摘要

评估母乳的营养成分对于了解母乳作为婴儿唯一营养来源的充足性非常重要。本研究旨在分析不同社会经济状况的足月和早产HBM的近似组成以及总氨基酸和脂肪酸谱。这项横断面研究包括120名来自特伦甘纳海得拉巴妇产医院的足月或早产哺乳期母亲。在产后第一周内从每位参与者那里收集的母乳中估计了营养接近、总氨基酸和脂肪酸概况。足月时的常量营养成分与早产母乳相似。与足月(8.61±0.23)相比,早产儿的必需氨基酸亮氨酸显著升高(8.91±0.18)。ω-5脂肪酸肉豆蔻酸与足月(0.11±0.02)相比显著升高,而ω-6脂肪酸,如二十二碳二烯酸和二十碳二烯酸,在足月与早产相比显著升高。此外,还发现单不饱和脂肪酸和ω-9脂肪酸在下层社会经济群体中显著较高,而多不饱和脂肪酸酯和ω-3和6脂肪酸在上层社会经济群体显著较高。本研究得出结论,母乳的营养成分,如必需氨基酸和脂肪酸,在不同胎龄和社会经济群体中差异很大。

Macronutrient composition of term and preterm human milk of different socio economic groups

Assessment of the nutritional composition of Human Breast Milk (HBM) is important to understand its sufficiency as the sole nutrient source in infants. The present study is aimed to analyze the proximate composition along with total amino acid and fatty acid profile in term and preterm HBM of different socio economic status.

This cross sectional study included, 120 lactating mothers with term or preterm gestation from maternity hospitals located in Hyderabad, Telangana. Nutritional proximate, total amino and fatty acid profiles were estimated in pooled human milk collected from each participant within the first week of postpartum.

The macronutrient composition in term was similar to that of preterm breast milk. The essential amino acid Leucine was significantly high in preterm (8.91 ± 0.18) when compared to term (8.61 ± 0.23). ω-5 fatty acid Myristoleic acid was significantly high in preterm (0.14 ± 0.02) when compared to term (0.11 ± 0.02), whereas ω-6 fatty acids like Docosadienoic Acid and Eicosadienoic acid were found to be significantly high in term when compared to preterm. Further, it was also found that the mono unsaturated and ω-9 fatty acids were significantly high in lower socio economic group, whereas, poly unsaturated and ω -3 and 6 fatty acids were significantly high in upper socio economic group.

The present study concludes that, nutritional composition like essential amino and fatty acids of human milk vary significantly between different gestational age as well as in socio economic groups.
