The Prevalence And Risk Factors Of Asthma In Urumqi, Xinjiang Uygur Autonomous Region

Objective: To investigate the prevalence and its risk factors of asthma of children inUrumqi,Xinjiang Uygur Autonomous Region. Methods:6points were selected by clustersampling with a total number of12000children respect.But only11929samples wereinvestigated. Results: There were132patients with asthma and the prevalence is1.11%.The prevalence of baby, preschoolers and school age children was0.42%,1.00%and1.36,respectively. With the age raising, the incidence of asthma was raise up(χ2=13.312, P＜0.001). With the age raising, the incidence of asthma was raise up (χ2=13.642, P＜0.001).The incidence male and female was1.46%and0.75%, respectively. The single factorunconditional Logistic regression analysis showed that the prccess is connected withage(OR=1.703,95%CI:1.308～2.216), gender(OR=0.516,95%CI:0.358～0.743), whetherthey have gasping(OR=208.56,95%CI:122.45～355.24), have a cough more than amonth(OR=10.908,95%CI:7.529～15.804), more than six times upper respiratory tractinfection in one year(OR=10.33,95%CI:7.29～14.64), history of allergy (OR=11.02,95%CI:6.69～18.16), family history(OR=5.84,95%CI=4.13～8.26).The multiple factorunconditional Logistic regression analysis showed that age(OR=1.703,95%CI:1.308～2.216), whether they have gasping(OR=208.56，95%CI:122.45～355.24), have a coughmore than a month(OR=10.908,95%CI:7.529～15.804), more than six times upperrespiratory tract infection in one year(OR=10.33,95%CI:7.29～14.64), history ofallergy(OR=11.02,95%CI:6.69～18.16) are the risk factors in asthma. Conclusion: Theresults of this study showed that the incidence of asthma and its correlation factors. Theprevalence of asthma in baby is lower, but in the school age children is high.theprevalence is difference in male and female.
