Objective: This research describes Gulf War and era veterans enrolled in the Millennium Cohort Study, who were sampled from US military personnel serving in 2000, and compares health characteristics of this sample to a Department of Veterans Affairs study sampled from the complete population.
Methods: Demographics characteristics of this sample were described. Self-reported health characteristics were compared between the two studies.
Results: Gulf War and era veterans in the Millennium Cohort were generally healthier than in the VA study; they had fewer medical conditions and mental health disorders and better self-reported health. In both studies, Gulf War veterans had poorer health outcomes than era veterans.
Conclusion: The Millennium Cohort Study is a unique resource for examining the long-term health effects of Gulf War deployment, particularly comparing deployed and nondeployed personnel and examining illnesses with long latencies.
