Study looks at risk factors for HIV in US Navy and Marines during 'Don't Ask, Don't Tell'

"[M]ale-to-male sexual contact was a much more common mode of infection than previously reported," reports the new study, led by Shilpa Hakre, DrPH, MPH, of the US Military HIV Research Program, Rockville, Md. The researchers add, "Several opportunities for primary prevention messaging now possible after DADT repeal are evident."

What Factors Affected HIV Risk Under 'Don't Ask, Don't Tell'?

The survey study included 250 U.S. Navy and Marines personnel newly diagnosed as HIV positive from 2005 to 2010—while DADT was in place. "Don't Ask, Don't Tell" was repealed in 2011, ending the ban on openly homosexual individuals serving in the U.S. Armed Forces.

Participants in the anonymous online survey were asked about their sexual behaviors and other potential risk factors in the three years before acquiring HIV infection. The subjects were identified through the Navy Bloodborne Infection Management Center, which is responsible for HIV screening, prevention, care, and management. Sixty-four HIV-infected Sailors and Marines responded to the survey.

The most frequent risk factor was same-sex contact, reported by 84 percent of respondents. Fifty-five percent said they only had sex with men during the three-year period before they became infected. During this time, about half had concurrent relationships with different partners during this time. Sex with non-service members appeared to be another risk factor for HIV.

Most of the HIV-infected personnel reported using condoms rarely or inconsistently, especially for anal sex. Other risky sexual behaviors were common as well, such as meeting "new, casual, or temporary" partners at bars or clubs or on the Internet. Alcohol use appeared to contribute to risky behaviors.

"More than three-quarters of respondents were surprised at their HIV test result," Dr Hakre and coauthors write. Many reported low condom use because they knew or trusted their partner and their partner's HIV status. The findings suggest that the infected Sailors and Marines underestimated their individual risk of acquiring HIV

In the Navy and Marines as in the civilian population, men who have sex with men account for most new cases of HIV infection. The new survey finds a higher rate of male-to-male sexual contact than in previous military studies—possibly reflecting "liberalized responses due to DADT repeal effects," the researchers write. In the past, some military personnel with sexually transmitted infections have sought care in the civilian community, for fear of being discharged if their sexual orientation is revealed while receiving care at military health facilities.

The findings help to clarify the risk factors for HIV Armed Forces personnel, and highlight opportunities for prevention efforts—particularly promoting condom use. Now that "Don't Ask, Don't Tell" is no longer in force, prevention efforts for military personnel may be more targeted more openly and effectively, Dr Hakre and coauthors believe. They conclude, "DADT repeal may afford opportunities for facilitating necessary primary HIV prevention strategies such as those targeting condom use and newer social outlets such as Internet networking."
