Rationale: Current evidence on the relationship between long-term exposure to air pollution
and new onset of chronic lung disease is inconclusive. Objectives: To examine associations …

Rationale: Individuals with asthma–chronic obstructive pulmonary disease (COPD) overlap
syndrome (ACOS), have more rapid decline in lung function, more frequent exacerbations …

Rationale: Short-term exposure to air pollution has been associated with exacerbation of
chronic obstructive pulmonary disease (COPD), whereas the role of long-term exposures on …

Background: It is well known that air pollution causes respiratory morbidity and mortality by
inducing airway inflammation. However, whether long-term exposure to air pollution is …

Rationale: Limited prior data suggest an association between traffic-related air pollution and
incident asthma in adults. No published studies assess the effect of long-term exposures to …

Background Air pollution has been suggested as a risk factor for chronic obstructive
pulmonary disease (COPD), but evidence is sparse and inconsistent. Objectives We …

Rationale: Short-term exposure to air pollution has been associated with asthma
exacerbation and increased healthcare use caused by asthma, but its effect on asthma …

Objectives The role of outdoor air pollution in the incidence of chronic obstructive pulmonary
disease (COPD) remains unclear. We investigated this question using a large, nationally …

Background Exposure to environmental air pollutants exacerbates respiratory illness, but
prospective studies of disease incidence are uncommon. Further, attempts to estimate …

Rationale: Exacerbations are key events in chronic obstructive pulmonary disease (COPD),
affecting lung function decline and quality of life. The effect of exposure to different air …
