Results from studies evaluating potential effects of prenatal exposure to radio-frequency electromagnetic fields
from cell phones on birth outcomes have been inconsistent. Using data on 55,507 pregnant women and their
children from Denmark (1996–2002), the Netherlands (2003–2004), Spain (2003–2008), and South Korea
(2006–2011), we explored whether maternal cell-phone use was associated with pregnancy duration and fetal
growth.
