Effects of the Criminalization of
Same-Sex Practices
 Same-sex marriage bill introduced January, 2014 further
criminalizing same-sex relationships and associations with
community groups
 Methods
 MSM recruited through respondent-driven sampling and enrolled
into a prospective cohort in Abuja from March 2013-June 2014
 Characteristics related to discrimination and HIV care are
described and compared pre-post legislation using chi-squared
statistics
 TRUST Model
 UMD/IHV HIV Prevention and Treatment Services co-located with
community group serving MSM (ICARH)
Sources: Schwartz, Nowak, Orazulike, Blattner, Charurat, Baral, TRUST Study Group (UMD, MHRP, ICARH, JHU). The immediate HIV-
related impact of enacted legislation that further criminalizes same-sex practices in Nigeria. Forthcoming
Outcomes of Criminalization on
HIV-Risks among MSM in Nigeria
 Reporting of Discrimination and Stigma
During Study Visits Pre and Post
Legislation
 Cumulative lifetime experiences of
reported fear of seeking health care
services across study visits (n=1,175
visits).

Key Themes
 Data Paradox
 There is the least amount of data characterizing the
needs of gay men and other MSM in the most
stigmatizing settings
 The world is more similar than it is different
 Where studied across the world, gay men and other
MSM have been found to have disproportionate burden
of HIV
 Highest incidence appears to be among young people
 Comprehensive Research Agenda should include
evaluating the content, scale, and implementation of
HIV prevention, treatment, and care programs for
Acknowledgements
 The gay men, other men who have sex with men
across the world who participate in these studies
given significant risks and limited personal benefits
 The community groups that make great personal and
professional sacrifices to serve the unmet health and
advocacy needs of those most marginalized in the
HIV response
 Contributions of Ideas and New Data
 Eduard Sanders, George Ayala, Adrian Smith, Sari
Reisner, Kevin Rebe, James McIntyre, Chris Beyrer,
Patrick Sullivan, Daouda Diouf, and others
