TL;DR: A large majority of children are insufficiently active, according to current recommended levels for health, after adjustment for age, sex, season, maternal age and social class.
Journal ArticleDOI

TL;DR: The prediction equation and the derived cut-points will help to better interpret the output of the Actigraph in children aged 12 years and the cut-point for moderate to vigorous physical activity is higher than that reported previously.
