应用寿命表方法，对某陶瓷厂尘肺患病情况、防尘效果进行了分析与评价，结果显示：累计观察４０周年，该厂１３４４名接尘工人检出尘肺２７２例，累积患病率高达４７．１２％；比较防尘前后尘肺发病情况，在相同观察时间（３０周年）内，防尘前后尘肺累积患病率分别为３８．３６％、９．１０％，差异显著（Ｐ＜０．０１）．并且防尘后发病人数较防尘前大幅度下降，降低尘肺发病７９．０７％，说明防尘效果明显，社会效益显著。
Application of life table method, a ceramic factory pneumoconiosis prevalence situation, the dust effect were analyzed and evaluated, the results showed that: the cumulative observation of the 40th anniversary of the factory 1344 workers exposed dust pneumoconiosis 272 cases, the cumulative prevalence rate of up to 47 .12%. Compared with the incidence of pneumoconiosis before and after dust prevention, the cumulative prevalence of pneumoconiosis before and after dusting were 38.36% and 9.10% respectively in the same observation time (30th anniversary) ). And the incidence of dust-proof after a substantial decline in dust than before, reducing the incidence of pneumoconiosis 79.07%, indicating that dust-proof effect, significant social benefits.
