This systematic review and meta-analysis aims to estimate the overall prevalence of Internet addiction among Iranian university students. A total of 49 articles written in Persian or English, without time limitation, were gathered. Databases of Scientific Information Database, MagIran, PubMed, Scopus, and Web of Science were searched during the period from February 13 to March 13, 2018. The following keywords and their possible combinations were used: Iran, student, Internet dependency, Internet addiction, and problematic Internet use. The Cochran's Q test was used to test the heterogeneity among the studies, and because heterogeneity was not significant, the random effects model was used to estimate the overall prevalence of Internet addiction. Data analysis was performed using STATA, version 12. Meta-analysis of 49 selected articles with a total sample size of 16,585 indicated that the overall prevalence of Internet addiction among Iranian students was 31.51 percent (95% confidence interval: 26.47–36.55). In addition, meta-regression analysis showed no significant relationship between Internet addiction and year of publication (p = 0.972) and sample size (p = 0.915). About one-third of Iranian students have Internet addiction. It is necessary to provide training workshops on learning about the consequences of Internet addiction and its management.

伊朗大学生网络成瘾的患病率：系统回顾和荟萃分析

这项系统回顾和荟萃分析旨在估计伊朗大学生网络成瘾的总体流行率。共收集了 49 篇用波斯语或英语撰写的文章，没有时间限制。在 2018 年 2 月 13 日至 3 月 13 日期间，检索了 Scientific Information Database、MagIran、PubMed、Scopus 和 Web of Science 的数据库。使用了以下关键词及其可能的组合：伊朗、学生、网络依赖、网络成瘾、和有问题的互联网使用。Cochran's Q 检验用于检验研究之间的异质性，并且由于异质性不显着，因此使用随机效应模型来估计网络成瘾的总体患病率。使用 STATA 第 12 版进行数据分析。对总样本量为 16,585 的 49 篇选定文章的荟萃分析表明，伊朗学生网络成瘾的总体流行率为 31.51%（95% 置信区间：26.47-36.55）。此外，元回归分析显示网络成瘾与出版年份之间没有显着关系（p  = 0.972）和样本量（p  = 0.915）。大约三分之一的伊朗学生有网络成瘾。有必要提供培训讲习班，以了解网络成瘾的后果及其管理。
