Epidemiology of Alcohol Drinking and

All-Cause Mortality

► Individual studies suggest benefit of alcohol drinking on specific causes of death

► Meta-analysis of 34 large-scale studies (predominantly Europe and US) Di Castelnuovo, A. et al. Arch Intern Med 2006;166:2437-2445.

► Evidence of overall benefit with moderate drinking

► Rapid increase in morbidity and mortality with increase drinking

Page 8: 01-genest-acc-ll-200..

Alcohol Dosing and Total Mortality in

Men and in Women

► Studies (n=34); 1,015,835 subjects and 94,533 deaths.►Pooled data, adjusted for age, gender, social status, dietary factors, geographic origin►Adjustment for size of study, country, year of publication

What is a drink?

10 g Ethanol = 1 drink

►Wine (12.5% EtOH): 80 mL (!) one glass 125-200 mL

►Beer (5% EtOH): 200 mL (!) 1 bttle is 341 mL

►Scotch whisky (40% EtOH): 25 mL <1 ounce

So… ½ bottle of wine is 47 g Ethanol (roughly)

Geographic Differences?

►The available data does not allow to resolve the debate concerning the type of alcohol and health benefits

►Mediterranean style diet (wine with meals) differs markedly from beer drinkers or binge drinkers, more often encountered in the US

►Possibility of “healthy” ingredients in specific types of alcohol

►Value of social drinking on stress remains unexplored.

Resveratrol

Resveratrol is found in the skin of red grapes and is a constituent of red wine but, based on extrapolation from animal trials, apparently not in sufficient amounts to have a physiologically significant role in man.

Alcohol and Social Isolation

Andreev E, et al. Eur J Public Health. 2007 Dec 26• An investigation of the growing number of deaths of

unidentified people in Russia. “ unidentified men were at a higher risk of death from

exposure to natural cold, violence, alcoholic cardiomyopathy, acute respiratory infections and poisonings”

“The increase in deaths among unidentified men of working-age indicates the emergence of a health threat associated with homelessness and social marginalization.”

Page 49: 01-genest-acc-ll-200..

Conclusions

Alcohol intake has a small, but apparently beneficial effect on all-cause mortality (predominantly cardiovascular)

This benefit is partly offset by an increase in violent deaths, toxic cardiovascular effects and alcoholic liver disease

Page 50: 01-genest-acc-ll-200..

Recommendations

The drinking of fermented beverages is part of most cultures.

Prohibition attempts have failed to curb teenage drinking

Road-traffic accidents have decreased somewhat but still remain a major cause of death in teenage years and early adulthood

Moderate drinking appears to have no ill health effects

Page 51: 01-genest-acc-ll-200..

Recommendations

Avoid ACC Lake Louise
