Vaccine effectiveness against anal HPV among men who have sex with men aged 18-45 years attending sexual health clinics in three United States cities, 2018-2023.

BACKGROUND: We assessed human papillomavirus (HPV) vaccine effectiveness (VE) against anal HPV among men who have sex with men (MSM) in 2018-2023. METHODS: Residual anal specimens from MSM without HIV ages 18-45 years were tested for HPV. We calculated adjusted prevalence ratios (aPR) and 95% confidence intervals (CI) for associations between vaccination (≥1 dose) and quadrivalent vaccine (4vHPV)-type prevalence adjusting for city, race/ethnicity, and non-vaccine-type HPV prevalence, stratified by age group (18-26, 27-45). VE was calculated as (1-aPR)x100. RESULTS: Among 2802 persons aged 18-26, 4vHPV-type prevalence was lower in those vaccinated at age <18 (aPR=0.13, CI: 0.08-0.22, VE=87%) and those vaccinated ≥2 years before specimen collection (aPR=0.52, CI: 0.42-0.64, VE=48%), compared with unvaccinated persons. Among 3548 persons aged 27-45, 4vHPV-type prevalence was lower in those vaccinated at ages 18-26 (aPR=0.68, CI: 0.57-0.82, VE=32%) and those vaccinated ≥2 years before specimen collection (aPR=0.66, CI: 0.57-0.77, VE=33%), compared with unvaccinated persons. While we observed no VE in persons vaccinated at age >26 overall, 4vHPV-type prevalence was lower in the subgroup vaccinated ≥2 years before specimen collection (aPR=0.71, CI: 0.56-0.89, VE=29%). CONCLUSIONS: We found high VE against anal 4vHPV-type prevalence among MSM aged 18-26 who were vaccinated at age <18. Lower VE was observed among MSM ages 27-45 who were vaccinated at age 18-26 or ≥2 years before specimen collection. While ideally vaccination should be given at younger ages, vaccination can prevent some future infections in this population.

What We (Don't) Know about the Infectious Disease Burden Among Youth Experiencing Homelessness in the United States and Canada.

Youth experiencing homelessness (YEH) and sexual and gender minority (SGM) YEH may be at increased risk for infectious diseases due to living arrangements, risk behaviors, and barriers to healthcare access that are dissimilar to those of housed youth and older adults experiencing homelessness. To better understand infectious diseases among YEH populations, we synthesized findings from 12 peer-reviewed articles published between 2012 to 2020 which enumerated YEH or SGM YEH infectious disease burden in locations across the U.S. or Canada. Pathogens presented in the studies were limited to sexually transmitted infections (STIs) and bloodborne infections (BBI). Only three studies enumerated infectious diseases among SGM YEH. There was a dearth of comparison data by housing status (ex., sheltered versus unsheltered youth), SGM identity, or other relevant counterfactual groups in the identified studies. We also introduce three publicly available, national-level surveillance datasets from the U.S. or Canada that quantify certain STIs, BBIs, and tuberculosis among YEH, which may be used for future disease burden assessments. Our review calls for more comprehensive YEH-centered research that includes multimodal data collection and timely disease surveillance to improve estimates of infectious diseases among this vulnerable population.

Satisfaction with care, general health, and mental health among sexual and gender minority cancer survivors: Results of the OUT National Cancer Survey.

BACKGROUND: Few studies have attempted to characterize the cancer care experiences and outcomes of sexual and gender minority (SGM) patients with cancer, despite indications that this population experiences disparities across the cancer continuum. The current study used descriptive and exploratory methods to assess factors related to SGM cancer patients' satisfaction with cancer care and self-reported physical and mental health. METHODS: The authors designed a cross-sectional self-report online survey and recruited 3750 SGM cancer patient participants (mixed cancers; 85.6% White; 57% gay, 24% lesbian, 6.7% bisexual, and 6.2% transgender/gender nonbinary) using social media posts, partner organizations, and paid advertisements. They analyzed data using descriptive approaches and exploratory multivariate logistic regression models. RESULTS: Overall, 70.6% of participants reported feeling satisfied with the cancer care they received, 70% rated their physical health as very good or excellent, and 46% reported experiencing less than 5 days of poor mental health in the last month. In models including all participants, complete cases, and Black, Indigenous, and people of color (BIPOC), satisfaction with care was consistently associated with receiving treatment in an SGM welcoming environment. Physical health was consistently associated with having strong social support after cancer. Mental health was consistently associated with feeling safe disclosing SGM identities. CONCLUSIONS: SGM cancer patients treated in SGM-welcoming environments were over six times more likely to be satisfied with the care they received than those treated in nonwelcoming environments; this and other modifiable factors could be the target of further study and intervention.

Culturally-sensitive and Inclusive IBD Care.

As the prevalence of inflammatory bowel disease (IBD) increases within historically disadvantaged communities, it is imperative to better understand how intersectionality-defined as the complex, cumulative way in which the effects of multiple forms of discrimination (such as racism, sexism, and classism) - intersect and social determinants of health influence the patient's experiences within the medical system when navigating their disease. Culturally-sensitive care is characterized by the ability to deliver patient-centered care that recognizes how the intersectionality of an individual's identities impacts their disease journey. An intentional consideration and sensitivity to this impact play important roles in providing an inclusive and welcoming space for historically disadvantaged individuals living with IBD and will help address health inequity in IBD. Cultural competence implies mastery of care that understands and respects values and beliefs across cultures, while cultural humility involves recognizing the complexity of cultural identity and engaging in an ongoing learning process from individual patient experiences. Heightening our patient care goals from cultural competence to cultural sensitivity allows healthcare professionals and the systems in which they practice to lead with cultural humility as they adopt a more inclusive and humble perspective when caring for patient groups with a diverse array of identities and cultures and to avoid maintaining the status quo of implicit and explicit biases that impede the delivery of quality IBD care. In this article, we will review the literature on IBD care in historically disadvantaged communities, address culturally-sensitive care, and propose a framework to incorporating cultural humility in IBD practices and research.

Awareness of the causal association between human papillomavirus and anal cancer among US adults.

PURPOSE: The incidence of anal cancer is on the rise in the US, especially among high-risk groups. This study examined the prevalence and determinants of awareness of the causal relationship between HPV and anal cancer among US adults. METHODS: Study data was obtained from the 2017 to 2020 iterations of the Health Information National Trends Survey. The prevalence of awareness that HPV causes anal cancer was estimated among HINTS respondents who were aware of HPV in general. Survey weights were used to provide estimates representative of the adult US population. Multivariable logistic regressions were used to examine the associations between awareness that HPV causes anal cancer and cancer-related behaviors/perceptions and sociodemographic characteristics of respondents. RESULTS: Two thousand six hundred and eighty four (27.2%) of the study population were aware that HPV caused anal cancer. Those of gay sexual orientation were more aware than heterosexuals [OR 2.27; 95% CI (1.24, 4.14)]. Compared to respondents with a high school diploma or less, individuals with some college education [OR 1.38; 95% CI (1.03, 1.85)] and those with at least a college degree [OR 1.52; 95% CI (1.17, 1.98)] were more likely to be aware. Participants who had positive cancer information seeking behavior were more aware of the HPV-anal cancer link compared to those who did not [OR 1.57; 95% CI (1.30, 1.89)]. CONCLUSION: Population-level awareness that HPV causes anal cancer remains critically low in the US. Sexual orientation, level of education and cancer information seeking behavior are associated with increased awareness of the causal relationship between HPV and anal cancer. Efforts should be directed toward addressing the awareness gap among individuals with lower education levels and promoting curiosity-driven information seeking behaviors.

Transgender persons' view on previous fertility decision-making and current infertility: a qualitative study.

STUDY QUESTION: How do adult transgender and gender diverse (TGD) people, who are infertile due to prior gender-affirming treatment, view their current infertility and their reproductive decisions made in the past? SUMMARY ANSWER: In a time where sterilization was mandatory, transgender adolescents prioritized gender-affirming treatment over their future fertility and would make the same choice today despite emotional challenges related to infertility experienced by some. WHAT IS KNOWN ALREADY: Under transgender law in the Netherlands, sterilization was required for legal gender recognition until 2014, resulting in permanent infertility. The long-term consequences of this iatrogenic infertility in transgender adolescents who have now reached adulthood remain underexplored. STUDY DESIGN, SIZE, DURATION: Qualitative study design based on 21 in-depth one-on-one semi-structured interviews. PARTICIPANTS/MATERIALS, SETTING, METHODS: TGD people in a stage of life where family planning may be a current topic were eligible for participation. They all received gender-affirming treatment in adolescence prior to the legislation change in 2014. A purposeful sampling technique was used from participants of another ongoing study. Eleven people assigned female at birth and ten people assigned male at birth were included. Interview transcripts were thematically analysed using a modified version of Braun and Clarke's six steps theory. MAIN RESULTS AND THE ROLE OF CHANCE: Six main themes were generated: (i) personal considerations regarding fertility and fertility preservation in the past; (ii) external considerations regarding fertility and fertility preservation in the past; (iii) current vision on past considerations and decisions; (iv) Current experiences and coping with infertility; (v) future family building; (vi) advice regarding fertility and fertility preservation decision-making. LIMITATIONS, REASONS FOR CAUTION: Selection, recall, and choice supportive bias may play a role in interpreting our results. WIDER IMPLICATIONS OF THE FINDINGS: This study highlights the importance of tailored counselling and comprehensive information on fertility preservation for transgender individuals, especially adolescents, undergoing gender-affirming treatment.

Describing the effect of COVID-19 on sexual and healthcare-seeking behaviours of men who have sex with men in three counties in Kenya: a cross-sectional study.

BACKGROUND: While the COVID-19 pandemic disrupted HIV preventative services in sub-Saharan Africa, little is known about the specific impacts the pandemic has had on men who have sex with men (MSM) in Kenya. METHODS: Data were from an HIV self-testing intervention implemented in Kisumu, Mombasa and Kiambu counties in Kenya. Baseline data collection took place from May to July 2019, and endline in August-October 2020, coinciding with the lifting of some COVID-19 mitigation measures. Using endline data, this study characterised the impact the pandemic had on participants' risk behaviours, experience of violence and behaviours related to HIV. Logistic regression was used to understand factors related to changes in risk behaviours and experiences of violence; adjusted AORs (AORs) and 95% CIs are reported. RESULTS: Median age was 24 years (IQR: 21-27). Most respondents (93.9%) reported no change or a decrease in the number of sexual partners (median number of male sexual partners: 2, IQR: 2-4). Some participants reported an increase in alcohol (10%) and drug (16%) consumption, while 40% and 28% reported decreases in alcohol and drug consumption, respectively. Approximately 3% and 10% reported an increase in violence from intimate partners and police/authorities, respectively. Compared with those with primary education, those with post-secondary education were 60% less likely to report an increase in the number of male sexual partners per week (AOR: 0.4, 95% CI: 0.2 to 0.9), while those who were HIV positive were at twofold the odds of reporting an increase or sustained levels of violence from intimate partners (AOR: 2.0, 95% CI: 1.1 to 4.0). CONCLUSION: The results of this study demonstrate heterogeneity in participants' access to preventative HIV and clinical care services in Kenya after the onset of the COVID-19 epidemic. These results indicate the importance of responding to specific needs of MSM and adapting programmes during times of crisis.

Reach of GetCheckedOnline among gay, bisexual, transgender and queer men and Two-Spirit people and correlates of use 5 years after program launch in British Columbia, Canada.

OBJECTIVES: Understanding who uses internet-based sexually transmitted and blood-borne infection (STBBI) services can inform programme implementation, particularly among those most impacted by STBBIs, including gender and sexual minority (GSM) men. GetCheckedOnline, an internet-based STBBI testing service in British Columbia, Canada, launched in 2014. Our objectives were to assess reach, identify factors associated with use of GetCheckedOnline 5 years into implementation and describe reasons for using and not using GetCheckedOnline among GSM men. METHODS: The Sex Now 2019 Survey was an online, cross-sectional survey of GSM men in Canada administered from November 2019 to February 2020. Participants were asked a subset of questions related to use of GetCheckedOnline. Multivariable binary logistic regression modelling was used to estimate associations between correlates and use of GetCheckedOnline. RESULTS: Of 431 British Columbia (BC) participants aware of GetCheckedOnline, 27.6% had tested using the service. Lower odds of having used GetCheckedOnline were found among participants with non-white race/ethnicity (adjusted OR (aOR)=0.41 (95% CI 0.21 to 0.74)) and those living with HIV (aOR=0.23 (95% CI 0.05 to 0.76)). Those who usually tested at a walk-in clinic, relative to a sexual health clinic, had greater odds of using GetCheckedOnline (aOR=3.91 (95% CI 1.36 to 11.61)). The most commonly reported reason for using and not using GetCheckedOnline was convenience (78%) and only accessing the website to see how the service worked (48%), respectively. CONCLUSION: Over a quarter of GSM men in BC aware of GetCheckedOnline had used it. Findings demonstrate the importance of social/structural factors related to use of GetCheckedOnline. Service promotion strategies could highlight its convenience and privacy benefits to enhance uptake.

Early adopters of doxycycline as post-exposure prophylaxis to prevent bacterial sexually transmitted infections in a real-world clinical setting.

OBJECTIVES: Doxycycline as post-exposure prophylaxis (DoxyPEP) is a novel prevention approach which has demonstrated efficacy in preventing bacterial sexually transmitted infections (STIs) in men who have sex with men (MSM) and transgender women (TGW) including people who are living with HIV and those on HIV pre-exposure prophylaxis (PrEP). We evaluated patient knowledge and interest in DoxyPEP, as well as early adopters of its use. METHODS: In 2023, patients presenting for HIV and STI services at a primary care and sexual health clinic were asked about DoxyPEP knowledge, interest and use. Bivariate and multivariate analyses were used to evaluate demographics and behaviours associated with these outcomes. RESULTS: A total of n=421 people presented for care. Of these, 314 were MSM/TGW. Fifteen percent were Black/African-American, and 21% were Hispanic/Latino. A total of 50% of MSM/TGW had heard of DoxyPEP, 49% were interested and 18% reported prior DoxyPEP use. Having a history of STI infection ever (adjusted OR (aOR) 5.95, 95% CI 2.69 to 13.13) and in the past 12 months (aOR 2.99, 95% CI 1.56 to 5.72) were both associated with DoxyPEP use. Individuals who had ever used HIV PrEP had nearly three times the odds of ever taking DoxyPEP (aOR 2.88, 95% CI 1.56 to 5.30). There was no association between the use of DoxyPEP and race, ethnicity or HIV status. CONCLUSIONS: Among MSM and TGW, there is already significant awareness, interest and use of DoxyPEP to prevent bacterial STIs. Public health efforts should focus on improving access and delivery of this STI prevention intervention to MSM and TGW.

Awareness of chronic hepatitis B and C in men who have sex with men in Belgium: epidemiological survey and on-site screening.

OBJECTIVES: To eliminate hepatitis B and C virus (HBV/HCV) as a public health threat by 2030, the WHO focuses on screening key populations, including men who have sex with men (MSM).This study aims to assess HBV and HCV knowledge and awareness and HCV prevalence in MSM in Belgium. METHODS: First, a questionnaire was designed to assess MSM's knowledge of HBV and HCV infection (disease process, vaccination, treatment and transmission routes). This questionnaire was conducted online, and by means of a tablet-based face-to-face questionnaire at the Antwerp and Belgian Pride. Second, HCV and HIV prevalence data were collected during outreach projects and office screening for sexually transmitted infections (STIs) organised by Sensoa and Exaequo, a Flemish and Walloon sexual health organisation. RESULTS: 300 MSM completed the questionnaire (median age 36 years; 7.7% HIV+). Mean overall survey scores were low (HBV: 41.1%; HCV: 39.8%). Few participants identified all transmission routes correctly (HBV: 15%; HCV 1%).The degree of education was significantly correlated with HBV knowledge and showed a trend towards correlation with HCV knowledge. HCV knowledge was significantly correlated with high-risk sexual behaviour.The prevalence of HCV and HIV was 0.3% and 1.0%, respectively, in MSM attending commercial gay venues and 0% and 1.9% in MSM attending office STI screening. CONCLUSIONS: Knowledge of HBV and HCV infection in MSM is poor. More awareness campaigns are needed, focusing on frequent HCV risk factors (group sex, chemsex, receptive fisting, and sharing of anal toys and anal douching devices), especially targeting low-educated MSM. HBV vaccination of MSM requires continued attention.The prevalence of HCV and HIV was remarkably low in commercial gay venues and may be higher in older MSM or in subcultures where risk factors coexist (eg, chemsex). The cost-effectiveness of internet-based approaches with subsequent at-home testing needs to be evaluated in the future.

Acceptability of a rectal microbicide douche for HIV prevention: a mixed-methods analysis of a first-in-human formulation pilot study.

OBJECTIVES: DREAM-01 was an open label, dose-escalation and variable osmolarity study to identify a tenofovir HIV-prevention douche/enema that could achieve protective colon tissue cell concentrations and high acceptability. To assess impact on sexual enjoyment, iso-osmolar and hypo-osmolar placebo douches were provided for at-home use before receptive anal sex (RAS). METHODS: Eighteen HIV-uninfected men who have RAS were administered three tenofovir douches at the research clinic: Product A, an iso-osmolar dose; Product B, an iso-osmolar escalation dose; and Product C, a hypo-osmolar escalation dose. Following Products A and C, participants were given a saline douche of matching osmolarity to use at home before RAS. Participants reported acceptability via a computer-assisted self-interview and in-depth interview in this mixed-methods study. RESULTS: All three products were rated acceptable by 17 (95%) of the participants. A majority (94%) would be likely or very likely to use any of the three products before RAS. Of those who used the saline douches before RAS and then rated their sexual enjoyment, most reported that their sexual enjoyment was not affected. Interview data revealed that participants found the product easy to incorporate into their regular routine, but would prefer to use more liquid for cleansing. CONCLUSIONS: These findings indicate that the hypo-osmolar Product C, which also provides the most rapid delivery of tenofovir for HIV prevention, is acceptable for future safety trials and that our sample reports high likelihood of using a rectal microbicide douche for HIV prevention. Our findings support continued pursuit of a tenofovir rectal microbicide douche. TRIAL REGISTRATION NUMBER: NCT02750540.

Cross-sectional associations of gender identity and sexual orientation, with co-occurrence and clustering of health-related behaviours among British adolescents: Millennium cohort study.

PURPOSE: We examined whether gender identity and sexual orientation were associated with seven health-related behaviours, and with co-occurrence and clustering of these behaviours among British adolescents. METHODS: Millennium Cohort Study (age 17 wave) provided data on the exposures, gender identity (male, female, genderqueer) and sexual orientation (heterosexual, bisexual, gay or lesbian, or other), and seven self-reported health-related behaviours (binge drinking, drug use, no consumption of breakfast, no consumption of fruits or vegetables, physical inactivity, poor sleep, and smoking or vaping). Poisson regressions examined associations between the exposures and single behaviours (reporting prevalence ratios (PRs)); and multinomial logistic regressions were used for behavioural cumulative co-occurrence score (reporting PRs). Cluster patterns were identified using Ward's agglomerative hierarchical cluster analysis while associations with cluster membership were performed using logistic regressions (reporting odds ratios (ORs)). RESULTS: Our sample included 6022 adolescents (55.4% female, 1.5% genderqueer, 11.6% non-heterosexual). Adolescents who identified as genderqueer had the highest prevalence of not eating breakfast (PR: 60.5% [95%CI 48.4-71.4]) and poor sleep (68.7% [95%CI 55.6-79.3]). Those who identified as bisexual had a higher PR of co-occurring behaviours (2.46 [95%CI 1.39-4.27]). Among the three clusters identified (1: Multiple risk behaviours; 2: Physical inactivity and binge drinking; 3: Poor diet and physical inactivity), adolescents who identified as genderqueer or other sexual orientation showed the highest prevalence in cluster 3. CONCLUSION: Gender and sexual minority British adolescents showed a higher prevalence of risky health-related behaviours, and higher risk of co-occurring behaviours. Physical inactivity and poor diet behaviours commonly clustered together for these groups.

Self-Reported PrEP Use and Risk of Bacterial STIs Among Ontarian Men Who Are Gay or Bisexual or Have Sex With Men.

PURPOSE: HIV pre-exposure prophylaxis (PrEP) may increase rates of bacterial sexually transmitted infections (STIs) among gay, bisexual, and other men who have sex with men (GBM) through risk compensation (eg, an increase in condomless sex or number of partners); however, longitudinal studies exploring the time-dependent nature of PrEP uptake and bacterial STIs are limited. We used marginal structural models to estimate the effect of PrEP uptake on STI incidence. METHODS: We analyzed data from the iCruise study, an online longitudinal study of 535 Ontarian GBM from July 2017 to April 2018, to estimate the effects of PrEP uptake on incidence of self-reported bacterial STIs (chlamydia, gonorrhea, and syphilis) collected with 12 weekly diaries. The incidence rate was calculated as the number of infections per 100 person-months, with evaluation of the STIs overall and individually. We used marginal structural models to account for time-varying confounding and quantitative bias analysis to evaluate the sensitivity of estimates to nondifferential outcome misclassification. RESULTS: Participating GBM were followed up for a total of 1,623.5 person-months. Overall, 70 participants (13.1%) took PrEP during the study period. Relative to no uptake, PrEP uptake was associated with an increased incidence rate of gonorrhea (incidence rate ratio = 4.00; 95% CI, 1.67-9.58), but not of chlamydia or syphilis, and not of any bacterial STI overall. Accounting for misclassification, the median incidence rate ratio for gonorrhea was 2.36 (95% simulation interval, 1.08-5.06). CONCLUSIONS: We observed an increased incidence rate of gonorrhea associated with PrEP uptake among Ontarian GBM that was robust to misclassification. Although our findings support current guidelines for integrating gonorrhea screening with PrEP services, additional research should consider the long-term impact of PrEP among this population.Annals Early Access article.

The City Clinic Cohort Study: Hepatitis B, HTLV-III/LAV, and CDC AIDS Project 24.

Anticipating the availability of a safe vaccine, scientists at the Center for Disease Control (CDC) planned for a multicenter study of the prevalence, incidence, and efficacy of an experimental vaccine for hepatitis B in 1977, conducted the study among homosexual male volunteers in five collaborating sexually transmitted infection (STI) clinics in the United States from April 1978 through 1980, and concluded that the candidate vaccine was highly efficacious in preventing infections with the hepatitis B virus. Then something completely unexpected and portentous happened. Some successfully vaccinated as well as other homosexual and bisexual men began to show signs and symptoms of a rare cancer, Kaposi's sarcoma, and opportunistic infections typically associated with severe immunodeficiency. As early as October 1983, members of the Hepatitis B study cohort in San Francisco were invited to return to the city STI clinic for further examinations, testing, and confidential interviews about their sexual and other practices. CDC AIDS Project 24 was designed to help describe the natural history of AIDS, define risk factors, and predict future trends. It produced some of the earliest and most convincing scientific evidence about the seriousness and extent of the AIDS epidemic among homosexual and bisexual men in the United States. How the City Clinic Cohort Study came about and evolved is the focus of this commentary.

RESUMEN: Anticipando la disponibilidad de una vacuna segura, los científicos del Centro para el Control de Enfermedades (CDC) planearon un estudio multicéntrico sobre la prevalencia, incidencia y eficacia de una vacuna experimental contra la hepatitis B en 1977; realizaron el estudio entre voluntarios varones homosexuales en cinco colaboraron con clínicas de infecciones de transmisión sexual (ITS) en los Estados Unidos desde abril de 1978 hasta 1980, y concluyeron que la vacuna candidata era muy eficaz para prevenir infecciones por el virus de la hepatitis B. Entonces sucedió algo completamente inesperado y portentoso. Algunos hombres vacunados con éxito, así como otros hombres homosexuales y bisexuales, comenzaron a mostrar signos y síntomas de un cáncer poco común, el sarcoma de Kaposi, e infecciones oportunistas típicamente asociadas con una inmunodeficiencia grave. Ya en octubre de 1983, se invitó a los miembros de la cohorte del estudio de la hepatitis B en San Francisco a regresar a la clínica de ITS de la ciudad para realizar más exámenes, pruebas y entrevistas confidenciales sobre sus prácticas sexuales y de otro tipo. El Proyecto 24 del CDC sobre SIDA fue diseñado para ayudar a describir la historia natural del SIDA, definir factores de riesgo y predecir tendencias futuras. Produjo algunas de las primeras y más convincentes pruebas científicas sobre la gravedad y el alcance de la epidemia de SIDA entre los hombres homosexuales y bisexuales en los Estados Unidos. El tema central de este comentario es cómo surgió y evolucionó el estudio de cohorte de City Clinic.

Perceived Accuracy Around Undetectable = Untransmitable Among Sexual and Gender Minorities Using Smartphones in India.

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.

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

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

RESUMEN: Indetectable = Intransmisible (I = I) comunica que las personas que viven con VIH (PVVIH) y reciben tratamiento antirretroviral (TAR) no transmitirán el VIH a sus parejas sexuales. En este estudio, describimos la concienciación sobre I = I entre las minorías sexuales y de género (MSG) de Brasil, México y Perú según el estado de VIH autoreportado (PVVIH, negativo, desconocido) durante 2021 utilizando una encuesta en línea. Se estimaron dos modelos mediante regresión de Poisson para cada grupo: Modelo A, que incluyó factores sociodemográficos (país, sexo, edad, raza, educación e ingresos) y Modelo B, que incluyó recibir TAR (para PVVIH) o comportamiento de riesgo, uso de PrEP y percepción de riesgo (para VIH negativo o desconocido). Se incluyó 21,590 encuestados (Brasil: 61%, México: 30%, Perú: 9%). Entre aquellos negativos para VIH (74%) y con estado desconocido (12%), el 13% utilizó alguna vez PrEP. Entre las PVVIH (13%), el 93% reportó recibir actualmente TAR. La concienciación de I = I fue del 89% tanto en Brasil como en México, superior al 64% de Perú. La concienciación de I = I fue mayor entre PVVIH (96%) que entre los VIH-negativos (88%) y los VIH-desconocidos (70%). En los modelos multivariados, las PVVIH con menor educación eran menos conscientes de I = I, mientras que los que tomaban TAR eran más conscientes. Entre los VIH-negativos, las personas no cisgéneros, con menores ingresos y con menor educación eran menos consciente de I = I, mientras que los que tenían experiencia usando PrEP eran más conscientes. En conclusión, la concienciación sobre I = I varió según el estado serológico de VIH, las características sociodemográficas y el comportamiento de riesgo. El concepto de I = I debe difundirse a través de estrategias educativas, incluyendo un enfoque en MSG para combatir el estigma del VIH.

Racial HIV Testing Inequalities in Adolescent Men who have Sex with Men and Transgender Women in Three Brazilian Cities.

Many barriers to human immunodeficiency virus (HIV) testing among Black people exist. This study analysed the association between race/skin colour and lifetime HIV testing among adolescent men who have sex with men (AMSM) and transgender women (ATGW) in three Brazilian cities. This cross-sectional study was nested within the PrEP1519 cohort, a multicentre study of AMSM and ATGW aged 15-19 years in Belo Horizonte, Salvador, and São Paulo, Brazil. The outcome variable was the lifetime HIV testing (no or yes). The main exposure variable was self-reported race/skin colour as White and a unique Black group (composed of Pardo-mixed colour and Black, according to the Brazilian classification). Descriptive statistics and bivariate and multiple logistic regression analyses were conducted to estimate the adjusted odds ratios (ORs) and 95% confidence intervals (95% CIs) to determine the association between the main exposure and outcome, adjusted for covariates. White adolescents were tested more frequently than the unique Black group (64.0% vs. 53.7%, respectively; Ρ = 0.001). Multiple logistic regression analysis showed that the unique Black group of AMSM and ATGW had 26% (adjusted OR [aOR], 0.74; 95% CI, 0.55-0.98) and 38% (aOR, 0.62; 95% CI, 0.45-0.87) lower odds of being tested for HIV in a lifetime than Whites in model 1 and 2, respectively. Our findings highlight the role of racism in lifetime HIV testing among AMSM and ATGW. Therefore, an urgent need for advances exists in public policies to combat racism in Brazil.

RESUMEN: Existen numerosas barreras para la realización de las pruebas del virus de la inmunodeficiencia humana (VIH) entre la población negra. Este estudio analizó la asociación entre la raza/color de piel y haber realizado pruebas de VIH a lo largo de la vida entre hombres adolescentes que tienen sexo con hombres (AHSH) y mujeres transgénero (AMTG) en tres ciudades brasileñas. Este estudio transversal es parte de la cohorte PrEP1519, un estudio multicéntrico de AHSH y AMTG de 15 a 19 años en Belo Horizonte, Salvador y São Paulo, Brasil. La variable de resultado fue haber realizado la prueba del VIH a lo largo de la vida (no o sí). La variable de exposición principal fue la raza/color de piel autoinformada, categorizada como blanca y un grupo negro único (compuesto por color pardo/mixto y negro, según la clasificación brasileña). Se realizaron estadísticas descriptivas y análisis de regresión logística bivariada y multivariada para estimar los odds ratios (OR) ajustados y los intervalos de confianza del 95% (IC del 95%) con el fin de determinar la asociación entre la exposición principal y el resultado, ajustado por covariables. Los adolescentes blancos se hicieron la prueba del VIH con más frecuencia que el grupo negro único (64,0% frente a 53,7%, respectivamente; Ρ = 0,001). El análisis de regresión logística múltiple reveló que el grupo negro único de AHSH y AMTG tenía 26% (OR ajustado [aOR], 0,74; IC 95%, 0,55­0,98) y 38% (aOR, 0,62; IC 95%, 0,45­0,87) menores probabilidades de realizarse la prueba del VIH a lo largo de su vida que los blancos en los modelos 1 y 2, respectivamente. Nuestros hallazgos resaltan la influencia del racismo en la realización de pruebas de VIH a lo largo de la vida entre AHSH y AMTG. Por lo tanto, es urgente avanzar en la implementación de políticas públicas para combatir el racismo en Brasil.

Longitudinal Modeling of Bacterial Sexually Transmitted Infections Among Sexual Minority Men Living with HIV.

Bacterial sexually transmitted infections (BSTIs) are largely preventable, yet their rates remain high across the U.S., particularly among sexual minority men (SMM) living with HIV (LWH). We explored longitudinal factors associated with BSTI acquisition in a national online sample of SMM LWH with recent suboptimal adherence to antiretroviral therapy (ART) or virologic non-suppression, such as spread within sexual networks, drug use in a sexual context (chemsex), and mental health issues. Participants completed online surveys over 12 months as part of an eHealth intervention. Over 12 months, 30% of participants self-reported at least one BSTI, with 28-45% reporting recurrent infections in consecutive surveys. Using generalized estimating equations with a binomial distribution and an exchangeable correlation structure, we found that BSTI accumulation was associated with chemsex, a higher number of anal sex partners, participation in exchange sex, and depressive symptoms. To reduce the burden of BSTIs among SMM LWH, public health initiatives and clinical settings should adopt a comprehensive sexual health approach, addressing chemsex, exchange sex, and associated mental health conditions. Addressing these factors can mitigate BSTI recurrence and improve overall sexual health among SMM LWH.

Measurement Instruments Assessing Multi-Faceted Stigma Regarding Sexual and Gender Minorities: A Systematic Review of Psychometric Properties.

Stigma against sexual and gender minorities (SGM) populations has serious negative health effects for SGM populations. Despite the growing need for accurate stigma measurement in SGM, there are insufficient valid measurement instruments. Moreover, the lack of consistency in construct usage makes comparisons across studies particularly challenging. A critical review and comparative evaluation of the psychometric properties of the various stigma measures for SGM is necessary to advance our understanding regarding stigma measurement against/among SGMs. Based on the PRISMA (Preferred Reporting Items for Systematic Reviews and Meta-Analyses) guidelines, a comprehensive search was conducted in 4 bibliographic databases (MEDLINE, PsycINFO, CINAHL, and Web of Science) for empirical articles published from 2010 to 2022 that evaluated the psychometrics properties of measurement instruments assessing stigma against SGMs. The screening, extraction, and scoring of the psychometric properties and methodological quality of selected instruments were performed by following the established standards and COSMIN (Consensus-based Standards for the selection of health Measurement Instruments) checklist, respectively. Of the 2031 studies identified, 19 studies were included that reported psychometric properties of 17 measurement instruments. All instruments, except two, were developed for SGMs (n = 15/17). Most instruments included men who have sex with men (MSM) or gay men (n = 11/15), whereas less than half of the instruments assessed stigma among SGM women (n = 6/15). Internal consistency (Cronbach's alpha) and content validity was reported for all instruments (n = 17); construct and structural validity was also reported for majority of the instruments (n = 15 and 10, respectively). However, test-retest reliability and criterion validity was reported for very few instruments (n = 5 each). Based on the COSMIN checklist, we identified the most psychometrically and methodologically robust instruments for each of the five stigma types: combined stigma, enacted stigma, internalized stigma, intersectional stigma, and perceived stigma. For each stigma type, except anticipated stigma, at least one instrument demonstrated strong promise for use in empirical research; however, the selection of instrument depends on the target population and context of the study. Findings indicated a growing use of instruments assessing multiple stigma types. Future studies need to develop intersectional stigma instruments that account for the multiple and intersecting social identities of SGMs. Additionally, most existing instruments would benefit from further psychometric testing, especially on test-retest reliability, criterion validity, adaptability to different LGBTQIA + populations and cultures.

Social Network Characteristics Associated with More Frequent HIV and STI Prevention Conversations: The N2 Cohort Study in Chicago.

Black cisgender sexually minoritized men (SMM) and transgender women (TW) are subgroups at highest risk of HIV and sexually transmitted infections (STIs) in the US. We sought to identify factors facilitating continued conversations - social reinforcement - surrounding HIV/STI prevention among this subgroup. Participants were recruited in Chicago from 2018 to 2019 from community health spaces. Participants provided information about themselves (level 2) and ⩽5 confidants (level 1). We used multinomial multilevel modeling to identify associations with HIV/STI prevention conversation frequency. A total of 370 participants provided information on 987 confidants (mean = 2.6). We found significantly positive associations between having biweekly or more often HIV/STI prevention conversations and a confidant being a kin family member, older by 15 years or more, racially homophilous, and emotionally close. Future interventions should harness social networks by including components that consider racial homophily, respect for elders, and strong ties, in addition to applying kin family systems interventions approaches and decreasing stigma surrounding HIV/STIs.
