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。
Objective: To investigate the effects of airborne fine particulate pollutants on the emergency of respiratory diseases in Beijing. Methods: From March 2013 to March 2014, the clinical emergency data of the 305th Hospital of People’s Liberation Army (PLA) and the Third Military Medical Cadrery of the West Third Ring Road in Beijing’s No. 8 dry-rest clinics were collected. The airborne particulate pollutants and meteorological data of Beijing Municipal Environmental Monitoring Center Conditional data, application of case cross design research methods for data analysis. Results: After controlling the effects of air temperature and relative humidity, the cross-analysis of one-way retrospective 1: 1 paired case showed that the OR value of fine particulate matter with 0 hysteresis on the emergency of chronic bronchitis, asthma and chronic obstructive pulmonary disease was the highest, When the daily average concentration of fine particles was increased by 10 μg / m3, the corresponding OR values were 1.032, 1.033 and 1.035, respectively. CONCLUSIONS: Elevated concentrations of airborne particulate matter in the study area can lead to an increased emergency of respiratory diseases associated with chronic bronchitis, asthma, and COPD.
