Background: Evidence linking prenatal exposure to outdoor air
pollution with allergic disease in early childhood is scare, and
the role of components of air pollution and exposure timing
Objectives: We investigated the association between maternal exposure to air pollution during pregnancy and the prevalence of allergic diseases in preschool children.
Methods: We conducted a prospective cohort study of 2598 children aged 3–6 years in Changsha, China. The prevalence of allergic diseases was assessed by a standardized health questionnaire administered by the parents. Individual exposures to nitrogen dioxide (NO2), sulfur dioxide (SO2) and particulate matter with an aerodynamic diameter ≤ 10μm (PM10) during pregnancy and different trimesters were estimated by an inverse distance weighted (IDW) method based on concentrations measured at monitoring stations. Association between childhood allergic diseases and maternal exposure to air pollution was examined by logistic regression models in terms of odds ratio (OR) and 95% confidence interval (CI) for an interquartile range (IQR) increase in exposure.
Conclusion: Our findings indicates that childhood allergy is associated with maternal exposure to traffic-related air pollutant during pregnancy, which support the hypothesis that fetal origins of childhood allergy.
