这项研究是加拿大安大略省温莎市一个更大的研究项目的一部分，该项目旨在研究环境空气质量与健康之间的关系。从1995年到2000年，我们评估了不同年龄和性别人群的空气污染与每日呼吸道住院之间的关系。污染物包括二氧化氮、二氧化硫、一氧化碳、臭氧、直径为10μm的颗粒物、雾霾系数和总还原硫。在控制了适当的混杂因素(温度、湿度和气压变化)后，我们使用时间序列和病例交叉方法计算了相对风险(RR)估计。两种分析的结果是一致的。我们发现，NO2、SO2、CO、COH或PM10与呼吸系统疾病的日常住院有关，尤其是在女性中。在0~14岁女性中，NO2的1d延迟效应(RR=1.19，病例交叉方法)，当日SO2的延迟效应(RR=1.11，时间序列)，以及病例交叉对CO的当前、1天和2天的延迟效应(RR分别为1.15，1.19，1.22)。时间序列分析显示，PM10对成年男性(15-岁)的呼吸入院有1天的延迟效应，相对危险度为1.18。COH对女性呼吸道住院有显著影响，尤其是对成年女性的2天延迟效应，时间序列分析和病例交叉分析的RRS分别为1.15和1.29。O_3和TRS与呼吸入院之间没有显著的关联。这些发现为政策制定者提供了目前在政府指定的“关注区域”因环境空气质量差而导致呼吸道住院的风险估计。
This study is part of a larger research program to examine the relationship between ambient air quality and health in Windsor, Ontario, Canada. We assessed the association between air pollution and daily respiratory hospitalization for different age and sex groups from 1995 to 2000. The pollutants included were nitrogen dioxide, sulfur dioxide, carbon monoxide, ozone, particulate matter ≤10 μm in diameter (PM10), coefficient of haze (COH), and total reduced sulfur (TRS). We calculated relative risk (RR) estimates using both time-series and case-crossover methods after controlling for appropriate confounders (temperature, humidity, and change in barometric pressure). The results of both analyses were consistent. We found associations between NO2, SO2, CO, COH, or PM10 and daily hospital admission of respiratory diseases especially among females. For females 0–14 years of age, there was 1-day delayed effect of NO2 (RR = 1.19, case-crossover method), a current-day SO2 (RR = 1.11, time series), and current-day and 1- and 2-day delayed effects for CO by case crossover (RR = 1.15, 1.19, 1.22, respectively). Time-series analysis showed that 1-day delayed effect of PM10 on respiratory admissions of adult males (15–64 years of age), with an RR of 1.18. COH had significant effects on female respiratory hospitalization, especially for 2-day delayed effects on adult females, with RRs of 1.15 and 1.29 using time-series and case-crossover analysis, respectively. There were no significant associations between O3 and TRS with respiratory admissions. These findings provide policy makers with current risks estimates of respiratory hospitalization as a result of poor ambient air quality in a government designated “area of concern.”
