Bone mineral density changes in coal workers' pneumoconiosis / 中华劳动卫生职业病杂志

ABSTRACT

<p><b>OBJECTIVE</b>To observe the bone mineral density changes of coal workers' pneumoconiosis.</p><p><b>METHODS</b>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.</p><p><b>RESULTS</b>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.</p><p><b>CONCLUSION</b>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.</p>
