Stress during pregnancy is harmful for baby
May 20, 2008
CHICAGO – In a recent research done in US, It is established that females whoa re exposed to stress during pregnancy may give birth to a child who has low immunity and might suffer from diseases like asthma and allergies.
The studies presented at a meeting of the American Thoracic Society in Toronto, propose a mother’s stress during pregnancy may have lasting penalty for her child.
“This research adds to a growing body of evidence that links maternal stress such as that precipitated by financial problems or relationship issues to changes in children’s developing immune systems, even during pregnancy,” Dr. Rosalind Wright of Harvard Medical School in Boston said.
Wright and colleagues established mothers who were the most upset during pregnancy were most likely to give birth to infants with higher levels of immunoglobulin E or IgE — an immune system compound even though their mothers had only gentle contact to allergens during pregnancy.
Studies in animals have found that a mother’s stress amplify the effects of allergen exposure on the immune system of the developing offspring. The Harvard team set out to see if they could find the same in humans.
They deliberate levels of IgE from the umbilical cord blood of 387 newborns in Boston.
Babies whose mothers were the most stressed out — but who had low contact to dust mites in the home still had high levels of IgE in their cord blood, a finding that proposes that stress augmented the immune response to dust exposure.
This was true irrespective of the mother’s race, class, learning or smoking history.
