井下环境因素与矿工高血压病相关性研究

The relationship between mine environment and hypertension in coal miners

目的了解井下环境因素与煤矿工人高血压病的相关性。方法采用整体随机抽样，对比井下工人1736例及地面工人825例高血压病发病情况。结果井下工人高血压患病率显著高于地面工人（23．91％与15．52％，χ^2=23．56，P〈0．001），井下工人患高血压病的危险性是地面工人的1．7倍（OR=1．71，95％CI1．38—2．13）。井下工人高血压患病率随井下工龄的增长而增加（χ^2=37．0，P〈0．001）。logistic回归分析显示，井下环境因素与矿工高血压病密切相关（OR=1．05，95％CI1．02—1．08）。结论井下工作环境是矿工高血压病发病的重要危险因素。

Objective To investigate the relationship between mine environment and hypertension in miners. Methods 1736 male miners who worked under the ground and 825 on the ground were recruited in this study. Prevalence of hypertension under the ground and on the ground miners was compared. Results Prevalence of hypertension of miners under the ground was 23.91% and on the ground was 15.52% （χ^2 = 23.56,P 〈0. 001 ）. Compared to miners on the ground, the relative risk of hypertension under the ground workers was 1.71 （95%CI 1.38 -2. 13）. Prevalence of hypertension was correlated to the years of ground working （χ^2 = 37.00, P 〈 0. 001 ）. The binary logistic regression showed significant relationship between mine environment and hypertension under the ground miners （OR = 1.05, 95% CI 1.02 - 1.08 ）. Conclusion The underground environment is an important risk factor hypertension to the miners.
