FEATURE ARTICLE:
Recall bias in the assessment of exposure to mobile phones

Published in: J Expo Sci Environ Epidemiol 2008 (epub ahead of print)

Summary

This is an exposure assessment validation study of the INTERPHONE project, which is investigating the possible association of brain tumour risk and mobile phone use. The INTERPHONE case-control studies assess exposure through the subjects’ reports of past phone use. To validate this method, phone records of 212 cases and 296 controls were collected from network operators in three INTERPHONE countries over an average of 2 years, and compared with mobile phone use reported at interview. The authors conclude that there was little evidence for differential recall errors overall or in recent time periods. However, apparent overestimation by cases in more distant time periods could cause positive bias in estimates of disease risk associated with mobile phone use.

Use of wireless telephones and self-reported health symptoms: a population-based study among Swedish adolescents aged 15-19 years

By: Soderqvist F et al
Published in: Environ Health 2008; 7 (1): 18

Summary

Cross-sectional study assessing the use of mobile and cordless telephones and associated self-reported health symptoms among adolescents (15-19 years) in Sweden. The authors report that almost all subjects in the study used either a mobile or cordless phone, with girls more than boys. The authors also report that perceived health and certain health symptoms seemed to be related to mobile or cordless phone use. However, the authors warn that the findings on health effects should be interpreted with caution since bias and chance findings due to multiple testing might have influenced the results.

Studying the effects of mobile phone use on the auditory system and the central nervous system: a review of the literature and future directions

By: Kaprana AE et al
Published in: Eur Arch Otorhinolaryngol 2008 (epub ahead of print)

Summary

Review of studies on the effects of mobile phone use on the auditory and central nervous systems. The authors conclude that no safe conclusions can be drawn regarding the potential harmful effects of mobile phone use.

Variability analysis of SAR from 20 MHz to 2.4 GHz for different adult and child models using finite-difference time-domain

By: Conil E et al
Published in: Phys Med Biol 2008; 53 (6): 1511 – 1525

Summary

Study assessing the variability of anthropomorphic voxel models used in numerical radiofrequency dosimetric research. The authors conclude that for adult models, compliance with the ICNIRP reference levels ensures compliance with basic restrictions, but for child models, the whole-body-averaged SAR exceeds the basic restrictions by up to 40%.

A new electromagnetic exposure metric: High frequency voltage transients associated with increased cancer incidence in teachers in a California school

By: Milham S and Morgan LL
Published in: Am J Ind Med 2008 (epub ahead of print)

Summary

Investigation of the high incidence of cancer among teachers at a school in the US and it’s possible association with high frequency voltage transients. The authors conclude that the cancer incidence was unusually high and is strongly associated with high frequency voltage transients.

Effect of extremely low frequency magnetic field on antioxidant activity in plasma and red blood cells in spot welders

By: Sharifian A et al
Published in: Int Arch Occup Environ Health (epub ahead of print)

Summary

In this study the antioxidant activity in plasma and red blood cells of 46 spot welders who are occupationally exposed to ELF magnetic fields was compared to a control group. The authors conclude that ELF magnetic fields could influence the antioxidant activity even at the recommended levels of exposure.
