CHICAGO (September 16, 2013)--Almost 1 in 10 U.S. high school seniors has engaged in recent extreme binge drinking, which means downing at least 10 drinks in a row, and the rate barely budged over six years, a new report says.
Binge drinking at least five in a row has mostly declined in recent years among teens, but researchers say the trend for more extreme drinking is worrisome.
The most extreme level is 15 or more drinks in a row.
That rate was almost 6 percent and it didn't change from 2005 to 2011.
The report is an analysis of survey results that the University of Michigan does for the National Institute on Drug Abuse and is based on classroom questionnaires given to more than 16,000 high school seniors.
The report was published online Monday in JAMA Pediatrics.
