    Abstract:
    The associations among alcohol consumption, gamma-glutamyl transpeptidase (gamma-GTP) activity in serum and blood pressure (BP) were analysed in a cross-sectional study of 1,156 healthy male workers 35 to 59 years of age, consisting of 349 non-drinkers, 682 light-daily drinkers (consuming less than 58 ml of alcohol per day) and 125 heavy-daily drinkers consuming more. No marked elevation of BP with high alcohol consumption was seen in the present subjects. On the other hand, a linear elevation of BP together with an increase in serum gamma-GTP activity was found in subjects above 40 years of age. The BP levels corresponding to the three different drinking habits, non-drinkers, light drinkers and heavy drinkers, were similar to each other regarding gamma-GTP levels. The relationship between gamma-GTP and BP was shown, by multiple regression analysis, to be independent of age, obesity and the dose of alcohol consumed. The contribution to the rise in BP of the dose of alcohol consumed, in comparison with that of gamma-GTP, was negligible. Serum gamma-GTP activity is a useful indicator of the susceptibility to the pressor effect of alcohol.
