【摘要】 目的 观察产后早期妇女骨骼密度的变化。方法 产后3~7天妇女60例，对照组31例，用双能X线骨密度仪测定L1-L4椎体的骨密度，分析妊娠哺乳对骨密度的影响。结果 产妇组L1骨密度明显低于对照组，P<0.025，L2、L3、L4骨密度虽较对照组降低，但差异无显著性，P>0.05。结论 妊娠期间存在不同程度的骨量降低现象，L1椎体骨密度测定较腰椎其余部位更为敏感。双能X 线骨密度仪对早期发现产妇骨量降低有一定临床价值。

    【Abstract】 Objective To observe the changing pattern of bone mineral density (BMD)in early period postpartum women. Methods 60 postpartum women were measured at their lumbar(L1-L4) with DEXA bone mineral density apparatus,31 nonpregnant women served as control group. The relation between pregnancy lection and BMD were analyzed. Results Compared with the control group,L1 BMD decreased significantly in the early postpartum women,(P<0.025),L2 L3 L4 BMD decreased but with little difference (P>0.05). Conclusions During pregnancy and early postpartum, women presented different degrees of low bone status and the detachment of L1 BMD is more sensitive than other parts of lumbar. The measurement of BMD has certain clinical significance for early detection of the decrease of BMD in early postpartum women. ......
