Sedentary behavior (SB) is highly prevalent among university students and has increased during COVID-19 pandemic. As SB is associated with negative health outcomes, appropriate prevention measures in the university setting are needed.
This pilot study aimed at investigating the effects of videos using different message strategies to interrupt SB in the collective of university students during online lectures.
During online lectures, university students ( = 96) were shown one of three videos on the interruption of SB. The videos differed in their message strategies with regard to evidence type (statistical vs. narrative) and vividness (static vs. animated images). Demographics, health variables (SB intentions, SB attitudes) and selected media reception variables (identification, homophily, counterarguing) were examined as possible influence factors on the interruption of SB evoked by watching the video.
Approximately half of the students interrupted sedentary behavior during watching the videos and students of the older age group (cut-off: median = 22 years) interrupted SB significantly more often ( = 0.046). The interruption of SB was predicted by SB intentions ( < 0.05). Identification with characters significantly predicted the intentions to reduce SB ( < 0.001), with a large effect of the overall regression model ( = 0.47).
Considering the increased digitalization in general and restrictions due to COVID-19 pandemic, videos seem to be a useful tool to interrupt SB among university students during online lectures. Narrative formats could facilitate the intention to reduce SB, which in turn could have a positive impact on the interruption of SB. However, further research on effective communication and message strategies is needed.
久坐行为（SB）在大学生中非常普遍，并且在 COVID-19 大流行期间有所增加。由于 SB 与负面健康结果有关，因此需要在大学环境中采取适当的预防措施。
本初步研究旨在调查在在线讲座期间使用不同信息策略的视频对打断大学生群体中 SB 的效果。
在在线讲座期间，向 96 名大学生展示了三种关于打断 SB 的视频之一。这些视频在信息策略方面有所不同，涉及证据类型（统计与叙述）和生动性（静态与动画图像）。将人口统计学、健康变量（SB 意图、SB 态度）和选定的媒体接受变量（认同、亲和力、反驳）作为观看视频可能影响打断 SB 的因素进行了检查。
大约一半的学生在观看视频时打断了久坐行为，年龄较大的学生（截止年龄中位数=22 岁）打断 SB 的频率显著更高（ = 0.046）。SB 意图（ < 0.05）预测了 SB 的中断。与角色的认同显著预测了减少 SB 的意图（ < 0.001），整个回归模型的效应量较大（ = 0.47）。
考虑到总体上数字化的增加和由于 COVID-19 大流行而造成的限制，视频似乎是在在线讲座期间打断大学生 SB 的有用工具。叙述格式可以促进减少 SB 的意图，从而对打断 SB 产生积极影响。但是，需要进一步研究有效的沟通和信息策略。
