RESUMO
BACKGROUND: Households experiencing food insecurity may use dynamic strategies to meet food needs. Yet, the relationship between household food sourcing behaviors and food security, particularly in rural settings, is understudied. OBJECTIVE: To identify food sourcing patterns and their associations with food insecurity among households in rural Appalachian Ohio during the COVID-19 pandemic. DESIGN: Survey data were collected from a cohort of households in Athens County, Ohio in July 2020, October 2020, January 2021, and April 2021. PARTICIPANTS/SETTING: The sample included 663 households with household food sourcing and food security information for ≥1 survey wave. MAIN OUTCOME MEASURES: Household food sourcing patterns. Households reported the frequency with which they obtained food from various retailers and charitable sources, classified as supercenters, supermarkets, convenience stores, farmers' markets, or charitable sources. STATISTICAL ANALYSES: Principal component analysis was used to identify food sourcing patterns. Linear mixed models were used to assess changes in food sourcing behaviors over the study period and to determine whether food sourcing behaviors differed according to food security status. RESULTS: Two patterns were identified: 1) Convenience Stores and Charitable Food, 2) Supermarkets and Farmers' Markets, not Supercenters. Relative to July 2020, alignment of households' food sourcing behaviors with the "Supermarkets and Farmers' Markets, not Supercenters" pattern was higher in October 2020 (ß=0.07; 95% CI: 0.02, 0.12) and alignment with the "Convenience Stores and Charitable Food" pattern was lower in April 2021 (ß=-0.06; 95% CI: -0.11, -0.02). Compared to food-secure households, food sourcing behaviors of food-insecure households were more closely aligned with the "Convenience Stores and Charitable Food" pattern (ß=0.07; 95% CI: 0.00, 0.13); no statistically significant difference in scores was observed for the "Supermarkets and Farmers' Markets, not Supercenters" pattern (ß=-0.07; 95% CI: -0.15, 0.02). CONCLUSIONS: These findings support efforts to increase access to healthy, affordable options at venues where food-insecure households may be likely to obtain food, such as convenience stores and charitable sources.
RESUMO
Food and nutrition insecurity disproportionately impact low-income households in the United States, contributing to higher rates of chronic diseases among this population. Addressing this challenge is complex because of various factors affecting the availability and accessibility of nutritious food. Short value chain (SVC) models, informally known as local food systems, offer a systemic approach that aims to optimize resources and align values throughout and beyond the food supply chain. Although specific SVC interventions, such as farmers markets, have been studied individually, a comprehensive review of SVC models was pursued to evaluate their relative impact on food security, fruit and vegetable intake, diet quality, health-related markers, and barriers and facilitators to participation among low-income households. Our systematic literature search identified 37 articles representing 34 studies from 2000-2020. Quantitative, qualitative, and mixed-method studies revealed that farmers market interventions had been evaluated more extensively than other SVC models (i.e., produce prescription programs, community-supported agriculture, mobile markets, food hubs, farm stands, and farm-to-school). Fruit and vegetable intake was the most measured outcome; other outcomes were less explored or not measured at all. Qualitative insights highlighted common barriers to SVC use, such as lack of program awareness, limited accessibility, and cultural incongruence, whereas facilitators included health-promoting environments, community cohesion, financial incentives, and high-quality produce. Social marketing and dynamic nutrition education appeared to yield positive program outcomes. Financial incentives were used in many studies, warranting further investigation into optimal amounts across varying environmental contexts. SVC models are increasingly germane to national goals across the agriculture, social, and health care sectors. This review advances the understanding of key knowledge gaps related to their implementation and impact; it emphasizes the need for research to analyze SVC potential comprehensively across the rural-urban continuum and among diverse communities through long-term studies of measurable health impact and mixed-method studies investigating implementation best practices. This trial was registered at PROSPERO as CRD42020206532.
