目的:探讨母乳中铜、铁、锌、钙、镁等元素的含量及其与婴儿血中铜、铁、锌、钙、镁的相关性。方法:随机选择母亲与其婴儿各100例,在婴儿出生后3～4个月,分别对母乳与其婴儿末梢血进行铜、铁、锌、钙、镁元素的测定。结果:在纯母乳喂养的母亲乳汁中,元素的缺乏与其喂养的婴儿血液中元素的缺乏比较差异无统计学意义(P>0.05),呈高度的相关性。结论:母亲在孕期及哺乳期母乳不足或母乳中元素缺乏时,其喂养的婴儿体内就可能造成相关元素的缺乏。
Objective: To investigate the content of copper, iron, zinc, calcium, magnesium and other elements in breast milk and its correlation with copper, iron, zinc, calcium and magnesium in infant blood. Methods: A total of 100 mothers and their infants were randomly selected. The copper, iron, zinc, calcium and magnesium of breast milk and infant’s peripheral blood were measured respectively at 3 to 4 months after birth. Results: There was no significant difference in the elemental deficiency of breastfeeding mothers ’milk (P> 0.05), which was highly correlated with the lack of elements in their mothers’ breast milk. CONCLUSIONS: When mothers lack enough milk during pregnancy and lactation or lack elements in breast milk, their mothers may be infants’ lack of related elements.
