Stress and the Asthmatic Baby
August 21st, 2008
According to researchers from Harvard Medical School, women who are stressed during pregnancy may cause their children to be more sensitive to allergen exposure when born. This stress may even influence a babyâs developing immune system and possibly develop a future risk of asthma.
âThis 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 childrenâs developing immune systems, even during pregnancy,â says Dr. Rosalind J. Wright, assistant professor of medicine at Brigham & Womenâs Hospital and Harvard Medical School.
The researchers analyzed levels of maternal stress and a motherâs exposure to dust mite allergen in the home while pregnant, examining how a childâs immune response at birth was altered. The result was clear regardless of race, class, education or smoking history: Stress magnified the effect of dust exposure on a childâs immune system.
âThis further supports the notion that stress can be thought of as a social pollutant that, when âbreathedâ into the body, may influence the bodyâs immune response similar to the effects of physical pollutants, like allergens, thus adding to their effects,â Wright says. âMelanie Wanzek
