Study type: Medical/biological study (observational study)

Effect of electromagnetic field induced by radio frequency waves at 900 to 1800 MHz on bone mineral density of iliac bone wings. med./bio.

Published in: J Craniofac Surg 2009; 20 (5): 1556-1560

Aim of study (acc. to author)

To study the effects of electromagnetic fields emitted from mobile phones (900 to 1800 MHz) on the bone mineral density of the human iliac bone wings (part of hip bone), which are the most common carriage sites for cellular phones.

Background/further details

A total of 150 male volunteers were included (mean age was 31.85 years). The iliac bone wings of participants were separated into two groups: exposed side (group 1) and unexposed side (group 2). 122 of all volunteers were carrying their cell phones on their right iliac wings, whereas 28 were carrying their mobile phones on their left iliac wings. The mean daily carriage duration was 14.7 hours, and the mean duration for cellular phone use was 6.2 years.

Main outcome of study (acc. to author)

The values of bone mineral density of group 1 were slightly lower than those from group 2, but there was no statistically significant difference between the groups. In addition, the mean values of group 1 were not as low as those measured in osteoporosis cases.
