CHICAGO (Reuters) - Older people who have significant trouble staying
awake during the day have more than four times the normal risk of
having a stroke, U.S. researchers said on Thursday.

They also found a higher risk of heart attacks and other
cardiovascular problems in seniors who regularly nod off during the
day without planning to.

"Even when we controlled for things like hypertension, diabetes,
physical activity, obesity and socioeconomic status, we found that
people who had significant daytime dozing were much more likely to end
up with stroke," said Bernadette Boden-Albala of Columbia University
in New York.

Her study of 2,153 adults with an average age of 73 found the risk of
stroke was 2.6 times greater for those classified as doing "some
dozing" during the day compared to those with "no dozing." Those in
the "significant dozing" group had a 4.5 times greater risk.

The study, presented at an American Stroke Association conference in
New Orleans, is one of the first to look at the relationship between
unplanned napping and "vascular events" such as stroke.
