Patterns of alcohol use and the risk of drinking and driving among US high school students.

Approximately one third of deaths among persons aged 15 to 24 years are the result of motor vehicle-related crashes. Data from a national sample of US high school students were used to assess patterns of alcohol use among adolescents in relation to the risk of drinking and driving. Prevalence and odds ratios were calculated for drinking and driving associated with patterns of alcohol use. Drinking and driving increased with increasing frequency of alcohol use and binge drinking and when alcohol was used in addition to other drugs. Efforts to reduce drinking and driving among adolescents should address underage drinking that is frequent or heavy.
