Study Links Adverse Childhood Experiences to Autism Spectrum Disorder Identification in Late Adolescents
Research Overview
A recent retrospective cohort study has explored the relationship between adverse childhood experiences (ACEs) and the identification of autism spectrum disorder (ASD) among late adolescents serving in the Israel Defense Forces (IDF). The study analyzed data from over 288,000 conscripts evaluated between 2009 and 2021, aiming to understand how early-life adversity might relate to ASD diagnosis during military service.
The original study was published online ahead of print in the International Journal of Psychiatry in Clinical Practice on October 5, 2026.
Key Findings
At the time of enlistment, 935 individuals (0.33%) had an ASD diagnosis, while an additional 635 were identified with ASD during their military service. The majority of those diagnosed were male (90.1%), Jewish (97.9%), Israeli-born (91.4%), and came from higher socioeconomic backgrounds. Notably, a substantial portion had at least 12 years of education and higher IQ scores compared to their peers.
The study found that several types of ACEs—including emotional and verbal abuse, physical abuse, neglect, parental substance use, and parental incarceration—were significantly associated with ASD identification during service. Importantly, individuals with two or more ACEs had more than double the odds (odds ratio 2.27) of being diagnosed with ASD during their military tenure.
Context and Implications
These findings suggest that early adverse experiences may play a role in the later identification of ASD, potentially by influencing the manifestation or recognition of symptoms during late adolescence. The researchers propose that incorporating ACE screening into military enlistment evaluations could improve early detection of ASD and enable timely clinical support for affected individuals.
Considerations and Limitations
While the study highlights an association between ACEs and ASD identification, it does not establish a direct cause-and-effect relationship. The data are based on retrospective reports and military medical evaluations, which may have inherent limitations. Additionally, the population studied is specific to Israeli military conscripts, which may affect the generalizability of the findings to other groups.
Conclusion
This research contributes to a growing understanding of how childhood adversity may relate to neurodevelopmental diagnoses in adolescence and early adulthood. Families and healthcare providers might consider the potential impact of early-life stressors when supporting individuals with ASD or those undergoing late diagnosis.
