本研究的目的是前瞻性地调查暴露于移动电话和其他无线通信设备发出的射频电磁场（RF-EMF）是否与青少年的行为问题或注意力集中能力有关。HERMES（青少年使用手机对健康的影响）研究样本由439名年龄在12-17岁的瑞士青少年组成。行为问题采用优势与困难问卷（SDQ）进行评估，注意力集中能力采用标准化计算机化认知测试FAIT进行测量。进行了横断面和纵向（1年随访）分析，以调查行为问题和集中能力与不同暴露措施之间的可能关联：自我报告和操作员记录的无线通信设备使用情况、累积的RF-EMF脑和全身剂量以及测量的个人RF-EMF暴露。在横断面分析中，行为问题与几项自我报告的无线设备使用措施有关，但与操作员记录的移动电话使用措施无关，集中能力与几项自我报告和操作员记录的暴露有关。纵向分析表明没有关联。纵向分析中缺乏一致的接触-反应模式，这表明行为问题和注意力集中能力不受使用无线通信设备或RF-EMF接触的影响。信息偏差和反向因果关系可能是观察到的横断面结果的解释。(C) 2016 Elsevier GmbH版权所有。
The aim of this study is to prospectively investigate whether exposure to radiofrequency electromagnetic fields (RF-EMF) emitted by mobile phones and other wireless communication devices is related to behavioural problems or concentration capacity in adolescents.The HERMES (Health Effects Related to Mobile phonE use in adolescentS) study sample consisted of 439 Swiss adolescents aged 12-17 years. Behavioural problems were assessed using the Strengths and Difficulties Questionnaire (SDQ), concentration capacity of the adolescents was measured by means of a standardized computerized cognitive test named FAIT. Cross-sectional and longitudinal (1 year of follow-up) analyses were performed to investigate possible associations between behavioural problems and concentration capacity and different exposure measures: self-reported and operator-recorded wireless communication device use, cumulative RF-EMF brain and whole body dose and measured personal RF-EMF exposure.In the cross-sectional analyses behavioural problems were associated with several self-reported wireless device use measures but not operator-recorded mobile phone use measures, concentration capacity was associated with several self-reported and operator-recorded exposures. The longitudinal analyses point towards absence of associations.The lack of consistent exposure-response patterns in the longitudinal analyses suggests that behavioural problems and concentration capacity are not affected by the use of wireless communication devices or RF-EMF exposure. Information bias and reverse causality are likely explanations for the observed cross-sectional findings. (C) 2016 Elsevier GmbH. All rights reserved.
