Asthma is the most common chronic childhood illness in North America. Although prevalence estimates derived from cross-sectional survey data are useful, they are less informative than estimates calculated from population-based longitudinal surveillance.
This report presents Canada's first longitudinal surveillance program implemented to examine the burden of asthma on Ontario's children and on the provincial health care system.
