Epidemiological study (observational study)

Association between number of cell phone contracts and brain tumor incidence in nineteen U.S. States.

Published in: J Neurooncol 2011; 101 (3): 505-507

Aim of study (acc. to author)

The association between number of cell phone contracts and brain tumor incidence in nineteen states of the USA was investigated.

Further details

Data on brain tumor incidence were available from the Central Brain Tumor Registry of the USA (CBTRUS) for the time period 2000-2004 whereas mobile phone exposure was assessed by using the cell phone subscriber data from the Governing State and Local Sourcebook 2007.

Endpoint/type of risk estimation

Type of risk estimation:
  • incidence

Exposure

Assessment

  • list: cell phone subscriber data from the Governing State and Local Sourcebook 2007

Population

  • Group:
    • men
    • women
  • Observation period: 2000 - 2004
  • Study location: USA (19 states)
  • Data source: Central Brain Tumor Registry of the USA (CBTRUS)
Statistical analysis method: ( adjustment: )

Conclusion (acc. to author)

A significant correlation between the number of cell subscriptions and brain tumor was found (r=0.950, P < 0.001). In the multiple linear regression model, the effect of cell phone subscriptions was significant (P = 0.017), and independent of the effect of mean family income (P = 0.894), population (P = 0.003) and age (0.499).
The authors concluded that the linear relationship between cell phone subscriptions and brain tumor certainly needs further epidemiology evaluation.
