| 摘要： | Living near traffic has been associated with asthma and other respiratory symptoms. Most studies, however, have been conducted in areas with high background levels of ambient air pollution, making it challenging to isolate an independent effect of traffic. Additionally, most investigations have used surrogates of exposure as few have measured traffic pollutants directly as part of the study. We conducted a cross-sectional study of current asthma and other respiratory symptoms in children (n=1080) living at varying distances from high-traffic roads in the San Francisco Bay Area, a highly urbanized region characterized by good regional air quality due to coastal breezes. Health information and home environmental factors were obtained by parental questionnaire. Exposure was assessed with several measures of residential proximity to traffic calculated using geographic information systems (GIS), including traffic within a given radius and distance to major roads. We also measured traffic-related pollutants (nitrogen oxides and nitrogen dioxide) for a subset of households to determine how well traffic metrics correlated with measured traffic pollutants. / Availability Note: Product reproduced from digital image.
