A growing body of evidence suggest that the children's physical activity (PA) level in early childhood education and care (ECEC) settings are insufficient. Since most children attend ECEC settings for many hours on most days of the week, and these institutions reach children across the socioeconomic spectrum, the ECEC settings may serve as an ideal avenue for increasing physical activity level, reduce sedentary time and enhance the overall health of young children. This paper investigates the effectiveness of the "Active Kindergarten - Active Children" study to increase children's PA level and reduce sedentary time within the ECEC setting.
Accelerometers were used to asses PA and sedentary time. A total of 116 three to four-year olds took part in a randomised controlled trial in 11 ECEC settings. Participants were cluster-randomised, by ECEC setting, to either a 12?week staff-led and expert-supported intervention or a waiting list control group.
The intervention group increased time spent in moderate- and vigorous intensity PA by 10?min/day (95% CI?=?3, 18; P?=?0.01), took 1909 more steps per day (95% CI?=?1130, 2688; P
