摘要
目的：调查和分析从事石油化工作业职工恶性肿瘤死亡状况。方法：资料由石油化工厂人事部门提供，死因按ＩＣＤ－９分类，标化死亡率按１９６４年第二次全国人口普查资料计算，病例均为一、二级诊断。结果：该厂２１年间各种死因的年平均死亡率为１５６．５８／１０万，其中恶性肿瘤在全死因位次占第一位，恶性肿瘤死亡率随年龄而上升，不同民族恶性肿瘤死亡率不同（χ２＝６．６７，Ｐ＜０．０５）。结论：石油化工厂职工白血病死亡率超过参照人群，其ＳＭＲ＝１５１，Ｐ＜０．０１，表明该厂职工患白血病的危险性增高。
Objective: To research the malignant tumor mortality of those workers who engaged in petrochemical occupation. Methods: The relevant data were provided by personnel department of Urumqi petrochemical workers factory and the cause of death was classified by ICD 90. To calculate the standardized mortality rate, we used the information of the second national census in 1964. All cases were diagnosed according to the first diagnosis or the second diagnosis. Results: During the past 21 years, the average crude death rate was 156.58/100000 per year, and the mortality rate of malignant tumor was the highest. With the age increasing, the mortality rate raised accordingly, and the mortality rate was not the same in different nationalities (χ 2=6.67, P<0.05). Conclusions: The mortality rate of leukemia in Urumqi petrochemical workers was higher than that of reference population, SMR=151, P<0.01.It shows that the risk of liability to leukemia is higher in this plants workers.
