Light-to-moderate alcohol consumption is associated with a lower risk of stroke in women, a new study has claimed.
Monik Jimenez ScD from Brigham and Women's Hospital (BWH) examined data from 83,578 female participants in the Nurses' Health Study.
They looked at data of women who had no evidence of cardiovascular disease or cancer at baseline and followed them for up to 26 years. Participants provided information on diet, including self-reported alcohol consumption, lifestyle factors and stroke events.
There were 2,171 incidents of stroke – 1,206 were ischemic strokes, 363 hemorrhagic strokes, and 602 were of an unknown or probable type. An ischemic stroke occurs when blood flow to the brain is blocked. A hemorrhagic stroke occurs when a blood vessel bursts in the brain.
Approximately 30 per cent of women reported that they never drank alcohol, 35 per cent reported very low levels of consumption, 37 per cent drank moderately, and only 11 per cent of women reported drinking more than the equivalent of one mixed drink per day on average.
In the study, low consumption was considered less than 4.9 grams daily (less than half a glass of wine per day). Moderate consumption was considered 5 to 14.9 grams daily (half to one-and-a-half glasses of wine, one serving of a mixed drink, or one beer).
After analysing the data, the researchers saw that women who consumed low to moderate amounts of alcohol had a lower risk of total stroke compared to women who never drank. Higher levels of alcohol intake were not associated with reduced risk of stroke.
The researchers speculate on several scenarios that may explain alcohol's ability to reduce stroke risk. Alcohol may have components to prevent blood clots and cholesterol from building up in the arteries, both of which can lead to stroke.
Higher levels of alcohol intake may increase the risk of high blood pressure and atrial fibrillation, which are risk factors for stroke.
