晚孕妇女骨密度变化的研究

Changes of bone mineral density in late term pregnancy

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 。

Objective To study the changes of bone mineral density (BMD) in late term pregnancy. Methods\ BMDs of radius (distal 1/10 and 1/3) in 304 cases of late term pregnant women (aged 21-30) were determined by single photon absorptionmetry (SPA),and compared with nonpregnant healthy women of the same age. Results The BMDs of late term pregnant women were lower than those of nonpregnant, and the change at the 1/10 site was higher than that at the 1/3 site. Conclusions Bone loss exists in many late term pregnant women in different degrees; it is of great significance to reveal reduced bone density in pregnancy by measuring BMD.
