About The Study: In this cohort study of the U.S. Medicare population, specific fine particulate matter (PM2.5) components (sulfate, elemental carbon, and soil dust) were associated with increased depression risk in older adults, particularly those with preexisting comorbidities. These findings underscore the importance of targeted regulation of harmful PM2.5 components to protect vulnerable populations.
