| 中文摘要: |
| 252例正常人，男性 117例，女性 135例，年龄范围20~78岁，每10岁为一个年龄组。用SPA测量桡骨BMD，用DEXA测量腰椎、左右髓骨 BMD及全身BMC，结果表明桡骨、腰椎及全身的峰值骨量年龄在 30~39岁，股骨颈、Ward三角的峰值骨量年龄在 20~29岁，没有性别差异。女性 40岁以后骨丢失速度明显快于男性， 到 60岁时，桡骨、股骨颈、Ward三角BMD及全身 BMC低于 T评分临界值。男性 70岁时股骨颈骨丢失低于 T评分临界值。 |
| 英文摘要: |
| 252cases of human being were studied in this paper．Of those，men were 117，women were 135, the average ages ranged from 20 to78．It was grouped according to decade. SPA was used to measure BMD of Radius．DEXA was used to measure BMD of Ap-spine，L-hip and total body BMC. The result showed that the ages of peak bone mass of Radius，Ap-spine and total body BMC are from 30 to 39. There were no sex difference．The ages of peak bone mass of BMD of L-neck and L-Ward were from 20 to 29．Bone loss of women over 40 years old was rapid than that of men at same age．The values of BMD of Radius, L-neck, L-Ward and total body BMC in women at 60 years old were lower than that of T-score. The value of bone loss of L-neck in men at 70 years old was lower than that of T score. |
