Use of wireless phones and serum beta-trace protein in randomly recruited persons aged 18-65 years: a cross-sectional study. epidem.

Published in: Electromagn Biol Med 2012; 31 (4): 416-424

Aim of study (acc. to author)

A cross-sectional study was conducted in Sweden to investigate whether use of mobile phones and DECT phones is associated with lower concentrations of human serum beta-trace protein.

Further details

The study is based on the same study population as in Söderqvist et al. (2009). Additionally, data for the 18 -30 year age group were combined with data from two previously studies by Hardell et al. (2010) and Söderqvist et al. (submitted).

Conclusion (acc. to author)

Overall, no statistically significant association between use of mobile phones as well as DECT phones and the serum concentration of beta-trace protein was found, neither with respect to short-term nor long-term use. Age-specific analyses, however, yielded negative associations for long-term use (group 1 and 3) and beta-trace protein in the youngest age group (18-30 years).
