Background: The clinical definition of allergic rhinitis (AR) is difficult to use in epidemiological settings of large populations where it is impossible to obtain the laboratory evidence of each immune response. However, the standardization of the definition of AR in epidemiological studies is of crucial importance. This study was designed to estimate the prevalence of AR in an adult general population with respect to seven distinct geographical regions in Turkey.
