Alcohol use and risk of intracerebral hemorrhage

OBJECTIVE: To analyze the dose-risk relationship for alcohol consumption and intracerebral hemorrhage (ICH) in the Ethnic/Racial Variations of Intracerebral Hemorrhage (ERICH) study.

METHODS: ERICH is a multicenter, prospective, case-control study, designed to recruit 1,000 non-Hispanic white patients, 1,000 non-Hispanic black patients, and 1,000 Hispanic patients with ICH. Cases were matched 1:1 to ICH-free controls by age, sex, race/ethnicity, and geographic area. Comprehensive interviews included questions regarding alcohol consumption. Patterns of alcohol consumption were categorized as none, rare (/=1 drink per month and 2 drinks per day and /=5 drinks per day). ICH risk was calculated using the no-alcohol use category as the reference group.

RESULTS: Multivariable analyses demonstrated an ordinal trend for alcohol consumption: rare (odds ratio [OR] 0.57, p < 0.0001), moderate (OR 0.65, p < 0.0001), intermediate (OR 0.82, p = 0.2666), and heavy alcohol consumption (OR 1.77, p = 0.0003). Subgroup analyses demonstrated an association of rare and moderate alcohol consumption with decreased risk of both lobar and nonlobar ICH. Heavy alcohol consumption demonstrated a strong association with increased nonlobar ICH risk (OR 2.04, p = 0.0003). Heavy alcohol consumption was associated with significant increase in nonlobar ICH risk in black (OR 2.34, p = 0.0140) and Hispanic participants (OR 12.32, p < 0.0001). A similar association was not found in white participants.

CONCLUSIONS: This study demonstrated potential protective effects of rare and moderate alcohol consumption on ICH risk. Heavy alcohol consumption was associated with increased ICH risk. Race/ethnicity was a significant factor in alcohol-associated ICH risk; heavy alcohol consumption in black and Hispanic participants poses significant nonlobar ICH risk.
