背景：有人认为噪音暴露会增加患高血压的风险。道路交通是社区噪声暴露的主要来源。目的：研究城市居民区道路交通噪声暴露与高血压之间的关联。方法：研究人群由随机选择的 19-80 岁受试者组成。邮寄调查问卷提供了有关个人特征的信息，包括高血压的诊断。响应率为 77%，研究对象共有 667 名。使用噪声扩散模型和人工噪声评估确定每个人住所的室外等效交通噪声水平（Leq 24 小时）。个体噪声暴露以 5 dB(A) 为单位进行分类，从 < 45 dB(A) 到 > 65 dB(A)。 结果：根据年龄、吸烟、职业状况和房屋类型调整后的高血压比值比 (OR) 为 1.38（95% 置信区间 (CI) 1.06 至 1.80），噪声暴露每增加 5 dB(A)。这种关联在女性（OR 1.71；95% CI 1.17 - 2.50）和在该地址居住超过 10 年的人（OR 1.93；95% CI 1.29 - 2.83）中似乎更强。对分类暴露变量的分析表明存在暴露-反应关系。暴露于交通噪声与高血压之间的关联性最强的是那些对真实个人暴露的预期错误分类最少的人，如没有三层玻璃窗、住在老房子里、卧室窗户面向街道（OR 2.47；95% CI 1.38 至 4.43）。结论：我们的研究结果表明，暴露于住宅区道路交通噪声与高血压之间存在关联。
Background: It has been suggested that noise exposure increases the risk of hypertension. Road traffic is the dominant source of community noise exposure.Objective: To study the association between exposure to residential road traffic noise and hypertension in an urban municipality.Methods: The study population comprised randomly selected subjects aged 19-80 years. A postal questionnaire provided information on individual characteristics, including diagnosis of hypertension. The response rate was 77%, resulting in a study population of 667 subjects. The outdoor equivalent traffic noise level (Leq 24 h) at the residence of each individual was determined using noise-dispersion models and manual noise assessments. The individual noise exposure was classified in units of 5 dB(A), from < 45 dB(A) to > 65 dB(A).Results: The odds ratio (OR) for hypertension adjusted for age, smoking, occupational status and house type was 1.38 (95% confidence interval (CI) 1.06 to 1.80) per 5 dB(A) increase in noise exposure. The association seemed stronger among women (OR 1.71; 95% CI 1.17 to 2.50) and among those who had lived at the address for > 10 years (OR 1.93; 95% CI 1.29 to 2.83). Analyses of categorical exposure variables suggested an exposure-response relationship. The strongest association between exposure to traffic noise and hypertension was found among those with the least expected misclassification of true individual exposure, as indicated by not having triple-glazed windows, living in an old house and having the bedroom window facing a street (OR 2.47; 95% CI 1.38 to 4.43).Conclusion: The results of our study suggest an association between exposure to residential road traffic noise and hypertension.
