Moving Beyond the Phenotypic Correlation Between Anorexia Nervosa and Autism.

The recent systematic review and meta-analysis by Inal-Kaleli et al. is situated within a growing area of research, investigating the relationship between anorexia nervosa and autistic characteristics. Their synthesis of research within the topic finds support for elevated autistic characteristics and autism in individuals with anorexia nervosa and a small but significant correlation between autistic traits and level of eating disorder symptoms. In this commentary, we discuss the findings of Inal-Kaleli and colleagues and propose further research to generate insights into the nature of this link. We focus on the potential origins of the observed relationship, specific mechanisms, and manifestation of anorexia nervosa in autistic populations, and the influence of sex and gender on the intersection of eating disorders and autism. By addressing these largely unexplored research avenues, future investigations can go beyond the phenotypic correlations and facilitate the development of prevention and intervention suited for individuals experiencing both disordered eating and elevated autistic traits.
