Survey On The Prevalence Rate And Risk Fackors Of Childhood Asthma Aged0to14in Chongqing City

PART ONE:SURVEY ON THE PREVALENCE RATE OF CHILDHOOD ASTHMA AGED0TO14IN CHONGQING CITYObjective:to investigate prevalence rate and Clinical features of childhood asthma aged0to14in Chongqing city, so as to provide a scientific basis for prevention and treatment of bronchial asthma in children.Methods:(1) to extract12000children aged0-14by cluster random sampling in chongqing city;(2)by filling out the children’s asthma and allergic diseases screening table to survey the12000children aged0-14,and to filter out suspicious asthmatic children;(3)by history taking, physical examination, pulmonary function tests, food allergens check to diagnosis the suspicious asthmatic children,and Children with asthma fill in the questionnaire of children with asthma.Results:(1) asthma prevalence is4.46percent in Children aged0-14, prevalence rate was higher for children0-7years; the asthma prevalence was4.93%in boy,3.93%of girls with asthma prevalence,the difference was statistically significant (P<0.05);(2) The upper respiratory tract infections were the main reasons to induce asthma;(3)44.49%of children with asthma combined with allergic rhinitis;(4) In the treatment to acute episode of asthma, glucocorticoid in whole body was used in36.56%patients,02agonists was used in62.85%patients, theophylline was used in31.15%patients, up to83.63%patients used antibiotics; in the long-term prevention and treatment process of asthma, only48.31%patients used inhaled glucocorticoid, anti-leukotriene drugs was used in24.80%patients,allergy was used in26.64%patients, the utilization rate of desensitization therapy, immunomodulatory agents, traditional Chinese medicine as well as peak flow meter were2.57%,8.30%,27.89%,6.56%in patients.Conclusion:(1)The prevalence rate of asthma in children in Chongqing was increase up39.82%Compared with2000;(2) The upper respiratory tract infections were the main reasons to induce asthma;(3) The treatment programs of asthma was sill not standardized. PART TWO:CASE-CONTROL STUDY ON RISK FACTORS FOR ASTHMA IN CHILDREN IN CHONGQING CITYObjective:To analyze the risk factors associated with childhood asthma in children by Case-control study;Methods:to analyses risk factors for asthma in270pairs of children by logistic regression analysis.Results:The result of univariate Logistic regression analysis showed that there were many related factors for children asthma. including disease history of parents in respiratory system, Allergic rhinitis, food allergies, pregnancy conditions, production situation, add a protein supplement, house decoration, wall materials, furniture materials, the bedroom door and window materials, indoor ventilation, indoor mildew, household smoking.With multivariate Logistic regression analysis,6factors were entered the model,4risk factors including A history of relatives with asthma(The coefficients was2.4231), second-degree relative history of asthma(The coefficients was1.6544), allergic rhinitis(The coefficients was2.5507), premature birth (The coefficients was1.6378)and2protective factor of Wall materials using wallpaper and doors (The coefficients was-2.1331)and windows materials using steel in bedroom(The coefficients was-1.4301).Conclusion:(1) family history of asthma, allergic rhinitis and premature delivery were risk factor for asthma in children;(2) choose environmentally friendly materials and maintain ventilation may reduce prevalence of childhood asthma in Chongqing Municipality when carrying out interior decoration;...
