摘    要:
目的研究中国育龄妇女对还原铁粉的吸收利用率。方法以20名健康育龄妇女为研究对象,随机分为两组,以硫酸亚铁为对照,采用目前最准确的双标稳定性同位素技术,研究还原铁粉的吸收和利用。结果硫酸亚铁的标份利用率为5.8%,还原铁粉的标份利用率为2.1%,而红细胞血红蛋白掺入率分别为70.1%和91.3%,差异均有显著性意义。结论在典型中国膳食条件下,我国育龄妇女对还原铁粉的利用率为2.1%,而红细胞血红蛋白掺入率为91.3%。

关 键 词:标份利用率  育龄妇女  双标稳定性同位素

Abstract:
ObjectiveTo study the utilization of reduced iron powder in child-bearing-age women with traditional Chinese food.Methods 20 health child-bearing-age women were randomly divided into two groups. With ferrous sulfate as control, the utilization of reduced iron was measured using dual stable isotopes.Results The fractional utilization of iron in ferrous sulfate was 5.8%, while in reduced iron powder was 2.1%. The rates of absorbed iron incorporated into hemoglobin were 70.1% and 91.3% respectively. The differences were statistic significant.Conclusion With traditional Chinese food, the utilization of reduced iron in child-bearing-age women was 2.1%, and the rate of absorbed iron incorporated into red blood cells was 91.3%.
Keywords:fractional utilization   child bearing age women   dual stable isotopes
