Reduced access to affordable healthy foods is linked to higher rates of chronic diseases in low-income urban settings. The authors conduct a feasibility study of an environmental intervention (Baltimore Healthy Stores) in seven corner stores owned by Korean Americans and two supermarkets in low-income East Baltimore. The goal is to increase the availability of healthy food options and to promote them at the point of purchase. The process evaluation is conducted largely by external evaluators. Participating stores stock promoted foods, and print materials are displayed with moderate to high fidelity. Interactive consumer taste tests are implemented with high reach and dose. Materials developed specifically for Korean American corner store owners are implemented with moderate to high fidelity and dose. Results indicate that small food store-based intervention programs are feasible to implement and are a viable means of increasing healthy food availability and a good location for point-of-purchase promotions in low-income urban settings.

    • "Many individuals and especially children are, however, neophobic and hesitant to try new, healthful foods [32,33]. Although taste testing has been a component of successful school [12,34-37] and grocery store-based [38-41] multicomponent dietary interventions, the independent impact of providing food samples to nudge selection of healthful products is not clear. Similarly, descriptive menu labels are a simple, low-cost strategy used by industry to enhance the attractiveness of menu items, but were found to be relatively untested for their independent potential to cue healthier dietary choices [14,42].

    ABSTRACT: Nudging is an approach to environmental change that alters social and physical environments to shift behaviors in positive, self-interested directions. Evidence indicates that eating is largely an automatic behavior governed by environmental cues, suggesting that it might be possible to nudge healthier dietary behaviors. This study assessed the comparative and additive efficacy of two nudges and an economic incentive in supporting healthy food purchases by patrons at a recreational swimming pool. An initial pre-intervention period was followed by three successive and additive interventions that promoted sales of healthy items through: signage, taste testing, and 30% price reductions; concluding with a return to baseline conditions. Each period was 8 days in length. The primary outcome was the change in the proportion of healthy items sold in the intervention periods relative to pre- and post-intervention in the full sample, and in a subsample of patrons whose purchases were directly observed. Secondary outcomes included change in the caloric value of purchases, change in revenues and gross profits, and qualitative process observations. Data were analyzed using analysis of covariance, chi-square tests and thematic content analysis. Healthy items represented 41% of sales and were significantly lower than sales of unhealthy items (p < 0.0001). In the full sample, sales of healthy items did not differ across periods, whereas in the subsample, sales of healthy items increased by 30% when a signage + taste testing intervention was implemented (p < 0.01). This increase was maintained when prices of healthy items were reduced by 30%, and when all interventions were removed. When adults were alone they purchased more healthy items compared to when children were present during food purchases (p < 0.001), however parental choices were not substantially better than choices made by children alone. This study found mixed evidence for the efficacy of nudging in cueing healthier dietary behaviors. Moreover, price reductions appeared ineffectual in this setting. Our findings point to complex, context-specific patterns of effectiveness and suggest that nudging should not supplant the use of other strategies that have proven to promote healthier dietary behaviors.

    ABSTRACT: Prepared food sources, including fast food restaurants and carry-outs, are common in low-income urban areas. These establishments provide foods high in calories, sugar, fat, and sodium. The aims of the study were to (1) describe the development and implementation of a carry-out intervention to provide and promote healthy food choices in prepared food sources, and (2) to assess its feasibility through a process evaluation. To promote healthy eating in this setting, a culturally appropriate intervention was developed based on formative research from direct observation, interviews and focus groups. We implemented a 7-month feasibility trial in 8 carry-outs (4 intervention and 4 comparison) in low-income neighborhoods in Baltimore, MD. The trial included three phases: 1) Improving menu boards and labeling to promote healthier items; 2) Promoting healthy sides and beverages and introducing new items; and 3) Introducing affordable healthier combo meals and improving food preparation methods. A process evaluation was conducted to assess intervention reach, dose received, and fidelity using sales receipts, carry-out visit observations, and an intervention exposure assessment. On average, Baltimore Healthy Carry-outs (BHC) increased customer reach at intervention carry-outs; purchases increased by 36.8% at the end of the study compared to baseline. Additionally, menu boards and labels were seen by 100.0% and 84.2% of individuals (n = 101), respectively, at study completion compared to baseline. Customers reported purchasing specific foods due to the presence of a photo on the menu board (65.3%) or menu labeling (42.6%), suggesting moderate to high dose received. Promoted entree availability and revised menu and poster presence all demonstrated high fidelity and feasibility. The results suggest that BHC is a culturally acceptable intervention. The program was also immediately adopted by the Baltimore City Food Policy Initiative as a city-wide intervention in its public markets.

    ABSTRACT: Obesity and other diet-related chronic diseases are directly related to the food environment. We describe how to better assess the food environment in specific ethnic minority settings for designing and implementing interventions, based on a review of our previous work on the food environment in American Indian reservations, Canadian First Nations reserves, the Republic of the Marshall Islands, and inner-city Baltimore. The types of food stores available within each setting and the range of healthy foods available varied greatly across these geographic regions. In all settings, proximity to food stores/supermarkets, cost, and limited availability of healthful foods were common features, which limited access to health-promoting food options. Features specific to each population should be considered in an assessment of the food environment, including physical (e.g., openness of stores, mix of types of food sources); consumer (e.g., adequacy of the food supply, seasonal factors); and social (e.g., inter-household food sharing, perceptions of food quality, language differences) aspects. The food environments common in low-income ethnic subpopulations require special focus and consideration due to the vulnerability of the populations and to specific and unique aspects of each setting.
