Moderate Alcohol Drinking Reduces Stroke Risk in Women

This study of 83,578 women over a period of 26 years found that the risk of strokes was significantly lower among those who consumed alcohol at light to moderate levels compared to non-drinkers or abstainers.

The subjects were participants in the Nurses' Health Study who were free of cardiovascular disease at the beginning if the study. Their alcohol consumption was assessed every four years. Stroke and potential cofounders were assessed biannually.

Women who consumed one drink per day had a reduced risk of stroke of about one-fifth. The risk of stroke didn't show any evidence of beginning to increase until consumption was over about three drinks per day.

Light and moderate drinking significantly reduced both ischemic stroke (caused by an atherosclerotic obstruction or blood clot in an artery) or hemorrhagic stroke (caused by bleeding in the brain).

These findings are consistent with a study of over 22,000 male physicians who were participants in the Physicians Health Study and with much other research demonstrating a protective effect of light and moderate drinking on the risk of developing strokes.

The research report is published in Stroke, an official publication of the American Stroke Association.
