Alcohol use disorders are well recognized to be common, debilitating, and the risk of developing them is influenced by family history (FH). The subjective response to alcohol may be determined familialy and related to the risk of developing alcoholism. The aim of this study was to evaluate differences between family history positive (FHP) and family history negative (FHN) individuals in their response to alcohol within the domains of subjective, coordination, and cognitive effects using an intravenous (IV) clamping method of alcohol administration.
Two groups of healthy subjects, those with an FHP (n = 65) versus those who were FHN (n = 115), between the ages of 21 to 30, participated in 3 test days. Subjects were scheduled to receive placebo, low-dose ethanol (EtOH) (target breath alcohol clamping [BrAC] = 40 mg%), and high-dose EtOH (target BrAC = 100 mg%) on 3 separate test days at least 3 days apart in a randomized order under double-blind conditions. Outcome measures included subjective effects, measures of coordination, and cognitive function.
Both low- and high-dose alcohol led to dose-related stimulant and sedative subjective effects as measured the Biphasic Alcohol Effects Scale and subjective measures of “high” and “drowsy” measured on a visual analog scale. However, there were no effects of FH. Similar dose-related effects were observed on cognitive and coordination-related outcomes, but were not moderated FH.
Results from this study showed that healthy individuals responded to an IV alcohol challenge in a dose-related manner; however, there were no significant differences on subjective response, or on EtOH-induced impairment of coordination or cognition, between individuals with a positive FH for alcoholism and those with a negative FH. Results suggest that FH may not be a specific enough marker of risk, particularly in individuals who are beyond the age where alcohol use disorders often develop.
