Clinical characteristics and prevalence of asthma in schoolchildren diagnosed with allergic rhinitis and non- allergic rhinitis 3 years after diagnosis / 实用医学杂志

ABSTRACT

Objective To observe the clinical characteristics in schoolchildren diagnosed with allergic rhi-nitis(AR)and nonallergic rhinitis(NAR)three years ago,and to compare the prevalence of asthma and chronic cough among them and the impacts of AR and NAR on the quality of life. Methods Totally 146 AR children and 108 NAR ones diagnosed between September 2013 and March 2014 were surveyed using a questionnaire by tele-phone and all the children were not complicated with chronic cough and asthma. The statistical analysis was per-formed by a professional statistician using SPSS 12.0 statistical software. Results A total of 111 questionnaires were completed in AR group and 76 in NAR group. The prevalence of asthma was 11.7%(13/111)in AR group while 6.6%(5/76)in NAR group and there was no statistically significant difference(χ2=1.366,P=0.242). The prevalence of chronic cough was 26.1%(29/111)in AR group and 13.2%(10/76)in NAR group and there was sta-tistically significant difference(χ2=4.596,P=0.032). The score of rhinitis visual scale(VAS)and rhinoconjunc-tivitis quality of life questionnaire(RQLQ)was significant higher in AR group than that in NAR group(t = 2.570 and 2.467,P=0.012 and 0.016). Conclusions Children with NAR may also have the risk for the development of asthma as those with AR. The prevalence of chronic cough is higher in children with AR than in those with NAR. AR might bring more impacts on children′s quality of life than NAR.
