Global suicide prevention should focus more on alcohol use disorders

In fact, alcohol use disorder was the most frequent DSM-III-R axis I psychiatric disorder (mood, psychotic, substance use, etc) in the studies cited. According to a meta-analysis of mortality studies, the lifetime risk of suicide is 7% for alcohol dependence.4 Interestingly, in a recently reported time series analysis a significant positive relation between per capita alcohol consumption and gender and age specific suicide rates was revealed most often in dry (low consumption) cultures (northern Europe) and least often in wet cultures (southern Europe).5 How may we use this link in devising strategies to prevent suicide?
