Risk perception and the influence on uptake and use of biomedical prevention interventions for HIV in sub-Saharan Africa: A systematic literature review

Women's motivations for participating in the dapivirine vaginal ring open label extension study

Open-Label Extension (OLE) studies are important in the drug development process and are used to further support the licensing applications and regulatory approvals of products. We aimed to understand why women chose to join the HOPE OLE study - where women were offered the dapivirine vaginal ring after two pivotal trials were completed - through data collected from individual in-depth interviews. Ten women at each of the six HOPE research sites in Lilongwe, Malawi; Durban (2 sites) and Johannesburg, South Africa; Kampala, Uganda; and Chitungwiza, Zimbabwe, were enrolled (n = 60). Access to an effective user-initiated HIV prevention product was one of the main reasons women joined HOPE. Although many participants worried that their male partners might expose them to HIV, they chose to remain in their relationships and avoid conflict or confrontation with their partners by discreetly using the ring to protect themselves. Other reasons for joining were quality healthcare, reimbursement and altruism. Researchers should better understand social and personal motivators behind research participation in order to recognize community sociocultural norms and its influences on product acceptability and adherence challenges.

Cofactors of Partner HIV Self-testing and Oral PrEP Acceptance Among Pregnant Women at High Risk of HIV in Kenya

BACKGROUND

Oral pre-exposure prophylaxis (PrEP) and male partner HIV self-testing (HIVST) is being scaled up within antenatal clinics. Few data are available on how co-distribution influences acceptance of both interventions.

METHODS

We used data from the PrEP Implementation of Mothers in Antenatal Care (NCT03070600) trial in Kenya. Women included in this analysis were determined to be at high risk of HIV and offered oral PrEP and partner HIVST. Characteristics were compared between women who chose: (1) PrEP and HIVST, (2) HIVST-alone, (3) PrEP-alone, or (4) declined both (reference), excluding women who had partners known to be living with HIV.

RESULTS

Among 911 women, median age was 24 years, 87.3% were married, 43.9% perceived themselves to be at high risk of HIV and 13.0% had history of intimate partner violence (IPV). Overall, 68.9% accepted HIVST and 18.4% accepted PrEP, with 54.7% accepting HIVST-alone, 4.2% PrEP-alone, and 14.3% both HIVST and PrEP. Of women accepting HIVST, partner HIV testing increased from 20% to 82% and awareness of partner HIV status increased from 4.7% to 82.0% between pregnancy and 9 months postpartum (P < 0.001). Compared with women who accepted neither, choosing: (1) HIVST-alone was associated with being married, higher level of education, and residing with partner; (2) PrEP-alone was associated with lower social support, IPV, not residing with partner, longer time living with partner, and suspicion of other partners; and (3) PrEP and HIVST was associated with being married, IPV, and suspicion that partner had other partners.

CONCLUSIONS

Understanding factors associated with accepting HIVST and PrEP can inform HIV prevention programs for pregnant women.

Translation of HIV/AIDS knowledge into behavior change among secondary school adolescents in Uganda: A review

The human immunodeficiency virus/acquired immunodeficiency syndrome (HIV/AIDS) pandemic is primarily affecting young people worldwide, with those between the ages of 15 and 24 accounting for nearly half of all new infections. This paper was written to effectively translate HIV/AIDS knowledge into actionable behavioral changes among secondary school students in Uganda by empowering them with comprehensive information, fostering a deeper understanding of preventive measures, and facilitating the development of responsible and informed decision-making skills, thereby reducing the incidence of HIV/AIDS transmission within this demographic. There is a relationship between risk perception and behavior change in HIV/AIDS prevention among high school students. This can be explained by the high proportion of secondary school students who think they are at risk of HIV infection; this perception may be related to having had early sex, being sexually active, and knowing someone has died of HIV. High school students regularly engage in risky sexual behaviors, such as not using condoms and having multiple lifelong partners. Student behavior is significantly influenced by HIV and AIDS prevention initiatives such as youth-friendly services, peer education, and condom use.

How might we motivate uptake of the Dual Prevention Pill? Findings from human-centered design research with potential end users, male partners, and healthcare providers

Introduction

Multipurpose prevention technologies (MPTs) combining contraception with HIV prevention offer a promising solution to uptake and adherence challenges faced with oral pre-exposure prophylaxis (PrEP). The Dual Prevention Pill (DPP), which combines oral PrEP with an oral contraceptive pill (OCP), could address unmet need for family planning (FP) and HIV prevention. This study aimed to identify barriers and motivators for DPP uptake to inform the development of a DPP demand generation strategy and broader introduction efforts for MPTs.

Materials and methods

Qualitative, ethnographic research employing human-centered design techniques was conducted in Kenya, South Africa, and Zimbabwe. A research consortium conducted 45 immersions, 34 key informant interviews, and 12 friendship circles with potential end users, male romantic partners, healthcare providers (HCPs), and cultural commentators. Creative concepts were subsequently co-created and validated in workshops with end users, male partners, and HCPs.

Results

Four major themes emerged. Women struggled to balance personal motivations with societal expectations. Relationship goals strongly influenced sexual and reproductive health decisions, particularly related to financial security and social status. Negative experiences, such as untrustworthy partners, were significant triggers for OCP and PrEP use. Lastly, male partners were concerned about the DPP upending gender norms but held more positive individual attitudes. Five initial audience segments for the DPP were identified: women seeking enjoyment outside of their primary relationship; new mothers adhering to social norms; women wanting to maintain romantic relationships; women at risk of unintended pregnancy; and women with unfaithful partners. Segments informed the development of three communication themes, with the preferred route highlighting the DPP as a tool to prepare for life's unpredictability.

Discussion

To effectively generate demand for the DPP, several strategies should be considered. Connecting with women's diverse identities and goals and celebrating their individuality is crucial. Linking the DPP to relationship goals reframes it as a means to protect relationships rather than a risk. Leveraging negative triggers through targeted media campaigns empowers women to take control of their sexual health during challenging moments. A balance in channel placement is necessary to raise public awareness while using more discrete channels for potentially controversial messages with male partners and wider communities.

Experience with Contraceptive Dosage Forms and Interest in Novel PrEP Technologies in Women

New pre-exposure prophylaxis (PrEP) strategies tailored to the needs and expectations of individuals at risk of HIV acquisition are needed. In the CAPRISA 082 prospective cohort study in KwaZulu-Natal, South Africa, sexually active women aged 18 to 30 reported, through interviewer-administered questionnaires, on their prior contraceptive experience and interest in both approved and potential future PrEP dosage forms (oral PrEP, long-acting injectable PrEP, and PrEP implants) between March 2016 and February 2018. Univariable and multivariable Poisson regression models with robust standard errors were used to detect associations between women's prior and current contraceptive use and interest in PrEP options. Of 425 women enrolled, 381 (89.6%) had used at least one modern female contraceptive method previously, with injectable depot medroxyprogesterone acetate (DMPA) being used by 79.8% (n = 339). Women were more likely to show interest in a future PrEP implant if they were currently using (aRR 2.1, CI 1.43-3.07, p = 0.0001) or had ever used (aRR 1.65, CI 1.14-2.40, p = 0.0087) a contraceptive implant, and were more likely to choose an implant as their first choice method than the implant-naïve (current users aRR 3.2, CI 1.79-5.73, p < 0.0001; "ever" users aRR 2.12, CI 1.16-3.86, p = 0.0142). Women were more interested in injectable PrEP if they had used injectable contraceptives (current users aRR 1.24, CI 1.06-1.46, p = 0.0088; "ever" users aRR 1.72, CI 1.20-2.48, p = 0.0033); and were more interested in oral PrEP if they had ever used oral contraceptives (aRR 1.3, CI 1.06-1.59, p = 0.0114). This apparent relationship between women's contraceptive experience and their interest in novel forms of PrEP in an equivalent dosage form may play a future role in strengthening HIV prevention efforts in women at high risk of HIV acquisition.

Exploring stakeholders perspectives on TB contact investigation in Cali, Colombia: a qualitative study

Introduction

Contact investigation is a proven intervention for tuberculosis (TB) case finding and prevention. Although widely endorsed by national public health authorities and the World Health Organization, many countries struggle to implement it effectively. The objective of the study is to describe and characterize the barriers and facilitators of TB contact investigation in Cali, Colombia from the perspective and experience of the key stakeholders involved.

Methods

We collected data from group discussions during two workshop sessions with clinic and public health staff involved in TB contact investigation (June 2019 and March 2020 respectively) and semi-structured interviews with TB cases and their household contacts (July 2019 to April 2020). We undertook an inductive thematic analysis with the RADaR technique to characterize the barriers and facilitators of the TB contact investigation process.

Results

The two workshops included 21 clinics and 12 public health staff. We also conducted 26 semi-structured interviews with TB cases and their household contacts. Using thematic analysis, we identified four common themes: Healthcare Operations, Essential Knowledge, Time Limitations and Competing Responsibilities, and Interpersonal Interactions. The main barriers to conducting household visits were low data quality, stigma and mistrust, safety concerns for health workers, and limited resources. The main barriers to TB uptake by contacts were competing responsibilities, low TB risk perceptions among contacts, and difficulty accessing diagnostic tests for contacts. In contrast, good communication and social skills among health workers and accurate TB knowledge facilitated successful household visits and TB test uptake, according to key stakeholders.

Conclusion

This study provides a deeper understanding of TB contact investigation barriers and facilitators in a high-prevalence urban setting in a middle-income country from the perspective and experience of key stakeholders. The study shed light on the barriers that hinder household contacts engagement and TB test uptake such as issues of systemic capacity and TB knowledge. Also, highlighted facilitators such as the importance of interpersonal communication skills among health workers in the public and private sector. The insights from this study can serve as a valuable resource for public health organizations seeking to enhance their contact investigation efforts and improve TB control in similar settings.

Biomedical bargains: Negotiating "safe sex" on antiretroviral treatment in rural South Africa

Wide-scale availability of antiretroviral treatment (ART) has transformed the global landscape for HIV prevention, shifting emphasis away from a strictly behavioral focus on changing sexual practices towards a biomedical approach. Successful ART management is measured by an undetectable viral load, which helps maintain overall health and prevent onward viral transmission. The latter utility of ART, however, must be understood in the context of its implementation. In South Africa, ART has become easily accessible - yet ART knowledge spreads unevenly, while counseling advice and normative expectations and experiences of gender and aging interact to inform sexual practices. As ART enters the sexual lives of middle-aged and older people living with HIV (MOPLH), a population growing rapidly, how has it informed sexual decisions and negotiations? Drawing on in-depth interviews with MOPLH on ART, corroborated with focus group discussions and national ART-related policies and guidelines, we find that for MOPLH, sexual decisions increasingly feature compliance with biomedical directives and concern for ART efficacy. Seeking consensus regarding the biological risks of sex on ART becomes an important feature of sexual negotiations, and anticipated disagreements can pre-empt sexual relationships altogether. We introduce the concept of biomedical bargains to explain what happens when disagreements arise, and the terms of sex are negotiated using competing interpretations of biomedical information. For both men and women, ostensibly gender-neutral biomedical discourses provide new discursive resources and strategies for sexual decisions and negotiations, yet biomedical bargains are still embedded in gender dynamics-women invoke the dangers of jeopardizing treatment efficacy and longevity to insist on condoms or justify abstinence, while men utilize biomedical arguments in an effort to render condomless sex safe. While the full therapeutic benefits of ART are critical for the efficacy and equity of HIV programs, they will nonetheless always affect, and be affected by, social life.

Infectious Disease Modelling of HIV Prevention Interventions: A Systematic Review and Narrative Synthesis of Compartmental Models

BACKGROUND

The HIV epidemic remains a major public health problem. Critical to transmission control are HIV prevention strategies with new interventions continuing to be developed. Mathematical models are important for understanding the potential impact of these interventions and supporting policy decisions. This systematic review aims to answer the following question: when a new HIV prevention intervention is being considered or designed, what information regarding it is necessary to include in a compartmental model to provide useful insights to policy makers? The primary objective of this review is therefore to assess suitability of current compartmental HIV prevention models for informing policy development.

METHODS

Articles published in EMBASE, Medline, Econlit, and Global Health were screened. Included studies were identified using permutations of (i) HIV, (ii) pre-exposure prophylaxis (PrEP), circumcision (both voluntary male circumcision [VMMC] and early-infant male circumcision [EIMC]), and vaccination, and (iii) modelling. Data extraction focused on study design, model structure, and intervention incorporation into models. Article quality was assessed using the TRACE (TRAnsparent and Comprehensive Ecological modelling documentation) criteria for mathematical models.

RESULTS

Of 837 articles screened, 48 articles were included in the review, with 32 unique mathematical models identified. The substantial majority of studies included PrEP (83%), whilst fewer modelled circumcision (54%), and only a few focussed on vaccination (10%). Data evaluation, implementation verification, and model output corroboration were identified as areas of poorer model quality. Parameters commonly included in the mathematical models were intervention uptake and effectiveness, with additional intervention-specific common parameters identified. We identified key modelling gaps; critically, models insufficiently incorporate multiple interventions acting simultaneously. Additionally, population subgroups were generally poorly represented-with future models requiring improved incorporation of ethnicity and sexual risk group stratification-and many models contained inappropriate data in parameterisation which will affect output accuracy.

CONCLUSIONS

This review identified gaps in compartmental models to date and suggests areas of improvement for models focusing on new prevention interventions. Resolution of such gaps within future models will ensure greater robustness and transparency, and enable more accurate assessment of the impact that new interventions may have, thereby providing more meaningful guidance to policy makers.

A novel "HIV salience and Perception" scale is associated with PrEP dispensing and adherence among adolescent girls and young women in Kampala, Uganda

Low perceived HIV risk is a barrier to effective pre-exposure prophylaxis (PrEP) use among African adolescent girls and young women (AGYW). Single-item risk perception measures are stigmatizing and alienating to AGYW and may not predict PrEP use. There is a need for a tool capturing domains of perceived HIV risk and salience that align with PrEP use among AGYW. This HIV PrEP study was conducted in Kampala, Uganda. We developed and piloted the 9-item "HIV Salience and Perception" (HPS) scale (range: 9-36); higher scores indicate beliefs of higher vulnerability to HIV. We administered the scale to Ugandan AGYW participating in an ongoing cohort study at enrollment, one, three and six months. PrEP dispensing was measured quarterly and adherence was measured daily via Wisepill (high adherence: ≥80% of expected pill bottle openings). We assessed scale performance and used generalized estimating equations to determine associations between scale score and PrEP use. Among 499 AGYW, 54.1% of our sample was ≥ 20 years (range:16-25). The median HPS score was 18 (range:8-33; α = 0.77). Higher score was associated with PrEP dispensing (aRR = 1.07 per point increase; 95% CI = 1.01-1.13; p-value = 0.02) in the overall cohort and among only those ≥ 20 years (aRR = 1.10; 95% CI = 1.03-1.19; p-value = 0.01). We did not observe an association between scale score and PrEP adherence. AGYW scoring higher on a novel HPS scale were more likely to initiate and obtain PrEP refills through 6 months. This scale may capture drivers of PrEP dispensing and could inform PrEP delivery and counseling for AGYW.

Factors influencing adolescent girls and young women's uptake of community-based PrEP services following home-based HIV testing in Eastern Cape, South Africa: a qualitative study

Home-based service delivery has been used to improve access to HIV testing and antiretroviral initiation across sub-Saharan Africa, but it has yet to be leveraged to improve pre-exposure prophylaxis (PrEP) uptake. We interviewed 37 adolescent girls and young women (AGYW) in Eastern Cape, South Africa to explore why they chose to initiate PrEP or not following home-based HIV testing and referral for PrEP, and what influenced time to PrEP initiation. Participants reported that home visits provided a source of trusted information and a way to involve family members in their PrEP initiation decisions, motivating some to start PrEP. AGYW who initiated PrEP were more likely to qualitatively perceive themselves to be at high risk for HIV compared with those who never initiated PrEP. Integrating home-based HIV testing with PrEP education and referral may be a valuable way to reduce familial barriers and boost PrEP uptake among AGYW in South Africa.

Acceptability of an intravaginal ring for simultaneously preventing HIV infection and pregnancy: Qualitative findings of the Kisumu Combined Ring Study, 2019

Multipurpose prevention technology intravaginal rings (MPT IVRs) may offer a promising solution for addressing women's multiple sexual and reproductive health needs. We describe MPT IVR acceptability perspectives and examine user experiences of 25 cisgender women aged 18-34 years enrolled in a phase IIa randomized, partially blinded, placebo-controlled evaluation of tenofovir-based IVRs with and without contraceptive co-formulation. All took part in an individual, audio-recorded, semi-structured qualitative interview. A thematic analysis of transcribed interviews was completed in MaxQDA. Participants shared little to no knowledge of or experience with IVRs prior to joining the study. Four MPT IVR themes were identified: physical well-being, method reliability, personal management, and societal endorsement. Commonly cited of concern, but less described as being experienced, were physical discomforts (e.g., painful insertion/removal; inability to carry out daily activities/chores; foreign body sensation; expulsion; sexual interference, or debilitating side effects). Uncertainty regarding efficacy influenced perspectives about intended prevention benefits. Personal choices in managing reproduction and sexual behaviors had to be congruent with sociocultural values and norms for acceptance beyond the individual user level. Participants viewed broader community acceptance as likely to be mixed given community opposition to the use of modern family planning methods. They also shared concerns that IVR use could lead to infertility, especially among nulliparous women, or that it would encourage premarital sex or high-risk sexual behaviors among adolescent and young women. While a MPT IVR may not be suitable for all women, first-hand testimonials could help influence collective receptivity. Additional community acceptability research is needed.

Making the Case for Joint Decision-Making in Future Multipurpose Prevention Technology (MPT) Choice: Qualitative Findings on MPT Attribute Preferences from the CUPID Study (MTN-045)

Introduction

Young women in sub‐Saharan Africa account for two‐thirds of all new HIV infections and face high rates of unintended pregnancy. Multipurpose prevention technologies (MPTs) are promising products under development that are designed to simultaneously prevent HIV and unintended pregnancy. Since MPTs will be used in the context of sexual relationships, ensuring acceptability and use requires understanding the role of male partners in MPT use decision‐making.

Methods

This paper draws on qualitative data from 39 couples enrolled in the Microbicide Trials Network (MTN) 045 study, conducted in 2019–2020. Partners completed a discrete choice experiment (DCE), first separately and then jointly, to measure preferences for future MPT attributes and then completed a qualitative interview. We also draw on quantitative data from interviewer observation about who dominated the decision‐making process during the joint DCE. Content analysis was used to examine (1) how couples made decisions on existing non‐MPT HIV and pregnancy prevention products; (2) how couples made decisions on future ideal‐MPT product during the DCE; and (3) how these decision‐making processes varied by decision‐making dominance (10 male, 10 female and 19 equal) and interview type (19 joint and 20 separate).

Results

Existing non‐MPT product decisions focused on trust between partners and product attributes, while future ideal‐MPT product decisions exclusively focused on product attributes. Across existing and future products, preferences for product attributes varied by gender. Male partners were most concerned with limiting side effects impacting sexual pleasure, female partners were most concerned with limiting side effects causing physical symptoms and both were concerned with the return to fertility. Across all dominance and interview types, couples reported making decisions together and female partners were often able to negotiate with male partners for their preferred product or set of product attributes.

Conclusions

Research activities in this study provided an opportunity for couples to openly present their product attribute preferences to their partner, learn about their partner's attribute preferences, negotiate for their ideal set of attributes and ultimately choose attributes that benefited the couple without disempowering the female partner. Future research should focus on the utility of couple‐based decision‐making aids or similar tools for facilitating joint MPT decision‐making.

Prevention of exposure to zoonoses in rural Latin America: Social ecological factors in a diverse regional context

Zoonotic diseases have serious impacts on human health and well-being, but they are often overlooked in rural Latin America. The design of effective preventive interventions is complex and requires an integrative approach from evidence-based information analyzed through robust theoretical frameworks. We conducted a systematized literature review and qualitative framework-guided thematic analysis to identify social ecological factors affecting the prevention and exposure to zoonotic diseases. Although resources for research are limited in Latin America, we found several studies with relevant results. We extracted and interpreted 8 themes as factors affecting the prevention, transmission, and exposure to zoonosis. These themes included knowledge and misconceptions, low risk perception, gaps in knowledge and communication, psychological effect of diseases, culture and traditions, inequality, disarticulated prevention programs, and organizational responsibility. Alongside this, we compiled and present the recommendations for actions to reduce the impact of zoonoses in these populations. The factors and recommendations here presented can be adapted to inform the design and improvement of preventive programs, focused on One Health and aiming to reduce the impact of zoonotic diseases in rural settings.

•

We identified relevant social and behavioural factors affecting the prevention of Zoonotic diseases in Latin America.

•

Knowledge, risk perceptions, and communication quality were relevant individual factors.

•

Inequity and unarticulated programs were relevant social factors.

•

Characterization of the context-specific social ecology can improve the development of effective interventions.

Alignment of PrEP adherence with periods of HIV risk among adolescent girls and young women in South Africa and Zimbabwe: a secondary analysis of the HPTN 082 randomised controlled trial

BACKGROUND

Adolescent girls and young women in southern and eastern Africa have adherence challenges with daily oral HIV pre-exposure prophylaxis (PrEP). High adherence is most important during periods of HIV risk (prevention-effective adherence). We aimed to describe HIV risk behaviour and to understand patterns in PrEP adherence during periods of risk among adolescent girls and young women from sub-Saharan Africa.

METHODS

We did a secondary analysis of the HPTN 082 trial, an open-label, interventional, randomised controlled trial of sexually active adolescent girls and young women (aged 16-25 years) testing negative for HIV in Johannesburg and Cape Town, South Africa, and in Harare, Zimbabwe. The primary outcomes were high cumulative PrEP adherence, dichotomised as intracellular tenofovir diphosphate concentrations of at least 700 fmol/punch in dried blood spots at weeks 13, 26, and 52, and high recent PrEP adherence, dichotomised as plasma tenofovir concentrations of at least 40 ng/mL at weeks 13, 26, and 52, among participants who accepted PrEP. We collected data on sexual behaviour every 3 months. We categorised visits into a binary variable of any HIV risk based on condomless sex, more than one sexual partner, primary partner's HIV status and antiretroviral use, transactional sex, drug or alcohol use around sexual activity, and laboratory-diagnosed STIs. We used generalised estimating equations to evaluate associations between HIV risk (reflecting behaviour during the previous 3 months) and high cumulative and recent adherence to PrEP and any PrEP use (quantifiable drug concentrations). The trial is registered with ClinicalTrials.gov, NCT02732730.

FINDINGS

Between Oct 12, 2016, and Oct 25, 2018, 451 women were recruited, and 427 participants (median age 21·0 years [IQR 19·0-22·0]) were eligible for inclusion in this analysis. The proportion of participants reporting at least one HIV risk factor decreased significantly over follow-up, from 364 (85%) participants at enrolment, 226 (60%) at week 13, and 243 (65%) at week 26, to 224 (61%) at week 52 (p<0·0001). Any HIV risk was significantly associated with high PrEP adherence, measured by both tenofovir diphosphate concentrations of at least 700 fmol/punch (adjusted relative risk 1·57 [95% CI 1·09-2·25]; p=0·014) and plasma tenofovir concentrations of at least 40 ng/mL (1·36 [1·11-1·65]; p=0·0025). Any HIV risk was also associated with quantifiable concentrations of tenofovir diphosphate (1·15 [1·03-1·29]; p=0·013) and tenofovir (1·27 [1·09-1·49]; p=0·0022). We observed significant dose-response relationships between number of HIV risk factors and PrEP drug concentrations.

INTERPRETATION

The association between any HIV risk and high PrEP adherence suggests that adolescent girls and young women were able to use PrEP during periods of risk, an indicator of prevention-effective PrEP adherence. Our findings support a shift in the PrEP framework to acknowledge prevention-effective adherence practices, which might improve PrEP delivery and adherence support for adolescent girls and young women in HIV-endemic settings.

HIV Risk Factors and Risk Perception Among Adolescent Girls and Young Women: Results From a Population-Based Survey in Western Kenya, 2018

BACKGROUND

In sub-Saharan Africa, HIV prevalence in adolescent girls and young women (AGYW) is 2-fold to 3-fold higher than that in adolescent boys and young men. Understanding AGYW's perception of HIV risk is essential for HIV prevention efforts.

METHODS

We analyzed data from a HIV biobehavioral survey conducted in western Kenya in 2018. Data from AGYW aged 15-24 years who had a documented HIV status were included. We calculated weighted prevalence and evaluated factors associated with outcomes of interest (HIV infection and high risk perception) using generalized linear models to calculate prevalence ratios.

RESULTS

A total of 3828 AGYW were included; 63% were aged 15-19 years. HIV prevalence was 4.5% and 14.5% of sexually active AGYW had high risk perception. Over 70% of participants had accessed HIV testing and counseling in the past 12 months. Factors associated with both HIV infection and high risk perception included having an HIV-positive partner or partner with unknown status and having a sexually transmitted infection in the past 12 months. Having an older (by ≥10 years) partner was associated with HIV infection, but not high risk perception. Less than 30% of sexually active AGYW with 3 or more HIV risk factors had high perception of HIV risk.

CONCLUSION

Gaps in perceived HIV risk persist among AGYW in Kenya. High access to HIV testing and prevention services in this population highlights platforms through which AGYW may be reached with improved risk counseling, and to increase uptake of HIV prevention strategies.

Men missing from the HIV care continuum in sub-Saharan Africa: a meta-analysis and meta-synthesis

Introduction

Men are missing along the HIV care continuum. However, the estimated proportions of men in sub‐Saharan Africa meeting the UNAIDS 95‐95‐95 goals vary substantially between studies. We sought to estimate proportions of men meeting each of the 95‐95‐95 goals across studies in sub‐Saharan Africa, describe heterogeneity, and summarize qualitative evidence on factors influencing care engagement.

Methods

We systematically searched PubMed and Embase for peer‐reviewed articles published between 1 January 2014 and 16 October 2020. We included studies involving men ≥15 years old, with data from 2009 onward, reporting on at least one 95‐95‐95 goal in sub‐Saharan Africa. We estimated pooled proportions of men meeting these goals using DerSimonion‐Laird random effects models, stratifying by study population (e.g. studies focusing exclusively on men who have sex with men vs. studies that did not), facility setting (healthcare vs. community site), region (eastern/southern Africa vs. western/central Africa), outcome measurement (e.g. threshold for viral load suppression), median year of data collection (before vs. during or after 2017) and quality criteria. Data from qualitative studies exploring barriers to men's HIV care engagement were summarized using meta‐synthesis.

Results and discussion

We screened 14,896 studies and included 129 studies in the meta‐analysis, compiling data over the data collection period. Forty‐seven studies reported data on knowledge of serostatus, 43 studies reported on antiretroviral therapy use and 74 studies reported on viral suppression. Approximately half of men with HIV reported not knowing their status (0.49 [95% CI, 0.41–0.58; range, 0.09–0.97]) or not being on treatment (0.58 [95% CI, 0.51–0.65; range, 0.07–0.97]), while over three‐quarters of men achieved viral suppression on treatment (0.79 [95% CI, 0.77–0.81; range, 0.39–0.97]. Heterogeneity was high, with variation in estimates across study populations, settings and outcomes. The meta‐synthesis of 40 studies identified three primary domains in which men described risks associated with engagement in HIV care: perceived social norms, health system challenges and poverty.

Conclusions

Psychosocial and systems‐level interventions that change men's perceptions of social norms, improve trust in and accessibility of the health system, and address costs of accessing care are needed to better engage men, especially in HIV testing and treatment.

Socio-cognitive factors influencing access to HIV prevention services among people who inject drugs in Dar es Salaam, Tanzania: An integrated bio-behavioural survey

Introduction

People who inject drugs (PWID) in Sub-Saharan Africa have limited access to comprehensive HIV services. While it is important to inform programming, knowledge about factors influencing access to comprehensive HIV services is scarce. We assessed the proportions of PWID with access to HIV prevention services and associated socio-cognitive factors in Tanzania.

Methods

A cross-sectional survey was conducted among PWID between October and December 2017 in Dar es Salaam, Tanzania. Data on access to HIV prevention services, demographics and selected socio-cognitive factors were collected through structured face-to-face interviews. Weighted descriptive and forward selection multivariable logistics regression analyses were done to assess independent associations between HIV prevention services and predictors of interest. The results were two tailed and a p-value of less than 0.05 was considered statistically significant.

Results

The study included 611 PWID (males: 94.4%) with a median age of 34 years (Interquartile Range (IQR), 29–38). A large majority of participants reported to have access to condoms (87.8%), sterile needles/syringes (72.8%) and ever tested for HIV (66.0%). About half (52.0%) reported to have used condoms in the past one month and about a third (28.5%) accessed a peer educator. The odds of testing for HIV decreased among participants who perceived their HIV risk to be high (aOR = 0.29; 95%CI: 0.17–0.49) and those experienced sexual violence (aOR = 0.60; 95%CI 0.37–0.98). However, the odds of testing for HIV increased among participants with secondary level of education (aOR = 2.16; 95%CI: 1.06–5.55), and those who reported having correct comprehensive HIV knowledge (CCHK) (aOR = 1.63; 95%CI 1.12–2.41). The odds of access to condoms increased among females (aOR = 2.23; 95%CI: 1.04–5.02) but decreased among participants with secondary level of education (aOR = 0.41; 95%CI: 0.19–0.84), an income of >TZS 200,000 (aOR = 0.39; 95%CI: 0.23–0.66) and those who perceived their HIV risk to be high (aOR = 0.13; 95%CI: 0.03–0.36). The odds of access to peer educators was higher among participants with primary (aOR = 1.61; 95%CI: 1.01–2.26), and secondary (aOR = 2.71; 95%CI: 1.39–5.33) levels of education. The odds of access to sterile needle and syringe decreased among participants who perceived their HIV risk to be high (aOR = 0.11;95%CI 0.05–0.22), and low-medium (aOR = 0.25;95%CI 0.11–0.52) but increased among those with primary level of education (aOR = 1.72;95%CI 1.06–2.78).

Conclusion

Access to condom, HIV testing, sterile needles and syringes were relatively high among PWID. However, condom use and access to peer educators was relatively low. HIV knowledge and risk perception, gender, education, and sexual violence influenced access to HIV prevention services. There is an urgent need to address the identified socio-cognitive factors and scale up all aspects of HIV prevention services to fast-track attainment of the 2025 UNAIDS goals and ending the HIV epidemic.

Public and health professional epidemic risk perceptions in countries that are highly vulnerable to epidemics: a systematic review

Background

Risk communication interventions during epidemics aim to modify risk perceptions to achieve rapid shifts in population health behaviours. Exposure to frequent and often concurrent epidemics may influence how the public and health professionals perceive and respond to epidemic risks. This review aimed to systematically examine the evidence on risk perceptions of epidemic-prone diseases in countries highly vulnerable to epidemics.

Methods

We conducted a systematic review using PRISMA standards. We included peer-reviewed studies describing or measuring risk perceptions of epidemic-prone diseases among the general adult population or health professionals in 62 countries considered highly vulnerable to epidemics. We searched seven bibliographic databases and applied a four-stage screening and selection process, followed by quality appraisal. We conducted a narrative meta-synthesis and descriptive summary of the evidence, guided by the Social Amplification of Risk Framework.

Results

Fifty-six studies were eligible for the final review. They were conducted in eighteen countries and addressed thirteen epidemic-prone diseases. Forty-five studies were quantitative, six qualitative and five used mixed methods. Forty-one studies described epidemic risk perceptions in the general public and nineteen among health professionals. Perceived severity of epidemic-prone diseases appeared high across public and health professional populations. However, perceived likelihood of acquiring disease varied from low to moderate to high among the general public, and appeared consistently high amongst health professionals. Other occupational groups with high exposure to specific diseases, such as bushmeat handlers, reported even lower perceived likelihood than the general population. Among health professionals, the safety and effectiveness of the work environment and of the broader health system response influenced perceptions. Among the general population, disease severity, familiarity and controllability of diseases were influential factors. However, the evidence on how epidemic risk perceptions are formed or modified in these populations is limited.

Conclusions

The evidence affords some insights into patterns of epidemic risk perception and influencing factors, but inadequately explores what underlies perceptions and their variability, particularly among diseases, populations and over time. Approaches to defining and measuring epidemic risk perceptions are relatively underdeveloped.

Barriers, benefits, and behaviour: Voluntary medical male circumcision ideation in a population-based sample of Zambian men

Reaching ambitious voluntary medical male circumcision (VMMC) coverage targets requires a deeper understanding of the multifaceted processes shaping men's willingness to access VMMC. Guided by the Ideation Model for Health Communication, this population-based study identifies correlates of Zambian men's future VMMC intentions. Multistage cluster sampling was used to identify households with adult men in 14 districts. Multivariable Poisson regression with robust standard errors modelled associations of future VMMC intent with ideational factors (e.g. perceived benefits and barriers) and sexual behaviours respectively. Forty per cent (40%) of uncircumcised men (N = 1 204) expressed future VMMC intentions. In multivariable analysis, VMMC intent was associated with secondary education or higher (Adjusted Prevalence Ratio [APR] 1.30, 95% Confidence Interval [95% CI]: 1.02-1.66), perceiving VMMC to increase sexual satisfaction (APR 1.45, 95% CI: 1.11-1.89), reporting distance to services as a barrier to VMMC uptake (APR = 0.54, 95% CI: 1.27-1.87), unprotected last sex (APR 1.54, 95% CI: 1.11-2.14), and ≥ 2 sexual partners in the past 12 months (APR 1.45, 95% CI: 1.05-1.99). Being aged ≥ 45 years (vs 18-24 years: APR 0.23, 95% CI: 0.13-0.40) and perceiving that circumcision: (1) is unimportant (APR 0.71, 95% CI: 0.51-0.98); (2) is incompatible with local customs (APR 0.41, 95% CI: 0.18-0.94); or (3) reduces sexual satisfaction (APR 0.10, 95% CI: 0.02-0.62) were inversely associated with future VMMC intent. Demand-creation efforts must confront salient cognitive and social barriers to VMMC uptake, including concerns around incompatibility with local customs. Simultaneously, promotional efforts should emphasise relevant VMMC benefits beyond HIV prevention that resonate with men (e.g. penile hygiene) without reinforcing harmful gender norms.

Social and behavioural research prospects for sexually transmissible infection prevention in the era of advances in biomedical approaches

In the past two decades, major advances in biomedical intervention approaches to prevent HIV and many sexually transmissible infections (STIs) have shown great promise. However, challenges to prevention remain in the area of achieving population-level impact for biomedical prevention approaches. In this paper we address what social and behavioural research approaches can contribute beyond well-known behaviour change and counselling interventions. We organise work into five areas. Adherence and disinhibition research is primarily into individual-level constructs pertaining to maximising intervention effectiveness. Coverage research represents a population-level construct germane to maximising efficient prioritisation for prevention. Research covering social determinants, a second population-level construct, contributes to both prioritisation and effectiveness. Finally, disparities and social inequities need to be incorporated into prevention, given the pervasive and persistent disparities found in rates of HIV and STIs and in their antecedents.

HIV testing and ethnicity among adolescent girls and young women aged 15-24 years in Ghana: what really matters?

Despite the high prevalence of HIV among adolescent girls and young women (AGYW) aged 15-24 years in Ghana, HIV testing remains low among this population. The objective of this study was to examine the relationship between ethnicity and HIV testing among AGYW in Ghana. The 2014 Ghana Demographic and Health Survey data were used and analyses were restricted to 3325 female participants aged 15-24 years. Chi-squared tests and a logistic regression model were used to assess the association between ethnicity and HIV testing. Furthermore, the PEN-3 cultural model informed the conceptual framework that explained the relationship between ethnicity and HIV testing behaviour. Results from the bivariate analysis showed an association between ethnicity and HIV testing among AGYW (p<0.05). However, when controlling for other behavioural and socioeconomic determinants of HIV testing in the logistic regression, there was no association between ethnicity and HIV testing. The significant predictors of HIV testing were marital status, having multiple sexual partners, and condom use. The AGYW who were married (adjusted odds ratio [aOR] = 4.56, CI: 3.46-6.08) or previously married (aOR = 4.30, CI: 2.00-9.23) were more likely to test for HIV compared with those who were never married. Having multiple sexual partners (aOR = 0.41, CI: 0.20-0.85) and condom use (aOR = 0.56, CI: 0.38-0.84) were associated with lower odds of HIV testing. The results provide evidence that ethnicity is not associated with HIV testing among AGYW in Ghana, as the bivariate association was attenuated when other behavioural and socioeconomic determinants of HIV testing were accounted for. These findings highlight the importance of considering individual-level factors, community-level factors, and other socio-cultural factors as they really matter in the development of HIV prevention programmes for adolescent girls and young women in Ghana.

Women at high risk of HIV-infection in Kampala, Uganda, and their candidacy for PrEP

Pre-exposure prophylaxis (PrEP), antiretroviral medication for prevention of HIV-acquisition, is part of biomedical HIV prevention strategies recommended for people at risk of HIV-infection. A decision to take PrEP depends on an assessment of 'being at risk' either by an individual, or healthcare provider. In this paper, we draw on the concept of 'candidacy' to examine the different ways in which women attending a dedicated clinic in Kampala, Uganda, for women at risk of HIV infection (including sex workers), assessed their suitability for PrEP. We conducted in-depth interviews with 30 HIV negative women up to four different times, to gather information on the motives for taking PrEP, and their life history and daily life. All the women described the relevance of PrEP to mitigate their risk of HIV infection. However, there were challenges to adherence because of alcohol use, irregular working hours and a fear of being seen taking pills that others might assume to be HIV treatment. The ways in which the different women used PrEP and interpreted the place of PrEP in their lives were not solely based on their assessment of protecting themselves during sex work. They also used PrEP to guard against infection from their regular partners, and as a tool to allow them to make more money safely, by having sex without a condom with clients. While eligibility to access PrEP was predicated on the women's being in an 'at risk' population group, an incentive to use PrEP was to protect themselves from HIV acquisition from a long-term partner and preserve the 'trust' in their intimate relationship by having condom-less sex. Applying a candidacy lens we highlight the complexity in how women experience and present as being 'at risk' and query the criteria on which categories of risk and PrEP eligibility are determined.

High-Risk Sexual Behavior, Binge Drinking and Use of Stimulants are Key Experiences on the Pathway to High Perceived HIV Risk Among Men Who Have Sex with Men in Brazil

In Brazil, pre-exposure prophylaxis (PrEP) is currently available for gay, bisexual, and other men who have sex with men. As PrEP use depends on an individual's perceived risk, we explored pathways by which potentially modifiable behaviors lead to high perceived HIV risk. Using online surveys (N = 16,667), we conducted a path analysis on the basis of ordered sequences of multivariate logistic regressions. High perceived HIV risk was low (26.3%) compared to condomless receptive anal sex (41.4%). While younger age increased the odds of binge drinking and of condomless receptive anal sex, it was associated with decreased odds of high perceived HIV risk. In contrast, use of stimulants increased the odds of condomless receptive anal sex and of high perceived HIV risk. Our results suggest that binge drinking and use of stimulants are key points in different pathways to high-risk sexual behavior and may lead to different perceptions of HIV risk.

Narrative sexual histories and perceptions of HIV risk among young women taking PrEP in southern Africa: Findings from a novel participatory method

Pre-exposure prophylaxis (PrEP) is an important HIV prevention method for adolescent girls and young women (AGYW) in Africa, who are at heightened risk of HIV infection. HIV risk perception is generally a powerful motivator for adoption of HIV prevention behaviours, including PrEP use. While HIV risk perceptions have been evaluated using quantitative measures, these seldom capture how individuals conceptualize and understand risk within local frameworks of meaning. More nuanced understanding may come from qualitative approaches that map these perceptions across the trajectory of sexual histories. Between 2016 and 2018, we implemented a novel participatory method to investigate risk perceptions in interviews with 32 participants in HPTN 082, a study of AGYW's use of PrEP in South Africa and Zimbabwe. Timelines were used to record narrative sexual histories and perceived HIV risk for each relationship. We found that women assessed HIV risk primarily based on their partners' personal qualities and behaviour (especially relating to infidelity); their subjective experience of being treated respectfully; and the practice of perceived 'risk reduction', including younger partners and condoms, even if used inconsistently. A narrative timeline approach grounded in an understanding of young women's sexual histories may increase critical reflection about HIV risks and facilitate risk-reduction counselling with this group.

Acceptability, safety, and patterns of use of oral tenofovir disoproxil fumarate and emtricitabine for HIV pre-exposure prophylaxis in South African adolescents: an open-label single-arm phase 2 trial

BACKGROUND

HIV incidence among adolescents in southern Africa remains unacceptably high. Pre-exposure prophylaxis (PrEP) is an effective HIV prevention intervention but there are few data on its implementation among adolescents. We aimed to investigate the safety, feasibility, and acceptability of PrEP with oral tenofovir disoproxil fumarate and emtricitabine as part of a comprehensive HIV prevention package in an adolescent population in South Africa.

METHODS

This open-label single-arm phase 2 study (PlusPills) was done in two research clinics in Cape Town and Johannesburg, South Africa. Adolescents aged 15-19 years were recruited into the study through recruitment events and outreach in the community. Potential participants were eligible for enrolment if they reported being sexually active. Exclusion criteria were a positive test for HIV or pregnancy at enrolment, breastfeeding, or any relevant co-morbidities. Participants were given oral tenofovir disoproxil fumarate and emtricitabine for PrEP to take daily for the first 12 weeks and were then given the choice to opt in or out of PrEP use at three monthly intervals during scheduled clinic visits. Participants were invited to monthly visits for adherence counselling and HIV testing during the study period. The primary outcomes were acceptability, use, and safety of PrEP. Acceptability was measured by the proportion of participants who reported willingness to take up PrEP and remain on PrEP at each study timepoint. Use was defined as the number of participants who continued to use PrEP after the initial 12-week period until the end of the study (week 48). Safety was measured by grade 2, 3, and 4 laboratory and clinical adverse events using the Division of AIDS table for grading the severity of adult and paediatric adverse events, version 1.0. Dried blood spot samples were collected at each study time-point to measure tenofovir diphosphate concentrations. This trial is registered with ClinicalTrials.gov, NCT02213328.

FINDINGS

Between April 28, 2015, and Nov 11, 2016, 244 participants were screened, and 148 participants were enrolled (median age was 18 years; 99 participants [67%] were female) and initiated PrEP. PrEP was stopped by 26 of the 148 (18%) participants at 12 weeks. Cumulative PrEP opt-out, from the total cohort, was 41% (60 of 148 participants) at week 24 and 43% (63 of 148 participants) at week 36. PrEP was well tolerated with only minor adverse events (grade 2) thought to be related to study drug, which included headache (n=4, 3%), gastrointestinal upset (n=8, 5%), and skin rash (n=2, 1%). Two participants (1%) experienced grade 3 weight loss, which was deemed related to the study drug and resolved fully when PrEP was discontinued. Tenofovir diphosphate concentrations were detectable (>16 fmol/punch) in dried blood spot samples in 108 (92%) of 118 participants who reported PrEP use at week 12, in 74 (74%) of 100 participants at week 24, and in 22 (59%) of 37 participants by the study end at week 48.

INTERPRETATION

In this cohort of self-selected South African adolescents at risk of HIV acquisition, PrEP appears safe and tolerable in those who continued use. PrEP use decreased throughout the course of the study as the number of planned study visits declined. Adolescents in southern Africa needs access to PrEP with tailored adherence support and possibly the option for more frequent and flexible visit schedules.

Sexual Health, HIV Care and Pre-exposure Prophylaxis in the African Immigrant Population: A Needs Assessment

The objective was to gain insight, from the perspective of healthcare professionals, non-medical service providers and community-based organizations working with a large majority of African immigrant patients or clients, regarding sexual health and the potential for the use of HIV PrEP in this priority population. Thirty key informants participated in a needs assessment. A questionnaire was used to obtain information through focus groups, structured interviews and by self-administration. There are cultural and linguistic barriers to engaging Africans in discussing sexual health issues. Key challenges to uptake of PrEP are multi-dimensional: socioeconomic [immigration status, housing]; cultural [talking about sex 'taboo', HIV related stigma, no concept of preventive care]; provider-related (cultural competency, inadequate PrEP education, language barrier); and individual (lack of awareness, perception of HIV risk). Meeting basic needs like housing, assuring access to care (including PrEP), community-based education, relevant training of providers, and tailored messaging are strongly recommended. Effectively addressing HIV incidence in the African-born immigrant population redonequires a multi-pronged approach.

Risk perception, public health interventions, and Covid-19 pandemic control in sub-saharan Africa

Coronavirus disease 2019 (COVID 19) has had serious social, economic, and health effects globally. The pandemic caused by severe acute respiratory syndrome coronavirus 2 (SARS-CoV- 2), which was first announced in December 2019 has resulted in more than 24 million infections. There is paucity of knowledge on the role of risk perception in the adoption of public health interventions needed to control the spread of COVID 19 infections within communities. This was a scoping review and documents how risk perception may be a major challenge for populations to adopt and implement different behavioral changes recommended to curtail the spread COVID- 19 pandemic in sub-Saharan Africa; and seeks to proffer solutions on how the identified challenges can be addressed drawing from lessons learnt from previous epidemics within the region. Database search of Google Scholar, PubMed, Research Gate among others were performed using related keywords to identify relevant journals and lists of primary articles. Culture, religious beliefs and poverty may influence how populations respond to infectious disease outbreaks. Risk strategies that focus only on biomedical approaches to control the COVID-19 pandemic may not mobilize the needed behavioral change. Lessons learnt from HIV and Ebola epidemics showed that involvement of communities could help transform weak adoption of public health measures when measures were framed in the relevant cultural context. An understanding of the factors influencing risk perception is needed to design appropriate risk communication strategies. Community engagement and reliance on local communication networks could promote mutual trust and increase the uptake of public-health interventions.

High Awareness, Yet Low Uptake, of Pre-Exposure Prophylaxis Among Adolescent Girls and Young Women Within Family Planning Clinics in Kenya

Adolescent girls and young women (AGYW) are a priority population for HIV prevention in high-burden settings. We evaluated psychosocial characteristics, behavioral risk factors for HIV, and pre-exposure prophylaxis (PrEP) awareness and uptake among AGYW seeking contraceptive services at four public sector family planning (FP) clinics offering integrated PrEP delivery in Kisumu, Kenya. From October 2018 to June 2019, we approached all AGYW (aged 15-24 years) seeking contraception to participate in a survey following receipt of FP services and PrEP screening. Overall, 470 AGYW were screened for PrEP at their FP visit by facility staff and subsequently enrolled in the survey. Median age was 22 years (interquartile range 20-23), 22% of AGYW were in school, and 55% were married. The most frequent forms of contraception were implants and injectables (41% each). Over a third of AGYW (36%) reported low social support, 13% had symptoms of moderate to severe depression, and 3% reported intimate partner violence. Three-quarters (75%) of AGYW reported recent condomless sex and 42% suspected that their primary partner had other sexual partners. Most AGYW (89%) had previously heard of PrEP; 76% had at least one PrEP eligibility criterion as per national guidelines; however, only 4% initiated PrEP at their current FP visit. PrEP initiators more frequently had high HIV risk perception than noninitiators (85% vs. 10%, p < 0.001). Low perceived HIV risk (76%) and pill burden (51%) were common reasons for declining PrEP among AGYW with HIV behavioral risk factors. PrEP counseling should be tailored to AGYW to guide appropriate PrEP decision-making in this important population.

Acceptability of oral HIV self-testing among female sex workers in Gaborone, Botswana

Background

HIV prevalence among female sex workers (FSW) in sub-Saharan Africa is much higher than in the general population. HIV self-testing (HIVST) may be useful for increasing testing rates in FSW.

Methods

We conducted semi-structured in-depth interviews among FSW, nurses and lay counsellors providing services to FSWs in Botswana. We aimed to gain understanding of perceived acceptability, anticipated barriers, and preferred approaches to HIVST among FSW. Interviews were audio-recorded, transcribed and translated. Transcripts were reviewed and coded independently by two investigators; high inter-coder agreement was achieved (Kappa = 0.80).

Results

We interviewed five care providers whose average age was 40 years (SD = 2,64, range = 37–43); three nurses and two counsellors. Thirty FSW were interviewed, with mean age 34 years (range = 20–52). Most (27; 90%) FSW expressed great interest in using HIVST kits. Facilitators of HIVST were: awareness of own risky sexual behaviours, desire to stay healthy, and perceived autonomy over one’s healthcare decisions. Perceived advantages of HIVST included convenience, privacy, and perception of decreased stigma. Identified barriers to HIVST included lack of knowledge about the HIVST kit, fear of testing due to anticipated stigma, mistrust of the test’s accuracy, doubt of self-competency to perform HIVST, and concerns about not linking to care. Assisting someone to test was noted as good for providing emotional support, but there were concerns about confidentiality breaches. Providers expressed concerns over low literacy among FSWs which could affect comprehension of testing instructions, and competency to perform testing and interpret results. Participants’ recommendations for implementation of HIVST included: ensuring wide dissemination of information on HIVST, engaging peers in information-sharing and education, making test kits accessible in FSW-friendly centres, and having clear instructions for linkage to healthcare and support.

Conclusion

HIVST shows high acceptability among FSWs in Gaborone Botswana, with providers expressing some concerns. Implementation should be peer-driven with healthcare provider oversight.

Sexual Behavior and Perceived HIV Risk Among HIV-Negative Members of Serodiscordant Couples in East Africa

HIV risk perception may influence the use of HIV prevention interventions. Using data from HIV-negative adults enrolled in a study of pre-exposure prophylaxis (PrEP) and antiretroviral therapy for HIV-serodiscordant couples in Kenya and Uganda, we examined associations between: (1) condom use and risk perception and (2) risk perception and PrEP adherence. Two-thirds of HIV-negative partners reported condomless sex with their HIV-positive partner or another partner in the month prior to study enrollment. Compared to those who reported no condomless sex, participants who reported condomless sex during the month prior to study visit had fivefold higher odds of reporting "high risk" vs "no risk" perception (36.3 versus 10.9%: aOR 4.9, 95% CI 3.4-6.9). Reporting condomless sex in the most recent sex act was associated with increased odds of perceiving some HIV risk (aOR for high risk = 7.3, 95% CI 4.9-10.8; aOR for moderate risk = 4.8, 95% CI 3.5-6.7; aOR for low risk = 3.5, 95% CI 2.7-4.6). We found no significant association between risk perception and PrEP adherence. Sexual behavior aligned with perceived HIV risk, which can facilitate an HIV-negative individual's decisions about PrEP use.

How heterogeneous are MSM from Brazilian cities? An analysis of sexual behavior and perceived risk and a description of trends in awareness and willingness to use pre-exposure prophylaxis

Background

Brazil has the largest population of individuals living with HIV/AIDS in Latin America, with a disproportional prevalence of infection among gays, bisexuals and other men who have sex with men (MSM). Of relevance to prevention and treatment efforts, Brazilian MSM from different regions may differ in behaviors and risk perception related to HIV.

Methods

We report on MSM living in 29 different cities: 26 Brazilian state capitals, the Federal District and two large cities in São Paulo state assessed in three web-based surveys (2016–2018) advertised on Grindr, Hornet and Facebook. Using logistic regression models, we assessed the association of risk behavior with HIV perceived risk as well as factors associated with high-risk behavior.

Results

A total of 16,667 MSM completed the survey. Overall, MSM from the North and Northeast were younger, more black/mixed-black, of lower income and lower education compared to MSM from the South, Southeast and Central-west. Though 17% had never tested for HIV (with higher percentages in the North and Northeast), condomless receptive anal sex (previous 6 months) and high-risk behavior as per HIV Incidence Risk scale for MSM were observed for 41 and 64%, respectively. Sexual behavior and HIV perceived risk had low variability by city and high-risk behavior was strongly associated with high HIV perceived risk. Younger age, being gay/homosexual, having a steady partner, binge drinking, report of sexually transmitted infection (STI) and ever testing for HIV were associated with increased odds of high-risk behavior. Awareness and willingness to use PrEP increased from 2016 to 2018 in most cities.

Conclusions

Overall, MSM socio-demographic characteristics were heterogeneous among Brazilian cities, but similarities were noted among the cities from the same administrative region with a marked exception of the Federal District not following the patterns for the Central-West. Combination HIV prevention is most needed among young men who self-identify as gay/homosexual, report binge drinking or prior STI.

Early resumption of sex after voluntary medical male circumcision for HIV prevention within a programmatic delivery setting in Botswana

To maximize the public health benefits of voluntary medical male circumcision (VMMC) in real-world settings, sexual abstinence is recommended for six weeks following VMMC to ensure complete wound healing. We determined the frequency and predictors of early resumption of sex among a cohort of HIV-negative, sexually active men 18–49 years who underwent VMMC within a public-sector clinic in Botswana. Multivariate robust Poisson regression methods were used to identify predictors of having any sexual intercourse in the last six weeks since undergoing VMMC. In total, 433/519 (83%) men had data available on sexual activity at six weeks post-VMMC. Median age was 27 years, 57% had a higher than secondary education, 72% were employed, and 9% were married. Overall, 122/433 (28%) men had sexual intercourse within the six weeks since VMMC, of whom 36% reported inconsistent condom use. Compared to men ≥34 years, men aged <30 years (adjusted risk ratio [aRR] = 1.71, 95% CI 0.95–3.08) and men 30–34 years had a two-fold higher likelihood of resuming sexual activity early in multivariate analyses (aRR = 2.31, 95% CI 1.26–4.25, Wald p = 0.018). Employed men were more likely to resume sexual activity early than unemployed men (aRR = 1.58, 95% CI 1.02–2.44, p = 0.039). Additional interventions are needed to encourage abstinence until complete wound healing.

Prevalence and correlates of HIV infection among people who use drugs in Cambodia: a cross-sectional survey using respondent driven sampling method

Background

Most of studies on the relationship between drug use and HIV have focused largely on people who inject drugs. Non-injecting drug use is much more common than injecting drug use, and although it can also predispose people to HIV infection, it is not widely explored. We therefore conducted this study to explore the prevalence of HIV and identify risk factors for HIV infection among people who use non-injecting drugs (PWUD) in Cambodia.

Methods

This cross-sectional study was conducted in 2017. The Respondent Driven Sampling method was used to recruit the study participants who were interviewed face-to-face using a structured questionnaire. Blood samples were collected for HIV and syphilis testing. A multivariable logistic regression analysis was conducted to identify risk factors associated with HIV infection.

Results

In total, 1367 PWUD were included in this study, whose mean age was 28.0 (SD = 7.7) years. The majority (95.1%) of the participants used methamphetamine. The prevalence of HIV was 5.7, and 35.2% of the identified HIV-positive PWUD were not aware of their status prior to the survey. After adjustment for other covariates, HIV infection remained significantly associated with being in the age group of ≥35 (AOR = 2.34, 95% CI = 1.04–6.11), having lower level of formal education of ≤ 6 years (AOR = 2.26, 95% CI = 1.04–5.15), living on the streets (AOR = 2.82, 95% CI = 1.10–7.23), perception that their HIV risk was higher as compared to that of the general population (AOR = 3.18, 95% CI = 1.27–8.62), having used injecting drugs in lifetime (AOR = 3.8, 95% CI = 1.36–4.56), and having cuts or sores around the genital area in the past 12 months (AOR = 3.42, 95% CI = 1.09–6.33).

Conclusions

The prevalence of HIV among PWUD in this study was more than 10 times higher than the prevalence in the general adult population. The findings reveal a higher vulnerability to HIV infection among specific sub-populations of PWUD, such as those who are homeless, who may benefit from tailored interventions that respond to their specific needs. To enhance HIV case finding, stratification of PWUD to facilitate HIV risk profiling based on socio-economic profiles and drug injection history is recommended.

Global PrEP roll-out: recommendations for programmatic success

Pre-exposure prophylaxis (PrEP) is being adopted and rolled out in diverse regions, communities, and groups. Although it has been shown to be effective, in some settings PrEP roll-out has lagged, in part due to flawed messaging. Lessons can be learned and principles applied from marketing to highlight the potential pitfalls of current roll-out strategies focused on selective and siloed service provision. After exploration of the way PrEP is promoted in awareness messaging (the sell), marketed to select and often stigmatised groups (the brand), and offered as a special or non-integrated service (product placement), we propose that current strategies can ultimately slow roll-out and contribute to stigma surrounding PrEP use. We propose alternatives for programmes and ministries to consider as they develop long-term plans for HIV prevention. We propose that the sell should focus on protection or wellness framing, the branding should convey PrEP as appropriate for anyone in need, and the provision of PrEP should be placed in the context of other relevant and valued health services. As has been shown in some PrEP programmes, it is possible for programmes to adopt modern marketing strategies that are attractive to healthy clients and might promote an inclusive and holistic vision of biomedical prevention.
