The primary goal of the study was to identify sources of electromagnetic field (EMF) which are attributed to negative health outcomes by a general population of electrohypersensitive (EHS) individuals. Secondary goal was to investigate the differences in indicated sources in subgroups distinguished based on gender, sex, place of living, place of work and the distance between place of living and the nearest mobile phone base station (MPBS). The cross-sectional study aiming to describe and analyze the population of EHS subjects was performed using a web-based questionnaire. The full survey consisted of 32 questions and concerned participants' baseline characteristics and details on sensitivity to electronic devices. Participants were regarded as EHS if they answered "yes" to the question "Do the electric/electronic/telecommunication devices negatively affect your well-being?" and indicated at least one device which in their opinion had such an impact. We identified 408 EHS subjects, out of which 288 (70.73%) were females and 120 (29.27%) were males. Phones, especially mobile devices, were attributed to negative health outcomes by the highest number of subjects (309, 75.74% and 267, 65.44% for phones and mobile phones, respectively). Additional subgroup analysis indicated that older participants and participants who live closer to MPBS more often complained of physical symptoms attributed to MPBS impact (p = .02 and p < .01, respectively). Phones, especially mobile devices, are the most important source of EMF influencing EHS subjects. People who self-reported living closer to MPBS and older individuals seem to be remarkably more concerned about MPBS health impact.

哪些电磁场源是电敏感个体最关心的问题？ – 问卷研究与文献综述


该研究的主要目标是确定电磁场 (EMF) 的来源，这些来源可归因于一般电过敏 (EHS) 人群的负面健康结果。第二个目标是调查根据性别、性别、居住地、工作地点以及居住地与最近的移动电话基站（MPBS）之间的距离区分的亚组中指示源的差异。这项旨在描述和分析 EHS 受试者群体的横断面研究是使用基于网络的调查问卷进行的。完整的调查包括 32 个问题以及相关参与者的基线特征和对电子设备敏感性的详细信息。如果参与者对“电气/电子/电信设备是否会对您的健康产生负面影响？”的问题回答“是”，则被视为 EHS。并指出至少有一种设备在他们看来具有这样的影响。我们确定了 408 名 EHS 受试者，其中 288 名（70.73%）为女性，120 名（29.27%）为男性。最多的受试者将手机（尤其是移动设备）归因于负面健康结果（电话和移动电话分别为 309 人（75.74%）和 267 人（65.44%）。其他亚组分析表明，年龄较大的参与者和住得离 MPBS 较近的参与者更常抱怨 MPBS 影响造成的身体症状（分别为 p = .02 和 p < .01）。电话，尤其是移动设备，是影响 EHS 主题的最重要的 EMF 来源。自称住得离 MPBS 较近的人和老年人似乎更关心 MPBS 的健康影响。
