摘　　要：目的了解妊娠晚期妇女骨密度分布规律,为指导孕妇钙营养提供依据.方法采用定量超声骨密度测定技术测定舟山海岛1 069名妊娠晚期妇女骨超声传导速度(SOS),并以T-Score值评价,利用方差分析和相关回归分析等方法分折其骨密度变化规律.结果1 069例妊娠晚期妇女中T值小于-1.0者391例,占总数的36.58%;20岁～、25岁～、30～、35～、38岁4个年龄组骨密度测定SOS均值分别为407 939,4118.48,4 154.05,4166.88(m/s),各年龄组SOS均值间差异有统计学意义(F=23.73,P＜0.001).骨SOS均值与年龄关系的最优模型为Y=3237.62+264.52ln(X)(r=0.91,F=77.97,P＜0.01).骨SOS值与BMI关系的最优模型为Y=-0.52X2+23.83X+3 855.66(r=0.89,F=12.72,P=0.0047).结论36.58%的孕妇骨矿物含量减少,其中1.40%达到诊断骨质疏松症的标准,孕妇在妊娠期间存在骨丢失现象,但其骨密度在20～38岁之间仍呈进行性增加.孕妇的体质指数与其骨矿物丢失程度正相关.Objective To learn the distribution discipline of the bone mineral density of the late pregnancy women and to provide the reference for guiding the calcium nutrition for the pregnancy women. Methods A quantitative ultrasound technoogy was develooped to measure the SOS of 1 069 late pregnancy women in Zhoushan archipelago, and the health status of the bone was evaluated through T - Score. The/MNOVA analysis and the correlation and regression analysis procedues were conducted to fine out the changing discipline of the bone mineral density. Results 391 women whose T- Score of SOS were less then - 1.0, which was 36.58 percent in total 1 069 late pregnancy women. The average values of SOS in age groups of 20～, 25～, 30～, 35 ～38 were respectively 4079.39, 4 118.48,4 154.05, 4 166.88（m/sec）. There was a significantly statistical difference between that in the four age groups（ F = 23.73, P〈0. 001 ）. The best fitness model between the average value of SOS and age was Y = 3 237.62 ＋ 264. 521n（X） （ r= 0.91, F = 77.97, P 〈 0.01 ）. The best finmes smodel between the average value of SOS and BMI was Y = - 0.52X2 ＋ 23.83X ＋ 3 855.66（ r = 0.89, F = 12.72, P = 0. 004 7）. Conclusion The mass of bone mineral decreased in 36.58 percent pregnancy women and that reached the criterion of osteoporosis in 1.40 percent pregnancy women. The pregnancy women lost some bone mineral during the pregnancy period. However, the bone mineral density increased prograssively from 20 to 38 years old. There is a relationship of positive correlation between the BMI and loss of bone mineral.
