Young adults (YA) are at high risk for insufficient sleep and obesity. However, little research has focused on the association between sleep and obesity in this population. The present study examined the association between reported time in bed (TIB) and body mass index (BMI) in YAs. Participants were 250 18-25 year-olds who completed an online survey assessing several factors associated with weight control. After controlling for significant covariates, TIB was significantly associated with BMI. Specifically, "less than 6 hours/night" TIB was associated with increased BMI compared to the referent category (7 to <8 hours/night) (p = .01). Findings demonstrate that young adults who report shorter TIB are more likely to be classified as having higher BMI.
年轻人（YA）睡眠不足和肥胖的风险很高。然而，很少有研究关注这个人群中睡眠与肥胖之间的关系。本研究探讨了报告的卧床时间（TIB）与年轻人身体质量指数（BMI）之间的关系。参与者为 250 名 18-25 岁的年轻人，他们完成了一项在线调查，评估了与体重控制相关的几个因素。在控制了重要的协变量后，TIB 与 BMI 显著相关。具体来说，与参照类别（7 至<8 小时/夜）相比，“少于 6 小时/夜”的 TIB 与 BMI 增加相关（p =.01）。研究结果表明，报告 TIB 较短的年轻人更有可能被归类为 BMI 较高。
