“…Our study found that weekend sleep duration, but not weekday sleep duration, was associated with childhood abdominal obesity. In support of our results, a recent epidemiological study in 1728 children in Greece found that the association between sleep duration and overweight/obesity was stronger on weekends than on weekdays ( 11 ).

“…Apart from sleep duration, sleep timing, including wake-up time and bedtime, may also be an important contributor to childhood obesity (11,(37)(38)(39)(40). In a recent observational cross-sectional study on 2200 Australian children aged 9-16 years, it was shown that independent of sleep duration, later bedtime/wake-up time was associated with 1.47 times higher risk of obesity compared with the early bedtime/wake-up time pattern (41).…”

“…Short sleep duration is very common in modern society, with approximately onethird to two-thirds of adolescents complain about insufficient sleep (8)(9)(10). Although emerging evidences from both crosssectional and longitudinal studies have indicated the close relationship between short sleep duration and obesity (11)(12)(13), including in Chinese children (14)(15)(16)(17), studies focusing on the relationship between sleep duration and abdominal obesity are still limited. Recently, several studies found that sleeping longer on weekends may help ameliorate some of the effects of insufficient sleep during the weekdays, which suggested that weekday-weekend variability in sleep duration may play a role in overweight and obesity (18,19).…”

“…In recent years, sleep timing, including wake-up time and bedtime, is another important modifiable behavior, which is closely related to childhood obesity. Although there were many studies regarding the associations between wake-up time, bedtime, and childhood obesity, the results were inconsistent ( 11 , 23 , 24 ). Additionally, few studies on the associations of wake-up time, bedtime with abdominal obesity among Chinese children were available.…”

ObjectiveTo investigate the associations of sleep duration, wake-up time, bedtime, and childhood abdominal obesity, and to test whether there is a weekday/weekend difference and the potential modifying role of sex.MethodsThis cross-sectional study was based on the Students’ Constitution and Health Survey and included 9559 students (4840 boys and 4719 girls) aged 7–18 years (7227 aged 7–12 years, 2332 aged 13–18 years). They were divided into two groups (control group and group with abdominal obesity). The physical measurements included children and youth body height, body weight, and waist circumference (WC). A parent-report questionnaire was used to collect the information about parent characteristics as well as lifestyle and sleep patterns (sleep duration, bedtime, and wake-up time of weekdays and weekends) of children and youth.ResultsThe prevalence of abdominal obesity was 30.57% and the percentages of sleep duration <9 hours/day, wake-up time before 07:00 am on weekdays and weekends, bedtime after 10:00 pm on weekends were significantly higher in the group with abdominal obesity. After adjusting for confounders, sleep duration <9 hours/day on weekends was inversely related to abdominal obesity in the overall subjects, regardless of their sex and age, while bedtime after 10:00 pm on weekends was inversely related to abdominal obesity only in the overall subjects, boys, and children aged 7–12 years. Logistic regression models in all subjects showed that shorter hours of weekends sleep duration were associated with greater risks of abdominal obesity, even after adjusting for all confounders, including wake-up time and bedtime. The adjusted odds ratios and 95% confidence intervals of abdominal obesity (with ≥10 hours/day as the reference group) for children with 9–10 hours/day, 8–9 hours/day, and <8 hours/day of weekend sleep duration were 1.23 (1.04–1.46), 1.59 (1.32–1.91) and 1.83 (1.42–2.36), respectively. Specifically, after stratification by sex and age, this phenomenon was only observed in boys and children aged 7–12 years.ConclusionsSleep duration and bedtime on weekends were independently associated with the risk of childhood abdominal obesity, particularly in boys and children aged 7–12 years.

“…Pediatric obesity is closely linked to sleep problems [4], and increases the risk for SDB (20.8%) compared with children with normal-weight (6.3%) [5]. Furthermore, children with overweight/obesity often show suboptimal sleeping times, insufficient sleep efficiency, and short sleep duration [6][7][8][9][10]. The study of the associations between sleep disorders and behavioral and emotional functioning are particularly relevant in the context of childhood obesity.…”

Childhood obesity is one of the biggest public health challenges globally. It is associated with various adverse health consequences throughout life. Prevention and early intervention represent the most reasonable and costeffective approaches. Considerable progress has been achieved in the management of obesity in children and adolescents; yet, implementation in the real world remains a challenge. This article aimed to present an overview of the diagnosis and management of obesity in children and adolescents.
