孤独症谱系障碍儿童饮食行为及营养素问题的研究进展

Research progresson abnormal mealtime behavior and micronutrient levels in children with autism spectrum disorders

孤独症谱系障碍(autism spectrum disorder,ASD)的主要核心症状为社交互动障碍,狭隘的兴趣和重复刻板行为,后者常常也表现在饮食行为方面。ASD儿童存在严重的饮食行为问题,易引起摄入的食物种类减少,营养素水平降低,进一步加重ASD儿童的症状。因此,本文就ASD儿童的饮食行为、营养素问题及其干预进行总结和阐述。

The main core symptoms of autism spectrum disorders（ASD）are impaired social interaction and communication,restricted interests and repetitive stereotypical behavior.The last two aspects are usually shown in eating behavior.Compared with typically developing children,autism children have more serious feeding problems.Limited food repertoire may affect the diversity of accepted food,decreasing the micronutrient levels,aggravating symptoms of autistic children.This review will summarize and discuss the abnormal mealtime behavior,micronutrient deficiency and micronutrient intervention.
