NYU Study Suggests Health and Social Inequities may Drive HIV Infection in Young Men Who Have Sex with Men
May 19, 2015 - HIV infections continue to rise in a new generation of young, gay, bisexual and other men who have sex with men (YMSM) despite three decades of HIV prevention as well as recent availability of
biomedical technologies to prevent infection. In the U.S., it is estimated that 63% of incident HIV
infections in 2010 were among YMSM despite the fact that they represent a very small portion of
the population. Given this heightened risk for HIV seroconversion among YMSM,
researchers at New York University's Center for Health, Identity, Behavior &
Prevention Studies (CHIBPS) sought to identify the factors associated with
incident HIV infection among a cohort of racially/ethnically and socioeconomically diverse YMSM.
Their paper, “Incidence of HIV infection in Young Gay, Bisexual, and other YMSM: The P18 Cohort
Study,” published in the Journal of Acquired Immune Deficiency Syndromes ( JAIDS ), reports on data
collected from 600 YMSM between the ages of 18 and 19 enrolled in the P18 Cohort. These
participants were followed over a three-year period and received HIV testing and
counseling as part of the study.
Over the study period, the cumulative incidence of HIV was 7.2% and HIV seroconversion was associated
with perceived SES and race/ethnicity. HIV seroconversions were lower among White YMSM, compared with
their Black and Hispanic/Latino counterparts. Also, HIV seroconversions were more likely
among those who self-reported a perceived lower and middle/average SES (49% and 40%,
respectively), compared to those who reported a higher perceived SES (12%).
"The data from our P18 Cohort Study demonstrate the social and structural inequities that continue
to drive racial/ethnic disparities in HIV infections,” said Perry N. Halkitis and Farzana Kapadia,
the study investigators. “Assumptions about differences in sexual behavior along racial lines are
fueling stereotypes and these stereotypes are detrimental to prevention efforts. We find that
young Black men are not engaging in more sexual activity but experience more structural
and social inequities than their White peers."
“In fact, our study findings show that socioeconomic status (SES) is key driver of HIV seroconversion;
individuals who reported a lower perceived SES were more likely to seroconvert over the course of the
study period. Moreover, in our cohort study, Black YMSM were more likely to be of lower SES and were
also more likely to seroconvert," said Halkitis and Kapadia.
The confluence of these factors is particularly problematic as low SES individuals are more likely
to reside in neighborhoods with higher levels of poverty, environments associated with lower access
to effective health services, and higher level of untreated sexually transmitted infections (STIs)
including HIV, conditions which have been shown to be inextricably connected to each other and
also linked to increased risk for HIV acquisition and transmission. In the study residing in
a high HIV prevalence neighborhood was associated with seroconversion.
In addition, younger average age at sexual debut with another man was also associated with a greater
likelihood of HIV seroconversion. Specifically, YMSM who initiated sex with another man at or after
the age of 14 were substantially less likely to seroconvert. This suggests that access to
comprehensive sexual education programs that include components on sexuality education
are warranted to bolster HIV prevention programming among adolescent and emerging adult YMSM.
“Taken together, these findings provide further evidence for the existence of significant
racial/ethnic and SES related disparities in HIV incidence among YMSM. In addition,
these findings suggest that for sexual minority men, effective HIV prevention
programs will need to attend to not only behavioral factors, such as age of
sexual debut, but also structural and social conditions that continue to
place this new generation of YMSM at heightened risk for acquiring HIV,” said Halkitis and Kapadia.
Future studies are needed to understand the relative contributions of economic, psychosocial, and
structural factors that perpetuate racial/ethnic disparities in HIV incidence. Such
information will aid in the strategic scale-up of existing interventions and the development
of new ones aimed at addressing these inequities at multiple levels.
