Factors associated with HIV sero-positivity in young, rural South African men

Which groups are most affected by sexual violence? A disaggregated analysis by sex, age, and HIV-status of adolescents living in South Africa

BACKGROUND

Estimates on sexual violence (SV) among adolescents are rarely disaggregated by key indicators.

OBJECTIVE

We examine the independent effects of sex, age, HIV status and mode of HIV acquisition on the exposure to SV using generalised estimating equations models and proportional hazard model.

PARTICIPANT AND SETTING

Data from a 4-year prospective cohort study of 1447 adolescents (ages 10-19, 57% girls, 76% living with HIV) in South Africa.

METHODS

We describe the lifetime prevalence of three forms of SV: non-contact (unwanted showing of private parts), contact (coerced sexual debut, attempted and completed forced penetrative or oral sex,) and exploitative (sex in exchange for goods/money).

RESULTS

Overall, 23.9% (95%CI = 21.7%-26.1%) reported exposure to SV at some point in their lives: non-contact = 5.7%, contact = 9.0% and exploitative = 15.8%. While girls reported higher rates of exploitative (18.4% vs 12.3%; p < 0.001) and contact SV (12.3% vs 4.6%; p < 0.001), there were no differences in levels of non-contact SV by sex (6.5% vs 4.6%; p = 0.086). Exposure to any SV doubled in late adolescence (10-14 years = 7.0% vs ≥15 years = 31.7%; aIRR = 2.07; 95%CI = 1.82-2.37). Though level of SV were comparable between those living with HIV and those HIV-uninfected (22.9% vs 26.2%; p = 0.182), adolescents who recently acquired HIV were twice as likely to experience SV compared to adolescents who perinatally acquired HIV (42.3% vs 15.7%; aIRR = 2.03; 95%CI = 1.73-2.39). This association persisted when analysis was restricted to incidence SV during follow-up (aIRR = 1.53; 95%CI = 1.23-2.10).

CONCLUSION

Exposure to SV was high for both sexes, increased with age and more prevalent among adolescents who recently acquired HIV. SV prevention and response services must also be offered to boys and strengthened in HIV care services.

Negotiating sexual and gender diversity in rural and peri-urban KwaZulu-Natal, South Africa

A noticeable tendency in the first generation of scholarship on sexual orientation and gender identity/expression (SOGIE) in Africa has been the focus on urban or modern institutional settings. A dominant theme is to document people's struggles against stigma, fear and violence to better inform interventions to strengthen human rights and sexual health for all. In some cases, unintentionally, the impression conveyed of Africa is of a continent with cultures that are uniformly, hostile to SOGIE rights. The present study arises from a large survey among boys and men in KwaZulu-Natal, South Africa that problematises that impression. The study revealed unexpectedly high levels of same-sex sexual experience among boys and men in a mostly rural, culturally conservative setting. Following from that revelation, we conducted in-depth interviews to gain insight into their lives. Informants did indeed recount many incidents of discrimination and violence and admitted to sometimes severe emotional health problems. Yet they also spoke of finding love, acceptance, allies, resources, humour and hope for the future. In this paper, we tease out key themes from the interviews in relation to trends in the scholarship.

Estimating the contribution of key populations towards HIV transmission in South Africa

INTRODUCTION

In generalized epidemic settings, there is insufficient understanding of how the unmet HIV prevention and treatment needs of key populations (KPs), such as female sex workers (FSWs) and men who have sex with men (MSM), contribute to HIV transmission. In such settings, it is typically assumed that HIV transmission is driven by the general population. We estimated the contribution of commercial sex, sex between men, and other heterosexual partnerships to HIV transmission in South Africa (SA).

METHODS

We developed the "Key-Pop Model"; a dynamic transmission model of HIV among FSWs, their clients, MSM, and the broader population in SA. The model was parameterized and calibrated using demographic, behavioural and epidemiological data from national household surveys and KP surveys. We estimated the contribution of commercial sex, sex between men and sex among heterosexual partnerships of different sub-groups to HIV transmission over 2010 to 2019. We also estimated the efficiency (HIV infections averted per person-year of intervention) and prevented fraction (% IA) over 10-years from scaling-up ART (to 81% coverage) in different sub-populations from 2020.

RESULTS

Sex between FSWs and their paying clients, and between clients with their non-paying partners contributed 6.9% (95% credibility interval 4.5% to 9.3%) and 41.9% (35.1% to 53.2%) of new HIV infections in SA over 2010 to 2019 respectively. Sex between low-risk groups contributed 59.7% (47.6% to 68.5%), sex between men contributed 5.3% (2.3% to 14.1%) and sex between MSM and their female partners contributed 3.7% (1.6% to 9.8%). Going forward, the largest population-level impact on HIV transmission can be achieved from scaling up ART to clients of FSWs (% IA = 18.2% (14.0% to 24.4%) or low-risk individuals (% IA = 20.6% (14.7 to 27.5) over 2020 to 2030), with ART scale-up among KPs being most efficient.

CONCLUSIONS

Clients of FSWs play a fundamental role in HIV transmission in SA. Addressing the HIV prevention and treatment needs of KPs in generalized HIV epidemics is central to a comprehensive HIV response.

Factors associated with HIV in younger and older adult men in South Africa: findings from a cross-sectional survey

OBJECTIVE

This study investigated the behavioural, psychosocial and biological factors associated with HIV in a younger group of men (15 to 24 years) compared with an older group of men (25 to 35 years).

DESIGN

A household-based, cross-sectional study was conducted.

SETTING

Men were randomly selected using a two-stage random sampling method in KwaZulu-Natal, South Africa, between June 2014 and June 2015.

PARTICIPANTS

Overall, we interviewed 1472 younger men and 1138 older men. Only participants who could speak English or Zulu, were able to provide informed consent and who were expected to be living in the study area for the next 12 months were enrolled into the study.

PRIMARY AND SECONDARY OUTCOMES

HIV status was the primary outcome for the study. Men's HIV status was derived from blood samples collected in the study which were tested for HIV antibodies.

RESULTS

HIV prevalence was higher among older men (35.4%, 95% CI: 31.7 to 39.1) than younger men (7.6%, 95% CI: 6.2 to 9.4, p<0.01). Older men, who completed secondary school had a lower likelihood of being HIV positive (adjusted OR (AOR): 0.41, 95% CI: 0.27 to 0.63, p<0.001) and those with greater food insecurity had a higher likelihood of being HIV positive (AOR: 1.57, 95% CI: 1.05 to 2.34, p=0.04). Younger men with a higher number of lifetime sexual partners had a higher likelihood of being HIV positive (AOR: 1.04, 95% CI: 0.99 to 1.09, p=0.09).

CONCLUSION

Given that the HIV prevalence is higher in the older men, community based interventions need to target older men for medical circumcision and support HIV positive men to improve their material conditions early. For younger men intervening to reduce HIV risk behaviours at a young age before these behaviours become entrenched should be central to HIV prevention programmes.

The Role of Gender in Patient-Provider Relationships: A Qualitative Analysis of HIV Care Providers in Western Kenya with Implications for Retention in Care

The disproportionate burden of HIV among women in sub-Saharan Africa reflects underlying gender inequities, which also impact patient-provider relationships, a key component to retention in HIV care. This study explored how gender shaped the patient-provider relationship and consequently, retention in HIV care in western Kenya. We recruited and consented 60 HIV care providers from three facilities in western Kenya affiliated with the Academic Model Providing Access to Healthcare (AMPATH). Trained research assistants conducted and audio recorded 1-h interviews in English or Swahili. Data were transcribed and analyzed in NVivo using inductive thematic analysis. Gender constructs, as culturally defined, emerged as an important barrier negatively impacting the patient-provider relationship through three main domains: (1) challenges establishing clear roles and sharing power due to conflicting gender versus patient/provider identities, (2) provider frustration over suboptimal patient adherence resulting from gender-influenced contextual barriers, and (3) negative provider perceptions shaped by differing male and female approaches to communication. Programmatic components addressing gender inequities in the health care setting are urgently needed to effectively leverage the patient-provider relationship and fully promote long-term adherence and retention in HIV care.

Health Risk Behaviour among Adolescents Living with HIV in Sub-Saharan Africa: A Systematic Review and Meta-Analysis

The burden of health risk behaviour (HRB) among adolescents living with HIV (ALWHIV) in sub-Saharan Africa (SSA) is currently unknown. A systematic search for publications on HRB among ALWHIV in SSA was conducted in PubMed, Embase, PsycINFO, and Applied Social Sciences Index and Abstracts databases. Results were summarized following PRISMA guidelines for systematic reviews and meta-analyses. Heterogeneity was assessed by the DerSimonian and Laird method and the pooled estimates were computed. Prevalence of current condom nonuse behaviour was at 59.8% (95% CI: 47.9–71.3%), risky sexual partnerships at 32.9% (95% CI: 15.4–53.2%), transactional sex at 20.1% (95% CI: 9.2–33.8%), and the experience of sexual violence at 21.4% (95% CI: 16.3–27.0%) among ALWHIV. From this meta-analysis, we did not find statistically significant differences in pooled estimates of HRB prevalence between ALWHIV and HIV uninfected adolescents. However, there was mixed evidence on the occurrence of alcohol and drug use behaviour. Overall, we found that research on HRB among ALWHIV tends to focus on behaviour specific to sexual risk. With such a high burden of HRB for the individuals as well as society, these findings highlight an unmet need for age-appropriate interventions to address the behavioural needs of these adolescents.

Transactional sex and risk for HIV infection in sub-Saharan Africa: a systematic review and meta-analysis

Introduction

Young women aged 15 to 24 years in sub-Saharan Africa continue to be disproportionately affected by HIV. A growing number of studies have suggested that the practice of transactional sex may in part explain women's heightened risk, but evidence on the association between transactional sex and HIV has not yet been synthesized. We set out to systematically review studies that assess the relationship between transactional sex and HIV among men and women in sub-Saharan Africa and to summarize the findings through a meta-analysis.

Methods

The search strategy included 8 databases, hand searches in 10 journals, and searches across 17 websites and portals for organizations as informed by expert colleagues. A systematic review of cross-sectional and longitudinal studies was carried out for studies on women and men who engage in transactional sex published up through 2014. Random effects meta-analysis was used to further examine the relationship between transactional sex and prevalent HIV infection across a subset of studies with the same exposure period. Analyses were conducted separately for men and women.

Results

Nineteen papers from 16 studies met our inclusion criteria. Of these 16 studies, 14 provided data on women and 10 on men. We find a significant, positive, unadjusted or adjusted association between transactional sex and HIV in 10 of 14 studies for women, one of which used a longitudinal design (relative risk (RR)=2.06, 95% confidence interval (CI): 1.22 –3.48). Out of 10 studies involving men, only 2 indicate a positive association between HIV and transactional sex in unadjusted or adjusted models. The meta-analysis confirmed general findings from the systematic review (unadjusted meta-analysis findings are significant for women (n=4; pooled odds ratio (OR)=1.54, 95% CI: 1.04–2.28; I²=42.5%, p=0.156), but not for men (n=4; pooled OR=1.47, 95% CI: 0.85–2.56; I²=50.8%, p=0.107).

Conclusions

Transactional sex is associated with HIV among women, whereas findings for men were inconclusive. Given that only two studies used a longitudinal approach, there remains a need for better measurement of the practice of transactional sex and additional longitudinal studies to establish the causal pathways between transactional sex and HIV.

Characterizing the Individual, Social, and Structural Determinants of Condom Use Among Men Who Have Sex with Men in Swaziland

Within the broadly generalized HIV epidemic in Swaziland, men who have sex with men (MSM) have specific HIV acquisition and transmission risks. In the current era of expanding antiretroviral therapy-based prevention and treatment approaches, condom use remains a core component of mitigating these risks. A cross-sectional study characterizing the vulnerabilities for HIV among MSM in Swaziland was analyzed to describe factors associated with condom use at last sex with a male partner. Bivariate and multivariate logistic regression analyses were conducted to assess correlates of condom use at last sex with both casual and regular male partners. Disclosure of sexual practices to a healthcare provider and being able to count on other MSM to support condom use were significantly associated with condom use at last sex with a causal and a regular partner, respectively. Reporting difficulty insisting on condom use was inversely associated with condom use at last sex with both regular and casual partners. In addition, having faced legal discrimination was similarly inversely associated with condom use at last sex with a regular partner. Condom use among MSM in Swaziland may increase with improved partner communication, provider sensitization to encourage sexual disclosure, and the promotion of safer sex norms within MSM communities. These approaches, in combination with existing and emerging evidence of informed and human rights affirming prevention and HIV treatment approaches may reduce the incidence of HIV among MSM in Swaziland and all those in their sexual networks.

HIV Risk Among Men Who Have Sex With Men, Women Who Have Sex With Women, Lesbian, Gay, Bisexual and Transgender Populations in South Africa: A Mini-Review

BACKGROUND

The HIV epidemic in South Africa is characterized mainly by heterosexual transmission. Recently, the importance of targeting key populations and marginalized groups, including men who have sex with men (MSM) and transgender people, has been added to the national agenda.

OBJECTIVES

This mini-review explores the current state of empirical research on HIV risk and MSM, women who have sex with women (WSW), lesbian, gay, bisexual and transgender (LGBT) populations in South Africa in order to assess the current state of research and identify gaps in the literature.

METHOD

Peer-reviewed empirical social and behavioral articles on HIV prevalence and risk focusing on MSM, WSW, and LGBT populations published since 2006 were included in this mini-review.

RESULTS

In total 35 articles were included: 30 on MSM, gay, and/or bisexual male-identified populations, three on WSW, lesbian, and/or bisexual female-identified populations, two on LGB youth, and none on transgender populations.

CONCLUSION

Despite South Africa being the country with the largest number of people living with HIV in the world, there is a limited amount of research in South Africa on HIV and non-normative gender identities and sexualities, especially WSW, lesbian, and/or bisexual female-identified populations, transgender populations, and LGB youth. Research with MSM, WSW, and LGBT populations should be prioritized in South Africa in order to appropriately inform HIV prevention strategies that meet the specific needs of these marginalized groups.

A social network typology and sexual risk-taking among men who have sex with men in Cape Town and Port Elizabeth, South Africa

Despite the high prevalence of HIV among men who have sex with men in South Africa, very little is known about their lived realities, including their social and sexual networks. Given the influence of social network structure on sexual risk behaviours, a better understanding of the social contexts of men who have sex with men is essential for informing the design of HIV programming and messaging. This study explored social network connectivity, an understudied network attribute, examining self-reported connectivity between friends, family and sex partners. Data were collected in Cape Town and Port Elizabeth, South Africa, from 78 men who have sex with men who participated in in-depth interviews that included a social network mapping component. Five social network types emerged from the content analysis of these social network maps based on the level of connectivity between family, friends and sex partners, and ranged from disconnected to densely connected networks. The ways in which participants reported sexual risk-taking differed across the five network types, revealing diversity in social network profiles. HIV programming and messaging for this population can greatly benefit from recognising the diversity in lived realities and social connections between men who have sex with men.

A qualitative study of discourses on heterosexual anal sexual practice among key, and general populations in Tanzania: implications for HIV prevention

Background

The risk of contracting HIV through heterosexual anal sex (HAS) is significantly higher than from vaginal intercourse. Little has been done to understand the discourses around HAS and terms people use to describe the practice in Tanzania. A better understanding of discourses on HAS would offer useful insights for measurement of the practice as well as designing appropriate interventions to minimise the risks inherent in the practice.

Methods

This study employed qualitative approaches involving 24 focus group discussions and 81 in-depth interviews. The study was conducted in 4 regions of Tanzania, and included samples from the general population and among key population groups (fishermen, truck drivers, sex workers, food and recreational facilities workers). Discourse analysis was conducted with the aid of NVIVO versions 8 and 10 software.

Results

Six discourses were delineated in relation to how people talked about HAS. Secrecy versus openness discourse describes the terms used when talking about HAS. “Other” discourse involved participants’ perception of HAS as something practiced by others unrelated to them and outside their communities. Acceptability/trendiness discourse: young women described HAS as something trendy and increasingly gaining acceptability in their communities. Materiality discourse: describes HAS as a practice that was more profitable than vaginal sex. Masculinity discourse involved discussions on men proving their manhood by engaging in HAS especially when women initiated the practice. Masculine attitudes were also reflected in how men described the practice using a language that would be considered crude. Public health discourse: describes HAS as riskier for HIV infection than vaginal sex. The reported use of condoms was low due to the perceptions that condoms were unsuitable for anal sex, but also perceptions among some participants that anal sex was safer than vaginal sex.

Conclusion

Discourses among young women and adult men across the study populations were supportive of HAS. These findings provide useful insights in understanding how different population groups talked about HAS and offer a range of terms that interventions and further research on magnitude of HAS could draw on when addressing health risks of HAS among different study populations.

A network-level explanation for the differences in HIV prevalence in South Africa's racial groups

Analyses of individual-level risk factors have not been able to adequately explain why HIV has spread so extensively in southern Africa and why this has occurred especially within certain racial or ethnic groups. Using data from a longitudinal study of a representative sample of adolescents aged 14-22 living in Cape Town, South Africa, this article presents evidence of how differences in individual-level risk factors as well as sexual network structures between different racial or ethnic groups may help explain the differential spread of HIV in South Africa. Particular emphasis is placed on how levels of partner concurrency, respondent concurrency, mutual concurrency, serial concurrency and numbers of sexual partners and an average early age of sexual debut combine in different ways in the different racial or ethnic groups to create networks of sexual partnerships that differ in the density of their interconnections and hence potential for HIV spread. These network-level differences offer a potential explanation for the observed generalised HIV epidemic seen among the population of black South Africans.

The relationship between hegemonic norms of masculinity and men's conceptualization of sexually coercive acts by women in South Africa

While sexual abuse against women and girls in South Africa has generated much deserved attention, the awareness of men's experiences of sexual coercion is limited, and often restricted to a homosexual context. This article illuminates men's experiences of pressurized sex in a heterosexual context, which were revealed in a broader men's sexual health study. Fifty sexual history narrative interviews were conducted with men purposively sampled from three age categories: (18-24, 25-54, and 55+), a wide range of cultural and racial backgrounds, and in urban and rural sites across five provinces in South Africa. Narrative interviews began with accounts of early knowledge of sex and sexual experimentation and explored the range of sexual relationships and experiences through adulthood. The narratives privileged the diversity of men's conceptualizations of and the impact of reportedly sexually coercive experiences by women. Many men described feeling unready for their first sexual experiences but pressured to do so by their peers and female partners, who were often older. There were also some instances of sexual coercion by women against men, some of which would constitute a criminal offense in South Africa. Due to the pressure for men to always be responsive to women's sexual desires, these experiences were often not framed as sexual coercion. Nevertheless, for many of these men, such experiences were uncomfortable and unrewarding. Men's negative responses to such experiences appeared to be linked to the fact that they did not fit social stereotypes of masculine sexuality as being initiative and dominant. Such coercive experiences could influence men's sexual risk-taking, including their use of sexual coercion against women. Research on sexual abuse should not be limited to male against male sexual abuse, but needs to explore the meanings and experiences associated with reported coercion against men by women to more comprehensively prevent and respond to sexual violence.

Marital infidelity and intimate partner violence in rural Malawi: a dyadic investigation

Extramarital sexual partnerships are a common reason for intimate partner violence (IPV) in sub-Saharan Africa. Despite the fact that IPV requires an interaction between two partners, the majority of the research focuses on individuals rather than the broader relationship context where such violence takes place. Using a sample of 422 married couples from rural Malawi, this study examined the dyadic environment of marital infidelity and two types of IPV victimization: sexual coercion and physical abuse. We considered both self-reported marital infidelity and perceived partner infidelity to assess how well partners knew each other and to compare their respective associations with IPV. Logistic regression was used to test for associations between self-reported marital infidelity and IPV. Multilevel logistic regression was used to examine actor and partner effects of perceived partner infidelity on an individual's and their partner's experience of IPV. The results show that self-reported marital infidelity was not significantly associated with IPV for men or women. However, the perception of a partner's infidelity was significantly associated with both an individual's and their partner's risk for sexual coercion and physical abuse. Contrary to the "sexual double standard" hypothesis, women were not significantly more likely than men to report being physically abused when their partners suspected infidelity. Future studies should continue to explore the relationship context of IPV in sub-Saharan Africa in order to understand how spouses mutually shape each other's experience of IPV and subsequent health outcomes.

A cross-sectional assessment of the burden of HIV and associated individual- and structural-level characteristics among men who have sex with men in Swaziland

Introduction

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.

Methods

In 2011, 324 men who reported sex with another man in the last 12 months were accrued using respondent-driven sampling (RDS). Participants completed HIV testing using Swazi national guidelines as well as structured survey instruments administered by trained staff, including modules on demographics, individual-level behavioural and biological risk factors, social and structural characteristics and uptake of HIV services. Population and individual weights were computed separately for each variable with a data-smoothing algorithm. The weights were used to estimate RDS-adjusted univariate estimates with 95% bootstrapped confidence intervals (BCIs). Crude and RDS-adjusted bivariate and multivariate analyses were completed with HIV as the dependent variable.

Results

Overall, HIV prevalence was 17.6% (n=50/284), although it was strongly correlated with age in bivariate- [odds ratio (OR) 1.2, 95% BCI 1.15–1.21] and multivariate-adjusted analyses (adjusted OR 1.24, 95% BCI 1.14–1.35) for each additional year of age. Nearly, 70.8% (n=34/48) were unaware of their status of living with HIV. Condom use with all sexual partners and condom-compatible-lubricant use with men were reported by 1.3% (95% CI 0.0–9.7).

Conclusions

Although the epidemic in Swaziland is driven by high-risk heterosexual transmission, the burden of HIV and the HIV prevention, treatment and care needs of MSM have been understudied. The data presented here suggest that these men have specific HIV acquisition and transmission risks that differ from those of other reproductive-age adults. The scale-up in HIV services over the past decade has likely had limited benefit for MSM, potentially resulting in a scenario where epidemics of HIV among MSM expand in the context of slowing epidemics in the general population, a reality observed in most of the world.

Is younger really safer? A qualitative study of perceived risks and benefits of age-disparate relationships among women in Cape Town, South Africa

Young women in age-asymmetric relationships may be at an elevated risk for acquisition of HIV, since relationships with older men are also correlated with other risk behaviors like less condom use. Qualitative studies have shown that women are motivated to participate in these relationships for money and emotional support. However, there is a paucity of research on women’s perceived risks of these relationships, particularly in South Africa. To this end, we conducted in-depth interviews with 23 women recruited from three urban communities in Cape Town. A thematic question guide was used to direct the interviews. Thematic content analysis was used to explore women’s perceived risks of age-disparate and non-age-disparate relationships, the benefits of dating older men, and risk perceptions that influence decisions around beginning or ending a relationship. A plurality of women thought that dating an older man does not bring any adverse consequences, although some thought that older men do not use condoms and may be involved in concurrent partnerships. Many women were less inclined to date same-age or younger men, because they were viewed as being disrespectful and abusive. This study points to the need for more awareness raising about the risks of age-disparate relationships. In addition to these initiatives, there is an urgent need to implement holistic approaches to relationship health, in order to curb intimate partner violence, improve gender equity and make non-age-disparate relationships more attractive.

It takes 2: partner attributes associated with sexually transmitted infections among adolescents

OBJECTIVES

The aims of this study were to identify partner attributes associated with sexually transmitted infections (STIs) among adolescents and to summarize implications for research and prevention.

DESIGN

The design of this study was systematic review.

METHODS

We identified peer-reviewed studies published in 1990 through 2010 that assessed 1 or more partner attributes in relation to a biologically confirmed STI among adolescents (15-24 years) by searching MEDLINE and included articles. Studies that included adolescents but more than 50% of the sample or with mean or median age of 25 years or greater were excluded.

RESULTS

Sixty-four studies met the eligibility criteria; 61% were conducted in high-income countries; 80% were cross sectional; and 91% enrolled females and 42% enrolled males. There was no standard "partner" definition. Partner attributes assessed most frequently included the following: age, race/ethnicity, multiple sex partners, and STI symptoms. Older partners were associated with prevalent STIs but largely unrelated to incidence. Black race was associated with STIs but not uniformly. Partners with multiple partners and STI symptoms seem to be associated with STIs predominantly among females. Although significant associations were reported, weaker evidence exists for the following: other partner sociodemographics, sexual and other behaviors (sexual concurrency, intimate partner violence, substance use, travel), and STI history. There were no apparent differences by STI.

CONCLUSIONS

Partner attributes are independently associated with STIs among male and female adolescents worldwide. These findings reinforce the importance of assessing partner attributes when determining STI risk. Prevention efforts should continue to promote and address barriers to condom use. Increased efforts are needed to screen and treat STIs and reduce risky behavior among men. A standard partner definition would facilitate the interpretation of findings in future studies.

The implications of respondent concurrency on sex partner risk in a national, web-based study of men who have sex with men in the United States

BACKGROUND

Men who have sex with men (MSM) represent the largest HIV risk group in the United States. Sexual concurrency catalyzes HIV transmission in populations by increasing the indirect exposure of one's sex partners to one another. Although individual-level (egocentric) designs have demonstrated a high prevalence of concurrency among MSM respondents, methods are lacking for understanding the exposure implications for partners (dyads) reported in such studies.

METHODS

A new technique for manipulating egocentrically collected partnership timing data to measure the degree to which respondents' patterns of concurrency and serial monogamy resulted in the indirect exposure of respondents' partners to other partners was developed. Two outcomes were constructed for each partner: any concurrent or serially monogamous exposure to another partner (any exposure) and any concurrent exposure to another partner, irrespective of serial monogamy (any concurrent exposure). Reports of unprotected anal intercourse (UAI) were incorporated to construct the outcomes of 'any UAI exposure' and 'any concurrent UAI exposure.' This method was applied to an online study of MSM aged ≥18 years, with comparisons made by partner's race-ethnicity, age, type, and meeting location.

RESULTS

Among 4060 repeat partners of 2449 MSM, 73% had any exposure in the previous 6 months; 58% had any concurrent exposure. Among UAI partners, 37% had concurrent UAI exposure. Black UAI partners were more likely than whites to have any concurrent UAI exposure [unadjusted odds ratio (95% confidence interval) = 1.34 (1.05 to 1.70)], as were casual UAI partners relative to main partners [unadjusted odds ratio (95% confidence interval) = 4.37 (3.58 to 5.35)]. In adjusted models, black UAI partners were significantly more likely to have any UAI exposure, but not concurrent UAI exposure. Casual UAI partners remained more exposed by both outcomes.

CONCLUSIONS

Sex partners of MSM, particularly casual and black non-Hispanic partners, face a high degree of exposure to other partners.

The relevance of social contexts and social action in reducing substance use and victimization among women participating in an HIV prevention intervention in Cape Town, South Africa

Objectives

To examine qualitatively how women’s social context and community mobilization (eg, mobilizing women to take social action and engaging their community in social change) influence substance use abstinence and victimization among women participating in a human immunodeficiency virus (HIV) intervention in Cape Town, South Africa.

Methods

Thirty women who had participated in a randomized controlled trial of a group-delivered intervention to address substance use, gender-based violence, and associated risk for HIV (The Women’s Health CoOp) were selected to participate in semi-structured interviews about their perceived impact of the intervention on their substance use and exposure to victimization. The Women’s CoOp intervention involved creating a new positive social environment for women within a group setting that also fostered women’s social action (eg, educating peers or family members) in the community. Interviews were analyzed using content analysis and coded to examine women’s descriptions of social contexts and social action, and the influence of these on women’s substance use abstinence and exposure to victimization.

Results

Social support (eg, via program staff and other participants) and social action (eg, engaging others in the community on issues relevant to substance use prevention or other health topics) promoted within the program, as well as outside social influences within women’s life contexts (eg, support from non-substance using family or male partners, leaving male partners or other peer relationships characterized by drug use, or finding employment) were key factors reported by women in terms of facilitating their substance use abstinence and in reducing women’s exposures to victimization.

Conclusion

Findings highlight the potential for group-delivered interventions that include mobilizing women to take social action in the larger community to be effective approaches for facilitating substance use abstinence, reductions in victimization, and ultimately, to address the intersection between substance use, violence, and HIV risk among women in this high HIV prevalence setting.

A decade of research involving men who have sex with men in sub-Saharan Africa: current knowledge and future directions

It has been just over 10 years since the first large behavioral survey of men who have sex with men (MSM) was implemented in Senegal in 2001. Since then, behavioral and/or HIV prevalence surveys have been conducted in over 14 other countries in sub-Saharan Africa. Current available evidence and review have established that HIV prevalence among MSM in these countries are significantly higher than corresponding general populations, that MSM engage in sexual risk behaviors that place them and sexual partners at higher risk, and that issues of discrimination and stigmatization inhibit HIV interventions for MSM. This paper summarizes the existing knowledge, describes limitations of this evidence, and proposes new and enhanced research approaches to fulfill needed gaps to inform national HIV responses for MSM populations.

Why MSM in rural South African communities should be an HIV prevention research priority

Research into HIV and men who have sex with men’s (MSM) health in South Africa has been largely confined to the metropolitan centres. Only two studies were located making reference to MSM in rural contexts or same-sex behaviors among men in the same. There is growing recognition in South Africa that MSM are not only disproportionately affected by HIV and have been underserved by the country’s national response, but that they contribute significantly to sustaining the high number of new infections recorded each year. We argue that to meet the objectives of the country’s national strategic plan for HIV, STI and TB it is important we know how these behaviours may be contributing to the sustained rural HIV epidemic in the youngest age groups and determine what constitutes appropriate and feasible programmatic response that can be implemented in the country’s public sector health services.

Prevalence of consensual male-male sex and sexual violence, and associations with HIV in South Africa: a population-based cross-sectional study

BACKGROUND

In sub-Saharan Africa the population prevalence of men who have sex with men (MSM) is unknown, as is the population prevalence of male-on-male sexual violence, and whether male-on-male sexual violence may relate to HIV risk. This paper describes lifetime prevalence of consensual male-male sexual behavior and male-on-male sexual violence (victimization and perpetration) in two South African provinces, socio-demographic factors associated with these experiences, and associations with HIV serostatus.

METHODS AND FINDINGS

In a cross-sectional study conducted in 2008, men aged 18-49 y from randomly selected households in the Eastern Cape and KwaZulu-Natal provinces provided anonymous survey data and dried blood spots for HIV serostatus assessment. Interviews were completed in 1,737 of 2,298 (75.6%) of enumerated and eligible households. From these households, 1,705 men (97.1%) provided data on lifetime history of same-sex experiences, and 1,220 (70.2%) also provided dried blood spots for HIV testing. 5.4% (n = 92) of participants reported a lifetime history of any consensual sexual activity with another man; 9.6% (n = 164) reported any sexual victimization by a man, and 3.0% (n = 51) reported perpetrating sexual violence against another man. 85.0% (n = 79) of men with a history of consensual sex with men reported having a current female partner, and 27.7% (n = 26) reported having a current male partner. Of the latter, 80.6% (n = 21/26) also reported having a female partner. Men reporting a history of consensual male-male sexual behavior are more likely to have been a victim of male-on-male sexual violence (adjusted odds ratio [aOR] = 7.24; 95% CI 4.26-12.3), and to have perpetrated sexual violence against another man (aOR = 3.10; 95% CI 1.22-7.90). Men reporting consensual oral/anal sex with a man were more likely to be HIV+ than men with no such history (aOR = 3.11; 95% CI 1.24-7.80). Men who had raped a man were more likely to be HIV+ than non-perpetrators (aOR = 3.58; 95% CI 1.17-10.9).

CONCLUSIONS

In this sample, one in 20 men (5.4%) reported lifetime consensual sexual contact with a man, while about one in ten (9.6%) reported experience of male-on-male sexual violence victimization. Men who reported having had sex with men were more likely to be HIV+, as were men who reported perpetrating sexual violence towards other men. Whilst there was no direct measure of male-female concurrency (having overlapping sexual relationships with men and women), the data suggest that this may have been common. These findings suggest that HIV prevention messages regarding male-male sex in South Africa should be mainstreamed with prevention messages for the general population, and sexual health interventions and HIV prevention interventions for South African men should explicitly address male-on-male sexual violence.

Unwanted sexual experiences among young men in four sub-Saharan African countries: prevalence and context

Unwanted sexual experiences are most frequently examined from the woman's perspective, yet these experiences happen to men as well. Part of the reason for the paucity of studies on coerced sexual experiences among men is the difficulty in gathering information about such experiences. This study examines the prevalence of unwanted sexual experiences at sexual debut as well as ever among young men aged 12-19 years old in Burkina Faso, Ghana, Malawi and Uganda. The data come from nationally-representative surveys and in-depth interviews with approximately 50 young men in each country gathered around 2004. Between 4 and 12% of young men stated that they were 'not willing at all' at sexual debut and between 3 and 6% said that they had ever experienced unwanted sex. Narratives from in-depth interviews give insights into the context surrounding men's unwanted sexual experiences. The sometimes conflicting information provided by the respondents serve to confound rather than illuminate the contexts within which these unwanted sexual experiences occurred, demonstrating that coercion for young men looks extremely different than coercion for young women, spurring us to improve our measures of sexual coercion among men.

Variation in concurrent sexual partnerships and sexually transmitted diseases among African men in Cape Town, South Africa

BACKGROUND

Most studies that assess the relationship between concurrent sexual partnerships and sexually transmitted diseases (STDs) use dichotomous measures of whether concurrency was reported or not. However, different forms of concurrency have different degrees of associated risk for disease transmission, and this should be considered. This article examines variation in both individual concurrency and partner concurrency among African men in Cape Town, South Africa, and assesses the relationship between different types of concurrent partnerships and STDs.

METHODS

Longitudinal data from sexual partner history tables are used to form measures of concurrency and the type of partner (main vs. nonmain) and degree of condom use (consistent vs. inconsistent) associated with these concurrent relationships. Cross-sectional data from a self-administered module are also used to assess the number of partners men have had concurrently and duration of individual concurrency. Probit regression models assess the association between the partner concurrency measures and self-reported STD history.

RESULTS

Substantial differences between concurrent sexual partnerships were observed and these variations were associated with different disease risk. Men had a greater chance of reporting an STD when partner concurrency was associated with main partners and inconsistent condom use.

CONCLUSION

Partnership dynamics must be taken into account in studies assessing the role of concurrency in STD transmission.

Male circumcision

Male circumcision consists of the surgical removal of some, or all, of the foreskin (or prepuce) from the penis. It is one of the most common procedures in the world. In the United States, the procedure is commonly performed during the newborn period. In 2007, the American Academy of Pediatrics (AAP) convened a multidisciplinary workgroup of AAP members and other stakeholders to evaluate the evidence regarding male circumcision and update the AAP's 1999 recommendations in this area. The Task Force included AAP representatives from specialty areas as well as members of the AAP Board of Directors and liaisons representing the American Academy of Family Physicians, the American College of Obstetricians and Gynecologists, and the Centers for Disease Control and Prevention. The Task Force members identified selected topics relevant to male circumcision and conducted a critical review of peer-reviewed literature by using the American Heart Association's template for evidence evaluation. Evaluation of current evidence indicates that the health benefits of newborn male circumcision outweigh the risks; furthermore, the benefits of newborn male circumcision justify access to this procedure for families who choose it. Specific benefits from male circumcision were identified for the prevention of urinary tract infections, acquisition of HIV, transmission of some sexually transmitted infections, and penile cancer. Male circumcision does not appear to adversely affect penile sexual function/sensitivity or sexual satisfaction. It is imperative that those providing circumcision are adequately trained and that both sterile techniques and effective pain management are used. Significant acute complications are rare. In general, untrained providers who perform circumcisions have more complications than well-trained providers who perform the procedure, regardless of whether the former are physicians, nurses, or traditional religious providers. Parents are entitled to factually correct, nonbiased information about circumcision and should receive this information from clinicians before conception or early in pregnancy, which is when parents typically make circumcision decisions. Parents should determine what is in the best interest of their child. Physicians who counsel families about this decision should provide assistance by explaining the potential benefits and risks and ensuring that parents understand that circumcision is an elective procedure. The Task Force strongly recommends the creation, revision, and enhancement of educational materials to assist parents of male infants with the care of circumcised and uncircumcised penises. The Task Force also strongly recommends the development of educational materials for providers to enhance practitioners' competency in discussing circumcision's benefits and risks with parents. The Task Force made the following recommendations:Evaluation of current evidence indicates that the health benefits of newborn male circumcision outweigh the risks, and the benefits of newborn male circumcision justify access to this procedure for those families who choose it. Parents are entitled to factually correct, nonbiased information about circumcision that should be provided before conception and early in pregnancy, when parents are most likely to be weighing the option of circumcision of a male child. Physicians counseling families about elective male circumcision should assist parents by explaining, in a nonbiased manner, the potential benefits and risks and by ensuring that they understand the elective nature of the procedure. Parents should weigh the health benefits and risks in light of their own religious, cultural, and personal preferences, as the medical benefits alone may not outweigh these other considerations for individual families. Parents of newborn boys should be instructed in the care of the penis, regardless of whether the newborn has been circumcised or not. Elective circumcision should be performed only if the infant's condition is stable and healthy. Male circumcision should be performed by trained and competent practitioners, by using sterile techniques and effective pain management. Analgesia is safe and effective in reducing the procedural pain associated with newborn circumcision; thus, adequate analgesia should be provided whenever newborn circumcision is performed.Nonpharmacologic techniques (eg, positioning, sucrose pacifiers) alone are insufficient to prevent procedural and postprocedural pain and are not recommended as the sole method of analgesia. They should be used only as analgesic adjuncts to improve infant comfort during circumcision. If used, topical creams may cause a higher incidence of skin irritation in low birth weight infants, compared with infants of normal weight; penile nerve block techniques should therefore be chosen for this group of newborns. Key professional organizations (AAP, the American Academy of Family Physicians, the American College of Obstetricians and Gynecologists, the American Society of Anesthesiologists, the American College of Nurse Midwives, and other midlevel clinicians such as nurse practitioners) should work collaboratively to:Develop standards of trainee proficiency in the performance of anesthetic and procedure techniques, including suturing; Teach the procedure and analgesic techniques during postgraduate training programs; Develop educational materials for clinicians to enhance their own competency in discussing the benefits and risks of circumcision with parents; Offer educational materials to assist parents of male infants with the care of both circumcised and uncircumcised penises. The preventive and public health benefits associated with newborn male circumcision warrant third-party reimbursement of the procedure. The American College of Obstetricians and Gynecologists has endorsed this technical report.

Molecular epidemiology of HIV-1 transmission in a cohort of HIV-1 concordant heterosexual couples from Dakar, Senegal

Background

A large number of HIV-1 infections in Africa occur in married couples. The predominant direction of intracouple transmission and the principal external origins of infection remain important issues of debate.

Methods

We investigated HIV-1 transmission in 46 HIV-1 concordant positive couples from Dakar, Senegal. Intracouple transmission was confirmed by maximum-likelihood phylogenetic analysis and pairwise distance comparisons of HIV-1 env gp41 sequences from both partners. Standardized interview data were used to deduce the direction as well as the external sources of the intracouple transmissions.

Results

Conservative molecular analyses showed linked viruses in 34 (74%) couples, unlinked viruses in 6 (13%) couples, and indeterminate results for 6 (13%) couples. The interview data corresponded completely with the molecular analyses: all linked couples reported internal transmission and all unlinked couples reported external sources of infection. The majority of linked couples (93%) reported the husband as internal source of infection. These husbands most frequently (82%) reported an occasional sexual relationship as external source of infection. Pairwise comparisons of the CD4 count, antiretroviral therapy status, and the proportion of gp41 ambiguous base pairs within transmission pairs correlated with the reported order of infection events.

Conclusions

In this suburban Senegalese population, a majority of HIV-1 concordant couples showed linked HIV-1 transmission with the husband as likely index partner. Our data emphasize the risk of married women for acquiring HIV-1 as a result of the occasional sexual relationships of their husbands.

HIV risk and associations of HIV infection among men who have sex with men in peri-urban Cape Town, South Africa

Background

The HIV epidemic in Sub Saharan Africa has been traditionally assumed to be driven by high risk heterosexual and vertical transmission. However, there is an increasing body of data highlighting the disproportionate burden of HIV infection among MSM in the generalized HIV epidemics across of Southern Africa. In South Africa specifically, there has been an increase in attention focused on the risk status and preventive needs of MSM both in urban centers and peri-urban townships. The study presented here represents the first evaluation of HIV prevalence and associations of HIV infection among MSM in the peri-urban townships of Cape Town.

Methods

The study consisted of an anonymous probe of 200 men, reporting ever having had sex with another man, recruited through venue-base sampling from January to February, 2009.

Results

Overall, HIV prevalence was 25.5% (n = 51/200). Of these prevalent HIV infections, only 6% of HIV-1 infected MSM were aware of their HIV status (3/50). 0% of men reported always having safe sex as defined by always wearing condoms during sex and using water-based lubricants. Independent associations with HIV infection included inconsistent condom use with male partners (aOR 2.3, 95% CI 1.0-5.4), having been blackmailed (aOR 4.4, 95% CI 1.6-20.2), age over 26 years (aOR 4.2, 95% CI 1.6-10.6), being unemployed (aOR 3.7, 95% CI 1.5-9.3), and rural origin (aOR 6.0, 95% CI 2.2-16.7). Bisexual activity was reported by 17.1% (34/199), and a total of 8% (16/200) reported having a regular female partner. Human rights violations were common with 10.5% (n = 21/200) reporting having been blackmailed and 21.0% (n = 42/200) reporting being afraid to seek health care.

Conclusions

The conclusions from this study include that a there is a high risk and underserved population of MSM in the townships surrounding Cape Town. The high HIV prevalence and high risk sexual practices suggest that prevalence will continue to increase among these men in the context of an otherwise slowing epidemic. These data further highlight the need to better characterize risk factors for HIV prevention and appropriate targeted combination packages of HIV interventions including biomedical, behavioural, and structural approaches to mitigate HIV risk among these men.

The relationship between intimate partner violence, rape and HIV amongst South African men: a cross-sectional study

Objective

To investigate the associations between intimate partner violence, rape and HIV among South African men.

Design

Cross-sectional study involving a randomly-selected sample of men.

Methods

We tested hypotheses that perpetration of physical intimate partner violence and rape were associated with prevalent HIV infections in a cross-sectional household study of 1229 South African men aged 18–49. Violence perpetration was elicited in response to a questionnaire administered using an Audio-enhanced Personal Digital Assistant and blood samples were tested for HIV. A multivariable logistic regression model was built to identify factors associated with HIV.

Results

18.3% of men had HIV. 29.6% (358/1211) of men disclosed rape perpetration, 5.2% (63/1208) rape in the past year and 30.7% (362/1180) of had been physically violent towards an intimate partner more than once. Overall rape perpetration was not associated with HIV. The model of factors associated with having HIV showed men under 25 years who had been physically violent towards partners were more likely to have HIV than men under 25 who had not (aOR 2.08 95% CI 1.07–4.06, p = 0.03). We failed to detect any association in older men.

Conclusions

Perpetration of physical IPV is associated with HIV sero-prevalence in young men, after adjusting for other risk factors. This contributes to our understanding of why women who experience violence have a higher HIV prevalence. Rape perpetration was not associated, but the HIV prevalence among men who had raped was very high. HIV prevention in young men must seek to change ideals of masculinity in which male partner violence is rooted.

Male circumcision for prevention of homosexual acquisition of HIV in men

BACKGROUND

Previous systematic reviews found inconsistent effects of male circumcision on HIV acquisition in men who have sex with men (MSM). However, a number of new studies have become available in the three years since the last systematic review.

OBJECTIVES

To assess the effects of male circumcision for preventing HIV acquisition by men through sex with men.

SEARCH STRATEGY

In June 2010 we electronically searched the Cochrane Central Register of Controlled Trials, PubMed, EMBASE, AIDS Education Global Information System, ClinicalTrials.gov, and WHO International Clinical Trials Registry Platform; hand-searched reference lists of relevant articles; and contacted relevant organisations and experts. We updated the search in March 2011.

SELECTION CRITERIA

We looked for randomised controlled trials (RCTs) and observational studies that assessed the effects of male circumcision on HIV acquisition in MSM.

DATA COLLECTION AND ANALYSIS

Two authors independently assessed study eligibility and methodological quality, and extracted data. We expressed study results as odds ratios (OR) with 95% confidence intervals (CI), and conducted random-effects meta-analysis.

MAIN RESULTS

We found no completed RCT and included 21 observational studies with 71,693 participants. The only eligible RCT is currently ongoing among MSM in China. The pooled effect estimate for HIV acquisition was not statistically significant (20 studies; 65,784 participants; OR 0.86, 95% CI 0.70 to 1.06) and showed significant heterogeneity (I²=53%). In a subgroup analysis, the results were statistically significant in studies of men reporting an insertive role (7 studies, 3465 participants; OR 0.27, 95% CI 0.17 to 0.44; I²=0%) but not in studies of men reporting a receptive role (3 studies, 1792 participants; OR 1.20, 95% CI 0.63 to 2.29; I² = 0%). There was no significant association between male circumcision and syphilis (8 studies; 34,999 participants: OR 0.96, 95% CI 0.82 to 1.13; I² = 0%), herpes simplex virus 1 (2 studies, 2740 participants; OR 0.90, 95% CI 0.53 to 1.52; I²=0%), or herpes simplex virus 2 (5 studies;10,285 participants; OR 0.86, 95% CI 0.62 to 1.21; I²=0%). The overall GRADE quality of evidence was low. None of the included studies assessed adverse effects associated with male circumcision.

AUTHORS' CONCLUSIONS

Current evidence suggests that male circumcision may be protective among MSM who practice primarily insertive anal sex, but the role of male circumcision overall in the prevention of HIV and other sexually transmitted infections among MSM remains to be determined. Therefore, there is not enough evidence to recommend male circumcision for HIV prevention among MSM at present. Further research should be of high quality and further explore interaction with the predominant sexual role.

Norms and practices within marriage which shape gender roles, HIV/AIDS risk and risk reduction strategies in Cabo Delgado, Mozambique

Despite increasing HIV/AIDS rates among married individuals, minimal research has been conducted on how men and women respond to risk in a marriage. This paper examines strategies used by married individuals to combat HIV/AIDS risk against prevailing gender norms. Qualitative data were gathered in four villages of Cabo Delgado province, Mozambique. Group discussions were held with 160 men and women to explore gender norms, HIV/AIDS knowledge and risk determinants. From the group discussions, 29 individuals were selected for further in-depth interviews to explore relationships between gender norms and risk reduction efforts within marriages. Findings illustrate how infidelity and social limitations placed on condom use not only increase HIV/AIDS risk but also entrench gender disparities. Although power differences between genders can make it difficult to negotiate safe sex, men and women are taking measures to reduce perceived HIV/AIDS risk in their marriage. Married men are reconstructing norms and taking responsibility to protect their family from HIV/AIDS by remaining faithful. For women, responses to HIV/AIDS risk in a marriage are more closely related to their ability to generate an income. Financially dependent women tend to leave a risky marriage altogether in contrast to financially autonomous women who will negotiate condom use with their husband. Factors such as experience with a risky partner, the desire to maintain a good social standing, fear of HIV/AIDS acquisition and parental guidance and support influence men and women to reduce perceived HIV/AIDS risk, despite constraining gender norms and power imbalances in a marriage. Nuanced understandings of the ways in which men and women are already taking measures to decrease noted HIV/AIDS risk, despite gender norms that make this a challenge, should be incorporated into localised responses.

Male circumcision and HIV infection risk

BACKGROUND

Male circumcision is being promoted to reduce human immunodeficiency virus type 1 (HIV) infection rates. This review evaluates the scientific evidence suggesting that male circumcision reduces HIV infection risk in high-risk heterosexual populations.

METHODS

We followed the updated International Consultation on Urological Diseases evidence-based medicine recommendations to critically review the scientific evidence on male circumcision and HIV infection risk.

RESULTS

Level 1 evidence supports the concept that male circumcision substantially reduces the risk of HIV infection. Three major lines of evidence support this conclusion: biological data suggesting that this concept is plausible, data from observational studies supported by high-quality meta-analyses, and three randomized clinical trials supported by high-quality meta-analyses.

CONCLUSIONS

The evidence from these biological studies, observational studies, randomized controlled clinical trials, meta-analyses, and cost-effectiveness studies is conclusive. The challenges to implementation of male circumcision as a public health measure in high-risk populations must now be faced.

High HIV prevalence among men who have sex with men in Soweto, South Africa: results from the Soweto Men's Study

The Soweto Men’s Study assessed HIV prevalence and associated risk factors among MSM in Soweto, South Africa. Using respondent driven sampling (RDS) recruitment methods, we recruited 378 MSM (including 15 seeds) over 30 weeks in 2008. All results were adjusted for RDS sampling design. Overall HIV prevalence was estimated at 13.2% (95% confidence interval 12.4–13.9%), with 33.9% among gay-identified men, 6.4% among bisexual-identified men, and 10.1% among straight-identified MSM. In multivariable analysis, HIV infection was associated with being older than 25 (adjusted odds ratio (AOR) 3.8, 95% CI 3.2–4.6), gay self-identification (AOR 2.3, 95% CI 1.8–3.0), monthly income less than ZAR500 (AOR 1.4, 95% CI 1.2–1.7), purchasing alcohol or drugs in exchange for sex with another man (AOR 3.9, 95% CI 3.2–4.7), reporting any URAI (AOR 4.4, 95% CI 3.5–5.7), reporting between six and nine partners in the prior 6 months (AOR 5.7, 95% CI 4.0–8.2), circumcision, (AOR 0.2, 95% CI 0.1–0.2), a regular female partner (AOR 0.2, 95% CI 0.2–0.3), smoking marijuana in the last 6 months (AOR 0.6, 95% CI 0.5–0.8), unprotected vaginal intercourse in the last 6 months (AOR 0.5, 95% CI 0.4–0.6), and STI symptoms in the last year (AOR 0.7, 95% CI 0.5–0.8). The results of the Soweto Men’s Study confirm that MSM are at high risk for HIV infection, with gay men at highest risk. HIV prevention and treatment for MSM are urgently needed.

Concurrent partnerships and HIV: an inconvenient truth

The strength of the evidence linking concurrency to HIV epidemic severity in southern and eastern Africa led the Joint United Nations Programme on HIV/AIDS and the Southern African Development Community in 2006 to conclude that high rates of concurrent sexual partnerships, combined with low rates of male circumcision and infrequent condom use, are major drivers of the AIDS epidemic in southern Africa. In a recent article in the Journal of the International AIDS Society, Larry Sawers and Eileen Stillwaggon attempt to challenge the evidence for the importance of concurrency and call for an end to research on the topic. However, their "systematic review of the evidence" is not an accurate summary of the research on concurrent partnerships and HIV, and it contains factual errors concerning the measurement and mathematical modelling of concurrency.Practical prevention-oriented research on concurrency is only just beginning. Most interventions to raise awareness about the risks of concurrency are less than two years old; few evaluations and no randomized-controlled trials of these programmes have been conducted. Determining whether these interventions can help people better assess their own risks and take steps to reduce them remains an important task for research. This kind of research is indeed the only way to obtain conclusive evidence on the role of concurrency, the programmes needed for effective prevention, the willingness of people to change behaviour, and the obstacles to change.

HIV-malaria co-infection: effects of malaria on the prevalence of HIV in East sub-Saharan Africa

OBJECTIVE

To examine the association between malaria and HIV prevalence in East sub-Saharan Africa.

METHODS

Using large nationally representative samples of 19,735 sexually active adults from the 2003-04 HIV/AIDS indicator surveys conducted in Kenya, Malawi and Tanzania, and the atlas malaria project, we analysed the relationship between malaria and HIV prevalence adjusting for important socioeconomic and biological cofactors.

RESULTS

In adjusted models, individuals who live in areas with high Plasmodium falciparum parasite rate (PfPR > 0.42) had increased estimated odds of being HIV positive than individuals who live in areas with low P. falciparum parasite rate (PfPR ≤ 0.10) [men: estimated odds ratio (OR) 2.24, 95% confidence interval (CI) 1.62-3.12; women: estimated OR 2.44, 95% CI 1.85-3.21].

CONCLUSION

This is the first study to report malaria as a risk factor of concurrent HIV infection at the population level. According to our results, individuals who live in areas with high P. falciparum parasite rate have about twice the risk of being HIV positive compared with individuals who live in areas with low P. falciparum parasite rate. Our work emphasizes the need for field studies focused on quantifying the interaction among parasitic infections and risk of HIV infection, and studies to explore the impact of control interventions. Programmes focused on reducing malaria transmission will be important to address, especially in HIV-infected individuals.

'I woke up after I joined Stepping Stones': meanings of an HIV behavioural intervention in rural South African young people's lives

Evaluation of the Stepping Stones human immunodeficiency virus (HIV) prevention programme in South Africa showed sustained reduction in men and women's herpes simplex type 2 virus incidence and male violence, but no impact on HIV in women. Companion qualitative research was undertaken to explore how participants made meaning from the programme and how it influenced their lives. In-depth interviews were conducted with 10 men and 11 women before the intervention (one to three interviews per person). Then 9-12 months later, 18 follow-up interviews and 4 focus groups were held. Stepping Stones empowered participants and engendered self-reflection, in a process circumscribed by social and cultural context. Participants generally sought to be 'better', rather than 'different', men and women. Men shaped a more benign patriarchy, i.e. less violent and anti-social, and sought to avoid potential risks, ranging from imprisonment, witchcraft to HIV. While some women showed greater assertiveness and some agency in HIV risk reduction, most challenged neither their male partners nor the existing cultural norms of conservative femininities. This may explain the lack of impact of the intervention on HIV in women, since they lacked the power to embrace a greater feminist consciousness. Stepping Stones might be more effective for women when combined with other structural interventions.

Interpersonal violence: an important risk factor for disease and injury in South Africa

BACKGROUND

Burden of disease estimates for South Africa have highlighted the particularly high rates of injuries related to interpersonal violence compared with other regions of the world, but these figures tell only part of the story. In addition to direct physical injury, violence survivors are at an increased risk of a wide range of psychological and behavioral problems. This study aimed to comprehensively quantify the excess disease burden attributable to exposure to interpersonal violence as a risk factor for disease and injury in South Africa.

METHODS

The World Health Organization framework of interpersonal violence was adapted. Physical injury mortality and disability were categorically attributed to interpersonal violence. In addition, exposure to child sexual abuse and intimate partner violence, subcategories of interpersonal violence, were treated as risk factors for disease and injury using counterfactual estimation and comparative risk assessment methods. Adjustments were made to account for the combined exposure state of having experienced both child sexual abuse and intimate partner violence.

RESULTS

Of the 17 risk factors included in the South African Comparative Risk Assessment study, interpersonal violence was the second leading cause of healthy years of life lost, after unsafe sex, accounting for 1.7 million disability-adjusted life years (DALYs) or 10.5% of all DALYs (95% uncertainty interval: 8.5%-12.5%) in 2000. In women, intimate partner violence accounted for 50% and child sexual abuse for 32% of the total attributable DALYs.

CONCLUSIONS

The implications of our findings are that estimates that include only the direct injury burden seriously underrepresent the full health impact of interpersonal violence. Violence is an important direct and indirect cause of health loss and should be recognized as a priority health problem as well as a human rights and social issue. This study highlights the difficulties in measuring the disease burden from interpersonal violence as a risk factor and the need to improve the epidemiological data on the prevalence and risks for the different forms of interpersonal violence to complete the picture. Given the extent of the burden, it is essential that innovative research be supported to identify social policy and other interventions that address both the individual and societal aspects of violence.

Timing is everything: international variations in historical sexual partnership concurrency and HIV prevalence

BACKGROUND

Higher prevalence of concurrent partnerships is one hypothesis for the severity of the HIV epidemic in the countries of Southern Africa. But measures of the prevalence of concurrency alone do not adequately capture the impact concurrency will have on transmission dynamics. The importance of overlap duration and coital exposure are examined here.

METHODOLOGY/PRINCIPAL FINDINGS

We conducted a comparison of data from three studies of sexual behavior carried out in the early 1990s in Uganda, Thailand and the US. Using cumulative concurrency measures, the three countries appeared somewhat similar. Over 50% of both Thai and Ugandan men reported a concurrency within the last three partnerships and over 20% reported a concurrency in the last year, the corresponding rates among US men were nearly 20% for Blacks and Hispanics, and about 10% for other racial/ethnic groups. Concurrency measures that were more sensitive to overlap duration, however, showed large differences. The point prevalence of concurrency on the day of interview was over 10% among Ugandan men compared to 1% for Thai men. Ugandan concurrencies were much longer duration - a median of about two years - than either the Thai (1 day) or US concurrencies (4-9 months across all groups), and involved 5-10 times more coital risk exposure with the less frequent partner. In the US, Blacks and Hispanics reported higher prevalence, longer duration and greater coital exposure than Whites, but were lower than Ugandans on nearly every measure. Together, the differences in the prevalence, duration and coital exposure of concurrent partnerships observed align with the HIV prevalence differentials seen in these populations at the time the data were collected.

CONCLUSIONS/SIGNIFICANCE

There were substantial variations in the patterns of concurrent partnerships within and between populations. More long-term overlapping partnerships, with regular coital exposure, were found in populations with greater HIV epidemic severity.

Associations between childhood adversity and depression, substance abuse and HIV and HSV2 incident infections in rural South African youth

OBJECTIVES

To describe prevalence of childhood experiences of adversity in rural South African youth and their associations with health outcomes.

METHODS

We analyzed questionnaires and blood specimens collected during a baseline survey for a cluster randomized controlled trial of a behavioral intervention, and also tested blood HIV and herpes simplex type 2 virus at 12- and 24-month follow up; 1,367 male and 1,415 female volunteers were recruited from 70 rural villages.

RESULTS

Both women and men before 18 had experienced physical punishment (89.3% and 94.4%), physical hardship (65.8% and 46.8%), emotional abuse (54.7% and 56.4%), emotional neglect (41.6% and 39.6%), and sexual abuse (39.1% and 16.7%). Incident HIV infections were more common in women who experienced emotional abuse (IRR 1.96, 95% CI 1.25, 3.06, p=.003), sexual abuse (IRR 1.66 95% CI 1.04, 2.63, p=.03), and physical punishment (IRR 2.13 95% CI 1.04, 4.37, p=.04). Emotional neglect in women was associated with depression (aOR 1.82, 95% CI 1.15, 2.88, p=.01), suicidality (aOR 5.07, 95% CI 2.07, 12.45, p<.0001), alcohol abuse (aOR 2.17, 95% CI .99, 4.72, p=.05), and incident HSV2 infections (IRR 1.62, 95% CI 1.01, 2.59, p=.04). In men emotional neglect was associated with depression (aOR 3.41, 95% CI 1.87, 6.20, p<.0001) and drug use (aOR 1.98, 95% CI 1.37, 2.88, p<.0001). Sexual abuse was associated with alcohol abuse in men (aOR 3.68, 95% CI 2.00, 6.77, p<.0001) and depression (aOR 2.16, 95% CI 1.34, 3.48, p=.002) and alcohol abuse in women (aOR 3.94, 95% CI 1.90, 8.17, p<.0001).

PRACTICE IMPLICATIONS

Childhood exposure to adversity is very common and influences the health of women and men. All forms of adversity, emotional, physical and sexual, enhance the risk of adverse health outcomes in men and women. Prevention of child abuse need to be included as part of the HIV prevention agenda in sub-Saharan Africa. Interventions are needed to prevent emotional, sexual, and physical abuse and responses from health and social systems in Africa to psychologically support exposed children must be strengthened.

Concurrent sexual partnerships do not explain the HIV epidemics in Africa: a systematic review of the evidence

The notion that concurrent sexual partnerships are especially common in sub-Saharan Africa and explain the region's high HIV prevalence is accepted by many as conventional wisdom. In this paper, we evaluate the quantitative and qualitative evidence offered by the principal proponents of the concurrency hypothesis and analyze the mathematical model they use to establish the plausibility of the hypothesis.We find that research seeking to establish a statistical correlation between concurrency and HIV prevalence either finds no correlation or has important limitations. Furthermore, in order to simulate rapid spread of HIV, mathematical models require unrealistic assumptions about frequency of sexual contact, gender symmetry, levels of concurrency, and per-act transmission rates. Moreover, quantitative evidence cited by proponents of the concurrency hypothesis is unconvincing since they exclude Demographic and Health Surveys and other data showing that concurrency in Africa is low, make broad statements about non-African concurrency based on very few surveys, report data incorrectly, report data from studies that have no information about concurrency as though they supported the hypothesis, report incomparable data and cite unpublished or unavailable studies. Qualitative evidence offered by proponents of the hypothesis is irrelevant since, among other reasons, there is no comparison of Africa with other regions.Promoters of the concurrency hypothesis have failed to establish that concurrency is unusually prevalent in Africa or that the kinds of concurrent partnerships found in Africa produce more rapid spread of HIV than other forms of sexual behaviour. Policy makers should turn attention to drivers of African HIV epidemics that are policy sensitive and for which there is substantial epidemiological evidence.

Rethinking gender, heterosexual men, and women's vulnerability to HIV/AIDS

Most HIV prevention literature portrays women as especially vulnerable to HIV infection because of biological susceptibility and men's sexual power and privilege. Conversely, heterosexual men are perceived as active transmitters of HIV but not active agents in prevention. Although the women's vulnerability paradigm was a radical revision of earlier views of women in the epidemic, mounting challenges undermine its current usefulness. We review the etiology and successes of the paradigm as well as its accruing limitations. We also call for an expanded model that acknowledges biology, gender inequality, and gendered power relations but also directly examines social structure, gender, and HIV risk for heterosexual women and men.

Violence and injuries in South Africa: prioritising an agenda for prevention

Violence and injuries are the second leading cause of death and lost disability-adjusted life years in South Africa. The overall injury death rate of 157.8 per 100,000 population is nearly twice the global average, and the rate of homicide of women by intimate partners is six times the global average. With a focus on homicide, and violence against women and children, we review the magnitude, contexts of occurrence, and patterns of violence, and refer to traffic-related and other unintentional injuries. The social dynamics that support violence are widespread poverty, unemployment, and income inequality; patriarchal notions of masculinity that valourise toughness, risk-taking, and defence of honour; exposure to abuse in childhood and weak parenting; access to firearms; widespread alcohol misuse; and weaknesses in the mechanisms of law enforcement. Although there have been advances in development of services for victims of violence, innovation from non-governmental organisations, and evidence from research, there has been a conspicuous absence of government stewardship and leadership. Successful prevention of violence and injury is contingent on identification by the government of violence as a strategic priority and development of an intersectoral plan based on empirically driven programmes and policies.

Men who have sex with men and HIV/AIDS in sub-Saharan Africa

Globally, men who have sex with men (MSM) continue to bear a high burden of HIV infection. In sub-Saharan Africa, same-sex behaviours have been largely neglected by HIV research up to now. The results from recent studies, however, indicate the widespread existence of MSM groups across Africa, and high rates of HIV infection, HIV risk behaviour, and evidence of behavioural links between MSM and heterosexual networks have been reported. Yet most African MSM have no safe access to relevant HIV/AIDS information and services, and many African states have not begun to recognise or address the needs of these men in the context of national HIV/AIDS prevention and control programmes. The HIV/AIDS community now has considerable challenges in clarifying and addressing the needs of MSM in sub-Saharan Africa; homosexuality is illegal in most countries, and political and social hostility are endemic. An effective response to HIV/AIDS requires improved strategic information about all risk groups, including MSM. The belated response to MSM with HIV infection needs rapid and sustained national and international commitment to the development of appropriate interventions and action to reduce structural and social barriers to make these accessible.

Force and temptation: contrasting South African men's accounts of coercion into sex by men and women

Men's experience of sexual coercion is seldom the subject of research, yet it is commonly reported in all settings and increasingly evidence from South Africa points to the health risks associated with sexual coercion of men by men. Thirty-one in-depth interviews were conducted with heterosexual men aged 18-25 years who were volunteers in an HIV prevention behavioural intervention evaluation in the Eastern Cape. Men chosen included some who had reported coercion by men and women in their baseline structure interviews and some who had not. Sexual coercion by men involved abuse of trust and age-related power, temptation through material goods, as well as use of aggression. The narratives were notable for the anger that was caused by these assaults. In contrast, coercion by women was framed as 'temptation'. In some cases young men were tempted by much older women and those in a position of trust and the experience did not make them feel good. There are very substantial differences in the circumstances of coercion of young men by men and women. This needs to be taken into account in the growing trend to research coercion of men and present findings in a way that equates these two experiences.

Medical circumcision and manhood initiation rituals in the Eastern Cape, South Africa: a post intervention evaluation

The objectives of this study were first, to report the adverse events reported following male circumcision performed by medical professionals after a one-day training workshop; second, to report on the attitudes towards, beliefs surrounding and experiences regarding circumcision and initiation; and third, to assess the HIV-risk behaviour of young men attending initiation schools post medical circumcision. Initiates who had been medically circumcised by trained healthcare providers were examined and interviewed on the seventh day after circumcision and, in addition, focus-group discussions were conducted with initiates. Results indicate that of the 78 initiates physically examined on the seventh day after circumcision by a trained clinical nurse, seven (9%) adverse events (complications) were found. Initiates reported mixed attitudes towards combining medical circumcision with traditional initiation. The majority of the initiates (70%) felt that they could be stigmatized as a result of choosing medical rather than traditional circumcision and 20% thought that the relationship between medical and traditionally circumcised men was hostile. Prior to circumcision, most initiates (92%) had been sexually active and had engaged in HIV-risk behaviour. Focus-group discussions revealed that sexually active initiates, when asked about sex after circumcision, indicated they wished to abstain for a short period before resuming sexual activities with intended condom use being high. Findings are promising for efforts to up-scale integrated medical circumcision alongside traditional initiation into manhood.

Factors associated with self-reported unprotected anal sex among male sex workers in Mombasa, Kenya

OBJECTIVES

: To identify social and behavioral characteristics associated with sexual risk behaviors among male sex workers who sell sex to men in Mombasa, Kenya.

METHODS

: Using time-location sampling, 425 men who had recently sold, and were currently willing to sell sex to men were invited to participate in a cross-sectional survey. A structured questionnaire was administered using handheld computers. Factors associated with self-reported unprotected anal sex with male clients in the past 30 days were identified and subjected to multivariate analysis.

RESULTS

: Thirty-five percent of respondents did not know HIV can be transmitted via anal sex, which was a significant predictor of unprotected anal sex [adjusted odds ratio (AOR) 1.92; 95% confidence interval (95% CI), 1.16-3.16]. Other associated factors included drinking alcohol 3 or more days per week (AOR, 1.63; 95% CI, 1.05-2.54), self-report of burning urination within the past 12 months (AOR, 2.07; 95% CI, 1.14-3.76), and having never been counseled or tested for HIV (AOR, 1.66; 95% CI, 1.07-2.57). Only 21.2% of respondents correctly knew that a water-based lubricant should be used with latex condoms.

CONCLUSIONS

: Male sex workers who sell sex to men in Mombasa are in acute need of targeted prevention information on anal HIV and STI transmission, consistent condom use, and correct lubrication use with latex condoms. HIV programs in Africa need to consider and develop specific prevention strategies to reach this vulnerable population.
