    [摘要] 母乳中含有多种对婴幼儿大脑发育起着重要作用的营养物质，这些营养物质对婴幼儿神经心理发育有促进作用，加强母乳喂养优越性及相关机制的研究是保证母乳喂养目标实现的重要基础。本文通过查阅文献，阐述了母乳中二十二碳六烯酸(DHA)和胆固醇等脂类分子的营养及体内皮质醇水平对婴幼儿神经心理发育的影响机理，旨在通过研究DHA、胆固醇营养和皮质醇水平协同促进母乳喂养婴幼儿语言和行为发育的机理，为母乳喂养促进婴幼儿神经心理发育提供新的思路和实证依据。

    [Abstract] Breast milk contains a variety of nutrients that plays an important role in the development of infants' brain， these nutrients would promote the infants' neuropsychological development. The research on strengthening breastfeeding superiority and related mechanism is an important foundation that guarantee to achieve the goal of breastfeeding. Though literature review， this paper shows the influence mechanism of infants' neuropsychological development by docosahexaenoic acid (DHA)， cholesterol nutrition and other lipid molecules in the breast milk， and the cortisol level. It aims to provide new ideas and empirical evidence for breastfeeding to promote infants' neuropsychology development through studying DHA， cholesterol nutrition and cortisol level synergistically promote the development mechanism of breastfeeding of infants' language and behavior development. ......
