Binge Drinking: A Rite of Passage That's All Wrong
Aug. 25, 2000 -- In the process of giving new meaning to the term "party animal," a Duke researcher has come up with some sobering news for thousands of students heading off to college where binge drinking is an all too common activity. A study done on binge-drinking rats may help prove someday that such drinking among adolescent humans not only may be harmful to them while they're young, but also remain harmful to them as adults.
The study, in the August issue of Alcoholism: Clinical and Experimental Research,shows evidence that binge drinking affects the brain's response to alcohol later in life, and adolescents are especially vulnerable to the behavior because their brains are still developing, the researchers suggest.
To explore the effects of binge drinking, study author Aaron White, PhD, compared rats that were repeatedly exposed in a "binge pattern" to large amounts of alcohol in adolescence to those who were not. When all the rats were adults, their learning skills were tested in a classic maze. The two groups of rats responded similarly when sober, but while under the influence of alcohol, the adolescent binge drinkers had significantly larger memory impairments than those who were not given alcohol during adolescence.
"There's more to learn about humans, but the findings are still a cause for concern," says White, a psychiatric researcher at Duke University in Durham, N.C.
Binge drinking is defined as five drinks in one sitting for men, and four for women. A recent study done by the Harvard School of Public Health showed that 44% of 14,000 students polled described drinking habits at one time that fit the description of binge drinking. The end result of all that drinking is often more than just a mere hangover.
"Binge drinkers are much more likely to miss classes, experience injuries, and damage property," says Mark Goldman, PhD, director of the alcohol and substance abuse research institute at the University of South Florida. "Because it's also strongly linked with car crashes, binge drinking accounts for 60 deaths a year."
