摘　　要：目的小规模调查正常妇女骨密度的情况及变化规律。　方法应用双能X线吸收测量仪对本地区2 4 8例 2 0～ 86岁正常妇女进行L2 ～L4 腰椎部 (正位 )和左侧髋部骨密度测量。　结果正常妇女的骨峰值 ,腰椎部出现于 30～ 34岁 ,髋部出现于 2 0～ 2 4岁 ,4 5岁后腰椎部和髋部均显著下降。绝经后妇女骨密度下降明显 ,与绝经前比较有显著性差异 (P <0 .0 5 )。绝经初期骨丢失明显 ,以后随着年龄增长有所缓慢。　结论骨峰量的高低存在个体差异 。Objective To observe the Bone Mineral Density (BMD) value and its trend of change among normal women. Methods Here 248 normal women aged 20 ～ 86 years were investigted .The BMD value at L 2 ～ L 4 and that of the left hipbone were measured by dual energy X-ray absorptiometry. Results The average BMD value at L 2 ～ L 4 was peaked among women of 30 ～ 34 years old,while that of the left hipbone was peaked at 20 ～ 24 year old.The BMD value decreased drarratically after 45 years old at both sites,and decreased remarkably also after menopause. Significant difference existed between postmenopausal and premenopausal women(P<0.05).Menopause has higher influence on bone loss than age. Conclusion The peak of BMD value varied individually .Menopause is the main risk factor in causing bone loss.
