上海城区室内环境因素对4～17岁儿童青少年呼吸道症状的影响研究

目的探讨室内环境因素对儿童与青少年呼吸道症状的影响。方法采用横断面研究方法,于2007年对上海城区16所中小学和幼儿园的4～17岁6551名儿童青少年的呼吸道症状的发生情况、家庭及教室环境因素进行调查,同时调查社会经济状况和遗传等潜在混杂因素。分析室内环境危险因素对儿童与青少年呼吸道症状的影响。结果调整了潜在混杂因素后,父、母室内吸烟、居室附近50m之内车辆繁忙的街道是持续咳嗽、喘息和喘息样症状的危险因素;父室内吸烟是咳痰的危险因素;室内霉斑、2年内居室装修是持续咳嗽、喘息的危险因素;饲养皮毛动物、1年内购置新家俱、室内潮湿是咳嗽、咳痰的危险因素;常使用空气清洁化学品、每天使用燃气炉大于45min可能分别对咳痰和喘息有影响。结论父母室内吸烟是增加4～17岁儿童青少年呼吸道症状风险重要危险因素。饲养宠物、室内霉斑、新近装修和购置新家俱、室内长时间使用燃气炉可能增加呼吸道症状的风险。
