BACKGROUND Empirically based estimates of the mean alcohol content of beer, wine and spirits drinks from a national sample of US drinkers are not currently available. METHODS A sample of 310 drinkers from the 2000 National Alcohol Survey were re-contacted to participate in a telephone survey with specific questions about the drinks they consume. Subjects(More)
Lifetime abstainers have often been recommended as the comparison group in alcohol epidemiology. The objective of this study was to provide insight into the validity and stability of lifetime abstention by using data derived from the National Alcohol Survey, a national probability survey of US households conducted in 1984, and its 2 follow-up surveys(More)
OBJECTIVE Evidence suggests that people misjudge the size of their drinks, calling into question the validity of data from surveys and screening instruments assessing alcohol quantity in terms of standard drinks. This article studied the validity of photographs of glasses to assess drink size. METHOD In a U.S. national sample of 323 drinkers, respondents(More)
OBJECTIVE To assess the stability of individual monthly alcohol consumption volume in three studies from the United States: The first National Health and Nutrition Examination Survey with three measurements, The Framingham Offspring and Spouse Cohort with four measurements, and the National Longitudinal Survey of Youth with six measurements. The results(More)
BACKGROUND While prior studies have reported racial/ethnic disparities in alcohol-related problems at a given level of heavy drinking (HD), particularly lower levels, it is unclear whether these occur in both genders and are an artifact of racial/ethnic differences in drink alcohol content. Such information is important to understanding disparities and(More)
This paper examines how estimates of the price elasticity of demand for beer vary with the choice of alcohol price series examined. Our most important finding is that the commonly used ACCRA price data are unlikely to reliably indicate alcohol demand elasticities-estimates obtained from this source vary drastically and unpredictably. As an alternative,(More)
Data are from the 2000 National Alcohol Survey Methodological Follow-up, which includes 323 individuals from across the United States. Directly measured estimates of drink volume and amount left unfinished along with self-report of the frequency and reasons for which drinks are not finished and are compared across groups. Overall, 12% of drinks reported in(More)
We obtain the nucleation rate of critical droplets for an elastic string moving in a double-well potential and subject to noise and damping forces. We obtain this rate for a class of potentials that includes both the asymmetric straight phi(4) and the straight phi(6) potentials. The frequencies of small oscillations about the critical droplet are obtained(More)
BACKGROUND Prior studies adjusting self-reported measures of alcohol intake for drink size and ethanol (EtOH) content have relied on single-point assessments. METHODS A prospective 28-day diary study investigated magnitudes of drink-EtOH adjustments and factors associated with these adjustments. Transdermal alcohol sensor (TAS) readings and prediction of(More)
We obtain the nucleation rate of critical droplets for an elastic string moving in a phi(6) local potential and subject to noise and damping forces. The critical droplet is a bound soliton-antisoliton pair that carries a section of the string out of the metastable central minimum into one of the stable side minima. The frequencies of small oscillations(More)
