【摘要】 采用病例对照研究的方法,探索包钢职工白血病死亡与生产过程中的职业有害因素和生活环境因素的关系。白血病20例,病例与对照的比例为1:4。研究的因素包括九种职业有害因素以及受教育程度、经济收入、居住条件等一般社会经济状况,吸烟、饮酒、饮食、疾病史、医疗史和医用诊断X线照射情况等。直接面询收集的资料用IBM微机处理,主要用成组和非成组分析方法计算比数比(OR值)。根据OR值计算结果,仅见白血病死亡与高硅粉尘、煤焦油逸散物和高温作业有显著性关联,未见与生产环境中放射性因素和其他生活环境因素有任何关联。更多还原

【Abstract】 The probable relationship between the leukaemia death and γ-ray radiation, radioactive 234-TH pollution and other occupational harmful factors from the factory were studied. The number of case and control were 20 and 76, respectively. The factors for study included education level, income, living space, smoking, alcohol consumption, diet, history of illness and medical X-ray exposure besides the 9 varieties of occupational harmful factors. All data were collected through direct interview. The gathered data were analyzed by methods of matched and unmatched studies in IBM computer, and expressed by odds ratio(OR). It showed that leukaemia appeared to be nothing to do with single γ-ray exposure or pollution of radioactive dust contained 234-TH or even combination. However, leukaemia death did associate with dust contained silica at high concentration, coal tar effluent and hot environment.更多还原
