中铁四局集团尘肺病发病情况分析

[目的]了解中铁四局集团尘肺病发病状况及特点,为制定尘肺病防控策略提供依据。[方法]按全国尘肺流行病学调查方案对1963～2005年间诊断的尘肺病例建立数据库,SPSS10.0进行统计分析。[结果]1963～2005年,该企业累积尘肺病例502例,其中矽肺病例488例,占97.21%,矽肺死亡174例,病死率35.66%,发生矽肺的主要工种为凿岩工,占96.11%,1960年前接尘的矽肺病例占72.13%,矽肺病例的平均发病工龄29.44年,平均发病年龄54.37岁,随着年代的推迟,矽肺晋期率降低,发病工龄延长,发病年龄增加。[结论]该企业60年代开始采取的综合防尘措施取得了明显的效果,应继续强化粉尘治理,降低尘肺病发病率。

ANALYSIS ON THE PREVALENCE FEATURE OF PNEUMONOCONIOSIS IN CHINA TIESIJU CIVIL ENGINEERING GROUP

[ Objective] To understand the prevalence feature of pneumonoconiosis in China Tiesiju Civil Engineering Group so as to provide scientific basis for the formulation of pneumonoconiosis control strategy. [ Methods] According to national pneumonoconiosis epidemiology scheme, database was set up for casee who were diagnosed during 1963-2005. The date were analyzed by SPSS10.0. [ Results] There were 502 pneumonoconiosis cases in the enterprise from 1963 to 2005, in which there were 488 silicosis cases, accounting for 97.21%, 174 cases of them died and the fatality rate was 35.66%. Stone drilling was the major type of work which silicosis took place and accounted for 96.11%, the silicosis cases exposed to dust before 1960 accounted for 72.13% . The average incidence length of service and age of Silicosis were 29.44 years and 54.37 years. With the postponement Of time, the promoting rate of silicosis reduced, the incidence length of service and age increased. [ Conclusions] Comprehensive dustproof measures taken by the enterprise in the sixties have made obvious effectiveness, dust control should be strengthed sequentially to reduce the morbidity of pneumonoconiosis.
