Aim of study (acc. to author)

A study was conducted in Finland to evaluate self-reported physical symptoms associated with the use of mobile phones and other electrical devices.

Further details

The possible influence of new technical equipment on health was assessed by using open-ended question in questionnaire (qualitative method). Furthermore, the answers should be classified into subgroups based on symptoms or devices.

Endpoint/type of risk estimation

symptoms of discomfort: pain in several joints and back
sleep disturbances
electromagnetic hypersensitivity: self-reported physical symptoms: headache, earache, warmth sensations, skin symptoms
depression, exhaustion at work, substance addiction, anxiety or fear situations

Type of risk estimation:

prevalence

Exposure

- mobile communications
- mobile phone
- personal

Assessment

questionnaire: use of technical devices at work and at leisure: desktop computer, mobile phone and portable or mini-computer

Population

Group:
- men
- women
Age: 18–65 years
Characteristics: working-age population
Observation period: October 2002
Study location: Finland

Type	Value
Total	15,000
Participants	6,121

Conclusion (acc. to author)

1300 out of 6121 participants answered the open-ended question "other observations concerning technology and health". Three categories were identified: 1) respondents with different self-reported symptoms in association with using mobile phones, 2) respondents with skin symptoms when they stayed in front of a computer screen for a long period, and 3) respondents who somehow mentioned physical symptoms associated with the use of mobile phones or other electrical devices.
The prevalence of self-reported symptoms in association with the use of mobile phones and other electrical devices was 0.7 %.
