RESUMO

Mpox, previously known as monkeypox, is caused by an Orthopoxvirus related to the variola virus that causes smallpox. Prior to 2022, mpox was considered a zoonotic disease endemic to central and west Africa. Since May 2022, more than 86,000 cases of mpox from 110 countries have been identified across the world, predominantly in men who have sex with men, most often acquired through close physical contact or during sexual activity. The classical clinical presentation of mpox is a prodrome including fever, lethargy, and lymphadenopathy followed by a characteristic vesiculopustular rash. The recent 2022 outbreak included novel presentations of mpox with a predominance of anogenital lesions, mucosal lesions, and other features such as anorectal pain, proctitis, oropharyngeal lesions, tonsillitis, and multiphasic skin lesions. We describe the demographics and clinical spectrum of classical and novel mpox, outlining the potential complications and management.

RESUMO

BACKGROUND: Little is known about penile high-risk HPV among MSM in low-and-middle income countries. We aimed to determine the incidence, clearance and persistence of penile hrHPV among Rwandan MSM. METHODS: We enrolled 350 MSM (345 with valid HPV results), aged ≥18 years, at each visit (6-12 months apart), we collected penile PreservCyt specimens and blood for HPV and HIV testing, socio-demographic and behavioral variables. HPV testing was performed using the Ampfire assay. Penile hrHPV incidence and clearance/1,000 person-months of follow-up (PMF), prevalent- and incident-persistence were computed and compared by HIV status. RESULTS: The mean age was 27.7 ± 6.7 years and 19.4% were living with HIV. Penile hrHPV incidence was 34.8 (95% CI: 29.1, 41.8)/1,000 PMF. HPV16 (11.7, CI 9.26, 14.9) and HPV59 (6.1, CI 4.52, 8.39) had the highest incidence rates. Prevalent- and incident-persistence were 47.5% and 46.6%, respectively. HPV66 (33.3%), HPV52 (30.8%) and HPV16 (29.2%) had the highest prevalent-persistence and HPV33 (53.8%), HPV31 (46.7%) and HPV16 (42.6%) the highest incident-persistence. No differences were found by HIV status except for HPV45 (higher in MSM with HIV). CONCLUSION: We found high incidence and prevalent/incident-persistence of penile hrHPV among Rwandan MSM. This highlights the importance of preventive strategies for HPV-associated anogenital cancers.

RESUMO

BACKGROUND: Neisseria gonorrheae and Chlamydia trachomatis are associated with mucosal inflammation and human immunodeficiency virus 1 (HIV-1) transmission. We assessed levels of inflammatory cytokines in men who have sex with men (MSM) with and without rectal gonorrhea and/or chlamydia in Lima, Peru. METHODS: We screened 605 MSM reporting condomless receptive anal intercourse for rectal N. gonorrheae/C. trachomatis using nucleic acid testing. We identified 101 cases of gonorrhea and/or chlamydia and randomly selected 50 N. gonorrheae/C. trachomatis positive cases and matched 52 negative controls. We measured levels of IL-1ß, IL-6, IL-8, and TNF-α in rectal secretions. Tests for HIV-1, rectal N. gonorrheae/C. trachomatis, and mucosal cytokines were repeated after 3 and 6 months. Cytokine levels in cases and uninfected controls were compared using Wilcoxon rank-sum tests and linear regression. RESULTS: MSM with gonorrhea/chlamydia had elevated levels of all cytokines in rectal mucosa compared with matched controls (all P values <.001). Following antibiotic treatment there were no significant differences in cytokine levels at 3- or 6-month follow-up evaluations (all P values >.05). DISCUSSION: Rectal gonorrhea/chlamydia infection is associated with transient mucosal inflammation and cytokine recruitment. Our data provide proof of concept for rectal sexually transmitted infection screening as an HIV prevention strategy for MSM. Clinical Trials Registration. NCT03010020.

RESUMO

BACKGROUND: Routine sexually transmitted infection and human immunodeficiency virus (STI/HIV) testing and HIV pre-exposure prophylaxis (PrEP) use are recommended for men who have sex with men (MSM) at increased risk of HIV. METHODS: Using Healthverity, a large administrative dataset in the United States, we assessed STI/HIV testing, chlamydia and gonorrhea positivity by specimen type, and HIV PrEP use among MSM and men who have sex with men and women (MSMW) at their first visits (index date) for those at increased risk of HIV and STIs from 2019 through 2022. RESULTS: Among 81,716 MSM and MSMW aged 15-64 years at their index date visit, STI testing rates were 57.9% for chlamydia, 58.1% for gonorrhea, and 52.2% for syphilis testing, respectively; 55.5%, 30.9%, and 18.1% had HIV testing, HIV PrEP use, and PrEP initiation, respectively, among the patients who did not have HIV. Of patients with chlamydia and gonorrhea testing, 48% were tested from the genital site only and 25% from three anatomic sites (rectal, pharyngeal, and urogenital). Chlamydia and gonorrhea positivity was 9.8% for chlamydia rectal infection, 7.3% for gonorrhea rectal infection, and 5.3% for gonorrhea pharyngeal infection. CONCLUSION: Our results present current medical services provided during initial clinic visits for MSM and MSMW in private outpatient settings. Our study suggests that the assessment of STI/HIV testing is periodically needed due to the high prevalence of infection, and efforts to promote HIV PrEP for MSM and MSMW in private settings are urgently needed.

RESUMO

Pasteurella bettyae is a gram-negative bacillus sporadically involved in human infections; its main reservoirs are cats and dogs. A recent publication suggests the possibility of sexual transmission leading to genital infections in men who have sex with men. We report 9 cases in France of genital infection among this population.

RESUMO

In 2022, concurrent outbreaks of hepatitis A, invasive meningococcal disease (IMD), and mpox were identified in Florida, USA, primarily among men who have sex with men. The hepatitis A outbreak (153 cases) was associated with hepatitis A virus genotype IA. The IMD outbreak (44 cases) was associated with Neisseria meningitidis serogroup C, sequence type 11, clonal complex 11. The mpox outbreak in Florida (2,845 cases) was part of a global epidemic. The hepatitis A and IMD outbreaks were concentrated in Central Florida and peaked during March--June, whereas mpox cases were more heavily concentrated in South Florida and had peak incidence in August. HIV infection was more common (52%) among mpox cases than among hepatitis A (21%) or IMD (34%) cases. Where feasible, vaccination against hepatitis A, meningococcal disease, and mpox should be encouraged among at-risk groups and offered along with program services that target those groups.

RESUMO

We estimated the incubation period for mpox during an outbreak in Pereira, Colombia, using data from 11 confirmed cases. Mean incubation period was 7.1 (95% CI 4.9-9.9) days, consistent with previous outbreaks. Accurately estimating the incubation period provides insights into transmission dynamics, informing public health interventions and surveillance strategies.

RESUMO

Here, strongly orientation-dependent lateral photoconductivity of a CdSe monolayer colloidal quantum wells (CQWs) possessing short-chain ligands is reported. A controlled liquid-air self-assembly technique is utilized to deliberately engineer the alignments of CQWs into either face-down (FO) or edge-up (EO) orientation on the substrate as opposed to randomly oriented (RO) CQWs prepared by spin-coating. Adapting planar configuration metal-semiconductor-metal (MSM) photodetectors, it is found that lateral conductivity spans ≈2 orders of magnitude depending on the orientation of CQWs in the film in the case of utilizing short ligands. The long native ligands of oleic acid (OA) are exchanged with short-chain ligands of 2-ethylhexane-1-thiol (EHT) to reduce the inter-platelet distance, which significantly improved the photoresponsivity from 4.16, 0.58, and 4.79&#x000A0;mA&#x000A0;W-1 to 528.7, 6.17, and 94.2 mA W-1, for the MSM devices prepared with RO, FO, and EO, before and after ligands exchange, respectively. Such CQW orientation control profoundly impacts the photodetector performance also in terms of the detection speed (0.061 s/0.074 s for the FO, 0.048 s/0.060 s for the EO compared to 0.10 s/0.16 s for the RO, for the rise and decay time constants, respectively) and the detectivity (1.7 × 1010, 2.3 × 1011, and 7.5 × 1011 Jones for the FO, EO, and RO devices, respectively) which can be further tailored for the desired optoelectronic device applications. Attributed to charge transportation in colloidal films being proportional to the number of hopping steps, these findings indicate that the solution-processed orientation of CQWs provides the ability to tune the photoconductivity of CQWs with short ligands as another degree of freedom to exploit and engineer their absorptive devices.

RESUMO

OBJECTIVES: To identify sexual/sex-associated risk factors for hepatitis C transmission among men who have sex with men (MSM) and visualise behavioural trajectories from 2019 to 2021. METHODS: We linked a behavioural survey to a hepatitis C cohort study (NoCo), established in 2019 across six German HIV/hepatitis C virus (HCV) treatment centres, and performed a case-control analysis. Cases were MSM with recent HCV infection, and controls were matched for HIV status (model 1) or proportions of sexual partners with HIV (model 2). We conducted conditional univariable and multivariable regression analyses. RESULTS: In all, 197 cases and 314 controls completed the baseline questionnaire and could be matched with clinical data. For regression models, we restricted cases to those with HCV diagnosed since 2018 (N = 100). Factors independently associated with case status included sex-associated rectal bleeding, shared fisting lubricant, anal douching, chemsex, intravenous and intracavernosal injections, with population-attributable fractions of 88% (model 1) and 85% (model 2). These factors remained stable over time among cases, while sexual partner numbers and group sex decreased during COVID-19 measures. CONCLUSIONS: Sexual/sex-associated practices leading to blood exposure are key factors in HCV transmission in MSM. Public health interventions should emphasize the importance of blood safety in sexual encounters. Micro-elimination efforts were temporarily aided by reduced opportunities for sexual encounters during the COVID-19 pandemic.

RESUMO

BACKGROUND: HIV-infected persons demonstrate notable disturbances in their intestinal microbiota; however, the impact of intestinal microbiota on HIV susceptibility in men who have sex with men (MSM), as well as the effects of HIV and antiretroviral therapy (ART) on their gut microbiota, remains under active study. Thus, our research focuses on clarifying the distinctions in intestinal microbiota composition among uninfected MSM and non-MSM healthy controls, investigating the alterations in early-stage intestinal microbial communities following HIV infection, and assessing how ART affects the intestinal microbiota. METHODS: This study enrolled four participant groups: uninfected MSM, Recent HIV-1 infection (RHI) MSM, MSM on ART, and non-MSM healthy controls, with 30 individuals in each group. We utilized 16S ribosomal DNA (16S rDNA) amplicon sequencing to analyze fecal microbiota and employed Luminex multiplex assays to measure plasma markers for microbial translocation (LBP, sCD14) and the inflammatory marker CRP. FINDINGS: Comparing uninfected MSM to non-MSM healthy controls, no substantial variances were observed in α and ß diversity. Uninfected MSM had higher average relative abundances of Bacteroidetes, Prevotella, and Alloprevotella, while Bacteroides, Firmicutes, and Faecalibacterium had lower average relative abundances. MSM on ART had lower intestinal microbiota diversity than RHI MSM and uninfected MSM. In MSM on ART, Megasphaera and Fusobacterium increased, while Faecalibacterium and Roseburia decreased at genus level. Additionally, treatment with a non-nucleoside reverse transcriptase inhibitor (NNRTI) led to significant alterations in intestinal microbiota diversity and composition compared to RHI MSM. The random forest model showed that HIV infection biomarkers effectively distinguished between newly diagnosed HIV-infected MSM and HIV-negative MSM, with an ROC AUC of 76.24% (95% CI: 61.17-91.31%). CONCLUSIONS: MSM showed early intestinal microbiota imbalances after new HIV infection. MSM on ART experienced worsened dysbiosis, indicating a combined effect of HIV and ART. NNRTI-based treatment notably changed intestinal microbiota, suggesting a potential direct impact of NNRTI drugs on intestinal microbiota.

RESUMO

BACKGROUND: In May 2023, the Food and Drug Administration (FDA) released final guidance for blood donor eligibility that recommended the elimination of 3-month deferral for men who have sex with men (MSM) and the related deferral for women who have sex with MSM. In its place, FDA introduced an individual risk assessment policy of asking all presenting blood donors, regardless of sex or gender, if they have had a new partner or more than one sexual partner in the last 3 months and deferring those who also report anal sex (penile-anal intercourse) during this period. We modeled the possible impact of this policy on the US blood donor base. STUDY DESIGN AND METHODS: We developed a computational model to estimate the percentage of blood donors who would be deferred under a policy of individual HIV risk assessment. The model incorporated demographic information about donors and national survey data on HIV risk behaviors and included age and sex distributions and dependencies. RESULTS: Our model estimates that approximately 1.2% of US blood donors would be deferred under the individual HIV risk assessment paradigm. DISCUSSION: The model predicts a relatively minor effect of replacing the time-based deferral for MSM with individual risk-based deferral for sexual behavior. As US blood centers implement this new policy, the effect may be mitigated by donor gains, which warrant further study. The new policy is unlikely to adversely affect the availability of blood and blood components.

RESUMO

BACKGROUND: In Australia, a man cannot donate blood if he has had sex with another man within the past 3 months. However, this policy has been criticized as being discriminatory as it does not consider lower risk subgroups, and led to calls for modifications to the policy that more accurately distinguish risk among gay, bisexual, and other men who have sex with men (GBM). STUDY DESIGN AND METHODS: We used data from a nationally representative survey to estimate the proportion of GBM aged 18-74 years old who would be eligible to donate under current criteria and other scenarios. RESULTS: Among the 5178 survey participants, 155 (3.0%) were classified as GBM based on survey responses, Among the GBM, 40.2% (95% CI 28.0%-53.7%) were eligible to donate based on current criteria, and 21.0% (95% CI 14.5%-29.5%) were ineligible due to the 3 months deferral alone. Eligibility among GBM, all men, and the population increased as criteria were removed. Under the new Australian plasma donation criteria, 73.6% (95% CI 64.4%-81.1%) of GBM, 68.4% (95% CI 65.5%-71.2%) of all men, and 60.8% (95% CI 58.8%-62.8%) of the full population were estimated to be eligible. Only 16.1% (95% CI 8.6%-28.1%) of GBM knew that the male-to-male sex deferral period is 3 months. DISCUSSION: Changing the deferral criteria and sexual risk evaluation would lead to a higher proportion of GBM being eligible to donate blood. Knowledge of the current GBM deferral period is very low. Improved education about the current criteria and any future changes are required to improve blood donation rates.

RESUMO

Oral HPV infection is the main risk factor for the development of oropharyngeal carcinoma. Men who have sex with men (MSM), especially if living with HIV (PLWH), are at increased risk of infection and consequently of cancer development. Aim of this study is to evaluate the impact of nonavalent vaccine on oral HPV infection in a cohort of MSM and transgender women (TGW). This prospective study included all MSM and TGW who started nonavalent HPV vaccination from May 2019 to September 2021. Oral rinse was collected before each vaccine administration and after six months of follow up. Descriptive statistics were used. Kaplan Meier probability curves and Cox regression models for HPV acquisition and clearance were calculated. The analysis included 211 individuals (202 MSM and 9 TGW). PLWH were 138 (65.4%). Baseline oral rinse was positive in 30 subjects (14.2%). Positivity rate did not change over time (p = 0.742), even when restricting the analysis only to high-risk genotypes (p = 0.575) and to genotypes covered by vaccine (p = 0.894). The risk to acquire HPV infection was 12.8% at one year and 33.4% at two years after vaccination. The probability to clear the infection was 67.6% at one year and 87.9% at two years. HIV infection had no impact on vaccine efficacy. Age above 45 years was the only factor associated to HPV acquisition (aHR 4.06, 95% CI 1.03-15.98, p = 0.045). Prevalence of oral HPV infection was higher in PLWH, but HIV had no impact on viral clearance or acquisition after vaccination.

RESUMO

Among men who have sex with men (MSM), those who also engage in the exchange of sex for money, drugs, shelter or other material goods (i.e., male sex workers-MSWs) have been found to have higher rates of condomless anal sex (CAS), HIV, and STIs than MSM who do not engage in exchange sex. To gain a better understanding of the factors that influence MSWs' engagement in CAS with male clients, we analyzed qualitative interview data from a diverse sample of 141 MSWs from 8 U.S. cities who met clients primarily through hookup or dating apps/websites and who reported having condomless anal sex with at least one of their exchange sex partners in the prior three months. While high client demand and financial incentives were the most frequently mentioned reasons for engaging in CAS with clients, other factors including drug and alcohol use, attraction to the client, the heat of the moment, concerns about sexual performance, and reliance on pre-exposure prophylaxis (PrEP) were also important. Participants who engaged in CAS generally felt that due to client characteristics or mitigating steps they had taken themselves, their chance of acquiring HIV/STIs was acceptably low. Hookup or dating apps/websites have provided an additional and increasingly popular venue for exchange sex to be arranged. These platforms also offer an opportunity for HIV/STI prevention through interventions and tailored messages delivered through these venues that address the motivations, misconceptions and/or situational factors that may lead to CAS.


RESUMEN: Entre los hombres que tienen relaciones sexuales con hombres (HSH), se ha encontrado que aquellos que también participan en el intercambio de sexo por dinero, drogas, vivienda u otros bienes materiales (es decir, hombres trabajadores sexuales-HTS) tienen tasas más altas de sexo anal sin condón (SASC), VIH y ETS que los HSH que no participan en relaciones sexuales de intercambio. Para obtener una mejor comprensión de los factores que influyen en la participación de los HTS en SASC con clientes masculinos, analizamos los datos de entrevistas cualitativas de una muestra diversa de 141 HTS de 8 ciudades de EE. UU. que conocieron a los clientes principalmente a través de aplicaciones/sitios web de conexión o citas y que informaron haber tenido sexo anal sin condón con al menos una de sus parejas sexuales de intercambio en los tres meses anteriores. Mientras la alta demanda de los clientes y los incentivos financieros fueron las razones mencionadas con mayor frecuencia para participar en SASC con los clientes, otros factores como el uso de drogas y alcohol, la atracción hacia el cliente, la seducción del momento, las preocupaciones sobre el desempeño sexual y la dependencia de la profilaxis preexposición (PrEP) también fueron importantes. Los participantes que tomaron parte en SASC generalmente sintieron que debido a las características del cliente o a los pasos de mitigación que habían tomado ellos mismos, su probabilidad de contraer VIH / ETS era aceptablemente baja. Las aplicaciones/sitios web de conexión o citas han proporcionado un lugar adicional y cada vez más popular para organizar el intercambio de sexo. Estas plataformas también ofrecen una oportunidad para la prevención del VIH/ETS a través de intervenciones y mensajes personalizados que se transmiten a través de estos lugares y que abordan las motivaciones, los conceptos erróneos y/o los factores situacionales que pueden conducir a SASC.

RESUMO

Minority stressors have been linked to HIV risk behaviors among gay, bisexual, queer, and other men who have sex with men (MSM). Committed partnerships are a key context for new HIV infections and coping with minority stress among MSM, but very little work has tested the minority stress-HIV risk link among male couples, and little is known about how processes within one's relationship may exacerbate or buffer this association. The present study examined links between minority stress (i.e., internalized stigma, microaggressions) and HIV transmission risk behaviors (i.e., condomless anal sex with outside partners, breaks in relationship agreements) among male couples, as well as relationship-based moderators (i.e., social support, dyadic coping) of these associations. An analytic sample of male couples from a large cohort study (analytic N = 410 individuals, 205 dyads) completed self-report measures of minority stress, relationship-based moderators, and HIV transmission risk behaviors which were submitted to moderated actor-partner interdependence models (APIMs). In many cases, coping with stress with one's partner buffered the minority stress-HIV transmission link risk. However, findings also suggested situations in which partners may overburden one another with coping, thus exacerbating HIV-related risk behaviors.

RESUMO

HIV stigma is a social determinant of health that can influence multiple health outcomes, including adherence to antiretroviral therapy (ART), engagement in HIV care, and viral suppression levels in people with HIV (PWH). In Peru, where the HIV epidemic is concentrated in men who have sex with men (MSM) and transgender women (TGW), stigma may play an important role in healthcare engagement. To understand the relationship between stigma and two outcome variables, ART adherence and engagement in HIV care in 400 MSM and TGW, we assessed factors from the Behavioral Model for Vulnerable Populations at two HIV clinics that tailor services for sexual and gender minorities. While some predisposing, need, and enabling resource factors were associated with optimal (≥ 90%) ART adherence or engagement in HIV care, none of the stigma subscales were correlated, suggesting that when LGBTQ-affirming care is provided to MSM/TGW, stigma may not influence HIV-related outcomes.


RESUMEN: El estigma hacia el VIH es un determinante social de la salud que puede influir en múltiples desenlaces, incluyendo la adherencia a la terapia antirretroviral (TAR), el compromiso con la atención del VIH y los niveles de supresión viral en personas viviendo con VIH (PVV). En el Perú, donde la epidemia del VIH se concentra en hombres que tienen sexo con hombres (HSH) y mujeres transgénero (MT), el estigma puede desempeñar un papel importante en el compromiso con la atención médica. Para comprender la relación entre el estigma y dos variables de resultado, la adherencia al TAR y el compromiso con la atención del VIH en 400 HSH y MT, evaluamos factores del Modelo de Comportamiento para Poblaciones Vulnerables en dos clínicas de VIH que adaptan sus servicios para minorías sexuales y de género. Si bien algunos factores predisponentes, de necesidad y de recursos habilitantes se asociaron con una adherencia óptima (≥ 90%) al TAR o al compromiso con la atención del VIH, ninguna de las sub-escalas de estigma estuvieron correlacionadas, sugiriendo que cuando se brinda atención que afirma a la comunidad LGBTQ a HSH/MT, el estigma puede no influir en los desenlaces relacionados con el VIH.

RESUMO

Men who have sex with men (MSM) with history of childhood sexual abuse (CSA) are at high risk for HIV acquisition. One reason is posttraumatic responses compromise ability to accurately appraise risk for danger/vulnerability. Health behavior change models and related interventions assume risk perception can be changed in an enduring manner. Given paucity of studies examining how risk perception changes or sustains over time post-intervention, this underlying assumption is not confirmed. Among this particularly high-risk group who struggle with perceiving risk due to trauma-related cognitions, it may be accuracy of risk perception is fluid. The study primarily aimed to examine accuracy of HIV risk perception over time post-HIV prevention behavioral intervention. Leveraging data from a larger RCT, N = 190 MSM in Boston, MA and Miami, FL USA completed a psychosocial baseline assessment, an intervention aimed to increase awareness of personal HIV risk level, then four follow-up assessments three months apart for a year. Linear mixed effect models were used to examine the degree to which accuracy of HIV risk perception (vs. traditional construct of risk perception with no information about accuracy) predicts sex risk behavior over time delineated by between-person (trait level) and within-person (state level) effects. Majority (92%) of participants fluctuated in HIV risk accuracy over time post-intervention. Within-person risk accuracy (one's accuracy at any given timepoint) predicted sex risk behavior (condomless sex not protected by adherent PrEP) over time, but not between-person (one's average of accuracy). Findings have implications for intervention and counseling related to specific HIV prevention strategies.

RESUMO

Black and African American men who have sex with men (Black MSM) experience the greatest proportion of new HIV infections in the United States. To address this challenge, a better understanding of the HIV environment riskscape including both risk and resilience factors is warranted among Black MSM. Research indicates that stress is associated with increased HIV sexual risk behaviors. Further, behavioral factors such as serosorting and community level factors including social support and community connection are resilience factors that protect against risk behaviors. The present study examines whether everyday stress is associated with HIV sexual risk behavior, as well as the role of risk and resilience factors among 125 Black MSM recruited in the Real Talk study. The Real Talk project examined the relationships between resilience, HIV risk behaviors, and HIV prevention strategy among a sample of Black MSM. Using generalized estimating equations, our results indicate a positive association between everyday stress and engaging in condomless anal intercourse only after adjusting for risk, resilience, and correlate variables. Similarly, having multiple sex partners and using substances during sex also show positive associations with condomless anal intercourse. Resilience factors of engaging in serosorting and being connected to both the Black and gay communities were negatively associated with condomless anal intercourse. Future prevention research and programming should focus on both risk and resilience factors to mitigate new HIV infections among Black MSM.

RESUMO

Dating apps are now used by the majority of MSM to meet sexual and romantic partners. While research has demonstrated an association between app use and greater number of sex partners and STIs, dating apps also pose an opportunity for intervention. By advocating for new and improved sexual health features on dating apps, Building Healthy Online Communities (BHOC) aims to increase communication about sexual health on the apps. As a follow-up to our previous paper assessing the uptake of sexual health-related profile options on dating apps through Emory's annual survey of 10,000 MSM in the US, BHOC and Emory partnered to explore the change in uptake over time, again through their annual survey. Among survey participants in 2021, 85% reported using dating apps to meet a partner in the past year, and among this group, 93% reported awareness of sexual health features, up from 77% in 2018 (p < 0.0001). 71% of app users who were aware of features in 2021 reported using one or more sexual health feature, up from 61% in 2018 (p < 0.0001). BHOC will continue to advocate for increased uptake of these features, especially among subgroups with lower levels of uptake.

RESUMO

Sexual and gender minorities (SGM) using online venues in India are usually not reached by government HIV interventions, remaining an understudied yet important population. We investigated sociodemographic characteristics, sexual behaviours along with familiarity, knowledge, and correlated factors around perceived accuracy of the Undetectable = Untransmittable (U = U) slogan. Grindr users in India completed an online, cross-sectional survey in May-June 2022. We included individuals ≥ 18 years old who reported sex with men (excluding those who were born female and or identified as cis-gender female). Associations with perceived U = U accuracy were estimated using adjusted prevalence odds ratios (aPOR) with 95% confidence intervals (95% CI). The survey was completed by 3,126 eligible participants. The median age was 28 years and most participants lived in urban areas and had graduate or postgraduate education. HIV prevalence was 3.1%. Only 14% reported familiarity with the U = U slogan and after an explanation was provided, 25% perceived it as completely accurate. This was associated with knowing their HIV status (HIV Negative aPOR 1.37 [95%CI 1.1, 1.71], HIV Positive aPOR 3.39 [95%CI 2.11, 5.46]), having heard of PrEP (aPOR1.58 [95%CI 1.29,1.92]) or have used PrEP (aPOR1.56 [95%CI 1.15, 2.12]) along with use of party drugs (aPOR1.51 [95%CI 1.0 2.10]), being in touch with NGOs (aPOR 1.61 [95%CI 1.27, 2.02], p < .001) and having attended LGBTQIA + events (aPOR1.38 [95%CI 1.1, 1.73]). SGMs in India had low familiarity and low perceived accuracy around U = U. Education about U = U and innovating new strategies to reach this hidden population could reduce stigma around HIV in India.


RESUMEN: Las minorías sexuales y de género (MSG) que utilizan sitios en línea en la India, generalmente no son alcanzadas por el gobierno a través de sus intervenciones contra el VIH aunque siguen siendo una población importante, pero poco estudiada. Se investigaron las características sociodemográficas, el comportamiento sexual y, adicionalmente, la familiaridad, el conocimiento y la percepción de exactitud sobre el eslogan Indetectable = Intransmisible (I = I). Los usuarios indios de Grindr completaron una encuesta transversal en línea entre mayo y junio del 2022. Se incluyeron a personas ≥ 18 años que informaron haber tenido relaciones sexuales con hombres (se excluyeron aquellas asignadas como mujer al nacer y que se identificaron como mujeres cisgénero). Las asociaciones con la precisión percibida de I = I se estimaron con razones de probabilidad de prevalencia ajustadas (aPR) con intervalos de confianza a 95% (IC 95%). En total, 3,126 participantes elegibles completaron la encuesta. La mediana de edad fue de 28 años, la mayoría vivían en áreas urbanas y eran graduados o posgraduados. La prevalencia del VIH fue de 3.1%. Solo 14% informó que conocía el eslogan I = I, pero incrementó a 25% después de que se proporcionó una explicación y lo percibieron como completamente exacto. Esto se asoció con conocer su estado serológico (aPR VIH negativo = 1.37 [IC 95%: 1.1, 1.71]; aPR VIH positivo = 3.39 [IC 95%: 2.11, 5.46]), tener conocimiento de la profilaxis preexposición (PrEP) (aPR = 1.58 [IC 95%: 1.29,1.92]), haber usado la PrEP (aPR = 1.56 [IC 95% 1.15, 2.12]), usado drogas con fines recreativos (aPR = 1.51 [IC 95%: 1.0, 2.10]), estar en contacto con las ONG (aPOR 1.61 [95%CI 1.27, 2.02], p < .001) y haber asistido a eventos LGBTIQA+ (aPR = 1.38 [IC 95%: 1.0, 2.10]). Las MSG en India tuvieron poco conocimiento y poca percepción de exactitud sobre el eslogan I = I. La educación sobre I = I y otras estrategias innovadoras de prevención para el VIH en esta población podría ayudar a reducir el estigma en torno a esta enfermedad en la India.
