School recess provides a daily opportunity for children to engage in physically active behaviours. However, few studies have investigated what factors may influence children's physical activity levels in this context. Such information may be important in the development and implementation of recess interventions. The aim of this study was to investigate the association between a range of recess variables and children's sedentary, moderate and vigorous physical activity in this context.
One hundred and twenty-eight children (39% boys) aged 9-10 years old from 8 elementary schools had their physical activity levels observed during school recess using the System for Observing Children's Activity and Relationships during Play (SOCARP). Playground variables data were also collected at this time. Multilevel prediction models identified variables that were significantly associated with children's sedentary, moderate and vigorous physical activity during recess.
Girls engaged in 13.8% more sedentary activity and 8.2% less vigorous activity than boys during recess. Children with no equipment provision during recess engaged in more sedentary activity and less moderate activity than children provided with equipment. In addition, as play space per child increased, sedentary activity decreased and vigorous activity increased. Temperature was a significant negatively associated with vigorous activity.
Modifiable and unmodifiable factors were associated with children's sedentary, moderate and vigorous physical activity during recess. Providing portable equipment and specifying areas for activities that dominate the elementary school playground during recess may be two approaches to increase recess physical activity levels, though further research is needed to evaluate the short and long-term impact of such strategies.
课间休息为孩子们提供了每天参与身体活动的机会。然而，很少有研究调查在这种情况下哪些因素可能影响儿童的身体活动水平。这些信息对于制定和实施课间休息干预措施可能很重要。本研究的目的是调查一系列课间休息变量与儿童在这种情况下的久坐、中等和剧烈身体活动之间的关系。
从 8 所小学的 128 名 9-10 岁的儿童（39%为男孩）在课间休息期间使用观察儿童在游戏中的活动和关系系统（SOCARP）观察他们的身体活动水平。同时还收集了操场变量数据。多水平预测模型确定了与儿童课间休息期间久坐、中等和剧烈身体活动显著相关的变量。
女孩在课间休息时比男孩多进行 13.8%的久坐活动，少进行 8.2%的剧烈活动。课间休息时没有设备供应的儿童比有设备供应的儿童进行更多的久坐活动和较少的中等活动。此外，随着每个孩子的游戏空间增加，久坐活动减少，剧烈活动增加。温度与剧烈活动呈显著负相关。
可改变和不可改变的因素与儿童在课间休息时的久坐、中等和剧烈身体活动有关。在课间休息时提供便携式设备并指定活动区域，以主导小学操场，可能是增加课间休息身体活动水平的两种方法，但需要进一步研究来评估这些策略的短期和长期影响。
