The objectives were to systematically investigate the multiple dimensions of sleep and their association with overweight or obesity among primary school‐aged children. CINHAL, PsycINFO, SPORTDiscus, Medline, Cochrane, Embase, and PubMed databases were searched for papers reporting on an association between children's sleep and weight status. Studies on clinical populations, published in languages other than English, without objectively measured weight status, or where weight status was reported outside the outlined age bracket (5‐13 years) were excluded. A total of 34 248 citations were extracted from our systematic search protocol, of which 112 were included for detailed review. Compared with sleep duration, of which 86/103 articles found a significant inverse association between sleep duration and measured weight status, few studies examined other dimensions of sleep, such as quality, efficiency and bed/wake times, and relationship with weight status. Where studies existed, variation in defining and measurement of these dimensions restricted comparison and potentially influenced discrepancies across results. Overall, the findings of this review warrant the need for further research of the outlined dimensions of sleep. Future research would benefit from clarity on definitions across the different dimensions, along with the use of valid and reliable tools.

儿童的睡眠和肥胖：对多个睡眠维度的系统评价。

目的是系统地研究睡眠的多个方面及其与小学学龄儿童超重或肥胖的关系。在CINHAL，PsycINFO，SPORTDiscus，Medline，Cochrane，Embase和PubMed数据库中进行搜索，以寻找报告儿童睡眠与体重状况之间相关性的论文。排除了以英语以外的其他语言发布，未客观测量体重状况或报告的体重状况不在概述的年龄段（5-13岁）内的临床人群研究。从我们的系统搜索协议中总共提取了34248条引用文献，其中112条被详细审核。与睡眠时间相比，其中有86/103篇文章发现睡眠时间与体重测量值之间存在显着的负相关关系，很少有研究检查睡眠的其他方面，例如质量，效率和上床/醒来时间，以及与体重状况的关系。在已有研究的地方，这些尺寸的定义和度量上的差异限制了比较，并可能影响结果之间的差异。总体而言，本次审查的结果证明有必要对概述的睡眠维度进行进一步研究。未来研究将受益于不同维度定义的清晰性以及有效和可靠工具的使用。这项审查的结果表明，有必要对概述的睡眠维度进行进一步研究。未来研究将受益于不同维度定义的清晰性以及有效和可靠工具的使用。这项审查的结果表明，有必要对概述的睡眠维度进行进一步研究。未来研究将受益于不同维度定义的清晰性以及有效和可靠工具的使用。
