Lipids are the main source of calories and considered very important in infant growth. We aimed to compare fatty acid composition of term and preterm breast milk. This is the first study that compares the fatty acid levels of preterm and term breast milk in Turkish women.
Breast milk samples were obtained from mothers of term (n = 15) and preterm (n = 15) infants on postnatal days 3, 7, and 28. Fatty acid composition of human breast milk was determined longitudinally by gas-chromatography/mass spectrometry.
There Were 31 fatty acids measured in the milk samples. In the first month, 17 fatty acid levels had significant differences. In group comparison, some fatty acids (C14:0, C16:0, C18:1 and C20:5) had significantly increased in the preterm group (P = 0.041, P = 0.046, P = 0.027, P = 0.033, respectively), whereas myristoleic acid (C14:1) and eicosanoic acid (C20:0) had significantly increased in the term group (P = 0.015, P = 0.048, respectively).
Term and preterm milk have different compositions of fatty acids. Breast milk composition changes over time. As a general conclusion, breast milk provides the lipid requirements of infants.
脂肪是热量的主要来源，在婴儿生长过程中被认为非常重要。本研究旨在比较足月和早产母乳的脂肪酸组成。这是首次比较土耳其妇女足月和早产母乳中脂肪酸水平的研究。
在产后第 3、7 和 28 天，分别从足月（n=15）和早产（n=15）婴儿的母亲获得母乳样本。通过气相色谱/质谱法对人乳的脂肪酸组成进行纵向测定。
在乳样中测定了 31 种脂肪酸。在第一个月，有 17 种脂肪酸水平有显著差异。在组间比较中，一些脂肪酸（C14:0、C16:0、C18:1 和 C20:5）在早产儿组中显著增加（P=0.041、P=0.046、P=0.027、P=0.033），而豆蔻酸（C14:1）和二十烷酸（C20:0）在足月儿组中显著增加（P=0.015、P=0.048）。
足月和早产母乳的脂肪酸组成不同。母乳成分随时间而变化。总之，母乳提供了婴儿的脂质需求。
