【摘要】：目的:探讨煤矿井下作业对工人心血管系统健康的影响。方法:以2013年6月至2014年8月在湖南省职业病防治院进行职业健康检查且资料完整的男性煤矿工人3 134例为研究对象。选择井下作业工龄2年及以上的工人为暴露组(n=2 370),无井下作业史的地面作业工人为对照组(n=764),比较两组心血管系统的异常率及其影响因素。结果:暴露组与对照组心电图异常检出率分别为37.6%和25.4%;高血压检出率分别为20.5%和13.4%;心率异常检出率分别为5.7%和6.0%;暴露组与对照组总的心血管系统异常率分别为49.8%和35.2%,差异均有统计学意义(均P0.05)。心血管系统异常的发生与调查对象的井下作业(OR=3.128,95%CI:1.969~4.970)、井下作业工龄(OR=1.205,95%CI:1.070~1.358)及工种(采掘工OR=1.820,95%CI:1.527~2.169;井辅工OR=1.937,95%CI:1.511~2.482;其他OR=3.291,95%CI:2.120~5.109)有关。结论:井下作业可增加煤矿工人心血管系统异常的风险,井下作业工龄越长,风险越高。
[Abstract]:Objective: to investigate the effect of underground operation on cardiovascular system health of workers. Methods: from June 2013 to August 2014, 3 134 male coal miners with complete data were studied. The abnormal rate of cardiovascular system and its influencing factors were compared between the exposed workers with 2 years or more and those with no underground working history as the control group. Results: the positive rate of abnormal ECG in exposure group and control group was 37.6% and 25.4%, the detection rate of hypertension was 20.5% and 13.4b, the detection rate of abnormal heart rate was 5.7% and 6.0%, and the total abnormal rate of cardiovascular system in exposed group and control group was 49.8%. The difference was statistically significant (P 0.05). The occurrence of abnormal cardiovascular system and the downhole operation of the object of investigation: CIW 1.9690.4.970, the downhole working age is 1.20595 CI: 1.0701.358) and the types of work (digger OR1.82095CIW 1.5272.169; well auxiliary worker OR1.93795CIW 1.5111.111.482; other OR3.29195CIW 2.1205.109). Conclusion: underground operation can increase the risk of abnormal cardiovascular system in coal miners, and the longer the working time is, the higher the risk is.
