Association between high voltage overhead transmission lines and mental health: A cross-sectional study. epidem.

Published in: Bioelectromagnetics 2006; 27 (6): 473-478

Aim of study (acc. to author)

The association between high voltage overhead transmission lines (HVOTL) and mental health among mothers was investigated in a cross-sectional study in Japan.

Further details

The distance from the residence to the closest high voltage overhead transmission line was categorized in groups up to 100 m, 101 - 300 m, and more than 300 m. Mental Health score below 52 points in the SF-36 Health Survey was classified as poor mental health status.

Conclusion (acc. to author)

Only 10 women lived in residences closer than 100 m from a high voltage overhead transmission line. The Mental Health status was not significantly associated with the distance between the subject's residence and the closest high voltage overhead transmission line.

Limitations (acc. to author)

The participation rate was low (23 %). Data on the length of time that the subjects lived at their current residence were not collected.
