对鞍钢三十一个主要工厂男职工的癌症和其他几种慢性病进行了比例死亡比的分析研究。查明这些工厂在1971—1981年期间死亡的工人2903名,并明确了死因。年龄别和死因别比例死亡率与鞍山男性人口年龄别比例死亡专率进行了比较。全癌、事故、白血病、恶性淋巴瘤、肺癌、肝癌、冠心病和脑血管病超出鞍山居民,这些疾病的标化比例死亡比(SPMR)分别为1.21(P<0.01)、1.21(P<0.01)、1.72(P<0.01)、2.31(P<0.01)1.46(P<0.01)、1.22(P<0.05)、2.10(P<0.01)、1.22(P<0.01)。同时也进行了癌症比例死亡比(PCMR)的研究,与比例死亡比研究结果相似。
An analysis of the proportion of deaths among cancer and several other chronic diseases at 31 major factory workers in Anshan Iron and Steel Research Institute was conducted. The number of workers who died in the 1971-1981 period in these factories was identified as 2903 and the cause of death was identified. The age-specific and the cause-specific mortality rates were compared with the age-specific mortality rates of the male population in Anshan. All patients with cancer, accident, leukemia, malignant lymphoma, lung cancer, liver cancer, coronary heart disease and cerebrovascular disease surpassed residents in Anshan. The SPMR of these diseases were 1.21 (P <0.01) and 1.21 (P <0.01) ), 1.72 (P <0.01), 2.31 (P <0.01) 1.46 (P <0.01), 1.22 (P <0.05), 2.10 (P <0.01) and 1.22 (P <0.01) respectively. A study of the proportion of cancer deaths (PCMR) was also conducted, similar to the proportionality death study.
