Comparing sleep patterns between children with autism spectrum disorder and children with typical development: A matched case-control study.

Tse et al. (2020) paired each autistic child with a typically developing kid of the same age and sex. They used wrist-watch actigraphy to record four sleep numbers for both groups over several nights.

The study ran a matched case-control design. No one got an intervention; the goal was to see if the groups slept differently.

Autistic children slept worse on every count. They got less total sleep, took longer to fall asleep, woke up more often, and had lower sleep efficiency.

The differences were large enough to show up in the actigraphy data night after night.

Tyagi et al. (2019) asked parents in India the same question and got the same answer: autistic kids sleep worse. Their survey added that kids with more hyperactivity or sensory issues had the most trouble.

Sosnowski et al. (2022) stretched the finding across cultures. Saudi autistic children fell asleep even slower, while UK autistic children reported more night fears. The basic gap holds no matter where families live.

Morrison et al. (2017) looked at the same kids one year later. Parents said sleep problems eased as anxiety dropped, but the actigraphy numbers stayed poor. The new study confirms that parent relief does not equal fixed sleep.

Poor sleep is not a side note; it is part of the autism profile. Screen with actigraphy or simple sleep diaries, then treat early. Options already tested include low-dose melatonin (Barry et al., 2011) and brief parent sleep plans built from an FBA (McLay et al., 2019). Better nights improve daytime learning and lower family stress.
