Background: Air pollution is a known trigger for exacerbations among individuals with
asthma, but its role in the development of new-onset asthma is unclear. We compared the …

Background: Although it is well established that air pollutants can exacerbate asthma, the
link with new asthma onset in children is less clear. Objective: We assessed the association …

Background: It is well established that short-term exposure to ambient air pollutants can
exacerbate asthma, the role of early life or long-term exposure is less clear. We assessed …

Whether improvement in air quality due to reduced industrial emissions has resulted in …

Background There is increasing recognition of the importance of early environmental
exposures in the development of childhood asthma. Outdoor air pollution is a recognized …

Background Air pollution can have adverse health effects on asthma sufferers, but the effects
vary with geographic, environmental and population characteristics. There has been no long …

Within-city variation in air pollution has been associated with childhood asthma
