STUDY OBJECTIVES
Although weekend catch-up sleep is common among children, the association between weekend catch-up sleep and executive functions remains unclear. We aimed to determine whether weekend catch-up sleep was related to executive functions in school-aged children.
METHODS
We analyzed data for 4,699 children (9.00 years ± 1.73 years old, 52.9% boys) from 5 primary schools in Guangzhou, China. Executive functions performance was examined by the Behavior Rating Inventory of Executive Function Parent Form. Validated self-report questionnaires were used to assess sleep status, socioeconomic status, and health behaviors. Multiple linear regression analyses were used to assess the association of weekend catch-up sleep duration with executive functions.
RESULTS
Weekday sleep was negatively associated with scores on three composite indices (Behavioral Regulation Index, Metacognition Index, Global Executive Composite), while weekend catch-up sleep was positively associated with them. Children with < 9 hours weekday sleep duration had higher scores in all indices, and there was no correlation between weekend catch-up sleep and scores of all indices (P > .05). For children who slept ≥ 9 hours on weekdays, weekend catch-up sleep of more than 1 hour was associated with increased scores of Behavioral Regulation Index, Metacognition Index, and Global Executive Composite (P < .05). There was no interaction between sex, age, and weekend catch-up sleep and executive functions (P > .05).
CONCLUSIONS
Weekend catch-up sleep could not restore the executive functions deficits related to short weekday sleep. Weekend catch-up sleep over 1 hour may have adverse effects on executive functions in school-aged children.

研究目的
尽管周末补觉在儿童中很常见，但周末补觉与执行功能之间的关联仍不明确。我们旨在确定周末补觉是否与学龄儿童的执行功能有关。
方法
我们分析了来自中国广州5所小学的4699名儿童（9.00岁±1.73岁，52.9%为男孩）的数据。执行功能表现通过执行功能家长版行为评定量表进行评估。使用经过验证的自我报告问卷来评估睡眠状况、社会经济地位和健康行为。采用多元线性回归分析来评估周末补觉时长与执行功能之间的关联。
结果
平日睡眠与三个综合指数（行为调节指数、元认知指数、整体执行综合指数）的得分呈负相关，而周末补觉与这些指数呈正相关。平日睡眠时间<9小时的儿童在所有指数上得分更高，且周末补觉与所有指数得分之间无相关性（P>.05）。对于平日睡眠≥9小时的儿童，周末补觉超过1小时与行为调节指数、元认知指数和整体执行综合指数得分增加相关（P<.05）。性别、年龄与周末补觉和执行功能之间不存在交互作用（P>.05）。
结论
周末补觉无法恢复与平日短睡眠相关的执行功能缺陷。周末补觉超过1小时可能对学龄儿童的执行功能产生不利影响。
