Gendered syndemic of intimate partner violence, alcohol misuse, and HIV risk among peri-urban, heterosexual men in South Africa.

Men whose sexual behaviors place them at risk of HIV often exhibit a "cluster" of behaviors, including alcohol misuse and violence against women. Called the "Substance Abuse, Violence and AIDS (SAVA) syndemic," this intersecting set of issues is poorly understood among heterosexual men in sub-Saharan Africa. We aim to determine cross-sectional associations between men's use of alcohol, violence, and HIV risk behaviors using a gendered syndemics lens. We conducted a baseline survey with men in an informal, peri-urban settlement near Johannesburg (Jan-Aug 2016). Audio-assisted, self-completed questionnaires measured an index of risky sex (inconsistent condom use, multiple partnerships, transactional sex), recent violence against women (Multicountry Study instrument), alcohol misuse (Alcohol Use Disorders Tool), and gender attitudes (Gender Equitable Men's Scale). We used logistic regression to test for syndemic interaction on multiplicative and additive scales and structural equation modeling to test assumptions around serially causal epidemics. Of 2454 men, 91.8% reported one or more types of risky sex. A majority of participants reported one or more SAVA conditions (1783, 71.6%). After controlling for socio-demographics, higher scores on the risky sex index were independently predicted by men's recent violence use, problem drinking, and inequitable gender views. Those men reporting all three SAVA conditions had more than 12-fold greater odds of risky sex compared to counterparts reporting no syndemic conditions. Each two-way interaction of alcohol use, gender inequitable views, and IPV perpetration was associated with a relative increase in risky sex on either a multiplicative or additive scale. A structural equation model illustrated that gender norms predict violence, which in turn predict alcohol misuse, increasing both IPV perpetration and risky sex. These data are consistent with a syndemic model of HIV risk among heterosexual men. Targeting intersections between syndemic conditions may help prevent HIV among heterosexual men in peri-urban African settings.

Process evaluation of a community mobilization intervention for preventing men's partner violence use in peri-urban South Africa.

Intimate partner violence (IPV) is experienced by one-third of women globally, yet few programs attempt to shift men's IPV perpetration. Community mobilization is a potential strategy for reducing men's IPV perpetration, but this has rarely been examined globally. We conducted a mixed-methods process evaluation alongside a trial testing community mobilization in peri-urban South Africa. We used in-depth interviews (n=114), participant observation (160 h), and monitoring and evaluation data to assess program delivery. Qualitative data (verbatim transcripts and observation notes) were managed in Dedoose using thematic coding and quantitative data were descriptively analyzed using Stata13. We learned that outreach elements of community mobilization were implemented with high fidelity, but that critical reflection and local advocacy were difficult to achieve. The context of a peri-urban settlement (characterized by poor infrastructure, migrancy, low education, social marginalization, and high levels of violence) severely limited intervention delivery, as did lack of institutional support for staff and activist volunteers. That community mobilization was poorly implemented may explain null trial findings; in the larger trial, the intervention failed to measurably reduce men's IPV perpetration. Designing community mobilization for resource-constrained settings may require additional financial, infrastructural, organizational, or political support to effectively engage community members and reduce IPV.

Associations Between Lifetime Traumatic Experiences and HIV-Risk Behaviors Among Young Men Living in Informal Settlements in South Africa: A Cross-Sectional Analysis and Structural Equation Model.

BACKGROUND: Qualitative research emphasizes men's experiences of trauma increase HIV risk. We seek to understand associations between experience of traumatic events and HIV-risk behaviors among heterosexual men in 2 trials in urban informal settlements in South Africa. METHODS: Cross-sectional surveys among men in Johannesburg and Durban, South Africa, enrolled in intervention trials. Adjusted logistic regression and structural equation modeling assessed associations between men's experiences of poverty and traumatic events, and HIV-risk behaviors (inconsistent condom use, transactional sex, and number of sex partners). We explored mediated pathways from trauma to HIV risk through mental health and alcohol, and gender attitudes. RESULTS: Among 2394 men, in adjusted logistic regression, transactional sex and 4 or more sex partners were associated with witnessing the murder of a family member, witnessing a murder of a stranger, experiencing excessive pain, been kidnapped, and witnessing a rape. More consistent condom use was associated with witnessing the murder of a family member, being kidnapped, and witnessing a rape. In 3 separate structural equation modeling pathways were consistent, trauma directly increased transactional sex, and past year sexual partners, and increased consistent condom use. Risk was increased through mental health pathways, and gender inequitable attitudes and practices. CONCLUSION: Men's HIV-risk behaviors in this population emerge at the confluence of poverty, traumatic experiences, and gender inequalities. Effective HIV-prevention interventions needs to reduce men's experiences of poverty and trauma, transform gender norms, and reduce the mental health impact of trauma.

Pathways From Food Insecurity to Intimate Partner Violence Perpetration Among Peri-Urban Men in South Africa.

INTRODUCTION: Although poverty is sometimes seen as a driver of intimate partner violence victimization, less is known about how it intersects with men's violence perpetration. Food insecurity is a sensitive marker of poverty that may have unique mechanisms leading to men's intimate partner violence perpetration given its association with gender roles and men "providing for the family." METHODS: Using cluster-based sampling, the team conducted an audio-assisted questionnaire in 2016 among men living in a peri-urban settlement near Johannesburg, South Africa. The aim was to examine the relationship between men's food insecurity and their use of past-year intimate partner violence, and to explore the pathways linking these two conditions. RESULTS: Among 2,006 currently partnered men, nearly half (48.4%) perpetrated intimate partner violence and more than half (61.4%) were food insecure. Food insecurity was associated with doubled odds of intimate partner violence (OR=2.15, 95% CI=1.73, 2.66). This association persisted after controlling for sociodemographics, relationship characteristics, and neighborhood clustering. In a structural equation model, food insecurity retained a direct relationship with men's violence perpetration and worked through indirect pathways of mental health and relationship quality. CONCLUSIONS: Addressing men's perpetration of intimate partner violence may require examination of broader structural challenges, such as food insecurity. Future interventions should consider livelihood strategies alongside relationship and mental health approaches.
