According to researchers, recent reports suggest U.S. service members who deployed in support of conflicts in Iraq and Afghanistan have higher rates of new-onset asthma than those who did not deploy. Millennium Cohort Study researchers aimed to determine what risk factors may be associated with developing asthma, including combat deployment, among study participants.

The Department of Defense's Millennium Cohort Study is excited to announce the launch of its next follow-up survey for over a quarter of a million service members and veterans who previously enrolled in this landmark study. This longstanding research program, managed by the Naval Health Research Center (NHRC) in San Diego, is the largest and longest-running health study in military history and is designed to understand the long-term health effects of military service.

Analyzing the military and health records of nearly 23,000 Iraq and Afghanistan Veterans, researchers with VA and the Department of Defense found little evidence of a higher risk of respiratory problems among those who served near burn pits.

The Millennium Cohort Study, which was launched in 2001 to help address health outcomes related to Service members' deployments, will soon be increasing its enrollment to more than 200,000 participants. The next survey cycle, which begins this year, will add 50,000 new Cohort members plus 10,000 spouses of Service members to the study.

Recent research from the Millennium Cohort Study found that military personnel who deployed with combat experiences were more likely to report back pain after deployment than service members who deployed without combat experience. Study findings were recently published in the November issue of Spine.

On Aug. 2, 2021, VA announced it would begin processing disability claims for asthma, rhinitis, and sinusitis based on presumed particulate matter exposures during military service in Southwest Asia and certain other areas if these conditions manifested within 10 years of a qualifying period of military service. Much of the data for this significant decision came from the Millennium Cohort Study (MCS), a partnership between the VA Office of Research and Development’s Cooperative Studies Program and the Department of Defense.

Analysis of factors associated with death by suicide during and after military service found that suicide was most common among those with bipolar disorder, depression and alcohol-related problems. Additionally, death by suicide was associated with fewer cumulative days of deployment, the occupation of combat specialist, deployment experience pre-2001 and male gender. Overall, 12.8% of the deaths in the current sample were due to suicide.
