Popis: OBJECTIVE: Self-reported alcohol consumption in U.S. public health surveys covers only 30%–60% of per capita alcohol sales, based on tax and shipment data. To estimate alcohol-attributable harms using alcohol-attributable fractions, accurate measures of total population consumption and the distribution of this drinking are needed. This study compared methodological approaches of adjusting self-reported survey data on alcohol consumption to better reflect sales and assessed the impact of these adjustments on the distribution of average daily consumption (ADC) levels and the number of alcohol-attributable deaths. METHOD: Prevalence estimates of ADC levels (i.e., low, medium, and high) among U.S. adults who responded to the 2011–2015 Behavioral Risk Factor Surveillance System (BRFSS; N = 2,198,089) were estimated using six methods. BRFSS ADC estimates were adjusted using the National Alcohol Survey, per capita alcohol sales data (from the Alcohol Epidemiologic Data System), or both. Prevalence estimates for the six methods were used to estimate average annual alcohol-attributable deaths, using a population-attributable fraction approach. RESULTS: Self-reported ADC in the BRFSS accounted for 31.3% coverage of per capita alcohol sales without adjustments, 36.1% using indexed-BRFSS data, and 44.3% with National Alcohol Survey adjustments. Per capita sales adjustments decreased low ADC prevalence estimates and increased medium and high ADC prevalence estimates. Estimated alcohol-attributable deaths ranged from approximately 91,200 per year (BRFSS unadjusted; Method 1) to 125,200 per year (100% of per capita sales adjustment; Method 6). CONCLUSIONS: Adjusting ADC to reflect total U.S. alcohol consumption (e.g., adjusting to 73% of per capita sales) has implications for assessing the impact of excessive drinking on health outcomes, including alcohol-attributable death estimates.
