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.
学前教育工作者可能是影响儿童身体活动 (PA) 行为的重要榜样。本文的主要目的是通过纳入来自挪威西部 68 所幼儿园的 1230 名儿童（平均年龄 4.8 岁，48%为女孩）和 422 名教育工作者（平均年龄 42.4 岁，90%为女性），来检验教育工作者和儿童 PA 和久坐时间 (SED) 之间的关系。使用 Hip 佩戴的 ActiGraph GT3×+ 加速度计在 10 个学前日期间测量 PA 和 SED。通过多元模式分析确定学前时间内儿童和教育工作者 PA 和 SED 之间的关联，提供了解释方差 (R) = 2.8-5.2%。教育工作者适度 PA 水平与儿童 PA（所有强度）呈正相关，教育工作者剧烈 PA 与儿童剧烈 PA 呈正相关，而教育工作者轻度 PA 与 PA 呈负相关，与儿童 SED 呈正相关。教育工作者的 SED 与儿童剧烈 PA 呈正相关，与儿童 SED 呈负相关。男孩和女孩的关联模式相似，而教育工作者适度和剧烈 PA 与较年轻的儿童的 PA 比年长的儿童更密切相关。本研究中发现的教育工作者适度和剧烈 PA 与儿童 PA 之间的积极关系表明，未来的干预措施应关注教育工作者的 PA 行为。
