Obesity in adolescence can continue up to adulthood and lead to various complications. There has been a continuous increase in the obesity incidence among adolescents, which is an emerging social issue. Studies have reported that decreased sleep duration in adolescents can have negative effects on health, leading to obesity. Therefore, in the present study, we aimed to investigate the relationship between sleep duration and body mass index among South Korean middle and high school students aged 12-18 years.
The participants of the Sixth National Health and Nutrition Survey conducted during 2013-2015 were screened. We selected 1,177 adolescents aged between 12 and 18 years who were enrolled in middle and high school or on leave of absence and had available data for sleep duration and body mass index (BMI) in the survey. Analyses of variance and covariance were performed after adjusting for confounding variables, including age, gender, waist circumference, and drinking experience, that showed significant correlations in univariate logistic regression.
The analysis of covariance revealed that an increase in sleep duration led to a corresponding decrease in the mean BMI among all students and middle school students.
Significant negative correlations were confirmed between sleep duration and BMI in all students and middle school students.
青少年肥胖可能持续到成年并导致各种并发症。青少年肥胖发生率持续上升,这是一个新出现的社会问题。研究报告称,青少年睡眠时间减少会对健康产生负面影响,导致肥胖。因此,在本研究中,我们旨在调查12至18岁韩国初高中学生的睡眠时间与体重指数之间的关系。
对2013 - 2015年期间进行的第六次全国健康与营养调查的参与者进行筛选。我们选择了1177名年龄在12至18岁之间的青少年,他们就读于初高中或正在休假,且在调查中有睡眠时间和体重指数(BMI)的可用数据。在对包括年龄、性别、腰围和饮酒经历等混杂变量进行调整后进行方差分析和协方差分析,这些变量在单因素逻辑回归中显示出显著相关性。
协方差分析显示,睡眠时间增加导致所有学生和中学生的平均BMI相应降低。
在所有学生和中学生中,睡眠时间与BMI之间均证实存在显著的负相关。
