A large cross-sectional study provided an opportunity to estimate the prevalence of childhood asthma in several regions across Canada.
In 1988, approximately 18 000 questionnaires were distributed to the families of 5-8 year old children in 30 communities from the following six regions across Canada : the interior of British Columbia, southeastern Saskatchewan, southwestern Ontario, the central region of Ontario, southern Quebec, and the Maritimes (Nova Scotia and Prince Edward Island).
These communities were free of point-source air pollutants and selected to represent a range of ambient sulphate concentrations.
