Chronic Obstructive Pulmonary Disease and Long-Term Exposure to Traffic-Related Air Pollution: A Cohort Study (Abstract, American Journal of Respiratory and Critical Care Medicine., Sep. 24, 2010)

Also discussed here: Air Pollution Exposure Increases Risk of Severe COPD (Science Daily, Nov. 5, 2010)

Key Quotes:

“Long term exposure to low-level air pollution may increase the risk of severe chronic obstructive pulmonary disease (COPD)”

“estimated pollution exposure by linking residential addresses to outdoor levels of NO2 and NOx levels, which were used to approximate the overall level of traffic-related pollutants since 1971. They looked at exposures over 15-, 25- and 35-year periods to assess the effect of different exposure lengths on COPD incidence”

"When we adjusted for smoking status and other confounding factors, the association remained significant, indicating that long-term pollution exposure likely is a true risk factor for developing COPD."

“effect of air pollution on COPD was strongest in people with pre-existing diabetes and asthma”

"In any case, sufficient data, including the results of this study, provide evidence that traffic-related urban air pollution contributes to the burden of COPD and that reductions in traffic emissions would be beneficial to public health."
