Objectively measured physical activity and sedentary time in youth: the International Children's Accelerometry Database (ICAD)
Open accessAbstract
BACKGROUND: Physical activity and sedentary behaviour in youth have been reported to vary by sex, age, weight status and country. However, supporting data are often self-reported and/or do not encompass a wide range of ages or geographical locations. This study aimed to describe objectively-measured physical activity and sedentary time patterns in youth. METHODS: The International Children's Accelerometry Database (ICAD) consists of ActiGraph accelerometer data from 20 studies in ten countries, processed using common data reduction procedures. Analyses were conducted on 27,637 participants (2.8-18.4 years) who provided at least three days of valid accelerometer data. Linear regression was used to examine associations between age, sex, weight status, country and physical activity outcomes. RESULTS: Boys were less sedentary and more active than girls at all ages. After 5 years of age there was an average cross-sectional decrease of 4.2% in total physical activity with each additional year of age, due mainly to lower levels of light-intensity physical activity and greater time spent sedentary. Physical activity did not differ by weight status in the youngest children, but from age seven onwards, overweight/obese participants were less active than their normal weight counterparts. Physical activity varied between samples from different countries, with a 15-20% difference between the highest and lowest countries at age 9-10 and a 26-28% difference at age 12-13. CONCLUSIONS: Physical activity differed between samples from different countries, but the associations between demographic characteristics and physical activity were consistently observed. Further research is needed to explore environmental and sociocultural explanations for these differences.

TL;DR
This pooled analysis of ActiGraph accelerometer data from 20 studies in ten countries described physical activity and sedentary time in 27,637 youth aged 2.8–18.4 years. It found consistent sex, age, and weight-status differences, plus substantial between-country variation, despite use of common data-reduction procedures.
Key findings
- Boys were less sedentary and more active than girls at all ages. After age 5, total physical activity decreased cross-sectionally by an average of 4.2% per additional year (3.7% in boys, 4.6% in girls), mainly through lower light-intensity activity and greater sedentary time.
- Physical activity did not differ by weight status in the youngest children, but from age seven onwards overweight/obese participants were less active than normal-weight peers; this showed a dose–response relationship in both sexes and was particularly large in boys.
- Between-country differences were substantial: at age 9–10 the difference between the least active population (Madeira) and most active (Oslo, Norway) was 15–20% (156 cpm in boys, 613 vs. 769; 99 cpm in girls, 561 vs. 660), and at age 12–13 it was 26–28%.
- Among 5–17 year olds in ICAD, only 9.0% of boys and 1.9% of girls achieved ≥60 min MVPA every valid day; ≥60 min MVPA was accumulated on 46% of valid days for boys and 22% for girls, with Norwegian boys aged 9–10 recording the highest values (60.5% of measured days).
Methods
- ICAD pooled ActiGraph accelerometer data from 20 studies in ten countries using a standard data-reduction procedure. Analyses included 27,637 participants (92% of 29,967 potential participants) aged 2.8–18.4 years with at least 3 valid days (mean 5.3, range 3–7), providing 188,416 valid days across 35,360 time points.
- Linear regression examined cross-sectional associations between age, sex, weight status, and physical activity outcomes, adjusted for study and season; robust standard errors accounted for repeated measures within participants. Country comparisons were restricted to ages 9–15 and ten studies from eight countries, using standardized within-country outcomes and random-effects meta-analysis.
- Physical activity outcomes included average accelerometer counts per minute (cpm) and percentage time sedentary (≤100 cpm), light (101–2295 cpm), and moderate-to-vigorous (≥2296 cpm). Guideline achievement was presented as ≥60 min MVPA on every valid day and as the percentage of valid days with ≥60 min MVPA.
Limitations
- The paper states that the sample was skewed toward ages 9–15 (82% of measurement time points) and the UK and USA (73% of measurement time points); some countries had too few participants for country-level analysis, countries were not globally representative, and low- and middle-income countries were underrepresented. Most samples were not nationally representative, though generally at least regionally representative.
- The paper states accelerometer limitations: waist-worn accelerometers poorly record upper-body activity and cycling, potentially underestimating activity in high-cycling countries such as Denmark; they misclassify motionless-standing as sedentary, potentially overestimating sedentary time; and the MVPA thresholds perform poorly for ages 4–6 and are not validated under age 4.
- The paper notes that direction of causation between weight status and physical activity was not investigated and may be bidirectional, and that individual, social, and environmental explanations for between-country differences were not explored. Evident from the text: girls were over-represented (59%, falling to 52% after excluding one large study of adolescent girls), which may affect descriptive proportions.

“In addition, waist-worn accelerometers mis-classify time spent in motionless-standing as sedentary, which is not considered to be a sedentary behaviour (defined as “any waking behaviour characterised by an energy expenditure ≤1.5 metabolic equivalents (METs) while in a sitting or reclining posture” [35]), potentially leading to over estimates of the true volume of sedentary time.”

In the paper
“When worn on the waist, as in the studies comprising the ICAD, they poorly record upper body physical activity and physical activity when cycling [34]. Thus, in countries with a high prevalence of cycling for transportation (e.g. Denmark), physical activity may be under-estimated.”

“Whilst the thresholds used have been shown to provide valid estimates of physical activity intensity for youth aged 5 years and above [36], more recently they have been shown to perform poorly for MVPA in children aged 4–6 years [37] and have not been validated in children under 4 years.”

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 2026-10-08, under version 3 of the claim definition (model deepseek-v4.1-flash, prompt extract-v3).
A second model labelled each claim on 2026-10-08 (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.
