目的 :对包钢厂矿职工肺癌发病情况进行分析研究。方法 :采用回顾性队列研究 ,观察对象 775 5人 ,观察期为 1980 - 0 1- 0 1～ 1995 - 12 - 31,追踪观察对象职业变化、生存情况及死亡原因。测定职工作业环境中某些有害物质 (苯溶物、粉尘浓度等 ) ,并与当地居民的死亡率进行比较。结果 :包钢厂矿职工患恶性肿瘤高于当地居民 ,其中肺癌居首位 ,SMR明显超量 ,肺癌的死亡率与接触有害物质程度形成梯度 (P <0 0 1)。结论 :包钢厂矿职工肺癌发病与职业有关。
Objectives: To analyze the incidence of lung cancer among employees of Baogang Mine. METHODS: A retrospective cohort study was performed with 775 5 observations and the observation period was 1980 - 0 1 - 0 1 - 1995 - 12 - 31. The occupational changes, survival, and cause of death were followed. The determination of certain hazardous substances (benzene lysate, dust concentration, etc.) in the worker’s operating environment is compared with the mortality of local residents. Results: The employees of Baogang Mine suffered more malignant tumors than the local residents, among which the lung cancer ranked first. The SMR was significantly overweight. The mortality of lung cancer and the degree of exposure to harmful substances formed a gradient (P < 0 01). Conclusion: The incidence of lung cancer in employees of Baogang Mine is related to occupation.
