Dual photon absorptiometry (DPA) was used to measure the bone mineral density (BMD) of the lumbar spine in 510 normal women from the south of France. Long-term precision was 2.2%. BMD was stable in young adults and again in women over 70 years of age. Perimenopausal women at an average age of 51 years already evidenced a slight bone diminution (5%) compared to young adults and women within 2 years of the menopause already had a 10% diminution. The average rate of apparent bone loss in this cross-sectional study was 1% per year from age 45 to 65 years, but about 75% of this decrease occurred in the first decade after the menopause. Spinal BMD in our normal French population appears to be 5-10% lower than US values.
采用双能光子吸收法（DPA）测量了来自法国南部的510名正常女性腰椎的骨密度（BMD）。长期精密度为2.2%。骨密度在年轻成年人以及70岁以上女性中保持稳定。平均年龄51岁的围绝经期女性与年轻成年人相比已出现轻微骨质减少（5%），而绝经后2年内的女性骨质减少达10%。在这项横断面研究中，45至65岁期间明显骨质流失的平均速率为每年1%，但其中约75%的减少发生在绝经后的第一个十年。我们法国正常人群的脊柱骨密度似乎比美国人群低5% - 10%。
