Understanding CKDu risk factors in agricultural Central America

Official title: Exploring risk factors and predictors of endemic CKDu in agricultural regions of four Central America countries

Funded at Universidad Nacional, Costa Rica · NIH-11520955 · Data updated 2026-11-12

This grant tests what factors put agricultural workers in four Central American countries at risk for chronic kidney disease of unknown origin (CKDu) and what predicts kidney function decline.

Who could benefit from this research

Could help

Adults in rural Central American communities with exposure to agricultural work, heat stress, and related risk factors, including both those with CKDu and those without.

Less likely to help

Individuals not in CKDu-endemic agricultural settings or without kidney-related concerns may not directly benefit.

What this research studies

CKDu affects young workers in rural Central America, and this project follows people in Costa Rica, Panama, Nicaragua, and Guatemala to find what environmental, social, and biological factors are linked to kidney decline. Researchers will collect health data and markers from blood and tissue, study exposure to heat, heavy labor, toxins, and infections, and bank samples for future biomarker analysis. The study uses field epidemiology to identify cases and controls and to track participants over time, including those with and without CKDu. Results could help pinpoint modifiable risks and improve prevention strategies for affected communities.

Why it matters

Potential benefit: If successful, the research could lead to earlier detection and prevention of CKDu risk among agricultural workers.

How similar studies have gone: Previous CKDu research has identified associations, but this project adds comprehensive risk-factor analysis and biomarker work in a new, multi-country Central American context.
