Abstract:
Alcohol consumption is one of the important modifiable risk factors for stroke in young adults. The association between the cumulative burden of alcohol consumption and its impact on incident stroke in young adults is unknown. We aimed to investigate the association between cumulative alcohol burden and the risk for stroke among young adults. Methods Using data from the Korean National Health Insurance Service database, patients age between 20 and 39 years, who underwent 4 consecutive annual health examinations between 2009 and 2012, were included. The cumulative alcohol burden score of moderate-to-heavy drinking was evaluated by assigning a score of 1 for alcohol consumption ≥105 g/wk at the health examination each year and calculating the sum of 4 years (0–4). The main outcome was incident stroke and its subtypes, ischemic stroke, and hemorrhagic stroke during the follow-up period. Results Of 1 536 668 patients (mean age of 29.5 years, 71.5% male, and median follow-up of 6-year), 3 153 experienced an incident stroke (incidence rate, 0.37 per 1,000 person-years). After multivariable adjustment, patients with alcohol burden scores of 2, 3, and 4, who consumed more than 105 g/wk of alcohol for 2, 3, and 4 years, demonstrated significantly higher risks for stroke (hazard ratio [HR] 1.19, 95% CI 1.05–1.34 for 2; HR 1.22, 95% CI 1.09–1.38 for 3; HR 1.23, 95% CI 1.10–1.38 for 4) compared with those with a burden score of 0. This positive dose-response relationship was primarily driven by hemorrhagic rather than ischemic stroke. High alcohol burden scores (i.e., 2, 3, and 4) were significantly associated with higher risks for hemorrhagic stroke (HR 1.30, 95% CI 1.10–1.54 for 2; HR 1.42, 95% CI 1.21–1.67 for 3; HR 1.36, 95% CI 1.16–1.59 for 4) compared with a burden score of 0. Discussion Young adults who engaged in moderate-to-heavy drinking demonstrated a higher risk for incident stroke, especially hemorrhagic stroke. Reducing alcohol consumption should be emphasized in young adults with heavy drinking habits as part of any stroke prevention strategy.
