【摘要】：目的通过分析大同某煤矿不同工种、不同开始接尘年代的接尘工人档案资料,揭示煤工尘肺发病规律。方法收集该煤矿1970年以来进入研究队列的4 771名煤矿工人作为研究对象,随访42年,分析不同工种、不同开始接尘年代的接尘工人发病率及各队列累计发病率。结果符合纳入标准共4 771人,其中患者193人,非患者4 578人,粗发病率为4.05%;掘进工、采煤工、混合工及辅助工的发病率依次为25.10%、8.50%、3.60%、0.19%,不同工种之间差异有统计学意义(χ2=644.12,P0.001);在相同的42年观察期内,掘进工、采煤工、混合工和辅助工的累计发病率分别为84.25%、41.04%、33.60%及1.03%,不同工种间累计发病率差异有统计学意义(χ2=543.73,P0.001);在相同32年观察期内,1970~及1980~开始接尘年代累计发病率分别为13.56%及13.51%,不同开始接尘年代累计发病率之间差异有统计学意义(χ2=217.12,P0.001)。结论掘进工累计发病率高于采煤工、混合工和辅助工;随着开始接尘年代的推移,接尘工人累计发病率有下降趋势。
[Abstract]:Objective to reveal the regularity of pneumoconiosis in coal miners by analyzing the file data of workers exposed to dust in different types of work and different ages of dust exposure in Datong Coal Mine. Methods 4771 coal miners who had entered the research cohort since 1970 were collected and followed up for 42 years. Results A total of 4,771 people met the inclusion criteria, including 193 patients and 4,578 non-patients, with a crude incidence of 4.05. The incidence rates of mixed workers and auxiliary workers were 25.100.50 and 3.600.19, respectively. There were significant differences among different types of work (蠂 ~ 2 ~ 2, 644.12, P 0.001). During the same period of 42 years, excavators and coal miners, The cumulative incidence rates of mixed workers and auxiliary workers were 84.25% and 1.033%, respectively. There were significant differences in cumulative incidence among different types of work (蠂 2, 543.73, P 0.001; in 1970- and 1980-), the accumulative incidence rates were 13.56% and 13.51%, respectively, in the same period of 32 years of observation. There was significant difference in the cumulative incidence rate in the beginning of dust exposure (蠂 2 217.12 P 0.001). Conclusion the cumulative incidence rate of tunneling workers is higher than that of coal miners, mixed workers and auxiliary workers, and the cumulative incidence rate of workers exposed to dust has a downward trend with the beginning of dust exposure.
