Existing studies addressing alcohol consumption have not captured the multidimensionality of drinking patterns, including drinking frequency, binge drinking, beverage preference and changes in these measures across the adult life course. The authors of a paper, published in the British Journal of Nutrition, examined longitudinal trends in drinking patterns and their association with diet over four decades in 4,956 ageing US adults from the Framingham Offspring Study. Alcohol intake (drinks/week, drinking frequency, beverage-specific consumption, drinks/occasion) was assessed every 4 years from examinations 1 to 8. Participants were classified as binge drinkers, moderate drinkers or heavy drinkers (4+ and 5+ drinks/occasion; ≤1 and ≤2 drinks/d and >7 and >14 drinks/week for women and men, respectively). Dietary data were collected by a food frequency questionnaire from examinations 5 to 8 (1991-2008). The study authors evaluated trends in drinking patterns using linear mixed effect models and compared dietary intake across drinking patterns. Alcohol consumption decreased from 1971 to 2008 (3·7 v. 2·2 oz/week). The proportion of moderate (66 v. 59·3 %), heavy (18·4 v. 10·5 %) and binge drinkers (40·0 v. 12·3 %) declined. While average wine consumption increased (1·4 v. 2·2 drinks/week), beer (3·4 v. 1·5 drinks/week) and cocktail intake (2·8 v. 1·2 drinks/week) decreased. Non-binge drinkers consumed less sugary drinks and more whole grains than binge drinkers, and the latter consumed more total fat across all examinations. There was a significant difference in consumption trends of total grains by drinking level. In conclusion, alcohol drinking patterns are unstable throughout adulthood. Higher intakes were generally associated with poorer diets. These analyses support the nuanced characterisation of alcohol consumption in epidemiological studies.
