Associations between educators' and children's physical activity and sedentary time in Norwegian preschools: A cross-sectional study.

Preschool educators may be important role models influencing children's physical activity (PA) behaviours. The main aim of this paper was to examine the relationship between educators' and children's PA and sedentary time (SED) by including 1230 children (mean age 4.8 yrs, 48% girls) and 422 educators (mean age 42.4 yrs, 90% women) from 68 preschools in Western Norway. PA and SED were measured over 10 preschool days using hip worn ActiGraph GT3×+ accelerometers. Associations between child and educator PA and SED during preschool hours, determined by multivariate pattern analyses, provided explained variances (R) = 2.8-5.2%. Levels of educator moderate PA were positively related to child PA (all intensities) and educator vigorous PA were positively related to child vigorous PA, while educator light PA was negatively associated with PA and positively associated with child SED. Educator SED were positively associated with child vigorous PA and negatively associated to child SED. Association patterns were similar for boys and girls, while educator moderate and vigorous PA were more strongly related to the younger vs. the older children's PA. The positive relationships between educators' moderate and vigorous PA and children's PA found herein suggest educators' PA behaviours should be addressed in future interventions.
