*Accumulating ≥60 min/day MVPA. The exact measure used to define adherence to this guideline varies across the studies tabulated: in MCS, Gateshead, SPEEDY and ALSPAC studies a mean of 60 min or more was used; in the CHASE study only the first day of measurement, and in the Health Survey only a subsample with 7 days of observation each with at least 60 min of MVPA/day.
ALSPAC, Avon Longitudinal Study of Parents and Children; CHAMPS, Children's Health and Activity Monitoring Programme in Schools; CHASE, Child Heart and Health Study; cpm, counts per minute; MCS, Millennium Cohort Study; MPVA, moderate-to-vigorous intensity physical activity; SPEEDY, Sport, Physical Activity and Eating Behaviour, Environmental Determinants in Young People.
