The inclusion of "Internet gaming disorder (IGD)" in the fifth edition of Diagnostic and statistical manual of mental disorders (DSM-5) creates a possible line of research. Despite the fact that adolescents are vulnerable to IGD, studies had reported wide array of prevalence estimates in this population. The aim of this paper is to review the published studies on prevalence of IGD among adolescents. Relevant studies prior to March 2017 were identified through databases. A total of 16 studies met the inclusion criteria. The pooled prevalence of IGD among adolescents was 4.6% (95% CI = 3.4%-6.0%). Male adolescents generally reported higher prevalence rate (6.8%, 95% CI = 4.3%-9.7%) than female adolescents (1.3%, 95% CI = 0.6%-2.2%). Subgroup analyses revealed that prevalence estimates were highest when studies were conducted in: (i) 1990s; (ii) use DSM criteria for pathological gambling; (iii) examine gaming disorder; (iv) Asia; and (v) small samples (<1,000). This study confirms the alarming prevalence of IGD among adolescents, especially among males. Given the methodological deficits in past decades (such as reliance on DSM criteria for "pathological gambling," inclusion of the word "Internet," and small sample sizes), it is critical for researchers to apply a common methodology for assess this disorder.
《精神疾病诊断与统计手册》（DSM - 5）第五版中纳入“互联网游戏障碍（IGD）”开创了一条可能的研究方向。尽管青少年易患IGD，但此前的研究报告显示该人群的患病率估计差异很大。本文旨在综述已发表的关于青少年IGD患病率的研究。通过数据库检索出了2017年3月之前的相关研究。共有16项研究符合纳入标准。青少年中IGD的合并患病率为4.6%（95%置信区间 = 3.4% - 6.0%）。一般来说，男性青少年报告的患病率（6.8%，95%置信区间 = 4.3% - 9.7%）高于女性青少年（1.3%，95%置信区间 = 0.6% - 2.2%）。亚组分析显示，在以下情况下进行的研究中患病率估计最高：（i）20世纪90年代；（ii）使用DSM病理性赌博标准；（iii）检查游戏障碍；（iv）亚洲；以及（v）小样本（<1000）。本研究证实了青少年中IGD的患病率令人担忧，尤其是在男性中。鉴于过去几十年的方法学缺陷（如依赖DSM“病理性赌博”标准、包含“互联网”一词以及样本量小），研究人员采用通用方法评估这种疾病至关重要。
