Coal industry is one of the national pillar industries in China. A large number of coal miners are exposed to various occupational hazards, which might cause occupational disease. The aim of the study was to assess the quality of life (QOL) of coal miners in Xuzhou, China and explore influencing factors to QOL of coal miners.
Six hundred and twelve underground miners and 354 ground workers in one of coal mines of Xuzhou were enrolled in our study. The 36-item Short-Form Health Survey (SF-36) questionnaires were applied to evaluate the QOL of coal miners. Multivariate stepwise regression analysis was used to assess the potential impact factors on QOL.
The score of role limitations due to physical health problems (RP) dimension in underground miners was significantly lower than that of ground workers (P=0.005). Multivariate stepwise regression analysis showed that longer job tenure for dust exposure significantly lower coal miners' RP score. Comparing with normal populations, our subjects scored lower in both the physical health components (PHC) and the mental health components (MHC), and many factors accounted for it including job tenure for dust exposure, chronic disease, medical insurance, etc.
QOL of coal miners has been affected. Some measures might be taken by enterprise and coal miners themselves to protect the health of coal miners and improve their quality of life.
煤炭行业是中国的国家支柱产业之一。大量煤矿工人暴露于各种职业危害中，这可能导致职业病。本研究的目的是评估中国徐州煤矿工人的生活质量（QOL），并探讨影响煤矿工人生活质量的因素。
本研究纳入了徐州某煤矿的612名井下矿工和354名地面工人。采用36项简短健康调查问卷（SF-36）评估煤矿工人的生活质量。采用多元逐步回归分析评估对生活质量的潜在影响因素。
井下矿工身体健康问题所致角色受限（RP）维度得分显著低于地面工人（P = 0.005）。多元逐步回归分析显示，较长的粉尘接触工龄显著降低煤矿工人的RP得分。与正常人群相比，我们的研究对象在身体健康分量表（PHC）和心理健康分量表（MHC）上得分均较低，这是由许多因素造成的，包括粉尘接触工龄、慢性病、医疗保险等。
煤矿工人的生活质量受到了影响。企业和煤矿工人自身可采取一些措施来保护煤矿工人的健康，提高他们的生活质量。
