Alcohol-related flushing and the risk for alcoholism in sons of alcoholics.
Ethanol-induced facial flushing was measured in 30 men, aged 21 to 25, who had family histories of alcoholism and in 30 matched controls. The drug was administered as 0.75 ml of 95% ethanol per kilogram of body weight, mixed with a sugar-free soft drink and consumed over 5 minutes. Facial flushing was assessed over 90 minutes using both observational ratings and a plethysmograph. Family history positive (FHP) subjects demonstrated significantly higher levels of flushing than family history negative (FHN) controls on objective measures. Correlations with the flushing response were .83 for blood acetaldehyde, and at least .60 for heart rate and skin temperature. This is the first known demonstration in Caucasians of a possible association between flushing and blood acetaldehyde levels in individuals hypothesized to be at risk for the development of alcoholism.
