背景：流行病学研究报道了高血压与道路交通噪声暴露之间的关联，但噪声频率特征之间的关联尚不清楚。本研究调查了台湾中部地区道路交通噪声不同频率成分的暴露与高血压患病率之间的关系。方法：我们招募了 820 名在主要道路附近居住超过 3 年的居民。 2008 年同时测量了工作日 0900-1700 期间交通噪音的频率成分和交通流量。进行多重逻辑回归来估计诊断为高血压的比值比 (OR)，调整潜在的混杂因素和总交通流量。结果：高暴露组（>= 噪音水平中位数 [分贝，dB]）在 63 Hz、125 Hz 和 1000 Hz 下的噪音水平 与低暴露组（<噪声水平中位数[dB]）相比，高血压的 OR 分别为 2.77（95% 置信区间 [Cl]：1.17-6.52）、4.08（95% CI：1.57-10.63）和 1.98（1.00-3.92）（95% CI：1.00-3.92）。在所有受试者和男性中，由于暴露于 63、125 和 1000 Hz 的道路交通噪音，高血压患病率呈增加趋势。与暴露于 < 47 dB 的受试者相比，暴露于 125 Hz >= 51 dB 的受试者总数的 OR 为 4.65 (95% CI = 1.46-14.83)。结论：由于暴露错误分类可能存在偏差以及使用诊断的高血压存在偏差，这些结果表明，暴露于低频率和听力敏感频率的道路交通噪声可能与高血压有关，暴露于 125 Hz 的噪声可能与高血压有关。 患高血压的风险最大。
Background: Epidemiological studies have reported the association between hypertension and exposure to road traffic noise, but the association between noise frequency characteristics is not clear. This study investigated the association between exposure to different frequency components of road traffic noise and the prevalence of hypertension in central Taiwan.Methods: We recruited 820 residents living near main roads for more than 3 years. Frequency components of traffic noise and traffic flow rates during 0900-1700 on weekdays were measured simultaneously in 2008. Multiple logistic regressions were conducted to estimate odds ratios (ORs) for diagnosed hypertension, adjusting for potential confounders and the total traffic flow rate.Results: The high-exposure group (>= the median of noise levels [decibels, dB]) at 63 Hz, 125 Hz and 1000 Hz had ORs for hypertension of 2.77 (95% confidence interval [Cl]: 1.17-6.52), 4.08 (95% CI: 1.57-10.63) and 1.98 (1.00-3.92) (95% CI: 1.00-3.92), respectively, compared to the low-exposure group (< the median of noise levels [dB]). There was an increasing trend in the prevalence of hypertension by exposure to road traffic noise at 63, 125 and 1000 Hz in all subjects and in men. Total subjects exposed to >= 51 dB at 125 Hz had an OR of 4.65 (95% CI = 1.46-14.83) compared to those exposed to < 47 dB.Conclusions: With the possible bias of exposure misclassification and a bias from using diagnosed hypertension, these results suggest that exposure to road traffic noise at low and hearing-sensitive frequencies may be associated with hypertension and exposure to noise at 125 Hz may have the greatest risk for hypertension.
