【摘要】：目的分析淮北某煤矿不同开始接尘年代、不同工种的接尘工人煤工尘肺(CWP)累计发病率的变化趋势。方法采用判断抽样方法,以1970—2014年在淮北市煤矿开始从事煤矿开采工作的12 152名接尘工人为调查对象,根据开始接尘年代分为1970~和1980~年组,根据接尘工种分为掘进组、采煤组、混合组和辅助组,采用寿命表法计算各组工人CWP累计发病率。结果 12 152名工人中,CWP患者594人,患病率为4.89%。在相同的第34年观察期内,1970~年组工人CWP累计发病率高于1980~年组(8.03%vs 5.45%,P0.01)。至2014年,掘进组、采煤组、混合组、辅助组工人CWP累计发病率分别为69.33%、40.53%、36.66%和19.70%。掘进组工人CWP累计发病率从第14年时间窗开始升高,采煤组工人从第16年时间窗开始升高,混合组和辅助组工人CWP累计发病率均从第18年时间窗开始升高。1970~年组第34年时间窗,采煤组工人CWP累计发病率最高,为33.83%(P0.004);混合组工人CWP累计发病率最低,为2.28%(P0.004)。1970~年组第44年时间窗,掘进组工人CWP累计发病率最高,为66.66%(P0.004);辅助组工人CWP累计发病率最低,为27.24%(P0.004)。1980~年组第34年时间窗,掘进组工人CWP累计发病率最高,为29.87%(P0.004)。结论随着开始接尘年代的推移,接尘工人CWP累计发病率的增长呈减缓趋势;不同开始接尘年代的不同工种接尘工人CWP累计发病率存在差异。
[Abstract]:Objective to analyze the change trend of cumulative incidence of coal workers' pneumoconiosis (CWP) in different dust exposure years and different types of work in a coal mine in Huaibei. Methods using judgment sampling method, 12 152 dust workers who began to work in coal mining in Huaibei coal mine from 1970 to 2014 were investigated. According to the age of dust exposure, they were divided into 1970 ~ and 1980 ~ years groups, and divided into driving groups according to the types of dust-exposed jobs. The cumulative incidence of CWP in coal mining group, mixed group and auxiliary group was calculated by life table method. Results there were 594 CWP patients in 12 152 workers, the prevalence rate was 4.89. In the same 34th observation period, the cumulative incidence of CWP in the workers of 1970-year group was higher than that in the 1980-year group (8.03 vs 5.45 P 0.01). By 2014, the cumulative incidence of CWP in tunneling group, coal mining group, mixed group and auxiliary group was 69.33% and 19.70%, respectively. The cumulative incidence of CWP in tunneling group and coal mining group began to increase from the 14th time window and the 16th time window respectively. The cumulative incidence rate of CWP in mixed group and auxiliary group increased from the 18th year time window to the 34th time window in 1970-year group. The cumulative incidence of CWP in the coal mining group was the highest (33.83%), the cumulative incidence of CWP in the mixed group was the lowest (2.28%, P 0.004), the cumulative incidence of CWP in the tunneling group was the highest (66. 66%, P 0.004), and the cumulative incidence of CWP in the auxiliary group was the lowest. The cumulative incidence of CWP in the excavating group was the highest, 29.87m, P0.004 and 29.87m, respectively, in the 34-year time window of the group from 27.24 to 1980 ~ 2000.The cumulative incidence of CWP in the tunneling group was the highest. Conclusion with the beginning of dust exposure, the cumulative incidence of CWP in dust-exposed workers tended to slow down, and the cumulative incidence of CWP in different types of workers was different.
