The amount of alcohol consumed during a given drinking occasion is strongly associated with the duration of the occasion combined with the beverage type and serving size, according to a study reported in Alcoholism: Clinical and Experimental Research. Although previous research had indicated that alcohol consumption is influenced by the drinking context — for example, by the location, timing, or who was in the drinking group — it was not clear which characteristics are most strongly associated with alcohol consumption and how different factors combine to affect it. The new study aimed to identify which features, and combinations of features, are most predictive of the units of alcohol consumed during drinking occasions in Great Britain.
