Transactional sex and incident HIV infection in a cohort of young women from rural South Africa

Developmental Trajectories of Transactional Sex and Age-Disparate Relationships During Adolescence: An HPTN 068 Analysis

Transactional sex and sexual relationships with older partners increase HIV risk in adolescent girls and young women (AGYW), yet little is known about how these behaviors co-evolve over time. We characterize temporal patterns of transactional sex and age-disparate relationships among AGYW in South Africa. Longitudinal data are from a randomized controlled trial (HPTN 068) of school-aged, HIV-negative, AGYW who attended ≥ 3 study visits. We used group-based trajectory modeling to identify trajectories of transactional sex and age-disparate relationships (partner ≥ 5 years older) in the last year and assessed the interrelationship (conditional probability) between both trajectories. At baseline, median age was 14 years, 14.5% of girls were sexually active, and transactional sex (2.1%) and age-disparate relationships were uncommon (2.7%). We identified two trajectories for transactional sex ("low" [81.9%] and "increasing" [18.1%]) and two for age-disparate relationships ("low" [91.7%] and "increasing" [8.3%]). In a separate joint trajectory analysis, nearly a third (28%) had increasing trajectories for both transactional sex and age-disparate relationships, but most (53%) had a low trajectory of both outcomes. Baseline reporting of early sexual debut, depression, and inequitable gender norms were highest in the increasing transactional sex group. Prior pregnancy, early sexual debut, and IPV were highest among those with increasing age-disparate relationships. AGYW who engage in transactional sex or age-disparate partnerships in early adolescence are more likely to experience sustained engagement in both behaviors as they transition to adulthood, increasing HIV risk. Engaging girls early may maximize effectiveness of behavioral and biomedical HIV prevention efforts.

HIV incidence among women engaging in sex work in sub-Saharan Africa: a systematic review and meta-analysis

BACKGROUND

Women who engage in sex work in sub-Saharan Africa have a high risk of acquiring HIV infection. HIV incidence has declined among all women in sub-Saharan Africa, but trends among women who engage in sex work are poorly characterised. We synthesised data on HIV incidence among women who engage in sex work in sub-Saharan Africa and compared these with the total female population to understand relative incidence and trends over time.

METHODS

We searched MEDLINE, Embase, Global Health, and Google Scholar from Jan 1, 1990, to Feb 28, 2024, and grey literature for studies that reported empirical estimates of HIV incidence among women who engage in sex work in any sub-Saharan Africa country. We calculated incidence rate ratios (IRRs) compared with total female population incidence estimates matched for age, district, and year, did a meta-analysis of IRRs, and used a continuous mixed-effects model to estimate changes in IRR over time.

FINDINGS

From 32 studies done between 1985 and 2020, 2194 new HIV infections were observed among women who engage in sex work over 51 490 person-years. Median HIV incidence was 4·3 per 100 person years (IQR 2·8-7·0 per 100 person-years). Incidence among women who engage in sex work was eight times higher than matched total population women (IRR 7·8 [95% CI 5·1-11·8]), with larger relative difference in western and central Africa (19·9 [9·6-41·0]) than in eastern and southern Africa (4·9 [3·4-7·1]). There was no evidence that IRRs changed over time (IRR per 5 years: 0·9 [0·7-1·2]).

INTERPRETATION

Across sub-Saharan Africa, HIV incidence among women who engage in sex work remains disproportionately high compared with the total female population. However, constant relative incidence over time indicates HIV incidence among women who engage in sex work has declined at a similar rate. Location-specific data for women who engage in sex work incidence are sparse, but improved surveillance and standardisation of incidence measurement approaches could fill these gaps. Sustained and enhanced HIV prevention for women who engage in sex work is crucial to address continuing inequalities and ensure declines in new HIV infections.

Transactional sex and age-disparate sexual partnerships among adolescent girls and young women in Tanzania

Introduction

Adolescent girls and young women (AGYW) continue to experience a high incidence of HIV in southern and eastern Africa, even in the context of large-scale HIV prevention interventions. In Tanzania, AGYW account for the largest proportion of new infections and have a higher risk of HIV acquisition than males of comparable age.

Methods

We used routinely collected data from the PEPFAR/USAID-funded Sauti Project, a large combination HIV prevention program, to examine the relationship between transactional sex and sex with older partners among AGYW in Tanzania (2015-2020). Out-of-school AGYW 15-24 years completed a vulnerability index and were tested for HIV. We estimated weighted prevalence ratios (PR) and 95% confidence intervals (CI) for the associations of transactional sex (sex exchanged for money/services/gifts outside of sex work) and sex with older partners (≥5-years older, ≥10-years older) with prevalent HIV. Age cutoffs of 5 and 10 years were used to align partner age differences with age-disparate and intergenerational sex, respectively. We assessed potential synergism between exposures, and subgroup analyses explored associations among girls 15-19.

Results

Sixty seven thousand three hundred fifty seven AGYW completed the vulnerability index and 14,873 had captured HIV testing records. Median age was 20 years (IQR 18-22). Transactional sex and age-disparate sex were common (35% and 28%, respectively); 13% of AGYW reported both behaviors. HIV prevalence was associated with both transactional sex (PR: 1.28; 95% CI 1.00-1.63) and age-disparate sex (PR:1.26, 95% CI 0.99-1.60). In common referent analysis, transactional sex remained strongly associated with HIV, even in the absence of age-disparate sex (PR 1.41; 95% CI 1.02-1.94).

Discussion

Evidence of statistical synergism was not present, suggesting both transactional sex and age-disparate sex operate through similar pathways to increase HIV risk. Increased specificity within HIV prevention programs is needed to better meet the sexual and reproductive health needs of AGYW at high risk of HIV in Tanzania, including investment in tailored youth-friendly strategies for AGYW who have been marginalized from the current HIV response.

Correlates of Transactional Sex Among Black Men and Women Who Misuse Opioids

The rise in opioid misuse coincides with increased sexually transmitted infection (STI) and HIV incidence. Transactional sex is an under-researched phenomenon among Black Americans who misuse opioids, and may increase their risk of STI or HIV transmission. Given the disproportionate impact of the opioid epidemic on Black Americans and the risks associated with opioid misuse, the current study aims to investigate sociostructural factors, history of violence, and sexual risk factors associated with transactional sex among Black men and women. A sample of n = 375 Black adult Kentuckians reporting opioid misuse completed a survey including transactional sex, sociostructural, violence history, and sexual risk measures. Results of chi-squares and independent samples t-tests revealed that compared to men who did not report engaging in transactional sex, men who engaged in transactional sex were less educated, reported being sexually assaulted or having an unwanted sexual experience in their lifetime, and were more likely to use opioids or cocaine before or during sex in the last year. Women who engaged in transactional sex had a history of violence, more structural barriers, higher psychological distress, and engaged in more sexual risk behaviors compared to women who did not engage in transactional sex. Implications for future research and interventions with this population are discussed.

Differential Burden of HIV Among Adolescent Girls and Young Women by Places Associated With Sex Work: An Observational Study in Mombasa, Kenya

BACKGROUND

The design of HIV prevention programs for adolescent girls and young women (AGYW) are informed by data on who is at highest risk and where they can be reached. Places (hotspots) associated with selling sex are an established outreach strategy for sex work (SW) programs but could be used to reach other AGYW at high risk.

SETTING

This study took place in Mombasa, Kenya.

METHODS

We conducted a cross-sectional, bio-behavioural survey among (N = 1193) sexually active AGYW aged 14-24 years recruited at hotspots. We compared HIV prevalence by subgroup (SW; transactional sex, TS; and non-transactional sex), stratified by hotspot type (venues and nonvenues). We examined whether associations between HIV prevalence and hotspot/subgroup remained after adjustment for individual-level risk factors, and estimated HIV prevalence ratio with and without adjustment for these individual-level factors.

RESULTS

Overall HIV prevalence was 5.6%, 5.3% in venues and 7.3% in nonvenues. Overall SW HIV prevalence was 2-fold higher than among participants engaged in nontransactional sex. After adjusting for age and individual-level risk factors, HIV prevalence was 2.72 times higher among venue-based SWs (95% confidence interval: 1.56 to 4.85) and 2.11 times higher among nonvenue AGYW not engaged in SW (95% confidence interval: 0.97 to 4.30) compared with venue-based AGYW not engaged in SW.

CONCLUSION

AGYW who sell sex remain at high risk of HIV across types of hotspots. The residual pattern of elevated HIV burden by AGWY subgroup and hotspot type suggests that unmeasured, network-level factors underscore differential risks. As such, hotspots constitute a "place" to reach AGYW at high risk of HIV.

'You are looked upon as a luxury tool': Young Tanzanian women's perception of community norms supporting partner violence during transactional sex (kudanga)

This paper explores the definition of, and perceived community attitudes, toward kudanga, a Swahili street term for a type of transactional sex practised in Dar es Salaam, Tanzania. Rooted in economic and gender disparity, transactional sex increases adolescent girls' and young women's vulnerability to HIV and gender-based violence. We sought to understand perceived community attitudes about kudanga, and how the internalisation of norms surrounding gender-based violence relate to the experiences of young women who practise kudanga. Using qualitative data from focus group discussions with 37 young women, we found that community perceptions of kudanga were largely negative, and those who engaged in it were looked down upon and despised. Violence and lack of sexual agency were normalised when doing kudanga. However, young women understood kudanga to often be their best option to obtain economic stability and felt strongly that those who practised kudanga should not be stigmatised. Our research provides further evidence that transactional sex exists on a continuum and highlights the importance of reducing community stigma surrounding transactional sex as a means of decreasing risk of HIV and gender-based violence for young women. To our knowledge, this article is the first to explore kudanga.

Latent class analysis of barriers to HIV testing services and associations with sexual behaviour and HIV status among adolescents and young adults in Nigeria

INTRODUCTION

Adolescents and young adults (AYA) face multiple barriers to accessing healthcare services, which can interact, creating complex needs that often impact health behaviours, leading to increased vulnerability to HIV. We aimed to identify distinct AYA subgroups based on patterns of barriers to HIV testing services and assess the association between these barrier patterns and sexual behaviour, socio-demographics, and HIV status.

METHODS

Data were from Nigeria's AIDS Indicator and Impact Survey (NAIIS, 2018) and included 18,612 sexually active AYA aged 15-24 years who had never been tested for HIV and reported barriers to accessing HIV testing services. A Latent class analysis (LCA) model was built from 12 self-reported barrier types to identify distinct subgroups of AYA based on barrier patterns. Latent class regressions (LCR) were conducted to compare the socio-demographics, sexual behaviour, and HIV status across identified AYA subgroups. Sex behaviour characteristics include intergenerational sex, transactional sex, multiple sex partners, condom use, and knowledge of partner's HIV status.

RESULTS

Our LCA model identified four distinct AYA subgroups termed 'low-risk perception' (n = 7,361; 39.5%), 'consent and proximity' (n = 5,163; 27.74%), 'testing site' (n = 4,996; 26.84%), and 'cost and logistics' (n = 1,092; 5.87%). Compared to adolescents and young adults (AYA) in the low-risk perception class, those in the consent and proximity class were more likely to report engaging in intergenerational sex (aOR 1.17, 95% CI 1.02-1.35), transactional sex (aOR 1.50, 95% CI 1.23-1.84), and have multiple sex partners (aOR 1.75, 95% CI 1.39-2.20), while being less likely to report condom use (aOR 0.79, 95% CI 0.63-0.99). AYA in the testing site class were more likely to report intergenerational sex (aOR 1.21, 95% CI 1.04-1.39) and transactional sex (aOR 1.53, 95% CI 1.26-1.85). AYA in the cost and logistics class were more likely to engage in transactional sex (aOR 2.12, 95% CI 1.58-2.84) and less likely to report condom use (aOR 0.58, 95% CI 0.34-0.98). There was no significant relationship between barrier subgroup membership and HIV status. However, being female, aged 15-24 years, married or cohabiting, residing in the Southsouth zone, and of Christian religion increased the likelihood of being HIV infected.

CONCLUSIONS

Patterns of barriers to HIV testing are linked with differences in sexual behaviour and sociodemographic profiles among AYA, with the latter driving differences in HIV status. Findings can improve combination healthcare packages aimed at simultaneously addressing multiple barriers and determinants of vulnerability to HIV among AYA.

Acceptability of the dapivirine vaginal ring for HIV-1 prevention among women reporting engagement in transactional sex

We assessed if acceptability of the dapivirine vaginal ring for HIV prevention differed among the subgroup of women who reported engaging in transactional sex prior to enrollment in MTN-020/ASPIRE (phase III trial in Malawi, South Africa, Uganda, and Zimbabwe, 2012-2015; n = 2629). Transactional sex was defined as receipt of money, goods, gifts, drugs, or shelter in exchange for sex in the past year. Dimensions of acceptability included: ease of use and physical sensation in situ, impacts on sex, partner's opinion, and likelihood of future use. We used Poisson regression models with robust standard errors to compare risk of acceptability challenges by baseline history of transactional sex. At product discontinuation, women exchanging sex found the ring comfortable (90%), easy to insert (92%) and nearly all (96%) were likely to use the ring in the future. Women who had exchanged sex were more likely to report feeling the ring during sex (ARR 1.43, 95% CI: 1.09, 1.89; p = 0.01) and slightly more likely to mind wearing the ring during menses (ARR 1.22, 95% CI: 1.01, 1,46; p = 0.04) and during sex (ARR 1.22, 95% CI: 1.02, 1.45; p = 0.03). Messaging and counseling should include enhanced support for use during sex and menses to support optimal use.

Prevalence and determinants of condom use among the youth in Malawi: evidence from the 2015/16 Malawi Demographic and Health Survey

BACKGROUND

Unprotected sexual intercourse among the youth is common in Malawi. This has led to high rates of sexually transmitted infections (STIs), Human Immunodeficiency Virus (HIV), and unplanned pregnancies. The study investigated the prevalence and the determinants of male and female condom use for the prevention of sexually transmitted infections and unplanned pregnancies among the youth in Malawi.

METHODS

The 2015/2016 Malawi Demographic and Health Survey (MDHS) data were used among 15 to 24-year-old male and female who had sexual intercourse four months preceding the survey. A total of 1543 male and 5143 female were selected from 3226 male and 10,367 female respectively and analyzed with SPSS version 20 using.descriptive, bivariate, and logistic regression.

RESULTS

The study found a low prevalence (27.1%) of condom use among the youth in the last sexual intercourse within four months before the survey. More male (55.8%) used condoms than female (18.5%). The significant predictors of condom use among the male and female youth were: being sexually active (OR 0.39 CI 0.33-0.47), aged 20-24 (OR 0.80 CI 0.68-0.95), ever married (OR 0.07 CI 0.06-0.08), coming from central region (OR 0.56 CI 0.40-0.77), and southern region (OR 0.59 CI 0.42-0.83), residing in the rural area (OR 0.74 CI 0.61-0.90) and ever tested of HIV (OR 1.29 CI 1.03-1.55).

CONCLUSION

Having established low prevalence of condom use among the youth in Malawi, there is a need to scale up programs and policies that target the youth to practice safe sex, which will assist in addressing the challenges of STIs, including HIV, and preventing unplanned pregnancies in Malawi.

HIV incidence among women engaging in sex work in sub-Saharan Africa: a systematic review and meta-analysis

Introduction

HIV incidence among women in sub-Saharan Africa (SSA) has declined steadily, but it is unknown whether new infections among women who engage in sex work (WESW) have declined at a similar rate. We synthesised estimates of HIV incidence among WESW in SSA and compared these to the wider female population to understand levels and trends in incidence over time.

Methods

We searched Medline, Embase, Global Health, Popline, Web of Science, and Google Scholar from January 1990 to October 2022, and grey literature for estimates of HIV incidence among WESW in SSA. We included studies reporting empirical estimates in any SSA country. We calculated incidence rate ratios (IRR) compared to age-district-year matched total female population incidence estimates. We conducted a meta-analysis of IRRs and used a continuous mixed-effects model to estimate changes in IRR over time.

Results

From 32 studies between 1985 and 2020, 2,194 new HIV infections were observed in WESW over 51,000 person-years (py). Median HIV incidence was 4.3/100py (IQR 2.8-7.0/100py), declining from a median of 5.96/100py between 1985 and 1995 to a median of 3.2/100py between 2010 and 2020. Incidence among WESW was nine times higher than in matched total population women (RR 8.6, 95%CI: 5.7-12.9), and greater in Western and Central Africa (RR 22.4, 95%CI: 11.3-44.3) than in Eastern and Southern Africa (RR 5.3, 95%CI: 3.7-7.6). Annual changes in log IRRs were minimal (-0.1% 95%CI: -6.9 to +6.8%).

Conclusions

Across SSA, HIV incidence among WESW remains disproportionately high compared to the total female population but showed similar rates of decline between 1990 and 2020. Improved surveillance and standardisation of approaches to obtain empirical estimates of sex worker incidence would enable a clearer understanding of whether we are on track to meet global targets for this population and better support data-driven HIV prevention programming.

Strong Father-Child Relationships and Other Positive Childhood Experiences, Adverse Childhood Experiences, and Sexual Risk Factors for HIV among Young Adults Aged 19-24 Years, Namibia, 2019: A Cross-Sectional Study

Using cross-sectional data from the 2019 Namibia Violence Against Children and Youth Survey and sex-stratified multivariable models, we assessed the associations between four different positive childhood experiences (PCEs) and having ≥3 adverse childhood experiences (ACEs), including ≥3 ACE-PCE interaction terms, and seven sexual risk factors for HIV acquisition among young adults aged 19-24 years. One PCE, having a strong father-child relationship, was inversely associated with two risk factors among women (lifetime transactional sex (OR, 0.4; 95% CI, 0.2-0.7) and recent age-disparate sexual relationships (OR, 0.3; 95% CI, 0.2-0.5)), and significantly interacted with having ≥3 ACEs for three risk factors among women (not knowing a partner's HIV status, infrequently using condoms, and ever having an STI) and one among men (having multiple sexual partners in the past year). The other PCEs were significantly associated with ≤1 HIV risk factor and had no significant interaction terms. Strong father-child relationships may reduce HIV acquisition risk and mitigate the effect of childhood adversity on HIV risk among young adults in Namibia.

Experiences of Exploitation and Associations With Economic Abuse in Adolescent Dating Relationships: Findings From a U.S. Cross-Sectional Survey

Adolescent relationship abuse (ARA) (i.e. physical, sexual, psychological, or economic abuse in the context of romantic relationships) is associated with adverse health outcomes, including anxiety, depression, suicidality, unintended pregnancy, and substance misuse. A related phenomenon, reproductive coercion involves interference with the reproductive decision making of a partner with the intention of promoting pregnancy or controlling outcomes of a pregnancy. Reproductive coercion is associated with unintended pregnancy, partner violence, and sexually transmitted infections. Little is known about the intersection between economic ARA, sexual exploitation, and reproductive coercion. This paper explores the intersections between reproductive coercion, transactional sex, and economic abuse victimization in adolescent dating relationships. In an online survey, 1,752 adolescents (ages 13-17) were asked about economic adolescent relationship abuse (educational, employment and financial interference), transactional sex, reproductive coercion, and contraceptive access within their relationships. We assessed associations with chi-square tests and logistic regression analysis. Youth who experienced economic ARA (70%, 1,232) reported financial dependence on their partner, contraceptive access, and reproductive coercion (74-83%; p-values<0.001) more often than their counterparts without economic ARA. Adolescents experiencing economic abuse were more likely to report transactional sex (aOR = 2.76, CI [2.12, 3.60], p < .001), depending on a partner to pay for contraception or birth control (aOR = 2.20, CI [1.71, 2.84], p < .001), and reproductive coercion (aOR = 3.20, CI [2.37, 4.32], p < .001). Youth-serving providers and agencies should be aware of intersections between economic ARA, transactional sex, financial dependence, and reproductive coercion, particularly for adolescents with health-related social needs.

HIV Related Behaviors Among Male Partners of Adolescent Girls and Young Women in Rural South Africa

Improving men's engagement in HIV prevention is not only essential for reducing their own HIV risk but also the risk of transmitting HIV to their female partners. We conducted a cross-sectional survey using a population-based sample of men (age 18-30) who reported being a partner of an adolescent girls and young women (AGYW) in South Africa (N = 2827). We used logit-binomial regression models to examine associations among men's partnership characteristics, HIV risk perceptions, and HIV-related behaviors and examine differences by male partner age (younger men (18-24) vs. older men (25-30)) and age difference between partners (age-concordant (< 5 years) vs. age-disparate (≥ 5 years)). Most men reported inconsistent condom use (85%) and nearly half reported engaging in transactional sex (48%). Older men were just as likely as younger men, and men with age-disparate and age-concordant partners, to inconsistently use condoms, engage in transactional sex, and perpetrate intimate partner violence. Most men also reported a very high interest in pre-exposure prophylaxis (PrEP) (77%) and half reported having an HIV test in the past year (50%). There were no differences by male partner age or age difference between partners in PrEP interest but older men and men in age-discordant relationships were more likely than younger men and men in age-concordant relationships to have an HIV test in the past year. Male partners of AGYW in South Africa are engaging in HIV-related behaviors and need HIV prevention interventions to reduce risk for themselves and their female partners.

Longitudinal patterns of initiation, persistence, and cycling on preexposure prophylaxis among female sex workers and adolescent girls and young women in South Africa

OBJECTIVE

Female sex workers (FSW) and adolescent girls and young women (AGYW) face a disproportionately high risk of HIV in South Africa. Oral preexposure prophylaxis (PrEP) can avert new infections, but its effectiveness is linked to consistent use. Early discontinuation of PrEP in this population is high, but less is known about longitudinal patterns of PrEP use, including patterns of re-initiation and cycling.

DESIGN

Longitudinal descriptive analysis of routine program data.

METHODS

Between 2016 and 2021, 40 681 FSW and AGYW initiated PrEP at TB HIV Care, the largest PrEP provider to this population in South Africa and were included. Using survival analyses and group-based trajectory modeling, we described patterns of initiation, discontinuation, re-initiation, and cycling.

RESULTS

Total initiations increased over the life of the program for both FSW and AGYW. About 40% of FSW [0.41, 95% confidence interval (CI) [0.40-0.42]] and AGYW (0.38, 95% CI [0.37-0.38]) remained on PrEP at one month. FSW were more likely to restart PrEP, however <10% restarted PrEP within a year of initiation. Three latent trajectory groups of PrEP use were identified for FSW (low use, early cycling, and ongoing cycling) and two for AGYW (low use and ongoing cycling). Persistence was negatively associated with initiation among AGYW, but there was no clear relationship among FSW. Those initiating later in the program and older women had a reduced risk of discontinuation.

CONCLUSIONS

Persistence on PrEP was low, but cycling on and off PrEP was common, with early missed visits and inconsistent, but ongoing use. A push to increase PrEP initiations needs to factor in readiness and persistence support, to achieve public health impact.

High prevalence of risky sexual behaviour among key populations receiving antiretroviral therapy at a large HIV clinic in northern Uganda

Background

Risky sexual behaviour (RSB) among key populations pose a significant risk of human immunodeficiency virus (HIV) infection but remains understudied.

Objectives

We assessed the prevalence and factors associated with RSB among key populations living with HIV (KPLHIV) in the post-conflict region of northern Uganda.

Methods

We designed a cross-sectional study using secondary data, with the outcome as RSB defined as having multiple sexual partners, or condomless sex in the past 3 months, or sexual intercourse with a commercial sex worker in the past 3 months, or sexual intercourse under the influence of substance use in the past 3 months. We used modified Poisson regression to determine factors associated with RSB, reported as adjusted risk ratio (aRR) with 95% confidence interval (CI).

Results

We studied 165 participants and 122 (73.9%) reported RSB and this was more likely among heterosexual females (aRR, 2.39; 95% CI, 1.54-3.71), the married (aRR, 1.92; 95% CI, 1.42-2.49) or separated participants (aRR, 1.47; 95% CI, 1.21-1.79), and transgender persons (aRR, 3.71; 95% CI, 2.05-6.71).

Conclusions

RSB is highly prevalent among KPLHIV in northern Uganda so they should be targeted with HIV prevention and behavioural interventions to prevent potential HIV transmission to the general population.

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.

Association between lifetime sexual violence victimization and selected health conditions and risk behaviors among 13-24-year-olds in Lesotho: Results from the Violence Against Children and Youth Survey (VACS), 2018

BACKGROUND

Sexual violence is a serious public health concern worldwide. In Lesotho, one in seven women and one in twenty men aged 18 years and older experienced sexual violence during childhood. Sexual violence victimization may lead to long-term mental and physical health issues among victims, regardless of gender.

OBJECTIVE

To estimate the prevalence of lifetime sexual violence victimization (SV) among 13-24-year-olds in Lesotho and assess its association with selected health conditions and risk behaviors.

PARTICIPANTS AND SETTING

Data from 13 to 24-year-old participants (n = 8568) of the 2018 Lesotho Violence Against Children and Youth Survey were analyzed.

METHODS

SV was defined as reporting one or more types of sexual violence at any age. Logistic regression analyses measured associations between SV and selected health conditions (suicidal thoughts, self-harm behaviors, mental distress, STIs, and HIV), and risk behaviors (binge drinking in the past 30 days, drug use in the past 30 days, infrequent condom use in the past 12 months, multiple sex partners in the past 12 months, and transactional sex in the past 12 months).

RESULTS

After controlling for study covariates, SV was significantly associated with self-harm behaviors, suicidal thoughts, ever having an STI, binge drinking in the past 30 days, infrequent condom use in the past 12 months, and multiple sex partners in the past 12 months for both males and females; and mental distress and transactional sex in the past 12 months for females.

CONCLUSIONS

Preventing SV against children and youth in Lesotho may improve their health and wellbeing.

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.

Global, regional, and national burdens of HIV and other sexually transmitted infections in adolescents and young adults aged 10-24 years from 1990 to 2019: a trend analysis based on the Global Burden of Disease Study 2019

BACKGROUND

Sexually transmitted infections (STIs), including HIV, are major sexual health issues among adolescents and young adults globally, but data on the burden and trends of these diseases are sparse. We aimed to assess the trends in the burden of HIV and other STIs among adolescents and young adults aged 10-24 years from 1990 to 2019 on the global, regional, and national level.

METHODS

In this trend analysis based on the Global Burden of Diseases, Injuries, and Risk Factors Study (GBD) 2019, we reported on the number, rates per 100 000 population, and average annual percentage changes (AAPCs) of incidence and disability-adjusted life-years (DALYs) of HIV and other STIs (syphilis, chlamydia, gonorrhoea, trichomonas, and genital herpes) at the global, regional, and national level among individuals aged 10-24 years. We further analysed these global trends by age, sex, and social development index (SDI). We also used joinpoint regression analysis to identify the year with the most substantial changes in global trends.

FINDINGS

Globally, the incidence of HIV among adolescents and young adults decreased from 34·5 per 100 000 population (95% uncertainty interval [UI] 29·3 to 39·7) in 1990 to 22·7 per 100 000 population (20·3 to 25·8) in 2019, AAPC -2·6 [95% CI -3·1 to -2·0]); specific years in which HIV incidence decreased significantly were 1998, 2005, and 2014. Incidence of other STIs increased from 6986·3 per 100 000 population (95% UI 5504·8-8645·0) in 1990 to 7088·7 100 000 population (5620·1-8697) in 2019 (AAPC 0·2 [95% CI 0·1-0·3]); we found a substantial decrease in the incidence of other STIs in 2011 only. The rate of decrease in the incidence of other global STIs between 2009 and 2019 was approximately one-fifth the rate of the decrease in the global incidence of HIV for the same time period (AAPC -0·7 [95% CI -0·8 to -0·7] vs AAPC -3·4 [-3·8 to -3·1]). Regionally, sub-Saharan Africa had the highest incidence and highest DALYs from HIV and other STIs, and Oceania and Eastern Europe had the largest increase in the incidence and DALYs from HIV and other STIs between 1990 and 2019. By SDI quintile, the middle-SDI countries had the largest increase in HIV incidence between 1990 and 2019 and the DALYs from other STIs in the same period decreased in all SDI quintiles. Globally, females accounted for 278 076 (65·8%) of the 0·42 million incident HIV cases in 2019 and 68 115 077 (51·6%) of the 132·0 million incident cases of other STIs. Of all age groups, adolescents aged 10-14 years had the largest increase in the incidence of other STIs between 1990 and 2019 (from 1158·9 per 100 000 population [95% UI 857·8-1556·5] in 1990 to 1215·4 per 100 000 population [893·5-1616·1] in 2019; AAPC 0·1 [95% CI 0·1-0·2]). The individual STIs with the highest incident rates varied between age groups and sex.

INTERPRETATION

Global HIV incidence among adolescents and young adults decreased between 1990 and 2019, with significant decreases coinciding with the implementation of antiretroviral therapy and pre-exposure prophylaxis. The incidence of other STIs in this population increased over the same period and only started decreasing in 2011, at a rate of only one-fifth of the rate of decrease of HIV. Earlier sexual health education and targeted STI screening are urgently required for adolescents and young adults.

Differentiating the incidence and burden of HIV by age among women who sell sex: a systematic review and meta-analysis

INTRODUCTION

Young women who sell sex (YWSS) are at heightened risk of HIV acquisition and transmission and are among the least engaged in HIV services. There is insufficient epidemiologic evidence characterizing the burden of HIV among YWSS, particularly as compared to older WSS. These data are needed to design and tailor effective HIV prevention and treatment programmes for this population.

METHODS

We conducted two parallel systematic reviews and meta-analyses to define both the immediate and long-term HIV risks for YWSS, including among women engaged in sex work, survival sex and transactional sex. In the first review, we identified and synthesized published studies of HIV incidence comparing estimates for cisgender women ≤24 years of age versus >24. In the second review, we identified and synthesized studies of HIV prevalence, comparing estimates for cisgender women who initiated selling sex <18 versus ≥18 years. In both reviews, we completed a search of four databases for articles in any language and any geographic area published from 1 January 1980 until 12 February 2021. Included articles were assessed for quality and a random effects model was used to calculate pooled effect estimates for each review.

RESULTS AND DISCUSSION

We identified 12 studies for the HIV incidence review and 18 studies for the HIV prevalence review. In a meta-analysis, HIV incidence was elevated in younger (5.3 per 100 person-years [PY]; 95% confidence interval [CI]: 3.5, 7.1) compared to older women (2.8 per 100 PY; 95% CI: 1.7, 3.9), although CIs overlapped. HIV prevalence among those who initiated selling sex <18 years of age (28.8; 95% CI: 18.9, 38.7) was higher than those who initiated later (20.5; 95% CI: 12.4, 28.6).

CONCLUSIONS

These companion reviews offer an important perspective on the relative HIV risk of engaging in selling sex at a younger age. Our findings highlight the unique and intersectional challenges YWSS face, and the importance of ensuring that health services are tailored to meet their specific needs. Research and programming should routinely stratify data into meaningful age bands to differentiate and intervene within this population.

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.

Substantial Increase in Transactional Sex and HIV Risk Among Adolescents During the COVID-19 Pandemic: Results From a Repeated Cross-Sectional Study in Botswana

The COVID-19 pandemic and resulting public health response has disrupted the lives of adolescents and their families worldwide. We evaluated the impact of the pandemic on attitudes, beliefs, and sexual risk behavior among adolescents in Botswana. Participants were recruited using household-based sampling across residential districts (blocks) in and around Gaborone, Botswana, and completed surveys on laptop computers at a private, central location. We compared baseline survey data from 380 adolescents who completed the survey pre-pandemic (n = 139) to those who completed the survey intra-pandemic (n = 241). Participants had a mean age of 15.2 years; 58.6% were girls and 41.4% were boys. Intra-pandemic, participants reported greater engagement in transactional sex (38.1% compared to 13.6% pre-pandemic, p <. 05), more favorable attitudes toward transactional sex with sugar daddies and sugar mommies (p <. 05), greater intentions to remain sexually active in the future (29.2% vs.13.6%, respectively, p <.05), and lower self-efficacy in handling risky sexual situations (p < .01). Public health interventions that lessen these concerning shifts in attitudes and behaviors will be key to protecting the sexual health of adolescents and to supporting their safe transition to adulthood.

"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.

Differences in Sexual Behavior and Partner Notification for Sexually Transmitted Infections Between the Out of School Youth and University Students in a Peri-Urban District in South Africa-A Cross-Sectional Survey

The increase in sexually transmitted infections (STIs) in young people is a public health concern. Among those in university and out of school, different contextual factors contribute to their risky sexual behavior and increased susceptibility to STIs and HIV. There are limited comparative studies examining risky sexual behavior and partner notification (PN) between these two groups, particularly in South Africa. We investigated sexual behaviors, self-reported STI diagnosis, health seeking behavior, and preferred PN methods of university students and out of school youth. A descriptive cross-sectional survey was used using convenient sampling to select 917 students across five health sciences universities and through periodic sampling 699 out of school youth were selected from two main local shopping centers in South Africa. Descriptive statistics, bivariate and multivariable logistic analysis were performed using Stata IC version 14. More university students (71.7%) than out of school youth were in casual relationships (28.3%), with half of out of school youth being in steady relations (50.2%). Moreover, university students (65.7%) used a condom in the past 6 months compared to their counterparts (34.3%). Of the 124 youth who were diagnosed with STI in the past 12 months, majority (n = 106, 85%) were out of school youth. The probability of notifying a partner about a STI infection was 82% among university students compared to their counterparts (p = >0.05). The odds of notifying a partner was 1.79 times more for those having multiple sexual partners than those who had only one partner. Both groups preferred a face-to-face STI disclosure with partner; however, more university students (67%) preferred SMS notification than PN referral slips as compared to out of school youth (42%). Both the university students and the out of school youth engaged in risky sexual behaviors. Both groups preferred face-to-face and clinic SMS partner notifications, even though university students were in the majority. There is a need for developing health promotion scripts on disclosing STIs to sexual partners to empower the majority of the youth who prefer face-to-face PN over the prescribed methods.

Adolescent Mothers in Eastern and Southern Africa: An Overlooked and Uniquely Vulnerable Subpopulation in the Fight Against HIV

PURPOSE

Adolescent girls (10-19 years) in Eastern and Southern Africa face a high risk of pregnancy and HIV infection. However, few studies have examined whether the profound developmental, social, and economic changes that accompany adolescent motherhood contribute to HIV risk. This study examines the intersection between adolescent motherhood and HIV infection across 10 Eastern and Southern African countries, where over half of all HIV infections occur among adolescent girls.

METHODS

To evaluate whether adolescent motherhood is associated with HIV infection, we used Demographic and Health Survey data on girls (15-19 years) with HIV test results (N = 19,932) from Eswatini, Kenya, Lesotho, Malawi, Mozambique, South Africa, Tanzania, Uganda, Zambia, and Zimbabwe. We examined unweighted bivariate and multivariable associations between adolescent motherhood and HIV using mixed effects logistic regression models that included a country-level random intercept. We examined heterogeneity in the association by testing country-level random slopes using a likelihood ratio test and used intraclass correlation to measure the proportion of total variance explained at the country level.

RESULTS

Nearly one fifth of adolescent girls were mothers (range: 9.80%-38.90%), and the HIV prevalence among all adolescent girls was 3.3% (range: 1.03%-10.07%). Relative to nonmothers, adolescent mothers were, on average, older, poorer, and more likely to be married, rural dwellers, and household heads. Adolescent motherhood was positively associated with HIV infection in bivariate and multivariable analyses (odds ratio: 1.87; 95% confidence interval: 1.57-2.23; adjusted odds ratio: 1.53; 95% CI: 1.24-1.89).

DISCUSSION

Among adolescents with HIV test results, we observed a robust association between adolescent motherhood and HIV infection across 10 high-burden countries.

Determining HIV risk for Adolescent Girls and Young Women (AGYW) in relationships with "Blessers" and age-disparate partners: a cross-sectional survey in four districts in South Africa

BACKGROUND

HIV incidence among adolescent girls and young women (AGYW) remains high, with their male partners a prominent factor in sustaining these elevated rates. Partnership characteristics remain important metrics for determining HIV risk, with evidence indicating that AGYW engaged in transactional and age-disparate relationships face greater HIV exposure. This study examines the risk posed to AGYW in a relationship with a "Blesser", defined as male who provides his female partner with their material needs or desires in exchange for a sexual relationship, an age-disparate (5 or more years older) partner, and the potential compounded risk of being a relationship with a partner or partners who are considered both a "Blesser" and age-disparate.

METHODS

A cross -sectional household based representative sample of AGYW (aged between 12-24 years) were enrolled in the study (n = 18 926) from the districts of City of Johannesburg and Ekurhuleni in the Gauteng province and the Districts of eThekwini and uMgungundlovu in the province of KwaZulu-Natal (KZN) in South Africa between March 13, 2017 to June 22, 2018. Participants completed a structured questionnaire and provided finger-prick blood samples for laboratory measurements. Our analysis used descriptive statistics and multiple binary logistic regressions accounting for survey weights, clustering and stratification.

FINDINGS

The median age of the sample was 21 years old (Interquartile range: 19-23) and nearly three quarters (73.7%) were currently attending school. Whilst all relationships exposed AGYW to potential HIV risk, multiple binary logistic regression analysis revealed that AGYW in a relationship with both a Blesser and an age-disparate partner were more likely to be HIV positive (AOR: 3.12, 95% CI: 1.76-5.53, p < 0.001), diagnosed with an STI (AOR: 4.60, 95% CI: 2.99-7.08, p < 0.001), had 2 or more sexual partners in the previous 12 months (AOR: 6.37, 95% CI: 3.85-10.54, p < 0.001), engaged in sexual activity at age 15 or younger (AOR: 3.67, 95% CI: 2.36-5.69, p < 0.001) and more likely to have ever been pregnant (AOR: 2.60, 95% CI: 1.24-5.45, p < 0.05) than those not in a relationship with either a Blesser or age-disparate partner.

CONCLUSION

Different relationships present different HIV risk to AGYW. AGYW who had engaged in relationships with both a Blesser and an age-disparate partner were at greater HIV risk when examined against these relationships independent of one another. The data reveals the compounded HIV risk of being in both a transactional and age-disparate relationship.

Intimate Partner Violence (IPV) and Associated Factors in HPTN 071 (PopART) Study Communities in Zambia and South Africa-A Comparison by HIV Status

The HPTN 071(PopART) study was a community-randomised trial in Zambia and South Africa, examining the impact of combination-prevention including universal testing and treatment (UTT), on HIV-incidence. This sub-study evaluated factors associated with IPV (physical and/or sexual) to identify differences by HIV status. During 2015-16, a random subset of adults who participated in the first year of the PopART intervention were recruited and standardised questionnaires were administered. Logistic regression was performed to estimate odds ratios of factors associated with IPV. Among > 700 women studied (300 HIV-negative;400 HIV-positive), ~ 20% reported experiencing physical and/or sexual violence in the last 12-months. Sexual violence was similar by HIV status, but physical violence and reporting both physical/sexual violence was more common among HIV-positive women. Spending nights away from the community in the last 12-months was associated with higher odds of IPV among both HIV-negative (aOR 3.17, 95% CI 1.02-9.81) and HIV-positive women (aOR 1.79, 95% CI 0.99-3.24). Among HIV-positive women, financial autonomy was associated with reduced IPV (aOR:0.41,95%CI:0.23-0.75) while pregnancy in the last 12-months (aOR 2.25, 95% CI 1.07-4.74), risk of alcohol dependence (aOR 2.75, 95% CI 1.51-5.00) and risk of mental distress (aOR 2.62, 95% CI 1.33-5.16) were associated with increased IPV. Among HIV-negative women reporting sex in the last 12-months, transactional sex (aOR 3.97, 95% CI 1.02-15.37) and not knowing partner's HIV status (aOR 3.01, 95% CI 1.24-7.29) were associated with IPV. IPV was commonly reported in the study population and factors associated with IPV differed by HIV status. The association of mobility with IPV warrants further research. The high prevalence of harmful alcohol use and mental distress, and their association with IPV among HIV-positive women require urgent attention.

The Burden of HIV Infection among Pregnant Women Attending Antenatal Care in Jimma University Specialized Hospital in Ethiopia: A Retrospective Observational Study

Background

The HIV (human immunodeficiency virus) epidemic enters its fifth decade amid a global pandemic. Nearly 61% of the people newly infected with HIV live in sub-Saharan Africa (SSA). The virus is transmitted from mother to child during pregnancy, labour, delivery, and breastfeeding, warranting routine counselling at antenatal care (ANC). Hence, this study aimed to determine the prevalence and trend of HIV infection among pregnant women on ANC follow-up at Jimma University Specialized Hospital (JUSH) in Ethiopia from November 2018 to 2021.

Methods

A retrospective cross-sectional study was conducted from June 25, 2021, to November 30, 2021. A total of 634 mothers were sampled by systematic random sampling, and the data were analyzed by descriptive statistics package of SPSS software. A chi-square test was employed to assess an association between variables. Analyses outputs were summarized and presented in tables and figures.

Results

Among the sampled women (634), 96.1% received counselling services on the prevention of maternal-to-child transmission of HIV/AIDS. Around 83.1% of the mothers refused to consult their partners and were unable to persuade their surrogate or afraid to discuss HIV serostatus tests. The overall prevalence of HIV infection among pregnant mothers was 7.1% and no significant decrease in the trends of HIV prevalence over the three years study period (p value >0.05). The seroprevalence is high in urban residents (4.4%) and age group of 25–29 years (38.9%) (p value <0.05). Residence, level of education attained, and marital status of women were significantly associated (p value <0.05) with seropositivity.

Conclusion

HIV burden among ANC attendees in JUSH is high as compared to the national figure and its trend over three years is steady. Accordingly, mandatory early screening tests and community-based education are mandatory for all women and adolescent girls in the reproductive age group.

HIV and Herpes Simplex Virus Type 2 Incidence Among Adolescent Mothers in South Africa: A Longitudinal Analysis of HIV Prevention Trials Network 068 Data

BACKGROUND

Adolescent motherhood is common in South Africa and occurs against a backdrop of high HIV risk. While childbearing during adolescence may result in social and economic strain that may negatively impact health, there has been limited study of whether adolescent motherhood increases the risk of HIV or herpes simplex virus type 2 (HSV-2) acquisition or engagement in high-risk sexual partnerships.

SETTING

Data are from HIV Prevention Trials Network 068, a longitudinal conditional cash transfer study of adolescent girls and young women (age, 13-23) in rural South Africa.

METHODS

We used survival analysis to estimate hazard ratios to determine if adolescent motherhood (live birth before 20 years) predicted incident HIV and incident HSV-2 and generalized estimating equations for behavioral risk ratios to determine if adolescent motherhood was associated with transactional sex and age-disparate partnerships.

RESULTS

Of 2452 adolescent girls and young women who were HIV negative at baseline, 5% were adolescent mothers; 16% were adolescent mothers by the end of the study period. After controlling for covariates, adolescent motherhood predicted incident HSV-2 acquisition [ adjusted hazard ratios, 1.30; 95% confidence interval (CI): 1.01 to 1.95] but not HIV acquisition ( adjusted hazard ratios, 1.19; 95% CI, 0.76 to 1.86). Adolescent motherhood was also associated with being in an age-disparate partnership (adjusted risk ratio, 1.30; 95% CI: 1.07 to 1.58) but not transactional sex.

CONCLUSION

Adolescent motherhood increased the risk of HSV-2 and engagement in age-disparate partnerships, both known risk factors for HIV infection. Sexually transmitted infection screening and/or tailored combination HIV prevention interventions that account for the context of adolescent motherhood are critical to maximize adolescent mothers' long-term health and to meet UNAIDS 95-95-95 targets by 2030.

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.

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.

Cash transfers for HIV prevention: A systematic review

BACKGROUND

Given the success of cash programs in improving health outcomes and addressing upstream drivers of HIV risk such as poverty and education, there has been an increasing interest in their potential to improve HIV prevention and care outcomes. Recent reviews have documented the impacts of structural interventions on HIV prevention, but evidence about the effects of cash transfer programs on HIV prevention has not been systematically reviewed for several years.

METHODS AND FINDINGS

We did a systematic review of published and unpublished literature to update and summarize the evidence around cash programs for HIV prevention from January 2000 to December 17, 2020. We included studies with either a cash transfer intervention, savings program, or program to reduce school costs. Included studies measured the program's impact on HIV infection, other sexually transmitted infections (STIs), or sexual behaviors. We screened 1,565 studies and examined 78 in full-text review to identify a total of 45 peer-reviewed publications and reports from 27 different interventions or populations. We did not do a meta-analysis given the range of outcomes and types of cash transfer interventions assessed. Most studies were conducted in sub-Saharan Africa (N = 23; South Africa, Tanzania, Malawi, Lesotho, Kenya, Uganda, Zimbabwe, Zambia, and eSwatini) followed by Mexico (N = 2), the United States (N = 1), and Mongolia (N = 1)). Of the 27 studies, 20 (72%) were randomized trials, 5 (20%) were observational studies, 1 (4%) was a case-control study, and 1 (4%) was quasi-experimental. Most studies did not identify a strong association between the program and sexual behaviors, except sexual debut (10/18 finding an association; 56%). Eight of the 27 studies included HIV biomarkers, but only 3 found a large reduction in HIV incidence or prevalence, and the rest found no statistically significant association. Of the studies that identified a statistically significant association with other STIs (N = 4/8), 2 involved incentives for staying free of the STI, and the other 2 were cash transfer programs for adolescent girls that had conditionalities related to secondary schooling. Study limitations include the small number of studies in key populations and examining interventions to reduce school costs and matched saving programs.

CONCLUSIONS

The evidence base for large-scale impacts of cash transfers reducing HIV risk is limited; however, government social protection cash transfer programs and programs that incentivize school attendance among adolescent girls and young women show the greatest promise for HIV prevention.

Modeling Combination Interventions to Prevent Human Immunodeficiency Virus in Adolescent Girls and Young Women in South Africa (HIV Prevention Trials Network 068)

BACKGROUND

Combination interventions may be an effective way to prevent human immunodeficiency virus (HIV) in adolescent girls and young women. However, current studies are not designed to understand which specific interventions and combinations will be most effective. We estimate the possible impacts of interventions on a combination of factors associated with HIV.

METHODS

We used the g-formula to model interventions on combinations of HIV risk factors to identify those that would prevent the most incident HIV infections, including low school attendance, intimate partner violence, depression, transactional sex, and age-disparate partnerships. We used data from the HIV Prevention Trials Network (HPTN) 068 study in rural South Africa from 2011 to 2017. We estimated HIV incidence under a potential intervention that reduced each risk factor and compared this to HIV incidence under the current distribution of these risk factors.

RESULTS

Although many factors had strong associations with HIV, potential intervention estimates did not always suggest large reductions in HIV incidence because the prevalence of risk factors was low. When modeling combination effects, an intervention to increase schooling, decrease depression, and decease transactional sex showed the largest reduction in incident infection (risk difference, -1.4%; 95% confidence interval [CI], -2.7% to -.2%), but an intervention on only transactional sex and depression still reduced HIV incidence by -1.3% (95% CI, -2.6% to -.2%).

CONCLUSIONS

To achieve the largest reductions in HIV, both prevalence of the risk factor and strength of association with HIV must be considered. Additionally, intervening on more risk factors may not necessarily result in larger reductions in HIV incidence.

From Survival to Glamour: Motivations for Engaging in Transactional Sex and Relationships Among Adolescent Girls and Young Women in South Africa

We explored transactional sex and relationships (TSR) among South African adolescent girls and young women (AGYW) using (1) survey data from 4,399 AGYW aged 15–24 years, and (2) qualitative data from 237 AGYW and 38 male peers. Ten percent of sexually active AGYW reported having ever had transactional sex; 14% reported having stayed in a relationship for money or material items. Factors associated with higher reporting of TSR included HIV positivity, higher food insecurity, and alcohol use. Those AGYW who were between the ages of 20–24 years (OR: 1.0; 95% CI: 0.81–1.24), had a sexual partner older than her by 5 years or more (OR: 1.89; 95% CI: 1.58–2.26), and had a transactional relationship in the past (OR: 61.1; 95% CI: 47.37–78.76) were more likely to report having transactional sex. AGYW qualitative narratives included both assertions of agency in choosing to engage in TSR, and power inequities resulting in condomless sex. Our findings can inform interventions to addressing transactional sex and relationships, critical to South Africa’s HIV response.

Syndromic surveillance of female sexually transmitted infections in primary care: a descriptive study in Monastir, Tunisia, 2007─2017

BACKGROUND

Sexually Transmitted Infections (STIs) are a public health problem, especially for reproductive-age women. The aim of this study was to determine the incidence and trend of STIs during 11 years in Tunisia (2007-17).

METHODS

We conducted a descriptive study including all women with curable STIs (chlamydia, gonorrhea, syphilis and trichomoniasis) diagnosed with the syndromic approach in all basic health care centers of the Governorate of Monastir (Tunisia) from 2007 to 2017. Syndromes included, Pelvic Pain (PP), Vaginal Discharge (VD) and Genital Ulceration (GU).

RESULTS

We analyzed 40,388 episodes of curable STIs with a crude incidence rate and age standardized incidence rate of 1393 (95% Confidence Interval (CI); 1348-1438) / 100,000 Person Year (PY) and 1328 (95%CI; 1284-1372) /100,000 PY respectively. The incidence rate showed a positive trend over 11 years for all age groups and syndromes. VD was the most common syndrome with a crude incidence rate of 1170/100,000 PY. For all syndromes, women aged 20 to 39 were the most affected age group (p < 0.001).

CONCLUSION

In conclusion, the incidence rate of STIs episodes among women diagnosed with the syndromic approach was high, consistent with the global evidence. Focusing on reviewing STIs surveillance system in low and middle-income countries could allow the achievement of the ending of STIs epidemics by 2030.

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.

Adolescents' Perceptions About Dating and Sexual Permissiveness in Ebonyi State, Nigeria: What Can Be Done to Enhance Adolescents' Sexual Health and Well-Being

Introduction: Adolescent sexual and reproductive health (SRH) issues constitute key health concerns as some adolescents are directly or indirectly involved in sexual engagements, with increased risks and health consequences. The study aims to explore adolescents' perceptions about dating and permissive sexual behaviors which will contribute to designing sexual and reproductive health interventions. This paper adds to knowledge on adolescents' perceptions about dating, pre-marital, casual, transactional and age-disparate sex in southeastern, Nigeria.

Methods: A qualitative study was undertaken in the three senatorial zones of Ebonyi state, south eastern Nigeria. The study population comprised unmarried in- and out-of-school adolescents aged 13–18 years. Data were collected using a pre-tested focus group discussion (FGD) guide. There were six FGDs for boys and six FGDs for girls. A thematic framework approach was used for data analysis.

Results: Adolescents' views about dating and other sexual behaviors were varied. The dominant view is that hugging, touching and kissing are inappropriate for unmarried adolescents. Similarly, pre-marital, casual, transactional, and age-disparate sex were viewed as unacceptable. However, some adolescents perceived pre-marital abstinence as a hindrance to the attainment of sexual satisfaction and reproductive capacity in marriage. Some boys and girls indicated that casual sex is good, because it enables girls from poor homes to socialize with more privileged boys/men, and that such relationships could lead to marriage. Some considered transactional and age-disparate sex as a means of survival from poverty and unemployment. Boys were more permissive in their views about sexual behaviors compared to the girls.

Conclusion: Adolescents' perceptions of sexual behaviors as acceptable/unacceptable vary and are gendered. This should be considered in designing innovative strategies to improve adolescents' sexual health and well-being.

Inclusive HIV Prevention in South Africa: Reaching Foreign Migrant Adolescent Girls

Within South Africa's HIV epidemic, foreign migrant adolescent girls and young women (AGYW) face unique challenges in an environment typified by xenophobia and structural inequity. The intersection of age, gender, and migrant-related factors creates threats that may exacerbate their HIV risk, including discrimination, limited social capital, and economic dependency. This paper explores HIV-related determinants of risk from the perspective of foreign migrant AGYW who participated in a Girls' Club project implemented by Community Media Trust. Within clubs, foreign migrant AGYW met weekly with a female mentor to discuss HIV, safety planning, financial literacy, and other topics. Focus group discussions (FGDs) were conducted with club members and parents to learn about pressing challenges in a context characterized by early sexual debut, high rates of teenage pregnancy, and relationships typified by material exchange. FGDs addressed HIV risk factors such as social isolation and limited access to services, exacerbated by migrant-related stigma and discrimination and lack of identity documents. The foreign migrant AGYW appreciated the role of the Girls' Clubs and mentors in helping them overcome barriers to school and health services as well as building their social and other assets. FGD results indicate that HIV prevention in South Africa should prioritize action to address the specific determinants of foreign migrant AGYW's HIV risk, as well as inclusive policies that recognize migrants' heterogeneity based on gender and age.

Seeking a "Sponyo": Insights Into Motivations and Risks Around Intergenerational Transactional Sex Among Adolescent Boys and Girls in Kenya

PURPOSE

Intergenerational transactional sex (ITS) occurs in Sub-Saharan Africa within the context of widespread poverty and limited employment opportunities. We examined how adolescents describe these relationships, why their peers engage in ITS, and what repercussions adolescents shoulder as a result.

METHODS

We conducted 14 focus group discussions with boys and girls (N = 120) aged 15-19 years in informal settlement communities in Kisumu, Kenya. We used a framework approach to guide data analysis.

RESULTS

Adolescents referred to a relatively well-off older partner in ITS relationships as a "sponsor." Poverty proved the main driver of ITS. Boys and girls noted family and peer pressure to have a "better life" via sponsors who provided for three levels of need: urgent (e.g., food), critical (e.g., school fees), and material (e.g., clothes). Adolescents described multiple risks, including "no power" to negotiate condom use. Repercussions included dropping out of school because of community stigma, "abandonment" in the event of pregnancy, and unsafe abortions.

CONCLUSIONS

Adolescents face the difficult choice between the need for money to contribute to their families' income and the discomfort and health risks of a sponsor relationship. The pressure to have a sponsor was higher among out-of-school adolescents and adolescent mothers because of heightened poverty and vulnerability. Structural interventions, such as eliminating school fees, could help reduce adolescents' perceived need to acquire sponsors. Our findings suggest a need to update guidelines for sexual and reproductive health counseling in schools and community settings to openly discuss why ITS is so commonplace and engage in risk reduction conversations with adolescents.

Transactional Sex, Alcohol Use and Intimate Partner Violence Against Women in the Rakai Region of Uganda

Transactional sex (TS) is prevalent in sub-Saharan Africa. Women's engagement in TS is linked with HIV infection; little is known about the relationship between TS, intimate partner violence (IPV) and alcohol use-established HIV risk behaviors. Using modified Poisson regression, we assessed associations between TS and physical, verbal and sexual IPV among 8248 women (15-49 years) who participated in the Rakai Community Cohort Study across forty communities in Uganda. An interaction term assessed moderation between alcohol use and TS and no significant interaction effects were found. In adjusted analysis, alcohol use and TS were significantly associated with all forms of IPV. In stratified analysis, TS was only associated with IPV in agrarian communities; alcohol use was not associated with physical IPV in trade communities or sexual IPV in trade and fishing communities. Identifying differences in IPV risk factors by community type is critical for the development of tailored interventions.

High HIV Prevalence and Low HIV-Service Engagement Among Young Women Who Sell Sex: A Pooled Analysis Across 9 Sub-Saharan African Countries

BACKGROUND

Epidemiological data are needed to characterize the age-specific HIV burden and engagement in HIV services among young, marginalized women in sub-Saharan Africa.

SETTING

Women aged ≥18 years who reported selling sex were recruited across 9 countries in Southern, Central, and West Africa through respondent driven sampling (N = 6592).

METHODS

Individual-level data were pooled and age-specific HIV prevalence and antiretroviral therapy (ART) coverage were estimated for each region using generalized linear mixed models. HIV-service engagement outcomes (prior HIV testing, HIV status awareness, and ART use) were compared among women living with HIV across age strata (18-19, 20-24, and ≥25 years) using generalized estimating equations.

RESULTS

By age 18%-19%, 45.4% [95% confidence interval (CI): 37.9 to 53.0], 5.8% (95% CI: 4.3 to 7.8), and 4.0% (95% CI: 2.9 to 5.4) of young women who sell sex were living with HIV in Southern, Central, and West Africa respectively. Prevalence sharply increased during early adulthood in all regions, but ART coverage was suboptimal across age groups. Compared with adult women ≥25, young women aged 18-19 were less likely to have previously tested for HIV [prevalence ratio (PR) 0.76; 95% CI: 0.72 to 0.80], less likely to already be aware of their HIV status (PR 0.48; 95% CI: 0.35 to 0.64), and less likely to be taking ART (PR 0.67; 95% CI: 0.59 to 0.75).

CONCLUSIONS

HIV prevalence was already high by age 18-19 in this pooled analysis, demonstrating the need for prevention efforts that reach women who sell sex early in their adolescence. ART coverage remained low, with women in the youngest age group the least engaged in HIV-related services. Addressing barriers to HIV service delivery among young women who sell sex is central to a comprehensive HIV response.

Transactional sex and HIV infection among commercial farm workers in South Africa

Background

High prevalence of HIV infection has been reported among commercial farm workers in South Africa, but studies of the role of transactional sex in this epidemic is limited.

Objective

This study seeks to examine the association between transactional sex and HIV infection among commercial farm workers in South Africa.

Methods

This is a cross-sectional secondary data analysis of the Integrated Biological and Behavioural Surveillance Survey by the International Organization of Migration among farm workers in Mpumalanga and Limpopo Provinces, South Africa in 2010. The study included 2,758 sexually active farm workers. The outcome variable was HIV infection while the main explanatory variable was engagement in transactional sex. Other explanatory variables were sex, age, marital status, number of sex partners, food security, recent history of sexually transmitted infection, condom use at last sex with non-regular partner, history of sexual violence and migration status. Bivariate and multivariable logistic regression analyses were done to obtain unadjusted and adjusted odds ratios of the association between transactional sex and HIV infection.

Results

Engagement in transactional sex was common (19%) but not significantly associated with HIV infection (OR 1.1; CI 0.57-2.44). Female sex (1.93; 1.60-2.32), age 25 to 44 years, recent STI (OR 1.37; CI 1.18-1.58) and sexual violence (OR 1.39; CI 1.19-1.63) were significant risk factors for HIV infection.

Conclusion

Risky sexual behaviours were common among the farmworker population. HIV prevention interventions should include behavioural change communication and improved access to healthcare for STI and HIV treatment.

Socioeconomic Predictors of Transactional Sex in a Cohort of Adolescent Girls and Young Women in Malawi: A Longitudinal Analysis

Transactional sex is associated with incident HIV infection among adolescent girls and young women (AGYW) in sub-Saharan Africa. Evidence on the dimensions of socioeconomic status (SES) which predict transactional sex are mixed and primarily come from cross-sectional studies. This study examined the association between SES and transactional sex in a longitudinal cohort (n = 844) of AGYW ages 15-24 years enrolled in a quasi-experimental study in Lilongwe, Malawi. Prevalence of transactional sex was 22% at baseline, 15% at 6-months and 20% at 12-months. Being divorced or widowed, being food insecure, living in a home without electricity or running water, and having few assets were associated with transactional sex. Higher educational attainment and school enrollment were protective. Having 6-7 socioeconomic risk factors increased odds of transactional sex (AOR = 4.13, 95% CI 2.45, 6.98). Structural interventions which address multiple dimensions of SES may reduce transactional sex and ultimately prevent HIV transmission among AGYW.

Conceptualization of Empowerment and Pathways Through Which Cash Transfers Work to Empower Young Women to Reduce HIV Risk: A Qualitative Study in Tanzania

Although cash transfers (CT) are hypothesized to reduce AGYW’s HIV risk, little is known about the mechanisms through which CT empower AGYW. We explored the impact of a CT intervention on AGYW’s sexual decision-making in order to describe the pathways through which the cash may influence risk behavior. The study employed qualitative methods involving: 20 longitudinal in-depth interviews (IDIs), 40 cross-sectional IDIs, 20 narrative IDIs, and two focus group discussions with AGYW ages 15–23 participating in a CT intervention. AGYW’s conceptualized empowerment as: “independence”, “hope and aspiration”. Potential pathways through which CT empowered AGYW were: economic, hope and aspiration for a better future, and access to knowledge. As a result of this empowerment, AGYW reported reductions in transactional sex, experiences of intimate partner violence, and risky-sexual behaviour. A sense of responsibility developed through economic empowerment, enhanced participants’ self-esteem and confidence in decision-making leading to changes in AGYW’s sexual risk behaviors.

Adolescents' narratives of coping with unintended pregnancy in Nairobi's informal settlements

Aim

This study explored adolescent experiences and coping strategies for unintended pregnancy in two informal settlements—Viwandani and Korogocho—in Nairobi, Kenya.

Methods

Forty-nine in-depth-interviews and eight focus group discussions were conducted with male and female adolescents aged 15–19 years from households in two informal settlements. Participants were purposively selected to include adolescents of varying socio-demographic characteristics, including the married and unmarried, and adolescents who had never/ever been pregnant. Data were transcribed, translated verbatim and analyzed thematically.

Results

Adolescents attributed unintended pregnancy to poverty, sexual violence and inconsistent contraceptive use. Lack of parental support and guidance, as well as household conflicts also exposed girls to early sexual debut and risky sexual behavior. Decisions about pregnancy management centered on carrying the pregnancy to term or terminating it. Deciding to terminate a pregnancy was not always straightforward and was motivated by concerns about stigma or shame, and school disruption. Participants reiterated that carrying an unintended pregnancy to term disrupts adolescents’ schooling, with few girls returning to school after childbirth. Upon deciding to carry a pregnancy to term, adolescents used several coping strategies such as relocating from usual residence, hiding until delivery and planning to put up the child for adoption upon delivery.

Conclusions

Early interventions to provide adolescents with comprehensive pregnancy prevention information and to address sexual violence and poverty can prevent unintended pregnancy in adolescents. Efforts to support adolescents to positively cope with unintended pregnancy and facilitate re-entry to school are also warranted.

The influence of cash transfers on engagement in transactional sex and partner choice among adolescent girls and young women in Northwest Tanzania

Cash transfers are theorised to reduce adolescent girls and young women's economic vulnerability and engagement in transactional sex; however, the processes involved remain unclear. We conducted longitudinal cross-sectional, and narrative timeline in-depth interviews with young women aged 15-23 years in northern Tanzania enrolled in a cash transfer intervention. We analysed data using a thematic approach guided by the transactional sex framework. We summarised data and compared findings to the domains of the framework. Participants reported relationships in the 'sex and material expression of love' domain characterised by emotional intimacy and loose ties between material support and sex, and the 'sex for basic needs' domain characterised by limited emotional intimacy, economic vulnerability, and a clear exchange between material support and sex. Some participants expressed that cash transfers provided business capital and savings which enabled them to decrease 'sex for basic needs'. Cash transfers influenced transactional sex engagement by altering partner selection criteria such as from an emphasis on what men could provide to a focus on relationship stability. Findings suggest that cash transfers have the potential to reduce young women's transactional relationships motivated by economic vulnerability.

"They have this not care - don't care attitude:" A Mixed Methods Study Evaluating Community Readiness for Oral PrEP in Adolescent Girls and Young Women in a Rural Area of South Africa

INTRODUCTION

Adolescent girls and young women (AGYW) remain disproportionately affected by HIV. In a rural area of South Africa with an annual incidence (2011-2015) of 5 and 7% per annum for 15-19 and 20-24-year olds respectively, oral pre-exposure prophylaxis (PrEP) could provide AGYW with a form of HIV prevention they can more easily control. Using quantitative and qualitative methods, we describe findings from a study conducted in 2017 that assessed knowledge of and attitudes toward PrEP to better understand community readiness for an AGYW PrEP rollout.

METHODS

We used descriptive analysis of a quantitative demographic survey (n = 8,414 ages 15-86) to identify population awareness and early PrEP adopters. We also conducted semi-structured, in-depth interviews with a purposive sample of 52 potential PrEP gatekeepers (health care workers, community leaders) to assess their potential influence in an AGYW PrEP rollout and describe the current sexual health landscape. Interviews were recorded, transcribed, and iteratively coded to identify major themes.

RESULTS

PrEP knowledge in the general population, measured through a demographic survey, was low (n = 125/8,414, 1.49% had heard of the drug). Medicalized delivery pathways created hostility to AGYW PrEP use. Key informants had higher levels of knowledge about PrEP and saw it as a needed intervention. Community norms around adolescent sexuality, which painted sexually active youth as irresponsible and disengaged from their own health, made many ambivalent towards a PrEP rollout to AGYW. Health care workers discussed ways to shame AGYW if they tried to access PrEP as they feared the drug would encourage promiscuity and "risky" behaviour. Others interviewed opposed provision on the basis of health care equity and feared PrEP would divert both drug and human resources from treatment programs.

CONCLUSIONS

The health system in this poor, high-HIV incidence area had multiple barriers to a PrEP rollout to AGYW. Norms around adolescent sexuality and gatekeeper concerns that PrEP could divert health resources from treatment to prevention could create barriers to PrEP roll-out in this setting. Alternate modes of delivery, particularly those which are youth-led and demedicalize PrEP, must be explored.

Predictors and Patterns of Transactional Sex with Casual Partners Among Adult Men Living in an Informal Urban Area, South Africa

Few studies have explored the relationship between transactional sex and HIV in adult men, with even fewer exploring the predictors of providing money or goods in exchange for sex. This study aimed to characterise the predictors and patterns of transactional sex in adult men in an urban informal area in South Africa. We used baseline, cross-sectional data from a study of 2406 men aged 18-40 years from an urban informal area. Past year transactional sex was assessed through questions adapted from those used previously. Controlling behaviour was measured using an adapted Sexual Relationship Power Scale. Multivariable logistic regression was used to determine associations between transactional sex and other potential explanatory variables. Nearly half (47%) of respondents who had ever had sex reported at least one type of transactional sex with a casual partner in the past year. A third of men provided support or money for a sex partner's family, 30% provided cash and 28% provided somewhere to stay. Controlling for other factors, men with higher levels of controlling behaviour had nearly double the odds of engaging in transactional sex. Men reporting three or more sexual partners had significantly higher odds of engaging in transactional sex. Hazardous drinkers had 33% higher odds of engaging in transactional sex. Men's provision of money or goods in exchange for sex with women is related to other high-risk behaviours, such as multiple sexual partners, hazardous drinking and controlling behaviour. To address transactional sex-related HIV risks, programming should address harmful masculinities, including relationship control.
