A new article in Annals of Allergy, Asthma and Immunology, the scientific journal of the American College of Allergy, Asthma and Immunology (ACAAI) shows a significant association between multiple prenatal and early life exposures to indoor pollutants and the degree of allergic sensitivity in 2-year-olds.
“Because most children are exposed to more than one pollutant or allergen, we examined the relationship between multiple exposures and allergic sensitizations at 2 years of age,” says Mallory Gallant, MSc, lead author of the study. “We examined exposure to dogs, cats, air fresheners, candles, mold, environmental tobacco smoke (ETS) and carpet, all of which have been associated with childhood allergies. Of the exposures we measured, prenatal exposure to candles, 6-month exposure to cats and 2-year exposure to ETS significantly increased the chance of a positive skin prick test (SPT) at 2 years of age.”
108 mother-child pairs were followed from birth to 2 years of age. Exposure to air fresheners, candles, mold, cats, dogs, carpet and environmental tobacco smoke (ETS) during the prenatal, 6-month, 1-year, and 2-year timepoints were obtained. A SPT was performed on both the mother and the 2-year-old child to measure allergic sensitivity. Allergic sensitization means that a person has had (or may have had given the possibilities for false positives) an allergic type immune response to a substance. But it does not necessarily mean that the substance causes them problems.
