煤矿工人上消化道疾病的现况研究

目的：探讨煤矿工人上消化道疾病的患病现况，方法：按照整群随机抽样的方法在山东兖州，河北开滦，辽宁铁法选取３０６人，以胃镜进行普查。结果：矿区工人总的上消化道疾病患病率为７７．８％，以红斑性胃炎为主，占各种上消化道疾病的４１．５％井下采煤和掘进作业工人的患病率高于井下其他作业工人，后者的患病率与井上工人的患病率一致，各矿区之间，以山东兖州的工人患病率最高，湖北开滦最低。结论 煤矿工人上消化道疾病患病

CROSS-SECTIONAL STUDY OF GASTRODUODENTAL DISEASES AMONG COAL MINERS

Objective To search the prevalence rate of gastroduodental diseases among coal miners.Methods 306 coal miners were chosen from three coal-mining areas in Shandong, Hebei and Liaoning with the method of cluster sampling. All the subjects were examined with gastroendoscope.Results The total prevalence rate of the gastroduodental diseases was 77.8%, which were dominated by erythematous gastritis standing 41.5%. The underground coal miners who were exposed to dust had the highest prevalence rate, but those unexposed to dust enjoyed the same prevalence rate as the coal miners working on the ground. In the three coal-mining areas, Shandong showed the highest prevalence rate among the workers and Hebei had the lowest.Conclusion The prevalence rate of gastroduodental disease in coal miners is higher than that in the ordinary people, and the risk of the diseases among underground coal miners may exist in the occupational exposure to dust.
