What leads some people to think they are HIV-positive before knowing their diagnosis? A systematic review of psychological and behavioural correlates of HIV-risk perception

Factors Associated with Low/Moderate Perceived Risk for HIV Acquisition Among Gay, Bisexual, and Other Men Who Have Sex with Men Eligible to Use Pre-exposure Prophylaxis from Brazil, Mexico, and Peru

Perceived risk for HIV acquisition among gay, bisexual, and other men who have sex with men (GBMSM) may not align with their actual sexual HIV exposure. Factors associated with low/moderate perceived risk among GBMSM eligible for pre-exposure prophylaxis (PrEP) (based on their high estimated HIV exposure) have been poorly described in Latin America. This is a secondary analysis of a 2018 web-based cross-sectional survey in Brazil, Mexico, and Peru. Participants were ≥ 18 years old, cisgender men, not living with HIV, had sex with other men in the previous six months, and had an HIV Incidence Risk Index for MSM score ≥ 10. We performed a multivariable logistic regression to identify factors associated with low/moderate perceived risk for HIV acquisition for each country. A total of 9900 GBMSM were included, and the majority (85.7%) reported low/moderate perceived risk for HIV acquisition. The mean age was 28.8 (SD = 7.7) years, and 77.7% had high school or more. Having ≥ 5 sex partners, daily use of geosocial networking (GSN) apps, and having sex (including condomless insertive anal sex) with a person living with HIV decreased the odds of low/moderate perceived risk for HIV acquisition, but an HIV test in the last year increased the odds only in Mexico. Latin GBMSM with high sexual HIV exposure (eligible to use PrEP) showed a massive gap with their perceived risk. HIV prevention counseling should explore HIV testing history and the frequency of use of GSN apps to promote an objective self-assessment of HIV exposure among Latin GBMSM.

" I Look in the Mirror and Say ' You Know What, There Is Hope for You '"-An Interpretative Qualitative Study of Current and Future Well-Being in Black African Women Older Than 50 Years With HIV in the United Kingdom

ABSTRACT

Effective antiretroviral treatment means that people with HIV are living for longer. This includes Black African women, who represent a large proportion of people aging with HIV in the United Kingdom. Despite this, the impact of living and aging with HIV on the well-being of Black African women aging with HIV has not been investigated. Interpretative phenomenological analysis of interviews with eight Black African women ages 50 years and older living with HIV developed six superordinate themes. Findings demonstrated how experiences of HIV-related stigma negatively affected social, occupational, and psychological well-being. Perspectives on living and aging with HIV into the future included experiences of acceptance, uncertainty, anxiety, and hope. Recommendations are made, including developing clinical practice to consider needs relating to social and psychological well-being, as well as physical well-being, for women aging with HIV.

Men who have sex with men perceiving that sex with women carries the greatest risk of HIV acquisition: results from a mixed-methods systematic review in sub-Saharan Africa

INTRODUCTION

In sub-Saharan Africa (SSA), men who have sex with men (MSM) often have female sexual partners. Their overall risk of acquiring HIV is higher with male partners. Risk perception is associated with HIV knowledge, sexual risk and preventive behaviours. This synthesis aimed to summarize existing data about HIV knowledge and perceived HIV acquisition risk regarding sex with men and with women in MSM in SSA.

METHODS

We conducted a systematic literature review of MSM's relationships with women in SSA (PROSPERO-CRD42021237836). Quantitative and qualitative data related to MSM's perceived risk from sex with men and with women and HIV knowledge (published up to 2021) were selected and synthesized.

RESULTS

Twenty studies were selected. More MSM perceived that the greatest risk of HIV acquisition came from heterosexual/vaginal sex than from homosexual/anal sex (53% vs. 15%; 51% vs. 39%; 42% vs. 8%; 27% vs. 25%; 43% vs. 11%; 23% vs. 13%; 35% vs. 16%, cumulative sample n = 4396, six countries). A higher proportion of MSM received preventive information on heterosexual HIV transmission than on homosexual transmission (79% vs. 22%; 94% vs. 67%; 54% vs. 19%; cumulative sample n = 1199, four countries). The qualitative synthesis (eight studies) highlighted biology- and behaviour-based misconceptions leading MSM to perceive lower or negligible HIV risk from sex with men, compared to sex with women. These misconceptions were partly fuelled by the predominant focus on heterosexual and vaginal HIV transmission in HIV prevention information.

DISCUSSION

Common misconceptions regarding sexual risk between men remain unaddressed by the heteronormative messaging of HIV prevention. Underestimation by MSM of their HIV acquisition risk with male partners can pose significant barriers to effective HIV preventive behaviours and strengthen the transmission risk from MSM to their female partners.

CONCLUSIONS

Improving access of MSM to tailored HIV prevention information and tools that address their practices with male and female partners is crucial. Integrating messages about anal sex into broader public health initiatives, including sexual health programmes targeting the general population, is essential. Further research in diverse settings in SSA is necessary to gain a greater understanding of the drivers and implications of HIV risk perception in MSM.

HIV Treatment Optimism Moderates the Relationship between Sexual Risk Behavior and HIV Risk Perception among Urban HIV-negative Gay, Bisexual, and Other Men who have Sex With Men

Using baseline data of the Engage Cohort Study, a Canadian study of sexually active gay, bisexual and other men who have sex with men (GBM), we evaluated the association between sexual behavior and risk perception among HIV-negative participants and whether HIV treatment optimism moderated this relationship. Participants were recruited by respondent-driven-sampling (RDS). We defined high-risk sexual behavior in the past six months as any condomless anal sex with a casual partner (i.e. not the participant's main partner) with either unknown HIV-status where neither used pre-exposure prophylaxis or with a partner living with HIV having detectable/unknown viral load. We assessed HIV treatment optimism-skepticism using a 12-item scale. RDS-II-weighted adjusted logistic regression models examined associations with risk perception measured by the question "How would you assess your current risk of getting HIV?" (response options were on a 6-point Likert-scale ranging from "very unlikely" to "very likely", dichotomized into "No Perceived Risk" (very unlikely/unlikely) and "Perceived Risk" (somewhat likely/likely/very likely/I think I already have HIV). Of 1961 participants, engagement in high-risk sexual behavior was reported by 155 (17.0%), 62 (12.4%), 128 (17.2%) of participants in Montréal, Toronto, and Vancouver, respectively. High-risk sexual behavior increased the odds of perceived HIV risk (pooled adjusted odds ratio = 2.9, 95%CI = 2.2-3.8). HIV treatment optimism-skepticism scores moderated the relationship: for GBM engaging in high-risk sexual behavior, higher HIV treatment optimism-skepticism scores increased perceived HIV risk. Promoting awareness around advances related to HIV prevention and treatment is important for appropriate risk assessment and for increased engagement in prevention interventions.

Moderating Effect of Pre-Exposure Prophylaxis Use on the Association Between Sexual Risk Behavior and Perceived Risk of HIV Among Brazilian Gay, Bisexual, and Other Men Who Have Sex With Men: Cross-Sectional Study

BACKGROUND

Gay, bisexual, and other men who have sex with men (MSM) with a higher perceived risk of HIV are more aware of and willing to use pre-exposure prophylaxis (PrEP). PrEP is an effective HIV prevention strategy, but there is a lack of data on how PrEP use might moderate the relationship between sexual risk behavior and perceived risk of HIV. Moreover, most studies measure perceived risk of HIV via a single question.

OBJECTIVE

We estimated the moderating effect of PrEP use on the association between sexual risk behavior and perceived risk of HIV, measured with the 8-item Perceived Risk of HIV Scale (PRHS), among Brazilian MSM.

METHODS

A cross-sectional, web-based survey was completed by Brazilian Hornet app users aged ≥18 years between February and March 2020. We included data from cisgender men who reported sex with men in the previous 6 months. We evaluated the moderating effect of current PrEP use on the association between sexual risk behavior, measured via the HIV Incidence Risk Index for MSM (HIRI-MSM), and perceived risk of HIV, measured by the PRHS. Higher HIRI-MSM (range 0-45) and PRHS (range 10-40) scores indicate greater sexual behavioral risk and perceived risk of HIV, respectively. Both were standardized to z scores for use in multivariable linear regression models.

RESULTS

Among 4344 cisgender MSM, 448 (10.3%) were currently taking PrEP. Current PrEP users had a higher mean HIRI-MSM score (mean 21.0, SD 9.4 vs mean 13.2, SD 8.1; P<.001) and a lower mean PRHS score (mean 24.6, SD 5.1 vs mean 25.9, SD 4.9; P<.001) compared to those not currently taking PrEP. In the multivariable model, greater HIRI-MSM scores significantly predicted increased PRHS scores (β=.26, 95% CI 0.22-0.29; P<.001). PrEP use moderated the association between HIRI-MSM and PRHS score (interaction term β=-.30, 95% CI -0.39 to -0.21; P<.001), such that higher HIRI-MSM score did not predict higher PRHS score among current PrEP users.

CONCLUSIONS

Our results suggest current PrEP users have confidence in PrEP's effectiveness as an HIV prevention strategy. PrEP's effectiveness, positive psychological impact, and the frequent HIV testing and interaction with health services required of PrEP users may jointly influence the relationship between sexual risk behavior and perceived risk of HIV among PrEP users.

How is Aging Perceived to Affect Well-being in Women Older than 50 Years Living With HIV? A Qualitative Systematic Review

ABSTRACT

Advances in HIV treatment have led to more people with HIV living to 50 years and older. No reviews have qualitatively analyzed and synthesized the literature relevant to theory and practice for well-being specifically in Women living with HIV (WLWH) aged 50 years and older. Sixteen eligible qualitative studies were critically appraised and thematically synthesized to investigate how aging was perceived to affect well-being in WLWH aged 50 years and older. Six themes demonstrated how HIV-related stigmas negatively affected social well-being, and how adjusting to living and aging with HIV negatively affected psychological and physical well-being of older WLWH. Holding caring roles also negatively affected physical well-being of WLWH. Globally, majority women aging with HIV were found to experience additional stigmas. Further research could elucidate how HIV-related stigma affects the well-being of global majority women living and aging with HIV. Recommendations are made for future HIV-related clinical practice and theory development.

Assessing the Underestimation of HIV Risk Infection among Young Men Who Have Sex with Men in Argentina

The aim of this study is to describe the discordance between the self-perceived risk and actual risk of HIV among young men who have sex with men (YMSM) and its associated factors. An online, cross-sectional study was conducted with 405 men recruited from an Argentinian NGO in 2017. Risk discordance (RD) was defined as the expression of the underestimation of risk, that is, as a lower self-perception of HIV risk, as measured with the Perceived Risk of HIV Scale, than the current risk of HIV infection, as measured by the HIV Incidence Risk Index. Multivariate logistic regression models were used to analyze the associations between the RD and the explanatory variables. High HIV risk was detected in 251 (62%), while 106 (26.2%) showed high self-perceived risk. RD was found in 230 (56.8%) YMSM. The predictors that increased RD were consistent condom use with casual partners (aOR = 3.8 [CI 95:1.5-11.0]), the use of Growler to meet partners (aOR = 10.38 [CI 95:161-121.94]), frequenting gay bars (aOR = 1.9 [95% CI:1.1-3.5]) and using LSD (aOR = 5.44 [CI 95:1.32-30.29]). Underestimation of HIV risk in YMSM is associated with standard HIV risk behavior and modulated by psychosocial aspects. Thus, prevention campaigns aimed at YMSM should include these factors, even though clinical practice does not. Health professionals should reconsider adapting their instruments to measure the risk of HIV in YMSM. It is unknown what score should be used for targeting high-risk YMSM, so more research is needed to fill this gap. Further research is needed to assess what score should be used for targeting high-risk in YMSM.

“Whatever is in the ARVs, is Also in the PrEP” Challenges Associated With Oral Pre-exposure Prophylaxis Use Among Female Sex Workers in South Africa

Background

The national policy on oral pre-exposure prophylaxis (PrEP) for female sex workers (FSWs) was instituted in South Africa in 2016. FSWs were targeted for PrEP due to a Human immunodeficiency virus (HIV) prevalence of 57.7%, which is higher than the prevalence of 19.07% among the general population. Research from demonstration studies has shown that uptake of PrEP has been slower than anticipated, and the purpose of this study was to explore barriers to the uptake of PrEP among FSWs.

Methods

An in-depth qualitative study was conducted with 39 participants, 30 individual participants, and nine focus group participants. Eleven participants consisted of peer educators and two health workers from a sex work and PrEP distribution organization, the rest of the participants (1) were FSWs.

Results

The majority of participants mentioned that little distinction was made between PrEP and antiretrovirals (ARVs) taken by FSWs living with HIV. PrEP was not distributed through public health care facilities, and health workers unknowingly labeled PrEP as ARVs. Consequently, health workers seen as experts created suspicion and contributed to the mistrust of PrEP among FSWs due to mixed messages, and equating PrEP to ARVs reduced uptake. Furthermore, failure to make a clear distinction between oral PrEP and ARVs resulted in accusations of lying, denialism, and deception leveled at users of PrEP by FSWs using ARVs, and sometimes by clients and intimate partners. FSWs using PrEP reported feeling stigmatized and thrust into interpersonal conflict with their peers after choosing PrEP, leading to broken relationships, and some resorting to taking PrEP privately or discontinuing PrEP altogether.

Conclusion

Pre-exposure prophylaxis as an ARV targeted for the prevention of HIV among high-risk groups was found to be stigmatizing. The distinctive use of PrEP and ARVs should be correctly explained to users to minimize confusion, enable differentiation and reduce interpersonal conflict. Cohesion among sex work organizations and public health care facilities is needed to disseminate the correct knowledge on PrEP. A non-stigmatizing approach to the distribution of PrEP may serve to increase uptake and adherence.

The Rhythm of Risk: Sexual Behaviour, PrEP Use and HIV Risk Perception Between 1999 and 2018 Among Men Who Have Sex with Men in Amsterdam, The Netherlands

HIV risk perception plays a crucial role in the uptake of preventive strategies. We investigated how risk perception and its determinants changed between 1999 and 2018 in an open, prospective cohort of 1323 HIV-negative men who have sex with men (MSM). Risk perception, defined as the perceived likelihood of acquiring HIV in the past 6 months, changed over time: being relatively lower in 2008–2011, higher in 2012–2016, and again lower in 2017–2018. Irrespective of calendar year, condomless anal intercourse (AI) with casual partners and high numbers of partners were associated with higher risk perception. In 2017–2018, condomless receptive AI with a partner living with HIV was no longer associated with risk perception, while PrEP use and condomless AI with a steady partner were associated with lower risk perception. We showed that risk perception has fluctuated among MSM in the past 20 years. The Undetectable equals Untransmittable statement and PrEP coincided with lower perceived risk.

Accuracy of HIV Risk Perception in East Zimbabwe 2003-2013

Risk perception for HIV infection is an important determinant for engaging in HIV prevention behaviour. We investigate the degree to which HIV risk perception is accurate, i.e. corresponds to actual HIV infection risks, in a general-population open-cohort study in Zimbabwe (2003-2013) including 7201 individuals over 31,326 person-years. Risk perception for future infection (no/yes) at the beginning of periods between two surveys was associated with increased risk of HIV infection (Cox regression hazard ratio = 1.38 [1.07-1.79], adjusting for socio-demographic characteristics, sexual behaviour, and partner behaviour). The association was stronger among older people (25+ years). This suggests that HIV risk perception can be accurate but the higher HIV incidence (1.27 per 100 person-years) illustrates that individuals may face barriers to HIV prevention behaviour even when they perceive their risks. Gaps in risk perception are underlined by the high incidence among those not perceiving a risk (0.96%), low risk perception even among those reporting potentially risky sexual behaviour, and, particularly, lack of accuracy of risk perception among young people. Innovative interventions are needed to improve accuracy of risk perception but barriers to HIV prevention behaviours need to be addressed too, which may relate to the partner, community, or structural factors.

"I am still negative": Female sex workers' perspectives on uptake and use of daily pre-exposure prophylaxis for HIV prevention in South Africa

Women remain highly vulnerable to HIV infection in sub-Saharan Africa, with female sex workers (FSWs) facing some of the highest rates of HIV. Oral pre-exposure prophylaxis (PrEP) has the potential to reduce new infections among populations at highest risk and end-user perspectives of actual use in ‘real-world’ settings are critical to informing PrEP implementation. This paper presents findings from serial in-depth interviews (IDIs) conducted with FSW participants during the course of the Treatment And Prevention for Sex workers (TAPS) Demonstration Project in South Africa, exploring the lived experiences and perceptions of taking up and using PrEP. This research provides insight into risks and responsibilities facing FSWs perceived as prominent drivers in taking up and using PrEP, how PrEP was adopted to mitigate risk or ameliorate realities, and the characteristics of PrEP most valued, all of which are critical to consider in scale-up. Overall, distrust in the existence and/or efficacy of PrEP affected the motivation of women to come to the clinic and to maintain use. As one of the first reports of PrEP use among FSWs outside of a clinical trial setting, this research shows that it will be important to ensure accurate, relevant, and widespread messaging in communities to generate demand and support for PrEP.

Reasons for Accepting and Declining Free HIV Testing and Counseling Among Young African American Women Living in Disadvantaged Southern Urban Communities

Advancing HIV prevention and treatment among at-risk Southern communities of color requires understanding why voluntary HIV testing is accepted or declined. Reasons for testing decisions were investigated among young African American women (n = 223, mean age = 20.4 years) recruited from disadvantaged areas in a Southern US city. A free HIV test was offered following field interviews that assessed HIV risk behaviors and personal and social network characteristics; 69.1% accepted testing, and all were seronegative. After their decision, participants rated reasons for their choice, which were factor analyzed. A four-factor solution showed that test acceptance was related to (1) current sexual relationships and HIV risk concerns, (2) knowledge of HIV medical treatment benefits, (3) awareness of persons living with HIV, and (4) health protection and HIV test convenience. A three-factor solution showed that test refusal was related to (1) negative consequences of a positive test and privacy concerns, (2) low perception of HIV risk, and (3) anticipated social rejection if the test was positive. Comparisons of factor-based average item scores showed that health protection/HIV test convenience was rated as most influential in test acceptance decisions, whereas low perception of HIV risks was rated as most influential in test rejection decisions. The findings suggest that test acceptance can be promoted by offering free, convenient HIV testing as a health check in a testing context that assesses and provides feedback about participants' HIV risk levels.

Self-reported HIV-positive status but subsequent HIV-negative test result using rapid diagnostic testing algorithms among seven sub-Saharan African military populations

HIV rapid diagnostic tests (RDTs) combined in an algorithm are the current standard for HIV diagnosis in many sub-Saharan African countries, and extensive laboratory testing has confirmed HIV RDTs have excellent sensitivity and specificity. However, false-positive RDT algorithm results have been reported due to a variety of factors, such as suboptimal quality assurance procedures and inaccurate interpretation of results. We conducted HIV serosurveys in seven sub-Saharan African military populations and recorded the frequency of personnel self-reporting HIV positivity, but subsequently testing HIV-negative during the serosurvey. The frequency of individuals who reported they were HIV-positive but subsequently tested HIV-negative using RDT algorithms ranged from 3.3 to 91.1%, suggesting significant rates of prior false-positive HIV RDT algorithm results, which should be confirmed using biological testing across time in future studies. Simple measures could substantially reduce false-positive results, such as greater adherence to quality assurance guidelines and prevalence-specific HIV testing algorithms as described in the World Health Organization’s HIV testing guidelines. Other measures to improve RDT algorithm specificity include classifying individuals with weakly positive test lines as HIV indeterminate and retesting. While expansion of HIV testing in resource-limited countries is critical to identifying HIV-infected individuals for appropriate care and treatment, careful attention to potential causes of false HIV-positive results are needed to prevent the significant medical, psychological, and fiscal costs resulting from individuals receiving a false-positive HIV diagnosis.
