Abstract
Purpose
The objective of this study was to evaluate the association between blood cadmium (Cd) and moderate-to-severe glomerular dysfunction in a Korean population using a representative sample.
Methods
A cross-sectional study was used to evaluate the association between blood Cd and glomerular dysfunction. Based on the Korean National Health and Nutrition Examination Survey (2005–2008), individual blood Cd was measured in 2,992 adults, aged between 20 and 65.
Results
After adjusting for survey years, age, sociodemographic factors, and health behaviors, the odds ratio for moderate-to-severe glomerular dysfunction (<60 mL/min per 1.73 m2) was 1.97 (95% CI: 1.28–3.07) when comparing the highest with the lowest blood Cd quartile in Korean women. However, in Korean men, there was no association between blood Cd and moderate-to-severe glomerular dysfunction.
Conclusions
These findings support the consideration of Cd as a risk factor for glomerular dysfunction in the female population. Furthermore, environmental heavy metal monitoring and an institutional strategy should be implemented to reduce Cd exposure in the general population.
