Zambia has a generalized HIV epidemic, and HIV is concentrated along transit routes. Female sex workers (FSWs) are disproportionately affected by the epidemic. HIV testing is the crucial first step for engagement in HIV care and HIV prevention activities. However, to date little work has been done with FSWs in Zambia, and little is known about barriers and facilitators to HIV testing in this population. FSW peer educators were recruited through existing sex worker organizations for participation in a trial related to HIV testing among FSWs. We conducted five focus groups with FSW peer educators (N = 40) in three transit towns in Zambia (Livingstone, Chirundu, and Kapiri Mposhi) to elicit community norms related to HIV testing. Emerging themes demonstrated barriers and facilitators to HIV testing occurring at multiple levels, including individual, social network, and structural. Stigma and discrimination, including healthcare provider stigma, were a particularly salient barrier. Improving knowledge, social support, and acknowledgment of FSWs and women's role in society emerged as facilitators to testing. Interventions to improve HIV testing among FSWs in Zambia will need to address barriers and facilitators at multiple levels to be maximally effective.

ObjectivesPartner notification (PN) following sexually transmitted disease (STI) diagnosis is a key strategy for controlling HIV/STI transmission. Anonymous partnerships are an important barrier to PN and often associated with high-risk sexual behaviour. Limited research has examined the profile of men who have sex with men (MSM) and transgender women (TW) who engage in anonymous sex. To better understand anonymous partnership practices in Lima, Peru, we assessed participant-level and partnership-level characteristics associated with anonymous sex among a sample of MSM and TW recently diagnosed with HIV/STI.MethodsMSM and TW diagnosed with HIV/STI within the past month completed a cross-sectional survey regarding anticipated PN practices. Participants reported sexual partnership types and characteristics of up to three of their most recent partners. Using a Poisson generalised estimating equation model, we assessed participant-level and partnership-level characteristics associated with anonymous partnerships.ResultsAmong 395 MSM and TW with HIV/STI, 36.0% reported at least one anonymous sexual partner in the past 3 months (mean of 8.6 anonymous partners per participant; SD 17.0). Of the 971 partnerships reported, 118 (12.2%) were anonymous and the majority (84.8%) were with male partners, followed by 11.0% with female partners and 4.2% with transgender/travesti partners. Partner-level characteristics associated with increased likelihood of having an anonymous partner included female (adjusted prevalence ratio (aPR) 2.28, 95% CI 1.05 to 4.95, p=0.04) or transgender/travesti (aPR 4.03, 95% CI 1.51 to 10.78, p=0.006) partner gender.ConclusionsBy assessing both individual-level and dyadic-level factors, these results represent an important step in understanding the complexity of partnership interactions and developing alternative PN strategies for Latin America.

Stigmatizing social environments (of which 'structural stigma' is one component) negatively affect health-related outcomes. However, few studies have examined structural stigma related to sexual minority status as a risk factor for HIV outcomes among MSM.In August 2013, members of a large MSM social and sexual networking site in the United States completed a survey about HIV-prevention practices. A previously validated composite index provided values for state-level structural stigma, including density of same-sex couples, proportion of public high schools with Gay-Straight Alliances, state laws protecting sexual minorities, and public opinion toward homosexuality. Multivariable logistic generalized estimating equations assessed the relationship between structural stigma and condomless anal intercourse, use and awareness of antiretroviral-based HIV-prevention strategies (i.e. pre and postexposure prophylaxis, or PEP and PrEP), and comfort discussing male-male sex with primary care providers.Among the 4098 HIV-uninfected MSM, lower state-level structural stigma was associated with decreased odds of condomless anal intercourse [adjusted odds ratio (aOR) 0.97 per one unit increase in structural stigma score, 95% confidence interval (CI) 0.94-0.99], increased odds of awareness of PEP (aOR 1.06, 95% CI 1.02-1.09), and PrEP (aOR 1.06, 95% CI 1.02-1.10), having taken PEP (aOR 1.15, 95% CI 1.05-1.26) and PrEP (aOR 1.21, 95% CI 1.01-1.44), and comfort discussing male-male sex with providers (aOR 1.08, 95% CI 1.05-1.11), after adjusting for social and state-level confounders.MSM living in more stigmatizing environments had decreased use of antiretroviral-based HIV-prevention strategies compared to those in less stigmatizing environments. Legal reforms protecting sexual minorities should be evaluated as structural interventions that could reduce HIV risk among MSM.

We assessed the potential impact of Internet partner notification among men who have sex with men and transgender women in Peru recently diagnosed as having sexually transmitted disease. Use of Internet partner notification was anticipated for 55.9% of recent partners, including 43.0% of partners not currently expected to be notified, a 20.6% increase in anticipated notification outcomes.
