&quot;The American Academy of Pediatrics strongly supports the efforts of school districts to optimize sleep in students and urges high schools and middle schools to aim for start times that allow students the opportunity to achieve optimal levels of sleep (8.5-9.5 hours) and to improve physical (eg, reduced obesity risk) and mental (eg, lower rates of depression) health, safety (eg, drowsy driving crashes), academic performance, and quality of life.&quot;

&quot;Insufficient sleep in adolescents has been shown to be associated with a wide variety of adverse outcomes, from poor mental and physical health to behavioral problems and lower academic grades. However, most high school students do not get sufficient sleep. Delaying school start times for adolescents has been proposed as a policy change to address insufficient sleep in this population and potentially to improve students' academic performance, reduce engagement in risk behaviors, and improve health. &quot;

&quot;Survey-weighted multivariate regression modeling was used to investigate associations between school start times, sleep duration, and mental health. Schools with late start times (≥8:30 a.m.) saw 32.2% (95% Confidence Interval: 29.5-35.0) of students sleeping 8 h or more relative to 23.2% (22.0-24.4) in schools with very early start times (&lt;8:00 a.m.). For every 15 min later school start time, students' sleep duration was 4.6 (3.4-5.9) min longer. Students attending schools with very early start times had 1.10 (0.95-1.27) times the odds of attempting suicide compared to those attending schools with later start times, while students at schools with early starts (8:00-8:29 a.m.) were associated with 1.11 (0.98-1.27) times the odds.&quot; and &quot;Schools with start times before 8:30 a.m. had 10-11% higher odds of students attempting suicide compared to schools with late start times, though these differences were not statistically significant. Student mental health should continue to be investigated when assessing the potential impacts of delayed school start times. &quot;
