Young children who snore could be at greater risk of becoming hyperactive later than those who sleep quietly, US researchers reported on Friday (July 1). Their study, published in the journal Sleep, strengthens earlier conclusions linking sleep disorders and hyperactivity and also seems to confirm that it is the snoring that comes first.
In 2002, a University of Michigan team reported that among 229 children studied, those who snored regularly were twice as likely to later be hyperactive or have attention issues than non-snorers. For boys under the age of 8, the rate was four times higher.
