The nutritional composition of milk obtained during the first month postpartum from 33 mothers delivering preterm and 18 mothers delivering at term was determined. Milk produced by mothers delivering preterm contained significantly higher concentrations of protein, sodium, and chloride, and significantly lower concentrations of lactose than milk produced by mothers delivering at term. The caloric concentration of milk produced by the two groups of mothers was similar, as were the concentrations of potassium, calcium, phosphorus, and magnesium. PT milk appears to approximate more closely the nutritional needs of the preterm infant than does other breast milk.
对33名早产产妇和18名足月产产妇产后第一个月的母乳营养成分进行了测定。早产产妇分泌的母乳中蛋白质、钠和氯的含量明显高于足月产产妇，而乳糖含量则明显低于足月产产妇。两组产妇分泌的母乳热量浓度相似，钾、钙、磷和镁的含量也相似。早产母乳似乎比其他母乳更接近早产儿的营养需求。
