The search period was from the establishment of the database to March 31th, 2023. The quality of the guide was independently evaluated by 4 researchers, and the remaining articles were evaluated by 2 researchers. Content extraction, evidence integration and grading of the included articles were carried out, and the level of evidence recommendation was formed through the expert meeting.Results:A total of 19 articles were included, including 3 guidelines, 1 expert consensus, 13 systematic reviews and 2 randomized controlled trials. This paper summarized 25 best evidence from 5 aspects, including the common eating behavior problems of children with autism, the assessment of eating behavior problems, causes, consequences and intervention methods.Conclusions:The best evidence summarized in this study provides a basis for the management of eating behavior problems in children with autism. It is suggested that clinical staff should fully consider the clinical context when applying the evidence, and formulate more detailed and feasible eating behavior intervention programs combined with the children and their families.
