Objective To study the concentrations of Ca,Zn,Cu,Fe and Mn in breast milk of the lactating mother in Sanjiang of Guangxi.Methods Breast milk samples were collected from 120 lactating mothers in Sanjiang.Ca,Zn,Cu,Fe and Mn in human milk were measured.Dietary composition of the enrolled lactating mothers was investigated.Results The Dong lactating mothers'daily intakes of Fe were notable higher than that of the DRIS standard(P 0.05),while Ca and Zn were lower than those of the standard,respectively(P 0.01) .In the first month,the milk Fe of the lactating mothers in Sanjiang was higher than those of the reference value;And in the following months,the milk Ca,Zn and Fe were generally lower than those of the reference value.Conclusion Efforts should be made to enhance the nutrition education among the local women during lactation period.We suggest that pregnant and lactating women in Sanjiang should increase their intake of Ca,Zn and Fe.

目的 了解广西三江县侗族乳母的膳食营养及乳汁营养素的状况.方法 收集广西三江县侗族120名0～6月乳母的乳汁,测定其蛋白质、脂肪、碳水化合物、钙、铁、锌、维生素A的含量,并对产妇进行膳食调查.结果 乳母产后1个月内蔬菜、豆类等摄入严重不足,产后1个月以后优质蛋白质摄入不足.满月前乳母乳汁中蛋白质、脂肪、铁的含量高于参考值,满月后蛋白质、铁的含量低于参考值.钙、锌、维生素A的含量低于参考值.碳水化合物的含量接近参考值.结论 应加强对少数民族农村地区乳母的营养指导,改变哺乳期不均衡的膳食习惯.建议广两i江侗族孕妇及乳母应适当增加铁、锌和优质蛋白质的摄取量.

目的:了解广西三江县侗族、南宁市汉族乳母膳食营养状况及乳汁中各种营养素的含量。方法:收集240名广西三江县侗族和南宁市汉族乳母产后0~6个月的乳汁,测定其蛋白质(PRO)、脂肪(FAT)、碳水化合物(COH)、钙(Ca)、锰(Mn)、铁(Fe)、铜(Cu)、锌(Zn)、维生维A(VitA)的含量,并对乳母进行膳食调查。结果:①膳食调查结果:侗、汉族乳母膳食结构明显不同。侗族乳母PRO、COH、Fe每日平均摄入量均显著高于DRIS标准(P<0.05);Ca、Zn及VitA平均摄入量均低于DRIS标准(P<0.01)。汉族乳母PRO、COH每日平均摄入量高于DRIS标准(P<0.01);Ca、Zn、Fe及VitA每日平均摄入量均低于DRIS标准(P<0.01)。侗族乳母膳食PRO、COH、Ca、Mn、Cu摄入量均明显低于汉族乳母(P<0.01);②母乳各营养素含量分析结果:侗族满月前母乳PRO、FAT、Fe含量高于参考值,满月后Ca、Fe、Zn、VitA含量低于参考值。汉族满月前后母乳PRO和FAT含量高于参考值,Ca和VitA低于参考值;满月后Mn和Cu含量高于参考值,Fe、Zn和VitA含量低于正常值。侗族母乳PRO、FAT、Ca、Mn、Cu、Zn含量均显著低于汉族母乳(P<0.05)。结论:广西三江县侗族、南宁市汉族乳母膳食Ca、Zn、VitA人均每日摄入量均较DRIS标准明显偏低;侗、汉族母乳Ca、Zn、VitA含量均较参考值偏低。
