Systematic Reviews on Eating Disorders and Autism Spectrum Disorder Emphasize a Call to Further Expand High-Quality Research.

Two recent systematic reviews provide important insights into the current state of the eating disorder literature regarding autistic traits, ASD prevalence, and experience with accessing treatment, with a specific focus on anorexia nervosa (AN). The extant literature provides converging evidence for elevated autistic traits in individuals with AN, while evidence for increased prevalence of ASD in AN is less robust. Presence of autistic traits or a formal ASD diagnosis both appear to elevate the potential for a more complicated experience during eating disorder treatment. Together, this work provides compelling justification to expand the breadth of inquiry regarding eating disorders and ASD, with a specific call for increased methodological rigor when designing and conducting future research. My commentary calls for specific steps to advance our understanding of ASD and eating disorders.
