煤矿矿工尘肺与肺癌死亡Poisson回归分析

目的 探讨尘肺与肺癌的关系。方法 对涟邵矿务局3140例尘肺矿工进行回顾性队列分析，计算主要死因的标化死亡比（SMR），对尘肺与肺癌的关系进行Poisson回归分析。结果 尘肺矿工全死因与肺癌均高于对照人数，其中肺癌高于湖南省人群5倍；Poisson回归分析表明尘肺矿工肺癌与对照组的差别主要在25－44岁组。结论 支持尘肺与肺癌的相关关系。

Poisson regression analysis on pneumoconiosis and lung cancer mortality in coal miners

Objective To analyze the relationship between pneumoconiosis and lung cancer. Methods A retrospective cohort study was carried out on 3 140 coal miners with pneumoconiosis from Lianshao Mining Bureau. The SMR for the main mortality were calculated and relations between pneumoconiosis and lung cancer were analyzed by Poisson regression. Results SMR for all deaths and lung cancer deaths of coal miners with pneumoconiosis were both significantly higher than those of the control, and lung cancer mortality was 5 times higher than that of Hunan population. Poisson regression analysis showed that the main differences existed in the age groups of 25-44 years. Conclusion The mortality of lung cancer was markedly related to the incidence of pneumoconiosis.
