Abstract:
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
remains unclear.
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.
