The association between occupational noise exposure and hypertension is controversial. Thus, we aimed to assess the relationship between occupational noise exposure and hypertension. This was a case‒control study, and 509 cases and 1,018 controls from an automobile company were included between July and October 2013. Occupational noise exposure was defined as exposure to noise level ≥80 dB(A) (Lex, 8 h) or cumulative noise exposure (CNE) ≥ 80 dB(A)-years. To assess the associations of noise level and CNE with hypertension, univariate and multivariate logistic regression were performed to calculate odds ratios (ORs) and 95% confidence intervals (CIs). The restricted cubic spline function was used to establish dose‒response curves. A noise level ≥80 dB (A) (Lex, 8 h) was significantly associated with hypertension (OR 2.48, 95% CI 1.89-3.24). CNE ≥80 dB (A)-years was significantly associated with hypertension (OR 1.53, 95% CI 1.18-2.00). Nonlinear relationships between noise level, CNE and hypertension were found (p- nonlinear<0.05). Our study suggests that occupational noise exposure is a potential risk factor for hypertension in automobile company workers.
职业性噪声暴露与高血压之间的关系存在争议。因此，我们旨在评估职业性噪声暴露与高血压之间的关系。这是一项病例对照研究，于 2013 年 7 月至 10 月期间纳入了一家汽车公司的 509 例病例和 1018 例对照。职业性噪声暴露定义为暴露于噪声水平≥80 dB(A)（Lex，8 h）或累积噪声暴露（CNE）≥80 dB(A)-年。为了评估噪声水平和 CNE 与高血压之间的关联，采用单变量和多变量逻辑回归来计算比值比（ORs）和 95%置信区间（CIs）。采用限制立方样条函数建立剂量-反应曲线。噪声水平≥80 dB(A)（Lex，8 h）与高血压显著相关（OR 2.48，95%CI 1.89-3.24）。CNE≥80 dB(A)-年与高血压显著相关（OR 1.53，95%CI 1.18-2.00）。发现噪声水平、CNE 和高血压之间存在非线性关系（p-非线性<0.05）。我们的研究表明，职业性噪声暴露是汽车公司工人高血压的潜在危险因素。
