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 active-duty service members.

  • It allows leadership to better understand the readiness of the force.
  • It is used to facilitate benchmarking in combination with Healthy People benchmarks (designed for the general U.S. population).
  • Results are weighted to represent the 2015 active-duty force by service branch, pay grade, and gender.

Comparison to U.S. General Population

The 2015 HRBS shows that active-duty service members generally have better health and health-related behaviors than the U.S. adult population.

Exceptions include binge and hazardous alcohol use, common mental health conditions, and sleep problems.

Nicotine use is comparable to civilian populations; cigarette use is down, but e-cigarette use has significantly increased since the 2011 HRBS.

Obesity compares favorably to civilian populations and has been largely stable over recent HRBSs; percentage overweight is a possible concern, but measurement method may be an issue.

HIV testing among those at high risk may be an opportunity for improvement.

Currently, there are no military-appropriate benchmarks for comparison purposes.

Development of military-appropriate population benchmarks may facilitate goal-setting, command visibility, and incremental improvements in health-related readiness.


A low overall response rate (8.6%) suggests that the results should be interpreted with caution and in conjunction with other existing data. New ways to improve survey response rates are needed, including focusing survey content, shifting to a confidential rather than anonymous survey, and addressing information technology issues related to use of a non-DoD email address. The above comparisons to the general adult population do not control for differences in demographic composition.
