Analysis And Strtegy Of Prevention And Treatment On Risk Factors Of Asthma In Children Aged0～14Years Old In Qingdao City

Objective The aim of this study was to investigate epidemiology, distribution feature and the major risk factors of asthma in children aged0～14years old in Qingdao city, and to provide scientific basis for making the prevention and control strategy of children asthma. Thus to decrease the morbidity rate of children asthma and improve the survival quality of asthma children.Methods A cluster sampling method was used for study. We randomly extracted Laoshan district for the survey,and chose the schools, nursery schools, street agencies for investigation cluster.10800children aged0～14years old in Laoshan districts of Qingdao city were investigated. A hospital-based case-control study was used to analyze the372children with asthma and the same number control children. Applying univariate and multivariate unconditional logistic regression to analyze the risk factors of children asthma.Results10800children aged0～14years old were surveyed. Of all these children,10082children were actually investigated, accounting for93.4%. Asthma (including infants)was found in315children, cough variant asthma38cases, suspected asthma19cases. The morbidity rate was3.69%, with male4.60%and female2.74%. The morbidity rate in male was higher than in female (X2=24.53, P<0.01).The attack seasons were mostly in fall winter and during seasonal variation. The rate of early accurate diagnosis and inhalation therapy was still low. The result of univariate Logistic regression analysis showed that there were17significant factors for children asthma, including premature birth, cesarean section, breastfeeding, et al. With multivariate Logistic regression analysis,13factors were entered the main effect model.12risk factors included premature birth, cesarean section, mildew spot in house, et al. Breastfeeding is the protective factor.Conclusion In our investigation, the morbidity rate of asthma in children aged0～14years old in Laoshan districts of Qingdao city was more increaseing than ten years ago. In popularization of standardized diagnosis and treatment of asthma, there was a certain difference yet contrasted with GINA project. The asthma attack was influenced by several factors, and atopic physique、genetic factors and changes in live style may be related with increased mobidity rate of children asthma. Therefore, we must control and correct the risk factors of children asthma, advocate breast feeding in infant period. There was a great significance to prevent and control children asthma.
