Abstract
Objectives
This study aimed to (i) compare children's lifestyle by urbanization level and (ii) examine the association between children's body mass index (BMI) and the risk of having unhealthy sleep (American Academy of Pediatrics).
Methods
Eight thousand one hundred fifty-nine children (4124 females) aged 6–9 years were observed and classified as urban or nonurban. Height and weight were measured, and the BMI was calculated. Sleep habits, sedentary behaviors (i.e., TV viewing, computer and electronic games use), and active play were assessed by questionnaire. One-way analysis of covariances (ANCOVAs) and logistic regression analysis were used, with adjustments to potential confounders.
Results
Urban males were significantly less active and spent more time in all sedentary activities than their nonurban peers during the week and the weekend. Urban girls spent significantly more time than their nonurban counterparts watching TV and playing electronic games. Furthermore, both urban and nonurban children with higher BMI had a relative higher risk of having unhealthy sleep duration.
Conclusions
Findings revealed important associations between BMI and sleep duration in both urban and nonurban children. Place of residence has an important impact on weight status of this sample of children.
期刊介绍：
The American Journal of Human Biology is the Official Journal of the Human Biology Association.
The American Journal of Human Biology is a bimonthly, peer-reviewed, internationally circulated journal that publishes reports of original research, theoretical articles and timely reviews, and brief communications in the interdisciplinary field of human biology. As the official journal of the Human Biology Association, the Journal also publishes abstracts of research presented at its annual scientific meeting and book reviews relevant to the field.
The Journal seeks scholarly manuscripts that address all aspects of human biology, health, and disease, particularly those that stress comparative, developmental, ecological, or evolutionary perspectives. The transdisciplinary areas covered in the Journal include, but are not limited to, epidemiology, genetic variation, population biology and demography, physiology, anatomy, nutrition, growth and aging, physical performance, physical activity and fitness, ecology, and evolution, along with their interactions. The Journal publishes basic, applied, and methodologically oriented research from all areas, including measurement, analytical techniques and strategies, and computer applications in human biology.
Like many other biologically oriented disciplines, the field of human biology has undergone considerable growth and diversification in recent years, and the expansion of the aims and scope of the Journal is a reflection of this growth and membership diversification.
The Journal is committed to prompt review, and priority publication is given to manuscripts with novel or timely findings, and to manuscripts of unusual interest.
