Women who gave birth have a greater chance of developing cardiovascular disease and stroke than those who are childless, a new study said.
Previous studies have shown that women usually show changes in vascular properties, blood volume and heart rate during pregnancy. However, the effect of pregnancy on a subsequent heart disease is discussed.
In the new study, a team from Huazhong University of Science and Technology in China, examined 10 studies. It employs nearly three million women worldwide, with over 150,000 diagnosed with heart disease or strokes over the next six to 52 years.
The findings, published in the European Society of Cardiology, show that birth has a 14% higher risk of heart disease and stroke.
There is also a significant link between the number of pregnancies and the risk of cardiovascular disease.
Women have had a four percent increase in the incidence of cardiovascular disease each time they give birth regardless of weight, diabetes, high blood pressure, smoking and incomes.
Each delivery increases the risk of coronary heart disease by five percent and strokes by three percent, the researchers say.
According to Wang Dongming, a leading researcher at the university, pregnancy can cause inflammation in the body and accumulation of fat around the abdomen, blood and arteries.
These changes can have a constant effect on the cardiovascular system, which leads to an increased risk of heart disease and stroke.
However, he said that women can do a lot to prevent cardiovascular disease.
Scientists have suggested giving up smoking, doing more exercise, a healthy diet, and controlling weight to improve future health.
