The physiological processes governing sleep regulation show maturational changes during adolescent development. To date, data are available to specify when delays in circadian timing occur; however, no longitudinal data exist to characterize the maturation of the accumulation of sleep pressure across the evening. The aim of this longitudinal study was to test whether this change in evening sleep propensity can be identified during early adolescence. Twenty pre-pubescent boys' (Mage = 10.3, SD = 0.4 years) evening sleep homeostats were assessed using a series of sleep latency tests every hour (7:30 p.m. to 3:30 a.m.) at 6-month intervals across four waves. While results revealed shorter sleep onset latencies with increasing wakefulness (p < .001), this effect was not moderated by study wave (p = .79). Evening sleep propensity thus appears to remain stable in boys during early adolescence. Future studies should expand upon these findings by using larger samples of girls as well as boys across an extended age range during the teenage years.
睡眠调节的生理过程在青少年发育期间表现出成熟变化。迄今为止，已有数据可确定昼夜节律时间延迟发生的时间；但是，尚无纵向数据来描述睡眠压力在晚上的积累的成熟过程。本纵向研究的目的是测试在青春期早期是否可以识别这种夜间睡眠倾向的变化。使用一系列睡眠潜伏期测试，每隔 6 个月在四个波次中（晚上 7:30 到凌晨 3:30），对 20 名青春期前男孩（Mage = 10.3，SD = 0.4 岁）的夜间睡眠内稳态进行评估。虽然结果显示随着清醒时间的增加，睡眠潜伏期缩短（p <.001），但该效应不受研究波次的调节（p =.79）。因此，在青春期早期，男孩的夜间睡眠倾向似乎保持稳定。未来的研究应该通过使用更大的女孩样本以及男孩在青少年时期的更大年龄范围内来扩展这些发现。
