They examined the association between episodic heavy drinking and total mortality among 446 regular moderate drinkers aged 55 to 65 years at baseline. Moderate drinking was defined as up to 1 standard drink per day for women and 2 for men.
Of the 446 adults, 74 engaged in episodic heavy drinking, defined as 4 or more drinks on 1 occasion for women and 5 for men.
During the course of 20 years, the death rate was higher in the moderate drinkers who binged (61%, 45 deaths) than in moderate drinkers who did not binge (37%, 137 deaths).
Although more men than women died during the 20-year period, the distribution of deaths across alcohol consumption groups was similar for women and men (P = .76).
In multiple logistic regression analyses, after adjusting for all covariates as well as overall alcohol consumption, moderate drinkers who engaged in episodic heavy drinking had more than 2 times higher odds of 20-year mortality in comparison with regular moderate drinkers (odds ratio, 2.13; 95% confidence interval, 1.14 – 3.97; P< .05).
And from the CDC –
Binge drinking statistics from the CDC estimate more than 38 million US adults binge drink an average of 4 times a month and the most drinks they consume on average is 8. The report found that binge drinking is more common among households with incomes ≥$75,000, but the largest number of drinks consumed per occasion is highest among households with incomes of <$25,000
