N1 - Funding Information:
We would like to thank all participants and funders of the original studies that contributed data to ICAD. The pooling of the data was funded through a grant from the National Prevention Research Initiative (Grant number: G0701877) ( http://www.mrc.ac.uk/research/initiatives/national-prevention-research-initiative-npri/ ). The funding partners relevant to this award are: British Heart Foundation; Cancer Research UK; Department of Health; Diabetes UK; Economic and Social Research Council; Medical Research Council; Research and Development Office for the Northern Ireland Health and Social Services; Chief Scientist Office; Scottish Executive Health Department; The Stroke Association; Welsh Assembly Government and World Cancer Research Fund. This work was additionally supported by the Medical Research Council [ MC_UU_12015/3 ; MC_UU_12015/7 ], Bristol University , Loughborough University and Norwegian School of Sport Sciences . We acknowledge the Centre for Diet and Activity Research (CEDAR), a UKCRC Public Health Research Centre of Excellence. Funding from the British Heart Foundation , Cancer Research UK , Economic and Social Research Council , Medical Research Council , the National Institute for Health Research , and the Wellcome Trust , under the auspices of the UK Clinical Research Collaboration, is gratefully acknowledged. We also gratefully acknowledge the contribution of Professor Chris Riddoch, Professor Ken Judge and Dr. Pippa Griew to the development of ICAD.

N2 - Physical activity declines during youth but most evidence reports on combined moderate and vigorous-intensity physical activity. We investigated how vigorous-intensity activity varies with age.Cross-sectional data from 24,025 participants (5.0-18.0 y; from 20 studies in 10 countries obtained 2008-2010) providing =. 1 day accelerometer data (International Children's Accelerometry Database (ICAD)). Linear regression was used to investigate age-related patterns in vigorous-intensity activity; models included age (exposure), adjustments for monitor wear-time and study. Moderate-intensity activity was examined for comparison. Interactions were used to investigate whether the age/vigorous-activity association differed by sex, weight status, ethnicity, maternal education and region.A 6.9% (95% CI 6.2, 7.5) relative reduction in mean vigorous-intensity activity with every year of age was observed; for moderate activity the relative reduction was 6.0% (5.6%, 6.4%). The age-related decrease in vigorous-intensity activity remained after adjustment for moderate activity. A larger age-related decrease in vigorous activity was observed for girls (-. 10.7%) versus boys (-. 2.9%), non-white (-. 12.9% to -. 9.4%) versus white individuals (-. 6.1%), lowest maternal education (high school (-. 2.0%)) versus college/university (ns) and for overweight/obese (-. 6.1%) versus healthy-weight participants (-. 8.1%). In addition to larger annual decreases in vigorous-intensity activity, overweight/obese individuals, girls and North Americans had comparatively lower average vigorous-intensity activity at 5.0-5.9 y.Age-related declines in vigorous-intensity activity during youth appear relatively greater than those of moderate activity. However, due to a higher baseline, absolute moderate-intensity activity decreases more than vigorous. Overweight/obese individuals, girls, and North Americans appear especially in need of vigorous-intensity activity promotion due to low levels at 5.0-5.9 y and larger negative annual differences
