不同孕期妇女跟骨骨量检测结果分析

Bone mineral density in pregnant women

目的 探讨不同孕期妇女骨量的变化 ,指导孕妇合理补钙。方法 采用UBIS5 0 0 0型超声成像骨量仪 ,测量 3 0 0例不同孕期健康妇女跟骨超声振幅衰减 (BUA)参数值 ,并与同年龄组非孕妇女结果进行比较。结果 中、晚期孕妇骨量均值均低于非孕及早孕期妇女 ,晚孕组与非孕组比较差异有显著性 (P <0 0 5 )。结论 孕期妇女存在不同程度骨量减少。

Objective To study the changes of bone mineral density in pregnant women Methods 300 pregnant women(100 early term, 100 middle term,and 100 late term pregnant women)were measured for broadband ultrasound attenuation(BUA)at their left calcaneum by VBIS 500 ultrasonic bone densitometry system 24 nonpregnant women served as control group Results BUA decreased in the 3 pregnant groups (63 35±4 83 dB/mHe, 61 98±3 44 dB/mHe,and 60 08±3 72 dB/mHe)but there were no significant differences between them ( P >0 05) Compared with the control group,the BUA in the late term pregnant group was significantly different( P <0 05) Conclusion During pregnancy,bone mineral density decreases to a varying extent It is of great significance to reduced bone mineral density in pregnancy by measuring BUA
