title: Comparison of gamma-glutamyltransferase and other health screening tests in average middle-aged males, heavy drinkers and alcohol non-users.
abstract: Physical and biochemical health screening variables were compared in matched, middle-aged male samples of (a) ideological teetotallers, (b) average men, (c) self-reported alcohol abstainers, (d) low gamma-glutamyltransferase (GGT) activity, and (e-f) high GGT activity with or without admitted alcohol consumption background. The alcohol non-user groups and the individuals with low GGT had significantly lower mean values of relative body weight, pulse, systolic and diastolic blood pressure, haematocrit, serum urate, triglyceride, cholesterol, and zero and 120 min blood glucose than individuals with elevated GGT and alcohol overconsumption. The average men had intermediate levels. The frequency of increased values of the same tests was notably higher in the subjects with elevated GGT and heavy alcohol consumption than in the teetotallers and the other groups; and was lowest in the teetotallers.
