Abstract

Background: Sedentary behavior is associated with various adverse health outcomes. Medical students often experience high academic demands, leading to increased sedentary time. This study aimed to evaluate the effectiveness of a mobile app providing real-time feedback in reducing total sedentary time and prolonged sedentary bouts and in promoting physical activity among medical students. Methods: Seventy-seven medical students from Jazan University (mean age: 21.4 years; range: 20-25 years) participated in this study. Participants were assigned to either the control group (n = 40) or the intervention group (n = 37). The intervention group received real-time vibration feedback via a mobile app, prompting movement every 30 min of sedentary time, while the control group received no intervention. Sedentary behavior and physical activity levels were assessed using the Activities Completed Over Time in 24 h. Paired t-tests were conducted to examine within-group changes, and a two-way ANOVA was used to assess the interaction effect of time and group on sedentary time and physical activity. Results: After six weeks, the intervention group showed significant within-group reductions in their total sedentary time of 1.82 h (p = 0.01) and prolonged sedentary bouts of 1.91 h (p = 0.001), while the control group had no significant changes. Physical activity levels did not significantly change within either group. The two-way ANOVA revealed that there was no significant change over time between the two groups in their total sedentary time F (1, 75) = 1.590, p = 0.21, prolonged sedentary bouts F (1, 75) = 3.499, p = 0.06, or physical activity F (1, 75) = 0.565, p = 0.45. Conclusions: Real-time feedback from mobile apps resulted in significant within-group reductions in total and prolonged sedentary time among medical students in the intervention group. Low-cost mobile apps providing real-time feedback may be an effective intervention for reducing sedentary behavior among medical students, potentially improving their health and well-being.

智能手机应用的实时振动反馈可减少医学生的久坐时间，但不会增加他们的体育锻炼。

背景：久坐不动的行为与各种不良健康后果有关。医科学生往往面临很高的学业要求，导致久坐时间增加。本研究旨在评估一款提供实时反馈的手机应用在减少总久坐时间、延长久坐时间以及促进医学生体育锻炼方面的效果。研究方法来自贾赞大学的 77 名医学生（平均年龄：21.4 岁；年龄范围：20-25 岁）参与了这项研究。参与者被分配到对照组（40 人）或干预组（37 人）。干预组通过手机应用获得实时振动反馈，每久坐 30 分钟就会提示运动，而对照组则不接受任何干预。采用配对 t 检验来检验组内变化，并采用双向方差分析来评估时间和组别对久坐时间和体力活动的交互影响。结果：六周后，干预组的总久坐时间显著减少了 1.82 小时（p = 0.01），长时间久坐时间显著减少了 1.91 小时（p = 0.001），而对照组没有显著变化。两组的体力活动水平均无明显变化。双向方差分析显示，两组的总久坐时间 F (1, 75) = 1.590，p = 0.21，长时间久坐 F (1, 75) = 3.499，p = 0.06，体力活动 F (1, 75) = 0.565，p = 0.45，均无明显变化。结论手机应用的实时反馈使干预组医学生的总久坐时间和长时间久坐时间在组内显著减少。提供实时反馈的低成本手机应用可能是减少医学生久坐行为的有效干预措施，有可能改善他们的健康和福祉。
