THE EFFECT OF IRON SUPPLEMENTATION ON PREGNANT WOMEN AND NEWBORNS WITH IRON DEFICIENCY / 营养学报

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.
