The aim of this Swedish study was to investigate symptoms and risk indicators associated with reported hypersensitivity to electricity.
40 out of 241 employees of a telecommunications corporation reported hypersensitivity to electricity in a self-administered questionnaire and were defined as cases. The remaining 201 employees served as control persons. Additionally, the case group was compared with 22 patients with hypersensitivity to electricity referred to the Occupational and Environmental Health Centre at Huddinge University Hospital.

No association was observed between specific psychosocial work characteristics nor personal traits and hypersensitivity to electricity. Skin symptoms were significantly more often experienced by persons with hypersensitivity to electricity than by persons of the control group. There were no statistically significant differences between cases and controls regarding neurovegetative symptoms. The authors proposed a set of dimensions for characterization of the syndrome hypersensitivity to electricity including skin and neurovegetative symptoms, belief in hypersensitivity to electricity, triggering factors (e.g., visual display unit), duration of symptoms, and behavior (e.g., avoidance of triggering factors).
