背景：道路交通噪声和高血压的研究结果在效应大小、男女效应以及不同年龄组的影响方面存在差异。我们的目标是进一步探索这些关联。方法：该研究使用瑞典南部的横断面公共卫生调查数据，包括24,238名成年人（18 - 80岁）。我们使用地理信息系统（GIS）来评估当前居住地址的平均道路噪音（LAeq 24小时）。通过调整年龄、性别、BMI、酒精摄入量、运动、教育、吸烟和社会经济地位的logistic回归估计自我报告高血压的影响。结果：中等暴露类别（45 ~ 64 dB(A)）普遍存在中等暴露效应（OR近似为1.1），且无明显趋势。在bb0 - 64 dB(A)时效果更为明显（OR 1.45, 95% CI 1.04-2.02）。年龄改变了相对效应（p = 0.018）。在噪声水平为60 - 64 dB(A) （OR = 1.27, 95% CI 1.02 - 1.58）和bb0 - 64 dB(A) （OR = 1.91, 95% CI 1.19 - 3.06）的中年人（40 - 59岁）中观察到影响。这种效应在年轻人中也有，但在老年人中没有。没有注意到性别、原产国、睡眠紊乱或经济紧张的明显影响。结论：该研究支持高平均水平的道路交通噪音与中年人自我报告的高血压之间的联系。未来的研究应该使用特定年龄组的相对效应模型来解释患病率的差异。
Background: Results from studies of road traffic noise and hypertension are heterogeneous with respect to effect size, effects among males and females and with respect to effects across age groups. Our objective was to further explore these associations.Methods: The study used cross-sectional public health survey data from southern Sweden, including 24,238 adults (18 - 80 years old). We used a geographic information system (GIS) to assess the average road noise (LAeq 24 hr) at the current residential address. Effects on self-reported hypertension were estimated by logistic regression with adjustment for age, sex, BMI, alcohol intake, exercise, education, smoking and socioeconomic status.Results: Modest exposure effects (OR approximate to 1.1) were generally noted in intermediate exposure categories (45 - 64 dB( A)), and with no obvious trend. The effect was more pronounced at > 64 dB(A) (OR 1.45, 95% CI 1.04-2.02). Age modified the relative effect (p = 0.018). An effect was seen among middle-aged (40 - 59 years old) at noise levels 60 - 64 dB(A) (OR = 1.27, 95% CI 1.02 - 1.58)) and at > 64 dB(A) (OR = 1.91, 95% CI 1.19 - 3.06)). An effect was also indicated among younger adults but not among elderly. No apparent effect modification by gender, country of origin, disturbed sleep or strained economy was noted.Conclusion: The study supports an association between road traffic noise at high average levels and self-reported hypertension in middle-aged. Future studies should use age group - specific relative effect models to account for differences in prevalence.
