Symptom Prevalence and Worry about High Voltage Transmission Lines

Abstract

Few studies have documented public perceptions of environmental health risks from exposure to overhead transmission lines. In particular, little information has been provided on the impact of worry on symptom prevalence in residents living adjacent to high voltage transmission lines. The current study assessed symptom prevalence and worry in 152 Orange County female residents living either adjacent to overhead transmission lines or one block away. Forty-five percent of the respondents were either very worried or somewhat worried about the transmission lines and 55% were slightly worried or not worried at all. Results indicated that for those who did not live on the easement level of worry did not affect the prevalence of health problems, For those who lived on the easement, the most worried respondents were more likely to report health problems. Disclosure of health problems may depend more on individuals′ level of worry about rather than proximity to overhead transmission lines. Possible limitations of this study include personality variables such as hypochondriasis which were not assessed, recall bias, and social desirability, The homogeneity of subjects may also limit the generalizability of findings.
