HIV Focused Sexual Risk-Reduction Interventions Targeting Adolescent Boys and Young Men in Sub-Saharan Africa: A Scoping Review

Adolescent girls and young women's exceptionalism with HIV interventions has left adolescent boys and young men (ABYM) trailing behind, thus becoming a marginalized and underserved population. The scoping review aimed to provide an overview of interventions that have targeted sexual risk behaviors in ABYM in Sub-Saharan Africa (SSA) over the previous 21 years with critical insights on 'what works' in preventing the sexual transmission of HIV. A scoping review guided by Arksey and O'Malley's (in Int J Soc Res Methodol 8(1):19-32, 16) framework and the 2015 Johanna Briggs Institute's guidelines was conducted. A search of literature published between 2000 and 2020 was reviewed and twenty nine interventions from nine Sub Saharan African countries that met the eligibility criteria were reviewed. The review provides evidence on the successes and the limitations of sexual risk behavior interventions for ABYM in SSA. There is clear and consistent evidence that interventions reduce sexual risk behaviors in adolescent boys and young men. Their efficiency seems to grow with the length and intensity of the intervention. Positive effects were generally observed in condom use and on measures of HIV knowledge, attitudes and sexual behaviors as well as uptake of HIV tests and voluntary male circumcision. This review shows that sexual-risk interventions engaging men and boys in SSA are promising and warrant further rigorous development in terms of conceptualization, design and evaluation.

Barriers to linkage and retention in HIV care still persist among adolescent girls and young women in western Kenya

Adolescent girls and young women (AGYW) in sub-Saharan Africa experience delayed linkage to and poor retention in HIV care. Identifying and addressing specific barriers in HIV care programming is important to achieving the upgraded UNAIDS 95-95-95 targets and epidemic control. We examined these challenges among 103 HIV-positive AGYW in and out of HIV care in communities around Lake Victoria in western Kenya as part of a larger qualitative study to identify drivers of HIV testing and HIV care utilisation in key populations. We used the social-ecological model to guide development of interview guides. Individual-level barriers included denial and forgetfulness and gendered household responsibilities, medication side effects, especially if taken without food, pills being too big and difficult to swallow and the burden of a daily medication-taking regimen. Interpersonal barriers included troubled family relationships and pervasive fears of stigma and discrimination by friends and family. Communitylevel barriers were stigmatising attitudes toward people living with HIV. Health-system barriers included negative provider attitudes and confidentiality breaches. At the structural level, participants noted high costs due to long travel times to facilities, long clinic waiting times, household food insecurity and school and work commitments. AGYW's limited decision-making autonomy due to age and gender norms, including their reliance on the authority of older adults, makes these barriers especially troubling. Innovative treatment approaches that take into account the unique vulnerabilities of AGYW are urgently needed.

Health Care Provider Decisions to Initiate Oral HIV Preexposure Prophylaxis in New York City Public Sexual Health Clinics

BACKGROUND

Oral HIV preexposure prophylaxis (PrEP) is safe and effective but underutilized. Health care providers' beliefs about PrEP and attitudes toward people who could benefit may affect PrEP access.

METHODS

This mixed-methods study (2016-2018) was conducted in 8 New York City public sexual health clinics that implemented a PrEP program. Data included 32 in-depth qualitative interviews with clinicians, quantitatively coded to reflect their PrEP beliefs; a provider questionnaire; and 6 months of medical record visit data for these providers. Among patients with a PrEP indication, we examined the odds of a patient being initiated on PrEP associated with providers' PrEP beliefs and demographic characteristics, and patient characteristics.

RESULTS

Providers reported strong support for offering PrEP to eligible patients. The majority denied concerns about possible development of drug-resistant viral strains, giving PrEP to people who might not benefit, and PrEP toxicity. Nevertheless, about one-third agreed with each of these concerns, and 55% thought PrEP use might limit condom use. Of 2176 patients with a PrEP indication, 20% were initiated. Providers with more restrictive PrEP beliefs did not have lower odds of initiating patients on PrEP. Women as well as Black and Latinx patients were less likely to be initiated on PrEP.

CONCLUSIONS

Contrary to our hypotheses, providers' negative PrEP beliefs did not seem to reduce initiation of PrEP for eligible patients. This may be attributable to clear clinical protocols, strong staff support, and training on implementing PrEP in this setting. Racial and gender disparities in PrEP uptake urgently require attention.

Implementing six multi-month dispensing of antiretroviral therapy in Ethiopia: perspectives of clients and healthcare workers

BACKGROUND

Multi-month dispensing (MMD) of antiretroviral therapy (ART) is an integral component of differentiated HIV service delivery for people living with HIV (PLHIV). Although many countries have scaled up ART dispensing to 3-month intervals, Ethiopia was the first African country to implement six-month dispensing (6-MMD) at scale, introducing its Appointment Spacing Model (ASM) for people doing well on ART in 2017. As of June 2021, 51.4% (n = 215,101) of PLHIV on ART aged ≥ 15 years had enrolled in ASM. Since little is known about the benefits and challenges of ASM perceived by Ethiopian clients and their healthcare workers (HCWs), we explored how the ASM was being implemented in Ethiopia's Oromia region in September 2019.

METHODS

Using a parallel convergent mixed-methods study design, we conducted 6 focus groups with ASM-eligible enrolled clients, 6 with ASM-eligible non-enrolled clients, and 22 in-depth interviews with HCWs. Data were audio-recorded, transcribed and translated into English. We used thematic analysis, initially coding deductively, followed by inductive coding of themes that emerged from the data, and compared the perspectives of ASM-enrolled and non-enrolled clients and their HCWs.

RESULTS

Participants enrolled in ASM and HCWs perceived client-level ASM benefits to include time and cost-savings, fewer work disruptions, reduced stigma due to fewer clinic visits, better medication adherence and improved overall health. Perceived health system-level benefits included improved quality of care, decongested facilities, reduced provider workloads, and improved record-keeping. Although non-enrolled participants anticipated many of the same benefits, their reasons for non-enrollment included medication storage challenges, concerns over less frequent health monitoring, and increased stress due to the large quantities of medicines dispensed. Enrolled participants and HCWs identified similar challenges, including client misunderstandings about ASM and initial ART stock-outs.

CONCLUSIONS

ASM with 6-MMD was perceived to have marked benefits for clients and health systems. Clients enrolled in the ASM and their HCWs had positive experiences with the model, including perceived improvements in efficiency, quality and convenience of HIV treatment services. The concerns of non-ASM enrolled participants suggest the need for enhanced client education about the model and more discreet and efficiently packaged ART and highlight that ASM is not ideal for all clients.

Condom Use Among Male Sex Workers With Their Male Clients in Mombasa, Kenya: Results of a Sub-analysis of a Pilot, Multilevel, Structural, HIV Risk-Reduction Intervention

ABSTRACT

Despite the advent of preexposure prophylaxis, consistent condom use continues to be recommended because preexposure prophylaxis does not prevent sexually transmitted infections. This is important for high-risk populations (e.g., male sex workers; MSW) in low-resource, high-HIV/sexually transmitted infection prevalence settings, such as the Mombasa region in Kenya. This study aimed to examine the relationship between MSW's condom use, and their knowledge, beliefs, and attitudes about condoms. MSW (N = 158) completed surveys on their sexual behaviors/practices/attitudes. We used multiple regressions to identify associations between condom use, HIV knowledge/attitudes, and self-efficacy. Three quarters of participants reported always using condoms in the past week, and 64.3% reported always using condoms in the past month with male clients. Mean scores for knowledge and attitudes/self-efficacy toward condoms/safer sex were positively associated with condom use. Interventions to build self-efficacy, such as condom negotiation, and/or bringing up condom use with clients may be useful for Kenyan MSW.

Evaluating effect modification by HIV testing history to understand the mechanisms behind the impact of announcing HIV self-testing availability in a clinic system in Kenya

Background

In sub-Saharan Africa, truckers and female sex workers (FSWs) have high HIV risk and face challenges accessing HIV testing. Adding HIV self-testing (HIVST) to standard of care (SOC) programs increases testing rates. However, the underlying mechanisms are not fully understood. HIVST may decrease barriers (inconvenient clinic hours, confidentiality concerns) and thus we would expect a greater impact among those not accessing SOC testing (barriers prevented previous testing). As a new biomedical technology, HIVST may also be a cue to action (the novelty of a new product motivates people to try it), in which case we might expect the impact to be similar by testing history.

Methods

We used data from two randomized controlled trials evaluating the announcement of HIVST availability via text-message to male truckers (n = 2,260) and FSWs (n = 2,196) in Kenya. Log binomial regression was used to estimate the risk ratio (RR) for testing ≤ 2 months post-announcement in the intervention vs. SOC overall and by having tested in the previous 12-months (12m-tested); and we assessed interaction between the intervention and 12m-tested. We also estimated risk differences (RD) per 100 and tested additive interaction using linear binomial regression.

Results

We found no evidence that 12m-tested modified the HIVST impact. Among truckers, those in the intervention were 3.1 times more likely to test than the SOC (p < 0.001). Although testing was slightly higher among those not 12m-tested (RR = 3.5, p = 0.001 vs. RR = 2.7, p = 0.020), the interaction was not significant (p = 0.683). Among FSWs, results were similar (unstratified RR = 2.6, p < 0.001; 12m-tested: RR = 2.7, p < 0.001; not 12m-tested: RR = 2.5, p < 0.001; interaction p = 0.795). We also did not find significant interaction on the additive scale (truckers: unstratified RD = 2.8, p < 0.001; 12m-tested RD = 3.8, p = 0.037; not 12m-tested RD = 2.5, p = 0.003; interaction p = 0.496. FSWs: unstratified RD = 9.7, p < 0.001; 12m-tested RD = 10.7, p < 0.001, not 12m-tested RD = 9.1, p < 0.001; interaction p = 0.615).

Conclusion

The impact of HIVST was not significantly modified by 12m-tested among truckers and FSWs on the multiplicative or additive scales. Announcing the availability of HIVST likely served primarily as a cue to action and testing clinics might maximize the HIVST benefits by holding periodic HIVST events to maintain the cue to action impact rather than making HIVST continually available.

Male partner age, viral load, and HIV infection in adolescent girls and young women: evidence from eight sub-Saharan African countries

OBJECTIVE

We aimed to elucidate the role of partnerships with older men in the HIV epidemic among adolescent girls and young women (AGYW) aged 15-24 years in sub-Saharan Africa.

DESIGN

Analysis of Population-based HIV Impact Assessments in Eswatini, Lesotho, Malawi, Namibia, Tanzania, Uganda, Zambia, and Zimbabwe.

METHODS

We examined associations between reported partner age and recent HIV infection among AGYW, incorporating male population-level HIV characteristics by age-band. Recent HIV infection was defined using the LAg avidity assay algorithm. Viremia was defined as a viral load of more than 1000 copies/ml, regardless of serostatus. Logistic regression compared recent infection in AGYW with older male partners to those reporting younger partners. Dyadic analysis examined cohabitating male partner age, HIV status, and viremia to assess associations with AGYW infection.

RESULTS

Among 17 813 AGYW, increasing partner age was associated with higher odds of recent infection, peaking for partners aged 35-44 (adjusted odds ratio = 8.94, 95% confidence interval: 2.63-30.37) compared with partners aged 15-24. Population-level viremia was highest in this male age-band. Dyadic analyses of 5432 partnerships confirmed the association between partner age-band and prevalent HIV infection (male spousal age 35-44-adjusted odds ratio = 3.82, 95% confidence interval: 2.17-6.75). Most new infections were in AGYW with partners aged 25-34, as most AGYW had partners in this age-band.

CONCLUSION

These results provide evidence that men aged 25-34 drive most AGYW infections, but partners over 9 years older than AGYW in the 35-44 age-band confer greater risk. Population-level infectiousness and male age group should be incorporated into identifying high-risk typologies in AGYW.

Preferences, beliefs, and attitudes about oral fluid and blood-based HIV self-testing among truck drivers in Kenya choosing not to test for HIV

Introduction

Clinical trials in sub-Saharan Africa support that HIV self-testing (HIVST) can increase testing rates in difficult-to-reach populations. However, trials mostly evaluate oral fluid HIVST only. We describe preferences for oral fluid vs. blood-based HIVST to elucidate prior trial results and inform testing programs.

Methods

Participants were recruited from a HIVST randomized controlled trial in Nakuru County, Kenya, which aimed to test the effect of choice between oral HIVST and facility-based testing compared to standard-of-care on HIV testing among truck drivers. We conducted in-depth interviews (IDIs) with purposively sampled trial participants who declined HIV testing at baseline or who were offered access to oral fluid HIVST and chose not to pick up the kit during follow-up. IDIs were conducted with all consenting participants. We first describe IDI participants compared to the other study participants, assessing the statistical significance of differences in characteristics between the two samples and then describe preferences, beliefs, and attitudes about HIVST biospecimen type expressed in the IDIs.

Results

The final sample consisted of 16 men who refused HIV testing at baseline and 8 men who did not test during follow-up. All IDI participants had tested prior to study participation; mean number of years since last HIV test was 1.55, vs. 0.98 among non-IDI participants (p = 0.093). Of the 14 participants who answered the question about preferred type of HIVST, nine preferred blood-based HIVST, and five, oral HIVST. Preference varied by study arm with four of five participants who answered this question in the Choice arm and five of nine in the SOC arm preferring blood-based HIVST. Six key themes characterized truckers' views about test type: (1) Rapidity of return of test results. (2) Pain and fear associated with finger prick. (3) Ease of use. (4) Trust in test results; (5) fear of infection by contamination; and (6) Concerns about HIVST kit storage and disposal.

Conclusion

We found no general pattern in the themes for preference for oral or blood-based HIVST, but if blood-based HIVST had been offered, some participants in the Choice arm might have chosen to self-test. Offering choices for HIVST could increase testing uptake.

"They are our eyes outside there in the community": Implementing enhanced training, management and monitoring of South Africa’s ward-based primary healthcare outreach teams

Introduction

In 2018, South Africa’s National Department of Health provided additional resources for ward-based primary healthcare outreach teams (OT) with support from the U.S. President’s Emergency Plan for AIDS Relief. The intervention package included a new training curriculum, enhanced staffing, revised management and supervisory structures, and more intensive monitoring and evaluation (M&E). The goal was to strengthen OT and their impact on both primary healthcare and HIV-specific services. We conducted a process evaluation of this intervention package during its second year and examined implementation successes and challenges.

Methods

We conducted a mixed-methods evaluation at 20 purposively selected facilities in Bojanala and City of Tshwane districts, including surveys with 222 community health workers (CHWs) and outreach team leaders (OTLs); key informant interviews and online surveys with 28 policy and program stakeholders; 70 in-depth interviews with health facility staff; 20 focus group discussions with 194 CHWs; 20 structured health facility assessments; directly-observed time-motion studies; and review of program documents.

Results

Most participants highlighted the hiring and training of CHWs and OTLs as a key implementation success because this had partially alleviated staffing shortages and helped clarify CHWs’ and OTLs’ responsibilities and supervisory structures. The new monitoring tools were welcomed for their potential to improve data collection and program tracking. However, participants highlighted many program challenges: short-lived gains in CHWs’ knowledge and skills due to lack of ongoing training and mentoring; insufficient integration of OT into health facility management structures; persistent shortages of equipment, supplies, transportation, and workspace for CHWs; and insufficient remuneration for staff.

Conclusion

Strengthening and expanding CHW programs, such as OT, requires intensive support and continuous investments. To sustain improvements in training, supervision, and job satisfaction, CHWs must be equipped with needed resources, provided with ongoing supportive supervision, and strengthened by optimized program management, monitoring and processes.

Associations Between Mobility, Food Insecurity, and Transactional Sex Among Women in Cohabitating Partnerships: An Analysis From 6 African Countries 2016-2017

BACKGROUND

Mobile women are at risk of HIV infection in sub-Saharan Africa, although we lack evidence for HIV risk among women in mobile partnerships, especially in the context of household food insecurity, a growing concern in the region.

SETTING

Women aged 15-59 years with a cohabitating male partner who participated in population-based HIV impact assessment surveys in Eswatini, Lesotho, Namibia, Tanzania, Uganda, and Zambia.

METHODS

We evaluated the association between women's and their partner's mobility (being away from home for more than 1 month or staying elsewhere) and transactional sex (selling sex or receiving money or goods in exchange for sex). We examined associations for effect measure modification by food insecurity level in the household in the past month. We used survey-weighted logistic regression, pooled and by country, adjusting for individual, partner, and household-level variables.

RESULTS

Among women with a cohabitating male partner, 8.0% reported transactional sex, ranging from 2.7% in Lesotho to 13.4% in Uganda. Women's mobility [aOR 1.35 (95% CI: 1.08 to 1.68)], but not their partner's mobility [aOR 0.91 (0.74-1.12)], was associated with transactional sex. Food insecurity was associated with transactional sex independent of mobility [aOR 1.29 (1.10-1.52)]. Among those who were food insecure, mobility was not associated with increased odds of transactional sex.

CONCLUSION

Food insecurity and women's mobility each increased the odds of transactional sex. Because transactional sex is associated with HIV risk, prevention programs can address the needs of mobile and food-insecure women, including those in cohabitating relationships.

Implementing PrEP Services in Diverse Health Care Settings

BACKGROUND

Uptake of pre-exposure prophylaxis (PrEP) in the US has been limited. Evidence for why and how PrEP has been successfully integrated into some clinical settings, but not in others is minimal. To address this gap, we conducted a qualitative study to identify contextual factors that facilitated and challenged the implementation of PrEP services.

SETTING

In partnership with the NYC Department of Health, we convened a planning committee with expertise with groups highly affected by the HIV epidemic employed in diverse health care settings, to guide the project. Representatives from programs within New York were targeted for participation initially and subsequently expanded nationally to enhance diversity in program type.

METHODS

Using an interview guide informed by the Consolidated Framework for Implementation Research, we conducted 20 interviews with participants who successfully implemented PrEP programs in different settings (eg, primary care, emergency department, sexual health clinics), using different delivery models. We used template and matrix analysis to identify and characterize contextual determinants and implementation strategies.

RESULTS

Participants frequently described determinants and strategies fluidly and conceptualized them in context-specific terms. Commonly discussed Consolidated Framework for Implementation Research constructs included implementation climate (tension for change, compatibility, relatively priority), stakeholders' knowledge (or lack thereof) and beliefs about PrEP, and costs associated with PrEP implementation.

CONCLUSION

Our work identifies patterns in PrEP program implementation, describing how organizations dealt with determinants in their own context. Our research points to the need to connect rigorous implementation research with how frontline implementers conceptualize their work to inform and improve PrEP implementation.

Effectiveness of a community-based intervention to prevent childhood TB in Lesotho

BACKGROUND: Child contact management (CCM) is a recognized strategy to prevent TB; however, implementation is suboptimal. PREVENT was a cluster-randomized trial that evaluated the effectiveness and acceptability of a community-based intervention (CBI) to improve CCM in Lesotho.METHODS: Ten health facilities (HFs) were randomized to CBI or standard-of-care (SOC). CBI included nurse training/mentorship, health education by village health workers (VHW), adherence support, and multidisciplinary team meetings. Information on TB cases registered from February 2016 to June 2018 and their child contacts was abstracted. Outcomes were TB preventive treatment (TPT) initiation, TPT completion, and CBI acceptability. Generalized linear mixed models were used to test for differences between study arms and qualitative interview thematic analysis for acceptability.RESULTS: Among 547 registered children (CBI: n = 399; SOC: n = 148) of 426 adult TB patients, 46% were <2 years, 48% female, and 3% HIV-exposed/positive, with no significant differences between study arms. A total of 501 children initiated TPT-98% at CBI and 88% at SOC HFs (P < 0.0001). TPT completion was 82% in CBI vs. 59% in SOC sites (P = 0.048). Caregivers and providers reported that CBI was acceptable.CONCLUSION: The CBI was acceptable and significantly improved TPT initiation and completion in Lesotho, offering the opportunity to mitigate the threat of TB among children.

COVID-19 vaccine uptake and factors associated with being unvaccinated among lesbian, gay, bisexual, transgender, queer, and other sexual identities (LGBTQ+) New Yorkers

Routine data on vaccine uptake are not disaggregated by lesbian, gay, bisexual, transgender, queer, and other sexual identities (LGBTQ+) populations, despite higher risk of infection and severe disease. We found comparable vaccination uptake patterns among 1032 LGBTQ+ New Yorkers and the general population. We identified critical socioeconomic factors that were associated with vaccine hesitancy in this economically vulnerable population.

Solidarity, support and competition among communities of female and male sex workers in Mombasa, Kenya

Female and male sex workers are at elevated risk for HIV infection, psychological distress and other adverse health outcomes. It is therefore important to understand how sex workers' social relationships with one another might inform psychosocial support services for this population. We conducted semi-structured interviews to examine the formation and nature of social networks of 25 female and 25 male sex workers recruited from bars and clubs in Mombasa, Kenya. Relationships between and among female and male participants were often formed based on a mutual understanding of the challenging nature of sex work. Both groups described their relationships in terms of friendship and brotherhood/sisterhood and highlighted the following benefits of sex worker social networks: economic benefits, access to information about HIV/STIs and protection, and support against violence from clients and law enforcement agents. Social networks were often threatened by competition for clients and hence could result in conflict. However, sex workers explained that their sense of solidarity and reliance on one another for health, protection and economic well-being helped minimise conflict. The social networks of sex workers could therefore be used to leverage or optimise access to HIV prevention and care.

"Being able to do whatever you wanna do as a woman is important:" a qualitative exploration of contraception as a frame of reference for HIV prevention with PrEP

Background

Use of HIV PrEP (pre-exposure prophylaxis) is a strategic tool in the effort to end the HIV epidemic. 20% of new HIV infections in the US are among cis-gender women, yet they comprise only 5% of all PrEP users. Black women disproportionately bear the burden of new HIV acquisition and accounted for almost 60% of new HIV diagnoses among women in 2018. Increasing understanding and uptake of PrEP among women at risk of HIV acquisition in alignment with their reproductive values and preferences is key to increasing PrEP uptake and decreasing HIV burden in this population.

Objective

This study examines how experiences with contraception among women of color shape their perceptions and preferences regarding HIV PrEP to inform counseling that aligns with their reproductive values.

Methods

Women aged 18–45 who self-identified as Black or Latina were recruited at an academic medical center in the Bronx from June 2018 to July 2019. We enrolled 30 participants seeking family planning care (10), prenatal care (10), or care for sexually transmitted infections (10). Participants completed a brief written survey assessing their risk of HIV acquisition. Semi-structured, face-to-face interviews were then audio-recorded, transcribed, and entered into Dedoose. Grounded theory and constant comparison approaches were used to analyze the data.

Results

Twenty-one participants (70%) screened positive for HIV acquisition risk. Four had received information on PrEP from a medical provider prior to the interview. Three themes emerged from the qualitative analysis: (1) Similar to oral contraception, women conceptualized PrEP as a “daily pill” to support their reproductive health; (2) Women perceived PrEP as a tool to support autonomy and pleasure in their sexual health; (3) Like birth control, women desired multiple delivery options for HIV prophylaxis.

Conclusions

Contraception may serve as a frame of reference when counseling about PrEP among cis-women at risk of acquiring HIV. Our study suggests that this approach re-contextualizes counseling on PrEP within a sex-positive framework that prioritizes pleasure, safety, and autonomy as integral to sexual and reproductive wellness. Consideration of historically marginalized women’s experiences with contraception and reproductive values may facilitate their use of PrEP.

PrEP (pre-exposure prophylaxis) is a medicine taken daily by people at risk of getting HIV from sex or injection drug use. Although PrEP is a safe and effective medication for women, the use of PrEP remains exceedingly low among cis-gender women at risk of HIV in the US. This study examines how experiences with contraception among women of color, who disproportionately bear the burden of HIV acquisition, shape their perceptions and preferences regarding PrEP. We interviewed 30 women who self-identified as Black or Latina at an academic medical center in the Bronx. Similar to oral contraception, women in this study conceptualized PrEP as a “daily pill” to support their reproductive health. This report details how women’s experiences with contraception may serve as the foundation to re-contextualize conversations on PrEP within a sex-positive framework that prioritizes pleasure, safety, and autonomy as integral to sexual and reproductive wellness.

Stigma, Social Cohesion, and HIV Risk Among Sexual and Gender Minorities in Two Cities in Zimbabwe

Though stigma is a recognized contributor to the disproportionate HIV burden among sexual and gender minorities (SGM) in sub-Saharan Africa, data describing this association among Zimbabwean SGM are limited. We examined relationships between SGM stigma and HIV and the potential for social cohesion to moderate the association among Zimbabwean men who have sex with men, transgender women, and genderqueer individuals. Consenting participants (n = 1511) recruited through respondent-driven sampling for a biobehavioral survey in Harare and Bulawayo completed structured interviews and received HIV testing. Reported SGM stigma was common (68.9% in Harare and 65.3% in Bulawayo) and associated with HIV infection in Harare (adjusted prevalence ratio [aPR] = 1.82, 95% confidence interval [CI] = 1.27–2.62) and Bulawayo (aPR = 1.51, 95% CI = 1.15–2.00) in relative risk regression. Social cohesion did not moderate these relationships. Findings demonstrate stigma’s association with HIV vulnerability among Zimbabwean SGM, highlighting the need for stigma-mitigation to reduce HIV transmission in this population.

Women Trust Their OBGYNs to Provide Preexposure Prophylaxis: An Opportunity for HIV Prevention

Objective

The objective of this study was to understand how women perceive the role of their Obstetrician and Gynecologist (OBGYN) in screening for and providing preexposure prophylaxis (PrEP) for HIV prevention.

Methods

We recruited women ages 18–45 years receiving obstetric or gynecological care at an academic medical center in the Bronx, NY. Thirty participants were enrolled: 10 seeking care for family planning, 10 seeking prenatal care, and 10 seeking care for a sexually transmitted infection. We screened participants for HIV acquisition risk using a PrEP screening tool. We conducted face-to-face, semi-structured interviews, which were audio-recorded, transcribed, and entered into Dedoose for analysis of themes using a grounded theory approach.

Results

Sixty percent of the participants were Latinx and 33% African American. Seventy percent had one or more risk factors for HIV acquisition based on the PrEP screening tool, indicating they would benefit from a PrEP discussion. Three main themes emerged from the analysis of interview data. Participants viewed OBGYNs as experts in sexual and reproductive healthcare and believed they were experts in PrEP. Participants were concerned about “PrEP stigma”, being judged by their clinicians as being sexually promiscuous if they expressed a need for PrEP. Lastly, when participants trusted their OBGYN, that trust became a facilitator for women to consider PrEP and offset stigma as a barrier to identifying patients who are candidates for PrEP.

Conclusion

Women established in care with an OBGYN are enthusiastic about having access to PrEP services incorporated into their sexual and reproductive healthcare. A universal approach to HIV prevention would avert stigma surrounding HIV care and prevention.

Violence and Victimization in Interactions Between Male Sex Workers and Male Clients in Mombasa, Kenya

Male sex workers (MSWs) and male clients (MCMs) who engage their services face increased vulnerability to violence in Kenya, where same-sex practices and sex work are criminalized. However, little is known about how violence might arise in negotiations between MSWs and MCMs. This study explored the types of victimization experienced by MSWs and MCMs, the contexts in which these experiences occurred, and the responses to violence among these groups. We conducted in-depth interviews with 25 MSWs and 11 MCMs recruited at bars and clubs identified by peer sex worker educators as "hotspots" for sex work in Mombasa, Kenya. Violence against MSWs frequently included physical or sexual assault and theft, whereas MCMs' experiences of victimization usually involved theft, extortion, or other forms of economic violence. Explicitly negotiating the price for the sexual exchange before having sex helped avoid conflict and violence. For many participants, guesthouses that were tolerant of same-sex encounters were perceived as safer places for engaging in sex work. MSWs and MCMs rarely reported incidents of violence to the police due to fear of discrimination and arrests by law enforcement agents. Some MSWs fought back against violence enacted by clients or tapped into peer networks to obtain information about potentially violent clients as a strategy for averting conflicts and violence. Our study contributes to the limited literature examining the perspectives of MSWs and MCMs with respect to violence and victimization, showing that both groups are vulnerable to violence and in need of interventions to mitigate violence and protect their health. Future interventions should consider including existing peer networks of MSWs in efforts to prevent violence in the context of sex work. Moreover, decriminalizing same-sex practices and sex work in Kenya may inhibit violence against MSWs and MCMs and provide individuals with safer spaces for engaging in sex work.

'How come they don't talk about it in school?' Identifying adolescent barriers to PrEP use

Although 21% of new human immunodeficiency virus (HIV) diagnoses in the United States are in youth aged 13-24 years, adolescent awareness and uptake of the HIV prevention medication pre-exposure prophylaxis (PrEP) are low. This study explores the attitudes and challenges that adolescents face while taking PrEP. Thirty interviews were conducted with Black and Latine (we use the gender-inclusive term Latine rather than Latinx for more appropriate Spanish pronunciation) students aged 15-17 who received care at school-based health centers (SBHCs) in the Bronx, NY. Transcripts were coded inductively and deductively using thematic analysis. Most participants were unaware of PrEP, but nearly all were enthusiastic when informed about it; a majority denied that they would feel any stigma when taking PrEP. Despite this high receptivity, multiple barriers were identified, particularly confidentiality from parents, low perceived need of PrEP and concerns about daily adherence and side effects. Adolescents overall were enthusiastic about the availability of PrEP and felt it empowered them to have control over their health. SBHCs were considered trusted sources of confidential, accessible care, and we believe that they can be uniquely positioned to mitigate barriers to PrEP distribution in the future.

Paediatric tuberculosis preventive treatment preferences among HIV-positive children, caregivers and healthcare providers in Eswatini: a discrete choice experiment

OBJECTIVE

Isoniazid preventive therapy initiation and completion rates are suboptimal among children. Shorter tuberculosis (TB) preventive treatment (TPT) regimens have demonstrated safety and efficacy in children and may improve adherence but are not widely used in high TB burden countries. Understanding preferences regarding TPT regimens' characteristics and service delivery models is key to designing services to improve TPT initiation and completion rates. We examined paediatric TPT preferences in Eswatini, a high TB burden country.

DESIGN

We conducted a sequential mixed-methods study utilising qualitative methods to inform the design of a discrete choice experiment (DCE) among HIV-positive children, caregivers and healthcare providers (HCP). Drug regimen and service delivery characteristics included pill size and formulation, dosing frequency, medication taste, treatment duration and visit frequency, visit cost, clinic wait time, and clinic operating hours. An unlabelled, binary choice design was used; data were analysed using fixed and mixed effects logistic regression models, with stratified models for children, caregivers and HCP.

SETTING

The study was conducted in 20 healthcare facilities providing TB/HIV care in Manzini, Eswatini, from November 2018 to December 2019.

PARTICIPANTS

Ninety-one stakeholders completed in-depth interviews to inform the DCE design; 150 children 10-14 years, 150 caregivers and 150 HCP completed the DCE.

RESULTS

Despite some heterogeneity, the results were fairly consistent among participants, with palatability of medications viewed as the most important TPT attribute; fewer and smaller pills were also preferred. Additionally, shorter waiting times and cost of visit were found to be significant drivers of choices.

CONCLUSION

Palatable medication, smaller/fewer pills, low visit costs and shorter clinic wait times are important factors when designing TPT services for children and should be considered as new paediatric TPT regimens in Eswatini are rolled out. More research is needed to determine the extent to which preferences drive TPT initiation, adherence and completion rates.

The Impact on HIV Testing Over 6 Months When Free Oral HIV Self-Test Kits Were Available to Truck Drivers in Kenya: A Randomized Controlled Trial

Background: Studies suggest that offering HIV self-testing (HIVST) increases short-term HIV testing rates, but few have looked at long-term outcomes. Methods: We conducted a randomized controlled trial (RIDIE 55847d64a454f) on the impact of offering free oral HIVST to 305 truck drivers recruited from two clinics in Kenya. We previously reported that those offered HIVST were more likely to accept testing. Here we report on the 6-month follow-up during which intervention participants could pick-up HIVST kits from eight clinics. Results: There was no difference in HIV testing during 6-month follow-up between participants in the intervention and the standard of care (SOC) arms (OR = 1.0, p = 0.877). The most common reasons given for not testing were lack of time (69.6%), low risk (27.2%), fear of knowing HIV status (20.8%), and had tested recently (8.0%). The null association was not modified by having tested at baseline (interaction p = 0.613), baseline risk behaviors (number of partners in past 6 months, interaction p = 0.881, had transactional sex in past 6 months, interaction p = 0.599), nor having spent at least half of the past 30 nights away from home for work (interaction p = 0.304). Most participants indicated a preference for the characteristics associated with the SOC [preference for blood-based tests (69.4%), provider-administered testing (74.6%) testing in a clinic (70.1%)]. However, those in the intervention arm were more likely to prefer an oral swab test than those in the SOC (36.6 vs. 24.6%, p = 0.029). Conclusions: Offering HIVST kits to truck drivers through a clinic network had little impact on testing rates over the 6-month follow-up when participants had to return to the clinic to access HIVST. Clinic-based distribution of HIVST kits may not address some major barriers to testing, such as lack of time to go to a clinic, fear of knowing one's status and low risk perception. Preferred HIV testing attributes were consistent with the SOC for most participants, but oral swab preference was higher among those in the intervention arm, who had seen the oral HIVST and had the opportunity to try it. This suggests that preferences may change with exposure to different testing modalities.

HIV and aging among adults aged 50 years and older on antiretroviral therapy in Eswatini

Background: Antiretroviral therapy (ART) has decreased HIV-related morbidity and mortality and increased life expectancy of people living with HIV (PLHIV). Globally, the number of older PLHIV (OPLHIV; ≥50 years) is growing and predicted to increase substantially in coming years. In sub-Saharan Africa, where the majority of OPLHIV reside, there are limited data on the health and well-being of OPLHIV.Methods: We conducted an exploratory descriptive study that included structured interviews with 50 OPLHIV receiving ART at an outpatient HIV clinic in Eswatini and in-depth qualitative interviews (IDIs) with a sub-set of ten participants to elicit their experiences of living with HIV as an older adult, including quality of life, physical health, and mental health. Quantitative analyses were performed to obtain both descriptive statistics and cross-tabulations. A thematic analysis of IDI narratives was conducted based on three levels of the socio-ecological model to identify sub-themes and response patterns.Results: All study participants were virally suppressed. Self-reported non-communicable disease (NCD) risk factors and markers were common, with 40% (n = 20) reporting being current or former smokers, 0% consuming the recommended servings of fruits and vegetables per day, and 57% (n = 28 of 49 reporting screening) reporting having hypertension. However, the majority (88%; 44 of 50) had sufficient physical activity; most of the activity was in the work domain. Slightly more than one-third (38%; 13 of 34 tested) had a high random blood sugar level. Barriers to living with HIV were primarily structural (food insecurity, unemployment, access to transportation and health care).Conclusions: OPLHIV should be screened for NCDs, and services for NCDs should ideally be integrated with HIV services. While all participants had controlled HIV, this study highlights the need for strategies that facilitate OPLHIV's HIV service utilisation. With the increasing numbers of OPLHIV, these issues cannot be ignored.

Improving child tuberculosis contact identification and screening in Lesotho: Results from a mixed-methods cluster-randomized implementation science study

Background

Child tuberculosis (TB) contact management is recommended for preventing TB in children but its implementation is suboptimal in high TB/HIV-burden settings. The PREVENT Study was a mixed-methods, clustered-randomized implementation study that evaluated the effectiveness and acceptability of a community-based intervention (CBI) to improve child TB contact management in Lesotho, a high TB burden country.

Methods

Ten health facilities were randomized to CBI or standard of care (SOC). CBI holistically addressed the complex provider-, patient-, and caregiver-related barriers to prevention of childhood TB. Routine TB program data were abstracted from TB registers and cards for all adult TB patients aged >18 years registered during the study period, and their child contacts. Primary outcome was yield (number) of child contacts identified and screened per adult TB patient. Generalized linear mixed models tested for differences between study arms. CBI acceptability was assessed via semi-structured in-depth interviews with a purposively selected sample of 20 healthcare providers and 28 caregivers. Qualitative data were used to explain and confirm quantitative results. We used thematic analysis to analyze the data.

Results

From 01/2017-06/2018, 973 adult TB patients were recorded, 490 at CBI and 483 at SOC health facilities; 64% male, 68% HIV-positive. At CBI and SOC health facilities, 216 and 164 child contacts were identified, respectively (p = 0.16). Screening proportions (94% vs. 62%, p = 0.13) were similar; contact yield per TB case (0.40 vs. 0.20, p = 0.08) was higher at CBI than SOC health facilities, respectively. CBI was acceptable to caregivers and healthcare providers.

Conclusion

Identification and screening for TB child contacts were similar across study arms but yield was marginally higher at CBI compared with SOC health facilities. CBI scale-up may enhance the ability to reach and engage child TB contacts, contributing to efforts to improve TB prevention among children.

Life in the Balance: Young Female Sex Workers in Kenya Weigh the Risks of COVID-19 and HIV

The COVID-19 pandemic has had serious health, economic and psychosocial consequences. Marginalized populations including female sex workers face the stark choice of risking exposure to SARS-CoV-2 as they engage with clients or prioritizing their health at the cost of losing a primary source of income. As part of an ongoing open-label, randomized controlled trial providing daily oral pre-exposure prophylaxis and adherence support, we interviewed 193 of 200 enrolled young female sex workers (18–24 years) in Kisumu, Kenya, about COVID-19 awareness and precautions, access to health services, and sex work during Kenya’s pandemic-related lockdown. Nearly all participants were aware of COVID-19 and reported taking protective measures, but only half reported concerns about acquiring SARS-CoV-2. Night curfews and bar closures adversely affected participants’ sex work business, reducing the number of clients and payment amounts from clients. Nearly 15% experienced violence from a client or regular, non-paying sex partner during the lockdown period. Participants’ access to healthcare services was not disrupted.

Perceived male partner attitudes toward the female condom predict female university students' use of the female condom

Female and male condoms are the only methods that prevent both sexually transmitted infections (STIs), including HIV, and unintended pregnancy. Despite continuing high STI rates, few studies investigate factors predicting whether women initiating female condom (FC) use sustain use. Using data from a randomized trial, we examined predictors of sustained FC use at five-month follow-up (FU2) among female university students in South Africa who participated in either a one-session, information-only, group-delivered Minimal Intervention or a two-session, group-delivered Enhanced Intervention. In the final multiple logistic regression model, believing one's partner holds positive attitudes toward the FC (aOR = 1.40; p = 0.028), and greater FC use for vaginal sex at previous assessment (aOR) = 1.19; p = 0.008) were associated with greater odds of FC use at FU2. Excluding number of FC-protected occasions at FU1 from the analysis, discussing FC use with partner (aOR = 2.89; p = 0.071) and believing one's partner holds positive attitudes toward the FC (aOR = 1.63; p < 0.001) were associated with greater odds of use at FU2. The FC empowers women to protect themselves from both STIs and unintended pregnancy, but targeted interventions are needed to address men's negative attitudes toward the device. Engaging men as FC champions to support and promote FC use, along with marketing campaigns targeted to men, may expand FC coverage and enhance uptake.
