A team of researchers at the University of Michigan is looking at the prevalence and predictors of high school age binge drinking. In a study of over 16,000 US high school seniors, over 20% reported binge drinking in the past two weeks—that’s 4 or more drinks in a row for women, and 5 for men. And then there’s extreme binge drinking: ten and half percent said they consumed 10 or more drinks in a row and over 5.6% consumed 15 or more drinks in row. Males were worse than females, typically, and kids of college-educated parents were more likely to binge drink but notextreme binge drink. Extreme binge drinking rates have held steady since 2005 and researchers say we need to develop effective prevention and intervention strategies.
