The composition of breast milk from brazilian mothers delivering low birthweight infants and its adequacy as a source of nutrients for this group has not yet been fully elucidated. A total of 209 milk samples from 66 women were analysed. The mothers were divided into three groups: G1, mothers delivering term babies of low birthweight (TSGA, n = 16); G2, mothers delivering preterm babies of appropriate birthweight (PTAGA, n = 20); G3, mothers delivering term babies of appropriate birthweight (TAGA, n = 30). The following factors were analysed: osmolarity, total proteins and protein fractions, creamatocrit, sodium, potassium, calcium and magnesium. Milk samples were collected 48 h and 7, 15, 30 and 60 days after delivery. The groups did not differ significantly in terms of osmolarity, total proteins and fractions, creamatocrit, calcium, magnesium or potassium throughout the study period. Sodium levels were higher in all samples from mothers of TSGA infants and in samples from mothers of PTAGA infants on the 7th, 15th and 30th days than in milk from the TAGA group. The authors consider the needs of the low birthweight and TAGA infants and that these high sodium levels may be necessary for growth of low birthweight infants.
巴西低体重儿母亲的母乳成分及其作为该群体营养来源的充足性尚未完全阐明。对66名女性的209份母乳样本进行了分析。母亲们被分为三组：G1组，分娩足月低体重儿的母亲（足月小样儿，n = 16）；G2组，分娩出生体重正常的早产儿的母亲（早产适于胎龄儿，n = 20）；G3组，分娩出生体重正常的足月婴儿的母亲（足月适于胎龄儿，n = 30）。分析了以下因素：渗透压、总蛋白和蛋白组分、乳脂率、钠、钾、钙和镁。在分娩后48小时以及第7、15、30和60天采集母乳样本。在整个研究期间，三组在渗透压、总蛋白及其组分、乳脂率、钙、镁或钾方面没有显著差异。在第7、15和30天，足月小样儿母亲的所有样本以及早产适于胎龄儿母亲的样本中的钠水平高于足月适于胎龄儿组母亲的母乳中的钠水平。作者考虑了低体重儿和足月适于胎龄儿的需求，认为这些高钠水平可能是低体重儿生长所必需的。
