Abstract
Condoms continue to be used by many gay, bisexual, and other men who have sex with men (GBM) to reduce the risk of HIV transmission. However this is impacted by condom failure events, defined here as condom breakage and slippage. In a prospective, observational cohort study of 343 HIV serodiscordant male couples recruited through high HIV caseload clinics and hospitals between 2012 and 2016 in Australia, Brazil, and Thailand, condom failure rates and associated factors were analysed, including with the study partner versus other sexual partners. There were 717 reported instances of condom failure from an estimated total of 25,831 sex acts with condoms, from over 588.4 participant years of follow up. Of the HIV-negative partners (n = 343) in the study, more than a third (n = 117, 36.7%) reported at least one instance of condom failure with any partner type during study follow-up. Condom failure with their study partner was reported by 91/343 (26.5%) HIV-negative partners, compared with 43/343 (12.5%) who reported condom failure with other partners. In total, there were 86 events where the HIV-negative partner experienced ano-receptive condom failure with ejaculation, representing 12.0% of all failure events. In multivariable analysis, compared to Australia, HIV-negative men in Brazil reported a higher incidence risk rate of condom failure (IRR = 1.64, 95%CI 1.01-2.68, p = 0.046) and HIV-negative men who reported anal sex with other partners reported an increased risk of condom failure compared with men who only had sex with their study partner (IRR = 1.89, 95%CI 1.08-3.33, p = 0.025). Although at least one event of condom failure was reported by a significant proportion of participants, overall condom failure events represented a small proportion of the total condom protected sex acts.

Abstract
ABSTRACT This study investigated the factors associated with amplified HIV transmission risk among people living with HIV from a city in southeast Brazil. A cross-sectional study was conducted with 397 people living with HIV recruited in infectious diseases clinics. Data on risk of HIV transmission, sociodemographic characteristics, sexual behaviors, professional counseling, serological HIV status, HIV-related clinical data, and beliefs about risk of HIV transmission were collected through interviews and medical records. Hierarchical ordered multinomial regression analyses were performed. Amplified HIV risk transmission was associated with lower age, alcohol consumption before having sex, illicit drug use before sexual intercourse, and not receiving professional counseling about HIV transmission. The belief that HIV can be transmitted to a partner not living with HIV was associated with lower likelihood of amplified risk for HIV transmission. Our findings suggest the importance of minimizing substance use before having sex, professional counseling, and beliefs about HIV transmission on amplified HIV risk transmission.

Abstract
OBJECTIVE To assess changes in personal and relationship characteristics among HIV-positive Australian gay and bisexual men (GBM) as rates of antiretroviral therapy and knowledge and confidence regarding the effectiveness of viral suppression in preventing HIV transmission have increased. DESIGN Repeated behavioral surveillance of GBM recruited from venues, events, and online in 7 Australian states and territories. METHODS HIV-positive participants were included. Trends in demographics, HIV treatment, and relationship characteristics were assessed with binary and multivariable logistic regression. RESULTS A total of 3643 survey responses (2016-2020) were included. Over time, HIV-positive GBM became less likely to identify as gay or report an Anglo-Australian ethnicity. The average length of time since HIV diagnosis increased and the frequency of attending HIV-related clinical appointments decreased. There were no changes in the reported number of recent sex partners or proportion reporting regular male partners over time. Among HIV-positive GBM in relationships, the proportion reporting HIV-positive partners decreased and the proportion reporting HIV-negative partners increased. Levels of condomless sex with regular partners increased over time; however, this was concentrated among HIV-positive GBM in serodiscordant relationships. CONCLUSION Findings suggest that increased accessibility and trust in biomedical prevention strategies have contributed to broader relationship and sexual opportunities for HIV-positive GBM in Australia. Our findings suggest that future health promotion activities could highlight the social and relationship benefits of treatment as prevention to further increase trust in it as an HIV prevention strategy among GBM.

Abstract
The World Health Organization's (WHO) global public health mandate includes a focus on expanding access to HIV testing, antiretroviral therapy (ART) and treatment monitoring to improve the clinical management of HIV, achieve sustained viral suppression, and prevent HIV-related incidence, morbidity, and mortality. This article documents key moments in research and WHO policies that have informed how ART is applied within HIV programs, including as a prevention tool with the potential to support efforts to address HIV-related discrimination. For more than 20years, WHO has promoted the benefits of HIV treatment including as part of the approach to prevent the mother-to-child transmission (vertical transmission) of HIV. WHO guidance has followed, and continues to follow, the evolving evidence. In 2023, WHO continues to clarify that there is zero risk of sexual HIV transmission when a person living with HIV has an undetectable viral load and an almost zero or negligible risk of sexual transmission when a person living with HIV has a viral load of ≤1000copies/mL - helping to evolve the focus of community campaigns and health worker training to include a focus on 'virally suppressed' while also continuing to emphasise the ultimate goal of achieving an undetectable viral load. This evolution does two things: first, it strongly reasserts the evidence around there being no chance of transmission if a person has an undetectable viral load; and second, it provides an extremely strong degree of confidence that, similarly, individuals who are virally suppressed will not pass on the virus sexually. WHO is now encouraging positive and clear messaging to highlight that the consistent use of ART prevents onwards HIV transmission.

Abstract
Male HIV serodiscordant couples have diverse relationship agreements regarding sex outside the relationship. We examined the relationship agreements as described by 343 male HIV-negative partners in HIV serodiscordant relationships in Australia, Brazil and Thailand participating in a multi-year cohort study. At baseline, 125 (34.1%) HIV-negative partners reported no agreement, 115 (33.5%) had a monogamous agreement, and 103 (37.9%) had an open agreement allowing sex outside the relationship. Relationship agreements were largely stable over time, with 76% of HIV-negative men reporting the same agreement across follow up, while changes were predominantly towards having an open agreement. Behaviour largely matched relationship agreements, and the predictors of breaking an agreement by having condomless anal intercourse (CLAI) with an outside partner were CLAI within the relationship (OR = 3.17, 95%CI: 1.64-6.14, p < 0.001) and PrEP use in the last three months (OR = 3.42, 95%CI: 1.48-7.92, p = 0.004). When considering HIV transmission risk for HIV-negative men in serodiscordant relationships, greater focus needs to be placed on sex that is occurring outside the relationship and the agreements that facilitate this.

Attitudes Towards Treatment as Prevention Among PrEP-Experienced Gay and Bisexual Men in Australia. AIDS Behav 2023:10.1007/s10461-023-04019-x.

Abstract
The introduction of HIV pre-exposure prophylaxis (PrEP) has the potential to impact the attitudes gay and bisexual men (GBM) who consequently choose to take PrEP have towards treatment as prevention (TasP), and the extent to which they are willing to have condomless anal intercourse (CLAI) with an HIV-positive sexual partner who has an undetectable viral load (UVL). Using a cross-sectional sample from an observational cohort study conducted from August 2018 to March 2020, we examined the extent to which PrEP-experienced GBM are willing to have CLAI with a partner who has a UVL. Simple and multiple logistic regression models were used to identify associated variables. Of the 1386 participants included in the analyses, 79.0% believed in the effectiveness of TasP, and 55.3% were willing to have CLAI with a partner who has a UVL. Wiling participants were less worried about getting HIV when taking PrEP and more likely to believe in TasP. Further research is needed to better understand the gap between belief in TasP and willingness to have CLAI with a partner who has a UVL among PrEP-experienced GBM.

Abstract
Pre-exposure prophylaxis (PrEP) affords an opportunity to significantly reduce the risk of HIV infection among male couples. We used cross-sectional dyadic data from 382 concordant-negative male couples to examine demographic and relationship characteristics associated with current PrEP use, willingness to use PrEP in the future, and perceived ability to adhere to PrEP using Actor-Partner Independence Models. Few partnered men reported currently using PrEP (16.4%) and 57.7% of non-users reported being unlikely to use PrEP in the future. Actor and partner perceptions of PrEP stigma significantly reduced PrEP use and perceptions of willingness to use PrEP or the ability to adhere to PrEP, while perceiving a higher prevalence of HIV among men was associated with significant increases in PrEP use, willingness and perceived ability to adhere. Perceptions that more friends would support PrEP use were also significantly associated with increases in willingness and perceived ability to adhere to PrEP. Dyadic interventions are needed to provide couples the skills to communicate about HIV risk and prevention, and address myths around the protective effect of relationships against HIV acquisition.

Abstract
The use of undetectable viral load (VL) to negotiate condomless anal intercourse (CLAI) in HIV serodiscordant male relationships has become more common as more data regarding the effectiveness of antiretroviral treatments for the prevention of HIV transmission has been described. We examined viral load agreements (VLAs) for condomless sex in the presence of an undetectable VL in 343 HIV serodiscordant male couples in Australia, Brazil and Thailand. Factors associated with having a VLA included having agreements for the HIV-positive partner to report his VL result (p < 0.001), agreeing that VL affects agreements about sexual practice (p < 0.001), the HIV-negative partner's perception of his partner's undetectable VL (p < 0.001), the couple's belief in the efficacy of undetectable VL in preventing HIV transmission (p < 0.001), and the couple engaging in CLAI with each other (p < 0.001). Over time, these agreements became more common although 49.3% of couples in the sample never had a viral load agreement. As these agreements become more common, further education is required to support male couples in using them safely.

Abstract
Few studies have examined changes in sexual behaviour following HIV pre-exposure prophylaxis (PrEP) initiation among gay, bisexual and other men who have sex with men (GBM) in relationships. In a national, online, prospective study of GBM in Australia, we compared sexual behaviours prior to and after PrEP initiation among HIV-negative and unknown-HIV-status men (recruited 2014-2017) not taking PrEP at baseline and who completed at least one six-monthly follow-up by July 2018. Among men in relationships who did not initiate PrEP (n = 339), we compared their most recent survey to their prior one, while among men in relationships who initiated PrEP (n = 81), we compared follow-ups before and after PrEP initiation. Among the 81 PrEP-initiators who were in a relationship both before and after initiation, the proportion reporting their regular partner was on PrEP increased from 8.3 to 44.4% (p < 0.001) and the proportion reporting receptive CLAIC increased from 27.2 to 44.4% (p = 0.009). Overall, men who initiated PrEP were more likely to be in a relationship with a partner on PrEP, and it appeared they started PrEP around the same time. Receptive CLAIC also became more common.

[PMID: 34449742 PMCID: PMC8396300 DOI: 10.3390/tropicalmed6030139] [Citation(s) in RCA: 4] [Impact Index Per Article: 1.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/31/2021] [Revised: 07/07/2021] [Accepted: 07/21/2021] [Indexed: 11/17/2022] Open
Abstract
In recent years, prevalence of Human Immunodeficiency Virus (HIV) has increased substantially in Bali, Indonesia, in men who have sex with men (MSM) and transgender women, known locally as ‘waria’. There are limited behavioural data in this population. We conducted a behavioural survey of MSM/waria in Bali in March–April 2018. Respondents were primarily recruited by HIV outreach workers. Respondents reported details about anal intercourse events with their last male/waria romantic partner and/or last male/waria casual partner (respondents could report on both if relevant). Statistical significance was tested with generalised estimating equations. Among 709 participants, median age was 27 (interquartile range = 24–31), and 92.1% were male and 7.9% were waria. One-third were born in Bali. Overall, 85.9% had ever had an HIV test; 55.1% reported being HIV-negative, 15.0% HIV-positive, and 30.0% had unknown serostatus. Most (86.5%) reported sex with men, 9.5% with waria, and 20.0% with women in the previous 6 months. Respondents described 703 anal intercourse events (397/306 with romantic/casual partners, respectively; 191 reported on both). Over half (56.5%) of the events were protected by condoms and 7.3% by biomedical prevention (2.6% by PrEP in either partner, 4.7% by HIV treatments in either partner). Thus, 36.3% of events involved unprotected condomless anal intercourse (40.8%/30.4% in romantic/casual partners, respectively). In multivariate analysis, unprotected condomless anal intercourse events were associated with romantic partners (p < 0.001), being born in Bali (p = 0.002), lower education (p = 0.013), believing that withdrawal before ejaculation is effective (p < 0.001), liking to use withdrawal (p = 0.021), and not liking condoms (p < 0.001). One-quarter of events had potentially reduced HIV transmission risk through non-condom-based risk reduction strategies, while 11.1% had no potential risk reduction. Events presenting the highest potential risk of HIV transmission were more commonly reported by respondents born in Bali.

The Influence of Relationship Dynamics and Sexual Agreements on Perceived Partner Support and Benefit of PrEP Use Among Same-Sex Male Couples in the U.S. AIDS Behav 2020; 24:2169-2177.

Abstract
Use of Pre-exposure prophylaxis (PrEP) for HIV prevention by men who have sex with men (MSM) may be impacted by relationship dynamics. We assessed perceived partner support of PrEP use and benefit of PrEP by relationship characteristics among male couples. Baseline data from a randomized control trial of video-based HIV counseling and testing among male couples in the U.S. were used in adjusted multilevel regression models to assess individual and dyadic characteristics. Among 659 participants, 73.3% thought their partner would be supportive of their PrEP use; 26.7% reported their partner would not support PrEP use, which was significantly associated with intimate partner violence (IPV) (p = 0.008). Most (57.7%) did not believe PrEP would be beneficial to them or their partner. Couples with a sexual agreement allowing outside partners were significantly associated with higher perceived support of partners for PrEP (p < 0.001) and benefit of PrEP use (p < 0.001). Perceived partner support of PrEP was high but perceived benefit of PrEP was low, both shaped by relationship dynamics that highlight the need for tailored dyadic interventions. The association between perceived PrEP support and IPV points to the need to integrate relationship contexts in HIV prevention programs.

Abstract
This article aims to Identify factors associated with knowledge and use of combined HIV prevention strategies among female sex workers (FSW). Cross-sectional epidemiological study, using the Respondent Driven Sampling (RDS) method. Descriptive analyzes were performed after adjustments required by the RDS method. To investigate factors associated with knowledge of PEP and PrEP and use of the female condom, Poisson regression was applied, using odds ratio as an association measure. FSW not affiliated with NGOs, who did not receive informational material on prevention and / or participated in lectures in the last six months and who do not identify themselves as FSW in healthcare service facilities have less knowledge about PEP and PrEP and use the female condom less frequently. In general, FSW do not have sufficient knowledge and access to combined HIV prevention methods to take advantage of their benefits. We believe that the adoption of different models of care for FSW in partnership with NGOs can be an effective strategy for expanding knowledge and use of HIV prevention methods in Brazil.

Strategies used by gay male HIV serodiscordant couples to reduce the risk of HIV transmission from anal intercourse in three countries. J Int AIDS Soc 2020; 22:e25277. [PMID: 30983155 PMCID: PMC6462805 DOI: 10.1002/jia2.25277] [Citation(s) in RCA: 10] [Impact Index Per Article: 2.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/09/2018] [Accepted: 03/15/2019] [Indexed: 01/31/2023] Open
Abstract
INTRODUCTION There are few data about the range of strategies used to prevent sexual HIV transmission within gay male serodiscordant couples. We examined HIV prevention strategies used by such couples and compared differences between countries. METHODS Opposites Attract was a cohort study of male serodiscordant couples in Australia, Brazil and Thailand, from May 2014 (Australia) or May 2016 (Brazil/Thailand) to December 2016. At visits, HIV-positive partners had viral load (VL) tested; HIV-negative partners reported sexual behaviour and perceptions of their HIV-positive partner's VL results. Within-couple acts of condomless anal intercourse (CLAI) were categorized by strategy: condom-protected, biomedically protected (undetectable VL and/or pre-exposure prophylaxis [PrEP]), or not protected by either (HIV-negative partners engaging in insertive CLAI, receptive CLAI with withdrawal, or receptive CLAI with ejaculation). RESULTS A total of 343 couples were included in this analysis (153 in Australia, 93 in Brazil and 97 in Thailand). Three-quarters of HIV-positive partners were consistently virally suppressed (<200 copies/mL) during follow-up, and HIV-negative partners had correct perceptions of their partner's VL result for 76.5% of tests. One-third of HIV-negative partners used daily PrEP during follow-up. Over follow-up, 73.8% of couples had CLAI. HIV-negative partners reported 31,532 acts of anal intercourse with their HIV-positive partner. Of these, 46.7% were protected by condoms, 48.6% by a biomedical strategy and 4.7% of acts were not protected by these strategies. Australian couples had fewer condom-protected acts and a higher proportion of biomedically protected acts than Brazilian and Thai couples. Of the 1473 CLAI acts where the perceived VL was detectable/unknown and were not protected by PrEP (4.7% of all acts), two-thirds (n = 983) were when the HIV-negative partner was insertive (strategic positioning). Of the 490 acts when the HIV-negative partner was receptive, 261 involved withdrawal and 280 involved ejaculation. Thus, <1% of acts were in the highest risk category of receptive CLAI with ejaculation. CONCLUSIONS Couples used condoms, PrEP or perceived undetectable VL for prevention in the majority of anal intercourse acts. Only a very small proportion of events were not protected by these strategies. Variation between countries may reflect differences in access to HIV treatment, education, knowledge and attitudes.

Abstract
INTRODUCTION Men who have sex with men (MSM) are suboptimally engaged in efficacious HIV interventions, due in part to stigma. AIM We sought to validate the Anal Health Stigma Model, developed based on theory and prior qualitative data, by testing the magnitude of associations between measures of anal sex stigma and engagement in HIV prevention practices, while adjusting for covariates. METHODS We conducted a cross-sectional online survey of 1,263 cisgender MSM living in the United States and analyzed data with structural equation modeling. We tested a direct path from Anal Sex Stigma to Engagement in HIV Prevention alongside 2 indirect paths, 1 through Anal Sex Concerns and another through Comfort Discussing Anal Sexuality with Health Workers. The model adjusted for Social Support, Everyday Discrimination, and Sociodemographics. MAIN OUTCOME MEASURE Engagement in HIV Prevention comprised an ad hoc measure of (i) lifetime exposure to a behavioral intervention, (ii) current adherence to biomedical intervention, and (iii) consistent use of a prevention strategy during recent penile-anal intercourse. RESULTS In the final model, anal sex stigma was associated with less engagement (β = -0.22, P < .001), mediated by participants' comfort talking about anal sex practices with health workers (β = -0.52; β = 0.44; both P < .001), adjusting for covariates (R2 = 67%; χ2/df = 2.98, root mean square error of approximation = 0.040, comparative fit index = 0.99 and Tucker-Lewis index = 0.99). Sex-related concerns partially mediated the association between stigma and comfort (β = 0.55; β = 0.14, both P < .001). Modification indices also supported total effects of social support on increased comfort discussing anal sex (β = 0.35, P < .001) and, to a lesser degree, on decreased sex-related concerns (β = -0.10; P < .001). CLINICAL IMPLICATIONS Higher stigma toward anal sexuality is associated with less engagement in HIV prevention, largely due to discomfort discussing anal sex practices with health workers. STRENGTH & LIMITATIONS Adjustment for mediation in a cross-sectional design cannot establish temporal causality. Self-report is vulnerable to social desirability and recall bias. Online samples may not represent cisgender MSM in general. However, findings place HIV- and health-related behaviors within a social and relational context and may suggest points for intervention in health-care settings. CONCLUSION Providers' willingness to engage in discussion about anal sexuality, for example, by responding to questions related to sexual well-being, may function as social support and thereby bolster comfort and improve engagement in HIV prevention.
