Number of children is rising as a new factor that influences the risk for some cardiovascular illnesses (CVD) or heart disease risk, and in some societies in each parent, according to Professor Vera Regitz-Zagrosek, chairperson of the European Society of Cardiology management of CVD During Pregnancy” guidelines task force.
Her comments come as a new study released in Circulation determined that experiencing a couple of pregnancies raises a woman’s threat of having atrial fibrillation (AF) later in life. According to her, the study described a linear expansion in AF with increasing number of pregnancies. This is exciting and is considered evidence that may happen through biological and sociocultural reasons.
A study concerning 0.5 million Chinese men and women determined a statistically huge J-shaped relationship between number of kids and threat of heart disorder and stroke. The authors of the study commented that it signifies that the risk decreases with one child, then increases with two or more children. They also mentioned that in the AF study, a J-formed relationship was once not statistically significant, but this may be because it was in around 34,000 women and slightly smaller than the Chinese study.
The lead author of the study commented that the factor was that the Chinese study showed the same association for women and men. In another study, they validated the same J-shaped association between number of children and risk of diabetes in women and men.
The authors feel that socioeconomic factors are the explanation. Having one child is protecting considering the fact that father and mother have social aid in older age. But if they have a large number of kids this advantage goes away given that it increases the economic and social stress on the parents.The number of children should be viewed a new aspect that will influence the risk for some cardiovascular diseases for people and included in study databases to be additionally investigated as a health indicator.
The lead author mentioned that more research should investigate biological and socioeconomic factors to provide an explanation for the relationship between number of children and heart disease risk. According to her,
There is evidence that being pregnant leads to alterations that adjust the body’s response to further cardiovascular stressors. This will likely occur through epigenetic mechanisms. However the findings in Chinese men favour the socioeconomic rationalization.
A separate study in the journal Circulation determined that delivering a premature baby could also be related to later cardiovascular disease, regardless of other risk explanations. Researchers reviewed information from 70 182 women in the Nurses’ Health Study II and realized that women who have a premature baby earlier than 37 weeks gestation of their first birth have a 40% higher risk of later CVD compared to women who delivered at term, and those who delivered earlier than 32 weeks are at twice the danger compared to full-term deliveries.
