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

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.

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.

Emotional Reactions to High-Risk Sex among Sexual Minority Men: Exploring Potential Opportunities for Just-In-Time Intervention

Rates of HIV and other sexually transmitted infections (STIs) are high among sexual minority men (SMM). A large body of research has explored determinants of HIV/STI risk behavior, but few studies have explored emotional consequences of these events. Understanding the valence, timing, and strength of emotional reactions to sexual risk could inform use of specific behavior change techniques in interventions (such as anticipated regret) and identify new opportunities for intervention, including just-in-time interventions. We analyzed data from an ecological momentary assessment (EMA) study of 100 HIV-negative/unknown-status SMM to understand patterns of positive affect, negative affect, shame, and stress in the 24 hours after sex. Mixed-effects models showed that the probability of negative affect was higher in the hours following condomless anal sex (CAS) with high-risk partners during which SMM reported being under the influence of alcohol or drugs (A/D involved CAS), versus all other types of sex events (OR = 0.92, SE = 0.03, p = .017). The probability of shame was also higher after A/D-involved CAS, versus other sex events (OR = 1.14, SE = 0.07, p = .035). Findings suggest that the hours following A/D-involved CAS events may be an opportune time to intervene to help SMM avoid similarly aversive experiences in the future.

Attitudes Towards Treatment as Prevention Among PrEP-Experienced Gay and Bisexual Men in Australia

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.

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.
