中晚期妊娠钙营养干预对孕妇骨健康影响的探讨

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。

Efiect of calcium interence on the bone health of the pregnant women

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.
