摘　　要：目的 探讨妊娠期不同方式钙干预对孕期妇女骨钙的影响。方法 对59名26～36岁健康孕妇进行膳食调查．随机分为三组．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 孕期每天膳食钙摄入量不足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、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 pregnant women aged from 26 to 36 Were observed by longitudinal follow-up, the research women were divided into three groups by random,with similar amount of energy and nutrient given excepting calcium. Results Calcium content in the traditional diet of pregnant women was lower than 450mg/d, in different groups and stages, no changes were found in serum calium and phosphorus contents. Calium retention in bone increased after calium supply. Conclusion Calcium content in the traditional diet of pregnant women is lower than RDA. The level of serum calium and phosphorus are fixed.
