Preventing Chronic Disease (PCD) is a peer-reviewed electronic journal established by the National Center for Chronic Disease Prevention and Health Promotion. PCD provides an open exchange of information and knowledge among researchers, practitioners, policy makers, and others who strive to improve the health of the public through chronic disease prevention.

Food insecurity in rural settings is complex and not fully understood, especially from the perspective of low-income and Black residents. The goal of this study was to use qualitative methods to better understand experiences with food access and perceptions of the food environment among low-income, predominately Black rural Louisiana residents in the United States. Data were collected from focus group discussions (FGD) and focus group intake forms. Study participants were all rural residents eligible to receive at least one nutrition assistance program. FGD questions focused on perceptions of the food environment, with an emphasis on food access. Participants (n = 44) were predominately Black and female. Over half (n = 25) reported running out of food before the end of the month. Major themes included: store choice, outshopping, methods of acquiring foods other than the grocery store, and food insecurity. Concerns around price, quality, and transportation emerged as factors negatively impacting food security. Understanding residents’ perceptions and experiences is necessary to inform contextually appropriate and feasible policy and practice interventions that address the physical environment and social conditions that shape the broader physical food environment in order to achieve equitable food access and food security.

Summary: Sugar‐sweetened beverages (SSBs) are a primary source of added sugars in the American diet. Habitual SSB consumption is associated with obesity and noncommunicable disease and is one factor contributing to U.S. health disparities. Public health responses to address marketing‐mix and choice‐architecture (MMCA) strategies used to sell SSB products may be required. Thus, our goal was to identify original research about stocking and marketing practices used to sell SSB in U.S. food stores. We used Preferred Reporting Items for Systematic Reviews and Meta‐Analyses (PRISMA) and the World Health Organization (WHO) protocol for rapid reviewing. We searched six databases and Google Scholar using key terms focused on store type and SSB products. We characterized results using an MMCA framework with categories place, profile, portion, pricing, promotion, priming or prompting, and proximity. Our search resulted in the identification of 29 articles. Most results focused on profile (e.g., SSB availability) (n = 13), pricing (e.g., SSB prices or discounts) (n = 13), or promotion (e.g., SSB advertisements) (n = 13) strategies. We found some evidence of targeted MMCA practices toward at‐risk consumers and differences by store format, such as increased SSB prominence among supermarkets. The potential for systematic variations in MMCA strategies used to sell SSB requires more research. We discuss implications for public health, health equity, and environmental sustainability.

African Americans experience high rates of obesity and food insecurity in part due to structural racism, or overlapping discriminatory systems and practices in housing, education, employment, health care and other settings. Nutrition education and nutrition-focused policy, systems and environmental changes may be able to address structural racism in the food environment. This scoping review aimed to summarise the available literature regarding nutrition interventions for African Americans that address structural racism in the food environment and compare them with the ‘Getting to Equity in Obesity Prevention’ framework of suggested interventions. An electronic literature search was conducted with the assistance of a research librarian encompassing six databases: MEDLINE, PyscINFO, Agricola, ERIC, SocINDEX and ProQuest Dissertations & Theses. A total of thirty sources were identified detailing interventions addressing structural barriers to healthy eating. The majority of nutrition interventions addressing structural racism consisted of policy, systems and/or environmental changes in combination with nutrition education, strategies focused on proximal causes of racial health disparities. Only two articles each targeted the ‘reduce deterrents’ and ‘improve social and economic resources’ aspects of the framework, interventions which may be better suited to addressing structural racism in the food environment. Because African Americans experience high rates of obesity and food insecurity and encounter structural barriers to healthy eating in the food environment, researchers and public health professionals should address this gap in the literature.

High rates of obesity and chronic disease exist in the southeastern United States (US). Knowledge about the attitudes, beliefs, and barriers of the rural low-income Louisiana population regarding healthy eating is limited. Focus Group discussions based on the Theory of Planned Behavior (TPB) were conducted in rural parishes (N = 3) with low-income residents of Louisiana (N = 29). Grounded Theory methods and cross-case analysis were used. The participants were primarily single Black females of age 18–30 years who earned a high school diploma, were employed, and had children. Beliefs included healthy eating was physically beneficial, yet financial impacts and the low palatability of healthy foods were barriers. Professional resources for nutrition education were limited which led to reliance on friends, family, and the internet. Friends and family were positive and negative influences on eating choices. Control beliefs included the high prices and low palatability of healthy foods, the wide availability of Energy Dense Nutrient Poor (EDNP) foods, and low motivation to sustain eating behavior changes. Formative research to optimize campaign distribution channels may improve accessibility to social marketing support and healthy eating resources. Persuasive messages that address control beliefs are needed in social marketing campaigns for rural low-income Louisiana environments.

The prevalence of high obesity in rural communities may result from low access to healthy foods. To improve the local food environment, a multicomponent environmental food store intervention was implemented in 3 Louisiana parishes where obesity prevalence was greater than 40%. The intervention consisted of healthy-food demonstrations, in-store marketing, and encouraging store owners to stock healthy items. We documented aspects of the rural food store climate, such as store size and the store owner's willingness to stock healthy items, that affect improving access to healthy food. We found that although the intervention was not effective in shifting purchasing or dietary habits of customers, positive changes in some food store environments did occur. To maximize the effect that rural food store interventions can have on reducing obesity, it is essential to understand aspects of the rural food store climate.
