Predictors of sleep quality for autistic people across adulthood.
Poor physical health and anxiety—not age—drive sleep problems in autistic adults.
01Research in Context
What this study did
The team sent an online survey to 730 autistic adults. They asked about sleep, health, anxiety, and basic facts like age and sex.
No one got an intervention. The goal was to see which factors best predict poor sleep in autistic adults.
What they found
Three things stood out: poor physical health, being assigned female at birth, and high self-reported anxiety. These predicted worse sleep quality. Age itself did not matter much.
How this fits with other research
Greene et al. (2019) already showed that sleep problems lower quality of life in autistic adults. The new study flips the question: what causes the sleep problems in the first place?
Vassos et al. (2023) looked at preschoolers and found self-injury and sensory issues forecast later sleep trouble. That seems opposite, but it is about kids, not grown-ups. Different life stages, different drivers.
Ferraiolo et al. (2026) zoomed in on 18-35-year-olds and linked poor sleep efficiency to higher depression. Together the papers draw a line: bad sleep hurts adults, and anxiety plus health issues feed the cycle.
Why it matters
When an autistic adult complains of tiredness, check for untreated pain, illness, or anxiety before blaming age. A quick health screen and anxiety measure can guide your next step, whether a doctor visit or a relaxation plan. Better sleep means better days.

03Original abstract
Poor sleep can have a significant impact on physical health and well-being. Sleep problems are common among autistic children, but less is known about sleep across the autistic adult lifespan. Autistic adults (n = 730, aged 18-78 years) were recruited via Simons Powering Autism Research for Knowledge Research Match. Participants completed online surveys asking about demographics, health problems, social support, symptoms of anxiety and depression, and overall and specific aspects of sleep quality. Regression analyses explored the variables associated with sleep quality. Physical health, assigned female sex at birth and self-reported anxiety symptoms significantly contributed to models for all aspects of sleep. Perceived stress contributed to models of overall and subjective sleep quality, and daytime dysfunction. Depression symptoms did not contribute significantly to any of the models of sleep quality. However, utilizing government support mechanisms (such as social security) contributed to the model of sleep efficiency. Age contributed little to models of sleep quality, whereas perceived stress and psychotropic medication use contributed to some but not all aspects of sleep. Sleep quality is poor for autistic people across the adult lifespan. Given known impacts of poor sleep on health, cognition and quality of life, attention should be paid to sleep and its possible everyday effects for autistic people of all ages.
