Abstract
Purpose: Several studies showed that shortened sleep duration and subsequent sleep debt are related to obesity risk in children. We evaluated the association between habitual sleep restriction and eating behavior in school-aged children with and without obesity.
Patients and methods: In 131 school-aged children (mean [±SD] age 10.2 ± 2.0 years), we assessed eating behavior through the Child Eating Behavior Questionnaire (CEBQ). Actigraphic recordings measured sleep patterns for 4 consecutive days, including a weekend day. CEBQ scores were calculated in sleep-restricted children (having a nighttime sleep duration <8 hours) during week and weekend days and compared for those with (n = 67) and without obesity (n = 64). CEBQ scores were also compared between children with and without sleep compensation (a weekend catch-up in sleep duration ≥1 hour compared to weekdays' sleep duration).
Results: The mean sleep duration was 8.0 ± 1.3 h, and about 70% of children slept less than the daily sleep recommendation. Children having sleep restriction had higher scores in the four CEBQ pro-ingestion dimensions (all P<0.021) as well as lower "satiety responsiveness" but higher "emotional undereating" scores (both P<0.049). No differences in CEBQ were found in the normal-weight group when comparing children with or without sleep restriction. In the group with obesity, however, those sleep-restricted showed lower ratings in "slowness of eating" (P<0.015), "satiety responsiveness", and "food fussiness" (both P<0.035) compared to non-restricted, particularly during weekend days. Finally, children showing no sleep compensation on weekend days had higher pro-ingestion (all P<0.020) and lower anti-ingestion scores (all P<0.041).
Conclusion: Sleep duration was lower than the recommended sleep in this sample of school-aged children. Sleep restriction was associated with enhanced pro-ingestion eating behavior scores and reduced anti-ingestion scores. Sleep compensation appears to have a positive effect on eating behavior scores.
期刊介绍:
Nature and Science of Sleep is an international, peer-reviewed, open access journal covering all aspects of sleep science and sleep medicine, including the neurophysiology and functions of sleep, the genetics of sleep, sleep and society, biological rhythms, dreaming, sleep disorders and therapy, and strategies to optimize healthy sleep.
Specific topics covered in the journal include:
The functions of sleep in humans and other animals
Physiological and neurophysiological changes with sleep
The genetics of sleep and sleep differences
The neurotransmitters, receptors and pathways involved in controlling both sleep and wakefulness
Behavioral and pharmacological interventions aimed at improving sleep, and improving wakefulness
Sleep changes with development and with age
Sleep and reproduction (e.g., changes across the menstrual cycle, with pregnancy and menopause)
The science and nature of dreams
Sleep disorders
Impact of sleep and sleep disorders on health, daytime function and quality of life
Sleep problems secondary to clinical disorders
Interaction of society with sleep (e.g., consequences of shift work, occupational health, public health)
The microbiome and sleep
Chronotherapy
Impact of circadian rhythms on sleep, physiology, cognition and health
Mechanisms controlling circadian rhythms, centrally and peripherally
Impact of circadian rhythm disruptions (including night shift work, jet lag and social jet lag) on sleep, physiology, cognition and health
Behavioral and pharmacological interventions aimed at reducing adverse effects of circadian-related sleep disruption
Assessment of technologies and biomarkers for measuring sleep and/or circadian rhythms
Epigenetic markers of sleep or circadian disruption.
