Single-center Evaluation of Human Milk Quantity and Quality Over Five Years

This single-center retrospective observational study includes all human milk donors collaborating with the milk bank at České Budějovice Hospital between 2021 and 2025. Using anonymized data extracted from the hospital database, the study will quantify the frequency of donations and the individual and cumulative volume of donated human milk and will assess the impact of key maternal and perinatal factors - including age, BMI, parity, mode of delivery, and timing of donations - on the quantity and quality of donated milk, based on routine biochemical and microbiological parameters.
