Study Ties Maternal Military, Judicial Work to 59% Higher Autism Risk in 110,234-Participant Denmark Analysis

Military or defence jobs and judicial-sector work were each linked to 59% higher odds of a child being diagnosed with autism spectrum disorder, according to a Danish study of 110,234 participants.
Ground transportation work was associated with a 24% increase, and researchers said the pattern points to possible effects from toxicants, combustion products and high job stress before conception and during pregnancy.
The analysis covered 1,702 autism cases and 108,532 matched controls born between 1973 and 2012, using mothers’ employment records and adjusting for factors including age, smoking, socioeconomic status and neuropsychiatric history.
Agriculture showed no autism link despite possible pesticide exposure, while associations generally weakened during infancy, suggesting the preconception and pregnancy periods may matter more.
Because the study was observational and based on broad industry categories in Denmark rather than specific tasks or exposures, the authors said it cannot prove causation and called for more targeted exposure research.
Are studies linking jobs to autism risk unfairly reviving the history of blaming mothers?
Do certain jobs cause autism in children, or do they simply attract autistic parents?
Maternal Occupations and Autism Risk: Insights from a 110,000-Pair Danish Study (1973–2012)
Overview
A major Danish study published in May 2026 analyzed registry data from over 110,000 mother-child pairs to explore whether a mother's job history is linked to autism risk in her children. The researchers identified 1,702 children with autism and compared them to over 108,000 children without autism, matched by sex and birth year. The study found that mothers working in certain fields—such as military or defense, ground transportation, and public administration—were more likely to have a child diagnosed with autism. These findings highlight possible occupational influences on autism risk, though the study cannot prove cause and effect.
