Gastrointestinal dysfunctions as a risk factor for sleep disorders in children with idiopathic autism spectrum disorder: A retrospective cohort study.
Kids with ASD plus GI issues are 70 % more likely to have sleep disorders—so screen the gut when the nights are rough.
01Research in Context
What this study did
The team looked back at medical charts of children with idiopathic autism. They asked: do kids who also have tummy trouble wake up more at night?
They compared sleep records between children with and without GI problems like reflux or constipation.
What they found
Kids with both ASD and GI issues had 1.7 times higher odds of sleep disorders.
In plain words, when a child’s stomach hurts, the night often gets longer for everyone.
How this fits with other research
Paavonen et al. (2008) first showed that over half of kids with Asperger syndrome have big sleep problems. Laposa et al. (2017) now adds a reason—GI pain may be one driver.
Cheng et al. (2021) later found that 67 % of young Chinese children with ASD have sleep trouble. The new GI link gives clinicians a concrete first place to look.
Udhnani et al. (2025) seems to disagree: in autistic adults, anxiety and depression fully explain poor sleep, not autism itself. The clash fades when you see the studies look at different ages and causes—kids’ sleep can be stirred by constipation, adults’ by mood.
Why it matters
Next time a child with ASD keeps waking, ask about reflux, constipation, or diarrhea. Treating the gut—adding fiber, changing diet, or using meds—may cut night waking faster than sleep meds alone. Track both BM logs and sleep logs for one week; you may spot a pattern you can fix.

03Original abstract
Sleep disorders often co-occur with autism spectrum disorder. They further exacerbate autism spectrum disorder symptoms and interfere with children's and parental quality of life. This study examines whether gastrointestinal dysfunctions increase the odds of having sleep disorders in 610 children with idiopathic autism spectrum disorder, aged 2-18 years, from the Autism Genetic Resource Exchange research program. The adjusted odds ratio for sleep disorder among those with gastrointestinal dysfunctions compared to those without was 1.74 (95% confidence interval: 1.22-2.48). In addition, the odds of having multiple sleep disorder symptoms among children with gastrointestinal dysfunctions, adjusted for age, gender, behavioral problems, bed wetting, current and past supplements, and current and past medications for autism spectrum disorder symptoms were 1.75 (95% confidence interval: 1.10-2.79) compared to children without gastrointestinal dysfunctions. Early detection and treatment of gastrointestinal dysfunctions in autism spectrum disorder may be means to reduce prevalence and severity of sleep problems and improve quality of life and developmental outcomes in this population.
