“…The role of sleep patterns in the development of obesity has been the subject of much investigation. Most prior studies have demonstrated an association between short sleep duration and the presence or development of obesity in children . The mechanisms underlying this association are not fully understood, but it is thought that short sleep duration may affect leptin and ghrelin secretion, increase energy consumption and alter timing of eating, all leading to increased weight .…”

“…Most prior studies have demonstrated an association between short sleep duration and the presence or development of obesity in children. (6)(7)(8)(17)(18)(19)(20) The mechanisms underlying this association are not fully understood, but it is thought that short sleep duration may affect leptin and ghrelin secretion, increase energy consumption and alter timing of eating, all leading to increased weight. (8) Furthermore, sleep deprivation may actually alter an individual's response to diet therapy such that lack of sleep decreases the efficacy of decreased caloric intake for weight loss.…”

“…Prior meta‐analysis including more than 30 000 children found a pooled odds ratio for short sleep duration and obesity of 1.8 (CI 1.4 to 2.4) . A more recent meta‐analysis of prospective studies similarly found an increased odds of obesity among children with short sleep duration, but geographical location also explained variability in effect size across studies . Furthermore, sleep schedule characteristics beyond sleep duration may play an important role in the sleep–obesity association, such as an evening chronotype or variable sleep schedules between weekday and weekend .…”

“…Future research should study the effects of interventions aiming at the reduction of sedentary behaviour among overweight and obese children on sedentary time. In addition, further study is necessary on sleep duration, which is another behavioural cue that could be an alternative intervention strategy because short sleep duration has been found to be related to obesity in children .…”

Effectiveness of interventions on physical activity in overweight or obese children: a systematic review and meta‐analysis including studies with objectively measured outcomes

et al. 2017

There is no consensus on interventions to be recommended in order to promote physical activity among overweight or obese children. The objective of this review was to assess the effects on objectively measured physical activity, of interventions promoting physical activity among overweight or obese children or adolescents, compared to no intervention or to interventions without a physical activity component. Publications up to December 2015 were located through electronic searches for randomized controlled trials resulting in inclusion of 33 studies. Standardized mean differences from baseline to post-intervention and to long-term follow-up were determined for intervention and control groups and meta-analysed using random effects models. The meta-analysis showed that interventions had no effect on total physical activity of overweight and obese children, neither directly post-intervention (-0.02 [-0.15, 0.11]) nor at long-term follow-up (0.07 [-0.27, 0.40]). Separate analyses by typology of intervention (with or without physical fitness, behavioural or environmental components) showed similar results (no effect). In conclusion, there is no evidence that currently available interventions are able to increase physical activity among overweight or obese children. This questions the contribution of physical activity to the treatment of overweight and obesity in children in the studied interventions and calls for other treatment strategies.

Meeting the 24‐hr movement guidelines: An update on US youth with autism spectrum disorder from the 2016 National Survey of Children's Health

The purpose of this study was to examine how adherence to the physical activity (PA), screen-time (ST), and sleep duration guidelines differ between youth with autism spectrum disorder (ASD) and youth with typical development (TD). A secondary objective was to assess how PA, ST, and sleep duration varied among youth with ASD by age and ASD severity. Utilizing the 2016 National Survey of Children’s Health data, parental reports of time spent by youth in PA, ST, and sleep were used to determine adherence to the 24-hr movement guidelines for 1008 youth with ASD and 34 489 youth with TD. Multivariate logistic regression analyses determined that children with ASD were less likely to meet the guidelines for PA, ST, and sleep duration, and adolescents with ASD were less likely to meet the guidelines for PA and ST than participants with TD. Furthermore, logistic regression analyses determined adolescents with severe ASD to be less likely to meet the sleep guideline compared to adolescents with mild ASD. Overall, youth with ASD were significantly less likely to adhere to all three guidelines. The findings highlight the breadth of health behaviors that require intervention to counteract the poorer health status among youth with ASD.
