Abstract
Summary: The subjects were recruited from participants in a health examination of random samples of the adult population in Stockholm county. Those aged 18–64years who admitted a high alcohol consumption (>40 g 100% ethanol/day) among men and <30 g among women) or had an elevated value of serum‐gammaglutamyltransferase (GOT) (cut‐off point 1.0 microkatal/l for men and 0.6 microkatal/l for women) or had certain other indications of a high alcohol consumption were included. More severe cases, and those with an elevated GOT due to reasons other than alcohol, were excluded. The remaining subjects, 70 men and 13 women, were allocated at random to either an intervention or a comparison group. An elevated GGT was the main inclusion criteria. The subjects in the comparison group were advised by the general practitioner to cut their alcohol consumption, while those in the intervention group made further visits to their general practitioner, who gave general support and used an elevated GGT as an indication of the recent level of alcohol consumption at consecutive visits. There were three visits on average, so we are comparing a group receiving advice with a group receiving further minimal intervention. At the one‐year follow‐up there were greater, however not significant, reductions in GGT‐level, in self‐reported alcohol consumption and in a ‘problem index’ in the minimal intervention group than in the comparison group.
