Overview
Aim of study:
To evaluate the amount of protein in a set of human milk samples using mid-infrared human milk analyser after preterm labour during the first two months of lactation.
Methods:
Analysis of the donated milk samples between 24+0 and 35+6 gestational age (GA) was designed as prospective observational cohort trial. Two milk samples were analysed up to the discharge from the hospital, week 9 or loss of lactation. Analysis was performed using the MIRIS Human Milk Analyser (MIRIS AB, Uppsala, Sweden).
Results:
Total of 1917 human milk samples donated by 225 mothers after preterm labour were analysed. Group A (24–30 GA) contained 969 milk samples, the group B (31–35 GA) contained 948 milk samples. Mean true protein content decreased from 1.72 g/dL in group A and 1.65 g/dL in group B at the end of the first week of life to 1.1 g/dL in both groups at the end of the week 3, and remained stable with mean values around 1.0 g/dL up to week 9.
Conclusion:
There was no difference in the protein content of human milk as a function of term of premature delivery. Moreover the protein content was lower than expected and even decreased during first three weeks of lactation. We did not detect a significant difference in milk protein levels between group A (24–30 GA) and group B (31–35 GA).
