Increases in Awareness and Uptake of Dating Apps' Sexual Health Features Among US Men Who Have Sex with Men, 2018 to 2021.

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.

Reasons for Migration and Their Associations with HIV Risk and Prevention Among Cisgender Sexual Minority Men: A Latent Class Analysis.

The immigrant population in the United States (U.S.) is rapidly growing; yet there is limited knowledge about how reasons for migrating to the U.S. are associated with HIV prevention behaviors. Using data from the American Men's Internet Survey (2018-2020), we performed a Latent Class Analysis (LCA) to identify patterns in reasons for migration among cisgender gay, bisexual, and other sexual minority men (SMM) who born outside the U.S. We used multivariable logistic regression controlling for demographic characteristics to assess class associations with the following in the past 12 months: condomless anal sex (CAS), illicit drug use, marijuana use, HIV testing, and PrEP use. LCA identified six distinct patterns in reasons for migration among the sample (n = 1,657): (1) Family and friends (14%); (2) Financial (17%); (3) Personal freedom related to being gay (10%); (4) Pursuit of opportunities while living openly as SMM (12%); (5) Educational purposes (18%); (6) Not my decision (29%). While HIV testing (range = 57.6-65.4%) and PrEP use (range = 15.6-21.4%) did not vary by class (p > .05 for all), CAS and illicit drug use were significantly different (p < .05). SMM who migrated to pursue opportunities while living openly and whose reasons were not their decision had greater odds of CAS than SMM who migrated for educational purposes (aOR:1.72, 95% confidence interval [95%CI]:1.15-2.59; 1.57, 1.13-2.19, respectively). Reasons for migration among SMM were associated with behaviors that can increase HIV risk, but not testing or PrEP. Push and pull factors related to migration should be considered when developing behavioral HIV interventions for immigrant SMM.

RESUMEN: La población inmigrante en los Estados Unidos (EE. UU.) está creciendo rápidamente; sin embargo, hay un conocimiento limitado acerca de cómo las razones para migrar a los EE. UU. se asocian con comportamientos de prevención del VIH. Utilizando datos del American Men's Internet Survey (2018­2020), realizamos un Análisis de Clases Latentes (ACL) para identificar patrones en las razones de migración entre hombres cisgénero gays, bisexuales y otros hombres de minorías sexuales (HMS) que reportaron haber nacido fuera de los EE. UU. Utilizamos regresión logística multivariable controlando las características demográficas para evaluar las asociaciones de clases con los siguientes comportamientos en los últimos 12 meses: sexo anal sin condón (SAC), consumo de drogas ilícitas, uso de marihuana, prueba del VIH y uso de PrEP. El ACL identificó seis patrones distintos en las razones de migración en la muestra (n = 1,657): (1) Familia y amigos (14%); (2) Motivos financieros (17%); (3) Libertad personal relacionada con ser gay (10%); (4) Búsqueda de oportunidades mientras viven abiertamente como HMS (12%); (5) Propósitos educativos (18%); (6) No fue decisión propia (29%). Mientras que las pruebas del VIH (rango = 57.6­65.4%) y el uso de PrEP (rango = 15.6­21.4%) no variaron según la clase (p > .05 para todos), el SAC y el consumo de drogas ilícitas fueron significativamente diferentes (p < .05). Los HMS que emigraron para perseguir oportunidades mientras vivían abiertamente, y aquellos cuyas razones no fueron decisión propia, tuvieron mayores probabilidades de tener SAC que los HMS que emigraron con propósitos educativos (razón de probabilidades ajustada [aOR]: 1.72, intervalo de confianza del 95% [IC 95%]: 1.15­2.59; 1.57, 1.13­2.19, respectivamente). Las razones de migración a los EE. UU. entre los HMS estuvieron asociadas con comportamientos que pueden aumentar el riesgo de VIH, pero no con pruebas o PrEP. Los factores que impulsan y atraen relacionados con la migración deben considerarse al desarrollar intervenciones de prevención del VIH para HMS inmigrantes.

Behavior Change Among HIV-Negative Men Who Have Sex with Men Not Using PrEP in the United States.

This study measures changes in condomless anal sex (CAS) among HIV-negative men who have sex with men (MSM) who are not taking pre-exposure prophylaxis (PrEP). It considers the 2014-2019 cycles of the American Men's Internet Survey, a serial, cross-sectional web-based survey of US cisgender MSM aged ≥ 15 years, in which ~ 10% of each year's sample is drawn from the previous year. Among those surveyed for 2 years who remained HIV-negative and off PrEP, reports of having any CAS and of CAS partner number were compared across years. We disaggregated by partner HIV status, and considered demographic predictors. The overall population saw a significant 2.2 percentage-point (pp) increase in reports of any CAS year-over-year. Sub-populations with the largest year-on-year increases were 15-24-year-olds (5.0-pp) and Hispanic respondents (5.1-pp), with interaction (young Hispanic respondents = 12.8-pp). On the relative scale, these numbers correspond to 3.2%, 7.2%, 7.3% and 18.7%, respectively. Absolute increases were concentrated among partners reported as HIV-negative. Multivariable analyses for CAS initiation found effects concentrated among Hispanic and White youth and residents of fringe counties of large metropolitan areas. CAS partner number increases were similarly predicted by Hispanic identity and young age. Although condom use remains more common than PrEP use, increasing CAS among MSM not on PrEP suggests potential new HIV transmission pathways. Concentration of increases among 18-24-year-old MSM portends future increases in the proportion of newly diagnosed HIV that occur among youth. Concentration among young Hispanic MSM will likely expand existing disparities. Although reducing barriers to PrEP remains vital, condom promotion for MSM remains a key public health practice and appears to be missing key audiences. LGBTQ+-inclusive sex education is one avenue for enhancing these efforts.

Sexual behavior stigma and HIV/STI biospecimen self-collection among cisgender gay, bisexual, and other sexually minoritized men in the United States.

INTRODUCTION: Disparities in HIV and other sexually transmitted infections (STIs) persist among cisgender sexually minoritized men in the United States, driven in part by sexual behavior stigma, which is a barrier to clinic-based HIV/STI testing. HIV/STI biospecimen self-collection (HSBS) is a novel testing approach that mitigates stigma by allowing for some testing-related procedures to be conducted by oneself in one's home or any private location rather than a facility that requires interpersonal interactions and exposure to other members of the public. HSBS has demonstrated acceptability, feasibility, and effectiveness in testing uptake, but the extent to which stigma persists in HSBS and the quantification of stigma's role in HSBS is limited. METHODS: From 2019-2020, a nationwide sample of sexually minoritized men completed an online biobehavioral survey. Those who agreed to be recontacted (N = 4147) were invited to participate in HSBS; consented participants received self-collection kits that were laboratory-tested if completed. Sexual behavior stigma and HSBS associations were assessed with logistic regression. RESULTS: Mean age of participants was 35 years, 58% (2421/4147) were non-Hispanic white, 82% (3391/4147) were gay-identifying, 47% (1967/4147) had at least a college degree, and 56% (2342/4147) earned ≥ $40,000 annually; 27% (1112/4147) expressed HSBS interest, and 67% (689/1034) completed HSBS. HSBS interest and completion were less common among non-Hispanic Black sexually minoritized men and sexually minoritized men of lower socioeconomic status. Stigma from family and friends was significantly, negatively associated with HSBS interest (aOR = 0.72, 95% CI = 0.56, 0.93). Among those who had not tested for HIV/STIs in the past year, anticipated healthcare stigma was marginally, negatively associated with HSBS completion (aOR = 0.40, 95% CI = 0.15, 1.07). Among those who had never previously tested for HIV/STIs, anticipated healthcare stigma was significantly, negatively associated with HSBS interest (aOR = 0.32, 95% CI = 0.14, 0.72). CONCLUSIONS: Sexual behavior stigma persists as an HIV/STI testing barrier, even in the case of HSBS, limiting its utilization. Increasing HSBS among sexually minoritized men in the US necessitates stigma mitigation efforts that directly address equity in implementation.

Characterizing the Communication Networks of Spanish- and English-Speaking Latinx Sexual Minority Men and Their Roles in Pre-Exposure Prophylaxis Uptake.

While pre-exposure prophylaxis (PrEP) has demonstrated efficacy in preventing HIV transmission, disparities in access persist in the United States, especially among Hispanic/Latinx sexual minority men (SMM). Language barriers and differences in how Latinx SMM obtain information may impact access to PrEP and HIV prevention. This study used data from the 2021 American Men's Internet Survey (AMIS) to examine differences in communication networks and PrEP use among Latinx SMM by primary language (Spanish vs. English). We examined the associations between Latinx SMM's individual- and meso-level communication networks and PrEP-related outcomes using modified Poisson regression with robust variances. Spanish-speaking Latinx SMM in the study were less likely to test for HIV, be aware of PrEP, and use daily PrEP, compared to English-speaking participants. Sexuality disclosure to a healthcare provider was positively associated with PrEP uptake among all participants and predicted STI testing over the past 12 months among English-speaking Latinx SMM. Findings highlight disparities in PrEP awareness and uptake among Latinx SMM, especially among those whose primary language is Spanish. Addressing these disparities through targeted interventions, including improved communication with healthcare providers, may help facilitate PrEP access and use in this population.

Intersecting Sexual Behavior and Gender Identity Stigmas Among Transgender Women in the United States: Burden and Associations with Sexual Health.

In the United States, a context of multiple marginalization shapes sexual health disparities experienced by transgender women. Using data from 396 transgender women with negative or unknown HIV status, we performed exploratory factor analysis on responses to gender identity and sexual behavior stigma items and regressed sexual health outcomes on extracted factors via modified Poisson regression with robust variance estimation. Overall, 97.2% of participants endorsed ≥ 1 gender identity stigma; 67.2% endorsed ≥ 1 sexual behavior stigma; and 66.9% endorsed ≥ 1 of each. Extracted factors included gender-identity social stigma, reflecting experiences related to family, fearfulness in public, and verbal harassment (α = 0.68); gender-identity institutional stigma/violence, reflecting experiences related to healthcare, police interactions, and interpersonal violence (α = 0.73); and global sexual behavior stigma, reflecting experiences related to family, friends, and healthcare, as well as police interactions, fearfulness in public, verbal harassment, and interpersonal violence (α = 0.83). Gender-identity social stigma was significantly, positively associated with testing for HIV and testing for sexually transmitted infections. Gender-identity institutional stigma/violence and global sexual behavior stigma were both significantly, positively associated with condomless anal sex, sex work, testing for HIV, testing for sexually transmitted infections, and use of HIV pre-exposure prophylaxis. Stigma-mitigation remains critical to improve quality of life and sexual health for transgender women in the United States.

Examining Geographical Differences in the HIV Care Continuum Among Men Who Have Sex with Men in Mexico.

We analyzed data collected by the Encuesta de Sexo Entre Hombres study from 15,233 Mexican men who have sex with men (MSM) between May-July 2017 to examine differences in the HIV care continuum. Data were stratified into 6 geographical regions. Prevalence ratios assessed associations between region and care outcomes. Among participants never testing HIV positive (n = 13,583), 66.1% had ever been tested and 43.0% in the past year. Among HIV-positive persons (n = 1,650), 83.9% reported counseling post-diagnosis, 61.9% timely linkage to care, 42.4% timely CD4/viral load results, 38.2% timely access to antiretroviral therapy (ART), and 87.7% were currently on ART. The Ciudad de México /Estado de México region had significantly superior care continuum outcomes in ever and recent HIV testing, linkage to care, CD4/viral load results, and current ART use. Understanding geographical variations in HIV care for MSM in Mexico is one important step to inform efforts for ending HIV/AIDS by 2030 in Latin America.

RESUMEN: Analizamos los datos de 15,233 hombres mexicanos que tienen sexo con hombres (HSH) recopilados entre mayo y julio de 2017 por el estudio Encuesta de Sexo Entre Hombres para examinar las diferencias en el continuo de la atención del VIH. Los datos se estratificaron en seis regiones geográficas. Se utilizaron razones de prevalencia para evaluar las asociaciones entre la región y los resultados de la atención. Entre los participantes sin prueba de VIH positiva (n = 13 583), el 66.1% se había hecho la prueba alguna vez en su vida y el 43.0% en el último año. Entre las personas que refirieron pruebas de VIH positivas (n = 1 650), el 83.9% informó asesoramiento post-diagnóstico, el 61.9% vinculación oportuna a la atención, el 42.4% resultados oportunos de CD4/carga viral, el 38.2% acceso oportuno a la terapia antirretroviral (TAR) y el 87.7% continuaba en TAR. La región de la Ciudad de México/Estado de México tuvo resultados del continuo de la atención significativamente superiores en pruebas de VIH pasadas y recientes, vinculación con la atención, resultados de carga viral/CD4 y uso actual de TAR. Comprender las variaciones geográficas de la atención del VIH en HSH en México es un paso importante para informar los esfuerzos para poner fin a la epidemia de HIV/Sida para 2030 en Latinoamérica.

Effects of mode of transportation on PrEP persistence among urban men who have sex with men.

Little is known about the effect of travel-related factors, such as mode of transportation, on retention in PrEP care, or PrEP persistence. We used data from the 2020 American Men's Internet Survey and conducted multilevel logistic regression to estimate the association between mode of transportation used for healthcare access and PrEP persistence among urban gay, bisexual, and other men who have sex with men (MSM) in the U.S. MSM using public transportation were less likely to report PrEP persistence (aOR: 0.51; 95% CI: 0.28-0.95) than MSM using private transportation. There were no significant associations between PrEP persistence and using active transportation (aOR: 0.67; 95% CI: 0.35-1.29) or multimodal transportation (aOR: 0.85; 95% CI: 0.51-1.43) compared to using private transportation. Transportation-related interventions and policies are needed to address structural barriers to accessing PrEP services and to improve PrEP persistence in urban areas.

Patient sexuality disclosure experience and associations with clinical sexual health outcomes among HIV-negative men who have sex with men in Mexico.

Many men who have sex with men (MSM) do not disclose their sexuality to their healthcare provider, despite potential health benefits. Data from the 2017 Encuesta de Sexo Entre Hombres online survey of 13,277 HIV-negative or unknown status MSM in Mexico were used to explore MSM patients' sexuality disclosure experience on sexual health outcomes using multivariable Poisson models with robust variance estimation to estimate adjusted prevalence ratios (aPR). Sexual health outcomes included Hepatitis B (HepB) and human papillomavirus (HPV) vaccination, and lifetime and past year HIV testing. Overall, 53.9% (n/N) disclosed their sexuality to their healthcare provider, and of those 6.4%, 62.9%, and 30.7% reported a negative, neutral, or positive disclosure experience, respectively. In comparison to no disclosure, neutral and positive disclosure experiences were associated with HepB vaccination (aPR[95% Confidence Interval (95% CI)] = 1.17[1.09, 1.25], p < 0.001; aPR[95% CI] = 1.35[1.25, 1.46], p < 0.001, respectively) and positive disclosure experiences were associated with HPV vaccination (aPR[95% CI] = 1.46[1.24, 1.71], p < 0.001). Those who disclosed their sexual behavior were more likely than those who did not disclose their sexual behavior to have received an HIV test in their lifetime (negative: aPR[95% CI] = 1.51[1.43, 1.60], p < 0.001; neutral: aPR[95% CI] = 1.61[1.56, 1.66], p < 0.001; positive: aPR[95% CI] = 1.64[1.58, 1.69], p < 0.001) and an HIV test in the past year (negative: aPR[95% CI] = 1.89[1.70, 2.10], p < 0.001; neutral: aPR[95% CI] = 2.09[1.98, 2.20], p < 0.001; positive: aPR[95% CI] = 2.24[2.12, 2.37], p < 0.001). There is a need to implement trainings for healthcare providers that focus on sexual health risk assessments and creating a space that encourages MSM patients and healthcare providers to discuss sexual health.

Gay Dating App Users Support and Utilize Sexual Health Features on Apps.

Men who have sex with men (MSM) frequently meet sex partners through dating apps. Research has demonstrated an association between app use and greater number of sex partners and STIs, but dating apps also pose an opportunity for intervention. By advocating for sexual health features on dating apps, Building Healthy Online Communities (BHOC) aims to increase communication about sexual health among app users. In partnership with Emory University, BHOC added questions to an annual survey of MSM. The questions assessed awareness and uptake of profile fields and sexual health features on the dating apps. Among survey participants, 67% (6737/10,129) reported using dating apps to meet a partner in the past year. Among this group, 77% (4993/6525) reported awareness of sexual health features. 61% of app users (2866/4721) who were aware of them reported using one or more sexual health features. BHOC continues to advocate for increased uptake of these features.

Metrics of sexual behavior stigma among cisgender men who have sex with men in Mexico: exploratory and confirmatory factor analyses.

Cisgender gay, bisexual, and other men who have sex with men (MSM) in Mexico experience disparities in sexual health outcomes, perhaps most notably in HIV prevalence, HIV testing and status awareness, and condom use. Sexual behavior stigma, underpinned by socio-structural factors specific to Mexico (e.g., machismo), uniquely shapes these sexual health disparities. However, few reliable, valid measures are available to document, track, and ultimately mitigate sexual behavior stigma in this context. Exploratory and confirmatory factor analyses were performed on responses to a 13-item sexual behavior stigma scale from 15,681 MSM recruited online across Mexico. Associations with extracted factors were tested to assess construct validity. Three subscales were identified in exploratory factor analysis and validated in confirmatory factor analysis: "stigma from family and friends" (α = 0.65), "anticipated healthcare stigma" (α = 0.84), and "general social stigma" (α = 0.70). External construct validity was indicated through each subscale's strong association (all p < 0.001) with perceived community intolerance of MSM and perceived community discrimination toward people living with HIV. These subscales show promise as reliable, valid measures for assessing sexual behavior stigma among MSM in Mexico, and as tools for documenting and tracking sexual behavior stigma trends, comparing regional burdens of sexual behavior stigma, and tracking the progress of stigma-mitigation interventions among MSM in Mexico. Future research is needed to understand the extent to which each subscale is differentially associated with sexual (and other) health outcomes, which can inform the development and implementation of uniquely tailored stigma-mitigation, HIV-prevention, HIV-care, and other needed interventions for MSM in Mexico.

HIV and Sexually Transmitted Infection Epidemic Potential of Networks of Men Who Have Sex With Men in Two Cities.

BACKGROUND: The speed with which a pathogen circulates in a sexual network is a function of network connectivity. Cross-sectional connectivity is a function of network features like momentary degree and assortative mixing. Temporal connectivity is driven by partner acquisition rates. The forward-reachable path (FRP) has been proposed as a summary measure of these two aspects of transmission potential. We use empirical data from San Francisco and Atlanta to estimate the generative parameters of the FRP and compare results to the HIV/sexually transmitted infection epidemics in each city. METHODS: We used temporal exponential random graph models to estimate the generative parameters for each city's dynamic sexual network from survey data. We then simulated stochastic dynamic networks from the fitted models and calculated the FRP for each realization, overall, and stratified by partnership type and demographics. RESULTS: The overall mean and median paths were higher in San Francisco than in Atlanta. The overall paths for each city were greater than the sum of the paths in each individual partnership network. In the casual partnership network, the mean path was highest in the youngest age group and lowest in the oldest age group, despite the fact that the youngest group had the lowest mean momentary degree and past-year partner counts. CONCLUSIONS: The FRP by age group revealed the additional utility of the measure beyond the temporal and cross-sectional network connectivity measures. Other nonnetwork factors are still necessary to infer total epidemic potential for any specific pathogen.

Effects of Condom Use on Human Immunodeficiency Virus Transmission Among Adolescent Sexual Minority Males in the United States: A Mixed Epidemiology and Epidemic Modeling Study.

BACKGROUND: We examined condom use patterns and potential population-level effects of a hypothetical condom intervention on human immunodeficiency virus (HIV) transmission among adolescent sexual minority males (ASMM). METHODS: Using 3 data sets: national Youth Risk Behavior Survey 2015 to 2017 (YRBS-National), local YRBS data from 8 jurisdictions with sex of partner questions from 2011 to 2017 (YRBS-Trends), and American Men's Internet Survey (AMIS) 2014 to 2017, we assessed associations of condom use with year, age, and race/ethnicity among sexually active ASMM. Using a stochastic agent-based network epidemic model, structured and parameterized based on the above analyses, we calculated the percent of HIV infections averted over 10 years among ASMM ages 13 to 18 years by an intervention that increased condom use by 37% for 5 years and was delivered to 62% of ASMM at age 14 years. RESULTS: In YRBS, 51.8% (95% confidence interval [CI], 41.3-62.3%) and 37.9% (95% CI, 32.7-42.3%) reported condom use at last sexual intercourse in national and trend data sets, respectively. In AMIS, 47.3% (95% CI, 44.6-49.9%) reported condom use at last anal sex with a male partner. Temporal trends were not observed in any data set (P > 0.1). Condom use varied significantly by age in YRBS-National (P < 0.0001) and YRBS-Trends (P = 0.032) with 13- to 15-year-olds reporting the lowest use in both; age differences were not significant in AMIS (P = 0.919). Our hypothetical intervention averted a mean of 9.0% (95% simulation interval, -5.4% to 21.2%) of infections among ASMM. CONCLUSIONS: Condom use among ASMM is low and appears to have remained stable during 2011 to 2017. Modeling suggests that condom use increases, consistent with previous interventions, have potential to avert 1 in 11 new HIV infections among ASMM.

A Behavioral Cascade of HIV Seroadaptation Among US Men Who Have Sex with Men in the Era of PrEP and U = U.

Seroadaptive behaviors help reduce HIV risk for some men who have sex with men (MSM), and have been well documented across MSM populations. Advancements in biomedical prevention have changed the contexts in which seroadaptive behaviors occur. We thus sought to estimate and compare the prevalence of four stages of the "seroadaptive cascade" by PrEP use in the recent era: knowledge of own serostatus, knowledge of partner serostatus; serosorting (matching by status), and condomless anal intercourse. Serosorting overall appeared to remain common, especially with casual and one-time partners. Although PrEP use did not impact status discussion, it did impact serosorting and the likelihood of having condomless anal intercourse. For respondents not diagnosed with HIV and not on PrEP, condomless anal intercourse occurred in just over half of relationships with HIV-positive partners who were not on treatment. Biomedical prevention has intertwined with rather than supplanted seroadaptive behaviors, while contexts involving neither persist.

RESUMEN: Los comportamientos seroadaptivos ayudan a reducir el riesgo de VIH en algunos hombres que tienen sexo con otros hombres (HSH) y han sido bien documentados en varias comunidades de HSH. Los avances en prevención biomédica han cambiado los contextos de los comportamientos seroadaptivos. Por ello buscamos estimar y comparar la prevalencia de cuatro fases de la 'cascada seroadaptiva' mediante el uso de PrEP en la era reciente: conocimiento del seroestatus personal, conocimiento del seroestatus del compañero, serosorting (emparejamiento por estatus) y coito anal sin condón. En general, el serosorting parece seguir siendo común especialmente con parejas casuales o de una noche. A pesar de que el uso de PrEP no impactó la discusión sobre el estatus, sí impactó el serosorting y la probabilidad de coito anal sin condón. Los encuestados no diagnosticados con VIH y sin PrEP tuvieron coito anal sin condón en la mitad de las relaciones con parejas VIH-positivo que no estaban bajo tratamiento. La prevención biomédica se ha entremezclado en lugar de suplantar los comportamientos seropositivos, mientras persisten los contextos en los que no aparece ninguno.

Disclosure of same-sex practices and experiences of healthcare stigma among cisgender men who have sex with men in five sub-Saharan African countries.

BACKGROUND: For men who have sex with men (MSM) across sub-Saharan Africa (SSA), disclosure of same-sex practices to family and healthcare workers (HCWs) can facilitate access to HIV prevention services and support, but can also lead to experiences of stigma. METHODS: We performed mixed-effects regressions on pooled data from MSM in Cameroon, Senegal, Côte d'Ivoire, Lesotho, and eSwatini to assess associations between disclosure and sexual behavior stigma in healthcare contexts; we used logistic regressions to analyze country-specific data. RESULTS: Compared to participants who had not disclosed to either family or HCWs, those who had disclosed only to family were more likely to have been gossiped about by HCWs (aOR = 1.70, CI = 1.18, 2.45); the association between having disclosed to family and having felt mistreated in a health center approached, but did not achieve, statistical significance (aOR = 1.56, CI = 0.94, 2.59). Those who had disclosed only to HCWs were more likely to have feared to seek health services (aOR = 1.60, CI = 1.14, 2.25), avoided health services (aOR = 1.74, CI = 1.22, 2.50), and felt mistreated in a health center (aOR = 2.62, CI = 1.43, 4.81). Those who had disclosed to both were more likely to have feared to seek health services (aOR = 1.71, CI = 1.16, 2.52), avoided health services (aOR = 1.59, CI = 1.04, 2.42), been gossiped about by HCWs (aOR = 3.78, CI = 2.38, 5.99), and felt mistreated in a health center (aOR = 3.39, CI = 1.86, 6.20). Country-specific analyses suggested that data from Cameroon drove several of these associations. CONCLUSIONS: Research to determine the factors driving disclosure's differential effect on healthcare stigma across contexts is needed. Ultimately, supportive environments enabling safe disclosure is critical to understanding HIV-acquisition risks and informing differentiated HIV-prevention, treatment, and testing services for MSM across SSA.

Pre-exposure Prophylaxis Uptake and Discontinuation Among Young Black Men Who Have Sex With Men in Atlanta, Georgia: A Prospective Cohort Study.

BACKGROUND: Human immunodeficiency virus (HIV) preexposure prophylaxis (PrEP) has great potential to reduce HIV incidence among young black men who have sex with men (YBMSM); however, initiation and persistence for this group remain low. We sought to understand the patterns and predictors of PrEP uptake and discontinuation among YBMSM in Atlanta, Georgia. METHODS: PrEP was offered to all participants in a prospective cohort of YBMSM aged 18-29 years not living with HIV. Time to PrEP uptake, first discontinuation, and final discontinuation were assessed using the Kaplan-Meier method. Cox proportional hazard models were used to identify predictors of uptake and discontinuation. RESULTS: After 440 person-years of follow-up, 44% of YBMSM initiated PrEP through the study after a median of 122 days. Of PrEP initiators, 69% had a first discontinuation and 40% had a final discontinuation during the study period. The median time to first PrEP discontinuation was 159 days. Factors associated with PrEP uptake included higher self-efficacy, sexually transmitted infection (STI), and condomless anal intercourse. Factors associated with discontinuation included younger age, cannabis use, STI, and fewer sex partners. HIV incidence was 5.23/100 person-years (95% confidence interval [CI], 3.40-7.23), with a lower rate among those who started PrEP (incidence rate ratio, 0.39; 95% CI, .16-.92). CONCLUSIONS: Persistent PrEP coverage in this cohort of YBMSM was suboptimal, and discontinuations were common despite additional support services available through the study. Interventions to support PrEP uptake and persistence, especially for younger and substance-using YBMSM, are necessary to achieve full PrEP effectiveness. CLINICAL TRIALS REGISTRATION: NCT02503618.

Characterizing Cross-Culturally Relevant Metrics of Stigma Among Men Who Have Sex With Men Across 8 Sub-Saharan African Countries and the United States.

Overcoming stigma affecting gay, bisexual, and other men who have sex with men (MSM) is a foundational element of an effective response to the human immunodeficiency virus (HIV) pandemic. Quantifying the impact of stigma mitigation interventions necessitates improved measurement of stigma for MSM around the world. In this study, we explored the underlying factor structure and psychometric properties of 13 sexual behavior stigma items among 10,396 MSM across 8 sub-Saharan African countries and the United States using cross-sectional data collected between 2012 and 2016. Exploratory factor analyses were used to examine the number and composition of underlying stigma factors. A 3-factor model was found to be an adequate fit in all countries (root mean square error of approximation = 0.02-0.05; comparative fit index/Tucker-Lewis index = 0.97-1.00/0.94-1.00; standardized root mean square residual = 0.04-0.08), consisting of "stigma from family and friends," "anticipated health-care stigma," and "general social stigma," with internal consistency estimates across countries of α = 0.36-0.80, α = 0.72-0.93, and α = 0.51-0.79, respectively. The 3-factor model of sexual behavior stigma cut across social contexts among MSM in the 9 countries. These findings indicate commonalities in sexual behavior stigma affecting MSM across sub-Saharan Africa and the United States, which can facilitate efforts to track progress on global stigma mitigation interventions.

Characterizing the Impact of COVID-19 on Men Who Have Sex with Men Across the United States in April, 2020.

The COVID-19 pandemic is reinforcing health inequities among vulnerable populations, including men who have sex with men (MSM). We conducted a rapid online survey (April 2 to April 13, 2020) of COVID-19 related impacts on the sexual health of 1051 US MSM. Many participants had adverse impacts to general wellbeing, social interactions, money, food, drug use and alcohol consumption. Half had fewer sex partners and most had no change in condom access or use. Some reported challenges in accessing HIV testing, prevention and treatment services. Compared to older MSM, those 15-24 years were more likely to report economic and service impacts. While additional studies of COVID-19 epidemiology among MSM are needed, there is already evidence of emerging interruptions to HIV-related services. Scalable remote solutions such as telehealth and mailed testing and prevention supplies may be urgently needed to avert increased HIV incidence among MSM during the COVID-19 pandemic era.

Birth Cohort and Racial/Ethnic Differences in the Age of First Oral and Anal Sex Among U.S. Men Who Have Sex with Men.

Earlier age of first sex has potential direct and indirect health effects later in life. Though there are multiple nationwide general population studies on ages of first sex, there is no such nationwide study of first male-male oral or anal sex among men who have sex with men (MSM). This may be important for understanding racial/ethnic disparities in HIV and sexually transmitted infection acquisition among young racial/ethnic minority MSM. Our study examined the birth cohort and racial/ethnic differences in ages of first male-male oral and anal sex using a diverse 2015 U.S. nationwide sample of 10,217 sexually active MSM. The mean age of first male-male oral sex was 18.0 years. Compared with older birth cohorts, those MSM born 1990-2000 were more likely to have younger age of first male-male oral sex. Compared to white MSM, Hispanic MSM and non-Hispanic black MSM were more likely to have younger age of first male-male oral sex with a man. The mean age of first male-male anal sex was 20.3 years. Compared with older birth cohorts, those MSM born 1990-2000 were more likely to have younger age of first male-male anal sex. Compared to white MSM, MSM of all other racial/ethnic groups were more likely to have younger age of first male-male anal sex. These findings emphasize the need for comprehensive and MSM-inclusive sexual health education for young teens and online sexual health resources for young gay, bisexual, queer, and other MSM.
