Moderate Exercise May Cut Women's Stroke Risk

Brisk walking, tennis and other types of moderate exercise may lower a woman's stroke risk by one-fifth, a new study says.

Being more active also offset the increased stroke risk linked with using hormone replacement therapy to treat the symptoms of menopause, the study found.

The researchers looked at the number of strokes that occurred among nearly 133,500 women in the California Teachers Study, which ran from 1996 to 2010.

Women who said they did moderate physical activity in the three years before enrolling in the study were 20 percent less likely to have a stroke than those who were inactive. 

"I was surprised that moderate physical activity was most strongly associated with a reduced risk of stroke," study author, a professor in the department of population sciences.

"More strenuous activity, such as running, didn't further reduce women's stroke risk. Moderate activity, such as brisk walking, appeared to be ideal in this scenario," she added.

The researchers also found that postmenopausal women taking hormone therapy were 30 percent more likely to have a stroke than those who never used hormone therapy, but moderate exercise helped reduce this increased risk. And after women stopped taking hormone therapy, their risk began to fall.

The findings show that women need to include physical activity into their daily routine, Wang said.

"You don't have to do an extreme boot camp. The types of activities we're talking about are accessible to most of the population," and include power walking and recreational tennis, she noted.

While 87 percent of the women in the study were white, the results likely apply to women in other racial/ethnic groups, Wang added.

Research presented at medical meetings should be viewed as preliminary until published in a peer-reviewed journal.

And the study only found an association between exercise and reduced stroke risk. It did not prove cause-and-effect.
