Association of socioeconomic status with kidney function decline and mortality among older Korean adults: a nationwide cohort study

Key takeaways

This large study followed 784,224 older adults in Korea. It found that people with lower income had faster kidney decline and higher death rates. This shows a link, but it does not prove that income directly causes kidney damage.
