目的：研究环境空气污染在加重温莎，安大略.Methods心血管疾病住院治疗中的作用：从1995年4月1日至2000年12月31日，从所有温莎医院获得每日心脏病住院人数，并与环境空气污染物浓度和天气变量相关。住院治疗的每日计数的对数回归污染物的水平，调整后的季节，每周周期，和天气变量，使用时间序列分析与自然样条作为smoothingfunctions.Results：在所有的污染物考虑，二氧化硫（SO2）有最强的影响心脏病住院大于或等于65岁的年龄组。当日二氧化硫水平的每日入院百分比增加2.6%（95%CI：0.5-6.4），2天平均水平的增加4.0%（95%CI：0.1-6.9），3天平均水平的增加5.6%（95%CI：1.5-9.9），四分位数范围增加19.3 ppb。当颗粒PM10被纳入模型中，二氧化硫的贡献效应仍然显着大于或等于65岁的年龄组为所有三个levels.Conclusions：二氧化硫的短期影响显着相关的每日心脏病住院大于或等于65岁的人生活在温莎。由于温莎是一个边境城市，建议进行额外的监测和评估，以确定2001年9月11日事件后边境交通拥堵加剧是否导致空气质量和由此产生的健康影响恶化。
Objective: To examine the role that ambient air pollution plays in exacerbating cardiovascular disease hospitalization in Windsor, Ontario.Methods: The number of daily cardiac hospital admissions was obtained from all Windsor hospitals from April 1, 1995 to December 31, 2000 and linked to concentrations of ambient air pollutants and weather variables. The logarithm of daily counts of hospitalization was regressed on the levels of pollutants, after adjusting for seasonal, weekly cycles, and weather variables using time series analysis with natural splines as smoothing functions.Results: Of all the pollutants considered, sulphur dioxide (SO2) had the strongest effect on cardiac hospitalization among the greater than or equal to65 age group. The percentage increase in daily admission was 2.6% for current day sulphur dioxide level (95% CI: 0.5-6.4), 4.0% for 2-day mean level (95% CI: 0.1-6.9), and 5.6% (95% CI: 1.5-9.9) for 3-day mean level for an increase in interquartile range of 19.3 ppb. When particulate PM10 was included in the model, the contributing effect of sulphur dioxide remained significant for the greater than or equal to65 age group for all three levels.Conclusions: Short-term effects of sulphur dioxide are associated significantly to daily cardiac hospital admissions for people greater than or equal to65 years of age living in Windsor. Since Windsor is a border city, additional monitoring and assessment is recommended to determine if air quality and resultant health effects have deteriorated since traffic congestion at the border has increased following the events of September 11, 2001.
