Research Studies on Military Exposures
VA conducts or sponsors research studies on Veterans’ illnesses related to military exposures. Current studies are listed below.
Operation Enduring Freedom (OEF), Operation Iraqi Freedom (OIF) and Operation New Dawn (OND)
- National Health Study for a New Generation of U.S. Veterans
The 10-year study collects data on health risk behavior, general health, health care utilization, and potential exposures of 60,000 Veterans from Operations Enduring Freedom and Iraqi Freedom.
- Burn Pits
VA is sponsoring several in-depth studies on possible health effects of open burn pits in military settings in Afghanistan and Iraq.
- Suicide Risk and Risk of Death
Researchers looked at the risk of suicide and death among 1.3 million Veterans who served in Iraq or Afghanistan between 2001-2007.
- Health Care Use
Researchers studied VA health care use among OEF/OIF/OND Veterans between 2002-2010.
Gulf-Era Twin Registry
VA is collecting data on the military and life experiences of up to 12,000 twins who separated from military service after 2001. The Gulf-Era Twin Registry will help researchers identify Veterans who are eligible for future research studies.
Gulf War Era Veterans with 1990-1991 service
- Follow-up Study of a National Cohort of Gulf War and Gulf Era Veterans
Researchers contacted approximately 30,000 Gulf War and Gulf War-era Veterans for the third time since 1995 to learn about the health of these Veterans over time.
- Longitudinal Health Study of Gulf War Era Veterans
Researchers evaluated health data from 5,469 Gulf War-deployed Veterans and 3,353 Veterans who served elsewhere during the Gulf War. These Veterans participated in an initial survey in 1995 and a second survey in 2005.
- Post-War Mortality from Neurologic Diseases in Gulf War Veterans
Researchers are investigating the risk of post-war mortality from neurological disease among 620,000 Gulf War Veterans and 750,000 non-Gulf War Veterans. Gulf War Veterans may be at increased risk for amyotrophic lateral sclerosis (ALS), multiple sclerosis, Parkinson's disease, or brain cancer.

Vietnam Era Veterans
- Army Chemical Corps Vietnam-Era Veterans Health Study
Researchers are studying 4,000 Veterans who served in the U.S. Army Chemical Corps sometime between 1965-1973 to determine if high blood pressure (hypertension) and chronic obstructive pulmonary disease (COPD) are related to Agent Orange exposure during Vietnam.
