RESUMO

BACKGROUND: Despite highly effective HIV preexposure prophylaxis (PrEP) options, no options provide on-demand, nonsystemic, behaviorally congruent PrEP that many desire. A tenofovir-medicated rectal douche before receptive anal intercourse may provide this option. METHODS: Three tenofovir rectal douches-220 mg iso-osmolar product A, 660 mg iso-osmolar product B, and 660 mg hypo-osmolar product C-were studied in 21 HIV-negative men who have sex with men. We sampled blood and colorectal tissue to assess safety, acceptability, pharmacokinetics, and pharmacodynamics. RESULTS: The douches had high acceptability without toxicity. Median plasma tenofovir peak concentrations for all products were several-fold below trough concentrations associated with oral tenofovir disoproxil fumarate (TDF). Median colon tissue mucosal mononuclear cell (MMC) tenofovir-diphosphate concentrations exceeded target concentrations from 1 hour through 3 to 7 days after dosing. For 6-7 days after a single product C dose, MMC tenofovir-diphosphate exceeded concentrations expected with steady-state oral TDF 300 mg on-demand 2-1-1 dosing. Compared to predrug baseline, HIV replication after ex vivo colon tissue HIV challenge demonstrated a concentration-response relationship with 1.9 log10 maximal effect. CONCLUSIONS: All 3 tenofovir douches achieved tissue tenofovir-diphosphate concentrations and colorectal antiviral effect exceeding oral TDF and with lower systemic tenofovir. Tenofovir douches may provide a single-dose, on-demand, behaviorally congruent PrEP option, and warrant continued development. Clinical Trials Registration . NCT02750540.

RESUMO

For those most at risk of contracting HIV, new strategies for preventing transmission and increasing testing are needed. As part of a multi-site, randomized, controlled trial, we explored attitudes and preferences among 272 HIV-negative men who have sex with men and HIV-negative transgender women using an HIV self-testing (HIVST) kit to test partners. Less than one quarter had previously self-tested with HIVST kits (21.7%) and few had partner-tested (4.8%). Most preferred gum swab (96%) over fingerprick tests (69%), but would prefer a blood test if it gave results for other sexually transmitted infections (STIs) (86%). Five percent reported difficulties performing the test, four percent with storage, and 26% with portability. Ninety-three percent reported likelihood of using HIVST to test partners in future, but only 3% were willing to pay the current price. Efforts to improve HIVST uptake should focus on incorporating testing for other STIs, reducing test kit size, and reducing cost.


RESUMEN: Se necesitan nuevas estrategias para prevenir la transmisión del VIH e incrementar el testeo para aquellos con mayor riesgo al contagio. Como parte de un ensayo controlado aleatorio (ECA) multicentrico, exploramos las actitudes y preferencias entre 272 hombres VIH-negativos que tienen sexo con hombres y mujeres transgenero VIH-negativos que utilizaron kits del auto-test para el VIH (HIVST) para testear a sus parejas. Menos de una cuarta parte de los participantes había utilizado HIVST para auto-testearse (21.7%), y solo pocos para testear a sus parejas (4.8%) antes del comienzo del estudio. El hisopo bucal fue preferido (96%) sobre una prueba con un pinchazo de sangre (69%) por la mayoría de los participantes pero estos preferirían la prueba de sangre si puedieran obtener resultados para otras enfermedades de transmisión sexual (ETS) (86%). Cinco por ciento reportó problemas con el uso de la prueba, 4% con el almacenamiento, y el 26% con la portabilidad. Noventa y tres por ciento reportó que utilizarían HIVST para testear a sus parejas en el futuro, pero solo 3% estaba dispuesto a pagar el precio actual. Los futuros esfuerzos para mejorar la adopción del HIVST deberían enfocarse en incorporar otras pruebas de ETS, en reducir el tamaño del kit y en reducir los costos.

RESUMO

Men who have sex with men (MSM) and transgender women (TGW) are highly affected by HIV and need novel prevention strategies. Using HIV self-testing (HIVST) kits to screen sexual partners may represent a viable risk-reduction alternative; however, more research is needed on effective strategies for broaching HIVST with partners. In the ISUM study, 136 MSM and TGW were given ten HIVST kits for self- and partner-testing. After 3 months, they returned for a follow-up assessment; thirty participants were also selected for in-depth interviews about their experiences initiating HIVST with partners. Most found proposing HIVST to a diverse array of partners relatively easy. They employed strategies such as joint testing and integrating HIVST into larger discussions about protection and sexual health, with moderate success. Nonetheless, real or anticipated negative partner reactions were a significant barrier. Future research can inform best practices for safely and successfully broaching HIVST with sexual partners.


RESUMEN: Los hombres que tienen sexo con hombres (HSH) y las mujeres tránsgenero (MTG) están muy afectados por el VIH y necesitan estrategias innovadoras de prevención. El uso del autotest de VIH (HIVST) para testear a parejas sexuales podría ser una alternativa viable de reducir el riesgo; sin embargo, se necesitan más investigaciones sobre estrategias eficaces para abordar el tema de usar el HIVST con parejas. En el estudio ISUM, 136 HSH y MTG fueron provistos de diez HIVST para testear a sí mismo y a parejas. Después de tres meses, volvieron para una evaluación de seguimiento; treinta participantes también fueron seleccionados para una entrevista en profundidad sobres sus experiencias abordando el tema del uso del HIVST con parejas. La mayoría encontró que proponer HIVST a una gran variedad de parejas fue relativamente fácil. Emplearon estrategias como hacerse la prueba juntos y integrar HIVST en una conversación más amplia sobre la protección y la salud sexual, con leve éxito. No obstante, las reacciones negativas de parejas, ya sean reales o anticipadas, representaron una barrera importante. Las investigaciones futuras pueden informar las mejores prácticas para abordar el tema de HIVST con parejas sexuales de manera segura y exitosa.

RESUMO

HIV partner-testing (PT) may represent a unique and empowering HIV prevention strategy for groups that face structural and institutional barriers to HIV testing and care, including transgender women. We report on in-depth interviews (IDIs) with N = 10 transgender women who used HIV self-test kits for three months to screen potential sexual partners in a randomized controlled trial (iSUM; "I'll Show You Mine") that took place in New York City and San Juan, Puerto Rico. Participants were assigned to intervention (supplied with 10 self-test kits immediately) or control groups (received 6 test kits after 3 months). We conducted IDIs with the first N = 10 transgender women to enroll in the intervention group after three months in the study (after participants used kits with partners) to understand their experiences. Themes discussed in IDIs included: partners' reaction to HIV testing, participants' reactions to partners' test results or refusal to test, partners' own reaction to their test results, and decision-making around test use. Data were independently analyzed by two coders. Overwhelmingly, participants' experiences with PT was positive. Participants reported kits were convenient and acceptable to most partners. Transgender women felt that PT could pose additional risk for them; one woman experienced violence related to kit use. Furthermore, the availability of kits appeared to encourage participants and their partners to think about their HIV status and, in some cases, modify sexual behavior. Work suggests that HIV PT could be a viable risk-reduction strategy for transgender women.

RESUMO

HIV self-tests (HIVST) provide the possibility of testing partners prior to sexual activity. This study examines the role of substance use among men who have sex with men (n = 123) and transgender women (n = 13) who were provided HIVST to use with potential sex partners. Several reported avoiding/delaying alcohol (44%) or drug use (27%) because they intended to use HIVST. Those who used HIVST with alcohol (37%) or drugs (24%) did not differ from those who did not on number of partners asked, proportion who agreed, or intentions to use HIVST. A minority reported problems caused by substances. Ten did not ask someone to test because they were too drunk/high. Fourteen said it was fairly or very hard to use HIVST when under the influence. Eleven reported substances caused problems when discussing or administering HIVST, but only two of those felt the problems were major.

RESUMO

Secondary distribution of HIV self-tests to sexual partners is acceptable but concerns remain about reactions if a partner tests HIV-positive. We report on 14 participants whose sexual partners tested HIV-positive during the "I'll Show You Mine" Study, a randomized controlled trial (N = 272) of HIV self- and partner-testing among men who have sex with men (MSM) and transgender women (TGW). All 14 were MSM and racial/ethnic minorities, mean age was 36.6 years; 86% were gay-identified. Twenty-four partners tested positive; about half were new partners. Six participants had multiple partners test positive. During in-depth interviews with 10 of these participants, they reported their partners' reactions ranged from tearful and worried among those whose result was unexpected, to resignation among those who suspected a positive result, to nonchalance among partners who participants concluded knew of their HIV infection. After testing, some HIV-positive partners disclosed prior knowledge of their status. No partner reacted violently. Participants typically comforted their partners and encouraged confirmatory testing. Four participants had anal intercourse with partners who tested positive. Participants and partners were able to effectively handle situations in which the partner tested HIV-positive.

RESUMO

Men who have sex with men and transgender women who had multiple sexual partners in the prior 3 months participated in ISUM, a randomized, controlled trial of self- and partner-testing in New York City and San Juan, PR. Only 2% of screened participants were ineligible to enroll due to anticipating they would find it very hard to avoid or handle violence. The intervention group received free rapid HIV self-test kits. During the trial, 114 (88%) of intervention participants who were assessed at follow-up used self-tests with at least one potential partner. Only 6% of participants who asked a partner in person to test reported that at least one of their partners got physically violent, some in the context of sex work. In total, 16 (2%) partners reacted violently. Post-trial, only one participant reported finding it very hard to handle violence, and none found it very hard to avoid potential violence.

RESUMO

Transgender female sex workers (TFSW) are highly affected by HIV, with a global prevalence of 27%. HIV self-testing (HIVST) to screen sexual partners has helped men who have sex with men and female sex workers make informed sexual decisions and avoid HIV exposure. This is the first report on TFSW's experiences screening clients using HIVST. Ten TFSW were each given ten HIVST kits and returned after 3 months to complete an online questionnaire and undergo an interview. Eight of them reported using HIVST with potential partners. Among fifty potential partners who were asked in person to test, 42 (84%) were clients. Thirty-four out of fifty (68%) accepted and 16 (32%) refused. Very few violent incidents occurred, and participants felt empowered by offering HIVST to others. Nevertheless, HIVST market cost was prohibitive for future use. HIVST use with clients could be feasible for TFSW if the cost were lowered or subsidized.

RESUMO

Human papillomavirus (HPV) prevalence varies by population. This study investigated anal HPV type detection risk by country in a population of men who have sex with men (MSM) and transgender women (TW) at risk of HIV. Sexually active HIV-1-uninfected MSM and TW were enrolled at eight sites: four in the United States (US), two in Thailand, one in Peru, and one in South Africa. Baseline anal HPV swabs were collected, and DNA typing was performed. One hundred and ninety-five participants, 76 (42%) from the US, had a mean age of 30.9 years (range 18-64). In 182 participants with results available, anal HPV infection was common with 169 (93%) with ≥1 type, 132 (73%) with ≥1 nine-valent vaccine types, and 66 (36%) with HPV 16. Participants in the US had a higher prevalence of HPV 16 (56%, p = 0.004) and HPV 6 (69%, p < 0.001) compared to the other regions. Stimulant drug use was significantly associated with HPV 6 detection. Anal HPV is highly prevalent in this population of MSM and TW sampled from four countries, with HPV 16 the most commonly detected type. The nine-valent HPV vaccine has the potential to provide significant protection if given prior to exposure.

RESUMO

BACKGROUND: Mobile Technology and Incentives (MOTIVES) is a randomized pilot study of a mobile technology-based and behavioral economics-supported HIV prevention intervention. Behavioral economics (BE) uses financial incentives in a way that departs from the traditional focus on large monetary payments. Instead, BE suggests that relatively small "nudges" can effectively initiate and sustain behavior change. This pilot study examines the feasibility and acceptability of an HIV prevention intervention that uses text messages in combination with BE incentives to improve retention of HIV prevention information and increase frequency of HIV testing among Latino/a men who have sex with men (MSM) and transgender women (TGW). The pilot will also estimate mission-critical design parameters with point and confidence interval estimates of the intervention to inform a future, fully powered effectiveness study. METHODS: The project will be conducted in collaboration with Bienestar Human Services, Inc. (Bienestar), a non-profit community-based service organization. The intervention is being tested in a small, randomized controlled trial to pilot the intervention's feasibility and acceptability among 200 Latino/a MSM and TGW from Bienestar's HIV testing sites. Information on feasibility will include recruitment, refusal, and retention rates as well as message sending success rates; acceptability will include perceived appropriateness based on responses to the intervention. Participants will be randomized into either the "information only" control group (e.g. receiving text messages with HIV prevention information) or the "information plus" intervention group (e.g. additionally receiving quiz questions that provide the possibility of winning prizes). Participants will be followed for 12 months from enrollment. In addition to using data abstracted from Bienestar's routine data collection mechanisms, we will also collect survey data (blinded outcome assessment) from participants at 0, 6, and 12 months to provide an initial assessment of whether incentives affect their level of HIV knowledge and testing frequency. DISCUSSION: If shown to be acceptable, feasible, and resource-efficient, MOTIVES will provide an innovative way to communicate the latest HIV prevention information and support trimestral HIV screening among Latino/a MSM and TGW.

RESUMO

In the United States young men who have sex with men have higher rates of substance use, higher HIV incidence, and less frequent HIV testing than their heterosexual counterparts and older MSM. Less is known about comparable populations in Latin America. As part of an epidemiological study, MSM were recruited through Respondent Driven Sampling in the metropolitan area of Buenos Aires, Argentina and answered a computerized behavioral survey. From the total of 500 MSM enrolled, a sub-sample of 233 aged 18-25 was analyzed. The sample was concentrated among lower socioeconomic strata, and only 16% identified as gay. Nearly half reported male, female, and transvestite sexual partners. Reported substance use was widespread ranging from 61% for marijuana to 20% for pasta base (cocaine sulfate). Seventy percent of the sample had never been tested for HIV infection; 3% tested positive for HIV and 8% for syphilis during the study.

RESUMO

Men who have sex with men and transgender women are hard-to-reach populations for research. Social media-based tools may overcome certain barriers in accessing these groups and are being tested in an ongoing study exploring HIV home-test kit use to reduce risk behavior. We analyzed pre-screening responses about how volunteers learned about the study (n = 896) and demographic data from eligible participants who came for an initial study visit (n = 216) to determine the strengths and weaknesses of recruitment strategies. Social media-based strategies resulted in the highest number of individuals screened (n = 444, 26% eligible). Dating sites/apps reached large numbers of eligible participants. White-Hispanics and African-Americans were more likely to be recruited through personal contacts; community events successfully reached Hispanic volunteers. Incorporating recruitment queries into pre-screening forms can help modify recruitment strategies for greater efficacy and efficiency. Findings suggest that recruitment strategies need to be tailored to reach specific target populations.

RESUMO

Self-testing has untapped potential as a strategy to improve access to HIV testing and to increase testing frequency. User acceptability of self-administered oral swab HIV tests is consistently high in both hypothetical and actual-use studies. We explored preferences for oral versus fingerprick HIV self-tests among men who have sex with men with a high risk profile. Participants indicated greater likelihood of using an oral swab over a blood-based test, notwithstanding lower price or quicker results from the latter. However, the likelihood of using an HIV fingerprick test substantially increased if it also offered information on other sexually transmitted infections.

RESUMO

Este artículo resume resultados publicados del proyecto LINKS. Un to-tal de 500 hombres que tienen sexo con hombres se incluyeron en un estudio de factores asociados a la infección por VIH, utilizando la meto-dología de Muestreo Dirigido por los Participantes (Respondent Driven Sampling, RDS, en inglés). El 24,5 % se identificó como homosexual, 36,2 % como bisexual, 21,9 % como heterosexual y 17,4 % como "otro". El 33 % de los participantes reportó haber tenido relaciones sexuales con hombres, mujeres y mujeres trans durante los 2 meses previos. La prevalencia de VIH, hepatitis B y sífilis fue de 17,3 %, 22,9 % y 20,5 %, respectivamente. Los participantes que sólo reportaron parejas sexua-les masculinas tuvieron prevalencias significativamente mayores. Más de dos tercios reportaron coito anal o vaginal sin protección durante los últimos dos meses. El 52 % nunca se había realizado el diagnóstico de VIH. El 25 % informó consumo ex-cesivo de alcohol y 34 % poli-consumo de drogas du-rante los dos meses previos. El 18 % de participantes reportó una experiencia sexual antes de los 13 años con una pareja al menos cuatro años mayor de edad. La aceptabilidad de los microbicidas y de la prueba casera del VIH fue alta

RESUMO

HIV self tests (HIVST) have the potential to increase testing among young adults. However, little is known about high-risk young adults' perception of the HIVST as a risk reduction tool and how they would use the HIVST in their everyday lives. Our study sought to examine these factors. Twenty-one ethnically diverse participants (ages 18-24) used the HIVST at our study site, completed surveys, and underwent an in-depth interview. Descriptive statistics were used to analyze the survey responses, and interview data were coded using constructs from the information-motivation-behavioral skills model. Information deficits included: how to use the HIVST and the "window period" for sero-conversion. Motivations supporting HIVST use included: not needing to visit the clinic, fast results, easy access, and use in non-monogamous relationships. Behavioral skills discussed included: coping with a positive test, handling partner violence after a positive test, and accessing HIV services. These findings can inform the use of the HIVST for improving HIV testing rates and reducing HIV risk behavior.

RESUMO

The purpose of this study was to understand high-risk young adults' use of the rapid human immunodeficiency virus (HIV) self-test. The highest rate of new HIV infections occurs in people between 15 and 24 years. Improving identification of young people infected with HIV is a critical public health priority. The first rapid HIV self-testing kit was approved in the US in 2012. Despite the product's promise, its use by untrained young adults is not well-understood. We conducted a mixed methods study using surveys, a think-aloud protocol, observations, and in-depth interviews. A systematic checklist was developed to assess participants' use of the test. A total of 21 racial and/or ethnic minority young adults aged 18-24 participated in this study. Analysis of our interview data was guided by the theory of reasoned action (TRA). Participants completed the initial procedures of the test with a mean time of 8:36 min (range of 2:04'-16:33'). On a 14-point checklist, participants had a mean score of 10.8 (SD 2.26, range 3-14). In the qualitative analysis of the participants' interviews, guided by the theoretical constructs of the TRA, the following themes emerged: "Did I use it correctly?", "Can I trust the results?" (attitude); "How will my partner react?!", "What will people think?" (subjective norm); "Quick, easy and blood free," and "Avoids the hassle of dealing with the healthcare system" (behavioral intention). This study provided evidence of the usefulness of the test perceived by young adults, especially in light of their concerns about lack of privacy in medical settings. Since many participants did not follow all of the instructions while using the test, it is not evident that young adults can correctly use the HIV self-test. Development of instructions manuals that are understandable and guide proper use of medical devices is a great need, especially in the context of home testing technology.

RESUMO

Pretendeu-se com a pesquisa realizada estudar e comparar padrões de testagem em relação ao VIH; resultados do teste para o VIH; e comportamentos sexuais preventivos de homens homo, hetero e bissexuais. Os dados foram recolhidos através de um questionário on-line. A amostra foi constituída por 732 participantes com idade média de 32,2 anos, dos quais 53,7% identificaram-se como homossexual/gay; 27,4%, como heterossexual; e 18,3%, como bissexual, refletindo a divulgação privilegiada do estudo junto a organizações de lésbicas, gays, bissexuais e transgênero (LGBT). Nunca tinham realizado o teste para o VIH 26,6% dos participantes; 7,2% indicaram ser portadores do HIV. Homens gays apresentaram níveis significativamente mais elevados de testagem para o VIH e de soropositividade, quando comparados com os restantes. No geral, verificou-se ainda que homens gays indicaram ter mais comportamentos preventivos. Todos os grupos estudados apresentaram padrões comportamentais específicos e diferenciados em relação ao VIH. Conclui-se que são de grande importância intervenções comportamentais desenhadas à medida das necessidades dos diferentes grupos estudados, em particular junto aos homens heterossexuais e gays.


The purpose of this study was to analyse and compare gay, heterosexual and bisexual men's HIV testing patterns, HIV test results, and sexual preventive behaviours. Data were collected through an online survey. The study's sample included 732 participants who met the selection criteria. Average age of participants was 32.2 years; 53.7% self-identified as gay, 27.4% as heterosexual, and 18.3% as bisexual. This distribution reflects the fact that the study was mostly publicized using LGBT networks. A total of 26.6% had never tested for HIV; 7.2% said they were HIV-positive. Gay men had significantly higher levels of HIV testing as well as rates of HIV infection when compared with the other groups. Overall, gay men displayed a larger variety of prevention strategies. All the groups under study showed specific and differentiated behavioural profiles with regard to HIV. We conclude that more efficient and tailored campaigns need to be developed to address each group's specific HIV prevention needs, in particular heterosexual and gay men's.

RESUMO

Qualitative studies of the sexual risk practices of Portuguese men who have sex with men (MSM) are scarce, as have been campaigns to target this group despite high HIV infection rates. This study investigates the concepts and practices of safer sex of a group of 36 Portuguese self-identified gay men (age: x = 34.4, SD = 9.1) who have met sexual partners online; two identified as HIV positive. Thematic analysis of interviews showed that our participants were aware of HIV transmission risks and tended to protect themselves in most sexual practices. Oral sex and steady relationships, however, did not always include safer practices. Participants tended to rely on indirect sources of information when assessing their partners’ HIV status, such as their physical characteristics or the information available in online profiles. Contrasting HIV positive and negative men’s sexual expectations and practices indicated that communication shortcomings might be putting some at risk. Findings suggest that safe sex is a relational practice which can only be understood and addressed within the context in which it occurs.


São escassos os estudos qualitativos sobre as práticas sexuais de risco de homens portugueses que fazem sexo com homens (HSH), assim como têm sido as campanhas dirigidas a este grupo, apesar das elevadas taxas de infecção por HIV entre HSH em Portugal. Este estudo investiga os conceitos e práticas de sexo seguro de um grupo de 36 HSH portugueses que encontraram parceiros sexuais na Internet (idade: x = 34,4, DP = 9,1). A análise temática das entrevistas mostrou que os participantes estavam cientes dos riscos de transmissão do HIV e tendiam a se proteger na maioria das práticas sexuais. Porém, sexo oral e relacionamentos estáveis nem sempre incluíam práticas seguras. Os entrevistados tendiam a confiar em fontes indiretas de informação para avaliar o estatuto HIV de seus parceiros, como o seu aspecto físico ou as informações disponíveis em perfis online. Verificaram-se ainda falhas de comunicação que podem estar colocando alguns em risco. Os resultados sugerem que o sexo seguro é uma prática relacional que deverá ser entendida e prevenida em função dos contextos em que ocorre.


Los estudios cualitativos sobre la práctica sexual de riesgo entre hombres portugueses que tienen sexo con hombres (HSH) son escasos, también las campañas preventivas dedicadas a este grupo, a pesar del alto índice de infección de VIH. Este estudio investiga conceptos y prácticas de sexo más seguras de un grupo de 36 HSH portugueses (edad: x = 34,4; DP = 9,1) que hubieran conocido parejas por Internet para mantener relaciones sexuales. El análisis temático de las entrevistas muestra que los participantes eran conscientes de los riesgos de transmisión del VIH y que tendieron a protegerse en la mayoría de las prácticas sexuales. Sin embargo, el sexo oral y las relaciones estables no implicaron prácticas más seguras siempre. Los participantes tendían a confiar en fuentes indirectas de información a la hora de evaluar el estado del VIH de sus parejas (e.g. aspecto físico; información disponible en perfiles de Internet).Una comunicación defectuosa puede poner a algunos en riesgo. Los resultados sugieren que el sexo seguro es una práctica relacional que necesita ser entendida e intervenida dentro de su contexto.

RESUMO

Adolescents and young adults are the fastest growing age group of human immunodeficiency virus (HIV) positive individuals in the US, and many who are infected do not know their HIV status. The HIV home test has the potential to help curb the HIV epidemic by improving detection of persons living with HIV and enabling them to seek follow-up care but it has not yet been evaluated in adolescents. Analogous to the home pregnancy test, which was met with much resistance and only successfully marketed during a time of social change, the HIV home test has been met with resistance since its FDA approval. This commentary summarizes the need to systematically evaluate positive and untoward/unanticipated effects of HIV home testing, particularly in young adults. The overall incidence of HIV has been declining in the US, yet it continues to grow at alarming rates for adolescents and young adults [1]. Almost 40 % of new HIV infections in the US are in this age group [2]. Further, many HIV infected adolescents and young adults are unaware of their infection. Nationwide, only 22.6 % of sexually active high school students have ever been tested for HIV [3]. While advances in drug regimens have transformed HIV into a chronic disease, infected individuals need to be identified and subsequently engaged in care [4].

RESUMO

This study explores the sexual behavior of 27 men who have sex with men (MSM) who regularly engage in unprotected anal intercourse (UAI), in the context of HIV home test (HT) use with potential sex partners. Participants were given 16 HT kits to use over 3 months. Among 40 sexual occasions following HIV-negative HT results, there were 25 UAI occasions (16 based on not typically using condoms and nine on HT results), 15 occasions in which condoms were used, and three in which sex did not occur. In the seven occasions where a potential partner received HIV-positive HT results, the sexual encounter ended. Almost all participants encountered potential partners who refused HT. Over half of these participants ended sexual encounters when HT was refused, perceiving these partners as HIV-positive or too high risk. Some participants reported that HT use heightened their awareness of HIV risk and their commitment to reducing it.
