Daily Mail, 6 December 2010

Children exposed to cell phones in the womb and after birth had a higher risk of behavior problems by their seventh birthday, possibly related to the electromagnetic fields emitted by the devices, a new study of nearly 29,000 children suggests.

The findings replicate those of a 2008 study of 13,000 children conducted by the same U.S. researchers. And while the earlier study did not factor in some potentially important variables that could have affected its results, this new one included them, said lead author Leeka Kheifets, an epidemiologist at the School of Public Health at the University of California at Los Angeles.

"These new results back the previous research and reduce the likelihood that this could be a chance finding," said Kheifets. She stressed that the findings suggest, but do not prove, a connection between cell phone exposure and later behavior problems in kids.

The study was published online Dec. 6 in the Journal of Epidemiology and Community Health.
