The Influence of Various Maternal, Infant and Environmental Factors on Human Milk Composition Among Lithuanian Women
The Influence of Various Maternal, Infant and Environmental Factors on Human Milk Composition Among Lithuanian Women
This study aims for characterization of different maternal, infant and environmental factors (e.g. maternal age, pregnancy duration, lactation period, baby gender, circadian rhythm, Holder pasteurisation, etc.) that influence human milk composition.
The study consists of three parts. In the first part the investigators aim to evaluate human milk macronutrient composition depending on the time after delivery and pregnancy duration.
In the second part the investigators aim to evaluate the circadian variation of human milk macronutrient and energy content depending on pregnancy duration.
In the third part the investigators aim to evaluate the influence of Holder pasteurisation on human milk macronutrient, metabolome and bioactive protein (lysozyme and lactoferrin) content.
