Abstract:
Objective:To investigate prevalent aeroallergens in ChongQing and their sensitization risk factors in children with allergic diseases,especially asthma.Methods:Skin prick tests with 13 standardized aeroallergens and questionnaires were used.A total of 298 patients,aged between 4~15 years and were diagnosed with allergic asthma and or allergic rhinitis,were investigated.Results:The total positive rate of allergen was 84.9%(253/298).The prevalence of aeroallergens were following:the first was house dust mite,cockroach followed,the third one was cat dander;the positive family history of asthma was 69.6%(116/230),asthma and rhinitis accounted for 67.2%(78/116)。Multivariate logistic regression analyses revealed that house dust mite was an independent risk factors for asthma(odds ratio Value(OR):2.602,95%CI:1.672～7.488),air conditioning had strong relationship with it(OR:1.659,95%CI:1.139～5.942).Conclusion:House dust mite is the major allergen of allergic diseases,especially asthma in ChongQing.Air conditioning is one of important risk factors for house dust mite sensitization.
