Coverage of HIV pre-exposure prophylaxis (PrEP) within the active duty U.S. military, 2023.

Estimates of HIV pre-exposure prophylaxis (PrEP) coverage in the U.S. military, defined as the proportion of the persons taking HIV PrEP out of the estimated number of persons who had indications for it, have never been published. The objective of this study was to provide an estimate of HIV PrEP coverage comparable to U.S. civilian estimates. The population with indications for HIV PrEP was obtained from the Department of Defense 2018 Health Related Behaviors Survey, a stratified random sample of members of all military service branches. The military PrEP coverage estimate of 31.6% in 2023 was lower than the national U.S. estimate of 36.0% in 2022. Among the military population of men who have sex with men (MSM), an estimated 24.6% of service members had indications for PrEP, similar to the national estimate of 24.7%. MSM comprised 66% of all military service members with HIV PrEP indications, compared to 40% in the U.S. general population. The U.S. military should continue deliberate, sustained, and effective actions to address sexual health inequities among MSM, aligned and coordinated with societal efforts including improved coverage of HIV PrEP to prevent HIV transmission.
