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。
Objective: To explore the relationship between serum iron level and body length, body weight and so on, and to provide the basis for assessment standard of physical development in neonates. Methods: The content of iron in neonatal umbilical cord blood was measured by MB5 multi-channel atomic absorption spectrophotometer. The body length, body weight, head circumference and chest circumference at birth were measured by a unified national standard. Results: Serum iron levels were normal in 269 newborns. There was no correlation between serum iron level and serum iron level in mothers (P> 0.05). Serum iron level in newborns was significantly related to their birth height, body weight, head circumference, (P <0.05). Neonatal serum iron level was negatively correlated with prenatal weight gain (P <0.05). Conclusion: The level of serum iron in newborns is closely related to their physical development. The level of serum iron in pregnant mothers can not be directly used as an indicator of iron intake in neonates.
