| 目的 比较不同性别高龄老人每年骨密度（BMD)变化情况。方法 对1006例高龄老人（男843例、女163例）进行股骨近端和腰椎正位BMD测定，并在12个月后再次进行BMD测定，计算?BMD。然后比较不同性别高龄老人在初次BMD和?BMD上的差异。结果 高龄男性股骨近端和腰椎正位的初次BMD都高于高龄女性（P<0.001)，但是不同性别高龄老人在?BMD上的差异无统计学意义（P >0.05);高龄老人股骨近端（除女性大粗隆外）BMD下降，而腰椎正位BMD上升。结论 不同性别高龄老人每年BMD的变化相似，其中股骨近端BMD呈逐年下降趋势，而腰椎正位呈逐年上升趋势。 |

| Objective To compare the yearly variance of bone mineral density (BMD) in the elderly people. Methods BMD of the proximal femur and the lumbar vertebrae was measured in 1006 elderly people ( 843 males and 163 females). The measurement was performed again after 12 months. The BMD difference between the two measurements was calculated. ?BMD between men and women were analyzed. Results The first BMD of the proximal femur and lumbar vertebrae in elder males was higher than that in elder females (P <0. 001). The difference of ?BMD between men and women was not significant (P > 0. 05). Except for greater trochanter in women, the BMD of proximal femur decreased, but the BMD of lumbar vertebrae increased. Conclusion The variance of BMD between elder men and women is similar. BMD of the proximal femur decreases year by year, but BMD of the lumbar vertebrae increases. |
