【摘要】 目的了解职业铍接触人员恶性肿瘤的发病情况,探讨铍接触与肿瘤发病之间的关系。方法采取回顾性队列研究方法对554名铍接触工人和514名对照工人进行流行病学调查。结果观察队列肺癌死亡率在肿瘤死因中居于首位,为对照队列的2.92倍,差异有显著性。观察队列肺癌死亡率随接触年限增多而增大,并与工种岗位有关。接触铍且吸烟者肺癌发病明显高于接触铍但不吸烟者。结论铍作业工人的肺癌死亡率明显高于一般人群,与接触年限、工种以及吸烟等因素有密切关系。更多还原

【Abstract】 Objective To study the prevalence of the tumors in occupation al Be exposed workers, understand the relationship between the Be exposure and the tumor prevalence. Methods A retrospective survey was taken in 5 54 people exposed to Be and 514 controls. Results The highest mo rtality in the study group was lung cancer, RR=2.92, there was a significant dif ference between the exposed group and control. Moreover, there was a correlatio n between lung cancer mortality and the years exposed to Be and work position. The workers exposed to Be with smoking habit had much higher lung cancer morbidi ty than those exposed to Be without smoking. Conclusion The wor kers exposed to Be have a higher mortality than average population. There is a relationship between lung cancer and the years exposed to Be, work position, and smoking.更多还原
