Background: This research explores the healthy soldier effect (HSE) - a lower mortality risk among Veterans relative to the general population--in United States (U.S.) Veterans deployed in support of operations in Iraq and Afghanistan (OEF/OIF/OND). Methods: Using U.S. Department of Veterans Affairs (VA) and DOD administrative data, we identified Veterans deployed in support of OEF/OIF/OND during 2002 and 2011. Indirect standardization was used to compare VA and DOD cohorts to the U.S. population. Results: The overall VA SMR of 2.8 (95% Confidence Interval (CI) 2.8-2.9), VA Utilizer SMR of 3.2 (95% CI 3.1-3.3), VA non-Utilizer SMR of 0.9 (95% CI 0.8-1.1) and DOD SMR of 1.5 [95% CI 1.4-1.5) provide no evidence of HSE in these cohorts relative to the U.S. standard population. Conclusions: No support was found for HSE among U.S. Veterans of OEF/OIF/OND. These findings may be attributable to post-deployment risk taking behavior as well as the nature of the OEF/OIF/OND conflict.
