幼儿反复下呼吸道感染危险因素分析

Risk factors for recurrent lower respiratory tract infections in infants

目的分析幼儿反复下呼吸道感染(RLRTI)的危险因素。方法选择新疆医科大学第一附属医院儿科收治的123例反复下呼吸道感染幼儿为RLRTI组,取同期117例非反复呼吸道感染幼儿作为对照组,对可能影响反复下呼吸道感染的因素进行单因素分析和Logistic回归分析。结果单因素分析显示IgA、IgG、营养不良、过敏体质、合并基础疾病及非正规治疗6个因素与幼儿反复下呼吸道感染相关(P<0.05);Logistic回归分析显示IgA、营养不良、过敏体质及合并基础疾病是幼儿反复下呼吸道感染的独立危险因素(P<0.05)。结论提高幼儿免疫力、合理膳食加强营养、减少与过敏物质接触并及早治疗基础疾病可减少幼儿反复下呼吸道感染的发生。

Objective To analyze the risk factors of recurrent lower respiratory tract infections in infants. Methods 123 infants with recurrent lower respiratory tract infections were analyzed retrospectively.117 patients with other diseases of respiratory tract infections were compared.Independent variables were ana-lyzed by univariate analysis and logistic regression to screen out the risk factors.Results Single factor a-nalysis was conducted for 6 risk factors.IgA,IgG,malnutrition,allergy,with basic diseases and Informal treatment were considered statistically significant （P 〈0.05）.Logistic regression model analysis showed that IgA,malnutrition,allergy,and with basic diseases were the independent risk factors of recurrent lower respiratory tract infections （P 〈0.05）.Conclusion Improving immunity in infants,suppling nutri-tious food,reducing the chance to contact allergies,and curing the basic diseases can decrease the incidence of recurrent lower respiratory tract infections.
