云南省尘肺发病和死亡发展趋势分析

目的 分析云南省尘肺病的发生发展特点,为有效防治尘肺提供科学依据.方法 应用尘肺病的累积病例的分布特征对云南尘肺发病和死亡发展情况进行分析,计算出发病年龄与尘肺病例数、死亡年龄与死亡病例数的回归方程.结果 现患病例中,尘肺病例主要以Ⅰ期患者为主;发病年龄与尘肺累计病例百分比之间呈“S“型曲线,回归方程为Ye=8.617 lgX-8.63;死亡年龄与尘肺累计死亡病例百分比的回归方程为Ye=102.394 lgX-2.35-10,表现为“双曲线型“.结论 30～55岁的粉尘作业工人为尘肺的易感人群,云南尘肺病有向老龄化、轻型化发展的趋势,尘肺病防治工作是有成效的.

Morbidity and Death Tendency of Pneumoconiosis in Yunnan

Objective]To analyze the pathogenesis and developing features of pneumoconiosis in Yunnan and provide scientific basis for pneumoconiosis prevention and control.Methods]The morbidity and death tendency of pneumoconiosis in Yunnan was analyzed based on the distributive features of the cumulative cases;the regression equations between the incidence age and pneumoconiosis cases and between the death age and dead cases were calculated.Results]Most of the present cases of pneumoconiosis were at stage I;it showed "S" curve between the incidence age and the accumulative cases,the regression equation was Ye=8.617 lgX-8.63;the regression equation between the death age and the percentage of accumulative dead cases was Ye=10 ~(2.394 lgX-2.335)-10,showing a hyperbola.Conclusion]Dust-exposed workers between the age of 30 and 55 belong to susceptive population of pneumoconiosis;pneumoconiosis in Yunnan has an aging and lighting tendency;it is proved that the preventive work is effective.
