ABC News/ReutersCHICAGO (Reuters Health) - U.S. military personnel deployed to Iraq and Afghanistan face an increased risk for developing respiratory symptoms, including persistent or recurring cough and shortness of breath, a large-scale military study has shown.
Combat stress along with air pollution could be to blame, researchers say.
The findings stem from the Millennium Cohort Study, an ongoing study designed to investigate long-term health consequences related to military service.
Among nearly 39,000 military personnel free of persistent or recurring cough or shortness of breath at the outset, 14 percent of "deployers" to the wars in Afghanistan and Iraq suffered new respiratory symptoms compared with 10 percent of "non-deployers" not assigned to those war zones, the researchers found.
