0～6个月婴儿的血锌分析

Analysis on zinc of the serum in 0-6 months healthy infants

目的探讨0～6个月婴儿的血锌与月龄及喂养之间的关系。方法对119例0～6个月健康婴儿测定血清锌的浓度。首先把同为奶粉喂养的72名婴儿按月龄分为0～4个月和5～6个月两组，比较月龄对血锌的影响。另外把同一月龄（3～4个月）的58名婴儿按不同的喂养方式分为母乳喂养组和奶粉喂养组，比较喂养方式对血锌的影响。结果同为奶粉喂养的不同月龄两组婴儿的血清锌有明显的差异（P〈0．01）；同一月龄母乳与奶粉喂养儿之间血清锌也有明显的差异（P〈0.1）。结论0～6个月婴儿随着月龄的增加血清锌也增加，故没有明显的生长落后、临床症状的一般不予补锌，以防锌过量；另外母乳喂养比奶粉喂养儿的血锌高，因此提倡母乳喂养。

Objective To explore the correlativity of zinc and feeding way and age under six months .Methods Exam zinc content of serum in 119 healthy infants aged 0-6months. 72 infants with formula feeding were divided into two groups in different age （0-4m, 5-6m）.Compared the Zinc content in different age in the same feeding way. 58infants with the same age（3-4m） were divided into 2 groups in different feeding way. Compared the zinc content in breastfeeding and formula feeding .Result Zinc content will rise with age rising（P〈0.01）under six months. Zine content with breastfeeding is higher than formula feeding（P〈0.01）.Conclusion Zinc content of serum rise with age rising in 0-6m infants ,so don＇t excess adding zinc. Second： zinc content in breastfeeding is higher than formula feeding, so advocate breastfeeding.
