grandparents. By doing so, healthcare providers can help identify individuals who may be at higher risk of developing heart disease and provide them with targeted interventions to reduce their risk.
Overall, the study's findings suggest that heart disease risk may start in the womb, and that pregnancy complications can have a lasting impact on cardiovascular health. By prioritizing health and well-being during pregnancy and promoting healthy behaviors, mothers can help give their children the best possible start in life and reduce their risk of developing heart disease later on.
