摘　　要：目的:研究分析妊娠早期妇女骨密度的变化情况,为临床合理补钙提供科学依据。方法:随机选择126例深圳居住的正常妊娠早期妇女为研究对象,按孕周不同分为两组,Ⅰ组为4～7周,Ⅱ组为8～11周,用定量超声骨密度仪(QUS)测定受检者足跟部骨密度(BMD)值;随机选择80例正常健康非妊娠妇女作为对照组。结果:妊娠早期两组骨密度值均较正常组稍高,但各组之间两两比较差异无统计学意义(P>0.01)。结论:妊娠早期妇女骨密度值并没有明显下降,妊娠早期是否需要补钙尚需进一步探讨。Objective： To provide scientific evidences for the calcium administration in clinic by the change of bone mineral density （BMD） level in early trimester of pregnancy. Methods： 126 pregnant women were divided into 2 groups aceording to gestational weeks, 4 7 weeks was group I, 8 - 11 weeks was group Ⅱ, BMD level of calcaneus was measured with QUS made in USA, 80 healthy young women were selected as control group at the same time. Results ： The BMD levels of two groups in early trimester of pregnancy were higher than that in control group, but there was no significant difference between group I and group Ⅱ （ P 〉 0.01 ） . Conclusion： The BMD level of hone mineral density in early trimester of pregnancy does not obviously decrease, so the problem of calcium administration needs further study and research.
