year of age,maternal alcohol consumption during pregnancy,pets at home,flowers/plants at home,smoking in the home,cooking fuel,heating method,kitchen exhaust method,and plush toys in the home(P value All <0.05).5.The results of logistic regression analysis indicated that obesity(OR=1.37,95%CI:1.13~1.66),living in the city(OR=1.39,95%CI: 1.16~1.68),father’s allergic rhinitis history(OR=1.86,95 %CI: 1.57~2.20),maternal allergic rhinitis history(OR=1.57,95%CI:1.35~1.83),asthma(OR=6.17,95%CI: 4.48~8.49),eczema(OR=2.05,95%CI: 1.71~2.46),allergic to drugs(OR=1.87,95%CI: 1.46~2.39),mode of delivery was cesarean section(OR=1.23,95%CI: 1.07~1.42),history of surgery(OR=1.54,95%CI: 1.14~2.09),suffered from neonatal jaundice(OR=1.24,95%CI: 1.05~1.46),used antibiotics within 1 year of age(OR=1.33,95%CI: 1.13~1.56),raised at home Pets(OR=1.33,95%CI: 1.10~1.62)and someone smoking at home(OR=1.26,95%CI: 1.10~1.45)were independent risk factors for allergic rhinitis in children,and the

gas(OR=0.75,95%CI:0.59~0.95),and the presence of plush toys in the home(OR=0.83,95%CI: 0.70~0.98)were the protective factors for allergic rhinitis in children.Conclusion The reported incidence of
