Insufficient Sleep Duration and Overweight/Obesity among Adolescents in a Chinese Population

Abstract

Objectives: The objective of this study was to investigate the relationship between sleep duration and overweight/obesity among Chinese adolescents. Methods: A school-based cross-sectional study was conducted among Chinese adolescents in 2016. In total, 2795 school-aged Chinese children aged 12 to 13 years participated in this study. Participants were asked to complete self-administered surveys during a 45-min class period in their classroom. Details of the questionnaire about health-related behaviors included sleep habits, physical activity, screen time, cigarette use, and alcohol use. Height, weight, waist circumference and hip circumference were directly measured. Results: The mean sleep duration was 8.7 h/day. In total, 43.0% of the participants had a sleep duration of less than 9 h/day. Sleep duration was significantly inversely related to BMI, waist circumference, hip circumference and WHtR in multiple linear regression analyses in both genders. Logistic regression models showed that insufficient sleep (<9 h/day) was associated with high odds of overweight/obesity among both young boys and girls. Conclusions: Insufficient sleep duration was associated with overweight/obesity in Chinese adolescents, and short sleep duration was probably associated with central adiposity, especially among boys.

The Relationship between the Number of Daily Health-Related Behavioral Risk Factors and Sleep Health of the Elderly in China

“…Substantial concrete evidence indicated that there was a significant negative effect on the individual's sleep health when people engaged in health-related risk behavior(s) [19,20,32,33]. This study concluded that with an increase in health-related risk behaviors, the negative effects on sleep health could be further increased, at least for both the increased prevalence of sleep problems and the deterioration of sleep quality.…”

“…Previous studies from developed countries or regions have confirmed the link between specific behaviors and sleep health. Health-related behavioral risk factors, including tobacco use, alcohol drinking, unhealthy dietary behaviors, as well as insufficient time for leisure activities and physical inactivity, have been shown to be associated with sleep health [17,19,20,32,33]. The results of these studies provide the theoretical basis for developing interventions that specifically target a particular health-related risk behavior.…”

Associations Between Sleep Duration, Wake-Up Time, Bedtime, and Abdominal Obesity: Results From 9559 Chinese Children Aged 7–18 Years

“…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).…”

Self-reported eating speed is associated with overweight among Chinese schoolchildren: a cross-sectional survey

“…Measurements In the general health examination, the height and body weight of all participants were measured by trained research staff. Details of the examination have been described in a previous publication of our group [15]. Body mass index (BMI) was calculated using the ratio of weight/height 2 (kg/m 2 ).…”
