儿童社区获得性肺炎支原体肺炎危险因素logistic回归分析

摘要

[目的]探索儿童社区获得性肺炎支原体肺炎的危险因素.[方法]采用非条件logistic回归分析对38例支原体肺炎的儿童和同期住院的30例非肺炎支原体感染肺炎的对照病例的16个危险因素进行比较分析.[结果]多因素非条件Logistic回归分析结果表明:住院前联合用抗生素种类(OR=2.525,95%CI为1.352～4.717)、肺实变(OR=5.489,95%CI为1.445～20.854)、气喘(OR=3.438,95%CI为1.012～11.677)以及既往住院次数(本次起病3月内)(OR=1.768,95%CI为0.906～3.451)是儿童社区获得性肺炎支原体肺炎的独立危险因素.[结论]针对上述危险因素要注意合理使用抗生素,避免反复感染,多次住院,并要积极重视喘息,肺实变等临床表现,争取早期诊断.%[Objective] To explore the risk factors of infection by Mycop1asma Pneumoniae in children withcommunity acquired pneumonia(CΛP). [Methods] Non conditional logistic regression analysis was used to analyze 16 risk factors of 38 children with infection by Mycoplasma Pneumonia and 30 control cases without infection by Mycoplasma Pneumonia. [Results] Multifactor non conditional logistic regression analysis showed that the combined application of antibiotic(OR=2.525, 95％CI: 1.352～4.717), lung consolidation(OR=5.489,95％CI: 1.445～20.854), asthma(OR=3.438, 95％CI: 1.012～11.677) and inpatient history within 3months after the onset(OR=1.768, 95％CI: 0.906～3.451) were the independent risk factors of infection by Mycoplasma Pneumoniae. [Conclusion] Infection of Mycoplasma Pneumoniae is related to many factors such as the combined application of antibiotics, lung consolidation, asthma and inpatient history.
