The Millennium Cohort Study

"I just received my coin the other day. How beautiful! I really appreciate the gift. Thanks for it and the hard work you folks do for me and my fellow veterans. We really appreciate it. I'm thankful I can be of service and hope to be until the end of your study."

The Millennium Cohort Study is the largest prospective health project in military history. It is designed to evaluate the long-term health effects of military service, including deployments. The Department of Defense recognized after the 1991 Gulf War that there was a need to collect more information about the long-term health of service members. The Millennium Cohort Study was designed to address that critical need, and the study was launched by 2001.

Funded by the Department of Defense, and supported by military, Department of Veterans Affairs, and civilian researchers, almost 150,000 people are already participating in this groundbreaking study. As force health protection continues to be a priority for the future of the United States military, the Millennium Cohort Study will be providing critical information towards enhancing the long-term health of future generations of military members.

The Millennium Cohort Study is a Department of Defense research project at the DoD Center for Deployment Health Research, located in San Diego, California.
