College Alcohol Study The younger college students were when first drunk, the more likely they will experience in college: • Alcohol Dependence • Drive after drinking • Alcohol related injury • Unplanned and unprotected sex after drinking Source: Hingson, Heeren, Winter. J. Studies on Alcohol 2003, Pediatrics 2003
CDC Youth RiskBehavior Survey 2003 • 28% of high school students start to drink before age 13. • They are 7 times more likely by age 17 to binge frequently (5 or more drinks/6 or more times per month). • There are over 1 million frequent bingers in high school.
Youth Risk Behavior Survey2003 • Frequent binge drinkers compared to abstainers in high school were much more likely to: • Ride with a drinking driver • Drive after Drinking • Never wear safety belts • Carry weapon • Carry gun • Be injured in a fight • Be injured in a suicide attempt • Be forced to have sex • Had sex with 6 or more partner • Have unprotected sex • Been or gotten someone pregnant • Use Marijuana • Used Cocaine • Ever injected drugs
Youth Risk Behavior Survey2003 • Frequent binge drinkers compared to abstainers in high school were much more likely in the past month to: Drink at school 31% vs. 0% Use marijuana at school 29% vs. 1% Earned mostly D’s and F’s in 13% vs. 4% school within the past year
Conclusion • In the U.S. there is an urgent need to expand and improve prevention, screening and treatment programs and policies to reduce alcohol related harm • Persons under 21 • Among college students • Persons of similar ages not in college
Interventions • Individually oriented • Environmental • Comprehensive Campus/ Community Interventions
GentilelloBrief Motivational Alcohol Intervention in a Trauma CenterAnnals of Surgery, 1999 • 46% of injured trauma center patients age 18 and older screened positive for alcohol problems. • Half (N=336) randomly allocated to receive 30 minute brief intervention to reduce risky drinking and offers links to alcohol treatment
GentilelloBrief Motivational Alcohol Intervention in a Trauma CenterAnnals of Surgery, 1999 • Reduced alcohol consumption by an average 21 drinks per week at 1 year follow up • 47% reduction in new injuries requiring treatment in ED • 48% reduction in hospital admissions for injury over 3 years • 23% fewer drunk driving arrests
Brief Alcohol Intervention for Older Adolescents J. Consulting and Clinical Psychology Monti et al. (1999) • 94 ED patients, mean age 18.4, injured after drinking • Half randomly allocated to a 35-40 minute motivational intervention to reduce drinking and related risky behaviors such as DWI

PurposeTo assess whether an earlier drinking onset is related to: • Unintentional injuries under the influence of alcohol • Motor vehicle crashes because of drinking • Physical fights after drinking - ever in the respondent’s life - during the year prior to the survey
Figure 2: Ever in a Physical Fight While or After Drinking According to Age of Drinking Onset, National Longitudinal Alcohol Epidemiologic Survey Odds Ratio and Confidence Intervals Age Started Drinking P<.001 Controlling for Age, Gender, Black, Non Hispanic, Hispanic, other, education, marital status, current, past, never smoke current, past, never use drugs, family history of alcoholism, current, past, never alcohol dependent, frequency drank 5+ during respondent’s period of heaviest drinking
Why Are These Findings Important? Injuries are the leading cause of death among youth 1-34 • Unintentional injuries #1 1-44 • Intentional injuries #2 8-34 Source: CDC
Why Are These Findings Important? Alcohol is involved over 50,000 injury deaths annually Over half under age 44 Source G. Smith et. al 1999
Legislation to Reduce AlcoholRelated Traffic Deaths: • Legal drinking age of 21 All States • Criminal per se laws All States • Administrative license revocation 40 States • Mandatory assessment and treatment 32 States • Primary enforcement safety belt 21 States • Zero tolerance for drivers under 21 All States • .08% Criminal per se BAC level All States
BAC and Impairment Concentrated Attention, Speed Control, Braking, Steering, Gear Changing, Lane Tracking, Judgement Tracking, Divided Attention, Coordination, Comprehension, Eye Movement Simple Reaction Time, Emergency Response Choice Reaction Time • Key driving functions are impaired at levels as low as .02-.04%.

Relative Risk of Fatal CrashDrivers Age 16-19 and 20+ As a function of BAC 16-19 y.o. 20+ y.o. • The risk of fatal crash increases more with each drink among young drivers than drivers age 20 and older. Source: Simpson, H. 1989
