From the “Third Variable” department:
Researchers at my alma mater, UCLA, have conducted a study that shows a strong correllation between cell phone use by a parent (pre- and post-natal) and behavior problems in their kids. Their findings:
Children with both prenatal and postnatal cell phone exposure were 80 percent more likely to have abnormal or borderline scores on tests evaluating emotional problems, conduct problems, hyperactivity, or problems with peers.
Note that this is a correllative study and indicates a direction to be looked into. It did not test, and does not address, the effect of radio frequency exposure on fetuses or what have you. It put cell phone use by parents and kids versus reported behavioral problems and found that they are somehow related. Make with it what you will!
