Students starting at university tend to adopt unhealthy behaviors. With students expected to sit during classes, their academic schedule may be responsible for their activity patterns. The aim of the current study was to investigate the relationship between university students' academic schedule and day-to-day variations in sedentary behavior (SB) and physical activity (PA). The activity of 317 first-year undergraduate students (mean age 19.6 ± 1.4 years, 69.4% female, 30.0% male, and 0.6% other) was measured with the activPAL3™ triaxial monitor for seven consecutive days. Each class hour was found to be associated with 9.0 additional minutes of SB (95% CI [4.9, 13.1]), 54 additional seconds of moderate-to-vigorous PA (MVPA; 95% CI [12, 96]), and 12.2 min less time in bed (95% CI [-16.6, -7.8]). Active SB ratio (total duration of SB bouts < 30 min divided by total SB duration) decreased by 0.011 per hour of class scheduled for the students (95% CI [-0.016, -0.006]). Light PA (LPA) was not significantly associated with class duration. Students tend to cycle more on days with classes. Seated transportation was not significantly related to whether the students had classes or not. Overall, the academic schedule is associated with SB and PA in students.
大学生入学时往往会养成不健康的行为习惯。由于学生在上课时需要坐着，他们的学术日程可能是导致其活动模式的原因。本研究旨在调查大学生的学术日程与日常久坐行为（SB）和身体活动（PA）之间的关系。通过使用 activPAL3™三轴监测器，对 317 名一年级本科生（平均年龄 19.6±1.4 岁，69.4%为女性，30.0%为男性，0.6%为其他性别）进行了为期 7 天的连续监测。结果发现，每节课与 9.0 分钟的额外 SB（95%CI [4.9, 13.1]）、54 秒的中等到剧烈 PA（MVPA；95%CI [12, 96]）和 12.2 分钟的床上时间减少（95%CI [-16.6, -7.8]）相关。每小时的课程安排使学生的 SB 比（总 SB 时间中小于 30 分钟的 SB 持续时间除以总 SB 时间）减少了 0.011（95%CI [-0.016, -0.006]）。LPA 与课程持续时间无显著相关性。学生在有课的日子里往往更倾向于进行循环运动。上课与否与坐着的交通方式没有明显的关系。总的来说，学术日程与学生的 SB 和 PA 有关。
