HIV Prevalence and Risk Factors Among Male Foreign Migrants in Cape Town, South Africa.

While migration has been shown to be a risk factor for HIV, variation in HIV prevalence by subgroups of migrants needs further exploration. This paper documents the HIV prevalence and key characteristics among male foreign migrants in Cape Town, South Africa and the effectiveness of respondent-driven sampling (RDS) to recruit this population. Participants in this cross-sectional study completed a behavioral risk-factor questionnaire and provided a dried blood sample for HIV analysis. Overall HIV prevalence was estimated to be 8.7 % (CI 5.4-11.8) but varied dramatically by country of origin. After adjusting for country of origin, HIV sero-positivity was positively associated with older age (p = 0.001), completing high school (p = 0.025), not having enough money for food (p = 0.036), alcohol use (p = 0.049), and engaging in transactional sex (p = 0.022). RDS was successful in recruiting foreign migrant men. A better understanding of the timing of HIV acquisition is needed to design targeted interventions for migrant men.

The Relationship Between Social Support, HIV Serostatus, and Perceived Likelihood of Being HIV Positive Among Self-Settled Female, Foreign Migrants in Cape Town, South Africa.

Female cross-border migrants experience elevated risks for HIV, and migrants in South Africa may face additional risks due to the country's underlying HIV prevalence. These risks may be mitigated by the receipt of social support. A behavioral risk-factor survey was administered using respondent-driven sampling. Multivariable regression models assessed the relationships between social support and two HIV outcomes: HIV serostatus and perceived HIV status. Low social support was not significantly associated with HIV status (aOR = 1.03, 95 % CI 0.43-2.46), but was significantly related to a perception of being HIV positive (aPR = 1.36, 95 % CI 1.04-1.78). Age, marital status, and education level were significantly associated with HIV serostatus. Illegal border-crossing, length of time in South Africa, anal sex, and transactional sex were significantly associated with aperception of being HIV positive. Future research should investigate how HIV risks and the receipt of social support change throughout the migration process.

Using respondent-driven sampling (RDS) to recruit illegal poly-substance users in Cape Town, South Africa: implications and future directions.

BACKGROUND: South Africa continues to witness an increase in illicit poly-substance use, although a precise measurement continues to be compounded by difficulties in accessing users. In a pilot attempt to use respondent-driven sampling (RDS)-a chain referral sampling method used to access populations of individuals who are 'hard-to-reach'-this article documents the feasibility of the method as recorded in a simultaneously run, multisite, poly-substance study in Cape Town. Here we aim to a) document the piloting of RDS among poly-substance users in the three socio-economic disparate communities targeted; b) briefly document the results; and c) review the utility of RDS as a research tool. METHODS: Three cross-sectional surveys using standard RDS procedures were used to recruit active poly-substance users and were concurrently deployed in three sites. Formative research was initially conducted to assess the feasibility of the survey. To determine whether RDS could be used to successfully recruit poly-substance users, social network characteristics, such as network size was determined. RESULTS: A 42.5 % coupon return rate was recorded in total from 12 initial seeds. There were vast differences in the recruitment chains of individual seeds-two generated more than 90 recruits, and 2 of the 10 recruitment chains showing a length of more than 10 waves. Findings include evidence of the use of 3 or more substances in all three sites, high levels of unemployment among users, with more than a third of participants in two sites reporting arrest for drug use in the past 12 months. CONCLUSIONS: Our results indicate that RDS was a feasible and acceptable sampling method for recruiting participants who may not otherwise be accessible. Future studies can use RDS to recruit such cohorts, and the method could form part of broader efforts to document vulnerable populations.

Effects of PREPARE, a Multi-component, School-Based HIV and Intimate Partner Violence (IPV) Prevention Programme on Adolescent Sexual Risk Behaviour and IPV: Cluster Randomised Controlled Trial.

Young South Africans, especially women, are at high risk of HIV. We evaluated the effects of PREPARE, a multi-component, school-based HIV prevention intervention to delay sexual debut, increase condom use and decrease intimate partner violence (IPV) among young adolescents. We conducted a cluster RCT among Grade eights in 42 high schools. The intervention comprised education sessions, a school health service and a school sexual violence prevention programme. Participants completed questionnaires at baseline, 6 and 12 months. Regression was undertaken to provide ORs or coefficients adjusted for clustering. Of 6244 sampled adolescents, 55.3 % participated. At 12 months there were no differences between intervention and control arms in sexual risk behaviours. Participants in the intervention arm were less likely to report IPV victimisation (35.1 vs. 40.9 %; OR 0.77, 95 % CI 0.61-0.99; t(40) = 2.14) suggesting the intervention shaped intimate partnerships into safer ones, potentially lowering the risk for HIV.

Social Support, Sexual Violence, and Transactional Sex Among Female Transnational Migrants to South Africa.

OBJECTIVES: To examine the relationship between sexual violence and transactional sex and assess the impact of social support on this relationship among female transnational migrants in Cape Town, South Africa. METHODS: In 2012 we administered a behavioral risk factor survey using respondent-driven sampling to transnational migrant women aged between 16 and 39 years, born outside South Africa, living in Cape Town, and speaking English, Shona, Swahili, Lingala, Kirundi, Kinyarwanda, French, or Somali. RESULTS: Controlling for study covariates, travel-phase sexual violence was positively associated with engagement in transactional sex (adjusted prevalence ratio [APR] = 1.38; 95% confidence interval [CI] = 1.07, 1.77), and social support was shown to be a protective factor (APR = 0.84; 95% CI = 0.75, 0.95). The interaction of experienced sexual violence during migration and social support score was APR = 0.85 (95% CI = 0.66, 1.10). In the stratified analysis, we found an increased risk of transactional sex among the low social support group (APR = 1.56; 95% CI = 1.22, 2.00). This relationship was not statistically significant among the moderate or high social support group (APR = 1.04; 95% CI = 0.58, 1.87). CONCLUSIONS: Programs designed to strengthen social support may reduce transactional sex among migrant women after they have settled in their receiving communities.

Intimate Partner Violence, Relationship Power Inequity and the Role of Sexual and Social Risk Factors in the Production of Violence among Young Women Who Have Multiple Sexual Partners in a Peri-Urban Setting in South Africa.

INTRODUCTION: This paper aims to assess the extent and correlates of intimate partner violence (IPV), explore relationship power inequity and the role of sexual and social risk factors in the production of violence among young women aged 16-24 reporting more than one partner in the past three months in a peri-urban setting in the Western Cape, South Africa. Recent estimates suggest that every six hours a woman is killed by an intimate partner in South Africa, making IPV a leading public health problem in the country. While there is mounting evidence that levels of IPV are high in peri-urban settings in South Africa, not much is known about how it manifests among women who engage in concomitantly high HIV risk behaviours such as multiple sexual partnering, transactional sex and age mixing. We know even less about how such women negotiate power and control if exposed to violence in such sexual networks. METHODS: Two hundred and fifty nine women with multiple sexual partners, residing in a predominantly Black peri-urban community in the Western Cape, South Africa, were recruited into a bio-behavioural survey using Respondent Driven Sampling (RDS). After the survey, focus group discussions and individual interviews were conducted among young women and men to understand the underlying factors informing their risk behaviours and experiences of violence. FINDINGS: 86% of the young women experienced IPV in the past 12 months. Sexual IPV was significantly correlated with sex with a man who was 5 years or older than the index female partner (OR 1.7, 95% CI 1.0-3.2) and transactional sex with most recent casual partner (OR 2.1, 95% CI 1.1-3.8). Predictably, women experienced high levels of relationship power inequity. However, they also identified areas in their controlling relationships where they shared decision making power. DISCUSSION: Levels of IPV among young women with multiple sexual partners were much higher than what is reported among women in the general population and shown to be associated with sexual risk taking. Interventions targeting IPV need to address sexual risk taking as it heightens vulnerability to violence.

Reaching the hard to reach: longitudinal investigation of adolescents' attendance at an after-school sexual and reproductive health programme in Western Cape, South Africa.

BACKGROUND: Adolescents need access to effective sexual and reproductive health (SRH) interventions, but face barriers accessing them through traditional health systems. School-based approaches might provide accessible, complementary strategies. We investigated whether a 21-session after-school SRH education programme and school health service attracted adolescents most at risk for adverse SRH outcomes and explored motivators for and barriers to attendance. METHODS: Grade 8 adolescents (average age 13 years) from 20 schools in the intervention arm of an HIV prevention cluster randomised controlled trial in the Western Cape Province of South Africa, were invited to participate in an after-school SRH program and to attend school health services. Using a longitudinal design, we surveyed participants at baseline, measured their attendance at weekly after-school sessions for 6 months and surveyed them post-intervention. We examined factors associated with attendance using bivariate and multiple logistic and Poisson regression analyses, and through thematic analysis of qualitative data. RESULTS: The intervention was fully implemented in 18 schools with 1576 trial participants. The mean attendance of the 21-session SRH programme was 8.8 sessions (S.D. 7.5) among girls and 6.9 (S.D. 7.2) among boys. School health services were visited by 17.3 % (14.9 % of boys and 18.7 % of girls). Adolescents who had their sexual debut before baseline had a lower rate of session attendance compared with those who had not (6.3 vs 8.5, p < .001). Those who had been victims of sexual violence or intimate partner violence (IPV), and who had perpetrated IPV also had lower rates of attendance. Participants were motivated by a wish to receive new knowledge, life coaching and positive attitudes towards the intervention. The unavailability of safe transport and domestic responsibilities were the most common barriers to attendance. Only two participants cited negative attitudes about the intervention as the reason they did not attend. CONCLUSIONS: Reducing structural barriers to attendance, after-school interventions are likely to reach adolescents with proven-effective SRH interventions. However, special attention is required to reach vulnerable adolescents, through offering different delivery modalities, improving the school climate, and providing support for adolescents with mental health problems and neurodevelopmental academic problems.

HIV prevalence and risk behaviours among foreign migrant women residing in Cape Town, South Africa.

HIV prevalence and risk behaviour among foreign migrants in South Africa has not been explored. This paper describes the effectiveness of respondent-driven sampling (RDS) to recruit foreign migrant women residing in Cape Town, reports HIV prevalence, and describes key characteristics among them. We conducted a biological and behavioural surveillance survey using RDS. After written informed consent, participants completed an audio computer assisted self-interview and provided a dried blood sample for HIV analysis. HIV prevalence was estimated to be 7 % (CI 4.9-9.5) among 935 women. HIV sero-positivity was associated with older age (p = 0.001), country of origin (p < 0.000), being unmarried (p < 0.000), having lived in South Africa for 3-5 years (p = 0.023), sexual debut at ≥15 years (p = 0.047), and having used a condom at last sex with a main partner (p = 0.007). Few women reported early sexual debut, or multiple sexual partners. RDS was successful in recruiting foreign migrant women.

"Money talks, bullshit walks" interrogating notions of consumption and survival sex among young women engaging in transactional sex in post-apartheid South Africa: a qualitative enquiry.

BACKGROUND: Transactional sex is believed to be a significant driver of the HIV epidemic among young women in South Africa. This sexual risk behaviour is commonly associated with age mixing, concurrency and unsafe sex. It is often described as a survival- or consumption-driven behaviour. South Africa's history of political oppression as well as the globalization-related economic policies adopted post-apartheid, are suggested as the underlying contexts within which high risk behaviours occur among Black populations. What remains unclear is how these factors combine to affect the particular ways in which transactional sex is used to negotiate life among young Black women in the country.In this paper we explore the drivers of transactional sex among young women aged 16-24, who reside in a peri-urban community in South Africa. We also interrogate prevailing constructions of the risk behaviour in the context of modernity, widespread availability of commodities, and wealth inequalities in the country. METHODS: Data were collected through 5 focus group discussions and 6 individual interviews amongst young women, men, and community members of various age groups in a township in the Western Cape, South Africa. FINDINGS: Young women engaged in transactional sex to meet various needs: some related to survival and others to consumption. In this poverty-stricken community, factors that created a high demand for transactional sex among young women included the pursuit of fashionable images, popular culture, the increased availability of commodities, widespread use of global technologies, poverty and wealth inequalities. Transactional sex encounters were characterized by sexual risk, a casual attitude towards HIV, and male dominance. However, the risk behaviour also allowed women opportunities to adopt new social roles as benefactors in sexual relationships with younger men. CONCLUSION: Transactional sex allows poor, young women to access what young people in many parts of the world also prioritize: fashionable clothing and opportunities for inclusion in popular youth culture. In the context of high HIV prevalence in South Africa, strategies are needed that present young women with safer economic gateways to create and consume alternative symbols of modernity and social inclusion.

HIV prevalence and risk behaviours from three consecutive surveys among men who have multiple female sexual partners in Cape Town.

HIV bio-behavioural surveillance surveys conducted at regular intervals are critical for monitoring of, and informing a targeted response to the HIV pandemic. We used Respondent-driven Sampling in 2006, 2008 and 2010 to recruit men who have multiple female sexual partners. We performed several logistic regression analyses to compare HIV sexual risk behaviours, and HIV infection over time. Decreases in inconsistent condom use with main partners were not sustained in 2010. Inconsistent condom use with non-main partners, partner numbers and having one-time partners continued to decrease over time. Levels of alcohol consumption in 2010 reverted to a level higher than in 2006. Non-significant increases in HIV prevalence and reporting a symptom of a sexually transmitted infection (STI) were found. The decrease in numbers of and one-time sexual partners, and in inconsistent condom use with non-main partners augers well for decreasing HIV incidence among men in the study community, but might be offset by decreases in consistent condom use with main partners, and increases in alcohol consumption and STIs.

A systematic review of behavioral interventions to prevent HIV infection and transmission among heterosexual, adult men in low-and middle-income countries.

Prevention of new HIV infections needs to move to the forefront in the fight against HIV and AIDS. In the current economic crisis, low- and middle-income countries (LMICs) should invest limited resources to amass reliable evidence-based information about behavioral prevention efforts, and on behaviors that are driving the epidemic among people who are engaging in those behaviors. This paper aims to provide a systematic review and synthesis of behavioral interventions among a group of people in high HIV-burden countries: heterosexual men in LMICs. The review includes articles published between January 2001 and May 2010 that evaluated behavioral prevention interventions among heterosexual males aged 18+ years in LMICs. The studies were evaluated using the quality assessment tool for quantitative studies developed by the Effective Public Health Practice Project. The review identified 19 articles that met the review's inclusion criteria. Most studies were conducted in South Africa (n=6); two each in Uganda and Thailand; and one in each of Angola, Brazil, Bulgaria, India, Nigeria, the Philippines, Russia, Ukraine and Zimbabwe. Eight of 19 interventions increased condom use among their respective populations. Those interventions that sought to reduce the number of sexual partners had little effect, and those that addressed alcohol consumption and intimate partner violence had mixed effects. There was no evidence for any specific format of intervention that impacted best on any of the targeted risk behaviors. The paucity of evaluated interventions for heterosexual men in LMICs suggests that adult men in these countries remain underrepresented in HIV prevention efforts.

Estimating HIV prevalence and HIV-related risk behaviors among heterosexual women who have multiple sex partners using respondent-driven sampling in a high-risk community in South Africa.

BACKGROUND: Repeated surveillance surveys are important for monitoring trends in HIV and risk behaviors over time. In countries most adversely affected by HIV and AIDS, community-level HIV biological and behavioral surveillance surveys are needed among subpopulations who engage in high-risk sexual behaviors. PURPOSE: To describe the effectiveness of respondent-driven sampling (RDS) to recruit heterosexual women who have multiple concurrent sexual partnerships, to report HIV prevalence and describe key characteristics among them, and to assess whether RDS-accessed women not usually recruited during routine sentinel surveillance surveys. METHODS: We conducted a HIV biological and behavioral surveillance surveys using RDS among women. Participants completed an audio-computer-assisted survey interview, voluntarily provided dried blood spots for HIV testing, and were offered rapid HIV testing. RESULTS: The analytical sample comprised 845 women whose mean age was 23.9 years. About 6.4% were married, 49.6% lived in informal dwellings, and 31.8% reported not to have enough money for food. HIV prevalence was 28.8% (95% confidence intervals: 24.3 to 33.4). Being between 20 and 29 years was significantly related to HIV infection. Women who had never attended a public health facility (10.1%) compared with those who had were more likely to be 16-19 years (P = 0.008), reported sexual debut at 10-14 years (P = 0.044), were more likely to have experienced a symptom of a sexually transmitted infection (P = 0.031), and to have taken illegal drugs (P = 0.007). CONCLUSIONS: RDS effectively recruited women who reported 2 or more male sexual partners in the past 3 months. HIV prevalence and HIV-related risk behaviors were high among women who have multiple concurrent partners.

Predictors of inconsistent condom use among a hard to reach population of young women with multiple sexual partners in peri-urban South Africa.

BACKGROUND: Evidence suggests that multiple concurrent sexual partnering may be a key driver of the high HIV prevalence among young women in South Africa. However, little is known about whether and to what extent women who have multiple sexual partners also engage in other high risk sexual behaviors such as inconsistent condom use. And yet, multiple concurrent sexual partnering is of little epidemiological relevance if all partners in these sexual networks use condoms consistently. This study assesses the prevalence of sexual risk behaviors and HIV, and predictors of inconsistent condom use among women aged 16-24 with multiple sexual partners in a peri-urban setting in South Africa. METHODS: We used Respondent Driven Sampling, a sampling strategy for hard-to-reach populations to recruit 259 women aged 16-24 in a bio-behavioral cross-sectional survey in the Western Cape province. Estimates of population proportions and 95% confidence intervals (CIs) were calculated using the Respondent-Driven Sampling Analysis Tool 5.6 (RDSAT). The primary outcome was inconsistent condom use in the past three months. RESULTS: Young women reported an average of 7 partners in the past 3 months and a high prevalence of sexual risk behaviors: concurrency (87%), transactional sex (91%) and age mixing (59%). Having >5 sexual partners in the last 3 months doubled the risk of unprotected sex (OR 2.43, CI 1.39-4.25). HIV prevalence was 4% among 16-19 year olds, increasing threefold (12%) at age 20-24. DISCUSSION: Multiple sexual partnering, where a high number of partners are acquired in a short space of time, is a fertile context for unprotected and risky sexual behavior. The young women featured in this survey present with a constellation of high-risk sexual behaviors that cluster to form a risk syndrome. Carefully tailored repeat bio-behavioral surveillance surveys are recommended for this sub-population.

More than just talk: the framing of transactional sex and its implications for vulnerability to HIV in Lesotho, Madagascar and South Africa.

BACKGROUND: 'Transactional sex' was regarded by the mid-1990s as an important determinant of HIV transmission, particularly in sub-Saharan Africa. Little attention has been paid to what the terms used to denote transactional sex suggest about how it is understood. This study provides a nuanced set of descriptions of the meaning of transactional sex in three settings. Furthermore, we discuss how discourses around transactional sex suggest linkages to processes of globalization and hold implications for vulnerability to HIV. METHODS: The analysis in this article is based on three case studies conducted as part of a multi-country research project that investigated linkages between economic globalization and HIV. In this analysis, we contextualize and contrast the 'talk' about transactional sex through the following research methods in three study sites: descriptions revealed through semi-structured interviews with garment workers in Lesotho; focus groups with young women and men in Antananarivo, Madagascar; and focus groups and in-depth interviews with young women and men in Mbekweni, South Africa. RESULTS: Participants' talk about transactional sex reveals two themes: (1) 'The politics of differentiation' reflects how participants used language to demarcate identities, and distance themselves from contextually-based marginalized identities; and (2) 'Gender, agency and power' describes how participants frame gendered-power within the context of transactional sex practices, and reflects on the limitations to women's power as sexual agents in these exchanges. Talk about transactional sex in our study settings supports the assertion that emerging transactional sexual practices are linked with processes of globalization tied to consumerism. CONCLUSIONS: By focusing on 'talk' about transactional sex, we locate definitions of transactional sex, and how terms used to describe transactional sex are morally framed for people within their local context. We take advantage of an opportunity to comparatively explore such talk across three different study sites, and contribute to a better understanding of both emerging sexual practices and their implications for HIV vulnerability. Our work underlines that transactional sex needs to be reflected as it is perceived: something very different from, but of at least equal concern to, formal sex work in the efforts to curb HIV transmission.

HIV risk behaviours and their relationship to intimate partner violence (IPV) among men who have multiple female sexual partners in Cape Town, South Africa.

HIV/AIDS and intimate partner violence (IPV) are growing public health concerns in South Africa. Knowledge about adult men's perpetration of IPV and links between HIV risk behaviours and IPV is limited. Respondent driven sampling was used to recruit men who have multiple concurrent female sexual partners. Forty-one percent of the 428 recruited men had perpetrated IPV. Inconsistent condom use was associated with physical IPV; experiencing a symptom of a sexually transmitted infection and engaging in transactional sex were associated with physical and sexual IPV; problem alcohol use was associated with physical, and any IPV, but not sexual IPV; having five or more partners was associated with sexual IPV; perceptions of partners' infidelity were associated with physical and any IPV. HIV risk reduction interventions among men, especially those with multiple female sex partners, should incorporate strategies to change the underlying construction of masculinity that combines the anti-social and risky behaviours of IPV perpetration, inconsistent condom use, transactional sex and heavy alcohol consumption.

"Taking care of business": alcohol as currency in transactional sexual relationships among players in Cape Town, South Africa.

In this article we examine the dynamics of social relationships in which alcohol use and risky sexual behaviors cooccur. As part of a larger biological and behavioral HIV surveillance survey, 20 men who lived in an urban, informal settlement on the outskirts of Cape Town, South Africa participated in in-depth interviews. Interview transcripts were analyzed according to a latent content analysis. Findings highlight the latent association between alcohol and transactional sex, and enable an in-depth examination of the normative role that alcohol plays in the formation of casual sexual partnerships characterized by exchange. We build on an existing conceptual model that traces the potential pathways by which alcohol use and transactional sex are linked to sexual risk behaviors. The study findings point to the need for multilevel HIV risk-reduction interventions among men to reduce excessive alcohol use, risky sexual behaviors, and underlying perceptions of ideal masculinity.

Associations between alcohol misuse and risks for HIV infection among men who have multiple female sexual partners in Cape Town, South Africa.

The occurrence of high rates of alcohol consumption in a context of high HIV prevalence in South Africa poses a significant health challenge for this country. This paper aims to answer three questions that could further our knowledge regarding the links between alcohol use and HIV infection: (a) "Are problem drinkers more likely to have multiple concurrent partners than those who are not?"; (b) "Are condoms applied less effectively and less consistently by problem drinkers compared to those who are not?"; (c) "Are the female sexual partners of problem drinkers different from those who are not?" Two cross-sectional HIV bio-behavioural surveillance surveys using Respondent-Driven Sampling were conducted in two peri-urban settings on the outskirts of Cape Town, South Africa. Eight hundred and forty-eight men aged 25-55 years who have multiple, concurrent female sexual partners were recruited. Problem drinkers had a score of ≥3 on the CAGE questionnaire. Questions enquired about partner numbers, condom use and partner traits. Multivariate logistic regression models were developed to determine significant associations between outcome variables and problem drinking. Fifty-eight percent of men were problem drinkers. Compared to non-problem drinkers, problem drinkers were significantly more likely to report having any symptom of a STI; not using condoms due to drinking; inconsistent condom use with all partner types; that their most recent once-off partner was unemployed; having met their most recent partner at an alcohol-serving venue; and having had a once-off sexual relationship. Alcohol may fuel once-off sexual encounters, often characterised by transactional sex and women's limited authority to negotiate sex and condom use; factors that can facilitate transmission of HIV. HIV prevention interventions specifically targeting drinkers, the contexts in which problem drinking occurs and multiple sexual partnering are urgently needed.

Effectiveness of respondent-driven sampling to recruit high risk heterosexual men who have multiple female sexual partners: differences in HIV prevalence and sexual risk behaviours measured at two time points.

Regular HIV bio-behavioural surveillance surveys (BBSS) among high risk heterosexual (HRH) men who have multiple female sexual partners is needed to monitor HIV prevalence and risk behaviour trends, and to improve the provision and assessment of HIV prevention strategies for this population. In 2006 and 2008 we used respondent-driven sampling to recruit HRH men and examine differences in HIV prevalence and risk behaviours between the two time points. In both surveys, the target population had little difficulty in recruiting others from their social networks that were able to sustain the chain-referral process. Key variables reached equilibrium within one to six recruitment waves and homophily indices showed neither tendencies to in-group nor out-group preferences. Between 2006 and 2008 there were significant differences in condom use with main sexual partners; numbers of sexual partners; and alcohol consumption. Further BBSS among this population are needed before more reliable trends can be inferred.

The construction of an idealised urban masculinity among men with concurrent sexual partners in a South African township.

BACKGROUND: The perspectives of heterosexual males who have large sexual networks comprising concurrent sexual partners and who engage in high-risk sexual behaviours are scarcely documented. Yet these perspectives are crucial to understanding the high HIV prevalence in South Africa where domestic violence, sexual assault and rape are alarmingly high, suggesting problematic gender dynamics. OBJECTIVE: To explore the construction of masculinities and men's perceptions of women and their sexual relationships, among men with large sexual networks and concurrent partners. DESIGN: This qualitative study was conducted in conjunction with a larger quantitative survey among men at high risk of HIV, using respondent-driven sampling to recruit participants, where long referral chains allowed us to reach far into social networks. Twenty in-depth, open-ended interviews with South African men who had multiple and concurrent sexual partners were conducted. A latent content analysis was used to explore the characteristics and dynamics of social and sexual relationships. RESULTS: We found dominant masculine ideals characterised by overt economic power and multiple sexual partners. Reasons for large concurrent sexual networks were the perception that women were too empowered, could not be trusted, and lack of control over women. Existing masculine norms encourage concurrent sexual networks, ignoring the high risk of HIV transmission. Biological explanations and determinism further reinforced strong and negative perceptions of women and female sexuality, which helped polarise men's interpretation of gender constructions. CONCLUSIONS: Our results highlight the need to address sexuality and gender dynamics among men in growing, informal urban areas where HIV prevalence is strikingly high. Traditional structures that could work as focal entry points should be explored for effective HIV prevention aimed at normative change among hard-to-reach men in high-risk urban and largely informal contexts.
