To observe the bone mineral density changes of coal workers' pneumoconiosis.
We chose 150 cases of One-Triple coal workers pneumoconiosis in Jincheng Coal Mining Group, all of workers were male, of 55-years old-80 years old, an average of 67 years old. 10 years of age to grouping, Whole body bone mineral density and T value were measured by body dual-energy X-ray absorptiometry. We analyzed the BMD changes bone loss, osteoporosis occurrence.
The BMD of six parts were not declined obviously in One stage of coal workers' pneumoconiosis; the BMD of Chest bone, pelvis and spine were declined obviously in two stage of coal workers' pneumoconiosis; the BMD of six parts were declined obviously in Triple stage of coal workers' pneumoconiosis; The occurrence rate of bone loss was significantly higher in Two and Triple coal workers pneumoconiosis. The occurrence rate of osteoporosis was significantly higher in Triple coal workers pneumoconiosis.
With the increase in the severity of coal workers' pneumoconiosis, the BMD of six parts were declined, The occurrence rate of bone loss osteoporosis was significantly higher.
观察煤工尘肺患者骨密度的变化情况。
选取晋城煤业集团150例壹期至叁期煤工尘肺患者，均为男性，年龄55岁至80岁，平均67岁。按年龄10岁分组，采用双能X线骨密度仪测量全身骨密度及T值。分析骨密度变化、骨质丢失情况及骨质疏松的发生情况。
煤工尘肺壹期时六个部位的骨密度无明显下降；煤工尘肺贰期时胸骨、骨盆及脊柱的骨密度明显下降；煤工尘肺叁期时六个部位的骨密度均明显下降；煤工尘肺贰期和叁期骨质丢失发生率显著升高。煤工尘肺叁期骨质疏松发生率显著升高。
随着煤工尘肺病情严重程度增加，六个部位的骨密度下降，骨质丢失及骨质疏松发生率显著升高。
