WHAT'S KNOWN ON THIS SUBJECT:Sleep problems are common in school-aged children and might compromise the function of children and parents and contribute to a poor transition to school, which can result in later academic difficulties. Improvement of child sleep through brief behavioral strategies might improve the school transition. WHAT THIS STUDY ADDS:Large-scale screening of new school entrants for sleep problems, followed by a targeted behavioral intervention, was demonstrated to be feasible and was beneficial for short-to medium-term child psychosocial outcomes. Larger effectiveness trials are needed to confirm the public health benefits of these interventions. abstract OBJECTIVE: To determine the feasibility of screening for child sleep problems and the efficacy of a behavioral sleep intervention in improving child and parent outcomes in the first year of schooling. METHODS:A randomized controlled trial was nested in a population survey performed at 22 elementary schools in Melbourne, Australia. Intervention involved 2 to 3 consultations that covered behavioral sleep strategies for children whose screening results were positive for a moderate/severe sleep problem. Outcomes were parent-reported child sleep problem (primary outcome), sleep habits, psychosocial health-related quality of life, behavior, and parent mental health (all at 3, 6, and 12 months) and blinded, face-to-face learning assessment (at 6 months). RESULTS:The screening survey was completed by 1512 parents; 161 (10.8%) reported a moderate/severe child sleep problem, and 108 of 136 (79.2% of those eligible) entered the trial. Sleep problems tended to resolve more rapidly in intervention children. Sleep problems affected 33% of 54 intervention children versus 43% of 54 control children at 3 months (P ϭ .3), 25.5% vs 46.8% at 6 months (P ϭ .03), and 32% vs 33% at 12 months (P ϭ .8). Sustained sleep-habit improvements were evident at 3, 6, and 12 months (effect sizes: 0.33 [P ϭ .03]; 0.51 [P ϭ .003]; and 0.40 [P ϭ .02]; respectively), and there were initial marked improvements in psychosocial scores that diminished over time (effect sizes: 0.47 [P ϭ .02]; 0.41 [P ϭ .09]; and 0.26 [P ϭ .3]; respectively). Better prosocial behavior was evident at 12 months (effect size: 0.35; P ϭ .03), and learning and parent outcomes were similar between groups.CONCLUSIONS: School-based screening for sleep problems followed by a targeted, brief behavioral sleep intervention is feasible and has benefits relevant to school transition.

“…As short sleep duration in children has been related to other adverse effects, for example poor school and cognitive performance, 31,32 increasing the hours of sleep can have multiple benefits. Sleep duration might be a good point of entry for promoting and discussing a healthier lifestyle and weight in children and the role of parents in this.…”

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] ...

“…As summarized by Owens et al (2013), ''the cortical and brain stem regions involved in the regulation of arousal and attention and the most sensitive to sleep deprivation are also among the major sites implicated in the pathophysiology of ADHD'' (p. 555). In the frontal lobes, the PFC shows the greatest change as individuals transition from waking to sleeping states (Braun et al 1997) and is thus particularly vulnerable to sleep loss (Curcio et al 2006;Muzur et al 2002). As noted above, the PFC is also implicated in risk taking behaviors (Telzer et al 2013).…”

Sleep problems in adolescence have been identified as an international public health issue. Over the past few decades, notable advances have been made in our understanding of the patterns and consequences of sleep in adolescence. Despite these important gains, there is much about the role of sleep in adolescence that remains to be understood. This Special Issue brings together studies that examine sleep as it specifically pertains to adolescent development and adjustment. In this introductory article, we argue for the importance of grounding the study of sleep and adolescence in developmental science and a developmental psychopathology framework. First, a review of the literature is used to outline a biopsychosocial and contextual model of sleep in adolescence. Second, attention-deficit/hyperactivity disorder (ADHD) is used as an exemplar of the proposed model given the pervasiveness of sleep problems among youth with ADHD and the likelihood that sleep problems and ADHD symptoms are interconnected in complex ways. Finally, a brief introduction to the empirical articles included in the Special Issue is provided, with particular attention given to how these articles fit within the proposed biopsychosocial and contextual model. Along with the framework proposed in this article, the studies included in this Special Issue advance the current literature and point to critical directions for future research.
