Transactional sex among women in Soweto, South Africa: prevalence, risk factors and association with HIV infection

Pilot Trial Results of Mlambe: An Economic and Relationship-Strengthening Intervention to Address Heavy Drinking and Adherence to Antiretroviral Therapy in Malawi

We evaluated the feasibility, acceptability, and preliminary efficacy of an economic and relationship-strengthening intervention to reduce heavy alcohol use among couples living with HIV in Malawi (Mlambe). Mlambe consisted of training on financial literacy and relationship skills, combined with 1:1 matched savings accounts to invest in an income-generating activity. In a randomized controlled trial, we compared Mlambe to enhanced usual care (EUC). We enrolled 78 married couples having a partner on antiretroviral therapy (ART) who reported heavy alcohol use based on the AUDIT-C. Using targets of 75%, primary outcomes included retention rates at 10 and 15-months, session attendance rates, and satisfaction with Mlambe. Exploratory outcomes were heavy alcohol use (AUDIT-C and/or PEth positive), number of drinking days in the past month, AUDIT-C score, optimal adherence to ART (95% or higher), and viral suppression. We exceeded our targets for feasibility and acceptability metrics. Retention rates were 96% at 15-months. Session attendance and satisfaction levels were both 100%. From baseline to 15-months, Mlambe participants reported decreases in mean number of drinking days (from 6.8 to 2.1) and AUDIT-C scores (from 7.5 to 3.1); while ART adherence rates improved across the same period (from 63.2 to 73.9%). Participants in Mlambe, as compared to those in EUC, had lower rates of heavy alcohol use (89.5% vs. 97.2%) and higher rates of viral suppression (100% vs. 91.9%) at 10-months. Differences between arms were not statistically significant in this small pilot study. Mlambe was highly feasible and acceptable, and shows promise for reducing heavy alcohol use and viral non-suppression among couples with HIV in a larger efficacy study.

Investigating the effects of cytokine biomarkers on HIV incidence: a case study for individuals randomized to pre-exposure prophylaxis vs. control

Introduction

Understanding and identifying the immunological markers and clinical information linked with HIV acquisition is crucial for effectively implementing Pre-Exposure Prophylaxis (PrEP) to prevent HIV acquisition. Prior analysis on HIV incidence outcomes have predominantly employed proportional hazards (PH) models, adjusting solely for baseline covariates. Therefore, models that integrate cytokine biomarkers, particularly as time-varying covariates, are sorely needed.

Methods

We built a simple model using the Cox PH to investigate the impact of specific cytokine profiles in predicting the overall HIV incidence. Further, Kaplan-Meier curves were used to compare HIV incidence rates between the treatment and placebo groups while assessing the overall treatment effectiveness. Utilizing stepwise regression, we developed a series of Cox PH models to analyze 48 longitudinally measured cytokine profiles. We considered three kinds of effects in the cytokine profile measurements: average, difference, and time-dependent covariate. These effects were combined with baseline covariates to explore their influence on predictors of HIV incidence.

Results

Comparing the predictive performance of the Cox PH models developed using the AIC metric, model 4 (Cox PH model with time-dependent cytokine) outperformed the others. The results indicated that the cytokines, interleukin (IL-2, IL-3, IL-5, IL-10, IL-16, IL-12P70, and IL-17 alpha), stem cell factor (SCF), beta nerve growth factor (B-NGF), tumor necrosis factor alpha (TNF-A), interferon (IFN) alpha-2, serum stem cell growth factor (SCG)-beta, platelet-derived growth factor (PDGF)-BB, granulocyte macrophage colony-stimulating factor (GM-CSF), tumor necrosis factor-related apoptosis-inducing ligand (TRAIL), and cutaneous T-cell-attracting chemokine (CTACK) were significantly associated with HIV incidence. Baseline predictors significantly associated with HIV incidence when considering cytokine effects included: age of oldest sex partner, age at enrollment, salary, years with a stable partner, sex partner having any other sex partner, husband's income, other income source, age at debut, years lived in Durban, and sex in the last 30 days.

Discussion

Overall, the inclusion of cytokine effects enhanced the predictive performance of the models, and the PrEP group exhibited reduced HIV incidences compared to the placebo group.

Understanding the impact of women's correct risk perception on human immunodeficiency virus diagnosis: Insights from South Africa

BACKGROUND

South African women have the highest burden of HIV infections globally. We investigated the temporal trends and the impact of key factors associated with HIV diagnosis among a nationally representative cohort of South African women.

METHODS

Total of 24,657 women who participated in the National HIV, Behaviour and Health Surveys conducted from 2002-to-2017.

RESULTS

Despite decades-long prevention efforts, we observed a significant increase in HIV prevalence over time (22% in 2002 to 21% in 2005-2008 and 29% in 2012-2017). Overall, 46% of the women living with HIV were not aware of their risk of HIV with age-specific disparities. Our findings revealed compelling evidence between HIV seropositivity and high HIV risk-perception (adjusted Odds Ratio (aOR):1.47 to 3.29) which increased overtime and exceeded the other factors. At a population-level, 45% of the HIV diagnoses were exclusively associated with women who believed they were at risk of HIV in 2012-2017. Women who reported using condoms at last sexual act were also at increased risk of HIV infection, with a population attributable risk of 18% (2002) to 21% (2012-2017).

CONCLUSION

There is an urgent need for culturally, socially, and linguistically appropriate prevention and awareness campaigns with realistic, non-confrontational messages.

How men influence young women taking PrEP: perspectives from young women, male partners, and male peers in Siaya county, Western Kenya

BACKGROUND

Daily oral pre-exposure prophylaxis (PrEP) is an effective HIV prevention option for those who are most vulnerable to HIV infection, especially young women (YW). Objection by or lack of support from male sexual partners has been shown to impact YW's ability to take PrEP consistently. We explored the views of YW, and male partners and male peers of YW in Siaya County, Western Kenya, to illustrate how men influence, and can support, YW in using PrEP.

METHODS

We used Photovoice to capture the views of YW ages 18-24 who were currently or previously enrolled in the DREAMS program and with current or previous experience taking PrEP. We also captured the views of YW's sexual partners and male peers. The YW completed eight photo assignments that focused on identifying factors influencing their PrEP use, and male participants completed four photo assignments focused on identifying ways men support or hinder YW's PrEP use. Photographs were presented and discussed in same- and mixed-gender groups using the SHOWeD method. YW also participated in in-depth interviews. The analysis focused on identifying themes that described men's influence on YW's PrEP adherence and persistence.

RESULTS

Among YW, a restricting male influence on PrEP use emerged in the majority of photo assignments such that YW's photographs and discussions revealed that men were more often viewed as barriers than supporters. YW perceived that they had little autonomy over their sexual lives and choice to use PrEP. YW's PrEP use was perceived to be hindered by stigmatizing community narratives that influenced men's support of PrEP use among women. Male participants suggested that men would support YW's PrEP use if PrEP was better promoted in the community and if men were more knowledgeable about its benefits.

CONCLUSIONS

A lack of support from male partners and peers and stigmatizing community narratives influence YW's PrEP use. Community-based programs should include education about PrEP specifically for male partners and peers of YW to positively influence PrEP use among YW.

Applying the HIV Prevention Cascade to an Evaluation of a Large-Scale Combination HIV Prevention Programme for Adolescent Girls and Young Women in South Africa

Adolescent girls and young women (AGYW) in South Africa are at a three times higher risk of acquiring HIV than their male counterparts. The HIV prevention cascade is a tool which can be used to measure coverage of HIV prevention services, although there is limited empirical evidence to demonstrate its application in low-resourced settings. The unifying framework is a conceptualisation of the HIV prevention cascade which theorises that both motivation and access are required for an individual to effectively use an HIV prevention method. We applied this framework to data from a random sample of 127,951 beneficiaries of a combination HIV prevention programme for AGYW aged 15-24 in South Africa to measure the steps to, and identify key barriers to, effective use of male condoms and oral pre-exposure prophylaxis (PrEP) among this vulnerable population. Barriers to each step were analysed using univariate and multivariable logistic regression. Among self-reported HIV-negative AGYW who had sex in the past 6 months, effective use of condoms (15.2%), access to PrEP (39.1%) and use of PrEP (3.8%) were low. AGYW were: less likely to be motivated to use condoms if they believed that they had a faithful partner (aOR 0.44, 95% CI 0.22-0.90) or disliked condoms (aOR 0.26, 95% CI 0.11-0.57), less likely to access condoms if the place where AGYW accessed them was far away (aOR 0.25, 95% CI 0.10-0.64), more likely to effectively use condoms if they received counselling on how to use them (aOR 2.24, 95% CI 1.05-4.76), less likely to be motivated to use PrEP if they did not believe PrEP was efficacious (aOR 0.35, 95% CI 0.17-0.72), more likely to be motivated if they felt confident that they could use PrEP, and more likely to have access to PrEP if they had ever been offered PrEP (aOR 2.94, 95% CI 1.19-7.22). This combination HIV prevention programme and similar programmes should focus on risk-reduction counselling interventions for AGYW and their male partners to improve effective use of condoms and ensure easy access to condoms and PrEP by making them available in youth-friendly spaces. Our findings demonstrate that the application of HIV prevention cascades can inform AGYW HIV prevention programming in low-resourced settings.

Consanguineous Marriages and the Perception of Wife-Beating Justification in Pakistan: An Application of Fairlie Decomposition Analysis

Pakistan has a significant occurrence of both consanguineous marriages and intimate partner violence (IPV), which may be interlinked. The practice of consanguineous marriages could potentially influence women to rationalize and accept instances of IPV. Such attitudes perpetuate a culture of violence against women, creating difficulties for victims to reject or escape from it. Pakistan has high prevalence rate of consanguineous marriages and IPV. However, no research has been done to explain the difference in acceptance of IPV between women in consanguineous and non-consanguineous marriages. This study used Pakistan Demographic and Health Survey data and applied association tests, logistic regression, and the Fairlie decomposition analysis. The Fairlie decomposition helps us identify the relative contribution of different socioeconomic factors in the inequalities in IPV between the two types of marriages. Five dimensions of wife-beating justification are used as outcome variables. Age, education, and empowerment of women, husband education, woman witness parental violence, region, place of residence, and household wealth status are used as independent variables. The logistic regression results indicated that women in consanguineous marriages of younger age and who witnessed parental violence are more likely to justify wife-beating than those who belong to wealthy households and enjoy more empowerment. Compared to the Punjab province, women residing in Sindh and Baluchistan are less likely and in the Khyber Pakhtunkhwa province are more likely to justify wife-beating. The Fairlie decomposition analysis shows that household wealth status, woman education, and empowerment are the main contributors in explaining the gap between the wife-beating justification of the two groups. The IPV gap can be reduced up to 77% if the distribution of women in different wealth quantiles of the consanguineous marriage group is identical to the non-consanguineous marriage group. Furthermore, woman education level is the second highest contributor. Consanguineous marriages are a prevalent cultural practice in Pakistan and are associated with several negative health and social outcomes. Addressing this issue requires a sustained and comprehensive effort by the government, civil society, and international partners, with a particular focus on women from poor households with less education.

Baiting the hook: Fish scarcity, gendered division of labour, and the fish-for-sex trade

Transactional sex in sub-Saharan Africa's fishing communities, driven by the highly gendered organisation of production, is widely recognised as a key driver of HIV transmission in lakeshore areas. This longitudinal study investigates the economic drivers of the trade and its impact on sexual health outcomes. Specifically, the impact of regional and district fish market shocks and comparable maize shocks on facility-level sexual health outcomes are examined in Tanzania's shoreline communities. Following unfavourable shocks to the fish market, such as high prices or low amounts of fish captured, this paper finds that new HIV cases, newly pregnant women attending antenatal clinic, and the number of people treated for syphilis increases with proximity to the shoreline, supporting the hypothesis that the fish-for-sex trade intensifies when fish supply is relatively scarce. Further, the observed increase in new HIV cases is driven by new cases in women. Contrasting effects are observed following maize price shocks, where facilities see an increase in both male and female new HIV cases following a favourable price shock. These findings highlight the role that gender-based organisation of production plays in shaping sexual health inequalities following shocks to a good.

Pathways to transactional sex among peri-urban South African women: the role of relationship control, food insecurity and alcohol misuse

Transactional sex increases sub-Saharan African women's risk of HIV acquisition. We quantitatively explored the pathways contributing towards women's future engagement in transactional sex with casual partners and khwapheni (secret concurrent sex partners). We conducted secondary data analysis from a cluster randomised controlled trial in urban informal settlements in eThekwini Municipality., South Africa. Data were collected at enrolment (t0) and 24 months' later (t2) using self-completed questionnaires. Structural equation modelling (SEM) assessed pathways leading to transactional sex over two years. 677 women 18-35 years were enrolled and 80.5% (n = 545) were followed up. At t2, 44.6% of respondents reported transactional sex with a casual partner or khwapheni. The SEM demonstrated a small effect (d = 0.23) between transactional sex at t0 and at t2. Controlling for past transactional sex, main partner relationship control had a large effect size on future transactional sex (d = 0.60). Hazardous drinking had a medium effect size (d = 0.45) and food insecurity a small effect (d = 0.24), (RMSEA 0.03, 90%CI 0.02-0.04; CFI 0.97; TLI 0.96). HIV prevention programming should highlight current transactional sex but also address structural issues predicting future transactional sex, including food insecurity and alcohol misuse. Gender transformative interventions to reduce controlling behaviours in main relationships are worth investigating.

Association between water insecurity and antiretroviral therapy adherence among pregnant and postpartum women in Greater Accra region of Ghana

BACKGROUND

Adherence to antiretroviral therapy (ART) can substantially reduce morbidity and mortality among women living with HIV (WLWH) and prevent vertical transmission of HIV. However, in sub-Saharan Africa (SSA), more than 50% of new mothers discontinue ART and HIV care after childbirth. The role of water insecurity (WI) in ART adherence is not well-explored. We examined the relationship between WI and ART adherence among pregnant and postpartum WLWH in Greater Accra region of Ghana.

METHODS

Using a cross-sectional survey, we recruited 176 pregnant and postpartum WLWH on ART across 11 health facilities. We examined the association between WI (measured using the Household Water Insecurity Experience Scale, and categorized as moderate and severe WI compard to low WI) and poor ART adherence (defined as scoring a below average observed CASE index score). Bivariate analysis was performed using chi-square test followed by multivariate logistic regression models. We included all variables with p-values less than 0.20 in the multivariate analysis.

RESULTS

Most (79.5%) of the pregnant and postpartum WLWH enrolled on ART, were urban residents. Over 2/3 were aged 30 years and older. Overall, 33.5% of respondents had poor ART adherence. Proportion of poor ART adherence was 19.4% among those with low WI, 44.4% in those with moderate WI, and 40.0% among those with high WI. Respondents with moderate household water insecurity had a greater odds of reporting poor ART adherence, as compared to those with low water insecurity (adjusted Odds ratio (aOR) = 2.76, 95%CI: 1.14-6.66, p = 0.024), even after adjusting for food insecurity. Similarly, respondents with high WI had a greater odds of reporting poor ART adherence, as compared to those with low water insecurity (aOR = 1.49, 95%CI: 0.50-4.48, p = 0.479), even after adjusting for food insecurity.

CONCLUSION

Water insecurity is prevalent among pregnant and postpartum WLWH and is a significant risk factor for poor ART adherence. Governments and other stakeholders working in HIV care provision should prioritize water security programming for WLWH along the HIV care continuum.

The influence of gender-equitable attitudes on sexual behaviour among unmarried adolescents in rural Tanzania: a longitudinal study

PLAIN LANGUAGE STATEMENT

Gender norms that centre men and disadvantage women create gender inequality, which can lead to risky sexual behaviour. This study examined how both community and individual attitudes toward gender norms influenced risky sexual behaviour in adolescents, and whether that influence was different between males and females. We found that higher gender-equitable attitudes were linked to increased odds of HIV testing in the last 12 months, and decreased odds of engaging in a sexual relationship with a much older partner. Individual high gender-equitable attitudes among girls were also linked to higher odds of them using condoms and contraceptives. Gender-equitable attitudes did not seem to influence early sexual debut, engagement in transactional sex, having multiple sexual partners at the same time, or the number of sexual partners a participant had in the last 12 months. Based on these findings, programming designed to increase gender-equitable attitudes might be helpful in increasing HIV testing and condom and contraceptive use, but it needs to involve the entire community, not just individual boys and girls.

Young women who sell sex in Bangui, Central African Republic: a neglected group highly vulnerable to HIV

BACKGROUND

The objectives of this study were to determine the association between the vulnerability factors linked to human immunodeficiency virus (HIV) and other sexually transmitted infection among the young women who sell sex (YWSS) group (15-24 years) and adult sex workers, engaged in consensual sex for money (AFSW).

METHODS

A cross-sectional study was conducted among AFSW involved in commercial sex transactions. Prevalence ratios (PR) analysis was carried out using log-binomial regression model.

RESULTS

The prevalence of HIV-1 was 29.4% among YWSS compared to 19.6% among female sex worker (PR = 1.43 [1.07-1.91]). Consistent condoms use last 3 months were very low at 22.3% and 41.2%, respectively (PR = 0.52 [0.37-0.74]), the low education level among YWSS versus AFSW (PR = 0.55 [0.40-0.76]); YWSS having been a victim of sexual violence in the last 12 months (PR = 2.00 [1.52-2.63]), were also more likely to be HIV positive.

CONCLUSIONS

The YWSS had a high prevalence of HIV, experienced other socioeconomic vulnerabilities and remain a key population for comprehensive HIV programs. To reach all YWSS, programs need to consider many outreach programs and address the shared determinants of HIV risk.

Depression, Alcohol Use, and Sexual Behaviors by HIV Infection Stage and Diagnosis Timing Among STI Clinic Patients in Lilongwe, Malawi

Understanding depression, alcohol use, and sexual behaviors according to HIV infection stage and diagnosis timing is important for HIV prevention efforts. We enrolled persons with recent infection and diagnosis (i.e., acute HIV infection (AHI) (n = 92) persons newly diagnosed seropositive (n = 360)) and persons previously diagnosed with HIV (n = 190) into a randomized controlled trial in Lilongwe, Malawi (N = 641) and estimated the prevalence of probable depression (Patient Health Questionnaire-9 ≥ 5), hazardous alcohol use (Alcohol Use Disorder Identification Test-C: men ≥ 4; women ≥ 3), and sexual behaviors (transactional sex, condomless sex). Compared with previously diagnosed participants, participants newly seropositive and those with AHI reported a higher proportion of probable depression (7%, 27%, 38%; AHI/Previous: Table Probability: 0.02, p < 0.01; AHI/New: Table Probability: <0.01, p < 0.01), hazardous alcohol use (8%, 18%, 29%; AHI/Previous and AHI/New: Table Probability: <0.01, p < 0.01), and transactional sex (5%, 14%, 20%; AHI/Previous: Table Probability: <0.01, p < 0.01; AHI/New: Table Probability: 0.06, p = 0.24), respectively. HIV prevention services addressing mental health and alcohol misuse may be particularly beneficial for persons with recent HIV infection and or diagnosis.

Small-area estimation and analysis of HIV/AIDS indicators for precise geographical targeting of health interventions in Nigeria. a spatial microsimulation approach

BACKGROUND

Precise geographical targeting is well recognised as an indispensable intervention strategy for achieving many Sustainable Development Goals (SDGs). This is more cogent for health-related goals such as the reduction of the HIV/AIDS pandemic, which exhibits substantial spatial heterogeneity at various spatial scales (including at microscale levels). Despite the dire data limitations in Low and Middle Income Countries (LMICs), it is essential to produce fine-scale estimates of health-related indicators such as HIV/AIDS. Existing small-area estimates (SAEs) incorporate limited synthesis of the spatial and socio-behavioural aspects of the HIV/AIDS pandemic and/or are not adequately grounded in international indicator frameworks for sustainable development initiatives. They are, therefore, of limited policy-relevance, not least because of their inability to provide necessary fine-scale socio-spatial disaggregation of relevant indicators.

METHODS

The current study attempts to overcome these challenges through innovative utilisation of gridded demographic datasets for SAEs as well as the mapping of standard HIV/AIDS indicators in LMICs using spatial microsimulation (SMS).

RESULTS

The result is a spatially enriched synthetic individual-level population of the study area as well as microscale estimates of four standard HIV/AIDS and sexual behaviour indicators. The analysis of these indicators follows similar studies with the added advantage of mapping fine-grained spatial patterns to facilitate precise geographical targeting of relevant interventions. In doing so, the need to explicate socio-spatial variations through proper socioeconomic disaggregation of data is reiterated.

CONCLUSIONS

In addition to creating SAEs of standard health-related indicators from disparate multivariate data, the outputs make it possible to establish more robust links (even at individual levels) with other mesoscale models, thereby enabling spatial analytics to be more responsive to evidence-based policymaking in LMICs. It is hoped that international organisations concerned with producing SDG-related indicators for LMICs move towards SAEs of such metrics using methods like SMS.

An agent-based model of binge drinking, inequitable gender norms and their contribution to HIV transmission, with application to South Africa

BACKGROUND

Binge drinking, inequitable gender norms and sexual risk behaviour are closely interlinked. This study aims to model the potential effect of alcohol counselling interventions (in men and women) and gender-transformative interventions (in men) as strategies to reduce HIV transmission.

METHODS

We developed an agent-based model of HIV and other sexually transmitted infections, allowing for effects of binge drinking on sexual risk behaviour, and effects of inequitable gender norms (in men) on sexual risk behaviour and binge drinking. The model was applied to South Africa and was calibrated using data from randomized controlled trials of alcohol counselling interventions (n = 9) and gender-transformative interventions (n = 4) in sub-Saharan Africa. The model was also calibrated to South African data on alcohol consumption and acceptance of inequitable gender norms. Binge drinking was defined as five or more drinks on a single day, in the last month.

RESULTS

Binge drinking is estimated to be highly prevalent in South Africa (54% in men and 35% in women, in 2021), and over the 2000-2021 period 54% (95% CI: 34-74%) of new HIV infections occurred in binge drinkers. Binge drinking accounted for 6.8% of new HIV infections (0.0-32.1%) over the same period, which was mediated mainly by an effect of binge drinking in women on engaging in casual sex. Inequitable gender norms accounted for 17.5% of incident HIV infections (0.0-68.3%), which was mediated mainly by an effect of inequitable gender norms on male partner concurrency. A multi-session alcohol counselling intervention that reaches all binge drinkers would reduce HIV incidence by 1.2% (0.0-2.5%) over a 5-year period, while a community-based gender-transformative intervention would reduce incidence by 3.2% (0.8-7.2%) or by 7.3% (0.6-21.2%) if there was no waning of intervention impact.

CONCLUSIONS

Although binge drinking and inequitable gender norms contribute substantially to HIV transmission in South Africa, recently-trialled alcohol counselling and gender-transformative interventions are likely to have only modest effects on HIV incidence. Further innovation in developing locally-relevant interventions to address binge drinking and inequitable gender norms is needed.

Understanding the role of intimate partner violence on HIV transmission in Zimbabwe: Secondary data analysis of data from the Zimbabwe demographic survey 2015-2016

Background

Gender-based violence (GBV) has been shown to have significant and long-lasting impacts on women's physical and mental health. It is, therefore, important to study its occurrence in a population and its intersect with infectious diseases such as HIV to inform the wider health promotion agenda. This study aimed to determine the association between GBV and HIV status in women and adolescent girls in Zimbabwe.

Methods

A secondary data analysis of data from a cross-sectional Zimbabwe Demographic and Health Survey (ZDHS) was conducted. Statistical analysis was employed to establish the association between GBV and HIV status. Geospatial mapping was conducted using a kernel smoothing method was employed to generate a continuous kernel density surface to illustrate the local spatial variations of female HIV and GBV prevalence.

Results

Women and adolescent girls suffering emotional GBV, such as those subjected to humiliation by their husbands or partners, were 1.45 (1.14-1.84) [OR (95% CIs)] times more likely to be HIV positive than those who were never humiliated. The same was true for women and adolescent girls whose husbands or partners threatened to harm them or someone they love, 1.33 (1.04-1.68). There is a relationship between women's HIV status and intimate partner aggression, such as when their partners pushed, shook, or threw something at them or physically abused them. This was also the case for those who reported that partners kicked, dragged, or beat them, tried to choke or burn them on purpose, or threatened or attacked them with a knife, gun, or other weapons. Women who experienced forced sexual violence with threats were more likely 1.61 (1.08-2.41), to be HIV positive than those women who did not experience the same.

Conclusion

GBV is widely spread in Zimbabwe. There is a need for the government to implement creative strategies to reach out to survivors, especially those that are forced to have unprotected sex and are at increased risk of HIV acquisition. This manuscript raises issues that can be addressed by robust health promotion strategies to reduce the impact of the syndemic of GBV and HIV acquisition in Zimbabwe.

Development of an Economic and Relationship-Strengthening Intervention for Alcohol Drinkers Living with HIV in Malawi

Heavy alcohol use among people with HIV in sub-Saharan Africa is driven by household economics such as poverty and unemployment and has negative impacts on couple relationships. Multilevel interventions have the potential to reduce alcohol use and improve relationship outcomes by addressing the web of co-occurring economic, social, and dyadic factors. This objective of this study was to develop an economic and relationship-strengthening intervention for couples in Malawi, consisting of matched savings accounts with financial literacy training and a couples counseling component to build relationship skills. Informed by the ADAPT-ITT framework, we collected multiple rounds of focus group data with key stakeholders and couples to gain input on the concept, session content, and procedures, held team meetings with field staff and an international team of researchers to tailor the intervention to couples in Malawi, and refined the intervention manual and components. The results describe a rigorous adaptation process based on the eight steps of ADAPT-ITT, insights gained from formative data and modifications made, and a description of the final intervention to be evaluated in a pilot randomized clinical trial. The economic and relationship-strengthening intervention shows great promise of being feasible, acceptable, and efficacious for couples affected by HIV and heavy alcohol use in Malawi.

Gender differences in HIV knowledge among adolescents and young people in low-and middle-income countries: a systematic review

Objectives

This review seeks to critically analyze studies assessing gender differences in HIV-related knowledge among adolescents and young people in low- and middle-income countries.

Methods

Using PRISMA guidelines and searching Pubmed and Scopus online databases, the search strategy combined search keywords with Boolean operators: (HIV OR AIDS) AND (knowledge) AND (gender) AND (adolescents). AC and EG conducted the search and independently reviewed all articles in Covidence software; conflicts were resolved by GC. Articles were included if they evaluated differences in HIV knowledge in at least two groups ages 10-24 and were implemented in a low or middle-income country.

Results

The search resulted in 4,901 articles, of which fifteen studies, implemented in 15 countries, met selection criteria. Twelve evaluated differences in HIV knowledge in school settings; three evaluated participants in clinic settings. Adolescent males consistently scored higher in composite knowledge scores, as well as knowledge of HIV transmission, prevention, attitudes and sexual decision-making.

Conclusion

We found gender-based discrepancies between knowledge, perception of risk and HIV prevalence among youth globally, with boys consistently scoring higher in HIV knowledge. However, there is significant evidence that social and cultural contexts render girls at high risk of HIV infection, and the gaps in girls' knowledge and boys' roles in HIV risk must be addressed urgently. Future research should consider interventions that facilitate discussion and HIV knowledge building across genders.

When Social and Personal Norms Collide: Narratives of South African Women Navigating Transactional Sexual Relationships with Blessers

Due to the negative implications of transactional sexual relationships (TSRs) for women's sexual and reproductive health, studies of social norms in sub-Saharan and South Africa have sought to inform HIV-related risk and interventions in this key population. To date, however, little research has investigated the normative conflicts facing women in African settings when initiating, continuing or abstaining from participation in TSRs. In 2017-2018, we investigated conflicts black South African women in KwaZulu-Natal expressed between adhering to social versus personal norms in TSRs with "blessers"-wealthy men who gift women financially or materially-typically in exchange for sex. Participants expressed conflicts between social norms of blesser engagement to satisfy aspirations for money/material items vs. personal norms of retaining virginity and fidelity to partners. Women largely ignored adverse sexual health risks of HIV and unintended pregnancy. Participants highlighted internal conflicts, prompting reflection on their desires, choices and normative behaviors, also informing women's self-concept, self-efficacy and desires for relationship satisfaction. Greater reflection from women about personal norms and values-and attention to their self-efficacy in relationships-may assist in understanding and advancing women's holistic health and wellbeing in research and interventions among this population and potentially women in other settings.

Is hope associated with HIV-acquisition risk and intimate partner violence amongst young women and men? A cross-sectional study in urban informal settlements in South Africa

Hope is a concept that may mediate between the structural constraints people live under and their HIV-acquisition risk behaviours/experiences. Drawing on data collected as the baseline for an intervention trial between September 2015 and September 2016, among young (18-30-year-old), out-of-school women and men in urban informal settlements in Durban, South Africa, we assess whether hope, assessed by the Snyder Hope Scale, is associated with HIV-risk behaviours/experiences. 677 women (35.5%; 33.7%; 30.9%; low, medium, and high hope scores respectively) and 668 men (40.6%; 32.8%; 26.7%; low, medium, and high hope scores respectively) were included. Among women, adjusted analyses showed high levels of hope, compared to low levels, were associated with greater modern contraceptive use (aOR1.57, 1.04-2.37). For men, medium or high levels of hope, compared to low levels, were associated with reduced physical and/or sexual IPV perpetration (med: aOR0.55, 0.38-0.81, high: 0.38, 0.25-0.57), emotional IPV perpetration (med: aOR0.54, 0.36-0.80, high: aOR0.62, 0.41-0.94) and transactional sex (med: 0.57, 0.38-0.84, high: aOR0.57, 0.39-0.86) respectively. For men, hope potentially captured a pathway between an individual's structural context and their HIV-risk behaviour. Yet this was not the case for women. It may be the Snyder Hope Scale does not adequately capture localised meanings of hope.

Examining Associations Between Resilience and Sexual Health Among South African Girls and Young Women Living With and Without HIV

Resilience, or multilevel processes related to thriving, offers a strengths-based approach to reducing HIV and sexual risk behaviors among girls and young women. Processes of resilience may change based on the experience of living with HIV. However, little is known about how resilience and serologically verified HIV status influence sexual health. Using weighted cross-sectional data collected during 2017-2018 from South African girls and young women aged 15-24 (N = 7237), this article examines associations between resilience and three sexual risk behaviors among those living with and without HIV. Logistic regression models indicated greater resilience scores were associated with reduced odds of engaging in transactional sex and early sexual debut. Results also identified differing associations between resilience and sexual risk behaviors by HIV status. Findings provide implications for programming to prevent HIV and improve sexual health while underscoring the need for tailored resilience-promoting interventions for South African girls and young women living with HIV.

Assessing risk factors and health impacts across different forms of exchange sex among young women in informal settlements in South Africa: A cross-sectional study

For women in South Africa, engaging in exchange sex, including transactional sex (TS), or sex work (SW), is associated with several shared poor health outcomes; yet the practices themselves differ in meaningful ways. SW is a form of commodity exchange, while TS is grounded in gendered relationship expectations of male provision and aspects of emotional intimacy. Additionally, exchange sex types could be imagined on a "continuum of instrumentality" from relationships that do not include material support; to those characterized, but not driven by support; to those primarily motivated by material support. We use cross-sectional data from 644 women ages 18-30 enrolled in a trial addressing intimate partner violence in urban KwaZulu-Natal, South Africa to assess whether these conceptualizations may also map onto different types or levels of risk. Using self-reports, we developed four exchange sex relationship categories corresponding to a continuum of instrumentality: no exchange-based relationship; TS with a main partner only; TS with a casual partner; and SW. Using tests of association and adjusted logistic regression models, we compared socio-economic and behavioural risk factors, and health outcomes across reported forms of exchange sex. We find little difference between women who report no exchange sex and those who report TS only with a main partner. By contrast, as compared to women not in exchange sex, women in casual TS and SW were poorer, and significantly more likely to report problematic alcohol use, past drug use, prior non-partner sexual violence, and PTSD; with aOR higher for women in SW for many outcomes. When comparing casual TS to SW, we find women in SW held more gender equitable attitudes and were more likely to report modern contraceptive use. We discuss the implications for distinguishing between TS and SW, and use of the continuum of instrumentality conceptualization for research and programming.

A Prospective Analysis of the Interrelationship between Physical Intimate Partner Violence and Alcohol Use: A Post-Hoc Analysis of Young Women Involved in the Stepping Stones and Creating Futures Trial in South Africa

Prospective studies assessing women's experience of intimate partner violence (IPV) and alcohol use have shown mixed results and all are from high-income countries. Using longitudinal data from young women in South Africa we assess whether changes in physical IPV impact alcohol use, and whether changes in alcohol use impact physical IPV experience. Post-hoc analysis of women aged 18-30 living in informal settlements in eThekwini Municipality, South Africa, involved in the Stepping Stones and Creating Futures trial, between September 2015 and October 2019, with data collected at baseline (n = 677) and endline at 24 months (n = 545, 80.5% retention). At both timepoints, women were asked about their past year physical IPV experience and alcohol use. We estimated changes in physical IPV over time and whether this was associated with harmful alcohol use at endline. We then estimated changes in alcohol use over time, and whether this was associated with experience of past year physical IPV at endline. Women who experienced an increase in physical IPV over the study period were more likely to report harmful drinking at 24 months (aOR2.45, 95% CI 1.21-4.97). Similarly, women reporting increased alcohol use over time were more likely to report past year physical IPV at 24 months (aOR2.04, 95% CI 1.21-3.46). Among young women living in urban poverty those who experienced increasing physical violence from intimate partners were more likely to report increased and problematic alcohol use. Similarly, women reporting increasing alcohol use over 24 months were more likely to report physical IPV. However, there was no evidence that decreased alcohol use led to reductions in IPV, or that reduced IPV experience led to decreased alcohol use. Future research and interventions need to consider the reciprocal risks of physical IPV and alcohol use, with a focus on joint underlying drivers.

Utility of a machine-guided tool for assessing risk behaviour associated with contracting HIV in three sites in South Africa

Introduction

Digital data collection and the associated mobile health technologies have allowed for the recent exploration of artificial intelligence as a tool for combatting the HIV epidemic. Machine learning has been found to be useful both in HIV risk prediction and as a decision support tool for guiding pre-exposure prophylaxis (PrEP) treatment. This paper reports data from two sequential studies evaluating the viability of using machine learning to predict the susceptibility of adults to HIV infection using responses from a digital survey deployed in a high burden, low-resource setting.

Methods

1036 and 593 participants were recruited across two trials. The first trial was a cross-sectional study in one location and the second trial was a cohort study across three trial sites. The data from the studies were merged, partitioned using standard techniques, and then used to train and evaluate multiple different machine learning models and select and evaluate a final model. Variable importance estimates were calculated using the PIMP and SHAP methodologies.

Results

Characteristics associated with HIV were consistent across both studies. Overall, HIV positive patients had a higher median age (34 [IQR: 29-39] vs 26 [IQR 22-33], p < 0.001), and were more likely to be female (155/703 [22%] vs 107/927 [12%], p < 0.001). HIV positive participants also had more commonly gone a year or more since their last HIV test (183/262 [70%] vs 540/1368 [39%], p < 0.001) and were less likely to report consistent condom usage (113/262 [43%] vs 758/1368 [55%], p < 0.001). Patients who reported TB symptoms were more likely to be HIV positive. The trained models had accuracy values (AUROCs) ranging from 78.5% to 82.8%. A boosted tree model performed best with a sensitivity of 84% (95% CI 72-92), specificity of 71% (95% CI 67-76), and a negative predictive value of 95% (95% CI 93-96) in a hold-out dataset. Age, duration since last HIV test, and number of male sexual partners were consistently three of the four most important variables across both variable importance estimates.

Conclusions

This study has highlighted the synergies present between mobile health and machine learning in HIV. It has been demonstrated that a viable ML model can be built using digital survey data from an low-middle income setting with potential utility in directing health resources.

'I was in need of somewhere to release my hurt:' Addressing the mental health of vulnerable adolescent mothers in Harare, Zimbabwe, through self-help groups

Background

Adolescents experiencing multiple vulnerabilities, including poverty, curtailed education, transactional sex and early childbearing, are at risk of poor mental health. In Zimbabwe, girls who are pregnant or new mothers and involved in selling sex struggle to cope with the combined pressures of parenthood, financial insecurity, and social stigma. A pilot intervention brought such girls together into self-help groups to increase peer support, resources and skills.

Objective

This study aimed to explore whether and how participation in a self-help group intervention affected vulnerable young mothers’ experiences and perceptions of mental health stressors.

Methods

Self-help groups received 12 participatory sessions over 6 months. Eighteen semi-structured interviews and three focus group discussions were held with participants and drop-outs. Before and after the intervention, participants completed the locally validated 14-item Shona Symptom Questionnaire tool to indicate the probable prevalence of common mental health disorders.

Results

Adolescent girls described mutually reinforcing stressors in their lives and reported low self-esteem and anxiety. Key themes emerging from qualitative data centred around girls’ struggles with adverse life events, the burden of new motherhood, social isolation related to sex work and self-help groups as a source of hope. Participants joined groups to obtain support and felt their mental well-being improved due to new social networks, feelings of solidarity with peers, and increased confidence for positive action, that is, seeking health services for themselves and their babies. Prior to enrolment 16% showed signs of possible common mental disorders falling to 2% at follow-up.

Conclusions

Participants believed involvement in interactive self-help groups improved their mental health by strengthening peer support and engendering hope for the future. Although reduced mental distress cannot be attributed to the programme, the pilot intervention offers a low-cost approach that could be rigorously tested and adapted to a wide range of community settings.

Sexual and reproductive health and rights knowledge, perceptions, and experiences of adolescent learners from three South African townships: qualitative findings from the Girls Achieve Power (GAP Year) Trial

Background: Adolescence is a time of psycho-social and physiological changes, with increased associated health risks including vulnerability to pregnancy, HIV, sexually transmitted infections, and gender-based violence. Adolescent learners, from three townships in South Africa, participated in a 44 session, after-school asset-building intervention (GAP Year), over 2 years providing sexual and reproductive health (SRH) education. This paper explores adolescent learners' SRH, sexual risk and rights knowledge; perceptions about transactional sex; and contraceptive method preferences and decision-making practices. Methods: The intervention was conducted in 13 secondary schools across Khayelitsha, Thembisa, and Soweto, South Africa. A baseline survey collected socio-demographic data prior to the intervention. Overall, 26 focus group discussions (FGDs): 13 male and 13 female learner groups, purposively selected from schools, after completing the intervention (2 years after baseline data collection). Descriptive analyses were conducted on baseline data. Qualitative data were thematically coded, and NVivo was used for data analysis. Results: In total, 194 learners participated in the FGDs. Mean age at baseline was 13.7 years (standard deviation 0.91). Participants acquired SRH and rights knowledge during the GAP Year intervention. Although transactional sex was viewed as risky, some relationships were deemed beneficial and necessary for material gain. Negative healthcare provider attitudes were the main barrier to healthcare service utilisation. There was awareness about the benefits of contraceptives, but some myths about method use. The injectable was the preferred contraceptive method, followed by the implant, with equal preference for condoms and oral pill. Conclusions : An afterschool intervention at school is a viable model for the provision of SRH and rights education to learners. Recommendations include the need for risk reduction strategies in the curriculum, dealing with misconceptions, and the promotion of informed decision making. Endeavours to ensure health services are youth friendly is a priority to limit barriers to accessing these services.

Transactional sex among adolescent girls and young women enrolled in a cash plus intervention in rural Tanzania: a mixed-methods study

INTRODUCTION

Transactional sex or material exchange for sex is associated with HIV infection among adolescent girls and young women in sub-Saharan Africa. The motivations for engaging in transactional sex vary from the fulfilment of basic needs, to enhancing social status or for romantic reasons with the expectation that men should provide. Transactional sex is also associated with HIV risk behaviours, such as multiple sexual partners and other determinants of HIV risk, including partner violence and abuse, alcohol consumption and inconsistent condom use.

METHODS

We use data from a mixed-method, cluster randomised controlled trial of the Ujana Salama cash "plus" intervention in rural Tanzania. The data are from the first and third rounds of data collection (2017-2019). The impact evaluation consisted of a parallel mixed-methods design where the quantitative and qualitative data collection occurred simultaneously, and integration of the findings was done during the discussion. We first examine contextual factors associated with transactional sex using multivariable logistic regression models and then estimate whether the "plus" intervention reduced transactional sex among adolescent girls and young women using analysis of covariance. We used thematic content analysis for analysing qualitative transcripts.

RESULTS

The prevalence of transactional sex among unmarried adolescent girls and young women at round 3 was 26%. Findings show that increasing age is a risk factor for transactional sex (OR = 1.80; 95% CI: [1.50, 2.17]), staying in school was negatively associated with engagement in transactional sex (OR = 0.24; 95% CI: [0.14, 0.40]). The cash plus intervention showed no impacts on reducing transactional sex (β = 0.003, p = 0.905).

CONCLUSIONS

The mechanisms of impact for a cash plus intervention on transactional sex are complex; economic insecurity is an important driver of transactional sex and HIV infection, but psychosocial factors and gendered social norms need consideration in intervention development. Our findings suggest that combination prevention interventions to address the structural drivers of HIV infection should focus on efforts to increase school enrolment and completion.

From a drought to HIV: An analysis of the effect of droughts on transactional sex and sexually transmitted infections in Malawi

Each year there are over 300 natural disasters globally with millions of victims that cost economic losses near USD$100 billion. In the context of climate change, an emerging literature linking extreme weather events to HIV infections suggests that efforts to control the HIV epidemic could be under threat. We used Demographic and Health Survey (DHS) data collected during the 2015-2016 harsh drought that affected several areas of Malawi to provide new evidence on the effect of an unanticipated economic shock on sexual behaviours of young women and men. We find that amongst women employed in agriculture, a six-months drought doubles their likelihood of engaging in transactional sex compared to women who were not affected by the drought and increases their likelihood of having a sexually transmitted infections (STI) by 48% in the past twelve months. Amongst men employed outside of agriculture, drought increases by 50% the likelihood of having a relationship with a woman engaged in transactional sex. These results suggest that women in agriculture experiencing economic shocks as a result of drought use transactional sex with unaffected men, i.e. men employed outside agriculture, as a coping mechanism, exposing themselves to the risk of contracting HIV. The effect was especially observed among non-educated women. A single drought in the last five years increases HIV prevalence in Malawi by around 15% amongst men and women. Overall, the results confirm that weather shocks are important drivers of risky sexual behaviours of young women relying on agriculture in Africa. Further research is needed to investigate the most adequate formal shock-coping strategies to be implemented in order to limit the negative consequences of natural disasters on HIV acquisition and transmission.

"The sky is the limit; I am going there": experiences of hope among young women receiving a conditional cash transfer in rural South Africa

Young women in South Africa face elevated risk of HIV infection compared to male peers. Cash transfers may mitigate their risk for HIV; however, there is limited understanding of mechanisms of impact. We explored hope as one potential mechanism. Longitudinal qualitative analysis was used to explore how cash transfer recipients in the HPTN 068 study conceptualised hope and how the intervention influenced their hope over time. We found the intervention increased confidence, alleviated financial stressors and instilled in young women the belief that a better life, defined as being educated, independent and supportive to family, was attainable. Findings support hope as a critical outcome of cash transfer and other economic strengthening interventions.

"A man without money getting a sexual partner? It doesn't exist in our community": male partners' perspectives on transactional sexual relationships in Uganda and Eswatini

Research on transactional sexual relationships has largely focused on women's perspectives. Better understanding the men's views-especially regarding relationships with adolescent girls and young women-can inform HIV prevention efforts. In 2017, 134 in-depth interviews were conducted with the male partners of girls and young women aged 19-47 years, 94 in Uganda and 40 in Eswatini. Respondents were recruited at venues such as bars where men and potential partners meet and through other young women. Most respondents believed that providing money/gifts was the way to establish relationships with women in their communities, a context that some found undesirable. Young women were mainly perceived as actively pursuing transactional sex for material goods, but respondents also described economically impoverished women who were manipulated into relationships. Men described conflict with longer term partners as a driver to seeking younger partners, who were more compliant. Transaction dominates the male partners of adolescent girls and young women's understanding of sexual relationships, and inequitable power dynamics are reinforced by seeking younger partners. However, some respondents' discontent with this dynamic suggests an opportunity for change. HIV prevention programmes should directly address the underlying drivers of transactional relationships (e.g. gender norms) and work with men who question the practice.

Women's Economic Contribution, Relationship Status and Risky Sexual Behaviours: A Cross-Sectional Analysis from a Microfinance-Plus Programme in Rural South Africa

In sub-Saharan Africa, women bear a disproportionate burden of HIV/AIDS while also facing economic and gender inequalities. To explore the association of women’s economic contribution and relationship status with risky sexual behaviour, this study analysed cross-sectional data from 626 women aged 22 to 84 in rural South Africa. All women were enrolled in a microfinance plus gender training programme (Intervention with Microfinance for AIDS and Gender Equity (IMAGE)). We used univariable and multivariable logistic regression to explore the associations of relationship status and women’s household income contribution with inconsistent condom use, multiple sexual partners and transactional sex, respectively. We found that married, older women had the highest odds of inconsistent condom use, while those contributing all the household income had higher odds of multiple sexual partnerships, but lower odds of transactional sex compared to those with no contribution. Income contribution and relationship status have a nuanced relationship with sexual risk behaviours. Thus, economic strengthening interventions should target relevant vulnerable women while also addressing the broader social and economic drivers of risky sexual behaviour.

Emotional Violence is Associated with Increased HIV Risk Behavior Among South African Adolescent Girls and Young Women in the HPTN 068 Cohort

Limited research has explored how emotional intimate partner violence (IPV) shapes HIV risk behaviors. Using cross-sectional data from the HPTN 068 post-trial visit (N = 1942), we assessed the association between emotional IPV and its sub-domains (verbal abuse and threats) with condomless sex, transactional sex, and frequent alcohol use among young women in South Africa. In adjusted multivariable logistic regression models, any emotional IPV and verbal IPV were associated with increased odds of condomless sex (aOR: 1.47; 95% CI: 1.15, 1.87; and aOR: 1.48; 95% CI: 1.15, 1.89), transactional sex (aOR: 2.32; 95% CI: 1.74, 3.08; and aOR: 2.02; 95% CI: 1.51, 2.71) and alcohol use (aOR: 1.88; 95% CI: 1.39, 2.53; and aOR: 1.87; 95% CI: 1.37, 2.55). Threats were associated with transactional sex (aOR: 3.67; 95% CI: 2.62, 5.14). Future research should examine this relationship over-time and HIV prevention programs should consider and address emotional IPV.

The role of education and income as protective factors against intimate partner violence and HIV exposure among Kenyan women

Introduction

Intimate partner violence (IPV) is a public health problem that impacts approximately one in three women worldwide in their life-time. The purpose of the study was to explore the lived experiences of women teachers and violence in Kenya. It also explores the intersection between intimate partner violence, HIV risk, and gender inequality.

Method

Data were collected through two focus groups of a total of 15 women teachers. We recruited women ages 21-44 from two geographically diverse urban and rural schools. The data were analyzed using a thematic analysis method to identify text themes and meaning patterns.

Results

Three contextual experiences emerged: socio-cultural influences of gender norms, masculinity and patriarchy; uneven power dynamics; and institutionalized gender inequality.

Discussion

Findings suggest that education alone is not sufficient to end GBV. Comprehensive and gender transformative governmental policy approaches are needed to mitigate GBV in Kenya.

Sexual and reproductive health and rights knowledge, perceptions, and experiences of adolescent learners from three South African townships: qualitative findings from the Girls Achieve Power (GAP Year) Trial

Background: Adolescence is a time of psycho-social and physiological changes, with increased associated health risks including vulnerability to pregnancy, HIV, sexually transmitted infections, and gender-based violence. Adolescent learners, from three townships in South Africa, participated in a 44 session, after-school asset-building intervention (GAP Year), over 2 years providing sexual and reproductive health (SRH) education. This paper explores adolescent learners’ SRH, sexual risk and rights knowledge; perceptions about transactional sex; and contraceptive method preferences and decision-making practices.

Recommendations include the need for risk reduction strategies in the curriculum, dealing with misconceptions, and the promotion of informed decision making. Endeavours to ensure health services are youth friendly is a priority to limit barriers to accessing these services.

Impact of marital status on risk of HIV in South Africa (2002-2017)

After decades of research, South African women continue to have the highest burden of HIV in the world. The aim of the study is to investigate the impact of marital status on HIV using population and community-level data sources. We included data 13,469 and 5682 South African women who participated to South African HIV behavioural surveys in 2002-2012 and 2017, respectively. HIV prevalence and incidence rates were significantly higher among single/not-cohabiting women compared to those married/cohabiting with a partner in all survey participants (adjusted odds ratio (aOR): 1.60 and 1.58 in 2002-2012 and 2017, respectively). A quarter of the HIV diagnoses were attributed to those who were single/not-cohabiting women (population attributable risk (PAR%): 25% and 24%, respectively). More than 40% of the HIV infections were exclusively associated with single women (PAR%: 42%, 95% CI: 33%, 51%). Our results provided strong evidence for the profound impact of marital status on excess HIV infection rates. Targeting and reaching single/not-cohabiting women with multiple risk factors can potentially play a crucial role in the trajectories of the epidemic.

Sex work and young women: a cross sectional study to understand the overlap of age and sex work as a central tenet to epidemic control in South Africa

Adolescent girls and young women (AGYW) engaging in sex-for-money transactions are at risk of HIV infection. A better understanding of the demographic, socio-economic factors and risks of HIV acquisition is required to guide appropriate public health interventions targeting young sex workers in South Africa. A cross-sectional survey of Female Sex Workers (FSWs), using a chain referral sampling method, was conducted across 12 sites in South Africa in 2019. Three thousand and five participants were enrolled and interviewed assessing demographic characteristics, sexual behaviour, substance use and HIV testing and treatment. Of 3005 women, 13.3% were ≤24 years old (young FSWs); of these, 60.0% entered sex work aged ≤19 years. Economic factors were the primary drivers of entry into sex work. HIV prevalence amongst young FSWs was 40.4%, with 12.4% recently infected. Younger FSWs were significantly less likely to know they were HIV positive (87.6% versus 92.1%), to report any ART exposure (75.2% versus 87.6%) and to be virally suppressed (58.1% versus 75.2%) compared to older FSWs. Our findings highlight that many FSWs enter sex work at a young age. It is essential to develop tailored services and interventions that improve access to HIV prevention and treatment services addressing specific needs.

Individual and Relationship-Level Correlates of Transactional Sex Among Adolescent Girls and Young Women in Malawi: A Multilevel Analysis

Transactional sex increases HIV risk among adolescent girls and young women (AGYW). Understanding the individual and dyadic nature of transactional sex may provide evidence for risk reduction interventions. Multilevel logistic regression was used to cross-sectionally examine correlates of transactional sex among AGYW in Lilongwe, Malawi. Participants (N = 920) reported 1227 relationships. Individual-level associations were found between being divorced/widowed (AOR 5.07, 95% CI 1.93, 13.25), married (AOR 0.26, 95% CI 0.09, 0.72), or unstably housed (AOR 7.11, 95% CI 2.74, 18.47) and transactional sex. At the relationship-level, transactional sex occurred in relationships with: non-primary primary partners (AOR 4.06, 95% CI 2.37, 6.94), perceived partner concurrency (AOR 1.85, 95% CI 1.11, 3.08), and feared violence with couples HIV testing (AOR 2.81, 95% CI 1.26, 6.29), and less likely to occur in relationships with children (AOR 0.15, 95% CI 0.06, 0.38). Multiple co-occurring social and structural vulnerabilities increase transactional sex engagement warranting the need for social protection and gender transformative approaches.

Adolescent girls' perceived readiness for sex in Central Uganda - liminal transitions and implications for sexual and reproductive health interventions

Young women in Uganda are at risk of negative sexual and reproductive health outcomes, in part because of sex with older men. Theoretically grounded in the concept of liminality, this paper examines perceived markers of adolescent girls' suitability for sexual activity. In 2014, we conducted 19 focus group discussions and 44 in-depth interviews in two communities in Uganda. Interviews were conducted using a semi-structured tool, audio-recorded and transcribed verbatim. Interviews examined markers of transition between childhood, adolescence and adulthood and how these were seen as relating to girls' perceived readiness for sex. Analysis was thematic. Pre-liminal status was most often accorded to childhood. Sex with a child was strongly condemned. Physical changes during puberty and children's increasing responsibility, autonomy and awakening sexuality reflected a liminal stage during which girls and young women were not necessarily seen as children and were increasingly described as suitable for sex. Being over 18, leaving home, and occupying 'adult' spaces reflected post-liminal status and perceived appropriateness for sexual activity including for girls under the age of 18. Interventions that seek to prevent early sexual debut and sexual activity with older men have the potential to reduce sexual and reproductive health risks.

Antiretroviral therapy based HIV prevention targeting young women who sell sex: a mixed method approach to understand the implementation of PrEP in a rural area of KwaZulu-Natal, South Africa

Pre-Exposure Prophylaxis (PrEP) is a potential game-changer for HIV. We used PrEP introduction for Young Women Who Sell Sex (YWSS) in a rural South Africa district to understand community norms and PrEP coverage in YWSS. Between 2017 and 2018, we measured awareness and uptake of PrEP in a representative cohort of 2184 Adolescent Girls and Young Women (AGYW) aged 13-22. We conducted group discussions with young people and community members (19); key informant interviews (9), in-depth interviews with 15-24 year-olds (58) and providers (33). Interviews were analysed using thematic analysis. PrEP awareness increased from 2% to 9%. Among 965 AGYW sexually-active by 2018, 13.4% (95%CI: 11.4%-15.7%) reported transactional sex and 10.6% (95%CI: 8.85-12.7%) sex for money. Of the 194 YWSS, 21 were aware of PrEP, but none had used it. Youth were enthusiastic about PrEP as tool for HIV prevention; whilst older community members were cautious about a technology they had limited experience with but could benefit select groups. Teachers and healthcare providers were concerned that PrEP would lower personal responsibility for sexual health. In conclusion, the narrow and limited introduction of PrEP to YWSS reduced the accessibility and reach. Introducing PrEP as part of sexual healthcare may improve demand and access for YWSS.

Temporal shifts in HIV-related risk factors among cohorts of adolescent girls and young women enrolled in DREAMS programming: evidence from Kenya, Malawi and Zambia

OBJECTIVES

To assess temporal shifts in HIV risk factors among adolescent girls (AG, aged 15-19 years) and young women (YW, aged 20-24 years) in Kenya, Malawi and Zambia.

DESIGN

Prospective cohorts with two time points (Kenya: 2016/2017, 2018; Malawi: 2017, 2018; Zambia: 2016/2017, 2018) SETTING: Community-based programming.

PARTICIPANTS

1247 AG (Kenya: 389, Malawi: 371, Zambia: 487) and 1628 YW (Kenya: 347, Malawi: 883, Zambia: 398) INTERVENTION: Determined, Resilient, Empowered, AIDS-free, Mentored and Safe (DREAMS), a multisectoral approach to reduce AGYW's HIV vulnerability by delivering a package of tailored, multilayered activities and services.Primary and secondary outcome measures: HIV testing, sexually transmitted infection (STI) symptom experience, number of sexual partners, condom use (consistently, at last sex), transactional sex, experience of physical violence (from intimate partners) and sexual violence (from intimate partners and strangers/non-partners).

RESULTS

Changes in HIV-related risk behaviours among DREAMS participants varied by age group and country. Among AG, HIV testing increased (Kenya and Zambia) and sexual violence from partners (in Kenya and Malawi) and non-partners (in Malawi) decreased. Among YW, HIV testing increased and STI experience decreased in Malawi; consistent condom use decreased in Kenya; transactional sex increased in Kenya and Zambia; and physical violence (in Malawi) and sexual violence from partners (in Kenya and Malawi) and non-partners (all three countries) decreased over time.

CONCLUSIONS

Improvements in HIV testing and reductions in experiences of sexual violence were coupled with variable shifts in HIV-related risk behaviours among DREAMS participants in Kenya, Malawi and Zambia. Additional consideration of AGYW's risk circumstances during key life transitions may be needed to address the risk heterogeneity among AG and YW across different contexts.

Prevalence of risk factors for human immunodeficiency virus among women of reproductive age in Sierra Leone: a 2019 nationwide survey

Background and aim

For over 40 years of the HIV/AIDS global epidemic, no effective cure nor vaccine is yet available, making the current control strategies focused on curbing new infections through risk reduction. The study aimed to determine the prevalence of HIV risk factors and their associated socio-demographics among women of reproductive age in Sierra Leone.

Methods

We used weighted data from the Sierra Leone Demographic and Health Survey (SLDHS) of 2019 for 12,005 women aged 15–49 years. Multistage sampling was used to select study participants. Exposure to HIV risk factors was considered if a woman reported at least one of the following; having multiple sexual partners, transactional sex, non-condom use for the unmarried, and having other sexually transmitted infections (STIs). We, then, conducted multivariable logistic regression to explore the associated socio-demographics. All the analyses were done using SPSS (version 25).

Results

Of the 12,005 women, 38.1% (4577/12005) (95% confidence interval (CI) 37.3–39.0) had at least one of the four risk factors. Women of 15 to 19 years (adjusted odds ratio (AOR) = 1.34, 95% CI 1.00–1.80) and 20 to 34 years (AOR = 1.25, 95% CI 1.05–1.49) had more odds of having HIV risk factors compared to those of 35 to 49 years. Urban residents (AOR = 1.49, 95% CI 1.17–1.89) and those from the Northwestern region (AOR = 1.81, 95% CI 1.26–2.60) were also more likely to encounter HIV risk factors compared to their respective counterparts. Moreover, unmarried women (AOR = 111.17, 95% CI 87.55–141.18) and those working (AOR = 1.38, 95% CI 1.14–1.67) also had higher odds of having HIV risk factors, compared to their respective counterparts. Sex of household head and parity were also significant associates.

Conclusions

More than a third of women in Sierra Leone had encountered at least one HIV risk factor, and this was associated with age, place of residence, region, marital status, working status, household head and parity.

Factors associated with female students' past year experience of sexual violence in South African public higher education settings: A cross-sectional study

BACKGROUND

Intimate partner sexual violence and non-partner rape experiences are widely reported by female students in South African higher education institutions, as they are globally. However, limited research has focused on investigating vulnerability factors, which is vital for informing interventions.

OBJECTIVE

To describe the factors and inter-relationships associated with female students' increased vulnerability to past year experience of partner sexual violence and non-partner rape in South African higher education settings.

METHODS

We interviewed 1293 female students, i.e., 519 students in six Technical Vocational Education and Training (TVET) college campuses and 774 students at three university campuses. Participants were volunteers aged 18-30. The measured vulnerability factors included childhood sexual abuse, other trauma, mental ill-health, risky sexual behaviours, food insecurity, partner violence, and controlling behaviours. We used bivariate analysis, logistic regression, and structural equation modelling methods.

RESULTS

Twenty percent of participants experienced past-year sexual violence (17% partner sexual violence and 7.5% non-partner rape). Childhood sexual abuse had direct effects on experiencing past year sexual violence and physical, emotional partner violence or controlling behaviours. Risky sexual behaviours mediated the relationships of childhood sexual abuse or harmful alcohol use and past-year sexual violence experience. Mental ill-health mediated the relationships between childhood sexual abuse, other traumatic exposures, food insecurity, physical, emotional partner violence or controlling behaviours, and past-year partner sexual violence or non-partner rape experience.

CONCLUSIONS

Risky sexual behaviours, gender inequitable relationship dynamics, mental ill-health, and food insecurity are related and amenable vulnerability factors associated with female students' sexual violence experiences. Therefore, addressing these through comprehensive campus interventions, which are implemented when students first enrol in higher education and are most vulnerable to sexual violence, is critical. Society-wide sexual violence prevention is also imperative.

Measuring transactional sex in different contexts: How do tools to measure this practice perform in rural South Africa?

Background: Adolescent girls and young women across sub-Saharan Africa are at disproportionate risk of HIV infection compared to their male counterparts. Transactional sex has been identified as an important proximate risk for infection in this population. Definitions and measures of transactional sex vary, necessitating improved measures to better estimate prevalence across settings, over time, and to understand the mechanisms through which transactional sex increases HIV risk. This article describes the results of cognitive interviews in rural KwaZulu-Natal in South Africa to evaluate the performance of an improved measure of transactional sex.Methods: Data were collected between May and June 2017 with sexually active adolescent girls and young women (n = 10) and men (n = 10) drawn from a general population sample. Two questions were tested. Audio-recorded interviews were conducted in isiZulu using a structured tool. Matrices were used to summarise the data across participants which were then compared using constant comparative techniques.Results: Participants captured the instrumental nature of transactional sex relationships clearly and understood that the questions were about relationships that were primarily motivated by benefit. However, despite prior qualitative research in this setting describing transactional sex as widely practised, only one male participant answered either question in the affirmative in this face-to-face interview. This implies a judgement placed on relationships that are deemed as having been motivated mainly by exchange, perhaps compelling people to under-report such relationships.Conclusion: Participants' unwillingness to answer in the affirmative highlights the importance of understanding the research context and the possible social and historical influences which may influence how survey questions are answered. This has implications for measurement development, and highlights the need for measures that can be responsive to contextual differences. Further research is needed for refinements to measurement approaches in this and other settings.

Association of intimate partner violence and other risk factors with HIV infection among married women in India: evidence from National Family Health Survey 2015-16

Background

Human immunodeficiency virus (HIV) infection remains an important public health concern in many countries. It is fuelled by gender inequality and disparity, which has resulted in a fundamental violation of women’s human rights. This study aims to find out the association of intimate partner violence (IPV) and other risk factors with the prevalence of HIV infection among married women in India.

Methods

This study is based on data from the India National Family Health Survey (2015–16). Bivariate analysis has been performed to estimate the prevalence of HIV. Logistic regression analysis is conducted to find out the association between IPV, factors such as having alcoholic husband and lifetime partner, and HIV infection among currently married women.

Results

Married women who had faced physical, sexual, and emotional violence from their husbands/partners were almost twice more likely to have tested HIV positive compared to married women who did not face violence [OR: 2.14, CI: 1.08–4.50]. The odds of testing for HIV positive was significantly higher among the married women experiencing IPV and having alcoholic husband [OR: 4.48, CI: 1.87–10.70] than those who did not experience IPV and had non-alcoholic husband. The use of condom did not show any significant association with HIV infection. Again, having more than one lifetime partner had a positive association with HIV infection compared to those with one partner [OR: 2.45, CI: 1.21–4.16].

Conclusions

The study revealed that factors such as experiencing all types of IPV, having an alcoholic husband, increased number of lifetime partners, being sexually inactive, belonging to vulnerable social groups, and urban place of residence are important risk factors of HIV infection among married women in India. The results also suggest that gender-based violence and an alcoholic husband may represent a significant factor of HIV infection among married women and interventions should on focus such vulnerable populations.

Regional heterogeneity in violence and individual characteristics associated with recent transactional sex among Ugandan girls and young women: A national and regional analysis of data from the Violence Against Children and Youth Survey

Objectives

This study assessed associations between recent transactional sex (TS) and potential determinants and variations in patterns across two geographic regions with high HIV burden compared to the rest of Uganda, among adolescent girls and young women (AGYW).

Methods

In 2015, a nationally representative cross-sectional household survey was conducted in Uganda. A stratified multi-stage cluster sample design produced nationally representative estimates and sub-national estimates for AGYW in two high HIV burden regions, DREAMS Central 1 (Bukomansimbi, Ssembabule, and Rakai districts) and DREAMS Central 2 (Mubende, Mityana, Gomba, and Mukono districts), and the rest of Uganda. To identify associations between recent TS (defined as sex in the past 12 months in exchange for material support or help) and risk factors, multivariable logistic regressions were conducted. Interaction terms assessed the associations between violence and recent TS across geographic regions.

Results

Nationally, 14.2% of sexually active AGYW engaged in recent TS. Region-specific significant associations emerged between recent TS and marriage, family wealth, friendship, orphanhood, and sexual debut. In DREAMS Central 1 and 2, AGYW who witnessed violence in the home or community, or experienced sexual, physical, or emotional violence had higher odds of recent TS than AGYW who did not experience that form of violence (adjusted odds ratio ranged between 2.10 (95% CI, 1.07, 4.13) and 8.25 (95% CI, 3.40, 20.06)). The magnitude of association between recent TS and types of violence varied by region.

Conclusions

Violence is strongly and consistently associated with recent TS, and patterns in prevalence and risk factors vary across regions in Uganda. Given the high risk of HIV association with recent TS, HIV epidemic control efforts may benefit from focus on comprehensive violence prevention and target persons who engage in TS. Comprehensive HIV prevention programming aimed at keeping AGYW HIV-negative should incorporate prevention of violence and TS as key components to facilitate HIV epidemic control in this vulnerable population.

Supplemental Nutrition Assistance Program Eligibility and HIV Incidence in the United States

Background

The connection between food insecurity and HIV outcomes is well established. The Supplemental Nutrition Assistance Program (SNAP), the primary food safety net program in the United States, may have collateral impacts on HIV incidence. “Broad-based categorical eligibility” for SNAP is a policy that provides a mechanism for states to increase the income or asset limits for SNAP eligibility.

Methods

We estimated the association between the number of new HIV diagnoses in 2010–2014 for each state and (1) state income limits and (2) state asset limits for SNAP eligibility. We fitted multivariable negative binomial regression models with number of HIV diagnoses specified as the outcome; SNAP policies as the primary explanatory variable of interest; state and year fixed effects; and time-varying covariates related to the costs of food, health care, housing, employment, other SNAP policies, and Temporary Assistance for Needy Families spending.

Results

HIV diagnoses within states had a statistically significant association with state income limits for SNAP eligibility (incidence rate ratio [IRR], 0.94 per increase in the income limit by 35% of federal poverty level; 95% CI, 0.91–0.98), but no association with state asset limits (increased asset limit vs no change: IRR, 1.02; 95% CI, 0.94–1.10; eliminated asset limit vs no change: IRR, 1.04; 95% CI, 0.99–1.10).

Conclusions

State income limits for SNAP eligibility were inversely associated with the number of new HIV diagnoses for states between 2010 and 2014. Proposals to eliminate the use of broad-based categorical eligibility to increase the income limit for SNAP may undercut efforts to end the HIV epidemic in the United States.

Associations Between Women's Economic and Social Empowerment and Intimate Partner Violence: Findings From a Microfinance Plus Program in Rural North West Province, South Africa

Given the mixed evidence on whether women's economic and social empowerment is beneficial or not for reducing intimate partner violence (IPV), we explored the relationship between women's empowerment and IPV risk. We analyzed data from baseline interviews with married women (n = 415) from the Intervention with Microfinance and Gender Equity (IMAGE) longitudinal study in rural South Africa. IMAGE combines a poverty-focused microfinance program with a gender-training curriculum. We fitted logistic regression models to explore associations between women's economic situation/empowerment and IPV. For the multivariable logistic regression, we fitted three models that progressively included variables to explore these associations further. Women who reported "few to many times" for not earning enough to cover their business costs faced higher odds of past year physical and/or sexual violence (adjusted odds ratio [aOR] = 6.1, 1.7-22.3, p = .01). Those who received a new loan experienced higher levels of past year emotional (aOR = 2.8, 1.1-7.4, p = .03) and economic abuse (aOR = 6.3, 2.2-18.5, p = .001). Women who reported that partners perceived their household contribution as not important faced higher odds of past year economic abuse (aOR = 2.8, 1.0-7.8, p = .05). Women who reported joint decision-making or partner making sole reproductive decisions reported higher levels of past year physical and/or sexual violence (aOR = 5.7, 0.9-39.4, p = .07) and emotional abuse (aOR = 3.0, 0.9-10.2, p = .08). Economic stress and aspects of women's empowerment, alongside established gender roles within marital relationships is associated with IPV risk in rural South Africa. Although improved economic conditions for women appears to be protective against physical and sexual IPV, associations between certain indicators of women's economic situation, empowerment, and IPV are inconsistent. We need to consider complementary programming and all types of IPV in research, intervention, and policy, as different aspects of empowerment have varying associations with different types of IPV (physical, sexual, emotional, and economic abuse).

Characteristics of women who use hormonal contraceptives and their population-level impacts on HIV infection in a cohort of South African women (2002-2016)

PURPOSE

Women's choice of contraceptive can have broader implications and may play a significant role in shaping their sexual practices. We aim to identify the characteristics of women who use hormonal injectables and those at high-risk of HIV infection. We also quantify the population-level impact of their shared characteristics on HIV incidence rates.

MATERIALS AND METHODS

Data from 9948 women who enrolled in six-HIV prevention trials conducted in South Africa (2002-2016) were included. We used logistic and Cox regression models and estimated the population-level impact of the use of injectables on HIV incidence in the multifactorial-model setting.

RESULTS

Using hormonal injectables were associated with increased risk of HIV infection (adjusted Hazard ratio (aHR):1.51, 95% CI:1.22, 1.86). At the population level less than 20% of the infections were associated with injectable contraceptives among younger women (i.e., less than 35 years of age). Factors including being single/not-cohabiting, using condoms at last sex, partner-related factors, and STI diagnosis were all identified as shared characteristics of women who preferred using hormonal injectables and those at high-risk of HIV infection. At the population level, these factors were associated with more than 50% of the infections among women younger than 35 years of age.

CONCLUSIONS

Our analysis presented evidence for the overlapping characteristics of the women who used hormonal injectables and those at high-risk of HIV infection. These findings reinforce the importance of comprehensive contraceptive counselling to women about the importance of dual protection, such as male condoms and hormonal contraceptives use.

Intersections of financial agency, gender dynamics, and HIV risk: A qualitative study with adolescent girls and young women in Zambia

Objectives: Recent research demonstrates that economic interventions may positively effect HIV risk among adolescent girls and young women (AGYW) in sub-Saharan Africa. Some evidence reveals potential associations between financial decision-making and bargaining power in sexual relationships. However, this evidence is mixed, nuanced, and limited. This paper explores how AGYW in Zambia understand financial agency and its effect on intimate relationships. Methods: In-depth qualitative interviews were conducted with 30 females aged 15-24 years residing in Kalingalinga, a low income, high-density residential area in Lusaka. Data were analysed using thematic content analysis. Results: Participants spoke of the ability to earn and spend money as reality for some and aspirational for many others, intrinsic to cultural and religious caveats influencing perceptions of agency for women. The transfer of financial independence to sexual agency within relationships was viewed as a mechanism for HIV risk reduction; however, male sexual privilege was an obstacle irrespective of financial decision-making. Conclusions: Programmes aiming to enhance financial agency for AGYW have the potential to reduce HIV sexual risk. Yet, to be most effective, integration with gender-transformative programmes is needed to address norms of male dominance that keep AGYW in positions of vulnerability.

The spectrum of sexual transaction: representations in young Africans' HIV-themed creative narratives

Sexual transaction, or any exchange of financial or material goods for sex, contributes to the disproportionate HIV burden among young women aged 15-24 years in sub-Saharan Africa. We analysed representations of sexual transactions in a sample of 363 narratives about HIV written by young Africans. The narratives were written at 4 time points (1997, 2005, 2008, 2014) by authors aged 10-24 years in urban and rural areas of Senegal, Burkina Faso, South-east Nigeria, Kenya and Eswatini, formerly Swaziland. We combined three analytical approaches: descriptive statistics of quantifiable characteristics of the narratives, thematic data analysis and a narrative-based approach. Representations reflect sexual transaction as a spectrum, with commercial sex work and sexual transactions that include romance at opposite ends. Narratives represent female characters increasingly motivated by a desire for social status symbols and by romantic love over time. Condemnation and stigmatisation of sexual transactions motivated by materialism remain similar across countries. In order to mitigate young women's disproportionate risk of HIV there is a need to combine efforts to address the economic marginalisation and gender inequality that drive sexual transactions with activities to promote skills and reflection and influence harmful norms, potentially drawing on companionate ideologies.
