Abstract
Aims: The present review aimed to synthesize previous research to understand the current prevalence rate of autism across eating disorder (ED) populations. We aim to determine whether the prevalence estimates differ according to type of eating disorder and method of autism diagnosis. / Methods: A systematic search of PsycInfo, MedLine, EMBASE, AMED, CINAHL Plus and Web of Science was undertaken in line with PRISMA-P protocol (see appendix 1). Identified studies were entered into a meta-analysis and pooled prevalence rates were calculated. Sub-group analyses were conducted on type of eating disorder, method of autism diagnosis and age of participants. / Results: A total of 24 papers met eligibility criteria and were included in the review and metaanalysis. The majority of studies were conducted within anorexia nervosa (AN), with femaleidentifying participants, and using the Autism Quotient (AQ) or Autism Diagnostic Observation Scale (ADOS) to identify autism. The pooled prevalence estimate of autism across all ED types was 22%. Studies using the ADOS and the AQ produced similar prevalence estimates and there was an over-representation of autism particularly in AN, with a prevalence estimate of 18%. / Conclusion: Analyzed studies suggest that autism is over-represented in ED populations and the AQ and ADOS produce similar prevalence estimates. Further research should focus on the link between other EDs which co-occur with autism outside of AN, such as Avoidant Restrictive Food Intake Disorder (ARFID), and should include a wider age and gender range.
