目的 探讨晚孕妇女骨密度的变化。方法 用单光子γ射线吸收法测定 30 4例健康晚孕妇女桡骨远端 1/10点与中远端 1/3点的骨密度 ,并与同年龄组的健康非孕妇女相比较。结果 晚孕组骨密度均值低于非孕组 ,1/10点 I度和 II度骨量减少发生率均高于 1/3点。结论 相当一部分晚孕妇女不同程度的存在骨量减少现象 ,骨密度测定对发现孕妇骨密度降低有重要意义
Objective To investigate the changes of bone mineral density in pregnant women. Methods The bone mineral density (BMD) at 1/10 point and 1/3 point of the distal radius in 30 4 healthy pregnant women was measured by single photon gamma ray absorption method and compared with healthy non-pregnant women in the same age group. Results The mean BMD of late pregnancy group was lower than that of non-pregnant group, and the incidences of I and II degrees of bone loss at 1/10 were higher than 1/3. Conclusions A considerable part of the pregnant women have varying degrees of bone mass loss. The determination of bone mineral density is of great significance to the discovery of reduced bone mineral density in pregnant women
