Vietnam Era Health Retrospective Observational Study

The Vietnam Era Health Retrospective Observational Study (VE-HEROeS) is a nationwide study that will assess the current health and well-being of Vietnam Veterans, Blue Water Navy Veterans, and Veterans who served elsewhere during the Vietnam Era (1961–1975). This study will also compare the health of these Veterans to similarly aged U.S. residents who never served in the military.

Researchers will look closely at neurologic conditions and hepatitis C infection as a part of this study.

Researchers are still accepting surveys from individuals who were invited to participate in this study. If you have been selected, VA encourages you to return your survey. Questions? Call our VE-HEROeS survey assistance center at 1-855-434-5102.

This study includes a questionnaire for everyone and medical records review for a smaller group of participants. The VE-HEROeS questionnaire includes the following topics:

  • Military service: service experience, combat experience, chemical and other exposures, re-entry into civilian life, or no military service
  • General health: neurologic conditions, infections, presumptive conditions, cancer, hypertension, posttraumatic stress disorder, and depression
  • Aging: memory, reasoning, and limitations
  • Lifestyle: tobacco use, health care use, living arrangements, and health experiences of descendants

Participant Selection

VA is inviting approximately 43,000 Vietnam and Vietnam Era Veterans, and approximately 11,000 members of the general population to participate in VE-HEROeS. These individuals were scientifically selected from the Veteran community and U.S. population to represent others with similar characteristics. Because each selected individual represents other comparable people, we are not able to accept volunteers for this study.
