Bottom Line: Frequent use of digital media may be associated with the development of attention-deficit/hyperactivity disorder (ADHD) symptoms in adolescence but more research is needed to know if the association is causal.

Why The Research Is Interesting: Digital media, including texting, video chatting and social media sites, are accessible, constantly available on mobile devices and intensely stimulating. But whether frequent use of this modern digital media is associated with the occurrence of ADHD symptoms in adolescence is unknown.

Who and When: 2,587 Los Angeles County high school students without symptoms of ADHD at study entry who were surveyed five times from September 2014 to December 2016.

What (Study Measures and Outcomes): Self-reported use of 14 different digital media activities, such as checking social media sites and texting (exposures); self-rated frequency of 18 ADHD symptoms in the six months preceding the survey (outcomes).

How (Study Design): This was an observational study. Researchers were not intervening for purposes of the study and cannot control all the natural differences that could explain the study findings.

Authors: Adam M. Leventhal, Ph.D., University of Southern California Keck School of Medicine, Los Angeles, and coauthors

Results: Frequently using multiple forms of digital media was associated with a higher likelihood of ADHD symptoms occurring over a 24-month period during adolescence.

Study Limitations: A self-rating survey for ADHD symptoms is insufficient to determine an ADHD diagnosis; there also is the possibility of reverse causation (ADHD is associated with sensation seeking which could prompt digital media use to satisfy a need for stimulation); and undetected baseline ADHD symptoms cannot be ruled out.

Study Conclusions:

青少年频繁使用数字媒体与注意力缺陷/多动症(ADHD)的症状有关联吗?

概要: 根据《美国医学会杂志》(JAMA)发表的一项研究,频繁使用数字媒体可能与青春期注意力缺陷/多动症(ADHD)症状的发展有关,但需要更多的研究来了解这种关联是否是因果关系。

 

为何对该问题感兴趣:数字媒体,包括短信,视频聊天和社交媒体网站等,都可以通过移动设备随时访问,并且非常刺激。 但是目前还不知道经常使用这些现代数字媒体与青春期ADHD症状的发生是否有关。

 

研究参与者及时间: 2587名在研究开始时没有ADHD症状的洛杉矶县高中生, 其在2014年9月至2016年12月期间接受了五次研究调查。

 

研究内容(研究手段及结果):自我报告的14种不同数字媒体活动的使用情况,例如查看社交媒体网站和发短信等(暴露); 自我评定的调查前六个月内18种ADHD症状频率(结果)。

 

如何研究(研究设计)这是一项观察性研究。 研究人员不会为研究目而进行干预,也无法控制可以解释研究结果的所有自然差异。

研究结果:频繁使用多种形式的数字媒体与在青春期时期的24个月内出现ADHD症状的可能性升高有关联。

 

研究局限:针对ADHD症状的自我评估不足以确定ADHD诊断; 还存在反向因果关系的可能性(ADHD与寻求感觉刺激有关,而这可能促使更多的使用数字媒体来满足刺激需求); 并且不能排除未检测到的基线ADHD症状。

 

研究结论:

结论及意义 在接受2年随访的青春期青少年中, 频繁使用数字媒体与其后的ADHD症状表现出有统计意义的中等关联度。但还需要进一步的研究以确定该关联是否是因果关系。
