Perceived Candidacy for Pre-exposure Prophylaxis (PrEP) Among Men Who Have Sex with Men in Paris, France

Associations of HIV pre-exposure prophylaxis (PrEP) indication, HIV risk perception and unwillingness to use PrEP among people who inject drugs in Baltimore, MD

Background

Perceived HIV risk may impact willingness to initiate PrEP among people who inject drugs (PWID).

Methods

We analyzed baseline data from PrEP eligible PWID in Baltimore, MD. Risk perception was assessed by PWID relative to the average risk of their age group categorized as: higher-than, lower-than, or about average. Participants were informed of PrEP for HIV prevention and asked about their willingness to use daily PrEP. Associations of PrEP indication (categorized as injection risk only vs any sexual risk), perceived HIV risk and non-willingness to use PrEP was assessed using generalized linear models.

Results

Among 489 participants, 61 % were male, 66 % were Black and mean age was 46 years. One-third (35 %) of the participants were aware of PrEP and <1 % had used PrEP in the prior 30 days. Overall, 30 % of PWID reported lower-than-average perceived HIV risk and 18 % reported non-willingness to use PrEP. Participants with injection risk only were more likely (aOR: 2.75; 95 %CI: 1.60 - 4.73) to report having lower-than-average perceived HIV risk compared to those with any sexual risk. Participants with lower-than-average perceived risk were more likely to report non-willingness to use PrEP compared to those with higher perceived risk (adjusted PR: 1.91; 95 %CI: 1.18 - 3.10).

Conclusion

A considerable proportion of PWID eligible for PrEP reported having low risk of HIV acquisition despite being eligible for PrEP. Consistent and tailored PrEP messaging that addresses drug use HIV risk perception may be critical to increasing PrEP uptake among PWID.

HIV Risk Perception, Willingness to Use PrEP, and PrEP Uptake Among Young Men who have Sex with Men in Washington, DC

Low HIV risk perception is a barrier to PrEP uptake, but few studies have examined risk perception and PrEP uptake among young men who have sex with men (YMSM). We performed a secondary analysis of data collected in 2016 from YMSM ages 16-25 in the Washington, DC metropolitan area who participated in a cross-sectional online survey that aimed to identify strategies for engaging YMSM in PrEP services. Of 188 participants, 115 (61%) were considered eligible for PrEP. Among PrEP-eligible participants who had never used PrEP, 53%, 71%, and 100% with low, moderate, and high risk perception, respectively, were willing to use PrEP (Fisher's exact test p = 0.01). Odds of PrEP willingness were greater among those with moderate/high versus low risk perception (adjusted odds ratio [OR] = 5.62, 95% CI = 1.73-18.34). HIV risk perception was not significantly associated with self-reported PrEP use. These findings suggest the importance of risk perception as a correlate of willingness to use PrEP, which is a key step in existing frameworks of PrEP uptake.

Missed opportunities for HIV pre-exposure prophylaxis among people with recent HIV infection: The French ANRS 95041 OMaPrEP study

OBJECTIVES

Our objective was to identify missed opportunities for the use of pre-exposure prophylaxis (PrEP) in people with recently acquired HIV, factors associated with PrEP knowledge, and reasons for not using PrEP.

DESIGN

This was a French national cross-sectional multicentre study enrolling people diagnosed with recent HIV (incomplete Western blot or negative HIV test in the previous 6 months) in 28 HIV clinical centres. Data were gathered using a self-administered questionnaire (SAQ).

METHOD

We analysed missed opportunities for PrEP use via a retrospective prep cascade. Factors associated with prior knowledge of PrEP and reasons for PrEP non-use among those who knew about PrEP were described using univariate and multivariate logistic regression models.

RESULTS

Of the 224 eligible patients, 185 completed the SAQ and 168 (91%) were eligible for PrEP. Of these, 90% reported seeing at least one physician during the previous year, 26% received information about PrEP, and 5% used PrEP. Factors independently associated with a higher probability of knowing about PrEP were being a man who has sex with men, being aged 25-30 years (vs older), undergoing HIV screening at least once every semester (vs less often; odds ratio [OR] 4.11; 95% confidence interval [CI] 2.00-8.45), and practicing chemsex (OR 3.19; 95% CI 1.12-9.10). Fear of side effects and a low perceived risk of HIV infection were the two most common reasons for not using PrEP (N = 40 [33.33%] and N = 34 [28.3%], respectively).

CONCLUSIONS

We found two gaps in the retrospective PrEP cascade: insufficient provision of PrEP information by healthcare providers (mainly general practitioners) and low PrEP acceptability by informed, eligible patients. More diverse healthcare providers need to be involved in PrEP prescription, and at-risk people need to be sensitized to the risk of HIV infection.

Acceptability of and Preferences for Long-Acting Injectable HIV PrEP and Other PrEP Modalities among Sexual Minority Men in Nigeria, Africa

Sexual minority men (SMM) in Nigeria have been disproportionately affected by HIV. Pre-exposure prophylaxis (PrEP) reduces risk for HIV acquisition among SMM by over 90%. The current study investigated the association between demographics, socioeconomic marginalization, sexual health and willingness to use long-acting injectable (LAI-) PrEP and preferences for other PrEP modalities in a sample of HIV-negative SMM in Nigeria. Between March and June 2019, SMM residing in Abuja, Delta, Lagos, and Plateau completed a quantitative survey. To examine willingness to use LAI-PrEP and PrEP modality preferences, multivariable binomial and multinomial logistic regression models were fit. We found that 88% were willing to use LAI-PrEP and 44% preferred LAI-PrEP to other PrEP modalities. Participants who reported interest in LAI-PrEP were more likely to be single, engage in inconsistent condom use, and report having a primary care provider. Compared to participants who preferred daily oral PrEP, participants who preferred other PrEP modalities had higher odds of having some university education/university degree or higher and reporting low financial hardship. It is imperative that SMM in Nigeria are prioritized for access to new HIV prevention interventions, as they bear a disproportionate burden of HIV and are especially vulnerable to HIV infection.

Behavioral and social science research to support accelerated and equitable implementation of long-acting preexposure prophylaxis

PURPOSE OF REVIEW

The sociobehavioral research agenda for HIV prevention urgently needs to progress beyond research on end user preferences to examine how to best support patient access, engagement, and choice in the rollout of long-acting modalities. We outline critical challenges for an era of choice in biomedical prevention that could benefit from the rigorous application of sociobehavioral research methods.

RECENT FINDINGS

Research in three areas could accelerate implementation of long-acting antiretrovirals for prevention: integrating dual process models into research on patient decision-making and behavior; identifying strategies that mitigate against unconscious and implicit biases in provider decision-making and behavior; and developing tools to support patient-centered communication that incorporate research in both of the first two areas.

SUMMARY

We encourage the development of dual process models and measures to better understand patient behavior, including behavior related to initiating biomedical prevention, choice of prevention strategy, switching among strategies, and discontinuation. Second, there is the need to develop intervention research that targets provider behavior. Finally, we call for research to inform patient-centered communication tools that integrate an understanding of affective drivers of preexposure prophylaxis (PrEP) decision-making and protect against implicit bias in provider recommendations related to PrEP.

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.

PrEP eligibility, HIV risk perception, and willingness to use PrEP among high-risk men who have sex with men in India: A cross-sectional survey

HIV pre-exposure prophylaxis (PrEP) is not yet included in India's national AIDS program, with demonstration projects for MSM in planning stages. In order to support PrEP roll-out for MSM, we assessed: (1) associations between guideline-informed PrEP eligibility, HIV risk perception, and perceived PrEP benefits and costs, with willingness to use PrEP (WTUP); and (2) correlates of non-WTUP among PrEP-eligible MSM. Data were collected from MSM (n = 197) sampled from cruising sites in Mumbai and Chennai. More than half (58.4%) reported inconsistent condom use with male partners, 88.3% >1 male partner, and 48.6% engaging in sex work (all past month). Overall, 76.6% reported they would "definitely use" PrEP. Among 92.9% deemed PrEP-eligible, 79.2% reported WTUP. In adjusted analyses, PrEP eligibility (aOR = 5.31, 95% CI 1.11, 25.45), medium (aOR = 2.41, 95% CI 1.03, 5.63) or high (aOR = 13.08, 95% CI 1.29, 132.27) perceived HIV risk, and greater perceived benefits (aOR = 1.13, 95% CI 1.03, 1.24) were associated with higher odds of WTUP. Among PrEP-eligible MSM, non-WTUP was associated with low HIV risk perception and lower perceived benefits. Facilitating accurate risk assessment and promoting awareness of PrEP benefits and eligibility criteria may increase PrEP uptake among MSM in India.

Are Sexual Minority Stressors Associated with Young Men who Have Sex with Men's (YMSM) Level of Engagement in PrEP?

Sexual minority stressors (community homophobia, sexuality-related discrimination, and internalized homonegativity) are negatively associated with accessing HIV prevention services among men who have sex with men (MSM). Few studies have tested minority stressors' associations with PrEP engagement among high-HIV risk young MSM (YMSM). Therefore, we assessed the associations between PrEP-indicated YMSM's progression along the PrEP continuum and their experiences of minority stress. N = 229 YMSM completed a web-survey on PrEP-related behaviors and minority stress. Adjusted for covariates, we developed two partial-proportional odds models examining the associations between PrEP continuum progression and minority stressors, as a composite, and community homophobia, sexuality-related discrimination, and internalized homonegativity, respectively. Our multivariable model demonstrated minority stress levels to be negatively associated with PrEP continuum location (AOR = 0.76, 95% CI: 0.58-0.99). Broken down, discrimination was positively associated with reporting being at an advanced location along the continuum (AOR = 1.39, 95% CI: 1.06-1.82). Internalized homonegativity was negatively associated with continuum location between PrEP-aware participants with no intention to initiate and participants who intended to initiate PrEP (AOR = 0.45, 95% CI: 0.27-0.77) and between those who intended to initiate and those who had ever used PrEP (AOR = 0.39, 95% CI: 0.22-0.69). Our findings suggest that minority stress, especially internalized homonegativity, remains a barrier to PrEP among PrEP-indicated YMSM. Sexuality-related discrimination was associated with PrEP continuum progression, suggesting potentially well-developed, adaptive coping skills (e.g., ability to locate sexuality-affirming providers). Coupled with stigma reduction efforts, HIV prevention services aiming to promote PrEP should incorporate internalized homonegativity screenings and referrals into sexuality-affirming resources for PrEP-indicated YMSM.

Risk Behavior Not Associated with Self-Perception of PrEP Candidacy: Implications for Designing PrEP Services

In a study of sexually-active HIV-negative men who have sex with men (MSM) in China, we compared behavioral indication for pre-exposure prophylaxis (PrEP) based on risk criteria to self-perception of PrEP candidacy (SPC) and explored factors associated with SPC. Of 708 MSM surveyed, 323 (45.6%) were behaviorally-indicated for PrEP, among whom 42.1% self-perceived as appropriate PrEP candidates. In a multivariable model we found no association between sexual behavior nor HIV risk perception and SPC but found that higher perceived benefits of PrEP, increased frequency of HIV testing, and low condom use self-efficacy were positively-associated with SPC. In a sub-analysis restricted to MSM behaviorally-indicated for PrEP, relationship-factors were also significant. Our findings suggest that PrEP implementers should look beyond risk criteria to consider shared decision-making tools that support individuals to assess whether they are appropriate PrEP candidates based on their existing HIV prevention strategies, sexual health goals, and relationship dynamics.
