噪声与粉尘联合作用对碳酸钙加工行业相关人员心电图及血压的影响

Effect of combined noise and dust on ECG and blood pressure of calcium carbonate processing staff

目的 了解噪声与粉尘联合作用对碳酸钙加工行业相关人员心电图及血压的影响。方法 2022年1—6月选择贺州市907名有粉尘或噪声暴露的碳酸钙加工行业相关人员与482名无粉尘或噪声暴露的行政人员作为研究对象。收集研究对象健康检查信息,分析噪声联合粉尘对碳酸钙加工行业工作人员心电图与血压的影响。结果 碳酸钙加工行业相关人员心电图异常与血压异常发生率分别为12.97%和20.84%,显著高于无粉尘与噪声暴露的行政人员异常率5.60%和11.20%,差异均有统计学意义(均P<0.05)。单因素分析结果显示,碳酸钙加工行业相关人员心电图异常与血压异常发生情况均受到从业者性别、年龄、体质量指数、工作年限及职业暴露种类的影响,此外,血压异常还受到工作人员吸烟或饮酒情况的影响(均P<0.05)。多因素logistic回归分析结果显示,相比于单纯粉尘暴露的碳酸钙加工行业工作人员,噪声+粉尘暴露的工作人员心电图异常风险更高(OR=4.728,95%CI:1.857~12.102),血压异常风险也更高(OR=5.076,95%CI:3.348~7.695)。结论 单纯粉尘作用与噪声+粉尘联合作用均会对碳酸钙加工行业相关人员的心电图与血压产生影响,其中噪声+粉尘联合作用的影响程度更为显著。

Objective To investigate the effects of combined noise and dust on ECG and blood pressure in calcium carbonate processing workers.Methods From January to June 2022,907 workers in the calcium carbonate processing industry exposed to dust or noise and 482 administrators without dust or noise exposure in Hezhou City were selected as the study subjects.The physical examination information of the subjects was collect and the impact of noise combined with dust on ECG and blood pressure of workers in calcium carbonate processing industry was analyzed.Results The incidence of abnormal ECG and abnormal blood pressure of related personnel in calcium carbonate processing industry(12.97%and 20.84%)was greatly higher than that of administrative personnel without dust and noise exposure(5.60%and 11.20%)(both P<0.05).The results of single factor analysis showed that the occurrence of abnormal ECG and abnormal blood pressure of relevant personnel in calcium carbonate processing industry were affected by gender,age,body mass index,working years and occupational exposure types of practitioners(all P<0.05).In addition,abnormal blood pressure was also affected by smoking and drinking among staff(P<0.05).The results of multivariate logistic regression analysis showed that compared with the workers in calcium carbonate processing industry exposed to dust alone,the workers exposed to noise and dust had a higher risk of abnormal ECG(OR=4.728,95%CI:1.857-12.102)and higher risk of abnormal blood pressure(OR=5.076,95%CI:3.348-7.695).Conclusion Both the simple dust effect and the combined effect of noise and dust will affect the ECG and blood pressure related to calcium carbonate processing industry,and the combined effect of noise and dust is more significant.
