MedicalResearch.com: What is the background for this study? What are the main findings?
Response: Approximately 90% of high-school aged adolescents get either
insufficient sleep during school nights or barely meet the required
amount of sleep (ie, 8–10 hours) expected for healthy functioning.(1)
In fact, sleep problems and insufficient sleep are so pervasive for
adolescents that they could be considered an epidemic due to their
adverse impact on adolescent mental and physical health.(2–5)
As a result,addressing insufficient adolescent sleep represents a critical
point of study and intervention. The growing body of evidence suggests
that later school start times (SST), 8:30 AM or later as recommended
by the American Academy of Pediatricians,6 convey
multiple benefits on adolescents, including improved sleep, better
mental and physical health, and improved academic outcomes.(7–10)
This research, however, has focused on the direct effects of delaying
school start times, or specifically how moving SST back directly predicts changes
in an outcome (eg, mental health, academic achievement). This
type of analysis precludes examining the important role that SST
might play as a condition or context under which other sleeprelated
processes take place. For instance, earlier school start times might exacerbate
the impact of sleep-related processes on adolescent behavioral
health outcomes. Thus, incorporating school start times as a larger contextual variable
that might moderate models of sleep and adolescent functioning
represents a gap in the literature and a unique opportunity to advance
conceptual models. Accordingly, the current study examines
the moderating role of school start times on the associations between sleep hygiene,
sleep quality, and mental health.
