Changes in Human Milk Fatty Acid Composition During Lactation: The Ulm SPATZ Health Study.

ABSTRACT: The lipid fraction of human milk provides the infant with the fatty acids that are necessary for optimal growth and development. The aim of this study was to investigate the fatty acid composition of human milk at three time points during lactation and its change over time using appropriate statistical methods. Human milk samples from breastfeeding mothers at 6 weeks (n = 706), 6 months (n = 483), and 12 months (n = 81 with all three time points) were analyzed. Centered log-ratio (clr) transformation was applied to the fatty acid data. Principal component analysis (PCA) and generalized linear model-based repeated measure analysis were used to assess changes over time. The total lipid content was significantly higher at 6 months (β = 0.199, p < 0.029) and 12 months of lactation (β = 0.421,
