Urban Food Deserts and Cardiovascular Health: Evaluating the Impact of Nutritional Inequities on Elderly Populations in Santiago : Evaluating the Impact of Nutritional Inequities on Elderly Populations in Santiago

Abstract

Featured Application: (1) The methodological approach based on multiscale geographically weighted regression provides a nuanced understanding of how urban factors influence health disparities. (2) The findings highlight the importance of food accessibility as a determinant of health, reinforcing the need for interdisciplinary approaches that combine public health, urban planning, and nutrition science. (3) Policymakers can use this data to identify priority areas for improving food access, particularly in economically disadvantaged neighborhoods. This could involve incentivizing grocery stores and markets to establish themselves in underserved areas or enhancing public transportation links to existing food resources. (4) The call for sustainable food systems to support public health highlights the importance of long-term strategies that ensure consistent access to healthy, affordable food. This can influence agricultural policies, support for local food producers, and the promotion of urban agriculture initiatives. This study examines the link between food deserts and cardiovascular health in older adults in Santiago’s Metropolitan Region, Chile. As the population ages and chronic diseases rise, understanding the impact of food accessibility on health is essential. Using multiscale geographically weighted regression, we analyzed data from the Cardiovascular Health Program, socioeconomic indicators, and food desert maps, sourced from the Chilean Ministry of Health and other databases. Spatial analysis, including Voronoi diagrams, assessed the influence of food deserts on health outcomes. Findings show a significant correlation between limited access to healthy foods and higher cardiovascular disease rates, especially in economically disadvantaged areas. The regression model is significant to contribute to the explanation of disease prevalence, emphasizing the impact of food availability on health. This study highlights the importance of considering spatial factors in urban planning and public health policies. By showcasing the role of food environments in health disparities, it advocates for integrated health interventions. Targeted urban planning to address food deserts can enhance access to healthy foods, improving cardiovascular health and well-being among Santiago’s elderly. The findings provide insights for policymakers to create healthier urban environments and stress the need for sustainable food systems to support public health.

Este estudio examina la relación entre los desiertos alimentarios y la salud cardiovascular en adultos mayores de la Región Metropolitana de Santiago, Chile. A medida que la población envejece y aumentan las enfermedades crónicas, es esencial comprender el impacto de la accesibilidad a los alimentos en la salud. Utilizando regresión multiescala ponderada geográficamente, analizamos datos del Programa de Salud Cardiovascular, indicadores socioeconómicos y mapas de desiertos alimentarios, obtenidos del Ministerio de Salud chileno y otras bases de datos. El análisis espacial, incluidos los diagramas de Voronoi, evaluó la influencia de los desiertos alimentarios en los resultados sanitarios. Los resultados muestran una correlación significativa entre el acceso limitado a alimentos sanos y tasas más altas de enfermedades cardiovasculares, especialmente en zonas económicamente desfavorecidas. El modelo de regresión es significativo para contribuir a la explicación de la prevalencia de enfermedades, destacando el impacto de la disponibilidad de alimentos en la salud. Este estudio pone de relieve la importancia de considerar los factores espaciales en la planificación urbana y las políticas de salud pública. Al mostrar el papel de los entornos alimentarios en las disparidades sanitarias, aboga por intervenciones sanitarias integradas. Una planificación urbana específica para hacer frente a los desiertos alimentarios puede mejorar el acceso a alimentos sanos y la salud cardiovascular y el bienestar de los ancianos de Santiago. Las conclusiones aportan ideas a los responsables políticos para crear entornos urbanos más sanos y subrayan la necesidad de sistemas alimentarios sostenibles para apoyar la salud pública.
