Abstract: Children with autism spectrum disorder （ASD） are often complicated with eating disorders，including abnormal eating behavior and other gastrointestinal symptoms. The etiology involves neurobiological，psychosociological and other aspects. Identifying the influencing factors and accurately evaluating them are the basis for intervention，and the current evaluation system needs to be further improved. The intervention of ASD combined with eating disorders is family-centered，supported by behavioral and dietary interventions，and multidisciplinary professional guidance is neededin all aspects and through the whole process of intervention.
