Same‐sex practices and orientation are both stigmatized and criminalized in many countries across sub‐Saharan Africa. This study aimed to assess the relationship of fear of seeking healthcare and disclosure of same‐sex practices among a sample of men who have sex with men (MSM) in Swaziland with demographic, socio‐economic and behavioural determinants.

Social capital is important to disadvantaged groups, such as sex workers, as a means of facilitating internal group-related mutual aid and support as well as access to broader social and material resources. Studies among sex workers have linked higher social capital with protective HIV-related behaviors; however, few studies have examined social capital among sex workers in sub-Saharan Africa. This cross-sectional study examined relationships between two key social capital constructs, social cohesion among sex workers and social participation of sex workers in the larger community, and HIV-related risk in Swaziland using respondent-driven sampling. Relationships between social cohesion, social participation, and HIV-related risk factors were assessed using logistic regression. HIV prevalence among the sample was 70.4% (223/317). Social cohesion was associated with consistent condom use in the past week (adjusted odds ratio [AOR] = 2.25, 95% confidence interval [CI]: 1.30–3.90) and was associated with fewer reports of social discrimination, including denial of police protection. Social participation was associated with HIV testing (AOR = 2.39, 95% CI: 1.36–4.03) and using condoms with non-paying partners (AOR = 1.99, 95% CI: 1.13–3.51), and was inversely associated with reported verbal or physical harassment as a result of selling sex (AOR = 0.55, 95% CI: 0.33–0.91). Both social capital constructs were significantly associated with collective action, which involved participating in meetings to promote sex worker rights or attending HIV-related meetings/ talks with other sex workers. Social- and structural-level interventions focused on building social cohesion and social participation among sex workers could provide significant protection from HIV infection for female sex workers in Swaziland.

Similar to other Southern African countries, Swaziland has been severely affected by HIV, with over a quarter of its reproductive‐age adults estimated to be living with the virus, equating to an estimate of 170,000 people living with HIV. The last several years have witnessed an increase in the understanding of the potential vulnerabilities among men who have sex with men (MSM) in neighbouring countries with similarly widespread HIV epidemics. To date, there are no data characterizing the burden of HIV and the HIV prevention, treatment and care needs of MSM in Swaziland.

Research emphasising the importance of parenting behaviours and aspirations for child outcomes has been seized on by policymakers to suggest the responsibility of the worst off themselves for low levels of social mobility. This article provides a critique of the way in which research evidence has been used to support the dominant policy discourse in this area, as well as an empirical analysis. We use the Millennium Cohort Study to interrogate the relationship between social class and attainment in the early years of schooling. We investigate the extent to which social class inequalities in early cognitive scores can be accounted for by parental education, income, family social resources and parental behaviours. We conclude that social class remains an important concept for both researchers and policymakers, and that the link between structural inequalities and inequalities in children’s cognitive scores cannot be readily accounted for in terms of individual parenting behaviours.

Background:Female sex workers (FSWs) are vulnerable to violence within and beyond the workplace. Violence is associated with increased burden of HIV, possibly explained through physiologic or behavioral causal pathways. These analyses sought to determine the relationship between lifetime sexual violence with unprotected, condomless vaginal intercourse (UVI) among FSWs in West Africa. Methods:FSWs (aged ≥18 years) were recruited into a cross-sectional study through respondent-driven sampling in two West African countries, Togo and Burkina Faso. A total of 1380 participants were enrolled from January to July 2013, and completed a sociobehavioral questionnaire and HIV testing. Measures included sex work history, lifetime experiences of violence victimization, sexual practices, and UVI (past month). Crude and adjusted robust log binomial regression was conducted to estimate prevalence ratios (PrR) as a measure of association between UVI with clients and the primary exposure, forced sex. Results:Self-reported lifetime physical abuse (47.3%), forced sex (33.0%), and any violence (57.9%) were common. Almost one-quarter (23.9%) reported recent UVI with clients. History of forced sex was independently associated with recent UVI with clients [vs. none, adjusted PrR: 1.49; 95% confidence interval (CI): 1.18 to 1.88], with evidence of partial mediation by difficult condom negotiation with regular (aPrR: 1.83; 95% CI: 1.43 to 2.34) and new clients (aPrR: 1.60; 95% CI: 1.13 to 2.29). Discussion:These data demonstrate the significant relationship between sexual violence experienced by FSWs and unprotected sex with clients. Comprehensive interventions reducing vulnerabilities to violence combined with improved condom negotiation are needed to address the complex influences of condom use during sex work as a means of ultimately lowering HIV acquisition and transmission.

There are limited data characterizing the burden of HIV among men who have sex with men (MSM) in Malawi. Epidemiologic research and access to HIV prevention, treatment and care services have been traditionally limited in Malawi by criminalization and stigmatization of same‐sex practices. To inform the development of a comprehensive HIV prevention intervention for Malawian MSM, we conducted a community‐led assessment of HIV prevalence and correlates of infection.

Social stigma is common among men who have sex with men (MSM) across Sub-Saharan Africa, and may influence risks for HIV and sexually transmitted infections (STIs) via its association with depression. We conducted a cross-sectional study of 530 MSM in Lesotho accrued via respondent-driven sampling. Using generalized structural equation models we examined associations between stigma, social capital, and depression with condom use and testing positive for HIV/STIs. Depression was positively associated with social stigma experienced or perceived as a result of being MSM. In contrast, increasing levels of social cohesion were negatively associated with depression. Social stigma was associated with testing positive for HIV; however, this association did not appear to be mediated by depression or condom use. These data suggest a need for integrated HIV and mental health care that addresses stigma and discrimination and facilitates positive social support for MSM.

Introduction:The TRUST model based on experimental and observational data posits that integration of HIV prevention and universal coverage of antiretroviral treatment at a trusted community venue provides a framework for achieving effective reduction in HIV-related morbidity and mortality among men who have sex with men (MSM) living with HIV, as well as reducing HIV incidence. The analyses presented here evaluate the utility of respondent-driven sampling as an implementation tool for engaging MSM in the TRUST intervention. Methods:The TRUST integrated prevention and treatment model was established at a trusted community center serving MSM in Abuja, Nigeria. Five seeds have resulted in 3–26 waves of accrual between March 2013 and August 2014, with results presented here characterizing HIV burden and engagement in HIV care for 722 men across study recruitment waves. For analytic purposes, the waves were collapsed into 5 groups: 4 equally spaced (0–4, 5–9, 10–14, and 15–19) and 1 ranging from the 20th to the 26th wave with significance assessed using Pearson &khgr;2 test. Results:In earlier waves, MSM were more likely to have reported testing for HIV (82.9% in waves 0–4, 47.7% in waves 20–26; P < 0.01). In addition, biologically confirmed HIV prevalence decreased from an average of 59.1% to 42.9% (P < 0.05) in later waves. In earlier waves, about 80% of participants correctly reported their HIV status as compared with less than 25% in the later waves (P < 0.01). Finally, participants reporting being on ART decreased from 50% to 22.2% in later waves (P < 0.01). Conclusions:Implementation science studies focused on demonstrating impact of universal HIV treatment programs among people living with HIV necessitate different accrual methods than those focused on preventing HIV acquisition. Here, respondent-driven sampling was shown to be an efficient method for reaching marginalized populations of MSM living with HIV in Nigeria, and engaging them in universal HIV treatment services.

In 1994, South Africa approved a constitution providing freedom from discrimination based on sexual orientation. Other Southern African countries, including Botswana, Malawi, and Namibia, criminalize same-sex behavior. Men who have sex with men (MSM) have been shown to experience high levels of stigma and discrimination, increasing their vulnerability to negative health and other outcomes. This paper examines the relationship between criminalization of same-sex behavior and experiences of human rights abuses by MSM. It compares the extent to which MSM in peri-urban Cape Town experience human rights abuses with that of MSM in Gaborone, Botswana; Blantyre and Lilongwe, Malawi; and Windhoek, Namibia. In 2008, 737 MSM participated in a cross-sectional study using a structured survey collecting data regarding demographics, human rights, HIV status, and risk behavior. Participants accrued in each site were compared using bivariate and multivariate logistic regression. Encouragingly, the results indicate MSM in Cape Town were more likely to disclose their sexual orientation to family or healthcare workers and less likely to be blackmailed or feel afraid in their communities than MSM in Botswana, Malawi, or Namibia. However, South African MSM were not statistically significantly less likely experience a human rights abuse than their peers in cities in other study countries, showing that while legal protections may reduce experiences of certain abuses, legislative changes alone are insufficient for protecting MSM. A comprehensive approach with interventions at multiple levels in multiple sectors is needed to create the legal and social change necessary to address attitudes, discrimination, and violence affecting MSM.

Transgender women are at high risk for the acquisition and transmission of HIV. However, there are limited empiric data characterizing HIV‐related risks among transgender women in sub‐Saharan Africa. The objective of these analyses is to determine what factors, including sexual behaviour stigma, condom use and engagement in sex work, contribute to risk for HIV infection among transgender women across three West African nations.
