Physical Health of Autistic Girls and Women: A Scoping Review

Background: There is a growing recognition of sex and gender influences in autism. Increasingly, studies include comparisons between sexes or genders, but few have focused on clarifying the characteristics of autistic girls' and women's physical health. Methods: A scoping review was conducted to determine what is currently known about the physical health of autistic girls and women. We screened 1,112 unique articles, with 40 studies meeting the inclusion criteria. We used a convergent iterative process to synthesize this content into broad thematic areas. Results: Overall, autistic girls and women experience more physical health challenges compared to non-autistic girls and women, and to autistic boys and men. Preliminary evidence suggests increased neurological conditions (e.g., epilepsy) in autistic girls and women compared to autistic boys and men. As well, the literature suggests increased endocrine/reproductive conditions in autistic girls and women compared to non-autistic girls and women. Limitations: The literature has substantial heterogeneity in how physical health conditions were assessed and reported. Further, our explicit focus on physical health may have constrained the ability to examine potential interactions between mental and physical health. In addition, the widely differing research aims and methodologies make it difficult to reach definitive conclusions. Nevertheless, in keeping with the goals of a scoping review, we were able to identify key themes to guide future research. Conclusions: Emerging themes in the literature suggest that autistic girls and women have heightened rates of physical health challenges compared to autistic boys and men, and non-autistic girls and women. Clinicians should seek to provide holistic care for this population that includes a focus on physical health and recognizes that autistic girls and women have co-occurring conditions that differ from those of autistic boys and men.
