背景资料：我们调查了来自移动的手机和其他无线设备的射频电磁场（RF-EMF），或无线设备本身的非辐射相关因素，是否与瑞士中部青少年健康症状报告的增加有关。方法：在一项前瞻性队列研究中，439名研究参与者（参与率：36.8%），年龄为12 - 17岁，完成了关于基线（2012/2013）和一年后（2013/2014）时移动的和无绳电话使用、自我报告症状和可能混杂因素的问卷。操作员记录的移动的电话数据，获得了一个亚组的234名青少年。考虑到影响RF-EMF暴露的各种因素，计算了大脑和全身的RF-EMF剂量测量值。使用混合逻辑截面模型和队列方法分析数据，其中我们研究了一年内的累积剂量是否与基线和随访之间的新症状发作相关。所有的分析进行了调整，为相关的混杂因素。结果：在后续的参与率为97%（425人）。在横断面和队列分析中，各种症状往往主要与使用测量相关，这些测量仅与RF-EMF暴露轻微相关，例如每天发送的短信数量（例如，疲劳：横断面分析的OR：1.81; 95%CI：1.202.74，队列分析的OR：1.87; 95%CI：1.04 - 3.38）。结果一般不太强烈或不相关的移动的电话通话时间和RF-EMF剂量measures.Conclusions：较强的关联症状不健康和无线通信设备的使用比RF-EMF剂量措施进行了观察。这样的结果模式不支持RF-EMF暴露和青少年的健康症状之间的因果关系，而是表明，广泛的媒体使用的其他方面与症状有关。
Background: We investigated whether radiofrequency electromagnetic fields (RF-EMF) from mobile phones and other wireless devices or by the wireless device use itself due to non-radiation related factors in that context are associated with an increase in health symptom reports of adolescents in Central Switzerland.Methods: In a prospective cohort study, 439 study participants (participation rate: 36.8%) aged 12-17 years, completed questionnaires about their mobile and cordless phone use, their self-reported symptoms and possible confounding factors at baseline (2012/2013) and one year later (2013/2014). Operator recorded mobile phone data was obtained for a subgroup of 234 adolescents. RF-EMF dose measures considering various factors affecting RF-EMF exposure were computed for the brain and the whole body. Data were analysed using a mixed -logistic cross-sectional model and a cohort approach, where we investigated whether cumulative dose over one year was related to a new onset of a symptom between baseline and follow-up. All analyses were adjusted for relevant confounders.Results: Participation rate in the follow-up was 97% (425 participants). In both analyses, cross-sectional and cohort, various symptoms tended to be mostly associated with usage measures that are only marginally related to RF-EMF exposure such as the number of text messages sent per day (e.g. tiredness: OR:1.81; 95%C1:1.202.74 for cross-sectional analyses and OR:1.87; 95%CI:1.04-3.38 for cohort analyses). Outcomes were generally less strongly or not associated with mobile phone call duration and RF-EMF dose measures.Conclusions: Stronger associations between symptoms of ill health and wireless communication device use than for RF-EMF dose measures were observed. Such a result pattern does not support a causal association between RF-EMF exposure and health symptoms of adolescents but rather suggests that other aspects of extensive media use are related to symptoms.
