title = "Development of evening sleep homeostatic pressure in early adolescent boys",
abstract = "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{\textquoteright} (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.",

Funding Information: This study was granted ethics approval from the Flinders University Social and Behavioural Research Ethics Committee. Parents of potential child participants underwent an initial phone screening interview using items from the Sleep, Medical, Educational, and Family History Form [16]. If they passed screening, a brief face-to-face interview was arranged with the child and parent at the sleep laboratory, so as to fully explain the procedures of the study, familiarize the child with the sleep lab environment and equipment (i.e., polysomnography), and obtain written informed consent. The child and parent were then provided with two 7-day sleep diaries to complete in conjunction with wearing wrist actigraphy (i.e., Minimitter; AMI Inc., Ardsley, NY, USA).This project received partial funding from an Australian Research Council Discovery Project (DP150100215), and additional funding from Flinders University.
