The use of standard drink units (SDUs) in the measurement of individual
alcohol consumption has become widely popular in recent year. However, the
ethanol content of drinks varies from country to country and is usually
arrived at without scientific backing. The present study was designed to
establish an SDU for a predominantly wine-drinking country (Spain). Two
field studies were simultaneously conducted to gather data about home and
public alcohol consumption in eight regions of the country with a total of
10 751 subjects. The average alcohol content of a drink was very similar
for wine and beer, whereas in the case of spirits it was almost double.
Relevant differences were found across regions, drinking settings and city
sizes. A Spanish SDU was set at 10 g of ethanol for wine and beer, with a
measure of spirits accounting for two SDUs. The use of SDUs should be
encouraged in primary health care settings. However, dispersion of data
suggests that, when SDU is used as a screening tool, additional information
should always be obtained in borderline cases.
