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..](https://reader033.fdocuments.net/reader033/viewer/2022061218/54b7cbc84a7959104c8b49d9/html5/thumbnails/8.jpg)

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..](https://reader033.fdocuments.net/reader033/viewer/2022061218/54b7cbc84a7959104c8b49d9/html5/thumbnails/49.jpg)
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..](https://reader033.fdocuments.net/reader033/viewer/2022061218/54b7cbc84a7959104c8b49d9/html5/thumbnails/50.jpg)
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
