The concentration of β-trace protein decreased with increasing years of wireless phone use, but a 30 min experimental exposure to an 890-MHz GSM signal showed no statistically significant change.

Plain English Summary

Summary written for general audiences

Researchers studied the concentration of β-trace protein in blood in relation to emissions from wireless phones in 62 persons aged 18-30 years. The concentration of β-trace protein decreased with increasing number of years of use of a wireless phone, yielding a negative β coefficient of -0.32 with a 95% confidence interval of -0.60 to -0.04. Cumulative use in hours also gave a negative β coefficient, although not statistically significant. Forty of the 62 persons participated in an experimental study with 30 min exposure to an 890-MHz GSM signal, and no statistically significant change of β-trace protein was found. In a similar study of the remaining 22 participants with no exposure, β-trace protein increased significantly over time, probably due to a relaxed situation.

Why This Matters

The authors suggest that EMF emissions may down-regulate the synthesis of β-trace protein. They propose that this mechanism might be involved in sleep disturbances reported in persons exposed to RF fields. The results must be interpreted with caution because use of mobile and cordless phones was self-reported. Awareness of the exposure condition in the experimental study may have influenced β-trace protein concentrations.
