Abstract:
Objective:To understand the macronutrient content and influencing factors of donated breast milk in breast milk bank.Methods:A total of 458 first-time breast milk donors and their donated breast milk from June 2016 to June 2018 in Shanghai were selected as research objects by the convenient sampling method to determine the macronutrient content in donated breast milk. Multiple linear regression was used to analyze the influencing factors of the macronutrient content of donated breast milk.Results:In macronutrient content of 458 donated breast milk, the protein content was (0.95±0.24) g/dl, fat content was (4.03±1.25) g/dl, sugar content was (7.44±0.38) g/dl, dry matter was (12.75±3.16) g/dl and energy content was (71.12±11.33) kcal/dl.The results of multiple linear regression analysis showed that the time of milk donation and infant gender were the influencing factors of protein content in donated breast milk ( P<0.05). The time of milk donation, mode of delivery and season of birth were the influencing factors of the sugar content in donated breast milk ( P<0.05). The time of milk donation was the influence factor of energy content in donated breast milk ( P<0.05) . Conclusions:The content of macronutrients in donated breast milk in this study is lower than the demand for macronutrients in premature infants. The macronutrient composition of donated breast milk varies greatly among individuals, which is related to the time of milk donation, the mode of delivery, the infant gender and birth season of the baby. Therefore, further research is needed on how to add breast milk additives to donated breast milk in the later stage for targeted reinforcement to meet the growth and development needs of premature infants.
