Study Examines Effects of Cell-Phone Use During and After Pregnancy on Children's Behavior

TIME: Study: Could Cell-Phone Use in Pregnancy Affect Kids' Behavior?, by Meredith Melnick:

Children exposed to cell phones before and after birth were 50% more likely to have emotional or behavior problems by the age of 7, compared with kids who were not exposed to the phones, according to a new study of 28,745 children. The same authors of the new study reached similar conclusions in a previous study conducted in 2008.

The children in the current study were all enrolled in the Danish National Birth Cohort, a large-scale study of 100,000 Danish children born between 1996 and 2002. Researchers from the School of Public Health at the University of California, Los Angeles, used data from surveys that the mothers of the children filled out; questionnaires included standard tests for emotional or behavior problems in children, as well with hyperactivity, inattention and inability to get along with other kids. . . .
