目的了解产后42～60 d妇女骨密度恢复情况,了解产后骨密度与分娩方式的关系。方法利用双能X线吸收仪检测髋关节骨密度、L1-4腰椎骨密度,利用MES-运动功能分析仪进行双下肢肌肉功能分析。结果产后骨密度存在不同程度下降,与对照组相比,剖宫产妇女骨密度下降明显。结论自然分娩、产后补钙、喝牛奶可预防骨密度下降。
Objective To understand the recovery of bone mineral density in women from 42 to 60 days postpartum and to understand the relationship between postpartum bone mineral density and mode of delivery. Methods Dual-energy X-ray absorptiometry was used to detect hip joint BMD and L1-4 lumbar spine BMD. MES-motor function analyzer was used to analyze muscle function of both lower extremities. Results Postnatal bone mineral density decreased to varying degrees, compared with the control group, women with cesarean section bone mineral density decreased significantly. Conclusions Natural delivery, postpartum calcium supplement and drinking milk can prevent the decrease of bone mineral density.
