Despite recent research showing that early childhood education and daycare settings (ECEC) have an important role in promoting toddlers' physical activity (PA), crucial information gaps remain regarding toddlers' PA and sedentary behavior (SB) in these outdoor settings. We aimed in this study to: (a) analyze PA patterns and SB during unstructured outdoor play time in preschool and daycare environments using accelerometry and systematic observation; (b) provide concurrent accelerometry and observational data to help validate the Observational System for Recording Physical Activity in Children-Preschool Version (OSRAC-P); and (c) examine individual, social and environmental correlates of PA and SB during toddlers' unstructured outdoor play time. We found that: (a) toddlers displayed high amounts of PA with no sex, BMI, and/or age differences in PA and SB levels,; (b) environmental variables (e.g., fixed equipment and playground density) were not associated with PA levels or SB intensity; (c) the OSRAC-P was a reliable and valid means of observing and analyzing toddlers' PA patterns during unstructured outdoor play time; and (e) different social patterns between boys and girls did not impact PA levels or patterns. Combining different measurement methods permitted an improved understanding of unstructured outdoor play in preschool and daycare settings.
尽管最近的研究表明，幼儿教育和日托环境在促进幼儿身体活动（PA）方面发挥着重要作用，但在这些户外环境中，关于幼儿的身体活动和久坐行为（SB）仍存在关键的信息空白。本研究的目的是：（a）使用加速度计和系统观察法分析学龄前和日托环境中无组织户外玩耍时间的身体活动模式和久坐行为；（b）提供同步的加速度计和观察数据，以帮助验证《儿童身体活动记录观察系统-学龄前版》（OSRAC-P）；（c）研究幼儿无组织户外玩耍时间内身体活动和久坐行为的个体、社会和环境相关因素。我们发现：（a）幼儿表现出大量的身体活动，在身体活动和久坐行为水平上不存在性别、BMI和/或年龄差异；（b）环境变量（如固定设备和操场密度）与身体活动水平或久坐行为强度无关；（c）OSRAC-P是观察和分析幼儿无组织户外玩耍时间身体活动模式的可靠且有效的方法；（e）男孩和女孩之间不同的社交模式不会影响身体活动水平或模式。结合不同的测量方法有助于更好地理解学龄前和日托环境中的无组织户外玩耍情况。
