2015 Health Related Behaviors Survey

The Health Related Behaviors Survey (HRBS) is the U.S. Department of Defense (DoD)'s flagship survey for understanding the health, health-related behaviors, and well-being of service members. Fielded periodically for more than 30 years, the HRBS asks questions about health-related issues that can affect force readiness or the ability to meet the demands of military life.

The Defense Health Agency asked RAND to revise and field the 2015 HRBS among active-duty U.S. military service members in the Air Force, Army, Marine Corps, Navy, and Coast Guard between November 2015 and March 2016. Roughly 17,000 service members participated in the survey. The survey examined health-related behaviors in several areas, including:

  • health promotion and disease prevention
  • substance use
  • mental and emotional health
  • physical health and functional limitations
  • sexual behavior and health
  • sexual orientation, transgender identity and health
  • deployment experiences and health.

This site catalogs the project's published work, including summaries by topic and service branch.

The Most-Recent Findings on the Health of the U.S. Military

The findings in the material presented on this site represent the latest and most comprehensive information available on the health of U.S. military service members. The data were collected just over two years ago. RAND researchers will field the survey again in late 2018.

RAND fielded the 2015 HRBS among active-duty U.S. military service members in the Air Force, Army, Marine Corps, Navy, and Coast Guard between November 2015 and April 2016. Participants were randomly selected, and the survey collected roughly 18,000 responses across all of the services.
