Project Title: Sipsmarter Southwest Virginia: a Systems-Based Approach to Disseminate Andimplement an Effective Sugar-Sweetened Beverage Reduction Intervention
Fiscal Year: 2017


 DESCRIPTION (provided by applicant): The slow translation of health-related research findings into practice is well documented and this extends to health literacy interventions. Our R21 application is driven by the desire to reduce the excessive lag time along the research pipeline by speeding the translation of emergent findings from SIPsmartER, a health literacy intervention to reduce sugar-sweetened beverage (SSB) consumption. SSB consumption is a high priority public health behavior and contributes ~7% of total energy intake for US adults. Unfortunately, the targeted Appalachian region of Southwest Virginia for this application exceeds the national average consumption of SSB by more than three times. SIPsmartER is a theory-based, 6-month, multi-component health literacy intervention designed to reduce SSB intake and is currently being tested in a type 1 effectiveness- implementation hybrid randomized-controlled trial. Emerging findings from this rigorously designed trial illustrate that SIPsmartER is an efficacious intervention to decrease SSB intake: intervention participants have significantly decreased SSB intake by 227 SSB kcals/day (95% CI=326, 127; p<0.001) from 0 to 6 months compared to a decrease of 53 SSB kcals/day (95% CI=326, 127; p<0.001) in the control group (p<0.001). Furthermore, SSB outcomes and SIPsmartER completion rates do not vary by health literacy status and preliminary data indicate that SSB reductions are being sustained one year post intervention. To translate these promising effects into population-level SSB reductions, a concerted effort is needed to understand the feasibility of organizational-level adoption and implementation of SIPsmartER within existing systems and to develop an implementation support system to aid in delivery. Additionally, since a system-delivered SIPsmartER intervention would be conducted under less-controlled conditions, ascertaining individual-level effects on SSB is necessary. Thus, our approach is guided by the RE-AIM (Reach, Effectiveness, Adoption, Implementation, and Maintenance) Framework and integrates the Interactive Systems Framework and cutting- edge strategies for advancing organizational-level health literacy. We target four medically-underserved Southwest Virginia Department of Health districts and their client population, and propose a mixed-methods design that includes formative, process, and outcome evaluations. Our primary aim is to develop, establish feasibility, and determine the potential utility of an implementation strategy for SIPsmartER, which will reflect system-level needs and resources specific to SIPsmartER, as well as build general capacity related to organizational health literacy. Secondary aims are to determine the adoption and implementation process at the organization-level and determine individual-level reach and effectiveness of SIPsmartER within an existing system. The goal is to have a SIPsmartER implementation support system that can be tested in a subsequent R01 type 3 effectiveness-implementation hybrid randomized-controlled trial, with a long-term goal of broad scale SIPsmartER dissemination within public health systems to achieve population-level SSB reductions.
