To characterize the context, patterns, and correlates of sedentary behavior (SB) in university students. A total of 95 adults (41% men) enrolled in 34 different undergraduate majors. SB was assessed by questionnaire and accelerometer. Objective SB and moderate-to-vigorous physical activity (MVPA) accounted for 8.4 ± 1.5 and 1.2 ± 0.5 h·day, respectively. Most SB was spent in occupational, leisure, and screen time behaviors, and was accumulated in short bouts of 10 min or longer. Women were more sedentary than men (522.0 ± 80.3 vs. 486.1 ± 91.3 min·day, = 0.03) and engaged in more prolonged bouts of SB. Correlates of SB included female sex, smoking, light activity, MVPA, and markers of obesity, with higher levels of light activity and current smoking the strongest and most consistent correlates of reduced SB. University students engage in high amounts of SB and accumulate most of their SB in short bouts, with differences in patterns of SB between men and women.
为了描述大学生久坐行为（SB）的背景、模式和相关性。共有 95 名成年人（41%为男性）参与了 34 个不同的本科专业。通过问卷和加速度计评估 SB。客观 SB 和中等到剧烈的体力活动（MVPA）分别占 8.4±1.5 和 1.2±0.5 h·day。大多数 SB 发生在职业、休闲和屏幕时间行为中，并且以 10 分钟或更长时间的短时间爆发积累。女性比男性久坐（522.0±80.3 与 486.1±91.3 min·day， = 0.03），并且从事更长时间的 SB。SB 的相关因素包括女性、吸烟、轻度活动、MVPA 和肥胖标志物，其中轻度活动水平和当前吸烟与减少 SB 的相关性最强且最一致。大学生久坐时间长，且大部分 SB 以短时间爆发的形式积累，男女之间 SB 模式存在差异。
