Correlations of serum lipids and lipoproteins with gamma-glutamyltransferase and attitude to alcohol consumption.

The correlation of three markers of alcohol consumption: serum concentration of gamma-glutamyltransferase (GT), high density lipoprotein cholesterol (HDL-cholesterol), apolipoprotein AI (Apo AI), and the results of a questionnaire (Mm-MAST) designed to measure the attitude towards alcohol consumption were determined in a population of healthy men aged 48 years. Apo AI (r = 0.27) and GT (r = 0.31) were correlated (P less than 0.001) to the questionnaire score to a similar degree while the correlation between HDL-cholesterol and the questionnaire score was (r = 0.18), somewhat less good but statistically significant (P less than 0.01). There was no correlation between GT and HDL-cholesterol or Apo AI.
