早产人初乳和乳汁的总脂质含量和脂肪酸组成分析自初乳、过渡乳和成熟乳的24小时收集物的等分试样，所述初乳、过渡乳和成熟乳得自21名分娩了平均出生体重为1，049 ± 1，000的早产儿的妇女。38 g（平均值±. SEM [平均值的标准误差]）和平均胎龄为29 ± 10岁。0.4 wk.总脂含量随着哺乳时间的推移而显着增加（P < 0.001），从1.99 ±。0.25 g/dl至3.89 . ±. 0.28成熟乳中的克/分升。在脂肪酸模式方面，随着泌乳时间的延长，12：0和14：0的比例显著增加（P < 0.001），而16：0（P < 0.05）和18：1（P < 0.001）的比例显著降低。随着哺乳期的进展，在人初乳和乳汁中也描述了类似的成分变化。
The total lipid content and fatty acid composition of preterm human colostrum and milk were analyzed from aliquots of 24-h collections of colostrum, transitional milk and mature milk obtained from 21 women who had delivered premature infants with a mean birth weight of 1,049 .+-. 38 g (mean .+-. SEM [standard error of the mean]) and a mean gestational age of 29 .+-. 0.4 wk. The total lipid content increased significantly with time of lactation (P < 0.001), from 1.99 .+-. 0.25 g/dl in colostrum to 3.89 .+-. 0.28 g/dl in mature milk. With respect to the fatty acid pattern, the percentages of 12:0 and 14:0 increased significantly (P < 0.001), while those of 16:0 (P < 0.05) and 18:1 (P < 0.001) decreased significantly with the duration of lactation. Similar compositional changes have been described in term human colostrum and milk as the duration of lactation progresses.
