24-hour movement behaviors of physical activity, screen time, and sleep in youth with down syndrome compared to typically developing peers.
Article in Acta psychologica, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
backgroundYouth with Down syndrome (DS) tend to have a higher prevalence of obesity compared to their peers with typical development (TD). Physical activity, sleep and screen time are modifiable behaviors which can influence childhood obesity. To better understand an individual's activity, these behaviors should be examined concurrently versus independently over a 24-h period.
objectiveTo pilot the examination and comparison of physical activity, sleep, and screen and non-screen sedentary behaviors concurrently in a 24-h period, and determine if 24-h guidelines were met in a sample of youth with DS and peers with TD.
methodsThis secondary data-analysis from a cross-sectional study included youth with DS and peers with TD. Parent reported 24-h activity logs were completed for 6 days. Total minutes spent in each behavior were calculated and the 24-h movement guideline recommendations were compared between groups using independent t-tests and chi-square analyses.
resultsYouth with DS (n = 8) and youth with TD (n = 9) spent significantly different time in moderate-to-vigorous physical activity (t(15) = 2.334, p = 0.034). Light physical activity, non-screen and screen time sedentary behaviors, and sleep were comparable. Both groups met recommended guidelines for moderate-to-vigorous activity and sleep, however, screen time guidelines were only met by 50% of youth with DS and 22% of youth with TD.
conclusionsYouth with DS met two of the three recommended guidelines for the 24-h movement behaviors. By studying each behavior concurrently over a 24-h period, an increased understanding of activity is present and targeted changes can be made.
