According to recent research, compared to married people, divorced people drink more and in more dangerous ways including binge drinking.
Divorced people tend to engage in more alcohol related risky behaviours and also have a higher alcohol related mortality.
The recent study which was published in the American Journal of Psychiatry and based on a Swedish population of 950 000 people born between 1960 and 1990, who had no alcohol use disorder diagnosis prior to marriage, found that after divorce the rates of first time alcohol use disorder increased in both men and women. In men it increased six times and in women it increased seven fold.
