“…Recent studies have reported that short sleep duration (< 9 h for adolescents) affects academic achievement, motivation and attention (Merikanto et al, 2013;Perez-Lloret, 2013;Stea et al, 2014). Results obtained in the present study indicated that time in bed on weekdays was positively related to GPA.…”

Adolescents in high school suffer from circadian misalignment, undersleeping on weekdays and oversleeping on weekends. Since high schools usually impose early schedules, adolescents suffer from permanent social jetlag and thus are a suitable population to study the effects of social jetlag on both academic and cognitive performance. In this study, 796 adolescents aged 12 to 16 reported information about their sleep habits, morningness-eveningness, cognitive abilities and grade point average.Time in bed on both weekdays and weekends were not related to cognitive abilities, and only time in bed on weekdays was related to academic achievement. Social jetlag was negatively related to academic achievement, cognitive abilities (except for vocabulary and verbal fluency abilities) and general cognitive ability (g), whereas morningnesseveningness was slightly positively related to academic achievement and marginally negatively related to inductive reasoning. Results separated by sex/gender indicated that social jetlag may be more detrimental to girls' performance, as it was negatively related to a greater number of cognitive abilities and grade point average.

Abstract:The objective of this systematic review was to examine the relationships between objectively and subjectively measured sleep duration and various health indicators in children and youth aged 5-17 years. Online databases were searched in January 2015 with no date or study design limits. Included studies were peer-reviewed and met the a priori-determined population (apparently healthy children and youth aged 5-17 years), intervention/exposure/comparator (various sleep durations), and outcome (adiposity, emotional regulation, cognition/academic achievement, quality of life/well-being, harms/injuries, and cardiometabolic biomarkers) criteria. Because of high levels of heterogeneity across studies, narrative syntheses were employed. A total of 141 articles (110 unique samples), including 592 215 unique participants from 40 different countries, met inclusion criteria. Overall, longer sleep duration was associated with lower adiposity indicators, better emotional regulation, better academic achievement, and better quality of life/well-being. The evidence was mixed and/or limited for the association between sleep duration and cognition, harms/injuries, and cardiometabolic biomarkers. The quality of evidence ranged from very low to high across study designs and health indicators. In conclusion, we confirmed previous investigations showing that shorter sleep duration is associated with adverse physical and mental health outcomes. However, the available evidence relies heavily on cross-sectional studies using self-reported sleep. To better inform contemporary sleep recommendations, there is a need for sleep restriction/extension interventions that examine the changes in different outcome measures against various amounts of objectively measured sleep to have a better sense of dose-response relationships.Key words: sleep duration, adiposity, body weight, emotional regulation, mental health, cognition, academic achievement, quality of life, well-being, injuries.Résumé : Cette analyse systématique a pour objectif d'examiner la relation entre la mesure objective et subjective de la durée du sommeil et d'autres indicateurs sanitaires chez des enfants et des jeunes âgés de 5 à 17 ans. En janvier 2015, une recherche est faite dans les bases de données en ligne sans contrainte de date et de devis utilisé. Les études retenues sont sanctionnées par des pairs et sont conformes aux critères a priori déterminés : la population (des jeunes apparemment en bonne santé âgés de 5 à 17 ans), l'intervention/exposition/comparaison (durées variées du sommeil) et le résultat (adiposité, contrôle des émotions, cognition/ rendement scolaire, qualité de vie/bien-être, préjudices/blessures et biomarqueurs cardiométaboliques). À cause du haut niveau d'hétérogénéité des études, on utilise des synthèses narratives. Au total, 141 articles (110 échantillons originaux) incluant 592 215 participants distincts de 40 pays différents sont conformes aux critères d'inclusion. Globalement, une plus longue durée de sommeil est associée aux indicateurs de ...

Objectives To examine associations between sleep and alcohol, amphetamine, cigarette, marijuana, and non-heroin narcotic use among US middle and high school students, trends in associations over time, and the comparative impact of select covariates on association strength. Methods Data from the 1991–2014 nationally representative Monitoring the Future study of 8th, 10th, and 12th grade US students were used to estimate standardized correlations between the frequency of getting at least 7 hours of sleep (7+ sleep) and substance use frequency while simultaneously regressing both outcomes on key covariate domains. Results As 7+ sleep frequency increased, substance use frequency significantly decreased and vice versa. Overall, association strength was inversely associated with grade. Associations were generally modest, varied across substances, and weakened over the historical period examined for 8th and 10th graders. Associations showed little variance by sex and racial/ethnic subgroups. Controlling for deviance, psychosocial, and general health covariates significantly attenuated association strength. Conclusions Among US secondary students, 7+ sleep/substance use associations were largely explained by individual deviance, psychosocial, and general health characteristics. Awareness and exploitation of these shared associations may be useful in improving substance use prevention and/or treatment efforts.
