背景 一些国家已经发布了针对 5 岁以下儿童的运动指南，其中包括睡眠、体力活动和久坐行为指南。本研究探讨了学龄前儿童遵守澳大利亚 24 小时运动指南（睡眠、体力活动、屏幕时间）与小学期间生理、心理和教育成果之间的前瞻性关联。方法 数据来自健康活跃学前班和小学研究（澳大利亚墨尔本；n = 471；3-5 岁；2008/9）。随访发生在基线后第 3 年（2011/12 年；6-8 年）、6 年（2014/15 年；9-11 年）和 7 年（2016 年；10-12 年）。多元回归模型评估了基线时遵循指南与后期结果之间的关联。结果 儿童基线年龄为 4.6 岁（53% 为男孩；62% 为高社会经济家庭）。大多数儿童符合体力活动（89%）和睡眠（93%）准则； 23% 的人符合屏幕时间准则； 20% 的人在基线时符合所有准则。满足所有三个指南与 9-11 岁时较低的 BMI z 分数相关 (b = - 0.26, 95%CI -0.47, - 0.05)。满足体力活动指南与 10-12 岁时较高的全身骨矿物质密度 (b = 0.64, 95%CI 0.15, 1.13) 和全身骨矿物质含量 (b = 183.19, 95%CI 69.92, 296.46) 相关。符合睡眠指南与更好的阅读能力 (b = 37.60, 95%CI 6.74, 68.46)、拼写能力 (b = 34.95, 95%CI 6.65, 63.25)、算术能力 (b = 39.09, 95%CI 11.75, 66.44) 和语言能力 (b = 44.31, 95%CI 11.77, 76.85) 和写作 (b = 25.93, 95%CI 0.30, 51.57) 在 8-9 岁时。对于遵守屏幕时间指南或心理社会结果没有明显的关联。结论 遵守不同的运动行为指南与不同的结果相关。支持儿童满足所有指导方针的策略是必要的，以最大限度地提高健康和教育成果。未来研究剂量反应关联和潜在机制是必要的。
Background Several countries have released movement guidelines for children under 5 that incorporate guidelines for sleep, physical activity and sedentary behavior. This study examines prospective associations of preschool children's compliance with the 24-Hour Australian movement guidelines (sleep, physical activity, screen time) and physiological, psychosocial and educational outcomes during primary school. Methods Data were from the Healthy Active Preschool and Primary Years Study (Melbourne, Australia; n = 471; 3-5 years; 2008/9). Follow-ups occurred at 3 (2011/12; 6-8 years), 6 (2014/15; 9-11 years) and 7 (2016; 10-12 years) years post baseline. Multiple regression models assessed associations between compliance with guidelines at baseline and later outcomes. Results Children were 4.6 years at baseline (53% boys; 62% high socio-economic families). Most children met physical activity (89%) and sleep (93%) guidelines; 23% met screen-time guidelines; and 20% met all guidelines at baseline. Meeting all of the three guidelines was associated with lower BMI z-scores at 9-11 years of age (b = - 0.26, 95%CI -0.47, - 0.05). Meeting physical activity guidelines was associated with higher total body bone mineral density (b = 0.64, 95%CI 0.15, 1.13), and total body bone mineral content (b = 183.19, 95%CI 69.92, 296.46) at 10-12 years of age. Meeting sleep guidelines was associated with better reading (b = 37.60, 95%CI 6.74, 68.46), spelling (b = 34.95, 95%CI 6.65, 63.25), numeracy (b = 39.09, 95%CI 11.75, 66.44), language (b = 44.31, 95%CI 11.77, 76.85) and writing (b = 25.93, 95%CI 0.30, 51.57) at 8-9 years of age. No associations were evident for compliance with screen-time guidelines or for psychosocial outcomes. Conclusions Compliance with different movement behavior guidelines was associated with different outcomes. Strategies to support children in meeting all of the guidelines are warranted to maximize health and educational outcomes. Future research investigating dose-response associations, and potential mechanisms, is necessary.
