We observed a decrease in the prevalence of hay fever in children and increase in the older age groups. A clear urban-rural association observed over years may be explained by environmental factors. Deviations from this general regional pattern in children of the age group 0-14 years may be explained by differing age-specific risk factors of hay fever.
