Urbanization and increasing road traffic cause exposure to both noise and air pollution. While the levels of air pollutants such as nitrogen oxides (NOx) have decreased in Sweden during the past decades, exposure to traffic noise has increased. The association with cardiovascular morbidity is less well established for noise than for air pollution, and most studies have only studied one of the two highly spatially correlated exposures. The Swedish Primary Prevention Study cohort consists of men aged 47 to 55 when first examined in 1970-1973. The cohort members were linked to the Swedish patient registry through their personal identity number and followed until first cardiovascular event 1970-2011. The address history during the entire study period was used to assign annual modelled residential exposure to road traffic noise and NOx. The Cox proportional hazards model with age on the time axis and time-varying exposures were used in the analysis. The results for 6304 men showed a non-significant increased risk of cardiovascular disease for long-term road traffic noise at the home address, after adjusting for air pollution. The hazard ratios were 1.08 (95% CI 0.90-1.28) for cardiovascular mortality, 1.14 (95% CI 0.96-1.36) for ischemic heart disease incidence and 1.07 (95% CI 0.85-1.36) for stroke incidence, for noise above 60 dB, compared to below 50 dB. This study found some support for cardiovascular health effects of long-term exposure to road traffic noise above 60 dB, after having accounted for exposure to air pollution.

瑞典队列中的道路交通噪音,空气污染和心血管事件。

城市化和不断增加的道路交通导致噪声和空气污染。在过去的几十年中,瑞典的空气污染物(如氮氧化物(NOx))水平有所下降,而交通噪声的暴露却有所增加。与噪声相比,与心血管疾病的关联还不如空气污染更明确,大多数研究仅研究了两个高度空间相关的暴露之一。瑞典初级预防研究队列由1970-1973年首次检查的47至55岁的男性组成。该队列成员通过其个人身份号码与瑞典患者登记系统相关联,并一直跟踪到1970-2011年第一次心血管事件。在整个研究期间的地址历史记录用于分配年度模拟住宅暴露于道路交通噪声和NOx的暴露。分析中使用了Cox比例风险模型,其中在时间轴上具有年龄,并且时变暴露量也是如此。调整空气污染后,针对6304名男性的研究结果显示,家庭住所内长期道路交通噪声对心血管疾病的危险增加并不显着。对于60 dB以上的噪声,心血管死亡率的危险比为1.08(95%CI 0.90-1.28),缺血性心脏病的危险比为1.14(95%CI 0.96-1.36),中风的发病率为1.07(95%CI 0.85-1.36)。 ,低于50 dB。这项研究在考虑了暴露于空气污染之后,发现了长期暴露于60 dB以上的道路交通噪声对心血管健康的影响。调整空气污染后,针对6304名男性的研究结果显示,家庭住所内长期道路交通噪声对心血管疾病的危险增加并不显着。对于60 dB以上的噪声,心血管死亡率的危险比为1.08(95%CI 0.90-1.28),缺血性心脏病的危险比为1.14(95%CI 0.96-1.36),中风的发病率为1.07(95%CI 0.85-1.36)。 ,低于50 dB。这项研究在考虑了暴露于空气污染之后,发现了长期暴露于60 dB以上的道路交通噪声对心血管健康的影响。调整空气污染后,针对6304名男性的研究结果显示,家庭住所内长期道路交通噪声对心血管疾病的危险增加并不显着。对于60 dB以上的噪声,心血管死亡率的危险比为1.08(95%CI 0.90-1.28),缺血性心脏病的危险比为1.14(95%CI 0.96-1.36),中风的发病率为1.07(95%CI 0.85-1.36)。 ,而低于50 dB。这项研究在考虑了暴露于空气污染之后,发现了长期暴露于60 dB以上的道路交通噪声对心血管健康的影响。冲程入射为07(95%CI 0.85-1.36),噪声大于60 dB则低于50 dB。这项研究在考虑了暴露于空气污染之后,发现了长期暴露于60 dB以上的道路交通噪声对心血管健康的影响。冲程入射为07(95%CI 0.85-1.36),噪声大于60 dB则低于50 dB。这项研究在考虑了暴露于空气污染之后,发现了长期暴露于60 dB以上的道路交通噪声对心血管健康的影响。
