Data were weighted to adjust for the probability of selection (number of households, multiple phone lines and adult residents in households) and nonresponse. Post-stratification weights were also applied to reflect the U.S. Census-derived demographics of the U.S. population ages 18 and older (gender, age, race/ethnicity and region, and among Hispanics, U.S. nativity). The Hispanic oversample was further adjusted to reflect the income distribution of the main sample. With the exception of factor analyses to derive the composite heavy drinking measure, all analyses were weighted and conducted using Stata survey commands (Stata Corp., 2005) that apply appropriate standard errors adjusting for probabilities of selection and post-stratification weighting. T-tests and chi-square analyses were used to compare indicators of heavy drinking, alcohol-related problems and social disadvantage among African Americans and Hispanics in relation to whites.
