This study was designed to examine differences in the respiratory health status of preadolescent school children, aged 7-11 years, who resided in 10 rural Canadian communities in areas of moderate and low exposure to regional sulfate and ozone pollution.
Five of the communities were located in central Saskatchewan, a low-exposure region, and five were located in southwestem Ontario, an area with moderately elevated exposures resulting from long-range atmospheric transport of polluted air masses.
In this cross-sectional study, the child's respiratory symptoms and illness history were evaluated using a parent-completed questionnaire, administered in September 1985.
