This news is based on the following article: Rancière F, Bougas N, Viola M, Momas I. Early exposure to traffic-related air pollution, respiratory symptoms at 4 years of age, and potential effect modification by parental allergy, stressful family events, and sex: a prospective follow-up study of the PARIS birth cohort. Environ Health Perspect 2017 ; 125 : 737-45. doi : 10.1289/EHP239
This analysis of the PARIS birth cohort (Pollution and Asthma Risk: an Infant Study) supports the hypothesis that children are unequal regarding the adverse respiratory health effects of traffic-related pollution. Male sex, parental history of allergy and a stressful family experience appear to increase the risk of asthma caused by exposure to pollution in the first year of life and of the persistence of asthma and rhinitis symptoms up to the age of 4.
