During recent years, a large number of studies on the effects of electromagnetic fields emitted by cellular mobile phones on human cognitive performance have been carried out. However, the results have been ambiguous. We carried out the current meta-analysis in order to investigate the impact of electromagnetic fields emitted by mobile phones on human cognition. Seventeen studies were included in the meta-analysis as they fulfill several requirements such as single- or double-blind experimental study design, and documentation of means and standard deviations of dependent variables. The meta-analysis was carried out as a group comparison between exposed and non-exposed subjects. No significant effects of electromagnetic fields emitted by Global System for Mobile Communications (GSM) and Universal Mobile Telecommunications System (UMTS) mobile phones were found. Cognitive abilities seem to be neither impaired nor facilitated. Results of the meta-analysis suggest that a substantial short-term impact of high frequency electromagnetic fields emitted by mobile phones on cognitive performance can essentially be ruled out.
近年来，人们开展了大量关于移动手机发射的电磁场对人类认知能力影响的研究。然而，研究结果并不明确。我们进行了此次荟萃分析，以探究手机发射的电磁场对人类认知的影响。17项研究被纳入荟萃分析，因为它们满足了诸如单盲或双盲实验研究设计以及记录因变量的均值和标准差等多项要求。荟萃分析是在暴露组和非暴露组受试者之间进行的组间比较。未发现全球移动通信系统（GSM）和通用移动通信系统（UMTS）手机发射的电磁场有显著影响。认知能力似乎既未受损也未得到促进。荟萃分析结果表明，基本上可以排除手机发射的高频电磁场对认知能力产生实质性短期影响的可能性。
