To investigate trends in the prevalence of allergic disease over a 9-year period.

Methods

Annual populations for each sub-region were obtained and used to calculate the standardized prevalence. To compare prevalence within the study period, data was standardized spatially and temporally.

In addition, a geographic information system (GIS) was used to visualize prevalence for in
