The United States (US) Army
implemented a comprehensive HIV characterization program in 2012 following
repeal of the Don't Ask, Don't Tell policy banning openly homosexual
individuals from serving in the US military. Program staff administered a
standardized case report form to soldiers newly diagnosed with HIV from 2012 to
2014 in compliance with new program requirements. The case report form
documented sociodemographic, sexual, and other risk behavior information
elicited from US Army regulation-mandated epidemiologic interviews at initial
HIV notification. A majority of HIV-infected soldiers were male and of
black/African American racial origin. In the HIV risk period, male soldiers
commonly reported male–male sexual contact, civilian partners, online partner-seeking,
unprotected anal sex, and expressed surprise at having a positive HIV result.
Don't Ask, Don't Tell repeal allows for risk screening and reduction
interventions targeting a newly identifiable risk category in the US Army.
At-risk populations need to be identified and assessed for possible unmet
health needs.
… These findings
mirror a description of the HIV epidemic in the United States; in 2010, 63% of
all new HIV infections and 78% of new HIV infections among men were
attributable to male–male sexual contact, whereas 44% of all new HIV infections
were among blacks/African Americans.1 Both groups constitute a minority of
the US population: Purcell et al11 estimated
that 3.5%–4.4% of the adult male US population were MSM, which represented
approximately 2% of the 2008 US population; Blacks/African Americans formed 13.6%
of the 2010 US population. Although it is unknown what proportion of the active
US Army engage in male–male sexual contact, in fiscal year 2012 black/African
Americans were one of the minority race and ethnic groups in the US Army
comprising 20% of soldiers on active service, whereas soldiers of white,
non-Hispanic race and ethnic origin made up 61% of the active US Army.12
Several factors that increase HIV acquisition and
transmission reportedly explain the racial disparity in HIV infection status in
the general population. Structural factors such as social and income
inequalities and lack of economic opportunity were correlated significantly
with a higher HIV risk among blacks/African Americans.2 Black/African American MSM are more
likely to have sexual partners of unknown HIV status13,14 and
perceive their risk of HIV acquisition to be lower with intraracial sexual
partners.13 Linkage
to care within 3 months of HIV diagnoses and antiretroviral therapy use, both
effective risk-reduction interventions among persons positive for HIV, were
less prevalent among black/African American MSM.13,15 Reductions
in community viral load levels from large-scale antiretroviral therapy use have
been associated with a decrease in new HIV diagnoses.16 Despite
universal health care and periodic HIV testing, racial and risk disparities
persist in the US Army and seem to be influenced by drivers of the national HIV
epidemic among black/African American MSM.
One in 2 soldiers had a negative HIV result within
a year of diagnosis. Among MSM, 1 in 2 had an HIV test outside the MHS.
Although service-related reasons predominated, risk-based reasons for HIV
testing were frequent, especially among MSM. Almost all syphilis infections
were reported by MSM and not MSW. Together, these findings indicate that soldiers
at high risk for HIV and STIs may need more frequent testing, and more
services, such as provision of PrEP, targeted to their health needs. National
guidelines recommend that sexually active MSM get annual screening for HIV,
syphilis, chlamydia, and gonorrhea, and MSM with multiple or anonymous sexual
partners get quarterly or biannual screening.17 Testing
more frequently provides an opportunity for earlier access to treatment, and
utilization of services such as behavior counseling, thus reducing onward
transmission risks. As a means of HIV prevention, national clinical practice
guidelines recommend health care providers consider offering PrEP to eligible patients,
including MSM, exceeding a threshold risk score.18
MSM commonly described having nonservice members,
casual partners, or strangers (versus service members or a spouse or main
partner) as sexual partners in their period at risk. They frequently met these
temporary partners (37%) on the Internet rather than bars/clubs or other
venues. Furthermore, among those who reported a location where they likely
acquired HIV, most of them believed that the exposure occurred in southern US
states, which is consistent with the epidemiology of HIV in the United States.
Although the prevalence of HIV was highest in northeastern United States and
the rate of new HIV diagnoses decreased from 2008 to 2011 in all regions except
the Midwest, the southern United States continued to have the highest rate of
diagnoses among all regions in the United States.19 Seeking partners on the Internet and
higher sexual risk behavior associated with online partner seeking have been
reported among HIV-infected MSM. A meta-analysis conducted in 2006 found that
among MSM recruited offline, online partner-seeking was more prevalent among
HIV-infected MSM (49.6%) than uninfected MSM (41.2%).20 In a
meta-analysis conducted in 2014, unprotected anal intercourse was common among
MSM who sought partners on the Internet (versus those who did not) especially
among HIV-infected MSM irrespective of the HIV serostatus of their partners.21 Risk
reduction interventions among people living with HIV have reduced secondary
transmission risk. In 2 large intervention trials conducted at 20 US-based
clinics, a significant reduction in unprotected vaginal or anal intercourse was
seen among HIV positive participants who received counseling from medical
providers compared with those who received standard care.22,23 These
risk reduction programs may reduce HIV transmission and acquisition risks in
the US Army.
Consistent with the US HIV epidemic, men who had
male–male sexual contact and of black/African-American racial origin comprised
a majority of active-duty soldiers who acquired HIV in the US Army.
HIV-infected soldiers frequently reported nonservice member partners, online
partner-seeking, unprotected anal intercourse, surprise at testing HIV
positive, and seeking HIV or STI testing outside the MHS. Prevention programs
ascertaining the needs of and targeting MSM and other populations at high risk
are now possible after DADT repeal. Adopting and adapting best practices in the
civilian community for HIV prevention and risk reduction to the US Army should
be a priority.
