Metabolic balances were carried out in nine preterm very-low-birth-weight (VLBW) infants, five of whom were fed on expressed breast milk and four on a preterm formula. In 39 stool samples from these infants, there was a very close relationship between the fecal fat and the fecal water (r = -0.95; p less than 0.001), independent of the type of feed. This relationship was present over a very wide range of fat and water contents. Validation experiments confirmed the reproducibility and reliability of this relationship. The correlation is clinically and experimentally so close that measurement of stool water by freeze-drying a sample is an accurate indirect measure of fecal fat in VLBW infants when the daily stool weight was known.
对9名早产极低出生体重（VLBW）婴儿进行了代谢平衡研究，其中5名婴儿喂食挤出来的母乳，4名婴儿喂食早产配方奶粉。在这些婴儿的39份粪便样本中，粪便脂肪与粪便水分之间存在非常密切的关系（r = -0.95；p < 0.001），与喂养方式无关。这种关系在非常广泛的脂肪和水分含量范围内都存在。验证实验证实了这种关系的可重复性和可靠性。这种相关性在临床和实验上非常紧密，以至于当知道每日粪便重量时，通过冷冻干燥样本测量粪便水分是VLBW婴儿粪便脂肪的准确间接测量方法。
