Risk factors for chronic kidney disease in Central American farm communities

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

NIH-funded research Universidad Nacional, Costa Rica · NIH-11162371

This project looks for causes and early warning signs of chronic kidney disease affecting young agricultural workers in Costa Rica, Panama, Nicaragua, and Guatemala by following people over time and testing blood, urine, and other samples.

What this research studies

If you join, you'll be enrolled along with other people from rural communities in Costa Rica, Panama, Nicaragua, and Guatemala and followed over several years. The team will collect health information, work histories, and samples such as blood and urine, and measure kidney function over time. They will record exposures like heat stress, agricultural chemicals, heavy metals, and possible infections, and bank samples for genetic and biomarker testing. This approach aims to find early warning signs and potentially preventable causes of CKDu.

Who could benefit from this research

Good fit: Adults and young adults living or working in agricultural communities in the four Central American countries, including people with early-stage CKDu and those without known kidney disease, are the ideal candidates.

Not a fit: People who live outside the four participating countries or those with advanced, end-stage kidney disease on dialysis are unlikely to get direct benefit from this project.

Why it matters

Potential benefit: Could identify preventable causes and earlier markers of kidney injury so more people can be protected or treated sooner.

How similar studies have performed: Previous community-based studies and efforts within the NIH CURE consortium have suggested links to heat stress and toxins but have not yet produced a single definitive cause, so this builds on prior work while exploring new biomarkers and exposures.
