2005年青岛市某电缆厂噪声作业工人心血管系统损害情况调查

目的]进一步观察噪声对心血管系统的影响。方法]2005年3月，在青岛市某电缆厂，检测作业场所噪声强度，对144名接触稳态噪声的作业人员进行职业健康检查。结果]高血压检出率接噪组为5．6％，对照组为0．9％（P〈0.01）；心电图异常率接噪组为22．2％，对照组为3．5Z（P〈0．01）。接噪组不同工龄者心电图异常率不同（P〈0．01），11～15年组高达62.5％。结论]电缆厂接触噪声的作业工人高血压患病率与心电图异常率增高。

Investigate the Injury of Noise on the Cardiovascular Systems of Workers in a Cable Factory of Qingdao

Objective]To observe the influence of noise on the cardiovascular system further.Methods]March,2005,in a electric cable factory of Qingdao, the noise intensity in the workplace was tested, occupational health inspection to 144 workers exposed to steady noise was carried on.Results]The positive rate of hypertension was 5.6% in the noise exposed group,0.9% in the control group (P<0.01);the abnormal rate of electrocardiogram (ECG) was 22.2% in noise exposed group,which was significantly higher than 3.5% in the control group (P<0.01).If the length of working was different in the noise exposed group,the abnormal rate of ECG was dissimilarity (P<0.01).In 11-15 years service group,the rate was up to 62.5%.Conclusion]In those workers exposed to steady noise of cable factory, hypertension and the abnormal rate of ECG increased.
