Combinations of physical activity, sedentary behaviour and sleep: relationships with health indicators in school-aged children and youth
Open accessAbstract
The purpose of this systematic review was to determine how combinations of physical activity (PA), sedentary behaviour (SB), and sleep were associated with important health indicators in children and youth aged 5–17 years. Online databases (MEDLINE, EMBASE, SPORTdiscus, CINAHL, and PsycINFO) were searched for relevant studies examining the relationship between time spent engaging in different combinations of PA, SB, and sleep with the following health indicators: adiposity, cardiometabolic biomarkers, physical fitness, emotional regulation/psychological distress, behavioural conduct/pro-social behaviour, cognition, quality of life/well-being, injuries, bone density, motor skill development, and self-esteem. PA had to be objectively measured, while sleep and SB could be objectively or subjectively measured. The quality of research evidence and risk of bias for each health indicator and for each individual study was assessed using the Grading of Recommendations Assessment, Development, and Evaluation (GRADE) framework. A total of 13 cross-sectional studies and a single prospective cohort study reporting data from 36 560 individual participants met the inclusion criteria. Children and youth with a combination of high PA/high sleep/low SB had more desirable measures of adiposity and cardiometabolic health compared with those with a combination of low PA/low sleep/high SB. Health benefits were also observed for those with a combination of high PA/high sleep (cardiometabolic health and adiposity) or high PA/low SB (cardiometabolic health, adiposity and fitness), compared with low PA/low sleep or low PA/high SB. Of the 3 movement behaviours, PA (especially moderate- to vigorous-intensity PA) was most consistently associated with desirable health indicators. Given the lack of randomized trials, the overall quality of the available evidence was low.

The paper relies on this without support.
The evidence on combinations of movement behaviours has yet to be systematically reviewed or synthesized.
“Researchers have recently begun to compare the health impacts of specific combinations of these movement behaviours, but this evidence has yet to be systematically reviewed or synthesized.”
The paper relies on this without support.
Meta-analysis was not possible because of high levels of heterogeneity across studies.
“However, it was determined that a meta-analysis was not possible because of high levels of heterogeneity for the above characteristics across studies, and a narrative synthesis was performed for each health indicator instead.”
The paper relies on this without support.
Subjective measures of PA typically focus exclusively on moderate-to-vigorous-intensity PA (MVPA).
“whereas subjective measures of PA typically focus exclusively on moderate-to vigorous-intensity PA (MVPA).”
The paper relies on this without support.
The minimum sample size thresholds of 300 for observational studies and 30 for intervention studies are appropriate.
“Observational studies (e.g., cross-sectional, prospective or retrospective cohorts, and case-control studies) were required to have a minimum sample size of 300 participants; randomized controlled trials and other intervention studies were required to have at least 30 participants in the intervention group.”
The paper relies on this without support.
Combinations of physical activity, sedentary behaviour, and sleep can be meaningfully classified into high/low categories to examine associations with health indicators.
“the majority of studies compared only the best and worst combinations of behaviours (e.g., high PA/high sleep/low SB vs low PA/low sleep/high SB)”

About these checks
Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.
A language model drew the claims from the paper on 2026-10-10, under version 3 of the claim definition (model deepseek-v4.1-flash, prompt extract-v3).
A second model labelled each claim on 2026-10-10 (model jev-1.13-20260917, definition revision gold-guideline-v0.2).
Statistics and arithmetic are recomputed, not judged.
Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
