ABSTRACT
<p><b>OBJECTIVE</b>To observe the bone mineral density changes in coal workers' pneumoconiosis in Two and Triple stages with increasing ages.</p><p><b>METHODS</b>Chose 70 cases of coal workers pneumoconiosis in Two and Triple stages 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 ages to grouping, whole body bone mineral densities were measured by body dual-energy X-ray absorptiometry. We analyzed the BMD changes bone loss, osteoporosis occurrence.</p><p><b>RESULTS</b>Chest bone, pelvis, spine bone mineral densities of coal workers pneumoconiosis in Two and Triple stages were significantly decreased. We found that the rate of Pelvic BMD decline of coal workers' pneumoconiosis patients in Two stage was significantly faster after 65 years of age. In Different age groups of coal workers' pneumoconiosis patients in Two and Triple stages, incidence of bone loss and osteoporosis were significantly increased.</p><p><b>CONCLUSION</b>With the age increasing, Coal workers' pneumoconiosis in Two and Triple stages significantly accelerated the speed of the rate of BMD decline. This phenomenon was most obvious in the chest bone, pelvis, and spine.</p>

<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>
