“…A series of studies have provided strong evidence of an association between sleep duration and obesity in children (12)(13)(14)(15)(16)23). Our study found that short weekend sleep duration (OR for less than 9 hours) was associated with childhood abdominal obesity, even after adjusting for all confounders, including sleep timing wake-up time and bedtime.…”

“…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).…”

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.

“…Childhood overweight or obesity may be associated with an increased risk of future chronic diseases such as cardiovascular diseases, diabetes and orthopedic problems [3,4]. At the same time, some risk factors for being overweight or obesity have been identi ed, including high energy intake and low energy expenditure [5], physical inactivity [6], and sleep disorder [7]. Recently, eating speed has been identi ed as a potential independent risk factor for obesity or overweight, and accumulating studies indicates that eating quickly may play an important role in development of overweight and obesity.…”

This study aimed to examine the association between eating speed and overweight in Chinese schoolchildren. MethodsIn all, 664 schoolchildren (10-12 y) from 3 primary schools participated in this study in China. Their height and body weight were measured. Information about eating speed and other lifestyle behaviors was collected using a self-administered questionnaire. Multivariable logistic regression model was used to estimate the odds ratio (OR) and 95% con dence interval (95% CI) for overweight. ResultsData from 629 students were analyzed. 26.2% of participants reported they were eating fast. The prevalence of overweight (including obesity) was 22.9%, and the mean of sleep duration was 9.69 (SD= 0.63) hours (Table 1). In the multiple linear regression analysis, eating speed was negatively associated with BMI (B=-0.70; P 0.05) and TG (B=-0.16; P 0.05). In addition, participants who ate fast were more likely to be overweight (OR=1.81, 95% CI= 1.19 to 2.75) after adjusting for potential confounding factors. ConclusionsThis study indicates that eating fast is associated with overweight among Chinese school-children.
