The Population Renal Health paradigm (Burgos-Calderón, Depine, and Aroca- Martínez, 2021) shifts from individual risk assessment to population and territorial vulnerability analysis by integrating social determinants of health (SDOH). To operationalize this approach, the Population Vulnerability Index (PVI) was developed as a quantitative geospatial tool that measures SDOH across the Colombian Caribbean region, enabling systematic comparison of territorial vulnerability. In parallel, the RENELUP registry collects and georeferences LN cases throughout Colombia. This study cross-references RENELUP data from the city of Barranquilla with PVI scores to examine how SDOH influence disease distribution patterns in this urban setting.pdfengAttribution-NonCommercial-NoDerivatives 4.0 Internationalinfo:eu-repo/semantics/openAccessinfo:eu-repo/semantics/articlehttps://doi.org/10.1016/j.ekir.2026.105071https://www.kireports.org/article/S2468-0249(26)01302-1/fulltext
