The aim of this study was to investigate the relationships between occupational noise exposure and blood pressure using self-reported occupational exposure and bilateral high-frequency hearing loss.
This study included 4548 participants aged 20 to 69 years from the National Health and Nutrition Examination Survey 1999 to 2004. On the basis of self-reported exposure status, participants were divided into the current, former, or never exposed groups. Bilateral high-frequency hearing loss was defined as the average high-frequency hearing threshold at least 25 dB in both ears.
The currently exposed participants had slightly increased diastolic blood pressure compared with those never exposed. Among previously exposed participants, those with bilateral high-frequency hearing loss had increased systolic blood pressure, heart rate, and the prevalence of hypertension compared with those with normal high-frequency hearing.
Although there were some significant results, the evidence was not consistent to support the associations between occupational noise exposure and blood pressure.
本研究旨在通过自报告职业暴露和双侧高频听力损失来探讨职业噪声暴露与血压之间的关系。
本研究纳入了 1999 年至 2004 年全国健康与营养调查中的 4548 名 20 至 69 岁的参与者。根据自我报告的暴露状况，参与者被分为当前暴露、既往暴露或从未暴露组。双侧高频听力损失定义为双耳高频听力阈值平均至少 25dB。
与从未暴露者相比，目前暴露者的舒张压略有升高。在既往暴露者中，与高频听力正常者相比，双侧高频听力损失者的收缩压、心率和高血压患病率均有所升高。
尽管有一些显著的结果，但证据并不一致，无法支持职业噪声暴露与血压之间的关联。
