许多流行病学研究表明,健康和室外空气污染的电流水平之间积极的短期关联。这项研究的目的是研究空气污染和参观急症(A&E)部门在伦敦呼吸投诉的数量之间的关联。A&E访问包括急性呼吸道疾病的不太严重的情况,并通过床可用性不受限制。探访12个伦敦急症室用于治疗哮喘,呼吸道等投诉,都结合了许多年龄组的每日计数从期间1992 - 1994年的访问手动寄存器构成。泊松回归允许季节性,气象条件和流感流行用于评估的访问次数和六种污染物之间的关联:二氧化氮,臭氧,二氧化硫,一氧化碳,和颗粒测定黑烟(BS)和颗粒<10微摩尔(PM10)的中值空气动力学直径。制作的津贴测试的多样性之后,仍然存在于所有呼吸系统疾病和增加SO2访问之间的强关联:2.8%(95%可信区间(CI)0.7-4.9)增加访问次数为18微克x (-3) increase (10th-90th percentile range) and a 3.0% (95% CI 0.8-5.2) increase for a 31 microg x m(-3) increase in PM10. There were also significant associations between visits for asthma and SO2, NO2 and PM10. No significant associations between O3 and any of the respiratory complaints investigated were found. Because of the strong correlation between pollutants, it was difficult to identify a single pollutant responsible for the associations found in the analyses. This study suggests that the levels of air pollution currently experienced in London are linked to short-term increases in the number of people visiting accident and emergency departments with respiratory complaints.
