早产儿母乳主要成分和矿物质动态分析

Consecutive Study of Nutritional Composition of Milk from Mothers of Preterm Delivery

纵向动态测定产后8周内早产儿母乳蛋白质、脂肪、乳糖、钾、钠、钙、磷、镁、铜、铁、锌含量。结果:蛋白质、钾、钠、铜、铁、锌含量随周龄增加而显著下降;平均摄入量除钙、磷、铁明显偏低外,其他成分均超过宫内胎儿增积量;产后4周内,钙、磷、镁、铜平均摄入量低于推荐摄入量;4周后蛋白质、钠、锌平均摄入量低于推荐摄入量。

The content of protein. fat.lactose, potassium. sodium, calcium, phos-phorus. magnesium, copper, iron, zinc inpreterm human mild was determined fromthe longitudinal samples during the first 8weeks of lactation. Changes in content, overtime were tested by analysis of variance.Protein, potassium, sodium. copper. iron,zinc content decreased significantly as lac-tation progressed. Based upon these da-ta,a preterm infant fed 200 ml per kg perday of its own mother's milk would rece- ive an excess of all substrates except cal-cium, phosphorus and iron over the esti-mated intrauterine accretion rates. Within4 weeks the first in the postpartum period.the avarage intake of calcium, phosphorus,magnesium and copper was lower thanthe recommended intake. Iron intake is notadequate.After 4 weeks,the avarage intakeof protein,sodium and zinc was lower thanthe recommended intake. The results mayoffer a basic datum for establishing pre-mature infant feeding and formulationof human milk fortifiers(HMF).
