Physical activity level decreases during young adulthood. As social media are nowadays widely used and are included into many people's daily routines, the interventions on these websites have the possibilities to be integrated into those routines without becoming a burden. The aim of this study was to assess physical activity level among first- and fifth-year medical students and social media intervention with the aim to improve physical activity among them.
Prospective longitudinal study was conducted during October of 2016 at the Faculty of Medicine, University of Belgrade, Serbia. The study included 375 first- and fifth-year students.
At the baseline, students filled in the questionnaire and were asked to join a Facebook discussion group. The intervention consisted of motivation for physical activity through motivational pictures, texts, and discussions. The second assessment was carried out after one month. Based on the reported physical activity level, students were divided into groups: sufficient (>600 metabolic equivalent [MET]-minutes/week) and insufficient physical activity (≤600 MET-minutes/week).
Total of 85.4% of students were sufficiently active at the baseline, whereas 90.4% were sufficiently active after one month. Multivariate logistic regression analysis showed that students who were part of the Facebook group (odds ratio [OR]: 3.51, 95% confidence interval [CI]: 1.46-8.43) and students who had sufficient physical activity at the baseline (OR: 5.44, 95% CI: 2.44-12.13) had a higher likelihood to be sufficiently active after one month.
Social media are shown to be valuable in health-promoting interventions and can be used for interventions targeting lifestyle change among young adults.
年轻人的身体活动水平会随着年龄的增长而下降。由于社交媒体现在被广泛使用，并已纳入许多人的日常生活，因此这些网站上的干预措施有可能融入到日常生活中，而不会成为负担。本研究旨在评估医学生一年级和五年级学生的身体活动水平，并对其进行社交媒体干预以提高他们的身体活动水平。
这是一项 2016 年 10 月在塞尔维亚贝尔格莱德大学医学院进行的前瞻性纵向研究。研究纳入了 375 名一年级和五年级学生。
在基线时，学生填写问卷并被要求加入 Facebook 讨论组。干预措施包括通过激励图片、文字和讨论来激励身体活动。一个月后进行第二次评估。根据报告的身体活动水平，学生被分为两组：足够（>600 代谢当量 [MET]-分钟/周）和不足（≤600 MET-分钟/周）。
基线时，85.4%的学生身体活动充足，一个月后，90.4%的学生身体活动充足。多变量逻辑回归分析显示，参加 Facebook 小组的学生（比值比 [OR]：3.51，95%置信区间 [CI]：1.46-8.43）和基线时身体活动充足的学生（OR：5.44，95% CI：2.44-12.13）在一个月后更有可能保持充足的身体活动。
社交媒体在促进健康的干预措施中具有重要价值，可用于针对年轻人生活方式改变的干预措施。
