Data were analyzed from January 2023 through February 2024.<\/jats:p><\/jats:sec>Exposure<\/jats:title>Duration of deployment to military bases with open burn pits.<\/jats:p><\/jats:sec>Main Outcomes and Measures<\/jats:title>Diagnosis of asthma, chronic obstructive pulmonary disease, interstitial lung disease, hypertension, myocardial infarction, congestive heart failure, ischemic stroke, and hemorrhagic stroke.<\/jats:p><\/jats:sec>Results<\/jats:title>The study population included 459\u202f381 OEF and OIF veterans (mean [SD] age, 31.6 [8.7] years; 399\u202f754 [87.0%] male). Median (IQR) follow-up from end of deployment was 10.9 (9.4-12.7) years. For every 100 days of deployment to bases with burn pits, veterans experienced increased adjusted odds for asthma (adjusted odds ratio [aOR], 1.01; 95% CI, 1.01-1.02), chronic obstructive pulmonary disease (aOR, 1.04; 95% CI, 1.02-1.07), hypertension (aOR, 1.02; 95% CI, 1.02-1.03), and ischemic stroke (aOR, 1.06; 95% CI, 0.97-1.14). Odds of interstitial lung disease, myocardial infarction, congestive heart failure, or hemorrhagic stroke were not increased. Results based on tertiles of duration of burn pit exposures were consistent with those from the continuous exposure measures.<\/jats:p><\/jats:sec>Conclusions and Relevance<\/jats:title>In this cohort study, prolonged deployment to military bases with open burn pits was associated with increased risk of developing asthma, COPD, and hypertension. The results also point to a possible increased risk in ischemic stroke. The novel ability to use integrated data on deployment and health outcomes provides a model for additional studies of the health impact of environmental exposures during military service.<\/jats:p><\/jats:sec>","DOI":"10.1001\/jamanetworkopen.2024.7629","type":"journal-article","created":{"date-parts":[[2024,4,25]],"date-time":"2024-04-25T15:33:41Z","timestamp":1714059221000},"page":"e247629","source":"Crossref","is-referenced-by-count":47,"title":["Deployment
