Alcohol policy effects on 100% chronic alcohol-attributable mortality across racial/ethnic subgroups

In the United States, some racial/ethnic minorities suffer from higher rates of chronic alcohol problems, and alcohol-related morbidity and mortality than Whites. Furthermore, state-level alcohol policies may affect racial/ethnic subgroups differentially. We investigate effects of beverage-specific taxes and government control of spirits retail on alcohol-related mortality among non-Hispanic Whites, non-Hispanic Blacks, non-Hispanic American Indians/Alaska Natives (AI/AN) and Hispanics using death certificate and state-level alcohol policy data for 1999-2016. Outcomes were analyzed as mortality rates (per 10,000) from 100% alcohol-attributable chronic conditions ("100% chronic AAD"). Statistical models regressed racial/ethnic-specific logged mortality rates on state-level, one-year lagged and logged beer tax, one-year lagged and logged spirits tax, and one-year lagged government-controlled spirits sales, adjusted for mortality trends, fixed effects for state, and clustering of standard errors. Government control was significantly (P < 0.05) related to 3% reductions in Overall and non-Hispanic White mortality rates, and 4% reductions in Hispanic mortality rates from 100% chronic AAD. Tax associations were not robust. Results support that government control of spirits retail is associated with significantly lower 100% AAD from chronic causes Overall and among non-Hispanic Whites and Hispanics. Government control of spirits retail may reduce both population-level 100% chronic AAD as well as racial/ethnic disparities in 100% chronic AAD.
