The aim of this systematic review was to examine the associations between physical activity and sleep in children aged less than 6 years. Articles were included if participants were primarily aged less than 6 years and study designs were observational or experimental. Study characteristics were extracted, and the Grading Recommendations Assessment, Development and Evaluation framework was used to assess study quality. Thirty-six studies (16 sleep, 16 physical activity, and three fitness outcomes) from 18 countries reported in 29 articles were included. The majority of sleep and physical activity outcome studies reported mixed effects with very low to low quality of evidence. Fitness outcome studies were limited, and therefore, evidence was insufficient. The high prevalence of mixed and null results could be related to study limitations. Importantly, this review points to the critical need for higher quality studies of sleep and physical activity in young children, which would support health recommendations and intervention strategies for healthier child development.
本系统评价的目的是研究6岁以下儿童的身体活动与睡眠之间的关联。如果研究参与者主要为6岁以下儿童，且研究设计为观察性或实验性，则纳入相关文章。提取研究特征，并使用推荐分级评估、发展和评价框架来评估研究质量。纳入了29篇文章中报道的来自18个国家的36项研究（16项睡眠研究、16项身体活动研究和3项健康状况研究）。大多数睡眠和身体活动结果研究报告的是混合效应，证据质量极低至低。健康状况研究有限，因此证据不足。混合结果和无结果的高发生率可能与研究局限性有关。重要的是，本综述指出迫切需要对幼儿的睡眠和身体活动进行更高质量的研究，这将为更健康的儿童发育的健康建议和干预策略提供支持。
