: The impact of midday napping on neurocognitive function in adolescents has not been well established. This study aimed to investigate the relationship between self-reported midday-napping behaviors and neurocognitive function in early adolescents. : The sample was comprised of 363 early adolescents (12.00 ± 0.38 years old) from Jintan, China. : Midday napping, nighttime sleep duration, and sleep quality were measured by self-reported questionnaires. Neurocognitive function was measured by the Penn Computerized Neurocognitive Battery (accuracy and reaction times). Generalized linear regression was used to analyze the relationships. : Sixty-four percent of our sample took more than 3 naps per week, and 70.11% reported nap durations of over 30 min. Participants with higher frequencies or longer durations of midday napping reported significantly better nighttime sleep quality ( < 0.05). Adjusted models showed that frequent nappers (5-7d/week) were significantly associated with heightened accuracy on tasks that measured sustained attention and nonverbal reasoning and faster reaction times on spatial memory compared with other frequency groups (s < 0.05). For napping duration subgroups, early adolescents who took naps of any length were estimated to have faster reaction speeds on the sustained attention task compared with participants who never napped (s < 0.05). However, only nappers with a moderate duration (31-60 min) tended to achieve both faster speeds (β = -38.28, = 0.02) and better accuracy (β = 3.90, = 0.04) on the sustained attention task. : Our findings suggest that there is an association between habitual midday napping and neurocognitive function in early adolescents, especially in China, where midday napping is a cultural practice.
: 午睡对青少年神经认知功能的影响尚未得到充分证实。本研究旨在调查青少年早期自我报告的午睡行为与神经认知功能之间的关系。: 样本由来自中国金坛的 363 名青少年（12.00±0.38 岁）组成。: 午睡、夜间睡眠时间和睡眠质量通过自我报告的问卷进行测量。神经认知功能通过宾夕法尼亚计算机神经认知电池（准确性和反应时间）进行测量。使用广义线性回归分析关系。: 我们样本中有 64%的人每周午睡超过 3 次，70.11%的人报告午睡时间超过 30 分钟。午睡频率较高或时间较长的参与者报告夜间睡眠质量显著更好（<0.05）。调整后的模型显示，频繁午睡者（每周 5-7 天）在测量持续性注意力和非言语推理的任务上的准确性更高，在空间记忆任务上的反应时间更快，与其他频率组相比差异显著（s<0.05）。对于午睡时间亚组，与从不午睡的参与者相比，午睡任何时间的青少年在持续性注意力任务上的反应速度估计更快（s<0.05）。然而，只有午睡时间适中（31-60 分钟）的人在持续性注意力任务上的速度（β=-38.28，=0.02）和准确性（β=3.90，=0.04）都有所提高。: 我们的研究结果表明，习惯性午睡与青少年早期的神经认知功能之间存在关联，特别是在中国，午睡是一种文化习惯。
