目的了解产后42~60 d妇女骨密度影响因素。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,自制调查表调查孕期小腿抽筋情况、分娩方式、母乳喂养情况、产后钙摄入情况。结果产后骨密度存在不同程度下降,骨密度值与孕期小腿有无抽筋、分娩方式、喂养方式、产后钙摄入情况密切相关。结论孕期和产后补钙有助于预防产后骨密度下降。
Objective To understand the influencing factors of bone mineral density in women from 42 to 60 days postpartum. Methods Dual-energy X-ray absorptiometry was used to measure the bone mineral density (BMD) and the lumbar spine (L1-4). MES-motor function analyzer was used to analyze the muscle function of both lower extremities. The homemade questionnaire was used to investigate the calf cramps during pregnancy, mode of delivery, breastfeeding , Postpartum calcium intake. Results Postpartum bone mineral density decreased in varying degrees. There was a close correlation between BMD and pregnancy calf with cramps, mode of delivery, feeding mode and postpartum calcium intake. Conclusion Pregnancy and postpartum calcium supplementation can help prevent postpartum bone mineral density decline.
