The difference of prevalence between female (13.57%) and male (15.44%) was insignificant statistically (Χ2=0.454, P>0.05). The difference of prevalence between the Han (15.72%) and the Hui (11.35%) insignificant statistically (Χ2=2.055, P>0.05). The prevalence of AR children aged five to nine years was 13.80%, as aged ten to fourteen years was 19.72%. There was a significante differece between two groups (Χ2=4.056, P<0.05). The most explosive outbreak month in children with allergic rhinitis was July to September.
