目的 了解福建省正常中老年人骨密度的水平和特点,为本地区骨质疏松症的防治提供参考。方法应用双能X线骨密度仪(DEXA)对福建省福州、泉州、龙岩3个地区共计2643例中老年人腰椎及股骨近端进行骨密度测定。结果 中老年人随着年龄的增加,各部位的BMD逐渐下降,女性更为明显,尤其是50岁左右绝经后妇女更加突出,50岁以后女性BND低于男性。结论 OP的防治重点应放在50岁女性;测定的腰椎BMD与临床情况不相符时,应参考股骨近端的BMD进行诊断;福建省中老年人应每天进行适当的体育活动,维持骨密度,抑制骨丢失,预防OP的发生。
Objective To understand the level and features of bone mineral density (BMD) in normal middle-aged and elderly people in Fujian Province and provide reference for the prevention and treatment of osteoporosis in this area. Methods Bone mineral density (BMD) of lumbar vertebra and proximal femur of 2643 middle-aged and elderly people in Fuzhou, Quanzhou and Longyan were detected by dual energy X-ray absorptiometry (DEXA). Results In middle-aged and elderly people, the BMD of each part decreased gradually with the increase of age, and the female was more obvious. Especially, the post-menopausal women of 50 years old were more prominent. The BND of women after 50 years old was lower than that of men. Conclusion The prevention and treatment of OP should be focused on the 50-year-old female. BMD of the lumbar spine should be diagnosed with reference to the BMD of the proximal femur when the BMD of the lumbar spine is not consistent with the clinical situation. Middle-aged and elderly people in Fujian Province should conduct appropriate physical activities daily to maintain the BMD, Inhibit bone loss, prevent the occurrence of OP.
