Factors associated with perceived accuracy of the Undetectable = Untransmittable slogan among men who have sex with men: Implications for messaging scale-up and implementation

Awareness of U = U among Sexual and Gender Minorities in Brazil, Mexico, and Peru: Differences According to Self-reported HIV Status

The slogan Undetectable equals Untransmittable (U = U) communicates that people living with HIV (PLHIV) who are on antiretroviral therapy (ART) will not transmit HIV to their sexual partners. We describe awareness of U = U among sexual and gender minorities (SGM) living in Brazil, Mexico, and Peru by self-reported HIV status (PLHIV, negative, unknown) during 2021 using an online survey. We estimated two models using Poisson regression for each population group: Model A including socio-demographic factors (country, gender, age, race, education, and income), and then Model B including taking ART (for PLHIV) or risk behavior, ever-taking PrEP, and HIV risk perception (for HIV-negative or of unknown HIV status). A total of 21,590 respondents were included (Brazil: 61%, Mexico: 30%, Peru: 9%). Among HIV-negative (74%) and unknown status (12%), 13% ever used PrEP. Among PLHIV (13%), 93% reported current use of ART. Awareness of U = U was 89% in both Brazil and Mexico, which was higher than in Peru 64%. Awareness of U = U was higher among PLHIV (96%) than HIV-negative (88%) and HIV-unknown (70%). In multivariate models, PLHIV with lower education were less aware of U = U, while those taking ART were more aware. Among HIV-negative, non-cisgender, lower income, and those with lower education had lower awareness of U = U, while individuals ever using PrEP had higher awareness. In conclusion, awareness of U = U varied by HIV status, socio-demographic characteristics, and HIV risk behavior. The concept of U = U should be disseminated through educational strategies and include a focus on SGM to combat HIV stigma.

The Potential Role of Undetectable = Untransmittable (U = U) in Reducing HIV Stigma among Sexual Minority Men in the US

The Undetectable = Untransmittable (U = U) message and its scientific underpinnings have been widely suggested to reduce HIV stigma. However, misunderstanding and skepticism about U = U may prevent this destigmatizing potential from being fully realized. This cross-sectional study examined associations between U = U belief (belief that someone with a sustained undetectable viral load has zero risk of sexually transmitting HIV) and HIV stigma among US sexual minority men. Differences by serostatus and effects of brief informational messaging were also explored. The survey was completed online by 106 men living with HIV and 351 HIV-negative/status-unknown men (2019-2020). Participants were 18-83 years old (M[SD] = 41[13.0]). Most were non-Hispanic White (70.0%) and gay (82.9%). Although nearly all participants (95.6%) were aware of U = U, only 41.1% believed U = U. A greater percentage of participants living with HIV (66.0%) believed U = U compared with HIV-negative/status-unknown participants (33.6%). Among participants living with HIV, U = U belief was not significantly associated with perceived, internalized, or experienced HIV stigma or with viral load prejudice (prejudice against people who have a detectable HIV viral load). Among HIV-negative/status-unknown participants, U = U belief was associated with less frequently enacted HIV discrimination, more positive feelings toward people with an undetectable viral load, and lower personal endorsement of stigmatizing beliefs. Brief informational messaging about U = U did not affect most stigma dimensions and did not favorably affect any. Interventions are needed to correct commonly held, outdated misconceptions about HIV transmission risk. Such initiatives must not only engage people living with HIV but also engage HIV-negative/status-unknown people to maximize the destigmatizing potential of U = U.

A psychosocial network approach studying biomedical HIV prevention uptake between 2017 and 2019

Biomedical HIV-prevention strategies (BmPS) among men who have sex with men (MSM), such as pre-exposure prophylaxis (PrEP) and viral load sorting (VLS), are essential but relatively new and their uptake gradual. Using an extension of the causal attitude network approach, we investigated which beliefs are related to uptake of PrEP and VLS at each time-point. We included 632 HIV-negative MSM from the Amsterdam Cohort Studies from four data-waves between 2017 and 2019. We estimated weighted, undirected networks for each time-point, where we included pairwise interactions of PrEP and VLS uptake and related beliefs. PrEP use increased from 10 to 31% (p < 0.001), while VLS was reported by 7-10% at each time-point. Uptake of both BmPS was directly related to the perceived positive impact of the strategy on one's quality of sex life and perceived supportive social norms. Overall network structure differed between time points, specifically in regard to PrEP. At earlier time points, perceptions of efficacy and affordability played an important role for PrEP uptake, while more recently social and health-related concerns became increasingly important.The network structure differed across data-waves, suggesting specific time changes in uptake motives. These findings may be used in communication to increase prevention uptake.

Attitudes and Beliefs About HIV Treatment as Prevention Among People Who are Not Engaged in HIV Care, 2018-2019

Treatment as prevention (TasP) is an effective HIV prevention strategy. Our objectives were to explore TasP attitudes and beliefs among people with HIV (PWH) who are not engaged in care and to examine attitudes and beliefs by selected characteristics. We sampled PWH who had participated in the Medical Monitoring Project (MMP), a structured interview survey, from June 2018-May 2019 to participate in 60-minute semi-structured telephone interviews. We obtained sociodemographic and behavioral quantitative data from the MMP structured interview. We used applied thematic analysis to analyze the qualitative data and integrated the qualitative and quantitative data during analysis. Negative attitudes and beliefs, especially skepticism and mistrust, about TasP were pervasive. Only one participant who identified as female, was not sexually active, and had not heard of TasP held positive attitudes and beliefs about TasP. TasP messages should use clear and unambiguous language, address mistrust, and reach people who are not engaged in medical care.

Binge Drinking Moderates Unprotected Sex Among HIV Sero-Similar Same Sex Male Couples: An Actor-Partner Interdependence Model

Most new HIV diagnoses in the US occur among sexual minority men (SMM). The majority (69%) of new HIV diagnoses among US SMM are due to transmission from main sex partners. We identified multilevel correlates of unprotected anal intercourse (UAI; condomless anal intercourse while not using a biomedical strategy) among SMM couples using the Actor Partner Interdependence Model (APIM). Participants were US SMM over 18 years, with a primary male partner > 6 months. Couples were recruited online from April 2016 until June 2017 and interviewed using self-administered computer-assisted surveys. We used a series of APIM regressions to assess multilevel associations with UAI. We also tested the moderating role of an individual's binge drinking on the relationship between HIV status similarity and UAI. Among 798 participants (n = 411 couples), 61% reported UAI in the past 6 months. Binge drinking (52%) and physical intimate partner violence (IPV; 34%) were considerably high within our sample. Actor's binge drinking, reporting experiencing and/or perpetrating physical IPV, and partner's trust were positively associated with UAI. Actor having other sexual partner(s), using illegal drugs (not marijuana), and length of relationship were negatively associated with UAI. Binge drinking positively moderated UAI among HIV serostatus similar partners. HIV prevention programming should integrate components on IPV and binge drinking reduction- especially among HIV serostatus similar couples.

Barriers to Treatment as Prevention Adoption Among Sexual and Gender Minority Individuals Who Have Sex with Men in the United States

The discovery that people with an undetectable HIV viral load are unable to transmit the virus to sex partners (U = U) has ushered in a new era in HIV care. As a result of this discovery, treatment as prevention (TasP) has become a powerful tool toward ending the epidemic. However, despite its sound scientific basis, many communities affected by HIV face barriers toward adopting TasP as a complete HIV prevention strategy. In addition, most research to date has only focused on TasP in the context of committed monogamous partnerships. To identify barriers to TasP adoption among some of those most affected by HIV, we conducted in-depth qualitative interviews with 62 sexual and gender minority individuals of varying serostatuses. Participants were identified from the results of an online survey, where those who indicated at least some awareness of TasP were invited to partake in a follow-up interview. Interviews were thematically coded to identify emergent themes relating to TasP adoption. Seven primary barriers emerged from data analysis pertaining to TasP science, internalized beliefs about HIV safety, and interactional dynamics between partners: (1) unfamiliarity with TasP science, (2) perceived limitations of TasP science, (3) difficulty changing understanding of "safe sex," (4) unwillingness to rely on partners' reports of being undetectable, (5) persistent HIV stigma, (6) less difficulty finding serosimilar partners, and (7) difficulty incorporating TasP into casual encounters. Together, these barriers confirm the existing findings about TasP adoption, and extend the literature by identifying barriers beyond a lack of education and outside of monogamous contexts.

Psychosocial factors involved in the very rare use of HIV testing among French MSM: a cross-sectional study

BACKGROUND

Among men who have sex with men (MSM) in France, the average time between infection and testing is too long, leading to late diagnosis. A better understanding of very infrequent HIV testing (VIT; i.e. have not tested for at least 6 years) could help reach unknowingly long-infected MSM. Thus, we aim to identify psychosocial factors associated with VIT among MSM in France.

METHODS

We conducted a multivariate regression on the data collected via a cross-sectional survey among 315 MSM.

RESULTS

11.1% (n = 35) had VIT. Being over 50, not knowing about the existence of HIV self-testing, having predominantly heterosexual friends, and the level of belief in the effectiveness of treatment as prevention were significantly associated with VIT.

CONCLUSION

We call for the development, at the same time, of programs that operate at the individual, institutional and societal levels. In particular, we recommend diversifying the modes of promotion and access to prevention tools, especially for MSM over 50 years old or with little or no connection to the gay community.

Leaving No One Behind: Human Rights and Gender as Critical Frameworks for U=U

Experience has shown the need to explicitly address human rights and gender-related barriers in the rollout of HIV-related biomedical innovations, including "undetectable equals untransmittable" (U=U). This paper brings to light rights and gender considerations relevant to supporting U=U, recognizing a range of barriers that remain to be addressed for all people to benefit equally from U=U. We conducted a literature review to ascertain how human rights and gender were addressed in relevant publications, including peer-reviewed articles published between 2006 and 2020, relevant nongovernmental and global organizations' publications, and abstracts presented at the 2019 International AIDS Conference, that explicitly addressed U=U or "treatment as prevention." Despite evidence to illustrate the importance of attention to human rights and gender within U=U policies and interventions, there remains a lack of explicit attention to human rights and gender considerations in research and programming, particularly with regard to the rights principles of participation and accountability. Explicitly engaging all of these dimensions is key to informing interventions and improving people's lives, health, and well-being.

Sexual Mixing by HIV Status and Pre-exposure Prophylaxis Use Among Men Who Have Sex With Men: Addressing Information Bias

BACKGROUND

Population-level estimates of sexual network mixing for parameterizing prediction models of pre-exposure prophylaxis (PrEP) effectiveness are needed to inform prevention of HIV transmission among men who have sex with men (MSM). Estimates obtained by egocentric sampling are vulnerable to information bias due to incomplete respondent knowledge.

METHODS

We estimated patterns of serosorting and PrEP sorting among MSM in the United States using data from a 2017-2019 egocentric sexual network study. Respondents served as proxies to report the HIV status and PrEP use of recent sexual partners. We contrasted results from a complete-case analysis (unknown HIV and PrEP excluded) versus a bias analysis with respondent-reported data stochastically reclassified to simulate unobserved self-reported data from sexual partners.

RESULTS

We found strong evidence of preferential partnering across analytical approaches. The bias analysis showed concordance between sexual partners of HIV diagnosis and PrEP use statuses for MSM with diagnosed HIV (39%; 95% simulation interval: 31, 46), MSM who used PrEP (32%; 21, 37), and MSM who did not use PrEP (83%; 79, 87). The fraction of partners with diagnosed HIV was higher among MSM who used PrEP (11%; 9, 14) compared with MSM who did not use PrEP (4%; 3, 5). Comparatively, across all strata of respondents, the complete-case analysis overestimated the fractions of partners with diagnosed HIV or PrEP use.

CONCLUSIONS

We found evidence consistent with HIV and PrEP sorting among MSM, which may decrease the population-level effectiveness of PrEP. Bias analyses can improve mixing estimates for parameterization of transmission models.

HIV knowledge and its correlation with the Undetectable = Untransmittable slogan in Brazil

Knowledge about HIV transmission and prevention is a necessary step for adopting preventive behaviors. We assessed HIV knowledge and its correlation with the perceived accuracy of the "Undetectable = Untransmittable" (U=U) slogan in an online sample with 401 adult Brazilians. Overall, 28% of participants showed high HIV knowledge level. The perceived accuracy of the U=U slogan significantly correlated with HIV knowledge. Younger participants, those reporting lower income or lower education, or who had never tested for HIV showed poorer HIV knowledge. Filling gaps of knowledge among specific populations is urgent in order to increase preventive behaviors and decrease HIV stigma.

LGBTQ+ Affirming Care May Increase Awareness and Understanding of Undetectable = Untransmittable among Midlife and Older Gay and Bisexual Men in the US South

One of the most significant innovations in HIV prevention is the use of HIV treatment to prevent HIV transmission. This information has been disseminated as the "Undetectable = Untransmittable" (U = U) message. Despite evidence of effectiveness, U = U awareness, belief, and understanding remains limited in some communities. In this study, we examine whether having an LGBTQ affirming healthcare provider increases U = U awareness, belief, and understanding among midlife and older gay and bisexual men in the US south, an understudied and underserved population and region where new HIV infections are increasing. We used data from the Vanderbilt University Social Networks Aging and Policy Study (VUSNAPS) on sexual minority men aged 50 to 76 from four southern US states collected in 2020-2021. We found that only one in four men reported prior awareness of U = U, but awareness was higher among men who have an LGBTQ affirming provider. Among HIV negative men, those with an affirming provider were more likely to believe and understand U = U, have more accurate risk perception, and have ever tested for HIV. Improving access to LGBTQ affirming healthcare may improve U = U awareness, belief, and understanding, which could help to curb HIV transmission in the US south.

Awareness and perception of accuracy of the Undetectable=Untransmittable message (U=U) in Italy: results from a survey among PLWHA, infectious-diseases physicians and people having unprotected sex

Evidences on the absence of risk of sexual transmission of HIV by persons living with HIV/AIDS (PLWHA) with undetectable plasma HIV-RNA (HIV-RNA <200 copies/ml) led to the worldwide campaign "U = U" (undetectable = untransmittable). The purpose of this study was to evaluate the perceived accuracy of this message among PLWHA, HIV-negative people having unprotected sex (PHUS) and infectious diseases' (ID) physicians in Italy. A nationwide survey has been conducted using three different anonymous questionnaires (for ID physicians, PLWHA and PHUS). A total of 1121 participants filled the questionnaires: 397 PLWHA; 90 physicians; 634 PHUS. Awareness of U = U message has been reported in 74%, 92% and 47% of PLWHA, ID physicians and PHUS, respectively. The perception of accuracy of the U = U message among those aware was reported as high in 80.4%, 79.5% and 67.3% of PLWHA, ID physicians and PHUS, respectively. Physicians perceived that 11% of PLWHA have a high rate of perception of U = U, whereas among PLWHA, only 34% reported definitive positive messages from physicians. Discrepancies between awareness and perception of accuracy of the message U = U in PLWHA and physicians have been found, suggesting still low confidence in the community regarding the message itself.

Using social and sexual networking mobile applications to promote HIV testing, medical care and prevention services among Latino men who have sex with men in Los Angeles County, California, USA

HIV disproportionately affects Latinos versus Whites, with Latinos having higher rates of HIV. Additionally, many HIV-positive Latinos are unaware of their infection. Proyecto Protégete, an HIV prevention intervention developed for Latino men who have sex with men (MSM), used social and sexual networking mobile applications (apps) to recruit individuals for HIV testing and linkage to medical care and prevention services. This study occurred in Los Angeles County, California, USA from December 18, 2015 to April 22, 2017. The study’s primary aim was to assess Proyecto Protégete‘s ability to successfully recruit Latino MSM involved in high-risk sexual activities. A secondary aim was to evaluate its capacity to promote HIV testing and linkage to HIV medical care and prevention services among this population by comparing it to two programs with similar samples. Comparisons using Fisher’s Exact Test were conducted between Proyecto Protégete and the HIV testing program of the agency in which Proyecto Protégete was located and the County-funded HIV testing programs to compare the samples’ rates of HIV-positive Latino MSM identified through HIV testing and linked to HIV medical care and prevention services. Participants were recruited through seven apps. In Proyecto Protégete, 9,573 individuals completed the screener, 4,657 were eligible, and 359 (7.7% of those eligible) enrolled. Among those enrolled, 79% reported anal sex without a condom in the previous twelve months; 51% reported anal sex under the influence of alcohol. The HIV positivity rates were as follows: Proyecto Protégete, 1.71%; the agency, 1.25% (p = .293, compared to Proyecto Protégete); and the County, 1.09% (p = .172, compared to Proyecto Protégete). The rates of those confirmed as new HIV-positives and linked to medical care within 30 days were as follows: Proyecto Protégete, 71.4%; the agency, 81.5% (p = .450, compared to Proyecto Protégete); and the County, 77.3% (p = .503, compared to Proyecto Protégete). Proyecto Protégete had a higher rate of linked referrals to prevention services than the agency’s testing program (19.5% versus 8.3%, p < .001). Proyecto Protégete experienced successes in some areas but not in others. Future research should build on Proyecto Protégete’s experiences to promote HIV-related services among Latino MSM.

Awareness, knowledge, and attitudes related to HIV pre-exposure prophylaxis and other prevention strategies among physicians from Brazil and Mexico: cross-sectional web-based survey

Background

In order to end the HIV epidemic by 2030, combination HIV prevention including pre-exposure prophylaxis (PrEP) should be widely available, especially for the most vulnerable populations. In Latin America and the Caribbean (LAC), only 14 out of 46 countries have access to PrEP. In Brazil and Mexico, PrEP has been provided at no cost through the Public Health System since 2017 and 2021, respectively. Thus, HIV physicians’ perspectives about PrEP and other prevention strategies may differ. This study aimed to compare awareness, knowledge, and attitudes related to PrEP and other prevention strategies among HIV physicians from Brazil and Mexico.

Methods

Cross-sectional, web-based survey targeting physicians who prescribe antiretrovirals from both countries. Participants answered questions on socio-demographic, medical experience, awareness, knowledge, and attitudes towards PrEP and other HIV prevention strategies. We stratified all variables per country and compared frequencies using Chi-square, Fisher exact, and Wilcoxon-Mann-Whitney tests, as appropriate.

Results

From January–October 2020, 481 HIV physicians were included: 339(70.5%) from Brazil, 276(57.4%) male, and median age was 43 years (IQR = 36–53). Awareness of PrEP did not differ between Brazil and Mexico (84.6%), while awareness of other prevention strategies, including post-exposure prophylaxis and new PrEP technologies, was higher in Brazil. More Brazilians perceived U=U as completely accurate compared to Mexicans (74.0% vs. 62.0%, P < .001). Willingness to prescribe PrEP was 74.2%, higher among Brazilians (78.2%, P = .01). Overall, participants had concerns about consistent access to PrEP medication and the risk of antiretroviral resistance in case of acute HIV infection or seroconversion. The main barriers reported were assumptions that users could have low PrEP knowledge (62.0%) or limited capacity for adherence (59.0%). Compared to Brazilians, Mexicans reported more concerns and barriers to PrEP prescription (all; P ≤ .05), except for consistent access to PrEP medication and the lack of professionals to prescribe PrEP (both; P ≤ .01).

Conclusions

Although awareness of PrEP was similar in Brazil and Mexico, differences in knowledge and attitudes may reflect the availability and stage of PrEP implementation in these countries. Strengthening and increasing information on PrEP technologies and other HIV prevention strategies among HIV physicians could improve their comfort to prescribe these strategies and facilitate their scale-up in LAC.

Development and Evaluation of Short-Form Measures of the HIV/AIDS Knowledge Assessment Tool Among Sexual and Gender Minorities in Brazil: Cross-sectional Study

Background

In theoretical models of health behavior, knowledge about disease transmission and self-protective behaviors are conceptualized as important drivers of behavior change. Several studies conducted in Brazil point to an unfortunate convergence of sexual and gender minority (SGM) populations with low levels of HIV knowledge and younger age, lower education, engagement in higher-risk sexual behavior, and never having tested for HIV. Measures to assess level of HIV knowledge have been previously published, including the 12-item HIV/AIDS Knowledge Assessment (HIV-KA) tool. However, measure length can be a barrier to assessment.

Objective

We started from the 12-item HIV-KA tool and developed candidate short forms using statistical procedures, evaluated their psychometric properties, and tested the equivalency of their associations with other measures of HIV knowledge compared to the 12-item version.

Methods

A convenience sample of SGM was recruited during September 2020 to complete an online survey through advertisements on two social networking apps (Grindr and Hornet). The survey instrument included items on sociodemographic information, prior HIV testing and HIV test results, preexposure prophylaxis (PrEP) and antiretroviral treatment use, sexual behavior, and 3 HIV knowledge measures: the HIV-KA, World Health Organization Knowledge About HIV Transmission Prevention Indicator, and the Brief HIV Knowledge Questionnaire. We used exploratory factor analysis and confirmatory factor analysis (CFA) to assess the factor structure of the of the HIV-KA. We used optimal test assembly (OTA) methods to develop candidate short forms of the HIV-KA and evaluated them based on prespecified reliability, concurrent validity, and statistically equivalent convergent validity criteria.

Results

Among 2552 SGM individuals from Brazil, mean age was 35.1 years, 98.2% (2507/2552) cisgender men and 1.8% (45/2552) transgender/nonbinary, 56.5% (1441/2552) White, and 31.0% (792/2552) self-reported HIV positive. CFA indicated a 1-factor structure for the 12-item HIV-KA. Concurrent validity correlations were high for all short forms with 6 items, but only versions with 9 items were as reliable as the full-length form and demonstrated equivalency for convergent validity correlations. Suggesting post hoc convergent validity, HIV knowledge scores using the 9- and 10-item short forms were higher for participants who perceived the Undetectable Equals Untransmittable (U=U) slogan as completely accurate versus not accurate. Suggesting post hoc concurrent validity, participants of younger age, of Black, Pardo or indigenous race, and reporting lower education and lower income scored lower on HIV knowledge. Participants who never tested for HIV scored lower than those who tested negative or positive, while those currently using PrEP scored higher than those reporting past or never use.

Conclusions

OTA methods were used to shorten the 12-item HIV-KA to 9-item and 10-item versions while maintaining comparable reliability and validity among a large sample of Brazilian SGM. However, these short forms did not shorten sufficiently to justify deviation from the full measure.

Durable Viral Suppression Among People with HIV and Problem Substance Use in the Era of Universal Antiretroviral Treatment

This study explored factors associated with durable viral suppression (DVS) among two groups of people living with HIV (PLWH) and problem substance use in the context of universal antiretroviral treatment initiation. Participants (N = 99) were recruited between 2014-2017 from public sexual health clinics [SHC] and a hospital detoxification unit [detox]). DVS (NYC HIV surveillance registry) was defined as two consecutive viral load tests ≤ 200 copies/mL, ≤ 90 days apart, with all other viral loads suppressed over 12 or 18 months. Detox participants were significantly older, with more unstable housing/employment, substance use severity, and longer-term HIV vs. SHC participants. Older age, opioid and stimulant use disorder were significantly associated with lower odds of DVS, while fulltime employment and stable housing were significantly associated with higher odds of DVS at 12-month follow-up. Patterns held at 18-month follow-up. Co-located substance use and HIV services, funding for supportive housing, and collaborative patient-provider relationships could improve DVS among populations with the syndemic of problem substance use, poverty, and long-term HIV.

Changing Knowledge and Attitudes Towards HIV Treatment-as-Prevention and "Undetectable = Untransmittable": A Systematic Review

People on HIV treatment with undetectable virus cannot transmit HIV sexually (Undetectable = Untransmittable, U = U). However, the science of treatment-as-prevention (TasP) may not be widely understood by people with and without HIV who could benefit from this information. We systematically reviewed the global literature on knowledge and attitudes related to TasP and interventions providing TasP or U = U information. We included studies of providers, patients, and communities from all regions of the world, published 2008–2020. We screened 885 papers and abstracts and identified 72 for inclusion. Studies in high-income settings reported high awareness of TasP but gaps in knowledge about the likelihood of transmission with undetectable HIV. Greater knowledge was associated with more positive attitudes towards TasP. Extant literature shows low awareness of TasP in Africa where 2 in 3 people with HIV live. The emerging evidence on interventions delivering information on TasP suggests beneficial impacts on knowledge, stigma, HIV testing, and viral suppression.

Prevalence of U = U Awareness and Its Association with Anticipated HIV Stigma Among Low-Income Heterosexually Active Black and Latino Adults in New York City, 2019

The fact that people with HIV (PWH) who have an undetectable viral load cannot sexually transmit HIV has been disseminated under the messaging "Undetectable = Untransmittable" (U = U). U = U messaging intends to destigmatize HIV by demonstrating that PWH can have healthy sexual lives. Among a sample of low-income heterosexually active Black and Latino adults, we aimed to (1) measure the prevalence of U = U awareness and (2) determine its association with anticipated HIV stigma. Low-income heterosexually active adults were recruited through respondent-driven sampling in New York City. Among Black and Latino participants who self-reported not having HIV, multiple linear regression was used to determine the association between U = U awareness with the following types of anticipated HIV stigma, as determined by principal component analyses: (1) general; (2) dating related; and (3) sex related. Of 485 participants, 35% were aware of U = U. Those who were aware reported less dating-related [adjusted B: -0.20; 95% confidence interval (CI): -0.37 to -0.03] and sex-related (adjusted B: -0.15; 95% CI: -0.29 to -0.002) anticipated HIV stigma. Although the prevalence of U = U awareness was much lower than reported in other populations (e.g., gender and sexual minorities and PWH), prevalence was moderate in our sample, given that awareness efforts have generally not focused on heterosexually active adults. Our findings provide preliminary evidence that U = U awareness may have an impact on anticipated HIV stigma related to dating and sex. Additional methods to disseminate U = U messaging and dismantle HIV stigma in this population should be explored.

Investigating the effect of undetectable = untransmittable message frames on HIV stigma: an online experiment

People living with HIV who maintain an undetectable viral load by adhering to antiretroviral therapy cannot transmit the virus to others. The present pre-registered study sought to investigate whether messages about this fact have the potential to decrease HIV stigma, drawing on the framework of the Elaboration Likelihood Model to test variations in message framing, and measuring issue involvement as a covariate. Participants (N = 314) were randomised to one of three conditions: control message, opinion-based message, and evidence-based message. Using a between-subjects one-way ANOVA, it was found that there was no significant effect of the U = U message on perceived risk or perceived accuracy of the message. When controlling for issue involvement, operationalised as the extent to which participants felt that they can empathise with people living with HIV, participants who received the evidence-based U = U message reported lower stigmatising attitudes than those who received the opinion-based message. These adjusted results suggested that evidence-based framing was more effective than opinion-based framing and an unrelated control message.

Reimaging an AIDS free generation: Examining youth and young adults' personal agency and its association with HIV testing

Exploring youth and young adult's agency may be a way to increase HIV testing and help end the HIV epidemic. We used data from the National Survey of Teens and Young Adults (15-24) on HIV/AIDS (N = 1,437). Data were collected from September 21-October 1, 2012. The sample included 748 girls and 689 boys; and the mean age is 20 years (SD: 3.02). Youth and young adults completed a 40-question survey on attitudes and knowledge about HIV. Using a multivariable logistic regression analysis, study findings suggest that focusing on protective health behaviors like the role youth can play in ending the epidemic and hearing about an AIDS-free generation were both associated with an increase in HIV testing. Our study finds that enhancing the role and influence of personal agency can inform HIV prevention and intervention programs that are specific to youth.

Constructions of HIV Risk Among a Diverse Sample of HIV-Negative Young Men Who Have Sex With Men Who Are Repeat Testers

INTRODUCTION

To end the HIV epidemic, HIV prevention and pre-exposure prophylaxis (PrEP) promotion efforts must reach young men who have sex with men (YMSM) at greatest risk for HIV. This study qualitatively explored whether common metrics used by clinicians, scientists, and public health officials to objectively assess HIV risk align with how YMSM conceptualize their risk for HIV and the factors that shape YMSM's risk perceptions.

METHODS

Interviews with a racially/ethnically diverse sample of HIV-negative YMSM (ages 19-24 years, 60% Latinx; n = 20) examined conceptualizations of HIV risk within the context of repeat HIV testing. Iterative, applied thematic analysis examined how participants conceptualized and constructed their HIV risk, and compared participants' descriptions of their risk with a validated quantitative assessment of HIV risk that reliably predicts HIV seroconversion in this group.

RESULTS

Objective quantitative assessments of HIV risk poorly aligned with participants' perceived HIV risk. Participants described their current risk in relative terms (relative to past risk and relative to friends'/peers' risk) and described age/developmental stage and changes in knowledge about HIV prevention as key factors in risk changes over time. Other factors included substance use and trust/mistrust in sexual partners and scientific advances in HIV prevention (eg, U = U and PrEP). Factors that influenced participants' perceived HIV risk were similar regardless of objective risk assessment.

CONCLUSIONS

Quantitative assessments of risk may poorly align with risk perception among YMSM. Although objective metrics can effectively target YMSM at greatest risk for HIV transmission, interventions to improve prevention behaviors and PrEP uptake may be more effective when tailored to bridge the disconnection between objective HIV risk assessments and YMSM's constructions of risk.

Sexual Behaviors After PrEP Discontinuation Among HIV Serodiscordant Couples in Kenya and Uganda

Supplemental Digital Content is Available in the Text.

A strategy of pre-exposure prophylaxis (PrEP) transitioning to treatment as prevention is highly efficacious and cost effective for prevention of HIV transmission within HIV serodiscordant couples. We assessed whether couples who adopted this strategy experienced changes in sexual behaviors after HIV-negative partners discontinued PrEP and transitioned to rely primarily on their partner's adherence to antiretroviral therapy (ART) for prevention.

Who knows about U = U? Social positionality and knowledge about the (un)transmissibility of HIV from people with undetectable viral loads

"U = U" is the principle that HIV is untransmittable from people living with an undetectable HIV viral-load. Wide-spread knowledge about U = U is believed to produce public health benefit by reducing HIV-related stigma - promoting wellbeing for people living with HIV. Therefore, we examined the diffusion of U = U with respect to the social position of sexual and gender minority men (SGMM). Participants were SGMM recruited from 16 LGBTQ2S+ pride festivals across Canada. Social position was measured using an index assessing whether participants were (a) trans, (b) a person of colour, (c) Indigenous, (d) born abroad, (e) bisexual or straight, (f) not out, (g) struggling with money, (h) not college educated, (i) and not participating in LGBTQ2S+ Organizations, Queer Pop-ups, or HIV advocacy organizations. Multivariable logistic regression tested whether Index Scores were associated with knowledge about U = U. Among 2681 participants, 72.6% knew about U = U. For HIV-negative/unknown status SGMM, each 1-point increase in Social Positionality Index Scores was associated with a 21% reduction in the odds that they knew about U = U (aOR: 0.79 [0.73, 0.85], per 1-point increase). Results indicate that social marginalization harms the diffusion of HIV-related biomedical knowledge, independent of risk-taking behaviour and other factors.

Awareness and Acceptability of Undetectable = Untransmittable Among a U.S. National Sample of HIV-Negative Sexual and Gender Minorities

While the "Undetectable = Untransmittable" (U=U) message is widely endorsed, little is known about its breadth and reach. Our study describes socio-demographic characteristics and sexual behaviors associated with having heard of and trusting in U =U in a U.S. national sample of HIV-negative participants. Data were derived from the Together 5,000 cohort study, an internet-based U.S. national cohort of cis men, trans men and trans women who have sex with men. Approximately 6 months after enrollment, participants completed an optional survey included in the present cross-sectional analysis (n = 3286). Measures included socio-demographic and healthcare-related characteristics; questions pertaining to knowledge of and trust in U=U (dependable variable). We used descriptive statistics and multivariable logistic models to identify characteristics associated with these variables and explored patterns in willingness to engage in condomless anal sex (CAS) with regard to trust in U=U. In total, 85.5% of participants reported having heard of U=U. Among those aware of U=U, 42.3% indicated they trusted it, 19.8% did not, and 38.0% were unsure about it. Latinx, Asian, lower income, and Southern participants were less likely to have heard of U=U. Having had a recent clinical discussion about PrEP or being a former-PrEP user were associated with trust in U=U. Willingness to engage in CAS was positively associated with trust in U=U, and varied based on the partner's serostatus, PrEP use and viral load. Although we found high rates of awareness and low levels of distrust, our study indicated that key communities remain unaware and/or skeptical of U=U.

Poor quality of life and incomplete self-reported adherence predict second-line ART virological failure in resource-limited settings

We evaluated health-related quality of life (QoL) and self-reported incomplete adherence as predictors of early second-line antiretroviral (ART) virological failure (VF). ACTG A5273 study participants completed the ACTG SF-21 measure which has 8 QoL domains. We used exact logistic regression to assess the association of QoL at baseline and week 4 with early VF adjusted for self-reported adherence. Of 500 individuals (51% women, median age 39 years) in this analysis, 79% and 75% self-reported complete adherence (no missing doses in the past month) at weeks 4 and 24, respectively. Early VF was experienced by 7% and more common among those who self-reported incomplete adherence. Participants with low week 4 QoL scores had higher rates of early VF than participants with high scores. After adjusting for self-reported adherence at week 4, VL and CD4 at baseline, cognitive functioning, pain and mental health domains were significantly associated with subsequent early VF. In this post-hoc analysis, poorer QoL adds to self-reported incomplete adherence after 4 weeks of second-line ART in predicting VF at week 24. Evaluation is needed to assess whether individuals with poorer QoL might be targeted for greater support to reduce risk of VF.Trial registration: ClinicalTrials.gov identifier: NCT01352715.

A call to improve understanding of Undetectable equals Untransmittable (U = U) in Brazil: a web-based survey

INTRODUCTION

Currently, the slogan "Undetectable = Untransmittable" (U = U), launched to disseminate scientific evidence on how people living with HIV (PLHIV) on antiretroviral treatment with suppressed viral load cannot transmit HIV to their sexual partners, is still challenged by individuals with differential acceptance across populations. In this study, we documented the perceived accuracy of U = U in Brazil in three different groups: PLHIV, HIV-negative/unknown cisgender gay/bisexual men who have sex with men (GBM) and HIV-negative/unknown other populations (POP).

METHODS

Adult (age ≥ 18y) Brazilians were recruited during October 2019 to complete a web-based survey advertised on Grindr, Facebook and WhatsApp. Perceived accuracy of U = U was assessed with the question: "With regards to HIV-positive individuals transmitting HIV through sexual contact, how accurate do you believe the slogan U = U is?" Response options ranged from 1 (Completely inaccurate) to 4 (Completely accurate) plus a fifth option (I don't know what "undetectable" means). Participants' characteristics were described according to perceived accuracy of U = U. Logistic regression models assessed the factors associated with perceived accuracy of U = U (completely accurate vs. partially accurate/inaccurate or completely inaccurate) by group.

RESULTS

Of 2311 individuals accessing the questionnaire, 1690 (73.1%) met inclusion/exclusion criteria and completed it. Of these, 347 (20.5%) were PLHIV, 785 (46.4%) GBM and 558 (33.0%) POP. More PLHIV perceived U = U as completely accurate (79.0%), compared to 44.2% GBM and 17.2% POP (p < 0.001). Among PLHIV, Black identity was associated with decreased odds of perceiving U = U as completely accurate while having a steady partner was associated with increased odds. Among GBM, being gay, having middle/higher income, being a resident of state capital metropolitan areas and ever testing for HIV were associated with increased odds. Lastly, among POP, ever testing for HIV increased the odds of perceiving U = U as completely accurate.

CONCLUSIONS

There was a significant difference in perceived accuracy of U = U across population groups. Accurate understanding of the slogan needs to be promoted in more vulnerable populations such as PLHIV of Black identity and GBM of lower income to maximize individual and societal prevention benefits. Moreover, broader understating of U = U among the general population can help decrease societal stigma towards PLHIV.

"I just believe there is a risk" understanding of undetectable equals untransmissible (U = U) among health providers and HIV-negative partners in serodiscordant relationships in Kenya

Introduction

Sustained HIV viral suppression resulting from antiretroviral therapy (ART) eliminates the risk of HIV transmission, a concept popularly framed as Undetectable = Untransmittable (U = U). We explored knowledge and acceptance of information around the elimination of HIV transmission risk with ART (U = U) in Kenya.

Methods

Our qualitative study was conducted within a project evaluating the use of pre‐exposure prophylaxis (PrEP) integrated into ART care for HIV serodiscordant couples in public clinics in Kenya (the Partners Scale Up Project). From February 2017 to April 2019, we conducted semi‐structured key informant interviews with 83 health providers and in‐depth interviews with 61 HIV‐negative people in serodiscordant relationships receiving PrEP services. Transcripts were coded using thematic analysis.

Results

Health providers reported being aware of reduced risk of HIV transmission as a result of consistent ART use and used words such as “very low,” “minimal” and “like zero” to describe HIV transmission risk after viral suppression. Providers reported finding viral load results helpful when counselling clients about the risk of HIV transmission. Many lacked confidence in U = U and counselled on consistent condom use even after viral suppression while some expressed concerns that communicating this message to people living with HIV (PLHIV) would lead them to engage in multiple sexual relationships. Other providers reported that they did not counsel about the reduced risk of HIV transmission after viral suppression for fear of being blamed if HIV transmission occurred. HIV‐negative partners reported being informed about U = U by providers but they did not believe nor trust the message. Even after their partners achieved viral suppression, some HIV‐negative partners were unwilling to stop PrEP, while others indicated that they would use condoms if they stopped PrEP to be sure that they were protected from HIV.

Conclusions

Despite awareness that effective ART use eliminates HIV transmission risk, there is both a lack of in‐depth knowledge and conviction about the strategy among health providers and HIV‐negative partners in serodiscordant relationships. New strategies that go beyond communicating the science of U = U to consider the local social and clinical environments could maximize the effectiveness of U = U.

Treatment Is More Than Prevention: Perceived Personal and Social Benefits of Undetectable = Untransmittable Messaging Among Sexual Minority Men Living with HIV

Research suggests that the science of undetectable viral load (VL) status and HIV transmission-conveyed with the slogan "Undetectable = Untransmittable" or "U = U"-has gaps in acceptance despite robust scientific evidence. Nonetheless, growing acceptance of U = U creates conditions for a shift in the sociopolitical and personal implications of viral suppression. We conducted an online survey over a 23-month period in 2018 and 2019 among 30,361 adolescent and adult (aged 13-99) sexual minority men living with HIV (SMM-LHIV) across the United States. We examined the impact of U = U on self-image, potential for changing societal HIV stigma, whether SMM-LHIV had ever spoken with a provider about viral suppression and HIV transmission, and primary sources of hearing about U = U. Approximately 80% of SMM-LHIV reported that U = U was beneficial for their self-image and societal HIV stigma, 58.6% reported it made them feel "much better" about their own HIV status, and 40.6% reporting it had the potential to make HIV stigma "much better." The most consistent factors associated with these beliefs centered around care engagement, particularly self-reported viral suppression and excellent antiretroviral therapy adherence. Two-thirds reported ever talking to a provider about VL and HIV transmission, although the primary sources for having heard about U = U were HIV and lesbian, gay, bisexual, transgender, and queer (LGBTQ) news media and personal profiles on networking apps. These findings demonstrate the significant personal and social importance of U = U for SMM-LHIV that go above-and-beyond the well-documented health benefits of viral suppression, suggesting that providers should consider routinely initiating conversations with patients around the multifaceted benefits (personal health, sexual safety and intimacy, increased self-image, and reduced social stigma) of viral suppression.

Implementing a Status-Neutral Approach to HIV in the Asia-Pacific

PURPOSE OF REVIEW

Globally, "undetectable equals untransmittable (U=U)" and "pre-exposure prophylaxis (PrEP)" have become crucial elements in HIV treatment and prevention programs. We reviewed the implementation of U=U and PrEP among countries in the Asia-Pacific region.

RECENT FINDINGS

U=U and PrEP uptakes were limited and slow in the Asia-Pacific. Inadequate knowledge among health care practitioners and pervasive stigma towards individuals living with HIV and their sexual lives are key barriers for the integration of U=U into clinical practice. Paternalistic and hierarchical health care systems are major obstacles in PrEP implementation and scale-up. Countries with the most advanced PrEP implementation all use community-based, nurse-led, and key population-led service delivery models. To advance U=U and PrEP in the Asia-Pacific, strategies targeting changes to practice norm through wide-scale stakeholders' training and education, making use of online health care professional influencers, and utilizing financial mechanism should be further explored through implementation research.

HIV Treatment Knowledge in the Context of "Treatment as Prevention" (TasP)

According to 2012 universal ART guidelines, as part of "treatment as prevention" (TasP), all people living with HIV (PLWH) should immediately initiate antiretroviral therapy post-diagnosis to facilitate viral suppression. PLWH who are virally suppressed have no risk of sexually transmitting HIV. This study used descriptive analysis of quantitative data (N = 99) and thematic analysis of qualitative interviews (n = 36) to compare participants recruited from a hospital-based detoxification (detox) unit, largely diagnosed with HIV pre-2012 (n = 63) vs. those recruited from public, urban sexual health clinics (SHCs), mainly diagnosed in 2012 or later (n = 36). Detox participants were significantly more knowledgeable than SHC participants about HIV treatment, except regarding TasP. SHC participants' desire for rapid linkage to care and ART initiation was in line with 2012 universal ART guidelines and TasP messaging regarding viral suppression. More targeted messaging to PLWH pre-2012 could ensure that all PLWH benefit from scientific advances in HIV treatment.

Growing Acceptability of Undetectable = Untransmittable but Widespread Misunderstanding of Transmission Risk: Findings From a Very Large Sample of Sexual Minority Men in the United States

BACKGROUND

Several studies have demonstrated no linked HIV transmissions in serodifferent sexual encounters where the partner with HIV has an undetectable viral load. As a result, awareness and dissemination of treatment as prevention, and movements such as "Undetectable = Untransmittable" (U = U), has grown.

SETTING

We conducted an online cross-sectional survey from November 2017 through September 2018 to gather data from a total of 111,747 sexual minority men (SMM) in the United States.

METHODS

Participants provided sociodemographic data and answered questions regarding biomedical status, HIV and STI prevention behaviors, drug use, condomless anal sex, and perceived accuracy of the U = U message. We conducted analyses to understand factors associated with perceived accuracy of U = U stratified by HIV status.

RESULTS

Overall, 53.2% of the sample perceived U = U as accurate, with the highest rates among HIV-positive SMM (83.9%), followed by HIV-negative (53.8%) and status-unknown (39.0%) SMM. Multivariable models showed accuracy beliefs were, on average, 1-2% higher for each consecutive month of recruitment. Consistent with previous work, there was greater heterogeneity among HIV-negative and unknown men, with several factors differentiating perceived accuracy, compared with SMM with HIV. Perceived transmission risk levels with undetectable partners were skewed well above accurate levels, and greater perceived transmission risk was associated with lower perceived accuracy of U = U.

CONCLUSIONS

Public confidence in treatment as prevention and U = U is growing, but clear, unequivocal messaging about the effectiveness of U = U is critical. Owing to misunderstandings of risk, language that focuses on protective benefits rather than transmission risks may reach more people and allow for better comparisons with PrEP and condoms.

Stages of Adoption of "Treatment as Prevention" Among HIV-Negative Men Who Have Sex with Men Who Engage in Exchange Sex

Prior research found low acceptability of HIV treatment as prevention (TasP; or Undetectable = Untransmittable) among HIV-negative men who have sex with men (MSM). This study reports on qualitative data regarding TasP adoption in a sample of 170 self-reported HIV-negative MSM who had engaged in exchange sex (received money, drugs, or other things in exchange for sex). We classified participants along five stages of TasP adoption: 1-unaware of TasP (11.2%); 2-aware, but perceived ineffective (17.1%); 3-perceived effective, but unwilling to use (35.3%); 4-willing to rely on TasP, but had never done so (24.1%); and 5-had relied on TasP (12.4%). Obstacles to TasP adoption included the following: not believing that it could completely prevent HIV transmission; deeply ingrained fears of HIV/AIDS; concerns about viral load fluctuation; and reluctance to trust a partner's claimed undetectable status. TasP promotion efforts, which can decrease barriers to HIV testing and HIV stigma, will be more effective if tailored to the obstacles specific to each stage of TasP adoption.

Clinical Outcomes of Post-exposure Prophylaxis following Occupational Exposure to Human Immunodeficiency Virus at Dental Departments of Hiroshima University Hospital

Background

Dental professionals have so many opportunities to use injection needles and sharp instruments during dental treatment that they face an increased risk of needlestick injuries. This retrospective study reports the utilization and clinical outcomes of occupational post-exposure prophylaxis (PEP) with anti-retroviral agents after being potentially exposed to HIV at the dental departments of Hiroshima University Hospital.

Objective

This study reports the utilization and clinical outcomes of occupational post-exposure prophylaxis (PEP) with antiretroviral agents after being potentially exposed to HIV at dental departments of Hiroshima University Hospital.

Methods

Data on the clinical status of HIV-infected source patients and information on HIV-exposed dental professionals from 2007 to 2018 were collected.

Results

Five dentists with an average experience of 5.6 years (1-15 years) were exposed. The averaged CD4-positive cell number and HIV-RNA load were 1176 (768-1898) /μl and less than 20 copies/ml, respectively, in all the patients. Two of the five HIV exposed dentists received PEP. Three months after the exposures, all of their results were negative in HIV antibody/antigen tests.

Conclusion

These data might support the concept of “undetectable equals untransmittable”, although HIV exposure in this study was not through sexual transmission.

HIV Preexposure Prophylaxis and Treatment as Prevention - Beliefs and Access Barriers in Men Who Have Sex With Men (MSM) and Transgender Women: A Systematic Review

Purpose

While the annual rate of new HIV infections and diagnoses has remained stable for most groups, troubling increases are seen in transgender women and racial/ethnic-minority men who have sex with men (MSM), groups that are disproportionately affected by HIV. The primary purpose of this systematic review is to examine factors that impact attitudes and beliefs about preexposure prophylaxis (PrEP) and treatment as prevention (TasP) and to explore barriers to PrEP uptake in MSM and transgender women.

Methods

Using MeSH terms and relevant keywords, we conducted a systematic review of studies published between 2010 and 2019. We searched 4 literature databases and identified studies on MSM and transgender women to elucidate perceptions of PrEP and TasP as well as barriers to access.

Results

The search yielded several prominent themes associated with beliefs about HIV prevention approaches and barriers to PrEP access in MSM and transgender women. One was a lack of awareness or insufficient knowledge of PrEP and TasP. Structural barriers and geographic isolation also prevent access to HIV prevention. Sexual minority and HIV-related stigma, internalized homonegativity, and misinterpretations of messages within HIV prevention campaigns have negatively impacted PrEP uptake and beliefs about PrEP and TasP. Quality of the relationship MSM or transgender people have with their health care provider can facilitate or hinder HIV prevention. Finally, variability in beliefs about the efficacy of TasP has negatively affected the impact of TasP messaging campaigns.

Conclusions

Although there is evidence of increasing PrEP use in at-risk individuals, several barriers prevent wider acceptance and uptake. Misunderstanding about the meaning of "undetectable" and skepticism about the evidence behind TasP messaging campaigns are likely to delay the World Health Organization's stated goal of getting to zero transmissions.

Awareness and Perceived Accuracy of Undetectable = Untransmittable: A Cross-Sectional Analysis With Implications for Treatment as Prevention Among Young Men Who Have Sex With Men

The Undetectable = Untransmittable (U=U) campaign was launched in 2016 to simultaneously reduce human immunodeficiency virus (HIV) stigma and raise awareness about treatment as prevention. This research note assesses HIV-negative young men who have sex with men's U=U awareness and perceived accuracy to inform this population's combination HIV prevention strategies.

Sociodemographic and behavioural factors associated with testing for HIV and STIs in a US nationwide sample of transgender men who have sex with men

OBJECTIVES

Transgender men who have sex with men (TMSM) represent an understudied population in relation to screening for HIV and sexually transmitted infections (STIs). We examined HIV and STI testing prevalence among TMSM along with the factors associated with testing in a diverse US nationwide sample of TMSM.

METHODS

Data from a cross-sectional online convenience sample of 192 TMSM were analysed using multivariable binary logistic regression models to examine the association between sociodemographic and behavioural factors and lifetime testing for HIV, bacterial STIs and viral STIs, as well as past year testing for HIV.

RESULTS

More than two-thirds of TMSM reported lifetime testing for HIV (71.4%), bacterial STIs (66.7%), and viral STIs (70.8%), and 60.9% had received HIV testing in the past year. Engaging in condomless anal sex with a casual partner whose HIV status is different or unknown and having fewer than two casual partners in the past 6 months were related to lower odds of lifetime HIV, bacterial STI, viral STI and past year HIV testing. Being younger in age was related to lower probability of testing for HIV, bacterial STIs and viral STIs. Furthermore, TMSM residing in the South were less likely to be tested for HIV and viral STIs in their lifetime, and for HIV in the past year. Finally, lower odds of lifetime testing for viral STIs was found among TMSM who reported no drug use in the past 6 months.

CONCLUSIONS

These findings indicate that a notable percentage of TMSM had never tested for HIV and bacterial and viral STIs, though at rates only somewhat lower than among cisgender MSM despite similar patterns of risk behaviour. Efforts to increase HIV/STI testing among TMSM, especially among those who engage in condomless anal sex, are needed.

Belief, Covariates, and Impact of the "Undetectable = Untransmittable" Message Among People Living with HIV in Australia

There is effectively no risk of transmission of HIV from an HIV-positive person with consistent undetectable viral load (UDVL) to an HIV-negative person during sex. This has been publicly disseminated by an international health campaign called "undetectable = untransmittable" (U = U). This study extends previous research by examining confidence in the U = U message and potential covariates of confidence in U = U, as well as by assessing the perceived personal risk and sexual outcomes in a sample of people living with HIV (PLWH) in Australia. Between October 2017 and June 2018, 139 adult PLWH were recruited through clinics or community-based strategies. They completed an online questionnaire assessing participant characteristics, general agreement with the U = U message, confidence in U = U as an effective HIV prevention strategy, perceived personal risk of onward transmission, and sexual outcomes. While the majority of participants (70.5%) agreed with the general U = U message, only 48.2% were confident in U = U as an effective HIV transmission prevention strategy across sexual situations. Lack of confidence in U = U was more pronounced in the community subsample, minority group participants, and lower educated participants. A minority of PLWH with self-reported UDVL thought they could pass on HIV and indicated poor sexual outcomes, including sexual inactivity, reduced frequency of sex, and reduced sexual satisfaction. General agreement with the U = U message among PLWH may mask lack of confidence in U = U. Community-based information and education tailored to culturally diverse groups and people with low health literacy are required to promote accurate perception of risk of transmission of HIV with consistent UDVL.

Errors in Condom Use in the Setting of HIV Transmission: A Systematic Review

Background:

The efficacy of condom use in declining HIV transmission may be compromised by their incorrect usage. Much focus has been paid on the regularity of condom usage but consumer mistakes and challenges must be considered. Breakage, slipping, leakage, incomplete use and other problems during the sexual event may compromise the protective role of the condom.

Objective:

To evaluate through a systematic review of published data, the type, and incidence of error and problems in condom use, and their possible role in reducing the preventive action of condoms.

Methods:

A systematic literature search for peer-reviewed articles published between January 2000 and January 2019, issued in English in peer-reviewed journals, and reporting the occurrence of condom errors/problems among HIV high-risk populations.

Results:

Twenty studies representing nine countries met the inclusion criteria. The most predominant mistakes associated with condom use included condom breakage, slippage, delayed condom application, early removal, issues related to erection loss and difficulties with fit and feel were reported, failure to squeeze out air, use of expired condoms, reuse of condom, and wearing the condom outside out were other issues noticed.

Conclusions:

Condom use problems and mistakes are prevalent across the globe. Educational efforts are needed to empower HIV the at-risk population with confidence and knowledge to improve correct condom use and increase preventive activity

"Do I need to or do I want to?" A typology of HIV status disclosure among gay, bisexual, and other men who have sex with men

Gay, bisexual, and other men who have sex with men (GBMSM) are a key population that is disproportionately affected by HIV. However, few studies have explored how and why disclosure of HIV status occurs in this population. To understand disclosure in the context of other socioecological factors, we conducted a qualitative study among 24 self-identified HIV-positive GBMSM, aged 21 and above, and who were Singaporean residents. Analysis of participants' interviews revealed that disclosure of HIV status was not a binary event; rather, each type of disclosure held varying degrees of positive and negative ramifications. Disclosure and self-acknowledgement of HIV status at each time point also had different consequences for participants' quality of life. Suggested potential interventions include increasing training for medical professionals and public awareness surrounding issues relating to HIV. Findings from this study provide a framework to describe the complexities that accompany serostatus disclosure in a setting where there are prevalent "shame-based", negative attitudes towards HIV. As such, this framework can also be utilized in the future planning and organization of services for this target population in similar contexts.

Differences Between Groups of Pre-exposure Prophylaxis (PrEP) Using Couples in HIV-Negative/Unknown Relationships

BACKGROUND

Epidemiology research is limited on the characteristics of HIV pre-exposure prophylaxis (PrEP) using couples.

SETTING

US nationwide sample recruited online in 2017.

METHODS

HIV negative/unknown gay, bisexual, and other men who have sex with men with HIV negative/unknown partners (n = 3140) were asked about individual and main partner PrEP uptake. Men were coded into the following 5 groups: (1) neither participant nor partner on PrEP, (2) partner only on PrEP, (3) participant only on PrEP, (4) both on PrEP, and (5) unknown partner PrEP use. We examined associations of demographics, relationship factors, condomless anal sex (CAS) with main and causal partners, bacterial sexually transmitted infection diagnoses, and sexual positioning with reported dyadic PrEP use using fully adjusted multinomial logistic regressions.

RESULTS

PrEP use was 3.2% for the partner only, 5.7% for the participant only, and 4.9% for both the participant and partner; 5.6% reported not knowing their partner's PrEP use status. Men who reported any CAS with their main partner or any CAS with male casual partners were both more likely to be classified in the dyadic PrEP use group compared with the neither on PrEP group. Compared with monogamous, men in open arrangements were more likely to be classified in each of the 3 PrEP groups compared with the neither on PrEP group. Six-month bacterial sexually transmitted infection prevalence was 2.8%, 8.1%, 8.3%, 15.6%, and 4.0% for the 5 groups, respectively.

CONCLUSIONS

PrEP use occurred during times of higher risk behavior engagement, but further efforts are needed to expand PrEP use to more partnered gay, bisexual, and other men who have sex with men.

A theoretical examination using governmentality to understand gay men’s risk and sexual behaviours

This article explores the link between Foucault’s (1991) governmentality theory, specifically as it relates to gay men’s sexual practices and perceptions of HIV risk. Foucault’s (1991) theory of governmentality elucidates the means through which individual behaviours and norms (at a micro level) are governed through the production of disciplinary norms and structures that are instantiated at a broader structural and institutional level (the macro-level). Foucauldian theoretical conversations pertaining to what is meant by conceptions and definitions of HIV/STI risk are furthered through this paper’s theoretical contributions as they relate to gay men. From a Foucauldian perspective, we assess how gay men may alter or monitor their sexual practices through governmental scripts produced at a state level and manifested through micro- and macro-level behavioural and ideological shifts based on dominant socio-sexual norms. A model of the interrelationship between governmentality, scripting, the micro/macro levels, and the situation-specific is presented for future consideration when examining gay men’s sexual practices. Historical oppression and segregation of gay men are considered when exploring these theories from a critical social scientific lens.

Physician Mistrust, Medical System Mistrust, and Perceived Discrimination: Associations with HIV Care Engagement and Viral Load

Medical mistrust is an important risk factor for many health outcomes. For individuals with HIV and substance use co-morbidities, mistrust may influence engagement with health care, and affect overall health and transmission risk. Medical mistrust can be measured by an individual's mistrust of his/her physician, or mistrust of the medical system. This study examined both types of mistrust among 801 substance-using individuals with uncontrolled HIV infection. The aims were to determine how physician mistrust, medical system mistrust, and discrimination experiences were associated with engagement in HIV primary care. Findings indicated higher levels of physician mistrust, but not medical system mistrust, were associated with a longer time since the last visit to an HIV provider. Longer time since seeing an HIV care provider was associated with higher viral load. This study refines our understanding of the relationship between mistrust and HIV care engagement for a large, diverse sample of substance-using individuals.

Awareness and Perceived Effectiveness of HIV Treatment as Prevention Among Men Who Have Sex with Men in New York City

To assess perceptions of HIV treatment as prevention (TasP), we conducted an online survey of MSM in New York City (n = 732) asking them to rate the effectiveness of different strategies to reduce HIV risk during serodiscordant condomless anal sex between men. Only 6.1% reported not knowing what TasP was, with significantly less awareness among non-gay-identified MSM, men with less education, men who reported fewer anal sex partners in the prior 3 months, and HIV-negative/unaware men who had never used PrEP. The strategy most frequently perceived to offer "a lot" or "complete" protection from HIV was daily PrEP (70.0%), followed by TasP (39.1%), intermittent PrEP (16.6%), strategic positioning (15.8%), and withdrawal before ejaculation (10.8%). Men who were HIV positive, who had ever used PrEP, and who identified as gay/homosexual were significantly more likely to see TasP as effective. Further studies should investigate MSM's apparent skepticism towards TasP.

Factors associated with perceived accuracy of the Undetectable = Untransmittable slogan among men who have sex with men: Implications for messaging scale-up and implementation

INTRODUCTION

Recent research has shown high efficacy of HIV treatment for reducing the risk of HIV transmission to sexual partners. As the efficacy of treatment as prevention (TasP) has proliferated, a new messaging campaign, Undetectable = Untransmittable, has been gaining popularity. The purpose of this paper was to assess factors associated with the perceived accuracy of this TasP messaging strategy among a large and diverse sample of gay, bisexual, and other men who have sex with men (GBMSM) in order to inform subsequent efforts at large-scale and implementation of the HIV prevention message.

METHODS

We conducted a nationwide survey of GBMSM in the U.S. recruited from an online social networking site and a mobile sexual networking app. We analysed data from 12,222 GBMSM separately by HIV status to examine sociodemographic and behavioural factors associated with ratings of the accuracy of the Undetectable = Untransmittable message, which included the option to indicate not understanding what "undetectable" meant.

RESULTS

Among HIV-negative and unknown men, multivariable linear regression indicated that being on pre-exposure prophylaxis (PrEP), identifying as gay or queer (versus bisexual or straight), recent serodiscordant condomless anal sex (CAS), testing every six months or more often, less concern about sexually transmitted infection (STI) infection, and lower perceived risk of HIV infection were the factors with the largest independent effect on rating the Undetectable = Untransmittable statement as more accurate. Fewer factors emerged as associated with accuracy ratings among HIV-positive participants-reporting an undetectable viral load, a lifetime acquired immune deficiency syndrome (AIDS) diagnosis, and lower concern about STI infection were the factors most strongly associated with rating the statement as more accurate.

CONCLUSIONS

The findings of the current study highlight variability in the perceived accuracy of the Undetectable = Untransmittable message, suggesting potential subgroups who might benefit from targeted educational campaigns, perhaps broadcast utilizing sexual networking apps. Numerous factors, particularly among HIV-negative and unknown GBMSM, were associated with rating the message as more accurate. In particular, being on PrEP and testing regularly were two of the variables most strongly associated with higher accuracy ratings among HIV-negative GBMSM, suggesting HIV prevention services as potential points of intervention for increasing HIV knowledge and decreasing HIV stigma.

Changing Sources of Stigma against Patients with HIV/AIDS in the Rapid Expansion of Antiretroviral Treatment Services in Vietnam

Stigmatization against HIV/AIDS greatly hinders efforts to increase the accessibility and utilization of HIV/AIDS services to meet the 90-90-90 goal. This study assessed the stigmatization and discrimination experienced by people living with HIV (PLWH) across multiple social settings such as family, community, and healthcare facilities in Vietnam. A total of 1,016 patients (63.8% males, mean age = 35.4) participated in a cross-sectional study using a culturally tailored HIV stigma measure in three HIV-epidemic-concentrated cities in Vietnam. Zero-inflated Poisson models were used to examine factors associated with the number of types of stigma that patients experienced. 86.2% PLWH reported experiencing stigma against HIV/AIDS, more frequently from their community (62.8%) and family (30.2%) than from health care facilities (8%). The level of stigma from community reported by PLWH is associated with socioeconomic status (e.g., income, occupation). The poor and middle economic classes and unemployed patients reported more stigmatization and discrimination from the community. Across all settings, PLWH experienced fewer stigmatization over the course of ART indicating the benefits of rapidly expanded ART programs. PLWH reported more stigmatization and discrimination at the provincial level of the health administration. Those with the history of drug injection reported significantly less stigmatization from healthcare setting. More culturally tailored interventions to reduce stigmatization overall to improve the quality of life and health outcomes of PLWH should be warranted to achieve the 90-90-90 goal. Improving HIV-related knowledge of the general population and providing opportunities for PLWH to be reintegrated into should be considered. Using mass media with positive messages and images would also foster positive attitudes towards HIV/AIDS among the population and could potentially change social values. Continuous training of health staffs' attitude could minimize the occurrence of stigmatization and discrimination at healthcare facilities.

Adaptive Antiretroviral Therapy Adherence Interventions for Youth Living With HIV Through Text Message and Cell Phone Support With and Without Incentives: Protocol for a Sequential Multiple Assignment Randomized Trial (SMART)

BACKGROUND

Youth living with HIV (YLH) aged 13 to 24 years made up over a fifth (21%) of new HIV diagnoses in 2016, yet only 27% of YLH are virally suppressed. YLH have been shown to be poorly adherent to antiretroviral therapy (ART); however, there has been limited research investigating how to increase adherence in YLH. Mobile health (mHealth) interventions may be one promising way to do this.

OBJECTIVE

This study (ATN [Adolescent Trials Network] 144 SMART) aimed to compare adaptive interventions that could increase ART adherence in YLH aged 15 to 24 years. This includes mHealth initiatives, the tapering of interventions, and the use of incentives. Cost-effectiveness of sequencing the interventions without incentives before providing incentives and the savings on societal costs due to suppressed viral loads will be determined. This protocol is part of the ATN Scale It Up program described in this issue by Naar et al.

METHODS

This study uses a Sequential Multiple Assignment Randomized Trial design. Approximately 190 participants are being recruited, enrolled, and randomized to either cell phone support or text message support. Both intervention groups receive 3 months of intervention, followed by a second randomization based on response to the intervention. Responders test tapering their intervention, and nonresponders test receiving incentives.

RESULTS

Data collection for this study is projected to begin in August 2018 and last until June 2020.

CONCLUSIONS

This is an innovative study, particularly in terms of population, intervention types, focus on cost-effectiveness, and recruitment. This study could be particularly effective in improving adherence in YLH while reducing long-term individual and societal costs.
