Objective. To evaluate a possible association of glioma or meningioma with
use of cellular telephones, using a nationwide population-based case-control
study of incident cases of meningioma and glioma.
Methods. The authors
ascertained all incident cases of glioma and meningioma diagnosed in Denmark
between September 1, 2000, and August 31, 2002.
They enrolled 252 persons
with glioma and 175 persons with meningioma aged 20 to 69.
The authors also
enrolled 822 randomly sampled, population-based controls matched for age and
sex.
Information was obtained from personal interviews, medical records
containing diagnoses, and the results of radiologic examinations.
For a
small number of cases and controls, the authors obtained the numbers of
incoming and outgoing calls.
They evaluated the memory of the respondents
with the Mini-Mental State Examination and obtained data on socioeconomic
factors from Statistics Denmark.
Results. There were no material
socioeconomic differences between cases and controls or participants and
non-participants.
Use of cellular telephone was associated with a low risk
for high-grade glioma (OR, 0.58; 95% CI, 0.37 to 0.90).
The risk estimates
were closer to unity for low-grade glioma (1.08; 0.58 to 2.00) and
meningioma (1.00; 0.54 to 1.28).
Conclusion. The results do not support an
association between use of cellular telephones and risk for glioma or
meningioma.
