BACKGROUND: Risks and potential benefits associated with @entity167 use vary with the amount of @entity167 consumed on a drinking occasion. Over time, changes in the absolute and relative numbers of light or heavy @entity2749 may occur, impacting health and social problems. METHODS: Analyses of the 2000, 2005, and 2010 National @entity167 Surveys focus on trends in the volumes of @entity167 consumed on days where the drinker had 1 to 2, 3 to 4, or 5 or more drinks separately. These volume measures were obtained from graduated frequency questions with adjustments for estimated drink @entity167 content for each drinker based on reported beer brand, spirits drink and pour method, contexts of drinking, and demographic characteristics. Respondents with especially high @entity167 content drinks were adjusted up 1 category, and those with especially low @entity167 content drinks were adjusted down 1 category. Trend significance was tested with adjusted Wald tests and in negative binomial models with 2000 as the reference year, indicators for race/ethnicity group and interactions between these and survey year, and adjustments for age, educational attainment, income, employment status, and wetness region. Analyses were conducted both in the overall sample including abstainers and in the current drinker sample only. RESULTS: Overall trend results indicate an increase in drink @entity167 content-adjusted @entity167 volume of 25% from 2000 to 2010 with similar changes between 2000 to 2005 and 2005 to 2010. Most of the increase from 2000 to 2005 resulted from increased volume from light drinking (1 to 2 drinks) days for @entity1 and @entity1 and moderate to heavy drinking (3 to 4 drinks) days for @entity1 , while the change from 2005 to 2010 resulted mostly from volume from heavy drinking days (5+ drinks per day) for @entity1 . Black and Hispanic @entity1 were found not to have participated in the overall trend of increased @entity167 volume. CONCLUSIONS: Findings highlight shifts in drinking patterns suggesting increased heavy occasion drinking in 2010, particularly among @entity1 .
