Microwaves and wireless devices can increase the risk of obesity in unborn children, a new study reveals.
Researchers have found magnetic fields from these sorts of appliances can increase the risk of an unborn baby growing up to be obese by almost 70 per cent.
"Pregnancy is a critical developmental
stage that is among the most vulnerable periods to environmental exposures," said lead author, De-Kun Li, a perinatal epidemiologist.
"These findings indicate that electromagnetic fields, from microwave ovens to countless wireless devices, may be contributing to childhood obesity risk," Dr Li said.
Mothers participating in the research, published in the journal Scientific Reports, carried a meter that measured the magnetic field they were exposed to while they were carrying their baby. The growth of 733 babies born to these women was then analysed. Researchers tracked every child for 11 years, collecting height and weight measurements.
