ABSTRACT
Background: Light to moderate alcohol intake lowers therisk of cardiovascular mortality, but whether thisprotective effect can be attributed to a specific type ofbeverage remains unclear. Moreover, little is known aboutthe effects of long-term alcohol intake on life expectancy.
Methods: The impact of long-term alcohol intake and types of alcoholic beverages consumed on cardiovascular mortality and life expectancy at age 50 was investigated in the Zutphen Study, a cohort of 1373 men born between 1900and 1920 and examined repeatedly between 1960 and2000. Hazard ratios (HRs) for total alcohol intake and alcohol from wine, beer and spirits were obtained from time dependent Cox regression models. Life expectancy at age 50was calculated from areas under survival curves.
Results: Long-term light alcohol intake, that is (20 g per day, compared with no alcohol, was strongly and inversely associated with cerebrovascular (HR 0.43, 95%CI 0.26 to 0.70), total cardiovascular (HR 0.70, 95% CI0.55 to 0.89) and all-cause mortality (HR 0.75, 95% CI0.63 to 0.91). Independent of total alcohol intake, long term wine consumption of, on average, less than half a glass per day was strongly and inversely associated with coronary heart disease (HR 0.61, 95% CI 0.41 to 0.89),total cardiovascular (HR 0.68, 95% CI 0.53 to 0.86) and all-cause mortality (HR 0.73, 95% CI 0.62 to 0.87). These results could not be explained by differences in socioeconomic status. Life expectancy was about 5 years longer in men who consumed wine compared with those who did not use alcoholic beverages.
Conclusion: Long-term light alcohol intake lowered cardiovascular and all-cause mortality risk and increased life expectancy. Light wine consumption was associated with 5 years longer life expectancy; however, more studies are needed to verify this result.

The impact also depends on the exact amount drunk -- more than half a glass starts bringing life expectancy down again, according to researchers from Wageningen University in the Netherlands.
"Drinking wine was strongly associated with a lower risk of dying from coronary heart disease, cerebrovascular disease, and death from all causes," said the study.
Effects varied, however: men who drink up to 20 grammes of any type of alcohol per day live for about two years longer than non-drinkers, while the length of time is slightly lesser for those drinking more than 20 grammes.
Those drinking only wine, and less than half a glass a day, lived some 2.5 years longer than those who drank beer and spirits, and almost five years longer than non-drinkers, said the study.
The study, published in the Journal of Epidemiology and Community Health, was based on research on some 1,373 men between 1960 and 2000. It did not draw conclusions for women.
The researchers studied how much alcohol they drank and what type, in an attempt to assess the impact of their drinking habits on cardiovascular disease, cerebrovascular disease, and from all causes.
They also tracked weight and diet and whether the men smoked.
The results held true regardless of socio-economic status, diet or lifestyle, it found.
