孕期血铁水平与新生儿身长、体重的相关分析

目的:探讨新生儿血清铁水平与身长、体重等的相关关系,为新生儿体格发育评估标准提供依据。方法:采用MB5多通道原子吸收分光光度计测定新生儿脐带血中铁的含量,采用国内统一标准测量新生儿出生时身长、体重、头围、胸围。结果:269例新生儿血清铁水平呈现正态分布,新生儿血清铁水平与母亲血清铁水平不存在相关性(P>0.05),新生儿血清铁水平与其出生时身长、体重、头围、胸围呈现相关性(P<0.05),新生儿血清铁水平与母亲产前增重呈负相关(P<0.05)。结论:新生儿血清铁水平与其体格发育密切相关,孕期母亲血清铁水平不能直接作为新生儿铁元素摄入的评价指标。

Analysis on correlation between serum iron level during gestational period and body height, body weight of neonates

Objective:To investigate the relationship between serum iron level and body height,body weight of neonates,provide a basis for design evaluation criteria of physical development for neonates.Methods:MB5 multi-channel atomic absorption spectrophotometer was used to measure the serum iron content in umbilical cord.The domestic standard criteria were used to measure body height,body weight,head circumference,and chest circumference of neonates.Results:The serum iron levels of 269 neonates distributed normally;there was no correlation between neonatal serum iron level and maternal serum iron level(P>0.05).Neonatal serum iron level was related to their birth height,weight,head circumference,and chest circumference,there were statistically significant differences(P<0.05).It was a negative correlation between neonatal serum iron level and prenatal increasing weight of mothers,there was statistically significant difference(P<0.05).Conclusion:Neonatal serum iron levels are closely related to their physical development.Maternal serum iron level during pregnancy can not be directly used as evaluative index of intake of neonatal iron element.
