摘要
本文用寿命表法对江西某钨矿1321例尘肺病人累积活存情况和病情变化作了统计分析。得出30年累积活存概率为31％,累积活存概率与观察时间呈负相关;病情稳定概率为29％,累积稳定概率与观察时间呈负相关。同时对该矿不同生产时期产生的尘肺累积活存概率和累积稳定概率作了分析。
1321 cases of pneumoconiosis patients found in wolfram mine in Jiangxi were analyzed by life table method.The accumulated probability of survival obtained was 31% in 30 years.There existed a negative correlation between the accumulated probability of survival and the observation time.The accumulated probability of stability was 23% in 30 years, it was negatively correlated with the observation time.At the same time, the survival and stability rates of pneumoconiosis patients in different production period were also analyzed.
