“…One possible explanation is that prolonged sleep duration reflects compensation for poor-quality and/or interrupted sleep, which may be more common among overweight and obese person. A study showed that, compared with normal-weight children, overweight and obese children had less slow-wave sleep (SWS), which plays a major role in body restorative processes and energy metabolism [ 43 ].…”

BackgroundObesity has been identified as a major risk factor for a large number of chronic diseases. Understanding factors related to adolescent obesity is critical for prevention of chronic diseases. The associations between sleep duration and obesity among adolescents in the existing literature are controversial. Our study was designed to determine the prevalence of short sleep duration, and assess the association of sleep duration and obesity, among middle and high school students in Zhejiang, China.Methods18,403 Students in 442 schools were recruited and surveyed using an anonymous, self-administered questionnaires. Weighted multivariable logistic regression models were used for data analyses.ResultsThe mean (SD) age of the students was 15.9 (1.8) years. 49.7% of students were girls. The mean (SD) height and weight were 166.2 (8.5) cm and 54.6 (11.1) kg, respectively. The overall prevalence of obesity and overweight were 3.4% (95% CI: 3.0–3.8) and 7.8% (95% CI: 7.4–8.3), respectively. The overall prevalence of short sleep duration among students was 66.0% (95% CI: 63.8–68.1), higher among girls than boys (69.8% vs. 62.1%) (P < 0.0001). The figures for middle school, academic high school, and vocational high school were 59.0, 82.4 and 59.7%, respectively (P < 0.0001). As compared with girls who sleep 8 h per day (reference), the odds ratios (95% CI) of obesity for girls who sleep < 7 h, 7 h, 9 h and ≥ 10 h were 1.97 (1.15–3.38), 1.90 (1.18–3.04), 1.38 (0.86–2.20) and 2.12 (1.22–3.67) respectively, after adjustment for socio-demographic status, lifestyle factors, and mental health. The corresponding figures among boys were 1.45 (0.97–2.16), 1.13 (0.81–1.57), 1.25 (0.89–1.74), and 1.12 (0.81–1.54), respectively.ConclusionsInsufficient sleep is prevalent among students in Zhejiang China. A U-shaped relationship was found between sleep duration and obesity risk among girls, with the lowest risk among those who slept for 8 h, but not among boys. Adequate sleep duration may be an important component of obesity prevention initiatives among adolescents.Electronic supplementary materialThe online version of this article (10.1186/s12986-018-0285-8) contains supplementary material, which is available to authorized users.

“…Apart from obesity, overweight could also be a risk factor for negative health consequence [ 13 ]; however, few studies have mentioned the effect of short sleep on overweight risk. A link between no-rapid eye movement sleep and overweight was suggested, but the research has a relatively small sample size [ 14 ]. Moreover, child overweight, as the intermediate state between normal weight and obesity, could be reversed, which means it is worthy of exploration as an independent negative outcome.…”

BackgroundThe relationship between sleep duration and overweight risk remains unexplored among Chinese children. This study aims to evaluate this association in a national investigation with school-aged population.MethodsThere were 18,302 normal weight children in this Chinese national study which conducted during 2013–2014 included in the research. Anthropometric measurements were performed both at baseline and after 6–9 month. Sleep duration, physical activity, food intake and social economic information were collected by self-report questionnaire. Overweight was defined according to the updated Chinese criterion. Cox regression was used to evaluate the relationships between sleep duration and overweight incidence with multivariable adjusted.ResultsIn total, there were 443 new overweight cases recorded at the end of observation. Overweight incidence with greater than 9 h (long sleep duration, LSD), 7 to 9 h (middle sleep duration, MSD), and less than 7 h of sleep (short sleep duration, SSD) were 2.7, 3.1 and 3.3% respectively. Stratified by gender and compared with LSD, the hazard ratio (HR) of overweight for females with MSD was 1.60 (95% CI: 1.02–2.52). Stratified by age and gender, the HR in the group of MSD was 2.13 (1.20–3.77) in female aged 6–10 years and 0.24 (0.06–0.93) in female aged 15–17 years.ConclusionThe association between short sleep duration and overweight is age- and gender dependent. In group of small age and elder age, girls’ adiposity states are independently associated with sleep duration. Sleep recommendation is a potential preventive action for overweight/obesity among girls.

“…Most national and international guidelines focus on recommendations for sleep duration, since prior research has demonstrated that insufficient sleep duration during adolescence is associated with a variety of cognitive, psychological, and health risks, including higher body mass index (BMI) [8–10], greater body fat [11], and increased insulin resistance [12]. However, emerging evidence suggests that sleep quality [13–15] and timing may also affect adolescent cardiometabolic risk factors [7]. For instance, later bedtimes are associated with greater BMI [10, 16], body fat [11] and higher systolic blood pressure in children and adolescents [17].…”

24Background 25 Sleep and physical activity are modifiable behaviors that play an important role in preventing 26 overweight, obesity, and metabolic health problems. Studies of the association between 27 concurrent objective measures of sleep, physical activity, and metabolic risk factors among 28 adolescents are limited. 29 Objective 30The aim of the study was to examine the association between metabolic risk factors and 31 objectively measured school day physical activity and sleep duration, quality, onset, and 32 variability in adolescents. 34 We measured one school week of free-living sleep and physical activity with wrist actigraphy 35 in 252 adolescents (146 girls), aged 15.8±0.3 years. Metabolic risk factors included body mass 36 index, waist circumference, total body and trunk fat percentage, resting blood pressure, and 37 fasting glucose and insulin levels. Multiple linear regression adjusted for sex, parental 38 education, and day length was used to assess associations between metabolic risk factors and 39 sleep and activity parameters. 33 Materials and Methods40 Results 41On average, participants went to bed at 00:22±0.88 hours and slept 6.2±0.7 hours/night, with 42 0.83±0.36 hours of awakenings/night. However, night-to-night variability in sleep duration 43 (0.87±0.57 hours) and bedtime (0.79±0.58 hours) was considerable. Neither average sleep 44 duration nor mean bedtime was associated with any metabolic risk factors. However, greater 45 night-to-night variability in sleep duration was associated with higher total body (β=1.9±0.9 3 46 %/h, p=0.03) and trunk fat percentage (β=1.6±0.7 %/h, p=0.02), poorer sleep quality (more 47 hours of awakening) was associated with higher systolic blood pressure (β=4.9±2.2 mmHg/h, 48 p=0.03), and less physical activity was associated with higher trunk fat percentage (p=0.04) and 49 insulin levels (p=0.01). 50 Conclusion 51Greater nightly variation in sleep, lower sleep quality, and less physical activity was associated 52 with a less favorable metabolic profile in adolescents. These findings support the idea that, 53 along with an adequate amount of sleep and physical activity, a regular sleep schedule is 54 important to the metabolic health of adolescents. 55 56 57 58 59 60 61 62 63 64 65 66 67 68 69 4 70 71The prevalence of overweight in the world has nearly tripled from 1975-2016, with over 72 39% of adults and 18% of children and adolescents being overweight or obese [1]. Greater total 73 body and central adiposity is associated with increased risk of cardio-metabolic comorbidities, 74 such as hypertension and diabetes [2, 3]. Prevalence of metabolic syndrome is high among 75 obese children and adolescents and increases with higher central obesity [4]. Along with diet, 76 sleep and physical activity have been identified as important modifiable risk factors implicated 77 in the development of overweight, obesity, and metabolic health problems [5]. 78 The importance of adequate sleep for health and daily functioning in adolescents is well 79 established [...
