PMID 40246747WHAT IT FOUND
Autistic children rarely meet health guidelines, especially for screen time and sleep.
Physical activity rates matched peers when measured as daily activity, but autistic children were less likely to be active four or more days a week. Irregular bedtime linked to poorer outcomes.
Key findings
01Autistic children had a lower prevalence of meeting screen time guidelines in all age groups and lower prevalence of meeting sleep guidelines in those 3–5 and 6–11 years, though the sleep difference for 6–11 years became non-significant after adjustment.
02While the prevalence of meeting daily physical activity guidelines was low in both groups without significant differences, a sensitivity analysis showed autistic children were less likely to participate in physical activity four or more days per week.
03Among autistic children, having an irregular bedtime was associated with a lower prevalence of meeting physical activity and sleep guidelines, while low household income was associated with a higher prevalence of meeting physical activity guidelines.

What it does not show
All data was parent-reported, which may overestimate physical activity and sleep and underestimate screen time. Physical activity questions did not capture intensity, so autistic children may report similar durations but engage in less vigorous activity. The cross-sectional design shows association but cannot prove that irregular bedtime or income causes these behavioral outcomes. Medical comorbidities like obesity or sleep apnea were not controlled for, so it is unclear how much they drive the disparities.
Declared interests
The authors declare no potential conflicts of interest.
The easy way to misread this
Do not conclude that autistic children have similar physical activity levels to peers. While daily activity rates were similar, autistic children were significantly less likely to be active four or more days per week, and the survey did not measure activity intensity.
