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 ...

“…Scientific literature generally states that humans spend about one-third of their time sleeping 2 . On the other hand, studies have shown that sleep time has decreased in different countries [3][4][5] and insomnia is the most common sleep disorder in young and middle-aged adults 6 . Recently, studies have shown that sleep disorders in adults have been associated with a large variety of diseases, such as obesity, arterial hypertension, dyslipidemia, and diabetes mellitus (DM) [7][8][9] , as well as increased cardiovascular morbidity/ mortality 10,11 .…”

-Aim:The aim of this longitudinal study was to analyze the relationship between sleep disorder and intimamedia thickness. Method: Baseline measurements included carotid intima-media thickness, assessed by an ultrasound device; questionnaires about sleep and other behavioral variables; physical activity was measured by pedometer; body fatness was estimated by Dual-Energy X-ray Absorptiometry; fasting glucose, lipid profile and C-reactive protein were collected. Results: The occurrence rate of sleep-related disorders was 47% (95%CI= 37.2%-56.7%). Carotid intimamedia thickness was related to symptoms of insomnia (r= 0.328 [0.141 to 0.493]) and, after adjustments for potential confounders, the relationship between carotid intima-media thickness and insomnia remained statistically significant (β= 0.121 [95%CI= 0.017; 0.225]). Conclusions: In young adults, sleep disorder was significantly related to premature increase in carotid intima-media thickness.

PurposeWe aimed to investigate longitudinal associations between sleep duration and cardiorespiratory fitness, in adolescents.MethodsSleep duration was self‐reported and cardiorespiratory fitness was assessed by the 20 m shuttle run test, both at baseline and follow‐up (2‐year follow‐up). Participants were 734 Northern Portuguese adolescents (349 girls), aged 14.6 ± 1.8 years, from the LabMed study.ResultsSignificant decreases were found between baseline and follow‐up for sleep duration, whereas for cardiorespiratory fitness there was an increase. Adolescents with short sleep duration at baseline had lower cardiorespiratory fitness at follow‐up, comparing to those meeting the sleep guidelines (odds ratio [OR] = 0.506, 95% confidence interval [CI]: 0.326–0.785; p = .002 for whole week; OR = 0.597, 95% CI: 0.407–0.875; p = .008 for weekdays). Girls who were short sleepers at baseline had lower odds of having a healthy cardiorespiratory fitness at follow‐up, comparing to those meeting the sleep guidelines (OR = 0.311, 95% CI: 0.158–0.613; p < .001 for whole week; OR = 0.469, 95% CI: 0.262–0.838; p = .011 for weekdays). No significant associations between sleep duration and cardiorespiratory fitness were found for boys.DiscussionThere was a significant longitudinal association between short sleep duration and lower cardiorespiratory fitness levels, particularly in girls. Future interventions targeting adolescents' sleep duration should acknowledge behavioral differences between genders, as well as different behaviors adopted by boys ang girls, specifically on weekends.
