Introduction
Men who have sex with men (MSM) are disproportionately afected
by the human immunodefciency virus (HIV) compared to the general
population in nearly all countries reliably collecting surveillance data
[1,2]. MSM have 19.3-fold greater odds of being infected with HIV
compared with the general population in low- and middle-income
country settings [3]. Te prevalence of HIV among MSM across regions
(North, South, and Central America; South and Southeast Asia; and
Sub-Saharan Africa) ranges consistently between 14 and 18% [1]. In
many high-income countries, the incidence of HIV among MSM
remains unchanged over recent years, and in some cases, it is increasing
even when HIV incidence in the general population is in decline [4].
For example, in the United States, the number of new HIV infections
among MSM has been increasing at a rate of 8% per year since 2001 [5].
Te health and prevention benefts of antiretroviral therapy
(ART) in the management of HIV are now well documented [6-10].
Behavioral prevention programs, early diagnosis, prompt linkage to
sustained care, retention in care, receipt of ART, and viral suppression
constitute points along a comprehensive continuum of HIV care [11].
Te efective implementation of a comprehensive continuum of care,
including unfettered access to and utilization of ART, is associated
with reduced morbidity, reduced mortality, and reduced onward
transmission of HIV [12-14]. However, current service delivery models
are less than optimal in linking and retaining socially marginalized
groups, resulting in drop-ofs in the treatment cascade and failure to
fully realize the health and prevention benefts of ART [15,16]. Tese
gaps are particularly true for MSM as evidenced by persistently high
HIV prevalence and incidence rates. For MSM, HIV responses at the
country level continue to be seriously hampered by daily experiences
of stigma, discrimination, violence and criminalization [17-20]. MSM
who live in countries that criminalize homosexuality have higher mean
scores on perceived homophobia scales and decreased access to basic
HIV services, including access to ART, compared to MSM who live in
countries with more supportive legal frameworks [21].
Abstract
Objectives: The health and prevention benefts of antiretroviral therapies (ART), delivered as part of comprehensive
HIV care programs remain unrealized for men who have sex with men (MSM). This multilevel study explores the
correlates of drop-off from the HIV care continuum in an international study of MSM, taking into account individual and
regional differences in access to and utilization of care.
Methods: We conducted a study of the continuum of HIV diagnosis and care among 6095 MSM using data
collected from an international online survey of MSM conducted in 2012. In this model of the HIV treatment cascade,
we treated each point along the continuum as an outcome variable. We then investigated the relationships between
clinical care outcomes and a set of demographic and psychosocial factors that were hypothesized to correlate with the
outcomes using bivariate and multivariable statistical techniques.
Results: Among MSM living with HIV for longer than 12 months (n=632), 50%(n=319) were virologically
suppressed. Among MSM recently infected with HIV (n=91), the proportion was relatively smaller at 33%. Signifcant
correlates of being on ART and retained in care included: accessibility of HIV treatment; comfort with a healthcare
provider; and engagement in a gay community. Perceptions of homophobia were negatively associated with being on
ART and being retained in care.
Conclusions: These fndings underscore the need for service delivery models that sensitively address HIV among
MSM. Public health offcials should adopt comprehensive HIV programs that include mutually reinforcing components
and that address varying needs of MSM newly diagnosed and living with HIV. Comprehensive HIV programs must also
support the critical role communities play in linking and retaining MSM into HIV services. Further studies validating the
fndings in country-specifc contexts are warranted.
