Samples from 1175 mother-infant pairs and 2966 donations to the UK North West Human Milk Bank between 2011-2017 were analysed.
Mean (sd) protein, fat, carbohydrate, and calculated energy, were 0.89 (0.24) g/dl, 2.99 (0.96) g/dl, 7.09 (0.44) g/dl, and 60.37 (8.41) kcal/dl respectively. Lactation time and z score negatively predicted protein and fat. Lower gestational age predicted fat, but not protein. There were no differences between preterm gestational age categories but highest levels of protein, fat and energy were found in preterm compared to term, and SGA compared to AGA HDM in the first 3 months of lactation, with the biggest differences seen between preterm SGA and term AGA groups.
SGA status, as well as prematurity, may be an important determinant of macronutrient content in early lactation. As bioavailability of macronutrients from HDM is uncertain, studies evaluating growth and body composition in preterm and SGA babies fed HDM are warranted.
