Obesity is currently an epidemic in Korea, and sleep duration is thought to be one of the risk factors for obesity. The objective of this study was to test the hypothesis that short sleep duration is associated with obesity in Korean adults.
The data from the 2001 Korean National Health and Nutrition Survey were used, and 6,174 subjects aged 18 approximately 80 years were included in the analysis. Sleep duration was measured using information obtained from self-reported questionnaires. Obesity, the main outcome variable, was measured according to body mass index. Multiple regression modeling was used to adjust for potential confounding variables.
The study results revealed a negative association between sleep duration and body mass index among Korean adults. These associations persisted after controlling for the potential confounding variables.
These findings support the hypothesis that sleep duration is associated with obesity in Korean adults. In addition, these observations support earlier experimental sleep studies and provide a basis for future studies on weight control intervention by increasing the amount of sleep.
肥胖目前在韩国呈流行态势，睡眠时间被认为是肥胖的风险因素之一。本研究的目的是检验以下假设：睡眠时间短与韩国成年人肥胖有关。
使用2001年韩国国民健康与营养调查的数据，分析纳入了6174名年龄在18至80岁之间的受试者。睡眠时间通过自我报告问卷获得的信息进行测量。肥胖作为主要结局变量，根据体重指数进行测量。采用多元回归模型对潜在的混杂变量进行校正。
研究结果显示，韩国成年人的睡眠时间与体重指数之间存在负相关。在控制了潜在的混杂变量后，这些关联依然存在。
这些发现支持了睡眠时间与韩国成年人肥胖有关这一假设。此外，这些观察结果支持了早期的睡眠实验研究，并为未来通过增加睡眠时间进行体重控制干预的研究提供了依据。
