摘要：Although benefits of breast-feeding have been known for a long time and breast milk is considered as ideal nutrition for infants, the composition of breast milk is still being studied, since breast milk differs among mothers and populations, as well as during different times of lactation. Further, no study has been performed among lactating women in Latvia during recent years. The objective of the study was to determine the breast milk composition and influencing factors among lactating women in Latvia in different lactation periods, as well as to compare the results with data from other countries. Fifty breast milk samples were obtained from 44 mothers (on the 5th-7th and 11th-28th day of lactation), whose neonates were treated in the Neonatal Care Unit, Children’s Clinical University Hospital, Rīga. Milk analysis (pH, density, protein, fat, and lactose concentration) was performed in the Latvia University of Agriculture. Breast milk composition among lactating women in Latvia on the 5th-7th lactation day more resembled transitional milk containing a higher amount of protein and a lower amount of fat. The composition of the studied milk samples on the 11th-28th lactation day was comparable to data from other countries. Concentration of lactose was correlated with neonatal weight and not gestational age.
