Alcohol and mortality in the Italian rural cohorts of the Seven Countries Study. International Journal of Epidemiology 1992; 21: 74–82. The relation of alcohol consumption to mortality is examined using the data of the Italian rural cohorts of the Seven Countries Study, a prospective investigation of factors related to cardiovascular disease (CVD). The present analysis includes 1536 men aged 45–64, whose dietary habits and food consumption, including alcoholic beverages, were measured in 1965. Of them, 463 men died in a follow-up period of 15 years. The analysis shows a J-shaped relationship between alcohol consumption, expressed as percentage of total daily energy intake, and both overall mortality and cardiovascular mortality; this J-shaped relationship is evident even after adjusting for age, cigarette smoking and occupation. The inverse relationship for consumption of small quantities of alcohol, which is represented by the left side of the J-curve, is no longer significant when all men with previous cardiovascular manifestations are excluded from the analysis, yet it is never completely eliminated.
