Policy Approaches to Reduce Binge Drinking and Impaired Driving Toben F Nelson, ScD Division of Epidemiology and Community Health University of Minnesota Learning Objectives: • Describe the problem of underage drinking within a public health perspective • Describe the value of adopting a public health perspective to combat underage drinking • Identify the ways that a public health perspective is unique • Identify a menu of public health / policy options to reduce underage drinking RISK FACTOR OUTCOME Injuries Liver disease Violence, Sexual Assault GI cancers, GI disorders Alcohol Misuse Unintended Pregnancies Cardiovascular disease Child Neglect Crime, legal costs Lost productivity, absenteeism Alcohol Use Disorders Consequences of Alcohol PREVENTION HARM REDUCTION PERSON CONSUMPTION Probabilistic relationship By drinking event By drinker CONSEQUENCE(S) Underage drinking is part of a larger societal problem with alcohol • 3rd leading cause of preventable death in the US – 4,500 under 21 – 79,000 adults • Youth tend to drink like the adults around them • The causes are the same • The solutions the same too… Binge Drinking among Current Drinkers Male Female Binge Prevalence (%) 70 60 50 40 30 20 10 0 18-20 21-25 26-34 Age Group (years) 35-54 55+ Naimi et al., JAMA, (2003) Percentage of High School Students Who Reported Binge Drinking 11.5% - 21.8% 21.9% - 23.9% 24.0% - 25.1% 25.2% - 30.7% No Data * Had five or more drinks of alcohol in a row within a couple of hours on at least 1 day during the 30 days before the survey. State Youth Risk Behavior Surveys, 2009 Minnesota has a problem Underage >60 alcohol-attributable deaths annually • Mostly acute conditions – Motor vehicle crash – Homicide / Suicide General population >1,100 alcohol-attributable deaths annually • Both acute and chronic conditions – Abuse/Dependence – Liver disease Source: Alcohol-Related Disease Impact (ARDI) CDC Policy Success Ronald Reagan signs national minimum legal drinking age bill, July 1984 “…raising that drinking age is not a fad or an experiment. It's a proven success. Nearly every State that has raised the drinking age to 21 has produced a significant drop in the teenage driving fatalities.” -President Ronald Reagan Effects of Minimum Drinking Age Laws Review of 241 published analyses 1960-2000 135 were of high quality • Outcomes – Alcohol consumption (n=33) – Traffic crashes (n=79) – Other (n=23) Wagenaar & Toomey, 2002 Effects of Minimum Drinking Age Laws Alcohol consumption (n=33) • Higher MDLA – Lower Consumption (n=11; 33%) • Higher MDLA – Higher Consumption (n=1; 3%) Traffic crashes (n=79) • Higher MDLA – Fewer Traffic Crashes (n=46; 58%) • Higher MDLA – More Traffic Crashes (n=0; 0%) Other (n=23) • Higher MDLA – Fewer Alcohol-related problems (n=8; 35%) • Higher MDLA – More Alcohol-related problems (n=0; 0%) Wagenaar & Toomey, 2002 Annual lives saved by 21 MLDA • Based on an average decline in deaths of 13% when individual states raised the MLDA • 890 lives saved in 2006 • Total lives saved - more than 25,000 Source: The Monitoring the Future Study, the University of Michigan Underage Drinking in the U.S. • 10.8 million youth ages 12-20 years in the U.S. reported past-month drinking in 2004, and 7.4 million reported pastmonth binge drinking. • 5,400 children under 16 years start drinking every day in the U.S. • On average, 12-17 year olds report they began drinking at age 14 years. Source: Substance Abuse Mental Health Services Administration, National Survey on Drug Use and Health, 2005 Deaths and YPLL among Youth <21 due to Exposure to Excessive Drinking • 4,500 alcohol-attributable deaths • 274,000 YPLL (60 yrs lost/death) • >95% of deaths and YPLL involved binge drinking. • 1 of 4 deaths among males and 1 of 6 deaths among females age 15 to 20 years. • Three-fourths of the deaths involved young men.

High-Risk Approach Advantages Disadvantages • Intervention tailored/targeted to the individual • Difficult & costly to ID “atrisk” • Clear benefits (when achieved) to the individual • Intuitive • Effects palliative, temporary • Low odds success • Modest benefit to the population Population Approach Advantages Disadvantages • Large population benefits • May limit personal freedoms • Broad target audience • Longer lasting effects • Resistance from invested parties • Counter-intuitive High-Risk & Population Approaches Not Mutually Exclusive You Can Do Both Social Ecology of Drinking What are some mutable factors that can shift the population distribution?
