Abstract

BACKGROUND: The Canadian 24-h movement guidelines were developed with the hope of improving health and future health outcomes in children and youth. The purpose of this study was to evaluate adherence to the 3 recommendations most strongly associated with health outcomes in new 24-h movement guidelines and their relationship with adiposity (obesity and body mass index z-score) across countries participating in the International Study of Childhood Obesity, Lifestyle and the Environment (ISCOLE). METHODS: ) was calculated, and BMI z-scores were computed using age- and sex-specific reference data from the World Health Organization. Obesity was defined as a BMI z-score > +2 SD. Meeting the overall 24-h movement guidelines was defined as: 9 to 11 h/night of sleep, ≤2 h/day of screen time, and at least 60 min/day of MVPA. Age, sex, highest parental education and unhealthy diet pattern score were included as covariates in statistical models. Associations between meeting vs. not meeting each single recommendation (and combinations) with obesity were assessed with odds ratios calculated using generalized linear mixed models. A linear mixed model was used to examine the differences in BMI z-scores between children meeting vs. not meeting the different combinations of recommendations. RESULTS: The global prevalence of children meeting the overall recommendations (all three behaviors) was 7%, with children from Australia and Canada showing the highest adherence (15%). Children meeting the three recommendations had lower odds ratios for obesity compared to those meeting none of the recommendations (OR = 0.28, 95% CI 0.18-0.45). Compared to not meeting the 24-h movement recommendations either independently or combined, meeting them was significantly associated with a lower BMI z-score. Whenever the MVPA recommendation was included in the analysis the odds ratios for obesity were lower. CONCLUSIONS: For ISCOLE participants meeting these 3 healthy movement recommendations the odds ratios of being obese or having high BMI z-scores were lower. However, only a small percentage of children met all recommendations. Future efforts should aim to find promising ways to increase daily physical activity, reduce screen time, and ensure an adequate night's sleep in children. TRIAL REGISTRATION: The International Study of Childhood Obesity, Lifestyle and the Environment (ISCOLE) was registered at ClinicalTrials.gov (Identifier NCT01722500) (October 29, 2012).

TL;DR

In 6,128 children aged 9–11 years from 12 ISCOLE countries, only 7.2% met all three 24-hour movement guidelines (MVPA, screen time, sleep), and meeting all three was associated with lower odds of obesity (OR 0.28, 95% CI 0.18–0.45) and lower BMI z-score. MVPA was the single recommendation most strongly associated with lower obesity odds.

Key findings

  • Overall adherence to all three recommendations was 7.2%; the highest site prevalences were Australia (14.9%) and Canada (14.0%), and the lowest was China (1.5%).
  • Children meeting all three recommendations had lower odds of obesity than those meeting none: total sample OR 0.28 (95% CI 0.18–0.45); boys OR 0.38 (95% CI 0.22–0.64); girls OR 0.11 (95% CI 0.04–0.35). The paper states children meeting the three recommendations were 72% less likely to be obese than those who did not meet them.
  • Meeting any single recommendation was generally associated with lower obesity odds, especially MVPA: total sample OR 0.45 (95% CI 0.38–0.52) for MVPA, OR 0.67 (95% CI 0.58–0.77) for sleep, and OR 0.86 (95% CI 0.75–0.98) for screen time.
  • Meeting all three recommendations was associated with the lowest BMI z-score: total sample 0.01 vs 0.49 for not meeting; boys 0.07 vs 0.58; girls −0.05 vs 0.41.

Methods

  • Cross-sectional analysis of ISCOLE data collected September 2011–December 2013 from 6,128 children aged 9–11 years across 12 countries. From 7,372 ISCOLE participants, exclusions were invalid accelerometry (n = 1,214), missing screen time (n = 25), and missing BMI (n = 5).
  • MVPA and sleep duration were assessed with 24-hour waist-worn Actigraph GT3X+ accelerometry; screen time was self-reported; height and weight were measured, BMI was calculated, and BMI z-scores used WHO age- and sex-specific reference data. Obesity was BMI z-score > +2 SD. Meeting guidelines was defined as 9–11 h/night sleep, ≤2 h/day screen time, and ≥60 min/day MVPA.
  • Associations with obesity were assessed with odds ratios from generalized linear mixed models; differences in BMI z-scores were examined with linear mixed models. Models adjusted for age, sex, highest parental education, and unhealthy diet pattern score; study sites were fixed effects and schools nested within sites were random effects.

Limitations

  • Stated in the paper: the cross-sectional design precludes cause-and-effect associations; possible residual confounding by unmeasured variables; sleep duration was analyzed without a measure of sleep quality; screen time was self-reported; and findings have limited generalizability to the whole population.
  • Evident in the text: participants excluded for missing data had significantly higher BMI z-scores (0.61) than those included (0.46), suggesting possible selection bias; within-site samples were not intended to be nationally representative.
  • Evident in the text: analyses by study site were not possible due to lack of statistical power for certain combinations of movement behaviors.

    The Canadian 24-h movement guidelines thresholds (9–11 h/night sleep, ≤2 h/day screen time, ≥60 min/day MVPA) are appropriate for children in all 12 ISCOLE countries.

    “Meeting the overall 24-h movement guidelines was defined as: 9 to 11 h/night of sleep, ≤2 h/day of screen time, and at least 60 min/day of MVPA.”
    “The 24-h movement guidelines recently developed in Canada represent a paradigm shift in thinking about movement behaviors [4] from a focus on a single specific movement behavior type (e.g., MVPA) to an integrated movement behavior model.”
  • The paper relies on this without support.

    Exclusion of participants with missing data did not materially bias the associations between movement behaviors and adiposity.

    “Participants excluded due to missing data had significantly higher BMI z-scores (0.61) compared to those included in the present analytical sample (0.46).”
  • The paper relies on this without support.

    The main analyses had sufficient statistical power to detect the reported associations.

    “Models were presented for the total sample and by sex only; analyses by study site were not possible due to a lack of statistical power for certain combinations of movement behaviors.”
  • The paper relies on this without support.

    Self-reported screen time is a valid measure of screen time in all 12 participating countries.

    “Although not tested individually in every participating country, the TV viewing time question was shown to have adequate reliability with a one week test-retest interval (Spearman correlation = 0.55–0.68) and validity as compared to 7-day TV time use logs (Spearman correlation = 0.47) [28].”

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.

Claims read by deepseek-v4.1-flash under definition version 3 (extract-v3) on 2026-10-10.

Classified by jev-1.13-20260917 (gold-guideline-v0.2) on 2026-10-10.

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.
