北京市大气细颗粒污染物与老年呼吸系统疾病急诊就医关系的病例交叉研究

目的:探讨北京市大气细颗粒污染物对呼吸系统疾病急诊的影响。方法:收集2013年3月-2014年3月解放军305医院以及西三环的总参军训部北京第八干休所门诊部的临床病例急诊数据、北京市环境监测中心的大气细颗粒污染物和气象条件数据资料,应用病例交叉设计研究方法进行数据分析。结果:在控制气温、相对湿度的影响后,单向回顾性1:1配对病例交叉分析结果显示,滞后0天细颗粒物污染对慢性支气管炎、哮喘、慢性阻塞性肺病急诊影响的OR值最大,细颗粒物日平均浓度每升高10μg/m3,对应的OR值分别为1.032、1.033、1.035。结论:该研究区域内大气细颗粒物污染物浓度升高可以导致呼吸系统疾病相关的慢性支气管炎、哮喘、慢性阻塞性肺病疾病的急诊增加。

Association between Particulate Matters in the Ambient air Pollution andHospital Emergency Treatment for Elderly Respiratory Diseasesin Beijing: A Case Crossover Study

Objective:To explore the effect of particles matters in the ambient air pollution on the hospital emergency treatmentfor respiratory diseases in Beijing.Methods:The data of the daily hospital emergency treatment for respiratory diseases fromthe PLA 305Hospital and the clinic of eighth military cadres department of the West Third Ring general staff department, and the data of air andmeteorological conditions fromBeijing Municipal Environmental Monitoring Center were collected. The case-crossover design was usedto analyse the data.Results:In the control of temperature and relative humidity, the results from unidirectional retrospective 1:1 matchedcase-crossover analysis showed that the fine particulates pollution of lag 0 days affected chronic bronchitis, asthma, chronic obstructivepulmonary disease, the OR values of the hospital emergency room visits for those diseases were 1.032, 1.033,1.035 with each increased10 ug/m3 increment of particulate matters respectively.Conclusion:The elevated level of fine particulates pollution in atmosphericconcentration can increase the hospital emergency treatment for the respiratory disease associated with chronic bronchitis, asthma, andchronic obstructive pulmonary disease in Beijing.
