摘要
目的探讨沙尘暴对儿童呼吸系统症状发生的影响。方法选取兰州市3所小学和敦煌市1所小学的3～5年级的1094名学生为研究对象,在2009年4月23日沙尘暴发生前1d发放调查问卷,连续跟踪调查7d,调查的主要内容为一般状况、个人情况和呼吸系统症状等。结果与沙尘暴发生前1d比较,沙尘暴发生当天儿童呼吸系统症状的发生率均不同程度地升高,其中鼻腔干燥、流涕、鼻塞、流鼻血、咽部干痒、咽痛、咳嗽、口苦、持续咳嗽、早晨咳嗽、户外咳嗽加重、咳嗽有痰及胸部憋闷症状发生率升高,差异均有统计学意义(P<0.05)。沙尘暴过境后第1～5天,儿童呼吸系统症状发生率逐渐降低。多因素Logistic回归分析结果表明,沙尘暴发生前有身体不适、支气管炎、上呼吸道感染等病史的儿童沙尘暴期间呼吸系统症状发生的危险性升高,OR值分别为1.873、2.239和1.595。结论沙尘暴对儿童造成呼吸系统的急性损伤,且高发于既往有呼吸系统病史的儿童。
Objective To explore the adverse effects of sandstorm on children＇s respiratory system.Methods During the sandstorm,students of grades 3-5 were selected in 4 primary schools of Lanzhou and Dunhuang.1 094 students were selected as the subjects in the present study.Questionnaires investigation was conducted the day before the dust storm on April 23,2009 and the followed up investigation of 7 consecutive days was done.Contents of the research included general conditions and respiratory symptoms.Results The number of children with various acute stimulated symptoms increased in various degree on the sandstorm day compared with the day before the dust storm,as for the symptoms such as nasal dryness,runny nose,rhinostegnosis,epistaxis,dryness of the throat,pharyngodynia,cough,bitter mouth,persistent cough,morning cough,serious outdoor cough,productivecough and chest depressing,the differences were significant between the two days（P〈0.05）.The incidence of children＇s respiratory symptoms decreased gradually after the accident day（1st day to 5th）.The results of multiple logistic analysis showed that the children with bronchitis and upper respiratory tract infection before sandstorm were prone to have respiratory diseases after the sandstorm,OR values separately were 1.873,2.239 and 1.595.Conclusion Dust storms can cause acute injury in the respiratory system of children,and the incidence in children with respiratory diseases history is high.
