摘　　要：目的对兰州地区乳母乳汁供能物质(蛋白质、脂肪、乳糖)与常量微量元素(钙、铜、铁、锌、镁、钠、钾)状况进行分析,并调查本群体乳汁供能物质及常量微量元素上存在的问题,为指导母乳喂养提供依据。方法①将优选收集到的兰州地区1 215例纯母乳喂养、婴儿生长发育良好的乳母乳汁,进行蛋白质、脂肪、乳糖、钙、铜、铁、锌、镁、钠、钾含量的测定,采用正态分布法计算本群体纯母乳喂养的乳汁适宜参考范围;②以本地区大群体乳汁结果与研究所得适宜范围、国内其他地区乳汁进行比较,分析本地区群体乳汁与其他地区结构上的差异。结果本群体纯母乳喂养率达48.5%;纯母乳喂养,婴儿发育良好的优质组脂肪、乳糖、蛋白质80%正常值范围分别为(单位:g/100 g):1.57~5.11、6.58~7.16、0.79~1.35;钙、铜、铁、锌、镁、钠、钾的80%正常值范围分别为:5.25~7.83 mmol/L、5.66~8.28 mmol/L、0.14~0.3 mmol/L 、15~64.48 μmol/L、0.98~1.62 mmol/L、1.92~18.82 mmol/L、7.95~17.31 mmol/L;优质组适宜范围与国内其他地区正常值比较,蛋白质、脂肪、乳糖含量偏低。本群体大范围检测,乳汁蛋白质、脂肪、乳糖、热量、钙、铜、锌、钠含量明显低于优质纯母乳喂养组适宜范围(P<0.01)。结论本群体乳母乳汁质量欠佳,应通过适当的方式,使母乳中各种成分含量更趋合理,更利于婴儿的生长发育。Objective To analyze the energy supply nutrients (protein, fat and lactose) and mineral elements (calcium, copper, iron, zinc, magnesium, sodium, potassium) supplied in breast milk from the resident of Lanzhou, and investigate the problems of those energy supply nutrients and mineral elements in breast milk of this population so that to provide basis for breast feeding. Methods Breast milk from 1 215 mothers whose babies were fed totally by the breast milk and grew well was collected and assayed for the contents of protein, fat, lactose, calcium, copper, iron, zinc, magnesium, sodium and potassium in Lanzhou region. The optimal range for breast feeding was set by normal distribution method. The results were compared with the breast milk from other internal region in order to clarify the contents difference. Results The prevalence of mother-milk-fed in this region was 48.5%. The normal ranges (unit: g/100 g) of fat, lactose and protein were 1.57-5.11, 6.58-7.16 and 0.79-1.35, and the normal ranges of calcium, copper, iron, zinc, magnesium, sodium and potassium were 5.25-7.83 mmol/L, 5.66-8.28 mmol/L, 0.14-0.3 mmol/L, 15-64.48 μmol/L, 0.98-1.62 mmol/L, 1.92-18.82 mmol/L, 7.95~17.31 mmol/L in the high quality breast milk. Compared with the other internal region, the normal ranges of the protein, fat and lactose in Lanzhou were lower. The contents of protein, fat, lactose, calories, calcium, copper, zinc and sodium in the breast milk from the whole investigated population were significantly lower compared with breast milk of high quality (P<0.01). Conclusion The quality of breast milk in Lanzhou is not so good. The contents of various nutrients in breast milk should be improved to a proper level by appropriate ways so that to improve the growth and development of the baby.
