Health Study for a New Generation of U.S. Veterans

National Health Study for a New Generation of U.S. Veterans

The National Health Study for a New Generation of U.S. Veterans, a study of 60,000 Operation Enduring Freedom (OEF), Operation Iraqi Freedom (OIF), and OEF/OIF-era Veterans, is one of the largest scientific research studies of this group of Veterans. The purpose of this study is to:

  • Provide insight on the overall health of recent Veterans
  • Improve VA's understanding of what health services Veterans need
  • Maximize the quality of care that VA offers


More than 20,500 Veterans participated in this study.

Explore the research findings:

  • Cigarette Smoking 42.7% of study participants were non-smokers, 32.5% were current smokers, and 24.8% were former smokers
  • Military Sexual Trauma: 41.5% of women and 4% of men experienced military sexual trauma
  • PTSD: 13.5% of OEF/OIF deployed and non-deployed Veterans screened positive for PTSD
  • Sinusitis, asthma, and bronchitis: OEF/OIF deployed Veterans were 29% more likely to report having sinusitis than non-deployed Veterans
  • Infertility: 15.8% of women and 13.8% of men reported that they had experienced infertility

Researchers continue to analyze data from this study and will share their findings in future publications.


Researchers randomly selected 60,000 Veterans from Department of Defense records of men and women who served in the military between October 2001 and June 2008. The study group included:

  • 30,000 Operation Enduring Freedom/Operation Iraqi Freedom (OEF/OIF) Veterans
  • 30,000 Veterans who served elsewhere during the same time period
  • Representation from each branch of the military
  • Active duty, Reserve, and National Guard members
  • A sample of women Veterans to amount to 20% of the total group


A pilot of this study took place in 2009. The full-scale study began in summer 2009 and data collection closed at the end of 2010.


  • Invited 60,000 Veterans to complete a questionnaire on paper, online, or by telephone
  • Asked 2,000 study participants if they would allow researchers to review their medical records on certain health conditions

The questionnaire covered a wide range of topics, including the following topics:

  • Health risk behaviors: Alcohol use, HIV testing, motorcycle helmet use, seatbelt use, sexual behavior, smoking, and speeding
