无线通信设备发射的微波射频电磁场（RF-EMF）对青少年神经认知功能的潜在影响存在争议。在先前的分析中，我们发现青少年的图形记忆分数的变化与较高的累积RF-EMF脑剂量相关。我们的目标是使用新的研究人群、剂量估计和控制培养基使用本身混淆的方法来随访我们之前的结果。对每个参与者的RF-EMF脑剂量进行建模。多变量线性回归模型适用于1年内的语言和图形记忆评分变化，以及估计的累积脑剂量和RF-EMF相关和不相关的媒体使用（）。由于记忆的半球侧化，我们进行了电话耳偏好的偏侧化分析。为了控制媒体使用行为的混杂因素，还对不同媒体使用组进行了分层分析。我们发现，图形记忆评分降低与估计的累积RF-EMF脑剂量评分的四分位数间距（IQR）增加相关：（95% CI：，0.03; IQR：）在整个样本中，（95% CI：，; IQR：）右侧用户（），以及（95% CI：，; IQR：）记录的网络操作员数据用于RF-EMF剂量估计（）。与RF-EMF无关的媒体使用没有表现出显着的关联或一致的模式，除了数据流量持续时间和非文字记忆之间的一致（非显着）的正相关。我们对瑞士青少年队列的研究结果需要在其他人群中得到证实，但表明RF-EMF大脑剂量对认知功能的潜在不良影响，涉及在使用移动的手机期间主要暴露的大脑区域。https://doi.org/10.1289/EHP2427
The potential impact of microwave radiofrequency electromagnetic fields (RF-EMF) emitted by wireless communication devices on neurocognitive functions of adolescents is controversial. In a previous analysis, we found changes in figural memory scores associated with a higher cumulative RF-EMF brain dose in adolescents. We aimed to follow-up our previous results using a new study population, dose estimation, and approach to controlling for confounding from media usage itself. RF-EMF brain dose for each participant was modeled. Multivariable linear regression models were fitted on verbal and figural memory score changes over 1 y and on estimated cumulative brain dose and RF-EMF related and unrelated media usage (). Because of the hemispheric lateralization of memory, we conducted a laterality analysis for phone call ear preference. To control for the confounding of media use behaviors, a stratified analysis for different media usage groups was also conducted. We found decreased figural memory scores in association with an interquartile range (IQR) increase in estimated cumulative RF-EMF brain dose scores: (95% CI: , 0.03; IQR: ) in the whole sample, (95% CI: , ; IQR: ) in right-side users (), and (95% CI: , ; IQR: ) when recorded network operator data were used for RF-EMF dose estimation (). Media usage unrelated to RF-EMF did not show significant associations or consistent patterns, with the exception of consistent (nonsignificant) positive associations between data traffic duration and verbal memory. Our findings for a cohort of Swiss adolescents require confirmation in other populations but suggest a potential adverse effect of RF-EMF brain dose on cognitive functions that involve brain regions mostly exposed during mobile phone use. https://doi.org/10.1289/EHP2427
