This paper reports the results of a study on alcohol drinking habits, alcohol-related acute symptoms, and alcohol abuse among Csángós, an ethnic minority in Hungary. The demographic data revealed their social characteristics: growing old, low education, endogamous marriages, early maternal age at birth of the first baby, and a high child number per family. Alcohol use survey revealed that alcohol consumption of the Csángós is considerably high; more than half of Csángó males and more than one-quarter of Csángó females are heavy drinkers. While all kinds of alcohol are consumed by males, wine drinking is more common among females. Acute reactions to a moderate dose of alcohol evoked a series of physical and physiological symptoms including facial flushing, higher pulse rate, tachycardia and euphoria among at least one third of the probands. There was a distinct gender difference in response to alcohol drinking. While a higher percentage of females reported intense skin flush (34%), a greater percentage of males reported symptoms such as sleepiness, euphoria and aggressiveness. The distribution of clinical chemical markers of alcohol abuse in the sera of the individuals under study confirmed heavier alcohol consumption among males than among females. Alcohol-related mortality data indicate liver cirrhosis and liver cancer as the leading cause of deaths among Csángó males. A high alcohol consumption among Csángó ethnic group reflects the acceptance of alcohol use in the community as an integral part of their lifestyle.
