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

Objective: To explore the effect of particles matters in the ambient air pollution on the hospital emergency treatment for respiratory diseases in Beijing. Methods: The data of the daily hospital emergency treatment for respiratory diseases fromthe PLA 305 Hospital and the clinic of eighth military cadres department of the West Third Ring general staff department, and the data of air and meteorological conditions from Beijing Municipal Environmental Monitoring Center were collected. The case-crossover design was used to analyse the data. Results: In the control of temperature and relative humidity, the results from unidirectional retrospective 1:1 matched case-crossover analysis showed that the fine particulates pollution of lag 0 days affected chronic bronchitis, asthma, chronic obstructive pulmonary disease, the OR values of the hospital emergency room visits for those diseases were 1.032, 1.033,1.035 with each increased 10 ug/m3 increment of particulate matters respectively. Conclusion: The elevated level of fine particulates pollution in atmospheric concentration can increase the hospital emergency treatment for the respiratory disease associated with chronic bronchitis, asthma, and chronic obstructive pulmonary disease in Beijing.
