AIMS: To evaluate the clinical course of specific alcohol-related life problems and the risk for dependence on illicit drugs in individuals with relatively low and high levels of response (LR) to alcohol earlier in life.
SUBJECTS: From among 439 men who were part of the 15-year follow-up of sons of alcoholics and controls, 108 were identified as having fulfilled criteria for DSM-III-R alcohol dependence.
MEASURES: The LR to alcohol was originally evaluated following the consumption of 0.61 g/kg of ethanol at age 20 by determining the levels of change in subjective feelings of intoxication, body sway and several hormones such as cortisol. From the 453 original subjects, 450 completed a face-to-face 10-year follow-up evaluation, and 439 completed the 15-year protocol.
FINDINGS: A comparison of the clinical course of 50 alcohol-dependent men with clearly low LR values at age 20 with that for 42 individuals whose LR scores were above the median revealed few differences. Those with a low LR had a slightly earlier age of onset of alcohol dependence (24.8 +/- 3.41 vs. 26.6 +/- 4.48 years), and this finding was unrelated to the presence of an alcohol-dependent father. Otherwise the members of the two groups demonstrated a similar course of alcohol dependence. There was no relationship between a low LR at age 20 and either the pattern of substances used or the rate of dependence on illicit drugs.
CONCLUSIONS: The results indicate that for this sample a low LR to alcohol, while associated with a high risk for alcohol dependence, was not related to most aspects of the course of alcohol problems once dependence developed.
