Abstract

Objectives: Optimal macronutrient (protein, fat, carbohydrate) values in human milk (HM) are essential for the healthy growth of infants, particularly those with very low birth weight. This study aimed to investigate the correlations between macronutrient content in HM and the characteristics of donations in the Croatian HM bank.

Methods: A total of 211 pools of HM from 51 donors were included. Analysis of HM was performed on MIRIS Human Milk Analyzer (Miris AB, Uppsala, Sweden). Prior to routine use, a brief verification of MIRIS was performed (between-run and within-run precision).

Results: In precision study the coefficients of variation were all below 10 %, as well as bias, with the exception of the between-run for crude proteins high control level (bias was 12 %). Storage temperature in the donor's home positively correlated with fat (p=0.004) and energy content (p=0.009) and negatively correlated with carbohydrates (p=0.003). The duration of lactation (p<0.001) and the duration of HM storage (in donor's home p=0.022; in the bank p=0.001; total duration of HM storage p<0.001) negatively correlated with proteins in HM. Statistically significant difference was obtained for all components (fat p=0.008, proteins p=0.006, carbohydrates p<0.001, energy content p=0.002) when comparing infant's sex and milk macronutrients, with male infants having higher values.

Conclusions: This study demonstrates that various factors can affect the macronutrient content of donated HM. It is important to monitor all factors that may impact on the quality of HM.

克罗地亚母乳库中常量营养素含量与捐赠特征的相关性。
目的:母乳中的最佳常量营养素(蛋白质、脂肪、碳水化合物)值对婴儿的健康成长至关重要,特别是那些出生体重很低的婴儿。本研究旨在探讨HM中常量营养素含量与克罗地亚HM银行捐赠特征之间的相关性。方法:从51例献血者中抽取211例HM。HM在MIRIS人乳分析仪(MIRIS AB, Uppsala, Sweden)上进行分析。在常规使用之前,对MIRIS进行了简短的验证(运行间和运行内精度)。结果:精密度研究的变异系数均小于10 %,除粗蛋白质高对照水平的运行间偏差为12 %外,其余均存在偏差。供体家中储存温度与脂肪(p=0.004)和能量含量(p=0.009)呈正相关,与碳水化合物(p=0.003)负相关。结论:本研究表明,多种因素均可影响供体母乳中常量营养素的含量。监控所有可能影响HM质量的因素是很重要的。
