Binge Drinking Boosts Mortality Risk in Older Adults.
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 –
CDC Online Newsroom – Press Release: January 10, 2012.
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
