Although many studies have reported on physical activity (PA) levels using accelerometers, a thorough description of the PA pattern in preschool children during their stay in the preschool, is lacking in the current literature. Furthermore, there remains a lack of understanding of the PA level and pattern in children in the lower end of the PA continuum.The first aim of this study was therefore to describe the PA pattern during a week-long stay in a preschool in all children born in 2011 (either three or four-year-olds) attending public preschools in a municipality in Norway. The second aim was to describe the PA level and pattern of the children who are the least physically active.This cross-sectional study included baseline data from 95% of children (N = 111) participating in a randomized controlled physical activity intervention (Active Kindergarten – Active Children study). The participants wore an Actigraph accelerometer, in week 39 in 2015, from when they arrived at the preschool on Monday morning and throughout their stay of five consecutive days.The amount of moderate- to vigorous-intensity PA (MVPA) per day ranged from 16 min to 116 min, and sedentary time ranged from 2.7 h to 6.5 h per day in the least and most sedentary child, respectively. The least physically active 25% of children were less active throughout the entire day, and only a few of them managed to achieve the recommended level of MVPA on any weekday.The physical activity levels and patterns among the least active children described in this study may help to inform interventions targeting this group.

Background 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. Methods 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. Results 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 < 0.01) and reduced sedentary time with 14 min/day (95% CI = − 27, − 1; P = 0.04) compared to the control group. The intervention group had a 2.4 higher odds (95% CI = 1.05, 5.7; P = 0.04) of meeting the PA recommendations compared to the control group at follow-up. Conclusions Our results show that a flexible staff-led and expert-supported multicomponent PA intervention can increase total PA level, moderate- and vigorous intensity PA and reduce time spent sedentary in three to four-year old children during their stay in ECEC settings. Trial registration The trial was retrospectively registered on September 19, 2020 and available online at ClinicalTrials.gov: No. NCT04555746.

I denne artikkelen presenteres en studie som undersøker hvordan et kollegialt samarbeidsprosjekt formes og påvirkes av digital teknologi. Studien er et selvstudium gjort av fire laererutdannere i barnehagelaererutdanningen fra tre forskjellige campuser, som samarbeidet digitalt om å utvikle egen undervisningspraksis. I studien ble erfaringene våre fra det digitale samarbeidet samlet i individuelle refleksjonslogger. Loggene ble analysert med tematisk analyse. Resultatene viser at de digitale plattformene ga en annen og en tettere tilgang til felles tekst som medførte at samskriving i sanntid fordret til refleksjoner, erfaringsdeling og faglige diskusjoner. Gjennom det digitale samarbeidet opplevde deltakerne at den digitale kompetansen deres ble utviklet, selv om digital kompetanse ikke var fokuset for utviklingsprosjektet. Arbeidsformen opplevdes fleksibel, men det var behov for jevnlige nettmøter for å opprettholde motivasjon og fremdrift. Konklusjonen er at kollegialt digitalt samarbeid kan bidra til utvikling av egen undervisnings-og forskningskompetanse og digital kompetanse samt styrke samarbeid uavhengig av geografi. For å stimulere til slikt samarbeid må utdanningsinstitusjoner prioritere og legge til rette for kollegialt utviklingsarbeid gjennom ressurstildeling og gode støttefunksjoner.

Background: A growing body of evidence suggests that children’s physical activity (PA) level in early childhood education and care (ECEC) settings is 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, ECEC settings may serve as an ideal avenue for increasing PA level, reducing sedentary time and enhancing the overall health of young children. This paper investigates the effectiveness of the “Active Kindergarten – Active Children” study in increasing children’s PA level and reducing sedentary time within the ECEC setting. Methods: Accelerometers were used to assess PA and sedentary time. A total of 116 three- to four-year-olds took part in a randomized controlled trial in 11 ECEC settings. The participants were cluster-randomized, by ECEC setting, to either a 12-week staff-led and expert-supported intervention or a waiting-list control group. Results: 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˂0.01) and reduced sedentary time by 14 min/day (95% CI = -27, -1; P=0.04) compared to the control group. The intervention group was 2.4 times more likely (95% CI = 1.05, 5.7; P = 0.04) to meet the PA recommendations than the control group at follow-up. Conclusions: Our results show that a flexible staff-led and expert-supported multi-component PA intervention can increase the total PA level and moderate- and vigorous-intensity PA and reduce sedentary time in three- to four-year-old children during their stay in ECEC settings.
