A study was conducted in UK to investigate the association between power lines and recurrent headache and depressions.
Questionnaires were delivered personally to 120 houses in the· study area and to 120 houses in the control area and three days later the questionnaires were collected.
Group | Description |
---|---|
Reference group 1 | distance from power line: > 4,8 km |
Group 2 | distance from power line: < 20 m |
Group 3 | distance from power line: 20 - 40 m |
Group 4 | distance from power line: 40 - 60 m |
Group 5 | distance from power line: 60 - 80 m |
Group 6 | distance from power line: 80 - 100 m |
Type | Value |

Participants | 132 |
Participation rate | 60 % |
15 out of 132 participants of the exposed group reported recurrent headache or migraine, compared with 1 of 94 in the control group. 10 participants reporting recurrent headache lived in houses in a distance of 60-80 m to the power line. Analysis revealed that people who are younger, live close to a power line and have more days off work are significantly more likely to suffer from headaches or migraines. The sex of the person and the number of years resident in the house did not affect the incidence of headaches. Additionally, 9 patients in the exposed group reported depression (of whom 7 lived within 40 m of the power line) and one in the control group.
