The prenatal and postnatal effects of air pollution on asthma in children with atopic dermatitis

Objectives Air pollution is strongly associated with asthma, but has not been determined to induce new‐onset asthma development in children with atopic dermatitis (AD). Working Hypothesis To assess whether prenatal/postnatal exposure to air pollutants triggers new‐onset asthma development in children with AD. Study Design Retrospective cohort study. Patient‐subject Selection Data of patients 3% were significantly influenced by prenatal exposure to PM2.5, especially SO2, NO, and NO2. Conclusions Prenatal and postnatal exposure to air pollution have an association with asthma development in AD patients.
