目的探讨孕妇血清铁蛋白、叶酸、Zn水平与新生儿脐血红细胞内叶酸、血清铁蛋白、Zn水平以及新生儿体重之间的相互关系。方法孕24、28、32、36周以及产前检测孕妇肘静脉血、胎儿娩出后立即采集脐动脉血进行血清铁蛋白、Zn水平以及血红细胞叶酸含量检测,并测量新生儿体重,并根据孕妇产前的血红蛋白水平分为贫血组和非贫血组。观察各指标间的关系。结果贫血组与非贫血组血清铁蛋白、叶酸水平以及新生儿体重差异有显著性。结论检测孕母血中叶酸、血清铁蛋白水平可以间接反映新生儿叶酸、血清铁蛋白水平,对产前预防保健、改善新生儿预后有重要指导意义。
Objective To investigate the relationship between serum levels of ferritin, folate and Zn in pregnant women and folic acid, serum ferritin, Zn in newborn infants, and neonatal body weight. Methods The elbow venous blood of pregnant women was detected at 24, 28, 32 and 36 weeks of gestation and prenatal. Umbilical arterial blood was collected immediately after delivery to determine serum ferritin, Zn levels and folic acid levels of red blood cells. Prenatal hemoglobin levels were divided into anemia group and non-anemia group. Observe the relationship between the indicators. Results There was a significant difference in serum ferritin, folic acid levels and weight of neonates between anemia group and non-anemia group. Conclusion Detection of folic acid and serum ferritin in maternal blood can indirectly reflect the level of folic acid and serum ferritin in neonates, which is of great guiding significance in prenatal preventive care and neonatal prognosis.
