Data Source
Data for this study were provided by participants in four cycles of NHANES: 1999-2000, 2001-2002, 2003-2004, and 2005-2006 (NHANES 1999-2006). NHANES is a continuing, cross-sectional, nationally representative survey of the US noninstitutionalized civilian population, conducted by the National Center for Health Statistics. It employs a complex, stratified, multistage probability sample design. In NHANES 1999-2006, a total of 41,474 individuals completed an in-person home interview, and 39,352
Characteristics
Because the NHANES is designed to provide estimates for the US population, the majority of the inferred population was non-Hispanic white (Table 1), had at least a high school education, did not currently smoke, and had a mean body mass index ≥25. In 1999-2006, 76% of men and 65% of women were current drinkers. Based on χ2 tests, unadjusted percentage distributions of all demographic and lifestyle characteristics differed significantly by drinking status (never, former, and current drinker) (P
Discussion
In this nationally representative study, diet quality was poorer among women who were current drinkers than among women who had never consumed alcoholic beverages. Among both men and women who were current drinkers, diet quality declined with increasing consumption of alcoholic beverages.
Although higher levels of alcoholic beverage consumption were associated with higher intakes of energy, protein, and some vitamins and minerals among current drinkers, they were also associated with lower diet
Conclusions
Regardless of drinking status, American adults' diet quality is relatively poor on average when compared to the recommendations of the 2005 DGA. During 1999-2006, the majority of Americans (76% of men and 65% of women) were current drinkers. This study found numerous associations between alcoholic beverage consumption and dietary intake. Increasing levels of alcoholic beverage consumption were associated with increasing intakes of some nutrients, but poorer diet quality, as indicated by
