Population-level health gains from PM2.5 reduction in an intermediate-pollution region: A multistate analysis of metabolic multimorbidity in Korea.

We examined associations between long-term PM2.5 exposure and metabolic disease progression in Korea, where annual mean PM2.5 concentrations range approximately 10-35 μg/m 3 -exposure levels shared by over 80 countries worldwide-and estimated population-level health gains from PM2.5 reduction.

One-year average PM2.5 concentrations were estimated using Community Multiscale Air Quality modeling.

Dynamic predictions were applied to a nationally representative sample to estimate population-level benefits of reducing PM2.5 to 15, 10, or 5 μg/m 3 over 10 years.
