In the last decade, the technological advances have led to increased usage of the Internet. Internet-based games are now more readily available, and they are also more attractive and engageable for individuals. Previous studies have established university students as vulnerable population with regards to IGD. Despite the unique stressors and demands of the course, there is little information about the pooled prevalence of IGD in medical students.
The current meta-analysis aims to establish the pooled prevalence of IGD among medical students in different countries, and factors affecting the pooled prevalence.
A comprehensive search was conducted from 23 May 2021 to 30 May 2021. The following databases were searched: PubMed, PsychINFO, Cochrane CENTRAL, Google Scholar, Scopus, Web of Science, Embase, Science Direct. The search terminologies included permutations of the keywords for IGD and medical students. All statistical analysis was performed with the Comprehensive Meta-analysis Version 3.0 program based on random-effects model.
Three hundred ninety-six articles were identified from the search of the databases. The final data set consisted of 6 studies with a pooled cohort size of 2,236 medical students. The pooled prevalence of IGD in each country is as follows: Egypt had the highest prevalence rate of 10.9% (95% CI: 7.3-16.1%), followed by Saudi Arabia (8.8, 95% CI: 5.7-13.2%), Indonesia (6.1, 95% CI: 0.7-37.5%) and India (3.8, 95% CI: 2.7-5.5%) ( < 0.005).
In conclusion, this meta-analysis reports that the pooled prevalence of IGD among medical students from different countries is 6.2%, which is around twice as high than that of the general population.
在过去十年中，技术进步导致互联网使用增加。基于互联网的游戏现在更容易获得，而且它们对个人也更具吸引力和参与性。先前的研究已将大学生确定为与互联网游戏障碍（IGD）相关的易感人群。尽管医学课程有其独特的压力源和要求，但关于医学生中IGD的合并患病率的信息却很少。
当前的荟萃分析旨在确定不同国家医学生中IGD的合并患病率以及影响合并患病率的因素。
于2021年5月23日至2021年5月30日进行了全面检索。检索了以下数据库：PubMed、PsychINFO、Cochrane CENTRAL、谷歌学术、Scopus、科学网、Embase、Science Direct。检索术语包括IGD和医学生的关键词排列组合。所有统计分析均使用基于随机效应模型的综合荟萃分析3.0版程序进行。
从数据库检索中识别出396篇文章。最终数据集包括6项研究，合并队列规模为2236名医学生。每个国家IGD的合并患病率如下：埃及患病率最高，为10.9%（95%置信区间：7.3 - 16.1%），其次是沙特阿拉伯（8.8，95%置信区间：5.7 - 13.2%）、印度尼西亚（6.1，95%置信区间：0.7 - 37.5%）和印度（3.8，95%置信区间：2.7 - 5.5%）（P < 0.005）。
总之，这项荟萃分析报告称，不同国家医学生中IGD的合并患病率为6.2%，约为普通人群的两倍。
