Study: Effects of air pollution and exposure to violence in the cause of asthma

In the August 2007 issues of the journal, Environmental Health Perspectives, researchers examined the role of exposure to violence, as a chronic stressor, in altering susceptibility to traffic-related air pollution in the cause of asthma. The researchers developed models to retrospectively estimate residential exposures to traffic-related pollution for a cohort of 413 children in East Boston and merged these estimates with questionnaire data on lifetime exposure to violence in order to examine the effects of both on the cause of childhood asthma. The authors concluded that there was an association between traffic-related air pollution and asthma solely among urban children exposed to violence. Larger studies are needed to investigate other possible interactions among risk factors for asthma and also to study the effects of other pollutants. To view the full article, visit //
