Zusammenfassung
Je früher wir Kinder und Jugendliche über den Schlaf und seine Funktionen aufklären, desto besser können wir Schlafproblemen vorbeugen und sie beheben. In diesem Beitrag wird das gesundheitspsychologische Projekt „Schulische Gesundheitsförderung zum Thema Schlaf und Gesundheit“, welches 2020 von der Universität Salzburg in Kooperation mit der Österreichischen Gesundheitskasse initiiert wurde, vorgestellt. Dieses Projekt zielt darauf ab, das im Schlaflabor gesammelte Wissen direkt in die Schulen zu tragen und dort mittels Workshops in den Alltag der Schüler*innen und Lehrer*innen zu integrieren. Wissensvermittlung und Prävention sind auch der Fokus des im Verlag edition Riedenburg erschienenen Buches „Genial im Schlaf“, welches als Basis des Schulprojektes dient und die Schüler*innen für richtiges Schlafverhalten sensibilisieren sowie im Falle von Schlafproblemen Hilfestellungen bieten soll.

Background: Obesity in children is a serious health problem with a rapidly increasing global prevalence. Children with obesity are at high risk of developing several metabolic diseases as adults. Studies show that short sleep duration is a risk factor for obesity. Short sleep duration will affect the diurnal rhythm and disrupt homeostasis and energy metabolism. This systematic review aims to determine the relationship between sleep duration and obesity in children. Methods: A systematic literature review was carried out by literature searching on PubMed and Google Scholar using the PRISMA diagram and based on the eligibility criteria in selecting literature. The study was limited to the last five years (2017-2021). Studies that met the criteria were included in the analysis. Results: There were 17 studies included in the analysis with cross sectional studies, prospective cohorts and clinical trials study designs regarding the relationship between sleep duration and obesity in children. All studies show a strong association between sleep duration and obesity in children and adolescents. The underlying mechanism is short sleep duration affects the balance of hormones controlling hunger and appetite so that appetite increases and causes excess energy intake, resulting in obesity. Children with short sleep duration are 2-4 times more prone to obesity compared to children with normal sleep duration. Conclusion: There is a significant relationship between sleep duration and obesity in children and adolescents. Adequate sleep duration is recommended to prevent obesity and the risk of metabolic and cardiovascular diseases.
... This assumption is validated by findings in the population from research by Wang, et al in China which states that students with short sleep duration have less active physical activity when compared to students with short sleep duration. 30 Physiologically, sleep duration decreases from infancy to childhood and to adolescence. Research conducted on children aged 6 to 20 years in Hong Kong, found a tendency for shorter sleep duration in high school children compared to elementary and junior high school children. ...
... This study found that sleeping for 8 hours is the minimum amount of sleep each day needed by junior high school and high school students to prevent the risk of developing obesity. 30 Other findings estimate that for every 1 hour of reduced sleep duration it is likely to increase the risk of obesity in adolescents by 80%. 18 A cross-sectional study supports that teens who sleep late are more likely to have a higher BMI when compared to teens who go to bed early. ...
In recent years, short sleep duration has been proposed and received attention as a modifiable factor of obesity. Observational studies on the relationship between sleep duration and obesity in children and adolescents in the Asian region have been carried out. This study aims to determine the relationship between short sleep duration and obesity in children and adolescents in Asia. This study used a meta-analysis method. Search for articles using the Pubmed, Proquest, Science direct and Google Scholar databases. Article search is limited to research in English, publications from 2000 to 2020 and free full text articles. Data is processed using the Revman 5.3 application. There were 12 research articles that were systematically reviewed from 1,281 identified articles. Ten of these articles were included in the meta-analysis. The results of the study proved that there was a significant relationship between short sleep duration and obesity in children and adolescents with a pooled OR of 1.15 (95% CI: 1.04-1.28), and an analysis of the age subgroup also showed the same results as the pooled OR. 1.17 (95% CI: 1.02-1.35) in the age group before 3-4 years and combined OR 1.29 (95% CI: 1.14-1.48) in children aged 6-12 years. Avoiding short sleep duration can be considered as one way to reduce the risk of obesity in children and adolescents.
... [9][10][11] Plenty of literature explored the role of sleep duration on overweight/obesity as well as the age or gender disparity in the above association, yet their findings remain inconsistent. [12][13][14] However, few overweight/obesity-focused studies paid attention to its association with breakfast habits. 15,16 Moreover, previous studies rarely attempted to examine the joint association of insufficient sleep and skipping breakfast with overweight/obesity. ...
... Finally, we performed sensitivity analyses. We examined the individual association of breakfast habit (treated as a tri-categorical variable: "never," "sometimes" and "always") and sleep duration (treated as an age-specific multi-categorical variable: six categories including "< 8 h," "8 h," "9 h," "10 h," "11" and "≥11 h" for 8-12-year-olds or five categories including "< 7 h," "7 h," "8 h," "9 h" and "≥10 h" for 13-17-year-olds, according to the international recommendation 13,24 ) with overweight or obesity. Besides, we looked at the separate and joint association of insufficient sleep and skipping breakfast with the outcome by treating BMI as a continuous variable. ...
... 40 Variety across gender may be owing to the physiological or hormone differences between girls and boys in association with obesity, which could make girls more sensitive to breakfast intake or sleep duration. 13,[41][42][43] The large sample size and data availability in a very recent year allowed us to analyse both the individual and joint association of ...
Background
Insufficient sleep and skipping breakfast are very common phenomena in China and have been proposed as possible causes of overweight/obesity, but the results of former studies remain inconsistent.
Objective
To investigate the individual and joint association of insufficient sleep and skipping breakfast with overweight/obesity among children and adolescents in Jiangsu Province, China.
Methods
Participants were 36 849 students aged 8–17 years from the 2019–2020 project “Surveillance for common disease and health risk factors among students.” Self‐reported insufficient sleep and skipping breakfast were ascertained by self‐reported sleep duration and breakfast habit. Overweight/obesity was assessed according to the gender‐ and age‐specific body mass index. We used logistic regression models to explore the association of sleep and breakfast with overweight/obesity, and stratification analyses to test age or gender differences.
Results
The overall prevalence of overweight/obesity was 33.2%. Insufficient sleep (OR = 1.09, 95% CI = 1.03–1.16) or skipping breakfast (OR = 1.14, 95% CI = 1.07–1.21) was associated with overweight/obesity. Compared to participants with ‘sufficient sleep and breakfast’, ORs were 1.25 (95% CI = 1.15–1.35) for those with ‘both insufficient sleep and skipping breakfast’. The separate and joint association of sleep and breakfast with overweight/obesity remained generally consistent across different age and gender subgroups, except that the 8–12‐year‐olds group and female students appear more susceptible.
Conclusions
Insufficient sleep and skipping breakfast were jointly associated with overweight/obesity in children and adolescents. Appropriate attention should be paid to these modifiable behaviours including sleep and breakfast in the context of the rapidly growing obesity epidemic among children and adolescents.
... Survey results also indicated that more than half of the participants (57.15%) do not reach the sleep duration recommendation by NSF [35] in the current study. The result is consistent with previous Chinese studies, in which insufficient sleep prevalence ranges from 31.3% to 66.0% [15,19,49], and higher than those studies from Western countries with 14.2% to 50.0% prevalence [16,50,51]. The differences in the prevalence of insufficient sleep may be related to the unique culture and educational system in China, where education is based on Confucian principles addressing the successful scholarship of children and adolescents [52]. ...
... Short sleep duration only increased the risk for overweight/obesity of girls after multivariable adjustment, but not for boys. This finding is in agreement with some previous Chinese studies [49,57]. Sex differences in the physiology in puberty may explain this finding. ...
Background and objective
The high prevalence of obesity is a serious problem, and sleep is considered to be a factor for obesity. This study aimed to examine the relationship between sleep duration, sleep quality, and weight status among children and adolescents in China and to explore whether the relationship between sleep duration and weight status is independent of sleep quality. Sex and age differences were also explored.
Methods
A cross-sectional research was conducted among 2019 children and adolescents (1029 boys and 990 girls) aged 8–16 years in Shanghai. An open-question was used to obtain data on sleep duration, which was categorized into the following four groups based on the age-specific National Sleep Foundation Sleep Duration Recommendations: 1) very short, 2) short, 3) recommended, and 4) long. The Pittsburgh Sleep Quality Index was used to assess sleep quality. Weight and height were measured for all participants. The variable weight status was estimated with the Chinese children and adolescent age- and sex-specific body mass index (BMI) and was categorized into overweight/obesity and normal weight.
Results
Short sleep duration (7–8 and 6–7 h for 6–13 and 14–16 years old, respectively) significantly increased odds of overweight/obesity (OR = 1.32, 95% CI: 1.06–1.64) compared with that of the recommended sleep duration (9–11 and 8–10 h for 6–13 and 14–16 years old, respectively). The relationship between the two variables existed independent of sleep quality. No significant relationship was found between sleep quality and overweight/obesity of children and adolescents. Sleep quality (OR = 1.07, 95% CI: 1.01–1.14) and short sleep duration (OR = 1.51, 95% CI: 1.06–2.13) increased the risk for overweight/obesity among girls, whereas no significant relationships between sleep duration, sleep quality, and overweight/obesity were found among boys. Short sleep duration increased the risk of overweight/obesity in children aged 8–13 years (OR = 1.34, 95% CI: 1.05–1.71), independent of sleep quality, but no significant relationships between these two variables existed for adolescents aged 14–16 years.
Conclusions
Overall, short sleep duration increased the risks of overweight/obesity in children and adolescents in China, independent of sleep quality. This relationship is significant for girls and children aged 8–13 years instead of boys and adolescents aged 14–16 years. Interventions to extend the sleep duration of children and adolescents, especially girls and children aged 8–13 years in China, are necessary to improve their weight status.
... In developed nations, short sleep duration has been well recognized as a potential contributor to pediatric obesity and demonstrated a negative linear association in several cross-sectional and longitudinal epidemiological studies [7,8,[14][15][16][17][18][19][20][21][22]. From the resource-limited settings such as China [23] and India [24], studies illustrated similar significant association between the two variables. For quite some time, most studies utilized only sleep duration as the sole measure for inadequate sleep, which is a misleading approach since sleep is multidimensional [25]. ...
... The probable reasons for not finding any significant relationship between these two variables in those studies may be due to the absence of adjusting potential confounders, recruitment of respondents only from urban schools, consideration of only total sleep duration as an independent variable, and selection of relatively smaller sample sizes (n=<300). However, the present findings are consistent with some studies from Asian countries like China [23] and India [24] that reported significant association between sleep duration and overweight/obesity. The Indian study signified inadequate sleep duration with higher odds of adolescents being overweight or obese (OR=1.56, ...
... The Indian study signified inadequate sleep duration with higher odds of adolescents being overweight or obese (OR=1.56, 95% CI=1.12 -2.15), [24] whereas the Chinese study found a U-shaped association between sleep duration and the risk of obesity among their youths [23]. Several studies conducted in some developed countries such as in Turkey, [42] Saudi Arabia, [43] USA, [18] Portugal, [19] Australia [20] and Canada [21] also reported significant inverse associations between sleep duration and overweight or obesity. ...
Abstract Background Sleep deprivation is widely recognized as a potential contributor to childhood obesity. However, few studies have addressed this issue in low-income settings. The aim of this study was to determine the association of both sleep duration and sleep quality with overweight/obesity among adolescents of Bangladesh. Methods A cross-sectional study was conducted in four randomly selected schools in Gazipur, Bangladesh, from May to August 2019. Using a self-administered semi-structured questionnaire, data on sleep duration and sleep quality were collected from 1,044 adolescents between 13 and 17 years of age. The body mass indices of the study participants were evaluated using their objectively-assessed anthropometric measurements (weight and height). Multilevel logistic regression was used for data analysis. Results The prevalence of underweight, overweight and obesity in adolescents in this study were 14.9, 18 and 7.1%, respectively. More than 15% of the students reported sleep disturbance and poor sleep quality. After adjusting for confounders, reduced (
... In other words, when calorie consumption is less than calorie intake, the excess calories are retained in the body, leading to obesity. However, sleep may also be a potential cause of obesity [2][3]. Many cross-sectional studies in different countries have shown that short sleep durations in adults are signi cantly associated with obesity [4][5][6]. ...
Background: Previous studies examining the association of sleep duration with general obesity among adults are from western countries, where the patterns of adulthood sleep (shorter or longer sleep durations) and abdominal obesity may be different from Taiwan. Furthermore, the negative associations between sleep duration and abdominal obesity among adults in the existing literature remain controversial. The purpose of this study was to investigate the association between sleep duration and risk of abdominal obesity in Taiwanese adults.
Methods: This was a cross-sectional study conducted on 58,238 adults who participated in Taiwan’s National Physical Fitness Survey 2014-2015. Data from a standardized structured questionnaire and anthropometric measures were analyzed. Individuals’ sleep durations were categorized as very short (≤5.0 h), short (5.1–6.0 h), optimal (6.1–7.0 h), long (7.1–8.0 h), or very long (>8.0 h). Abdominal obesity was classified according to waist circumference (WC) ≥ 90 cm for men and WC ≥ 80 cm for women. Multiple logistic regression analysis was performed to evaluate the risk factors for abdominal obesity.
Results: The multiple logistic regression, using the optimal sleep duration as a baseline, indicated significant associations between very short (OR = 1.14, 95% CI: 1.02-1.27), short (OR = 1.11, 95% CI: 1.04-1.19) and very long (OR = 1.09, 95% CI: 1.02-1.18) sleep durations and abdominal obesity after adjusting for potential confounding factors.
Conclusions: Our findings suggest that subjects with shorter or longer sleep durations have a much higher risk of abdominal obesity than those with optimal sleep durations. Shorter sleep durations may result in higher risk for abdominal obesity than longer sleep durations.
... We found an association between ISD and students who were physically inactive; this, in turn, promotes weight gain [41]. Similarly, Wang et al. [42] found that those with short sleep duration were less physically active than non-short sleep duration. Some studies found no significant relationship between PA and sleep duration or quality [43], while other studies found that short sleep duration engaged in decreased physical exercises in the next day [44], which can be explained as insufficient sleep is contributed to daytime tiredness which impacts on PA [41]. ...
Objectives
To assess the prevalence of overweight, obesity and Insufficient Sleep Duration (ISD) and to investigate their relationship with related lifestyle factors among school-aged students. Obesity in childhood and adolescence is a serious health concern as it may have long term risk for overweight and obesity in adulthood.
Methods
This is a cross-sectional study of 1,611 students aged between 10 and 18 years from Al Ain city, United Arab Emirates. Data were collected using a multistage stratified random sampling method using a validated questionnaire and the level of significance was set at p<0.05.
Results
The prevalence of overweight and obesity was 42.4%. ISD was 36.6% among students. Higher BMI was significantly related to being a male and inactive (95% CI=0.03–0.23), daily coffee consumption (95% CI=0.03–0.1), older age (95% CI=0.01–0.02), less average sleep duration (95% CI=−0.02 to −0.003) and spending more time on TV/videogames (95% CI=0.01–0.07). The likelihood of ISD was significantly lower among students who consumed breakfast daily (OR=0.58, 95% CI=0.41–0.83), spent less time on smart devices (OR=0.63, 95% CI=0.47–0.84), and never consumed energy drinks or soft drinks (OR=2.64, 95% CI=1.13–6.16, OR=2.02, 95% CI=1.24–3.29, respectively).
Conclusions
The prevalence of overweight and obesity among school-aged students is high. ISD and related lifestyle factors are significantly associated with overweight and obesity. Study findings emphasize the need to address and implement successful strategies for a healthy lifestyle starting from early childhood to combat the increasing rates of overweight and obesity in adulthood.
... Previous studies reported that sleep habits were better in middle school students than in high school students. Further, short sleep duration correlated with improved grades [31] and increasing competitive pressure during university entrance exams [32,33]. ...
Background
This cross-sectional study aimed to examine the relationship between sleep habits and oral disease symptoms in adolescents.
Methods
Among 62,276 adolescents who participated in the 13th Korea Youth Risk Behavior Web-based Survey (2017), we selected a total of 54,766 adolescents (age, 12–18 years; male, 49.9%) for the final analysis, after excluding those who did not report their sleep duration. The 13th Korea Youth Risk Behavior Web-based Survey data were obtained from a stratified, multistage, clustered sample. Independent variables included general characteristics, oral health behavior, sleep types, sleep duration, and sleep quality; dependent variables comprised oral disease symptoms. Sleep was categorized according to bedtime astype A (bedtime < 1 a.m.) and type B (bedtime ≥ 1 a.m.). Data were analyzed using logistic regression analysis. Statistical significance was set at p < 0.05.
Results
After adjusting for all covariates, adolescents with type A sleep had a higher risk of toothache on chewing (OR = 1.08, 95% CI 1.02–1.15) than adolescents with type B. Adolescents who slept for 6 h or less each night had a higher risk of pain in the tongue and buccal mucosa (OR = 1.35, 95% CI 1.18–1.54), gingival pain, and bleeding (OR = 1.31, 95% CI 1.19–1.45) than those who slept for more than 8 h. Adolescents with low quality of sleep had a higher risk of toothache or throbbing (OR = 1.70, 95% CI 1.60–1.81), toothache on chewing (OR = 1.73, 95% CI 1.65–1.82), and halitosis (OR = 1.51, 95% CI 1.41–1.59) than those with high quality of sleep.
Conclusions
Our findings indicate that some oral symptoms are related to sleep duration and quality. It is essential to inculcate good sleeping habits in adolescents by emphasizing the effects of inadequate sleep duration and quality.
