Stress in pregnant women Should be avoided, ESPECIALLY for Those WHO want a baby boy. A recent research shows That the stress in early pregnancy can Reduced-one's chances to get a boy child and increase of the risk of premature birth.
This finding was associated with the investigation of how the massive earthquake in Chile in 2005 affects most pregnant women thereby triggering the emergence of stress, the Researchers said.
Researchers analyzed the birth certificates of all babies born in Chile in the years 2004-2006. Each year there are about 200,000 known babies born. Birth records Provide information about the mother and baby, including how close the mother to the epicenter.
According to a report published on December 8, 2011 issue of the journal Human Reproduction, the study found That exposure to the earthquake During the third month of pregnancy reduces birth ratio of boys.
"In general, more babies are born with male sex than women. The ratio of the between men and women around 51:49. In other words, of every 100 births, there are 51 boys. But with the incident (earthquake) We note That there is a Decrease of 5.8 percent related to the proportion of male births (45 per 100 births). The change is quite significant, "said Dr. Karine Kleinhaus, assistant professor of psychiatry, obstetrics & gynecology, and environmental medicine from New York University.
Kleinhaus rate, this finding was associated with previous research, the which has found That male fetuses growing niche to grow larger than females and need more food intake of expectant mothers, and therefore also more Likely to experience a miscarriage at the time of stress.
He also added That the male fetus may not be as strong as female fetuses and growing niche to be less capable of adapting to environmental changes in the uterus Pls a mother is stressed.
In Addition, Researchers also compared the condition of pregnant women living in areas with Those WHO did not Quake.When compared with WHO's pregnant women are not affected by the earthquake, pregnancies of women exposed to the earthquake in the second month of pregnancy on average 1.3 days shorter, and Their pregnancies are affected by the earthquake in the third month of pregnancy on average 2 daysshorter.Researchers confirmed the event so That exposure to the earthquake did not have a significant effect on a person's risk of having a premature baby boy.
