摘要
目的研究煤焦化企业机焦作业工人血压和心电图改变。方法某焦化企业机焦作业工人367人为观察组,某厂不接触影响循环系统有害因素的工人505人为对照组,进行对照研究。结果在工作场所空气中存在的主要职业病危害因素CO、SO2等低于国家容许浓度标准的情况下,观察组与对照组高血压检出率分别为4.1%和1.2%,差异有统计学意义(P<0.01)。心电图检出率分别为43.0%和27.5%,2组间差异有统计学意义(P<0.01);观察组心电图改变以窦性心律不齐和低电为主;工龄段比较,除1～5 a工龄段外,其他各工龄段心电图异常率差异皆有统计学意义;年龄段比较,除25岁以下年龄段外,其他各年龄段电图异常率与对照组相比,差异皆有统计学意义。结论煤焦化企业机焦作业工人血压和心电图异常率较高,为远期效应。
[Objective]To study the blood pressure and electrocardiogram（ECG） changes of coking plant workers.[Methods]A total of 367coking plant workers were recruited as observation group,another 505 workers without hazards exposure which affected their circulatory system from a factory were selected as control group for case-control study.[Results]The main occupational hazards in workplace air such as CO and SO2 concentrations were lower than the national standards,the detection rates of hypertension in observation group and control group were 4.1% and 1.2%,respectively;the difference was statistically significant（P〈0.01）.ECG detection rates were 43.0% and 27.5% respectively;the difference was also statistically significant（P〈0.01）;sinus arrhythmia and low tension voltage were primary ECG changes in the observation group.There were significant differences between subgroups of service length except for 1～5 years.Significant differences were also observed between various age groups except 25 years group when comparing with the control group.[Conclusion]As a long-term effect,abnormal rate of blood pressure and ECG changes of coking plant workers is relatively high.
