【摘要】 目的探讨儿童反复呼吸道感染(RRTI)的发病率及其影响因素。方法参照文献方法设计调查问卷,以临床流行病学调查研究结果统计RRTI的发病率;采集出生抚育、生长发育和既往病史等基本信息,以单因素和多因素分析,归纳RRTI发病的影响因素。结果对上海地区517例适龄儿童的临床调查显示,儿童RRTI的社区患病率为8.9%,且年龄越小患病率越高,但性别间无显著差异。年龄、剖宫产儿、过期产儿、始行月龄、过敏史、哮喘/咳嗽变异性哮喘史、湿疹/荨麻疹史、厌食及营养不良史、胃食管反流表现等均为RRTI发病的影响因素。结论必须重视上海地区儿童RRTI的预防和诊治,基于大样本临床流行病学调查的各影响因素可供临床诊断、治疗及其预防参考。更多还原
