A new study is suggesting that excessive drinking may lead middle-aged adults to a higher risk of stroke.
Heavy alcohol consumption has long been linked to increased likelihood of developing diabetes, but this recent study from a team of researchers from Czech Republic’s St. Anne’s University Hospital revealed that the risk of getting a stroke is much higher. The study looked into the health profiles of close to 12,000 twins of the same sex registered in the Swedish Twin Registry from 1967 to 1970, and followed them up until 2010 to reevaluate their health.
After the 43-year follow-up, about 30 percent of the respondents experienced a stroke. Of this group, the researchers separated them into three categories according to their level of daily drinking: half a glass of alcoholic beverage (light drinker), up to two glasses (moderate drinker), or more than two (heavy drinker). Results showed that those who drunk alcohol heavily were 34 percent more likely to suffer a stroke than those who drank light. Meanwhile, those who continued to drink above 50 years of age had an increased risk of stroke roughly five years earlier than the people who drank up to half a glass daily.
Study lead author Pavla Kadlecová, who works as statistician for the hospital’s International Clinical Research Center, highlighted the impact of their discovery on the prevention of stroke. “We now have a clearer picture about these risk factors, how they change with age and how the influence of drinking alcohol shifts as we get older. For mid-aged adults, avoiding more than two drinks a day could be a way to prevent stroke in later productive age (about 60s),” Kadlecová said in a news report.
