目的：评价河南省４０余年来的尘肺病防治工作效果。方法：采用发病工龄、发病年龄、死亡年龄、死亡病程４项指标对全省１９９４年底前诊断的２４６７１例尘肺进行分析。结果：矽肺平均发病工龄、发病年龄、死亡年龄和死亡病程，９０年代初较６０年代初分别延长了７．６６年，１３．３４岁，１３．７７岁和８．２４年，煤工尘肺平均发病年龄、死亡年龄和死亡病程，９０年代较６０年代初分别延长了６．６２岁，１０．２３岁和７．９２年。结论：提示我省尘肺病防治工作效果较显著，矽肺的效果好于煤工尘肺，尘肺病对广大粉尘作业工人的危害程度已得到了较大程度的控制。
Objective: To evaluate the effect of pneumoconiosis prevention and control in Henan province for more than 40 years. Methods: 24671 cases of pneumoconiosis diagnosed by the end of 1994 in the whole province were analyzed by using four indicators of age of onset, age of onset, age of death and death. Results: The average incidence of silicosis, age of onset, age of death and course of death were prolonged by 7.66 years, 13.34 years, 13.77 years and 8.42 years respectively in the early 1990s and early 1960s, Age of onset, age of death and course of death were prolonged by 6.62, 10.23 and 7.92 years respectively in the 1990s compared with those in the early 1960s. Conclusion: It is suggested that the effect of pneumoconiosis prevention and cure work in our province is more obvious. The effect of silicosis is better than that of coal worker ’s pneumoconiosis. The extent of the hazard of pneumoconiosis to the dust workers has been controlled to a large extent.
