渭南市4317例母乳成分检测结果分析

Analysis of the detection results of 4 317 cases of breast milk composition in Weinan city

目的对渭南市成熟母乳成分进行分析,为指导本地区母乳喂养工作提供依据。方法收集正常乳母分泌的成熟乳汁样本,使用"MIRIS HMA型母乳分析仪",检测其中宏量营养素含量,分析结果及其相关影响因素。结果渭南市4 317例乳母的成熟母乳中脂肪、蛋白质、糖类、干物质、能量是动态变化的,婴儿月龄增加时,对应的母乳各营养成分也随之而变化。其中:脂肪和干物质有所减少,但不显著(P>0.05),蛋白质和能量均明显减低,按月龄比较差异有统计学意义(P<0.05),糖类有所增加,但按月龄比较差异无统计学意义(P>0.05)。结论母乳中的各营养成分是动态变化的,乳汁成分高低与乳母年龄、乳儿性别关系不明显,本地区成熟乳所含宏量营养素中,除糖类外,蛋白质、脂肪、能量含量均较国内外高。

Objective To analyze the mature breast milk composition in Weinan City,and to provide the basis for guiding the work of breastfeeding in this region. Method Healthy lactating women mature breast milk samples were collected using the MIRIS HMA Milk Analyzer＂,to detect the macro nutrient content and analyze results and the related factors. Results The subject included 4 317 samples,the composition of fat,proteins,carbohydrates,drymatter,energy were dynamic.The nutritional components of the milk also changed by baby months increasing.The fat and dry matter decreased but the changes were not significantly（P0.05）,proteins and energy were decreased significantly by the month of age（P0.05）.Carbohydrate was increased,but differences were not significant by the month of age（P0.05）. ConclusionsThe nutrients in breast milk were dynamic changed,relationships of milk composition level and maternal age,infant sex were not obvious,macro nutrient elements in local district mature milk contains,protein,fat,energy content except carbohydrate were higher than results of domestic and foreign areas.
