摘要
作者纵向追踪观察80名健康初孕妇女,于不同孕期抽取静脉血并留取部分脐血进行8项有关铁营养指标的测定,并了解孕期膳食摄入情况。观察到:随孕龄的增加,孕妇铁贮备显著降低,故铁缺乏症的检出率有增高的趋势;孕期总铁摄入量与孕期母血多项指标的变化幅度、孕期铁缺乏症的程度与脐血铁蛋白均存在密切关系;母血血清铁与脐血铁蛋白呈正相关。提示在孕期及时调整膳食结构、投予铁剂或铁强化食品是防治孕妇铁缺乏的重要措施。
Eight parameters about iron nutrition were observed longitudinally in eighty pregnant women from the first trimester to delivery. Their nutrients intake were recorded at the same time. It was noted that serum iron store (ferritin) decreased markedly in the course of pregnancy and the incidence of iron deficiency increased. Total iron intake was closely related to the variation of these parameters, the degree of iron deficiency in pregnant women and the content of cord ferritin. Iron in maternal serum is correlated to ferritin in the cord blood. It suggested that natural food abundant in iron, or food fortified with iron should be taken in early pregnancy to prevent iron deficiency of mothers.
