Alcohol Consumption Per Capita and Suicide

Is alcohol consumption per capita associated with suicide mortality and, if so, does the association differ by sex?This meta-analysis included 13 studies and found that a 1-L increase in alcohol consumption per capita was associated with a 3.59% increase in the suicide mortality rate. There was no evidence of a sex difference in this association.These findings suggest that alcohol consumption per capita may be a useful target to consider within comprehensive national suicide prevention strategies.
