Fact Sheet

Drinking Levels among Youth
The 2009 Youth Risk Behavior Survey5 found that among high school students, during the past 30 days

•42% drank some amount of alcohol.
•24% binge drank.
•10% drove after drinking alcohol.
•28% rode with a driver who had been drinking alcohol.
Other national surveys indicate

•In 2008 the National Survey on Drug Use and Health reported that 28% of youth aged 12 to 20 years drink alcohol and 19% reported binge drinking.6
•In 2009, the Monitoring the Future Survey reported that 37% of 8th graders and 72% of 12th graders had tried alcohol, and 15% of 8th graders and 44% of 12th graders drank during the past month.7

Dangerous Effects on the Body

Brain Effects—Scientists currently are examining just how alcohol affects the developing brain, but it’s a difficult task. Subtle changes in the brain may be difficult to detect but still have a significant impact on long-term thinking and memory skills. Add to this the fact that adolescent brains are still maturing, and the study of alcohol’s effects becomes even more complex. Research has shown that animals fed alcohol during this critical developmental stage continue to show long-lasting impairment from alcohol as they age (47). It’s simply not known how alcohol will affect the long-term memory and learning skills of people who began drinking heavily as adolescents.

Liver Effects—Elevated liver enzymes, indicating some degree of liver damage, have been found in some adolescents who drink alcohol (48). Young drinkers who are overweight or obese showed elevated liver enzymes even with only moderate levels of drinking (49).

Growth and Endocrine Effects—In both males and females, puberty is a period associated with marked hormonal changes, including increases in the sex hormones, estrogen and testosterone. These hormones, in turn, increase production of other hormones and growth factors (50), which are vital for normal organ development. Drinking alcohol during this period of rapid growth and development (i.e., prior to or during puberty) may upset the critical hormonal balance necessary for normal development of organs, muscles, and bones. Studies in animals also show that consuming alcohol during puberty adversely affects the maturation of the reproductive system (51).
