title: Association of a haemoglobin-acetaldehyde adduct with questionnaire results on heavy drinkers.
abstract: A new biological alcohol marker, the ratio between the acetaldehyde-induced haemoglobin fraction HbA1ach and the glycated haemoglobin fraction HbA1c (HbA1ach/HbA1c), was studied in association with data obtained in a questionnaire, the Malmö modified Michigan alcoholism screening test (Mm-MAST), completed by 270 consecutive middle-aged men participating in a voluntary health screening. None of them had earlier alcoholic health or alcohol-dependent social problems. The nine-question Mm-MAST correlated positively with the ratio of HbA1ach/HbA1c (r = 0.272, P less than 0.001). In the three drinker groups defined according to the questionnaire, HbA1ach/HbA1c values were significantly higher among heavy drinkers (mean = 40, S.E.M. = 1) than among teetotallers (mean = 32, S.E.M. = 2, P less than 0.01) or social drinkers (mean = 35, S.E.M. = 1, P less than 0.01). In the groups formed according to the respondents' own alcohol anamnesis there was no significant difference between the marker values, but the Mm-MAST score was significantly higher in both social (P less than 0.001) and heavy drinkers' (P less than 0.001) groups as compared with teetotallers. This shows that the questionnaire detected heavy drinkers better than the self-given anamnesis. The correlation of HbA1ach/HbA1c and the questionnaire means that the biological marker studied represents a new possibility to identify heavy drinkers before alcoholic health problems or social consequences have appeared.
