Adolescent sleep insufficiency one year after high school^☆

Abstract

This study captures sleep habits of adolescents one year after high school regardless of school and/or working status. Implications and future directions are discussed.

Relationships between Extra-School Tutoring Time, Somatic Symptoms, and Sleep Duration of Adolescent Students: A Panel Analysis Using Data from the Korean Children and Youth Panel Survey

“…Interestingly, parental education level was associated with shorter sleep duration [51]. This may be due to Korean parents' extraordinary interest in their children's academic achievement and parental involvement including private tutoring time, which may be related to sleep alterations in adolescent students [42,43,52].…”

<p>Sleep Quality of Students from Elementary School to University: A Cross-Sectional Study</p>

“…The numerous health and academic-related consequences of sleep problems make sleep, particularly during emerging adulthood, a public health concern. 14 College students experience unique challenges at the beginning of campus life (eg experiencing an unfamiliar environment, being responsible for oneself for the first time, academic stress, and living in a dormitory with students from different regions and cultures), all of which influence, or even heavily change, their sleep styles and sleep quality. The prevalence of poor sleep quality and the average PSQI score in our study were similar to those reported in previous studies of Chinese college students.…”

“… 41 Adolescent behavioral habits, including sleep, tend to persist into adulthood. 14 However, high school students in China are among the most sleep-restricted population. Despite the increasing evidence of the detrimental effects of sleep loss in students, little has considered their exact school stages as modifiers of sleep patterns.…”

“…For example, a meta-analysis of the sleep patterns of adolescents worldwide found that approximately 45% of adolescents in grades 6 to 12 were affected by insufficient sleep. 14 Chronic exposure to low-quality sleep among adolescent students is related to overweight, poor self-rated health, depression symptoms, and poor well-being, 10 , 11 and can increase the risk of self-harm behavior and even suicide attempts. 15 Meanwhile, regarding university students, unfavorable sleep status is usually closely associated with short sleep duration and negative impacts on social relationships.…”

Seasonal variability of the vitamin D effect on physical fitness in adolescents

“…To investigate potential determinants of physical fitness performance (main outcome), we fitted a series of simple (i.e., one independent variable at a time) and multiple (i.e., two or more independent variables simultaneously included in the same model) regression models. In detail, the fitted ordinary least squares regression models included the physical fitness performance score (continuous) as the dependent variable and the following independent variables: body fat percentage, mid-upper arm circumference, astronomical season, site and level of recreational physical activity, frequency of alcohol consumption, frequency of soda consumption, frequency of snack consumption, frequency of fruit consumption, smoking, adequacy of sleeping hours (sufficient ≥ 7 or insufficient < 7 h) 50 , frequency and hours spent per session of gaming/TV-watching, hemoglobin, creatinine and total 25-OH-vitamin D. The best multiple (main-effects) model was selected using the Akaike Information Criterion (AIC) combined with clinical plausibility. Given that our main focus was on vitamin D, we also examined all the regression models presenting pairwise interaction terms, including total 25-OH-vitamin D, as one of the two variables.…”
