Walking May Cut Stroke Risk in Older Men

British study suggests the number of weekly hours walked, not how fast, is what matters

But nicer doesn't necessarily equal healthier,

THURSDAY, Nov. 14 (HealthDay News) -- Older men may reduce their risk of stroke by taking a daily walk. And that walk doesn't have to be especially brisk, British researchers report.

The new study suggests that walking for an hour or two might lower the risk of stroke by as much as one-third, and walking three hours or more daily might cut the risk by two-thirds.

"Stroke is a major cause of death and disability and it is important to find ways to prevent stroke, especially in older people who are at high risk," said lead researcher Barbara Jefferis, a senior research associate in the department of primary care and population health at University College London.

This study suggests that maintaining an active lifestyle, specifically by walking, could prevent stroke in older adults, she said.

"Getting into the habit of walking every day for at least an hour could protect against stroke," Jefferis said. "Walking could be for transport, such as doing errands and going to the shops, walking around indoors as well as walking for leisure, such as walking in a park."

Moreover, it doesn't seem to matter how fast a man walks. Just walking does the trick, regardless of pace, she said.

The report was published Nov. 14 in the online edition of the journal Stroke.

Dr. Ralph Sacco, chairman of neurology at the University of Miami Miller School of Medicine, said this is yet another study that confirms the benefits of exercise in regard to stroke prevention.

Sacco said physical activity in general, not just walking, is important in reducing stroke risk for both men and women.

"All forms of physical activity, including walking, can promote ideal [heart] health and reduce stroke risk," he said.

Study author Jefferis also spoke out in favor of a variety of activities.

"We know that physical activity has benefits for a wide range of mental and physical health outcomes," she said. "Aiming for 150 minutes per week of moderate physical activity, which includes walking at a brisk pace or light gardening, or 75 minutes per week of vigorous activities, such as jogging or tennis ... would protect against heart disease and diabetes, as well as protecting against stroke."

Although the study found an association between greater weekly walking time and lower stroke risk in men, it did not establish a cause-and-effect relationship.

For the study, Jefferis's team collected data on nearly 3,500 healthy men aged 60 to 80 who were taking part in a larger heart study involving 24 British towns. The men were asked how far they walked each week.

The researchers divided the men into five groups: those who walked zero to three hours a week, four to seven hours a week, eight to 14 hours a week, 15 to 21 hours a week and more than 22 hours a week.
