[目的]探讨噪声对作业工人健康的影响。[方法]选择某石化企业142名接噪工人作为暴露组,另选择某炼化企业122名非噪声作业人员作为对照组,对听力测定以及心电图、血压检查结果进行对照分析。[结果]暴露组听力损失率为30.3%,心电图异常率为20.4%,血压升高率为23.2%,均高于对照组(10.7%,11.5%,9.8%),两组资料经χ2检验,差异有统计学意义(χ2=15.12,P﹤0.01;χ2=8.34,P﹤0.01;χ2=3.85,P﹤0.05)。[结论]噪声对作业工人听力有明显损害,且随工龄的增加危害程度有加重的趋势;同时对心血管系统也有影响。
[Objective] To investigate the noise impact on the health of workers. [Method] A total of 142 non-noise workers in a petrochemical enterprise were selected as the exposure group. Another 122 non-noise workers in a petrochemical enterprise were selected as the control group, and the results of audiometry, electrocardiogram and blood pressure examination were compared. [Results] The hearing loss rate was 30.3%, the ECG abnormality rate was 20.4% and the blood pressure increased rate was 23.2% in the exposure group, which were higher than those in the control group (10.7%, 11.5% and 9.8% The difference was statistically significant (χ2 = 15.12, P <0.01; χ2 = 8.34, P <0.01; χ2 = 3.85, P <0.05). [Conclusion] The noise has obvious damage to the hearing of working workers, and it tends to aggravate with the increase of working age. At the same time, it also affects the cardiovascular system.
