The onset of monophasic sleep, in which napping ceases and sleep consolidates into a single night period, is a key developmental milestone of childhood. Yet to date, there is little consensus regarding the timing of cessation of napping in children. The aim of the current study is to examine global evidence regarding napping patterns in childhood, and, through meta-analysis, describe patterns of napping cessation and duration observed in children aged 0–12 y. A systematic search of all published, original research articles reporting children's napping patterns, by age, was conducted. The quality of studies was assessed, and meta-analysis of eligible studies undertaken. Risk of bias and heterogeneity of measurement was high. Current evidence indicates that less than 2.5% of children cease napping prior to age 2, while 94% cease napping by age 5. The preschool period (3–5 y; 36–60 mo) represents a particularly dynamic period in napping cessation, with large variation in rates of napping across studies evidencing potential ecological effects. Future studies should focus on understanding of the underlying mechanisms explaining individual variations in napping patterns and the extent to which patterns of napping may represent a marker of child development.

单相睡眠的开始，其中午睡停止，睡眠巩固在一个晚上，是儿童时期的一个重要发展里程碑。然而，迄今为止，关于停止儿童午睡的时间几乎没有达成共识。本研究的目的是检查有关儿童午睡模式的全球证据，并通过荟萃分析描述在 0-12 岁儿童中观察到的午睡停止模式和持续时间。对所有已发表的原创研究文章进行了系统搜索，这些文章报告了按年龄划分的儿童午睡模式。评估了研究的质量，并对符合条件的研究进行了荟萃分析。偏倚和测量异质性的风险很高。目前的证据表明，不到 2.5% 的儿童在 2 岁之前停止午睡，而 94% 的儿童在 5 岁之前停止午睡。学龄前时期（3-5 岁；36-60 个月）代表了停止午睡的一个特别活跃的时期，在证明潜在生态影响的研究中，午睡率有很大差异。未来的研究应侧重于了解解释午睡模式个体差异的潜在机制，以及午睡模式在多大程度上可能代表儿童发育的标志。
