Although both sedentary behavior and sleep duration are risk factors for obesity, little evidence is provided regarding their mutual associations in young adults, who are at extreme risk of spending more time sitting and having irregular sleeping hygiene. Thus, the main purpose of the present study was to explore the associations between different sedentary behaviors and sleep duration. In this cross-sectional study, we recruited 2100 university students from the city of Zagreb. To assess sedentary behaviors and sleep duration, we used validated questionnaires. The associations between sedentary behaviors and sleep duration were analyzed using logistic regression analyses and were adjusted for sex, body-mass index, self-rated health, socioeconomic status, smoking status, binge drinking, psychological distress and chronic disease/s. Participants being in the third (OR = 1.45; 95% CI 1.05 to 2.01) and fourth (OR = 1.82; 95% CI 1.26 to 2.61) quartile of the screen-time, in the third (OR = 1.49; 95% CI 1.05 to 2.13) and fourth (OR = 1.72; 95% CI 1.22 to 2.42) quartile of the leisure-time sedentary behavior and in the fourth (OR = 1.45; 95% CI 1.04 to 2.02) quartile of the total sedentary behavior were more likely to be 'short' sleepers (<7 h). Also, participants being in the third (OR = 1.63; 95% CI 1.16 to 2.30) and fourth (OR = 1.93; 95% CI 1.33 to 2.81) quartile of the screen-time and in the fourth (OR = 1.45; 95% CI 1.05 to 2.00) quartile of the total sedentary behavior were more likely to be 'long' sleepers (>9 h). Our study shows that sedentary behavior in screen-time and total sedentary behavior are associated with both 'short' and 'long' sleep duration.
尽管久坐行为和睡眠时间都是肥胖的风险因素，但关于年轻人久坐行为和睡眠时间之间相互关系的证据很少，年轻人久坐的时间极长，且睡眠卫生习惯也不规律。因此，本研究的主要目的是探讨不同久坐行为与睡眠时间之间的关系。在这项横断面研究中，我们招募了来自萨格勒布市的 2100 名大学生。为了评估久坐行为和睡眠时间，我们使用了经过验证的问卷。使用逻辑回归分析来分析久坐行为和睡眠时间之间的关联，并根据性别、体重指数、自我评估健康状况、社会经济地位、吸烟状况、狂饮、心理困扰和慢性疾病/状况进行了调整。处于屏幕时间第三（OR=1.45；95%CI 1.05 至 2.01）和第四（OR=1.82；95%CI 1.26 至 2.61）四分位数的参与者，处于屏幕时间第三（OR=1.49；95%CI 1.05 至 2.13）和第四（OR=1.72；95%CI 1.22 至 2.42）四分位数的参与者，以及处于第四（OR=1.45；95%CI 1.04 至 2.02）四分位数的总久坐行为的参与者，更有可能是“短”睡眠者（<7 小时）。此外，处于屏幕时间第三（OR=1.63；95%CI 1.16 至 2.30）和第四（OR=1.93；95%CI 1.33 至 2.81）四分位数的参与者，以及处于第四（OR=1.45；95%CI 1.05 至 2.00）四分位数的参与者，处于总久坐行为的参与者更有可能是“长”睡眠者（>9 小时）。我们的研究表明，屏幕时间和总久坐行为中的久坐行为与“短”和“长”睡眠时间都相关。
