摘要
目的:了解江门市新会区乳母成熟乳主要营养成分的含量与不同年龄、产次、分娩方式的差异。方法:收集江门市新会区1 250例孕足月产后42天乳母的乳汁20 ml,检测标本中的主要营养成分蛋白质、脂肪、乳糖的含量、并与参考值标准进行比较,统计其达到参考值的百分比;统计分析不同年龄段、分娩方式、产次乳母的成熟乳主要营养成分的差异。结果:新会区乳母成熟乳中乳糖、蛋白质含量稳定,均达到或高于参考值;脂肪含量不稳定,34.7%达参考值,3.6%高于参考值,61.8%低于参考值;20～29、30～34及≥35岁3个年龄段和初产妇与经产妇、顺产及剖宫产乳母乳汁主要营养成分差异无统计学意义(P>0.05)。结论:新会区乳母营养状况总体良好,但乳汁中脂肪的含量不稳定,低于参考值的比例较大,应广泛开展针对乳母的膳食营养指导,进一步改善乳母乳汁质量;新会区产妇成熟乳主要营养成分不受乳母年龄、产次、分娩方式的影响,提倡所有健康产妇产后坚持哺乳4～6个月以上。
