【摘要】 目的 :　研究孕妇缺铁导致新生儿缺铁的发病情况和补充铁剂的干预作用。方法 :　 44例孕妇分为对照组和铁剂组 ,孕中期开始分别服用安慰剂或铁剂。分别测定孕妇在服药前、服药后及新生儿的各项铁指标 :血清铁 (serum iron,SI)、总铁结合力 (total iron binding capacity,TIBC) ,转铁蛋白饱和度 (transferrin saturation,TS) ;血清铁蛋白 (serum ferritin,SF)。血红蛋白(Hb)值为临床资料。结果 :　对照组新生儿 Hb、SI、TS、SF平均值均低于铁剂组新生儿 ;对照组新生儿贫血发病率和贮铁不足率达 80 %、54.5% ,明显高于铁剂组。除母血 SF与新生儿 SI以外 ,孕妇与新生儿的 SI、TS、SF之间呈不同程度的显著正相关。孕末期铁剂组孕妇缺铁性贫血人数明显少于对照组 ;对照组孕妇孕末期 Hb、SI、TS、SF较孕中期进一步降低或维持原来的低水平 ,而铁剂组孕妇孕末期 Hb、SI、TS较孕中期有增加 ,SF未进一步降低。结论 :　孕妇与新生儿的铁营养状况密切相关 ,孕妇缺铁会导致新生儿缺铁。补充铁剂能减少孕妇及其新生儿缺铁更多还原

【Abstract】 Objective: To study iron deficiency (ID) of newborns caused by ID in pregnant women and the effect of iron supplementation. [WT5FZ]Methods: [WT5BZ]Forty four pregnant women were divided into control and iron groups randomly and began to take placebo or iron during median phase of pregnancy. Several indices including serum iron (SI), total iron binding capacity (TIBC), transferrin saturation (TS) and serum ferritin (SF) were measured. Hemoglobin concentrations were obtained from clinical records. [WT5FZ]Results: [WT5BZ]The Hb,SI,TS and SF of newborns in control group were lower than those of newborns in iron group. The incidence of anemia and insufficiency of iron store of newborns in control group were 80% and 54.5% respectively, which were higher than those of newborns in iron group. Except SI of newborns and SF of pregnant women, the SI, TS and SF of newborns were positively related to those of pregnant mothers. Fewer women in iron group suffering from iron deficiency anemia by the end of pregnancy compared to the control were noted. From median phase to the end of pregnancy the Hb, SI, TS and SF of pregnant women in control group remained constant or lower, while the Hb, SI and TS of the pregnant women in iron group got higher and their SF didnt decrease progressively. [WT5FZ]Conclusion: [WT5BZ]The relationship between the nutritional status of iron of pregnant women and newborns is closely related. ID of pregnant woman can lead to the ID of her newborn. Iron supplementation can reduce ID of pregnant women and newborns.更多还原
