儿童支气管哮喘发病的危险因素分析

目的：探讨儿童支气管哮喘发病的危险因素。方法选取就诊于我院的儿童支气管患儿176例纳入哮喘组，同时选取同期正常儿童176例纳入正常组。首先采用SPSS17.0作单因素分析可能引起儿童支气管哮喘的发病因素17项，筛选出P＜0.05的单因素作Logistic回归模型的自变量，作多因素分析，得出影响儿童支气管哮喘的高危因素。结果经单因素分析结果显示，影响儿童支气管哮喘的单因素共有10项，且P＜0.05，与正常组对比具有统计学意义。Logistic多因素回归分析结果显示，影响儿童支气管哮喘的高危因素为呼吸道感染、家族哮喘史、未补充鱼肝油、家人吸烟，且母乳喂养是哮喘的保护因素。结论积极预防儿童哮喘的高危因素，提高保护意识，对于预防和控制儿童哮喘具有重要意义。

Analysis of risk factors of childhood bronchial asthma

Objective To investigate and analyze the risk factors of childhood bronchial asthma. Methods 176 children with bronchial asthma treated in our hospital were selected as the asthma group and 176 normal children in the corresponding period were selected as the normal group in the same time. First, SPSS17.0 was used to conduct univariate analysis on 17 pathogenic factors of childhood bronchial asthma and the screened out single factors with P 〈 0.05 served as the independent variables of Logistic regression model for multivariate analysis. Then the high risk factors of childhood bronchial asthma were obtained. Results Univariate analysis showed that there were 10 single factors influencing childhood bronchial asthma, with statistically significant differences to the normal group （P〈0.05）. Logistic multivariate regression analysis showed that the high risk factors of childhood bronchial asthma were respiratory tract infection, family history of asthma,non-supplement of cod liver oil and family smoking and the protective factor of asthma was breastfeeding. Conclusion Preventing high risk factors of childhood bronchial asthma actively and increasing protective awareness are of important significance to the prevention and control of childhood bronchial asthma.
