Are Baby Girls Miscarriage-Proof? Photo: Justine Cooper
We reported on a study a few months ago that found stressed women gave birth to more baby girls than boys. Now, a new study helps back up the theory that a stressful early pregnancy will raise the chances of a woman giving birth to a girl and of having a premature delivery, according to U.S. News. In a study published in a recent issue of Human Reproduction, researchers investigated how stress from a major life experience -- in this case, the 2005 earthquake in Chile -- affected childbirth. Birth certificates of Chilean babies born between 2004 and 2006 were analyzed. The investigations showed that women who were in their third month of pregnancy during the earthquake had a higher ratio of girls than boys -- and researchers believe it’s because there may have been more miscarriages for women who were expecting boys.
Researchers say that normally there are more male live births than female live births, but in this instance, there was a 5.8 percent decline in the ratio. It was also found that women who were in their second or third month of pregnancy at the time of the earthquake were more likely to have premature babies and shorter pregnancies compared to women in other regions not affected by the earthquake.
What exactly could girls be more likely to thrive? Well, prior studies have shown that baby boys tend to grow bigger in the womb and need more resources from mom, which can explain the higher rate of miscarriage if mom is severely stressed. Baby girls, on the other hand, are more capable of adapting to a changing environment in utero.
Do you think baby girls are stronger might be than baby boys? Do you agree with this study?
