The purpose of the study was to investigate the associations of device-measured total sedentary time and screen-based sedentary time with anxiety in college students.
Three hundred and twenty-one college students (mean age = 19.72 ± 1.18, 55.8% females) were recruited from Shanghai, China. Total sedentary time was objectively measured using accelerometry, while screen-based sedentary time was self-reported. Anxiety symptom was evaluated using the Self-Rating Anxiety Scale. Linear regression modeling was used to assess the associations of total sedentary time and screen-based sedentary time with anxiety symptom.
Accelerometer-assessed total sedentary time was not associated with anxiety symptom. Prolonged sedentary time on TV and movie viewing (>2 h on weekdays) and social media using (>2 h on weekdays and weekend) were associated with a higher level of anxiety. However, time on video gaming and recreational reading was not associated with anxiety symptom.
The findings indicated that screen-based sedentary behaviors but not total sedentary time were associated with anxiety symptom among college students. The associations of screen-based sedentary behaviors with anxiety symptom varied by the types of screen time.
本研究旨在探讨设备测量的总久坐时间和基于屏幕的久坐时间与大学生焦虑之间的关联。
从中国上海招募了 321 名大学生（平均年龄=19.72±1.18，55.8%为女性）。总久坐时间通过加速度计进行客观测量，而基于屏幕的久坐时间则通过自我报告进行测量。使用自评焦虑量表评估焦虑症状。线性回归模型用于评估总久坐时间和基于屏幕的久坐时间与焦虑症状之间的关联。
加速度计评估的总久坐时间与焦虑症状无关。在工作日长时间观看电视和电影（>2 小时）和社交媒体使用（>2 小时，包括工作日和周末）与更高水平的焦虑相关。然而，玩视频游戏和阅读娱乐类书籍的时间与焦虑症状无关。
研究结果表明，在大学生中，基于屏幕的久坐行为而非总久坐时间与焦虑症状有关。基于屏幕的久坐行为与焦虑症状的关联因屏幕时间类型而异。
