Implementation Science Is Important for Understanding and Advancing Beverage Taxes

County- and state-level immigration policies are associated with Supplemental Nutrition Assistance Program (SNAP) participation among Latino households

The purpose of this study was to investigate the association between county- and state-level immigrant criminalizing and integrating policies and Latino household participation in the largest safety net program against food insecurity in the U.S., the Supplemental Nutrition Assistance Program (SNAP). Our outcome, county-level proportion of SNAP-participating Latino households, and county-level covariates were obtained from the American Community Survey 1-year county files (N = 675 counties) for 13 years (2007-2019). Our exposures were county-level presence of sanctuary policies and a state-level immigrant friendliness score, created based on 19 immigrant criminalizing and integrating state-level policies obtained from the Urban Institute's State Immigration Policies Resource. We classified every county in the sample as 1) sanctuary policy + immigrant friendly state, 2) sanctuary policy + immigrant unfriendly state, 3) no sanctuary policy + immigrant friendly state, and 4) no sanctuary policy + immigrant unfriendly state. Using multivariable generalized linear models that adjusted for poverty levels and other social composition characteristics of counties, we found that county-level SNAP participation among Latino households was 1.1 percentage-point higher in counties with sanctuary policies (B = 1.12, 95%CI = 0.26-1.98), compared to counties with no sanctuary policies, and 1.6 percentage-point higher in counties with sanctuary policies in immigrant friendly states (B = 1.59, 95%CI = 0.33-2.84), compared to counties with no sanctuary policy in immigrant unfriendly states. Local and state immigration policy, even when unrelated to SNAP eligibility, may influence SNAP participation among Latino households. Jurisdictions which lack sanctuary policies or have more criminalizing and less integrating policies should consider adopting targeted outreach strategies to increase SNAP enrollment among Latino households.

Embracing policy implementation science to ensure translation of evidence to cancer control policy

Although health-related policies are abundant, efforts to understand how to ensure that these policies serve as an effective vehicle for translating scientific evidence are relatively sparse. This paper explores how policy-focused implementation science (IS) may contribute to understanding the translation of scientific evidence to health-related policy in governmental and nongovernmental sectors. Expanding the focus of implementation science in cancer control could systematically address policy to both increase the use of scientific evidence in general and to address health equity. In this Commentary, we look to relevant work outside of IS that could be informative, most notably from the field of political science. We propose several ideas for future research that could help move the field of policy implementation science in cancer control in the USA forward. Although most efforts to increase uptake of the scientific evidence base reference translation to "practice and policy," there has been relatively little emphasis in the USA on implementation at the policy level, especially related to cancer control. If we are to achieve the full benefits of scientific discovery on population and public health, we will need to consider policy as a critical mechanism by which evidence can be translated to practice. We have a robust set of methods within implementation science that are increasing the pace of adoption and maintenance of evidence-based programs in a variety of settings. Building on these efforts, the time is right to expand our focus to include policy implementation.
