“…It is worth noting that, similar to the current study, Okano et al [43] and Sridhar et al [44] also used wearable activity trackers to monitor sleep activity. Previous studies have demonstrated that electronic devices can accurately track sleep activity in students [50,[70][71][72][73].…”

“…In the past two decades, much research has been conducted to examine the associations between sleep and GPA [ 33 , 36 , 37 ]. There is increasing evidence that GPA can, to some degree, be predicted by certain sleep measures, including sleep duration [ 38 , 39 , 40 , 41 , 42 , 43 , 44 , 45 ] and sleep quality [ 42 , 43 , 46 , 47 , 48 , 49 , 50 , 51 ].…”

Although the relationship between sleep and academic performance has been extensively examined, how sleep predicts future academic performance (e.g., 2–3 years) remains to be further investigated. Using wearable smartwatches and a self-report questionnaire, we tracked sleep activities of 45 college students over a period of approximately half a month to see whether their sleep activities predicted their academic performance, which was estimated by grade point average (GPA). Results showed that both nighttime sleep awakening frequency and its consistency in the tracking period were not significantly correlated with the GPA for the courses taken in the sleep tracking semester (current GPA). However, both nighttime sleep awakening frequency and its consistency inversely predicted the GPA for the rest of the courses taken after that semester (future GPA). Moreover, students with more difficulty staying awake throughout the day obtained lower current and future GPAs, and students with higher inconsistency of sleep quality obtained lower future GPA. Together, these findings highlight the importance of nighttime sleep awakening frequency and consistency in predicting future academic performance, and emphasize the necessity of assessing the consistency of sleep measures in future studies.

“…In the extant literature, most studies investigating the relation between sleep and academic performance used averages of sleep measures in a period as indexes in data analysis and interpretation [41,42,48,49,[52][53][54]. Beyond these traditional sleep measures, sleep consistency or variability has been receiving more and more attention in recent years [41,43,44,53,[55][56][57][58]. Consistency of a sleep measure is usually estimated by standard deviation or standard error of the mean in a period (e.g., a few weeks), where a higher value denotes lower consistency or high variability.…”
