Insufficient sleep, poor sleep quality and sleepiness are common problems in children and adolescents being related to learning, memory and school performance. The associations between sleep quality (k=16 studies, N=13,631), sleep duration (k=17 studies, N=15,199), sleepiness (k=17, N=19,530) and school performance were examined in three separate meta-analyses including influential factors (e.g., gender, age, parameter assessment) as moderators. All three sleep variables were significantly but modestly related to school performance. Sleepiness showed the strongest relation to school performance (r=-0.133), followed by sleep quality (r=0.096) and sleep duration (r=0.069). Effect sizes were larger for studies including younger participants which can be explained by dramatic prefrontal cortex changes during (early) adolescence. Concerning the relationship between sleep duration and school performance age effects were even larger in studies that included more boys than in studies that included more girls, demonstrating the importance of differential pubertal development of boys and girls. Longitudinal and experimental studies are recommended in order to gain more insight into the different relationships and to develop programs that can improve school performance by changing individuals' sleep patterns.

    • "A growing body of literature indicates that poor sleep functioning has important implications for adjustment and adolescent health. Poor sleep functioning is linked to daytime dysfunction (Wolfson & Carskadon, 1998), impaired executive function (Anderson, Storfer-Isser, Taylor, Rosen, & Redline, 2009), reduced learning ability (Curcio, Ferrara, & De Gennaro, 2006), and poor school performance (Dewald, Meijer, Oort, Kerkhof, & Bögels, 2010). It has also been implicated in an array of poor health behaviors (Chen, Wang, & Jeng, 2006) and negative health outcomes (Javaheri, Storfer-Isser, Rosen, & Redline, 2008; Snell, Adam, & Duncan, 2007).

    ABSTRACT: Despite the importance of parenting practices for adolescent adjustment, parenting correlates of adolescent sleep functioning remain understudied. This study delineated patterns of sleep functioning in a sample of ethnically diverse, low-income, adolescents and examined associations among three types of parenting practices (parental involvement, parent-child conflict, and parental control) and adolescent sleep functioning (difficulties initiating sleep and maintaining sleep, and sleep duration). Adolescents (N = 91, 11-19 years old) self-reported on sleep functioning and parenting practices. Results showed that in the preceding month, 60.5% of adolescents had difficulties initiating sleep and 73.6% had difficulties maintaining sleep. Most adolescents slept 8 or more hours per night, but 30.7% slept less than 8 hours. Latino adolescents slept longer and had fewer difficulties maintaining sleep than non-Latino. High school students had fewer difficulties maintaining sleep than their middle school counterparts; conversely, older adolescents experienced shorter sleep duration than younger ones. Adolescents whose parents had post-secondary education had shorter sleep duration than those whose parents had not graduated from high school. Parental control was correlated with fewer difficulties initiating sleep, whereas parent-child conflict was correlated with more difficulties maintaining sleep. There were no parenting correlates of sleep duration. Latino adolescents had better sleep profiles than non-Latino ones. Regression analyses showed that parental control and parent-child conflict were associated with adolescent sleep functioning across ethnicities. Results suggest that parenting practices, as well as demographic characteristics, are associated with adolescent sleep functioning and should be taken into account in interventions aimed at improving sleep functioning among adolescents.

    • "A recent population-based study from 2012 showed that adolescents aged 16–19 receive less than 6.5 h of sleep per night, and nearly one in five adolescents fulfil the DSM-5 diagnostic criteria for insomnia disorder (Hysing et al., 2013). Adolescent sleep problems have been linked to both higher rates of depressive symptoms (Sivertsen et al., 2014), poor academic performance (Dewald et al., 2010), as well as increased risk for school non-attendance (Hysing et al., 2014). Similarly, alcohol and illicit drug use among adolescents have been linked to a range of deleterious consequences, including higher risk of frequent intoxication, abuse and dependence, in addition to violence, injuries (Jacobs et al., 2001), and several adverse health outcomes (Ellickson et al., 2003; Roebuck et al., 2004; Skogen et al., 2014; Townsend et al., 2007).

    ABSTRACT: Changes in sleep patterns and increased substance involvement are common in adolescence, but our knowledge of the nature of their association remains limited. The aim of this study was to examine the association between several sleep problems and sleep behaviours, and use and misuse of alcohol and illicit drugs using data from a large population-based sample. A large population-based study from Norway conducted in 2012, the youth@hordaland study, surveyed 9328 adolescents aged 16-19 years (54% girls). Self-reported sleep measures provided information on sleep duration, sleep deficit, weekday bedtime and bedtime difference and insomnia. The main dependent variables were frequency and amount of alcohol consumption and illicit drug use, in addition to the presence of alcohol and drug problems as measured by CRAFFT. The results showed that all sleep parameters were associated with substance involvement in a dose-response manner. Short sleep duration, sleep deficit, large bedtime differences and insomnia were all significantly associated with higher odds of all alcohol and drug use/misuse measures. The associations were only partly attenuated by sociodemographics factors and co-existing symptoms of depression and ADHD. To the best of our knowledge, this is the first population-based study to examine the association between sleep, and alcohol and drug use, by employing detailed measures of sleep behaviour and problems, as well as validated measures on consumption of alcohol and illicit drug use. The findings call for increased awareness of the link between sleep problems and alcohol and drugs use/misuse as a major public health issue. Copyright © 2015 Elsevier Ireland Ltd.

Similar observations have been made in other adolescent cohorts [1] [2] [3], indicating that sleep problems among adolescents have reached an epidemic level in our modern societies. One common behavior among adolescents that may compromise their regular good night's sleep is the use of the Internet in periods when adolescents should sleep, i.e. during the night.Supporting this view, we demonstrate that adolescents with Table 2 Association of self-reported sleep disturbance and short sleep duration with academic failure.

    ABSTRACT: Objective: To examine associations of self-reported sleep disturbance and short sleep duration with the risk for academic failure. Methods: A cohort of ~40,000 adolescents (age range: 12–19 years) who were attending high school grades 7, 9, and 2nd year of upper secondary school in the Swedish Uppsala County were invited to participate in the Life and Health Young Survey (conducted between 2005 and 2011 in Uppsala County, Sweden). In addition to the question how many subjects they failed during the school year (outcome variable), subsamples of adolescents also answered questions related to subjective sleep disturbance (n = 20,026) and habitual sleep duration (n = 4736) (exposure variables). Binary logistic regression analysis was utilized to explore if self-reported sleep disturbances and habitual short sleep duration (defined as less than 7–8 h sleep per night) increase the relative risk to fail subjects during the school year (controlled for possible confounders, e.g. body-mass-index). Results: Adolescents with self-reported sleep disturbances had an increased risk for academic failure (i.e., they failed at least one subject during the school year; OR: boys, 1.68; girls, 2.05, both P < 0.001), compared to adolescents without self-reported sleep disturbances. In addition, adolescents who reported short sleep duration on both working and weekend days were more likely to fail at least one subject at school than those who slept at least 7–8 h per night (OR: boys, 4.1; girls, 5.0, both P < 0.001). Conclusion: Our findings indicate that reports of sleep disturbance and short sleep duration are linked to academic failure in adolescents. Based on our data, causality cannot be established.
