To investigate the respiratory health effects of living near roadways.
We administered a questionnaire to Windsor school children. Exposure to roadways was defined as the total length of roadways within a 200 meter radius around the postal code of each household calculated using geographic information systems.
The adjusted odds ratios comparing the highest to the lowest exposure (roadway density) quintiles, were statistically significant for wheeze 1.23 (95% CI: 1.07 to 1.41) (P = 0.0041) and wheeze with dyspnea 1.27 (95% CI: 1.05 to 1.52) (P = 0.0125). Expressed as a continuous variable roadway density was associated with asthma, odds ratio 1.08 (95% CI: 1.012 to 1.149) equivalent to an 8% relative increase in the odds of asthma for an interquartile increase (0.6 km) in roadway density.
Residential traffic appears to adversely influence respiratory health.
研究居住在道路附近对呼吸系统健康的影响。
我们对温莎的学童进行了问卷调查。道路暴露定义为使用地理信息系统计算的每个家庭邮政编码周围200米半径内道路的总长度。
比较最高暴露(道路密度)五分位数与最低暴露五分位数时,喘息的校正比值比为1.23(95%置信区间:1.07至1.41)(P = 0.0041),喘息伴呼吸困难的校正比值比为1.27(95%置信区间:1.05至1.52)(P = 0.0125),具有统计学意义。以连续变量表示,道路密度与哮喘相关,比值比为1.08(95%置信区间:1.012至1.149),相当于道路密度四分位数间距增加(0.6公里)时哮喘患病几率相对增加8%。
居住环境中的交通似乎会对呼吸系统健康产生不利影响。
