Abstract

This study aimed to examine associations between deployment to US military bases with open burn pits and mental health conditions and injury-related mortality among veterans. We analyzed a cohort of 439,919 US Army and Air Force Veterans deployed to Operation Enduring Freedom or Operation Iraqi Freedom (2001-2011). Deployment records were linked with Veterans Health Administration data. Exposure was defined as cumulative days deployed to bases with burn pits. Deployment duration to burn pit-exposed bases are associated with increased risk of postdeployment diagnoses of posttraumatic stress disorder, intracranial damage and injuries, and unintentional injury-related mortality. Cumulative exposure to open burn pits was associated with elevated risk of long-term psychiatric and injury-related outcomes among veterans. These findings highlight the need for continued monitoring and support for service members exposed to environmental hazards during military deployment.
