目的探讨孕妇缺铁状态及其对新生儿的影响 .方法对 187名孕妇血液和产时脐血的 5项铁参数进行跟踪 ,其中 77名分为补铁组和对照组 .结果 (1)随着孕周的增加 ,孕妇的SI、TS、SF下降 ,TIBC上升 ,Hb先下降后上升 ,t检验各项铁参数有显著性差异 (p <0 .0 5 ) ;(2 )孕妇缺铁越早 ,其脐血Hb、SI、TS、SF越低 ,TIBC越高 ,孕 2 0～ 2 6W与临产比较SI和SF均差异显著 (p <0 .0 5和p <0 .0 1) ,脐血SI和SF与母血SF正相关 (r=0 .31,p <0 .0 1和r=0 .18,p<0 .0 5 ) ;(3)补铁组脐血的Hb、SI、TS、SF比对照组高 ,TIBC比对照组低 ,两组SI、SF差异显著 (SI:p <0 .0 5 ;SF :p <0 .0 1) .结论孕妇缺铁性贫血发生率高 ,新生儿铁贮备降低 ,必须进行补铁治疗 .
Objective To explore the state of iron deficiency in pregnant women and its effect on newborns.Methods Five hundred iron parameters of blood and maternal umbilical cord blood of 187 pregnant women were tracked, of which 77 were divided into iron-supplemented group and control group.Results (1) Pregnant women with increased SI, TS, SF decreased, TIBC increased, Hb decreased first and then increased, t-test iron parameters were significantly different (p <0. 05); Early, umbilical cord blood Hb, SI, TS, SF, the lower the higher the TIBC, pregnancy 20 ~ 26W and labor were significantly different between SI and SF (p <0.05 and p <0.01) Umbilical cord blood SI and SF were positively correlated with maternal SF (r = 0.31, p <0.01 and r = 0.18, p <0.05). (3) Hb, SI, TS, SF were higher than the control group, TIBC was lower than the control group, the two groups of SI, SF significant difference (SI: p0.05 and SF: p0.01) .Conclusion The occurrence of iron deficiency anemia in pregnant women High rate, reduced neonatal iron stocks, iron therapy must be carried out.
