Objective No studies have examined whether alcohol taxes may be relevant for reducing harms related to pregnant people's drinking. Method We examined how beverage-specific ad valorem , volume-based, and sales taxes are associated with outcomes across three data sets. Drinking outcomes came from women of reproductive age in the 1990–2020 US National Alcohol Surveys (N  = 11 659 women |$\le$| 44 years); treatment admissions data came from the 1992–2019 Treatment Episode Data Set: Admissions (N  = 1331 state-years; 582 436 pregnant women admitted to treatment); and infant and maternal outcomes came from the 2005–19 Merative Marketscan® database (1 432 979 birthing person–infant dyads). Adjusted analyses for all data sets included year fixed effects, state-year unemployment and poverty, and accounted for clustering by state. Results Models yield no robust significant associations between taxes and drinking. Increased spirits ad valorem taxes were robustly associated with lower rates of treatment admissions [adjusted IRR = 0.95, 95% CI: 0.91, 0.99]. Increased wine and spirits volume-based taxes were both robustly associated with lower odds of infant morbidities [wine aOR = 0.98, 95% CI: 0.96, 0.99; spirits aOR = 0.99, 95% CI: 0.98, 1.00] and lower odds of severe maternal morbidities [wine aOR = 0.91, 95% CI: 0.86, 0.97; spirits aOR = 0.95, 95% CI: 0.92, 0.97]. Having an off-premise spirits sales tax was also robustly related to lower odds of severe maternal morbidities [aOR = 0.78, 95% CI: 0.64, 0.96]. Conclusions Results show protective associations between increased wine and spirits volume-based and sales taxes with infant and maternal morbidities. Policies that index tax rates to inflation might yield more public health benefits, including for pregnant people and infants. [ABSTRACT FROM AUTHOR]

Aims We examined relationships between pregnancy-specific alcohol policies and admissions to substance use disorder treatment for pregnant people in the USA. Methods We merged state-level policy and treatment admissions data for 1992–2019. We aggregated data by state-year to examine effects of nine pregnancy-specific alcohol policies on the number of admissions of pregnant women where alcohol was reported as the primary, secondary, or tertiary substance related to the treatment episode (N  = 1331). We fit Poisson models that included all policy variables, state-level controls, fixed effects for state and year, state-specific time trends, and an offset variable of the number of pregnancies in the state-year to account for differences in population size and fertility. Results When alcohol was reported as the primary substance, civil commitment [incidence rate ratio (IRR) 1.45, 95% CI: 1.10–1.89] and reporting requirements for assessment and treatment purposes [IRR 1.36, 95% CI: 1.04–1.77] were associated with greater treatment admissions. Findings for alcohol as primary, secondary, or tertiary substance were similar for civil commitment [IRR 1.31, 95% CI: 1.08–1.59] and reporting requirements for assessment and treatment purposes [IRR 1.21, 95% CI: 1.00–1.47], although mandatory warning signs [IRR 0.84, 95% CI: 0.72–0.98] and priority treatment for pregnant women [IRR 0.88, 95% CI: 0.78–0.99] were associated with fewer treatment admissions. Priority treatment findings were not robust in sensitivity analyses. No other policies were associated with treatment admissions. Conclusions Pregnancy-specific alcohol policies related to greater treatment admissions tend to mandate treatment rather than make voluntary treatment more accessible, raising questions of ethics and effectiveness.
