School recess provides a valuable opportunity for children's daily moderate- to vigorous-intensity physical activity (MVPA). This study aimed to quantify MVPA during school recess in a representative sample of Scottish children and examine whether recess MVPA varied by gender, socioeconomic status, season, urban/rural residency, and recess length.
Five-day accelerometry MVPA data were analyzed from 773 children (53.9% girls, 46.1% boys, 10- to 11-y-olds) from 471 schools. Binary logistic regression explored associations between meeting/not meeting the recommendation to spend 40% of recess time in MVPA and the aforementioned risk factors. Descriptive recess data were also analyzed.
Participants spent an average of 3.2 minutes (SD 2.1) in MVPA during recess. Girls engaged in 2.5 minutes (SD 1.7) of MVPA compared with 4.0 minutes (SD 2.2) for boys. Only 6% of children met the recess MVPA recommendation. The odds of girls (odds ratio 0.09; 95% confidence interval, 0.04-0.25) meeting the recommendation was lower (P < .001) compared with boys. No statistically significant differences were observed in meeting the recommendation for the other risk factors.
Levels of MVPA during school recess are very low in Scottish children, and interventions aimed at increasing MVPA during recess are needed.
课间休息为儿童日常中到高强度身体活动(MVPA)提供了宝贵的机会。本研究旨在量化苏格兰儿童代表性样本在课间休息时的 MVPA,并检验课间休息时的 MVPA 是否因性别、社会经济地位、季节、城乡居住和课间休息时间长短而有所不同。
从 471 所学校的 773 名儿童(53.9%女孩,46.1%男孩,10-11 岁)中分析了 5 天的加速计 MVPA 数据。使用二元逻辑回归探讨了达到/未达到建议的在 40%课间休息时间内进行 MVPA 的建议与上述风险因素之间的关联。还分析了描述性课间休息数据。
参与者在课间休息时平均进行 3.2 分钟(SD 2.1)的 MVPA。女孩进行了 2.5 分钟(SD 1.7)的 MVPA,而男孩进行了 4.0 分钟(SD 2.2)。只有 6%的儿童达到了课间 MVPA 的建议。与男孩相比(比值比 0.09;95%置信区间,0.04-0.25),女孩达到建议的可能性较低(P<0.001)。对于其他风险因素,未观察到达到建议的差异具有统计学意义。
苏格兰儿童在课间休息时的 MVPA 水平非常低,需要干预措施来增加课间休息时的 MVPA。
