Long-Term Exposure to Nitrogen Dioxide and Ozone and Respiratory Health in Children.

ABSTRACT: Rationale: Further evaluation of the impact of long-term exposure to the gaseous air pollutants nitrogen dioxide (NO₂) and ozone (O₃) on child lung function and of NO₂ or O₃ on eosinophilic airway inflammation is needed. Objectives: To determine whether NO₂ and O₃ are associated with lung function and fractional exhaled nitric oxide (Fe_NO) in children. Methods: We measured lung function (forced expiratory volume in 1 second [FEV₁] and forced vital capacity [FVC]) at midchildhood (mean age, 7.9 yr; n = 703), early teens (13.2 yr; n = 976), and midteens (17.6 yr; n = 624) study visits, and Fe_NO at the early and midteens study visits in Project Viva, a c
