Women suffering from a heart disease are more likely to deliver baby girls, claimed a new study presented at the World Congress of Cardiology. More than three-fifths of pregnant women diagnosed with heart disease delivered girls. This research was conducted by researchers from the Tabriz University in Tabriz, Iran.
According to Dr. A. Alizadehasl from the Tabriz University, this finding should lead to more research in this area. Out of the 200 women studied, the heart diseases ranged from valvular disease to congenital heart disease. These women delivered 216 babies, three-fourths of which were female.
This is a very interesting observation in the context of the fact that male chromosome are considered the only factor responsible for determining the sex of the progeny. But this study has opened a new field of investigation as it suggests that the status of health of the mother might have a relationship with the health of the mother. With an increase in the number of heart disease around the world, there is a lot of scope for research on this new aspect brought to light by the study.
The proportion of boys compared to girls born in any country should be more or less the same, but the boy-to-girl ratio in a given country varies based on the prevailing practices of sex selection and preference. In Iran, about 105 boys are born for every 100 girls, according to the Central Intelligence Agency. In the heart disease study, 32 boys were born for every 100 girls.
A study has suggested women that women are more likely to have girls during a famine. The researchers who said this speculated that it may be because during a famine, male sperm that carries Y chromosome is less inclined to fertilise eggs. It could also mean that during famine, foetuses with Y chromosomes are more likely to result in miscarriage.
Cardiovascular diseases (CVD), which includes heart disease and stroke, is the biggest killer of women in the world claiming 8.6 million deaths every year. Women in low and middle income countries develop CVD and die from it than comparable women in industrialised nations.
However, women are not inclined to see CVD as the biggest threat to their health as they feel cancer to be more threatening than CVD. If they realise this should take heart from the fact that steps can be taken to protect their hearts. The first and most important steps include stopping smoking, having more of physical exercise, maintaining healthy weight, and making sure that the food they eat is healthy and balanced.
