“…Primary school children in China averaged 9.3 vs 10.2 hours of sleep compared with US children and reported daytime sleepiness. 40 Cross-sectional analysis of child journals and caregiver questionnaires for 755 children aged 8 to 11 years showed that at all ages minority boys slept significantly less compared with minority girls and all nonminority children. 8 A parent-report survey of 472 children in 1 US city showed an inverse association between socioeconomic status and both parasomnias and noisy sleep.…”

OBJECTIVE. Our goal was to identify characteristics associated with inadequate sleep for a national random sample of elementary school-aged children (6 -11 years) and adolescents (12-17 years).METHODS. Data from 68 418 participants in the 2003 National Survey of Children's Health were analyzed by using weighted bivariate and multivariate regression models. The dependent variable was report of not getting enough sleep for a child of his or her age Ն1 night of the past week. Independent variables included demographic characteristics, child health, school and other activities, and family life.RESULTS. Parents of elementary school-aged children with inadequate sleep were more likely to report that their child was having problems at school or had a father with fair or poor health. Parents of adolescents with inadequate sleep were more likely to report that their child had an atopic condition, frequent or severe headaches, a parent with less-than-excellent emotional health, or experienced frequent parental anger. Inadequate sleep in both age groups was associated with parental report that their child usually or always displayed depressive symptomatology, family disagreements involved heated arguing, or parental concern that the child was not always safe at home, at school, or in their neighborhood.CONCLUSIONS. Approximately 15 million American children are affected by inadequate sleep. Primary care providers should routinely identify and address inadequate sleep and its associated health, school, and family factors.www.pediatrics.org/cgi

“…In contrast to adults, this morning routine is usually less internalized and self-governed. Second, night-time sleep duration decreases and morning drowsiness increases across childhood and adolescence (Carskadon, 1990;Sadeh et al, 2000;Fallone et al, 2002;Liu et al, 2005). Fewer changes in sleep habits are observed among adults.…”

SummaryCompliance with awakening salivary sampling is important for precise measurement of the diurnal cortisol profile. During childhood and adolescence, developmental factors influence sampling upon awakening (awake 0 ) due to school routine, sleep/wake patterns, and age related cortisol changes. In the present study, children and adolescents' sampling compliance of awakening cortisol was evaluated using accelerometry. Children and adolescents (N = 201; 45.3% female; 8-18 years; M age = 12.68 years, SD = 2.03) participating in the Healthy Heart Project collected saliva samples, wore a tri-axle accelerometer, and completed demographic questionnaires. Intraclass correlations derived to examine awake 0 sampling compliance indicated children and adolescents were highly compliant (ICC = .98). In children, a delay in awake 0 sampling was associated with a steeper diurnal slope (β = −.23, p = .037) and greater awake 0 cortisol (β = .24, p = .024); this was not observed in adolescents. In summary, children and adolescents are compliant with awakening salivary sampling. Sampling delay, particularly in children, and time of awakening influenced measures of the diurnal cortisol profile. These findings inform future studies assessing the diurnal cortisol profile in children and adolescents.

“…With regard to socio-demographic factors, children of Caucasian ethnicity have been indicated to sleep longer than children of other ethnicities. [6][7][8][9] Age is inversely associated with sleep deprivation. 10 The role of environmental factors on sleep duration is unclear, but there are indications that the physical and socio-cultural home environment play an important role.…”

Association between sleep duration and overweight: the importance of parenting

et al. 2012

OBJECTIVE: Sleep duration has been related to overweight in children, but determinants of sleep duration are unclear. The aims were to investigate the association between sleep duration and childhood overweight adjusted for family characteristics and unhealthy behaviours, to explore determinants of sleep duration and to determine with sleep competing activities. METHOD: A cross-sectional study was carried out in 2006 among 4072 children aged 4-13 years in the city of Zwolle, The Netherlands. In these children, data were available on measured height, weight and waist circumference, and from a parental questionnaire, on socio-demographic characteristics, child's sleep duration, nutrition, physical activity and sedentary behaviour. Associations were studied in 2011 using logistic and linear regression analyses, adjusted for potential confounders. RESULTS: Short sleep duration was associated with overweight for 4-8-year-old boys (odds ratio (OR):3.10; 95% confidence interval (CI):1.15-8.40), 9-13-year-old boys (OR:4.96; 95% CI:1.35-18.16) and 9-13-year-old girls (OR:4.86; 95% CI:1.59-14.88). Among 4-8-year-old girls no statistically significant association was found. Determinants for short sleep duration were viewing television during a meal, permission to have candy without asking, not being active with their caregiver and a late bedtime. For all children, short sleep duration was strongly associated with more television viewing and computer use. CONCLUSIONS: Association between sleep duration and overweight is not explained by socio-demographic variables, drinking sugared drinks and eating snacks. Parents have a key role in stimulating optimal sleep duration. Improving parenting skills and knowledge to offer children more structure, and possibly with that, increase sleeping hours, may be promising in prevention of overweight. INTRODUCTIONOver the past decades, there has been a growing interest in the relationship between sleep duration and high body weight. A large number of studies has shown an association between reduced sleep duration and childhood overweight, especially in young children. [1][2][3] The association between short sleep duration and overweight seems to be stronger for boys than girls, 4 although not all studies have reported a gender difference. 2 Possible explanations for the association between sleep duration and overweight include the role of behavioural and hormonal factors; short sleep leaves more time for eating, particularly snacking or drinking sugared drinks, and causes alterations in appetite-regulating hormones resulting in overeating. 1,2,5 Moreover, sleepiness may result in reduced physical activity and increased sedentary behaviour. 1,2,5 Determinants of short sleep duration have not yet been fully explored. Presumably, sleep duration is influenced by a combination of socio-demographic, behavioural and environmental factors. With regard to socio-demographic factors, children of Caucasian ethnicity have been indicated to sleep longer than children of other ethnicities. [6][7][8][9] ...
