Northern Ireland mothers will be concerned to learn that babies who go overdue in pregnany are at more risk of ADHD.
The risk of developing Attention Deficit Hyperactivity Disorder is seen as similar to the dangers to children’s health as being born prematurely.
The first study of its kind found that babies born after a pregnancy of 42 weeks were twice as likely to have long-term problems compared to those born at 40 weeks.
The study’s lead author Dr Hanan El Marroun said placentas older than 40 weeks fail to provide the level of nutrients and oxygen they need.
“We were aware of potential complications caused by babies born prematurely but these findings suggest there is also a greater risk of long-term problems among babies born too late,” she said in the Irish Daily Mail
