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. 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. 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. 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.

符合早期《澳大利亚24小时运动指南》的生理，心理和教育成果的预期联系。

几个国家/地区发布了5岁以下儿童运动指南，其中包括睡眠，体育锻炼和久坐行为的指南。这项研究检查了学龄前儿童遵守澳大利亚24小时运动指南（睡眠，体育锻炼，放映时间）以及小学期间生理，心理和教育成果的预期关联。数据来自健康活跃的学龄前和小学学习（澳大利亚墨尔本； n = 471； 3-5岁； 2008/9）。随访发生在基线后的第3年（2011/12； 6-8岁），第6年（2014/15； 9-11岁）和第7年（2016； 10-12岁）。多元回归模型评估了基线时对指南的依从性与以后结果之间的关联。儿童在基线时为4.6岁（男孩为53％；社会经济地位较高的家庭为62％）。大多数儿童符合体育锻炼（89％）和睡眠（93％）的指导原则；23％的人符合屏幕时间准则；有20％的人在基线时符合所有准则。满足所有这三个准则与9-11岁时较低的BMI z得分相关（b = − 0.26，95％CI -0.47，− 0.05）。达到体育锻炼准则与在10至12岁时更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。年龄。符合睡眠准则可以更好地阅读（b = 37.60，95％CI 6.74，68.46），拼写（b = 34.95，95％CI 6.65，63.25），算术（b = 39.09，95％CI 11.75，66.44），语言（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。没有证据表明符合筛选时间指南或社会心理结果。遵守不同的运动行为准则会导致不同的结果。必须采取支持儿童达到所有准则的策略，以最大程度地提高健康和教育成果。未来研究剂量反应关联性和潜在机制的研究是必要的。
