目的 探讨噪声作业工人听力损失与高血压、心电图异常之间的关系.方法 采用判断抽样法,以在广州市汽车制造企业从事噪声作业且发生听力损失的555名男性工人为听力损失组,以同企业555名听力正常的男性工人为对照组.对2组工人进行纯音听力测定、血压测量和心电图检查,分析听力损失与高血压、心电图异常之间的关系.结果 听力损失组工人高血压患病率、心电图总异常率均高于对照组(P〈0.05).多因素Logistic回归分析显示:在调整了年龄、工龄、体质指数和饮酒等混杂因素后,听力损失组工人患高血压的风险高于对照组(P〈0.05),比值比(OR)及其95%可信区间(CI)为2.255(1.093~4.655);在调整饮酒混杂因素后,听力损失组工人发生心电图异常的风险高于对照组(P〈0.05),OR(95%CI)为1.408(1.027~1.930).结论 噪声作业工人发生听力损失可增加患高血压和心电图异常的风险.
Objective To explore the relationship between noise-induced hearing loss,hypertension and abnormal electrocardiogram (ECG) in noise-exposed workers.Methods A judgment sampling method was adopted to select 555 male workers with hearing loss as study group and 555 male workers with normal hearing as control group in the similar environment in an automobile manufacturing enterprise in Guangzhou.Pure tone audiometry,blood pressure measurement and ECG examination were performed in both groups to analyze the relationship between hearing loss and hypertension and abnormal ECG.Results The prevalence rate of hypertension and abnormal ECG was higher in the hearing loss group than the control group (P〈0.05).The multiple logistic regression analysis showed that after adjusting confounding factors such as age,seniority,body mass index,drinking et al,the risk of hypertension in hearing loss group was higher than the control group (P〈0.05) and the odds ratio (OR) was 2.255 [95% confidence interval (CI): 1.093-4.655],while adjusting the confounding factor of drinking,the risk of ECG abnormalities in hearing loss group was higher than the control group (P〈0.05) and the OR was 1.408 (95% CI: 1.027-1.930).Conclusion Workers exposed to noise with hearing loss increase the risk of hypertension and abnormal ECG.
