Food system dynamics structuring nutrition equity in racialized urban neighborhoods.

BACKGROUND: The food system is a social determinant of health and a leverage point for reducing diet-related racial inequities. Yet, food system interventions have not resulted in sustained improvement in dietary outcomes for underrepresented minorities living in neighborhoods with a history of disinvestment. Research is needed to illuminate the dynamics structuring food systems in racialized neighborhoods to inform intervention development. OBJECTIVES: To conduct participatory research examining the complexity and inequity of food systems in historically redlined neighborhoods to identify feedback mechanisms to leverage in efforts to transform system outcomes for racial equity. METHODS: We conducted a mixed-methods study in Cleveland, Ohio, USA from 2018 to 2021 using participatory system dynamic modeling with 30 academic and community partners, in-depth qualitative interviews with 22 key stakeholders, and public convenings with 250 local food policy council affiliates. Data were synthesized into causal loop diagrams depicting feedback mechanisms reinforcing or balancing neighborhood-level food system dynamics. RESULTS: We identified 10 feedback mechanisms structuring nutrition equity, which was identified as a meta-goal for food systems in racialized neighborhoods. Feedback mechanisms were organized in 3 domains: 1) meeting basic food needs with dignity (i.e., side hustle, government benefits, emergency food assistance, stigma, and stereotypes); 2) local food supply and demand dynamics (i.e., healthy food retail, job security, food culture, and norms); and 3) community empowerment and food sovereignty (i.e., community power, urban agriculture, risk of gentrification). Five exogenous factors moderate feedback dynamics: neighborhood crisis, neighborhood investments, household costs, government benefit funding, and voter participation. CONCLUSIONS: We identified nutrition equity as an overarching goal for local food systems, which reflects a state of having freedom, agency, and dignity in food traditions resulting in people and communities healthy in body, mind, and spirit. It is a transformative goal designed to spur system-level interventions that further racial equity through improved local food system dynamics.

Fixes that Fail: A system archetype for examining racialized structures within the food system.

Access to fresh and healthy food within a neighborhood has been identified as a social mechanism contributing to community health. Grounded in the understanding that challenges related to equity within a food system are both structural and systemic, our research demonstrates how systems thinking can further understandings of food system complexity. Within systems thinking, we provide an illustration of how system archetypes offer an analytic tool for examining complex community issues. We map semi-structured interview data from community stakeholders (N = 22) to the "Fixes that Fail" system archetype to illuminate systemic challenges, such as incarceration and poverty, that structure food system inequity in urban communities. Within our research, the "Fixes that Fail" archetype provided a narrative interpretive tool for unveiling complexity within the food system and interdependencies with racialized systems such as criminal justice and labor markets. This system archetype provided an accessible approach for generating narratives about systemic complexity, the production of inequity through racialized forces, and opportunities for transformation.

A relational approach to evaluate food environments finds that the proximate food environment matters for those who use it.

Using a relational approach, this study investigates whether shopping close to home moderates the relationship between the proximate food environment and diet. To address this question, we develop the proximate food retail quality (PFRQ) score, an inverse-distance weighted measure of all food retailers within a resident's neighborhood that incorporates audit data of each food retailer. This study relies on data collected through 24-h dietary recalls and psychosocial surveys administered to 449 adults in two socioeconomically matched neighborhoods. Food retailer audits collected data on the availability, price, and quality of healthful foods. Seventy-one percent of study participants report conducting at least 50% of their food shopping within approximately one mile of their home. Household income and education are associated with likelihood to shop close to home, while access to a personal vehicle is not. Finally, results suggest that, for residents who shop primarily close to home, a one unit increase in proximate food retail environment score is associated with a 17.2-point increase in HEI-2010 score, a measure of overall diet quality that ranges from zero to 100. This study suggests that the food environment matters for those who use it and that a low-quality proximate food environment can amplify individual disadvantage.

The power to convene: making sense of the power of food movement organizations in governance processes in the Global North.

Dominant food systems, based on industrial methods and corporate control, are in a state of flux. To enable the transition towards more sustainable and just food systems, food movements are claiming new roles in governance. These movements, and the initiatives they spearhead, are associated with a range of labels (e.g., food sovereignty, food justice, and community food security) and use a variety of strategies to enact change. In this paper, we use the concept of relational fields to conduct a post-hoc analysis of nine cases, examining how social movement organizations and other actors actively create new deliberative governance spaces. We argue that successes are related to the "power to convene," a process-oriented approach that increases movements' capacity to mobilize; leverage different types of power; and integrate, coordinate, and build a systems-oriented vision. The power to convene and create deliberative spaces is demonstrated in a variety of contexts and often results in outcomes that further movement aims, including policy change and repositioning food movement actors vis-à-vis others in the field. Our findings suggest that success is not only measured as policy outcomes, but as an advantageous repositioning of social movement actors that enables them to be part of governance processes beyond simple policy advocacy.

Emergency Food Provision for Children and Families during the COVID-19 Pandemic: Examples from Five U.S. Cities.

As lockdown and school closure policies were implemented in response to the coronavirus, the federal government provided funding and relaxed its rules to support emergency food provision, but not guidance on best practices for effectiveness. Accordingly, cities developed a diverse patchwork of emergency feeding programs. This article uses qualitative data to provide insight into emergency food provision developed in five cities to serve children and families. Based on our qualitative analysis, we find that the effectiveness of local approaches appears to depend on: (i) cross-sector collaboration, (ii) supply chains, and (iii) addressing gaps in service to increased risk populations.

Socioecological Path Analytic Model of Diet Quality among Residents in Two Urban Food Deserts.

BACKGROUND: Diet is critical to chronic disease prevention, yet there are persistent disparities in diet quality among Americans. The socioecological model suggests multiple factors, operating at multiple levels, influence diet quality. OBJECTIVE: The goal was to model direct and indirect relationships among healthy eating identity, perceived control of healthy eating, social support for healthy eating, food retail choice block scores, perceptions of healthy food availability, and food shopping behaviors and diet quality measured using Healthy Eating Index-2010 scores (HEI-2010) for residents living in two urban communities defined as food deserts. DESIGN: A cross-sectional design was used including data collected via self-reported surveys, 24-dietary recalls, and through objective observations of food retail environments. PARTICIPANTS/SETTING: Data collection occurred in 2015-2016 in two low-income communities in Cleveland (n=243) and Columbus (n=244), OH. MAIN OUTCOME MEASURE: HEI-2010 scores were calculated based on the average of three 24-hour dietary recalls using the Nutrition Data System for Research. ANALYSIS: Separate path models, controlled for income, were run for each community. Analysis was guided by a conceptual model with 15 hypothesized direct and indirect effects on HEI-2010 scores. Associations were considered statistically significant at P<0.05 and P<0.10 because of modest sample sizes in each community. RESULTS: Across both models, significant direct effects on HEI-2010 scores included healthy eating identity (ß=.295, Cleveland; ß=.297, Columbus, P<0.05) and distance traveled to primary food store (ß=.111, Cleveland, P<0.10; ß=.175, Columbus, P<0.05). Perceptions of healthy food availability had a significant, inverse effect in the Columbus model (ß=-.125, P<0.05). The models explained greater variance in HEI-2010 scores for the Columbus community compared with Cleveland (R2=.282 and R2=.152, respectively). CONCLUSIONS: Findings highlight the need for tailored dietary intervention approaches even within demographically comparable communities. Interventions aimed at improving diet quality among residents living in food deserts may need to focus on enhancing healthy eating identity using culturally relevant approaches while at the same time addressing the need for transportation supports to access healthy food retailers located farther away.

A food hub to address healthy food access gaps: Residents' preferences.

Interventions aimed at improving access to healthy food in low-income communities should consider the preferences of residents. Household food shoppers in two urban, low-income communities were asked about their preferences for vendors at, and qualities of, a potential nearby food hub. Universally, participants preferred availability of whole foods, primarily fruits and vegetables. They also favored cleanliness, quality, and affordability. The demographics and preferences of potential customers raise central issues that would need to be integrated into the development of a food hub, namely affordability (likely through subsidization), attention to accommodation and cultural accessibility, and programming that builds community.
