Alcohol use has several consequences and is one of the variables that increase risk of suicide. This meta-analysis was performed using cohort studies to clarify the association of alcohol use and suicide. Scientific sources were reviewed regarding the keywords. After screening, thirty cohort studies were identified for the meta-analysis. The analysis was performed based on the random effects and subsequent analysis of the subgroups, based on various variables. Analysis of the results showed that there is a relationship between alcohol use and suicide. Risk Ratio (RR) between alcohol use and suicide was 1.65. In men, pooled RR was 1.56 with 95% CI = 1.20-2.03, and in women, the pooled RR was equal to 1.40 with 95% CI = 1.11-1.77. Overall, the findings indicate that alcohol use is a risk factor for suicide. Therefore, it seems that prevention and control of alcohol use can be effective in promoting mental health.
