中文摘要:
      目的 通过对石雕作业农民工听力损害的检测,并探讨主要的影响因素,为相关部门提出有效的防控措施提供理论依据。方法 采用随机原则抽取济宁市嘉祥县6家石雕加工企业男性农民工112名,作为石雕作业组;选择非石雕作业农民工56人作为对照组。现场测定噪声强度及作业工人听力状况。结果 石雕作业农民工语音频段听力损伤发生率为88.39%,其中轻度聋为33.93%,中度聋为31.25%,重度聋为23.21%,显著高于对照组人群(χ2=88.659,P<0.001)。高频频率平均听阈在26dB以上者占96.43%,在41dB以上者占48.21%;随着作业人员工龄的逐渐增加,损伤所占比例均呈现增高。运用logistic多因素回归分析显示职业卫生培训(OR=0.973)、职业卫生防护措施(OR=0.827)是减少听力损伤的保护性因素,工龄(OR=1.687)、噪声强度(OR=5.382)、每天接触噪声时间(OR=1.601)是导致听力损伤的危险性因素。结论 石雕行业噪声对农民工听觉系统的危害较严重,相关部门应及时采取有效的综合防治措施。
英文摘要:
      Objective To study the hearing impairment for stone carving peasant workers and its meanings, and to provide theory basis for the relevant departments to put forward effective preventive and control measures.Methods 112 male peasant workers are taken randomly from 6 stone carving processing enterprises in Jiaxiang Country of Jining City as the stone carving group;and 56 non-stone-carving peasant workers as control group.The noise power and the hearing status of workers were measured onsite.Results The noise powers of main working procedure exceeded 86dB(A).The incidence rate of voice band hearing impairment for stone-carving peasant workers is 88.39%, of which the mild deaf take 33.93%, the moderate ones take 31.25%, and severe ones take 23.21%, which significantly higher than the control group(χ2=88.659, P<0.001).The ones whose average auditory threshold for high frequency above 26dB account for 96.43%, and above 41dB accounted for 48.21%;with the gradually increasing seniority of the workers, the percentage of impairment becomes higher.By logic multiple regression analysis, it shows that the occupational health training(OR=0.973) and occupational health protection measures(OR=0.827) are the protective factors for reducing hearing loss, while the seniority(OR=1.687), noise intensity(OR=5.382) and daily duration of noise contact(OR=1.601) are the risky factors for hearing loss.Conclusion The noise in stone carving industry does serious harm to the auditory system of peasant workers, and relevant departments should take effective actions for the prevention and treatment in time.
