Potential Conflict of Interest Partial expenses for operating the Forum are from unrestricted donations to Boston University from associations and companies in the beverage industry (including NY Wine & Grape Foundation, Diageo, Brown-Forman) As donors have no input into the papers reviewed by the Forum or the opinions published, the IRB at Boston University has deemed that these do not constitute a conflict of interest.

“Should We Recommend Alcohol for its Health Benefits?” Among the factors that we must consider: 1.Is excessive alcohol intake associated with adverse health effects? 2.Is light-to-moderate alcohol intake associated with beneficial health effects? Is it the cause? 3.Does the pattern of drinking affect the net health effects? (speed of intake, with food, regular vs binge) 4.Does the type of beverage affect the net health effects? 5.Is the public often faced with biased, exaggerated statements about alcohol? What are proper guidelines?

Types of Scientific Evidence Case reports Ecologic data (comparing populations without individual data) Case-control studies Prospective cohort studies (may be population-based, must deal with confounders) Experimental data Human clinical trials (for intermediary outcomes, for disease outcomes)

Potential Confounding in Observational Studies There is often clustering of healthy lifestyle factors We must deal with such potentially confounding variables: Age Sex Cigarette smoking Education, occupation, and income Diet, physical activity, level of obesity Previous alcohol use Adjust for many of these factors through stratification and multivariable analysis techniques.

Research on Alcohol and Cardiovascular Disease Prospective epidemiologic studies for many decades, even when fully controlled for known confounding, have been amazingly consistent: moderate drinkers are at lower risk of CHD than are abstainers.

Alcohol & CHD: Meta-analysis Corrao et al, 2000

Alcohol Consumption and CHD Mortality: Review & Meta-analysis. Ronksley et al. BMJ 2011 Reviewed 84 well-done prospective epidemiologic studies; > 1 million subjects. Estimated effects of alcohol intake on mortality from coronary heart disease

Effects of Alcohol on Cardiovascular Disease (Ronksley et al, 2011) ■ This meta-analysis showed ■ This meta-analysis showed risk reductions for moderate alcohol drinkers of 25% for CHD mortality 29% for incident coronary heart disease 25% for cardiovascular disease mortality 13 % for all-cause mortality.

Alcohol & Mortality, adjusting for SES and a Propensity Score (Lee et al, 2009) 12,519 subjects, Health & Retirement Study With demographic adjustments, moderate drinkers ( ≤ 1 drink/day vs non-drinkers) had a RR for mortality of 0.50. With full adjustments for SES, RF, behavioral factors and a propensity score for moderate drinking, RR was 0.62 (CI 0.48-0.80).

Net Effect of Moderate Alcohol Intake on Mortality (Konnopka et al, 2009) Considered "moderate" up to 40 grams/day (more than 3 drinks/day) for men and up to 20 g/day (about 1 1/2 drinks/day) for women; included binge drinkers. Deaths "avoided" by moderate alcohol use were about twice as high (n=29,818) as the number "caused" by moderate drinking (n=14,457)

Deaths Attributable to “Moderate” Alcohol Intake (weekly mean <40 g/d for men, < 20 g/day for women) Deaths Attributable to “Moderate” Alcohol Intake (weekly mean <40 g/d for men, < 20 g/day for women) (Rehm et al, Ann Epidem, 2007)

We can apply similar approaches in giving population advice, as well. He added that most people know very well what the difference is between light to moderate drinking and binge or excessive drinking. While some patients may rationalize their heavy drinking because of its purported health effects, he has yet to find someone who had developed alcohol abuse because of messages about the health effects of moderate drinking. Medical practitioners, in his view, have a ‘‘solemn duty’’ to tell the truth about alcohol consumption, as they understand it, to all of their patients.

The Ultimate Clinical Trial on Alcohol & Health Recruit Recruit 50,000 normal, healthy 60 year-old people who are occasional drinkers with no previous hx of misuse & not confirmed abstainers Evaluate them in a run-in period, with incentives to remain for 20-25 years Provide them with a blinded beverage (either containing alcohol or no alcohol) Assure that they drink a certain amount (perhaps 12 grams/alcohol) every evening, avoiding all other alcoholic beverages (except perhaps for religious services, weddings, and funerals) Closely monitor compliance (blood tests, bottle counts, etc.) ; use intensive incentives to assure continued participation Arrange follow up for 20-25 years to see which group ages better and lives longer (Unlike pharmaceutical trials, must not fund this study with grants from interested parties)

Diet and obesity were the next most common; alcohol was attributed in 4% of cases.

The authors do not add that for moderate drinking, the net effect is a reduction in total mortality, or greater survival.

Total Mortality, by Alcohol Consumption Di Castelnuovo et al, 2006

Does Heavy Drinking by Adults Respond to Higher Alcohol Prices and Taxes? A Survey and Assessment (JP Nelson, Dept of Economics, Pennsylvania State Univ, 2013) Higher alcohol prices and taxes are frequently proposed as a policy tool to deal with abusive consumption A review of 19 individual-based studies that examine price responses by heavy-drinking adults finds only 2 studies with a significant negative price response among heavy drinkers. Many studies show that moderate-drinking adults have significant and substantial price/tax elasticities Many studies show that moderate-drinking adults have significant and substantial price/tax elasticities

The Impact of a Large Reduction in Alcohol Prices in Finland on Mortality Herttua et al, Int J Epidemiol, 2010 Markedly lowering the price of alcohol in Finland increased the number of alcohol-related deaths by 14-40% = 0 to 2.9 excess deaths each month, by age group Lowering the price decreased by up to 24% the number of deaths from cardiovascular disease = 0 to 24.8 excess deaths each month, by age group For all-cause mortality, 42 to 69 fewer monthly deaths

The Moral Bases for Public Health Interventions. (Cole P, Epidemiology 1995;6:78–83) (Cole P, Epidemiology 1995;6:78–83) “Policy should be based not on paternalism (‘We professionals know what is best’) but on education and the assumption that ‘informed people make healthful choices.” Cole adds, ‘‘Health education should be education and not propaganda; it becomes the latter when only one side of an issue is presented to the public.’’

Lionel Tiger on Alcohol Guidelines “We have seen the rise of what he calls ‘concernocrats,’ people who are motivated by well-meaning concern for the welfare of others and are prepared, therefore, to exert their power over the behavior and disposition of others. ‘‘It is a very tempting thing for well-meaning people to make statements about other people’s health and welfare because the population is primed for quasi-religious advice from the druids, the priests who advise us.”

Lionel Tiger on Alcohol Guidelines “Those of us in the comment business need to be extremely careful about what we say, not because people may drink too much, or too little, but because we may nominate ourselves as ‘gurus’ of everyone’s destiny and inspect their behaviors too carefully.”

Alcohol and Obesity 2011-2013 Sayon-Orea et al reviewed publications on alcohol and obesity. They concluded: “It is Sayon-Orea et al reviewed publications on alcohol and obesity. They concluded: “It is possible that heavy drinkers may increase their risk of obesity. “Light-to-moderate alcohol intake, especially wine intake, may be more likely to protect against weight gain, whereas consumption of spirits has been positively associated with weight gain.”

Alcohol & Cardiovascular Disease Ecologic studies, such as those describing the “French Paradox,” compare populations in the aggregate, but do not contain individual data. May generate hypotheses, not test them. For the latter, clinical trials are best; but we often have to rely on prospective epidemiologic studies that are adequately adjusted for confounders.

Sin Taxes: Do Heterogenous Responses Undercut Their Value? Ayyagari et al, National Burerau of Econommic Research, 2009 “Only a subgroup responds significantly to price. Importantly, the unresponsive group drinks more heavily, suggesting that a higher price could fail to curb drinking by those most likely to cause negative externalities. “In contrast, those least likely to impose costs on others are more responsive, thus suffering greater deadweight loss yet with less prevention of negative externalities.”
