调查的双重目的是（1）用直接观察数据描述学龄前儿童的身体活动行为以及伴随这些行为的社会和环境事件;（2）确定哪些环境条件是中度至剧烈身体活动（MVPA）和非久坐身体活动（即，轻度活动+ MVPA），适用于3、4和5岁的儿童在户外玩耍时。结果表明，学龄前儿童的身体活动的特点是在整个学龄前一天久坐不动（即，89%久坐，8%轻度活动，3% MVPA）。在户外玩耍期间，当孩子们最有可能进行身体活动时，一些背景和社会环境可以更好地预测他们的身体活动。政策制定者，从业人员和研究人员的影响进行了讨论。
The two-fold purpose of the investigation was (1) to describe with direct observation data the physical activity behaviors and the accompanying social and environmental events of those behaviors for children in preschools; and (2) to determine which contextual conditions were predictors of moderate-to-vigorous physical activity (MVPA) and non-sedentary physical activity (i.e., light activity + MVPA) for 3-, 4-, and 5-year-old children during their outdoor play. The results indicate that preschoolers’ physical activity is characterized as sedentary in nature throughout their preschool day (i.e., 89% sedentary, 8% light activity, 3% MVPA). During outdoor play periods, when children are most likely to be physically active, some contextual and social circumstances better predict their physical activity. Implications for policymakers, practitioners, and researchers are discussed.
