Journal partially peer-reviewed/unclear

Aim of study (acc. to author)

The aim of study conducted in Germany was to investigate whether people living close to mobile telephony transmitter have an increased risk for malignant tumors.

Endpoint/type of risk estimation

Type of risk estimation:
  • incidence
(odds ratio (OR))

Exposure

Assessment

  • list: patient lists of four general practitioners

Exposure groups

Reference group 1 living in the outer circle in the period 1994 - 2004: distance to the next base station more than 400 m
Group 2 living in the inner circle in the period 1994 - 2004: distance to the next base station less than 400 m
Reference group 3 living in the outer circle in the period 1999 - 2004: distance to the next base station more than 400 m
Group 4 living in the inner circle in the period 1999 - 2004: distance to the next base station less than 400 m

Population

  • Group:
    • men
    • women
  • Characteristics: patients of Naila
  • Observation period: 1994 - 2004
  • Study location: Germany (Naila)
  • Data source: PC-based files of four general practitioners
  • Exclusion criteria: residents of a nursing home; living less than 10 years in the inner circle

Study size

Total 967
Other: 34 cancer cases: 18 in the inner circle and 16 in the outer circle
Statistical analysis method:
  • Chi-square test

Conclusion (acc. to author)

320 of 967 residents of Naila have been living in the inner circle at a distance to the next base station of less than 400 m.
The results showed an increased risk for malignant tumors for patients living closer than 400 m to the mobile telephony transmitter compared to patients living further away. In the years 1999 - 2004 the risk for malignant tumors tripled for patients living in the proximity of the mobile telephony transmitter.
