Key Takeaway
Note elevated risks for multiple outcomes in autistic people across 134 reviews; evidence strength varied.
This umbrella review synthesizes findings from 134 existing reviews to examine a wide array of outcomes in autistic people. The scope includes mental health, physical health, social functioning, and mortality indicators. The authors do not describe a specific study population or intervention because this is a review of reviews rather than a primary trial. Instead, the text aggregates qualitative conclusions from the underlying literature.
The analysis indicates elevated risks for anxiety and mood disorders, suicidality and self-harm, eating and psychotic disorders, sleep problems, epilepsy, gastrointestinal and feeding difficulties, obesity, oral health problems, increased mortality risk, victimisation and bullying, reduced quality of life, loneliness, relationship difficulties, and unemployment. Effect sizes and absolute numbers were not reported for these outcomes. P-values or confidence intervals were not reported either.
The authors note that evidence strength varied across outcomes. This variation limits the ability to draw firm conclusions about the magnitude of risk for any single condition. The review does not report adverse events, serious adverse events, discontinuations, or tolerability data. Causality was not reported, and funding or conflicts of interest were not reported.
The practice relevance of this work highlights research, clinical practice, and service planning priorities. Clinicians should interpret these findings as associations observed across multiple independent reviews rather than direct causal links. The review underscores the need for comprehensive care addressing these diverse health and social challenges in autistic populations.

BackgroundAutistic people experience an increased risk of a wide range of adverse outcomes across many domains, impacting all aspects of daily life. While individual reviews have explored specific outcome areas, a comprehensive cross-domain synthesis is lacking. Because the evidence spans diverse outcome types and review designs, a narrative umbrella synthesis is needed to integrate findings across heterogeneous reviews and provide a broader systems-level overview.MethodsThis umbrella review identified and synthesised published systematic, meta-analytic, and narrative reviews on the outcomes associated with autism. Five databases were searched from inception to June 2024. Dual screening and multi-reviewer data extraction were conducted, and methodological quality was appraised using established review tools. Findings were aggregated using inductive narrative synthesis, with domain grouping and thematic classification determined by consensus among reviewers.ResultsOf 13,841 records identified, 134 reviews met inclusion criteria. Outcomes were grouped into three organisational domains: mental health, physical health, and social and lifestyle. The most consistently reported adverse outcomes included anxiety and mood disorders, suicidality and self-harm, eating and psychotic disorders, sleep problems, epilepsy, gastrointestinal and feeding difficulties, obesity, oral health problems, increased mortality risk, victimisation and bullying, reduced quality of life, loneliness, relationship difficulties, and unemployment. Evidence strength varied across outcomes, but elevated risk patterns were reported across multiple independent reviews.DiscussionAdverse outcomes for autistic people affect multiple areas of life. This umbrella synthesis identifies the principal outcome clusters supported by review-level evidence and highlights research, clinical practice, and service planning priorities.Systematic Review Registrationhttps://www.crd.york.ac.uk/prospero/, identifier CRD42023475389.
