The number of times a mother gives birth can be linked to heart disease, research says.
A recent study from the University of Texas Southwestern Medical Center suggests that women with four or more children have higher chances of developing heart disease. The researchers, led by Monika Sanghavi, speculated that the number of pregnancies can be associated with early signs of heart illness.
Sanghavi and her team carried out the study by selecting 1,644 women with an average age of 45. Nearly 60 percent of the participants were African-Americans.
To obtain substantial information, all participants indicated the number of live births they had in the past. They also underwent relevant imaging tests – tomography imaging and magnetic resonance imaging – to gather evidence of subclinical atherosclerosis [ath-uh-roh-skluh-ROH-sis, ath-] in their hearts and artery walls.
Results of the study showed that women who gave birth to four or more children have higher risks of cardiovascular disease compared to women with two to three live births.
However, the researchers were surprised to know that the women with zero to one live birth also showed signs of subclinical atherosclerosis. The team assumed that some of these participants have an underlying medical condition that prevented them from having successful live births. This particular medical condition can also cause heart disease.
Sanghavi said that this study is intended to look into possible factors contributing to heart disease and not as a basis for the number of children a woman can have.
