Popis: Background Nutrition interventions promoting healthy food choices aim to address health challenges of residents in low-income environments. Research about the effectiveness of nutrition interventions in low-income populations is limited, particularly for those in rural areas. Behavioral economics (BE) strategies demonstrate effectiveness for improving eating behaviors in some settings. However, the efficacy of BE interventions in retail food stores serving low-income populations residing in rural and urban geographies is nascent. Objective This systematic literature review aims to identify and compare nutrition interventions implemented in rural and urban low-income retail food stores, including BE strategies when applied. Methods This review was conducted according to Preferred Reporting Items for Systematic Reviews and Meta-Analyses guidelines. Reviewers searched five databases for peer-reviewed publications from October 2010 to October 2019. Included studies implemented a nutrition intervention in low-income retail food stores and provided a quantitative outcome evaluation with results separated by rural and urban geography. BE interventions were analyzed based on the MINDSPACE framework for behavior change. Results Forty-six separate publications (n = 20 rural, n = 26 urban) in the United States, Canada, Europe, New Zealand, and Australia were included. Researchers independently rated publications as low risk of bias (n = 4), moderate (n = 18), or high risk of bias (n = 24) using the Quality Assessment Tool for Quantitative Studies. Studies (n = 18) demonstrated positive outcomes for customer purchases, store sales, or participant intake of targeted healthy foods. Overall, most effective interventions included point-of-purchase signage (n = 16) and product placement strategies (n = 4 urban). Rural studies included financial incentives combined with participant education (n = 2) and incorporated culturally appropriate messengers and/or symbols (n = 5) to improve healthy food purchases and intake. Conclusions Improved research quality and tailored evidence-based interventions, including BE strategies, are necessary in retail food environments to promote healthy eating behaviors in low-income populations.
