研究高骨密度（BMD）个体的背景因素可能为预防骨质疏松症提供有用的信息。我们研究了生殖因素与骨密度的关系。519名女性志愿者（327名绝经后妇女和192名绝经前妇女），年龄从21岁到74岁（平均52.3±11.8岁），通过定量计算机断层扫描和双x线吸收仪获得脊柱骨密度值。z评分由各5岁年龄组的平均骨密度计算，高骨密度和低骨密度定义为骨密度z评分为bb0 +1.5和
The study of background factors in individuals with high bone mineral density (BMD) may provide useful information in the prevention of osteoporosis. We investigated the relationship of reproductive factors to BMD. In 519 female volunteers (327 postmenopausal and 192 premenopausal women) ranging in age from 21 to 74 (mean 52.3 +/- 11.8) years, spinal BMD values were obtained using both quantitative computed tomography and dual x-ray absorptiometry. The z score was calculated from the mean BMD in each 5-year age group, and high BMD and low BMD was defined as BMD with z score >+1.5 and
