A study (# 0312) that will be presented later this morning as a poster found that reports of better sleep across both the weekdays and the weekend appear to be positively associated with educational success.
The study involved 56 students between 14 and 18 years of age. Each of them had complaints of daytime sleepiness and/or insufficient sleep at night.
Although higher sleep quality and sleep efficiency tended to be related to higher overall grades, specific subjects were related to different sleep measures. Higher math scores were related to fewer awakenings, less time in bed, higher sleep efficiency and better sleep quality. Higher English scores were associated with fewer awakenings during the night, and both English and history scores were associated with less difficulty awakening in the morning.
Another study (#0161) presented yesterday reported that being a “night owl” or “evening type” is associated with lower academic performance in college and a decline in academic performance from high school to college.

Teen Bedtimes Associated with Suicide, Depression & Grades
Two studies being presented as posters later this morning examine the negative impact of late bedtimes on teens.
One study (#1064) suggests that parental-mandated bedtimes could help protect teens from depression and suicidal thoughts by lengthening sleep duration. Results show that adolescents with parental-mandated bedtimes at midnight or later were 25 percent more likely (adjusted odds ratio 1.25) to suffer from depression and 20 percent more likely (adjusted odds ratio 1.20) to have suicidal ideation compared with adolescents who had parental-mandated bedtimes of 10 p.m. or earlier. Multivariate models show that sleep duration may have acted as a mediator of these associations; thus short sleep may be a risk factor for depression and suicidal ideation.
Another study (#0161) shows that being a “night owl” or “evening type” – preferring to go to bed late at night and wake up later in the day – is associated with lower academic performance in college and a decline in academic performance from college to high school. Results indicate that evening types had significantly lower first year college GPA (2.84) than “morning types” and “intermediate types” (3.18). They also slept on average 41 minutes less on school nights. For all students, “sleep hygiene” was related to academic performance.
