Analysis BMD measurement of 2593 men in Yuxi area

Objective The BMD of 2593 men in Yuxi area were determined for investigating normal reference data of male bone mineral density ( BMD) and peaking bone mass and analyze regularity of pathogenesis of osteoporosis,and provide scientific basis for prevention of OP. Methods The BMD of the distal one third of ulna of norr dominant arm were determined by DCS-600EX BMD detector produced by Japanese Aloka Corporation. 2593 objects were divided into different groups by 5 years,measure their BMD and the prevalence rate of OP. Results The peak value of bone mineral density was 0. 588 ± 0. 081(g/ cm2) in male,and that was showed in the age group of 30-. The prevalence rate of OP was 7. 41% in 20-,11. 70% in 25-,9. 68% in 30-,7. 49% in 35-,13. 84% in 40-,10. 93% in 45-,17. 20% in 50-,23. 59% in 55-,30. 22% in 60-,44. 32% in 65-,42. 34% in 70-,48. 94% in 75-,38. 89% in 80-. Conclusion In Yuxi area,the male BMD increased with ageing before 30 years old. The peak value of bone mineral density was 0. 588 ± 0. 081 (g/cm2),and that was showed in the age group of 30-,and then,the BMD decreased with ageing. The incidence of OP increased with ageing,but that decreased in 80-.
