CSP #505: Millennium Cohort Study


CSP #505 is merging data from the Department of Defense’s (DoD) Millennium Cohort Study1 with VA health care and benefits data to create a single resource that presents a more complete picture of the military to civilian life cycle experienced by Veterans. This resource can be used to identify potential causes of military, Veteran, and national healthcare problems, especially those stemming from military service, and to explore innovative and effective solutions.

Request access to data

Qualified researchers can request access to the merged Millennium Cohort – VA data for secondary data analysis. Data access is managed by CSP #505 staff in collaboration with the Millennium Cohort Study team at the DoD Naval Health Research Center (NHRC). 

After the initial access request, researchers are required to submit a study proposal. Those are reviewed on a quarterly schedule and the next meeting is September 21, 2021. Proposal submissions must be emailed to the CSP #505 Project Manager by 5pm Pacific on August 20, 2021.

We expect 2021 meeting dates to take place in March, June, September and December and the submission deadline for each will be one month prior. We’ll update this page when those dates are confirmed. 

Executive Committee

The Executive Committee is the decision-making group who reviews and makes recommendations on all proposed study changes, use of study data, potential publications, and other operational parts of the study.

Looking to the future

We’re working to create seamless, ongoing, bilateral data sharing between CSP #505 and the Millennium Cohort Study. This will increase the value and utilization of the data for both VA and DoD.

DoD Millennium Cohort Study overview

The Millennium Cohort Study1 launched in July 2001 and is conducted at the Naval Health Research Center in San Diego, CA. Study participation includes completing comprehensive questionnaires about health, lifestyle, and military experiences every three years. Questionnaire data is then linked with other data sources. The study plans to continue longitudinal follow-up and triennial data collection on participants for 65 years.

As of July 2019, 201,620 study participants have enrolled in the Cohort over the course of four enrollment panels. Initial participants were sampled from a cross-section of the entire military and included oversampling for women, Reservists, and those who had previously deployed to the conflicts in Bosnia, Kosovo, and SW Asia (the most recent deployments at that time).

Subsequent enrollment panels have focused on newer accessions to the military, while oversampling for women and Marines. The heightened operational tempo since the September 11, 2001 terrorist attacks precluded the need to oversample for deployers and Reservists in later enrollment panels. 

The Millennium Cohort Study expanded in 2011 to include the Millennium Cohort Family Study1. The Family Study enrolled 9,872 spouses of Millennium Cohort Study participants from enrollment Panel 4. 

Future enrollment panels are planned for both studies. The Millennium Cohort Study began enrolling Panel 5 in fall of 2020 with a goal of 50,000 new enrollees. Enrollment is expected to continue through mid-to-late 2021.   

DoD Millennium Cohort Study origin

The need for a prospective, longitudinal cohort study of military services members became apparent following the first Gulf War, when the lack of baseline data was a serious limitation to designing studies to assess Gulf War Illness. 

The Millennium Cohort Study was included in the 1999 Strom Thurmond National Defense Authorization Act at the recommendation of several national agencies, including VA, DoD, the Armed Forces Epidemiological Board, and the Institute of Medicine. It established “a longitudinal study to evaluate data on the health conditions of members of the armed forces upon their return from deployment.”
