二十二碳六烯酸与认知功能发育研究进展

Research advances on docosahexaenoic acid and cognition function deveolpment

二十二碳六烯酸(DHA)参与机体的多种生理功能,对生命早期大脑发育、机体的认知功能发育、视觉发育以及机体免疫功能具有重要作用。本文从DHA的来源及其对认知功能的作用进行综述,发现DHA对婴幼儿,特别是早产儿的大脑发育、认知功能发育、精神运动发育有积极作用。但随着年龄增加,对学龄儿童智力上的影响差异并无统计学意义。孕乳母及婴幼儿适量DHA的摄入对生命周期内大脑DHA水平的维持至关重要。

Docosahexaenoic acid(DHA)is a long-chain polyunsaturated fatty acid(LCPUFA)that has involved in various functions of life.It plays an important role in brain development,cognitive function and visual development,as well as the immune function of newborns.This article reviews the origins of DHA and its effects on cognitive function,and explores the effects of DHA intake on the development of cognitive function in preterm infants,infants and childhood.However,with the increase of age,there is no significant difference in the influence on the intelligence of school-age children.Appropriate DHA intake of pregnant,lactating mothers and infants is very important for the maintenance of brain DHA level in life cycle.
