A new link between use of
mobile phones by
pregnant women and problems such as
hyperactivity in their children has been identified by researchers in
California and
Denmark .
A study of over 13,000 children in Denmark born in the late 1990s found mothers using their
mobile phones between two and three times a day were 54 per cent more likely to give birth to offspring with
behavioural problems .
The research also suggested that the risk is further increased to 80 per cent if the child then uses a mobile themselves before the age of seven.
Scientists behind the research at the
universities of California, Los Angeles (UCLA) and Aarhus, Denmark, said the results "should be interpreted with caution" and double-checked by further studies.
But they added that the findings would "have major public
health implications" if proved to be real.
The first-of-its-kind study raises renewed questions over the
safety of mobile phones, which in the past has been linked with numerous health concerns such as increasing the risk of brain
cancer .
