  1. Policy Approaches to Reduce Binge Drinking and Impaired Driving Toben F Nelson, ScD Division of Epidemiology and Community Health University of Minnesota

  2. 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

  3. 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

  4. Consequences of Alcohol PREVENTION HARM REDUCTION PERSON CONSUMPTION Probabilistic relationship By drinking event By drinker CONSEQUENCE(S)

  5. 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…

  6. Binge Drinking amongCurrent Drinkers Naimi et al., JAMA, (2003)

  7. 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

  8. 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

  9. Ronald Reagan signs national minimum legal drinking age bill, July 1984 Policy Success “…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

  10. Effects of Minimum DrinkingAge 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

  11. Effects of Minimum DrinkingAge 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

  12. 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

  14. 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 past-month 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

  15. 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. CDC: ARDI Web Site (www.cdc.gov/alcohol), 2007

  16. Onset of drinking Early start (before age 15) associated with: • Alcohol use • Other substance use • Alcohol-related health and social consequences • Abuse, Dependence, Alcoholism …in adulthood

  19. Surgeon General’s Recommendations • Enforce all policies and laws against underage drinking and publicize these efforts • Gain public support for enforcing underage drinking laws Source: Office of the US Surgeon General (2007)

  20. Some Distinctions between Public Health and Medicine H Fineberg, Harvard School of Public Health, 1990 http://www.hsph.harvard.edu/about.html

  21. The Strategy of PreventionAn example

  22. The Prevention Paradox Greatest risk health harms among extreme drinkers. HOWEVER, few extreme - many “moderate” drinkers. “Moderate” drinking also carries risks Vast majority of health harms in a community arise from moderate or low consumption. Greatest health gains from incrementally moving majority. Rose (1985); Rose (1992)

  23. Risk of injury, by usual number of drinks(past 30 days) Weitzman & Nelson (2004)

  24. Evidence for findings regardless of: consumption measure Usual drinks Drinking frequency Frequency of drunkenness Negative social/health consequence 14 different outcomes Only the risk trajectory varied The Prevention Paradox Weitzman & Nelson (2004); Wechsler & Nelson (2006)

  25. The Prevention Paradox “A prevention measure that brings large benefits to the community affords little to each participating individual” Geoffrey Rose , 1998

  26. High-risk & Population Approaches High-risk: change extreme, high-risk individuals, treatment Population: change majority, the conditions that shape everyone’s behavior.

  27. High-Risk Approach Advantages Intervention tailored/targeted to the individual Clear benefits (when achieved) to the individual Intuitive Disadvantages Difficult & costly to ID “at-risk” Effects palliative, temporary Low odds success Modest benefit to the population

  28. Population Approach Advantages Large population benefits Broad target audience Longer lasting effects Disadvantages May limit personal freedoms Resistance from invested parties Counter-intuitive

  29. High-Risk & Population Approaches Not Mutually Exclusive You Can Do Both

  30. Social Ecology of Drinking What are some mutable factors that can shift the population distribution?

  31. Environmental Conditions Adult drinking Underage drinking

  32. Legal Availability Formal Social Controls Public Policy & Individual Risk Factors Drinking Alcohol-related Problems Institutional Behavior Policies/Structures Economic Availability Physical Adapted from Wagenaar & Perry, 1994 Availability Integrated theory of drinking behavior Problems that stem from alcohol use are primarily a function of availability

  33. Public Health Triad Host Agent Environment

  34. Knowledge Pricing Attitudes Composition Intentions Labeling Skills Packaging Advertising/Promotion Legal Sanctions Availability Institutions Physical Context SocioculturalContext KeyInfluencers Drug-Related Problems Person Drug Environment Torjman (1986)

  36. Assessing the State Alcohol Policy Environment in the United States

  37. 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

  38. Policy Environment Youth-SpecificPolicies • Youth Alcohol Pattern • 5+ (binge) drinking • Freq. 5+ drinking • Current drinking • Freq. current drinking • Drinking/Driving Adult-Oriented (i.e., population-based) Policies • Adult Alcohol Pattern • 5+ (binge) drinking • Freq. 5+ drinking • Heavy drinking • Total drinks • Current drinking
