摘要
目的：探讨妊娠期不同方式钙干预对孕期妇女骨健康的影响。方法：对59名26-36岁健康孕妇进行膳食调查,随机分为3组,即孕中期补钙组、孕晚期补钙组和对照组。在各组能量和营养素摄入相近的情况下,分别对研究组进行不同方式的钙营养支持干预。结果：孕期膳食钙摄入量每天不足450mg,孕妇血清钙、磷稳定,不随着钙摄入量的增加而改变;补充钙剂后可以增加骨钙含量。结论：孕妇膳食钙摄入量较低,但其血钙、血磷水平相对恒定,不受钙摄入量的影响,经补充钙剂有助于改善孕妇骨钙储备。
Objective： To study the effect of different calcium interference on the bone health during pregnancy. Methods： 59 pergnant women aged from 26 to 36 were observed by longitudinal follow - up. The women were divided into three groups by random, with similar amoune of energy and nutrient given excepting calcium. Results ： Calcium content in the traditional diet of pregnant women was lower than 450/mg/d. In different grops and stages, no changes were foung inserum calium and phosphorus contents. Calium retention in bone was increased after calium supply. Conclusion： Content in the traditional diet of pregnant women is lower than RDA. The levels of serum calium and phosphorus are fixed. Calium supply is necessary for pregnant women.
