RESUMEN
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.

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.

INTRODUCTION: Many surgeons require patients to quit smoking prior to elective surgeries to reduce the risk of postoperative complications. Our aim was to qualitatively evaluate the communication and care experiences of patients and clinicians involved in conversations about quitting smoking prior to elective orthopaedic surgery. METHODS: A qualitative interview study of rural-residing Veterans, primary care providers (PCPs), and Veterans Administration (VA) orthopaedic surgery staff and pharmacists, who care for rural Veterans. We performed a combination of deductive and inductive approaches to support conventional content analysis using a Patient-Centered Care framework. RESULTS: Patients appreciated a shared approach with their PCP on the plan and reasons for cessation. Despite not knowing if the motivation for elective surgeries served as a teachable moment to facilitate long-term abstinence, almost all clinicians believed it typically helped in the short-term. There was a lack of standardized workflow between primary care and surgery, especially when patients used care delivered outside of VA. CONCLUSIONS: While clinician-provided information about the reasons behind the requirement to quit smoking preoperatively was beneficial, patients appreciated the opportunity to collaborate with their care teams on developing a plan for cessation and abstinence. Other aspects of patient-centered care need to be leveraged, such as the therapeutic alliance or patient-as-person, to build trust and improve communication surrounding tobacco use treatment. System-level changes may need to be made to improve coordination and connection of clinicians within and across disciplines. IMPLICATIONS: This study included perspectives from patients, primary care teams, and surgical teams and found that, in addition to providing information, clinicians need to address other aspects of patient-centered care such as the therapeutic alliance and patient-as-person domains to promote patient engagement in tobacco use treatment. This, in turn, could enhance the potential of surgery as a teachable moment and patient success in quitting smoking.
RESUMEN
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.

BACKGROUND: Oral and anal sex with opposite-sex partners is common and associated with sexually transmitted infection (STI) transmission. Trends in these behaviors over the last decade, during which bacterial STI diagnoses have reached historic highs while HIV diagnoses have decreased, are not well understood. We examined recent trends in oral and anal sex and associated condom use with opposite-sex partners among females and males. METHODS: We analyzed data from 16,926 female and 13,533 male respondents aged 15 to 44 years who reported sex with an opposite-sex partner in the past 12 months from the National Survey of Family Growth, 2011-2019. We used survey-weighted linear or logistic regression to evaluate linear temporal trends in oral and anal sex behaviors. RESULTS: From 2011-2013 to 2017-2019, reports of oral sex and number of oral sex partners in the past 12 months increased among females (85.4% in 2011-2013 to 89.4% in 2017-2019; odds ratio [OR], 1.05 [95% confidence interval {CI}, 1.02-1.09], and ß = 0.014 [95% CI, 0.005-0.023]; respectively) but not males (ranges, 87.9%-89.1%; 1.27-1.31). Condom use at last oral sex decreased among both females and males (6.3%-4.3%: OR, 0.93 [95% CI, 0.88-0.99]; 5.9%-4.4%: OR, 0.95 [95% CI, 0.91-1.00]). Anal sex (ranges, 21.0%-23.3% [females] and 23.3%-24.6% [males]), number of anal sex partners (females, 0.22-0.25; males, 0.26-0.30), and condom use at last anal sex (females, 15.3%-18.2%; males, 27.0%-28.7%) remained stable. CONCLUSIONS: The frequency of oral and anal sex with opposite-sex partners among U.S. 15- to 44-year-olds, paired with limited and-for oral sex-decreasing condom use, demonstrates the need to understand the role of these behaviors in increasing STI diagnosis rates and the potential role of extragenital screening and condoms in reducing STI transmission.

HIV self-testing (HIVST) can improve testing completion among adolescents and young adults (AYA), although its influence on sexual behaviors is unclear. We evaluated whether HIVST was associated with changes in talking with sexual partners about HIVST, condom use, and HIV risk perception among AYA ages 15-24 years in a study of HIVST distribution through homes, pharmacies, and nightclubs in Nairobi, Kenya. All participants had negative HIVST results. Regression models were used to evaluate changes between pre-HIVST and 4 months post-HIVST. Overall, there was a significant increase in talking with sexual partners about HIVST. There was a significant reduction in number of condomless sex acts among AYA recruited through pharmacies and homes. Unexpectedly, among females, there was a significant decrease in consistent condom use with casual partners. HIVST services for AYA may benefit from including strategies to support condom use and partner communication about self-testing adapted to specific populations and partnerships.

Rates of reported gonorrhea and chlamydial infections have increased substantially over the past decade in the USA and disparities persist across age and race/ethnicity. We aimed to understand potential changes in sexual behaviors, sexual network attributes, and sexually transmitted infection (STI) screening that may be contributing to these trends. We analyzed data from 29,423 female and 24,605 male respondents ages 15-44 years from the National Survey of Family Growth, 2008-2019. We used survey-weighted linear or logistic regression to evaluate linear temporal trends in sexual behaviors with opposite-sex partners, network attributes, and STI testing, treatment, and diagnosis. Significant declines were observed in condom use at last vaginal sex, mean number of vaginal sex acts, proportion of condom-protected sex acts in the past 4 weeks, and racial/ethnic homophily with current partners among males and females from 2008-2010 through 2017-2019. Among males, mean number of female partners in the past 12 months and concurrency also declined, while the percent reporting ever having sex with another male increased. Past-year testing for chlamydia and any STI increased among females. Research is needed to understand how these changes interact and potentially contribute to increasing reported gonorrhea and chlamydia diagnoses and identify avenues for future intervention.

Background Portal hypertension in the Fontan circulation is a function of elevated systemic venous pressure and liver fibrosis. Purpose To quantify the prevalence of radiologic evidence of portal hypertension and elevated VAST score (one point each for varices, ascites, splenomegaly, and thrombocytopenia) of 2 or greater in children and adults with Fontan circulation and to determine the association with hemodynamics and adverse outcomes. Materials and Methods This was a retrospective study of individuals with Fontan circulation who underwent abdominal MRI or CT for focal liver lesion surveillance between January 2012 and December 2019. Portal hypertension was defined as the presence of at least two of the following: varices, ascites, or splenomegaly. Fontan deterioration was defined as a composite of heart failure signs or symptoms requiring diuretic escalation, placement of a ventricular assist device, heart transplant, or death. Relationships between variables and the composite end point were assessed using univariable and multivariable logistic regression. Results A total of 123 patients (age range, 9-55 years; 32 children) were evaluated (median age, 23 years; IQR, 17-30 years; 63 male patients). Median time since diagnosis of Fontan circulation was 16 years (IQR, 12-23 years). Twenty-five of the 123 patients (20%) had radiologic evidence of portal hypertension, and 34 (28%) had a VAST score of 2 or greater. Fontan deterioration occurred in 25 of the 123 patients (20%); median follow-up duration was 0.4 year (IQR, 0.1-3.1 years). Compared with patients who had Fontan circulation without deterioration, patients with Fontan deterioration were more likely to have moderate or severe ventricular systolic dysfunction (P < .01), moderate or severe atrioventricular valve regurgitation (P < .01), higher Fontan pressure (P = .01), radiologic evidence of portal hypertension (P < .01), and VAST score of 2 or greater (P < .01). Conclusion Radiologic evidence of portal hypertension at abdominal imaging in children and adults with Fontan circulation was associated with higher venous pressures and an increased risk for Fontan deterioration. These characteristics may be used to identify patients who warrant comprehensive hemodynamic evaluation. © RSNA, 2022.

PURPOSE OF REVIEW: We explored different behavioral economics (BE) mechanisms through which pre-exposure prophylaxis (PrEP) initiation and adherence could be impacted and examined recent work using BE principles to further HIV prevention efforts. We also generated new intervention ideas based on existing HIV testing and ART adherence literature. RECENT FINDINGS: There is limited work that uses BE principles to design interventions to increase PrEP initiation and adherence, mostly involving financial incentives. The recent works highlighted involve financial incentives and demonstrate that key populations are open to accepting monetary incentives to increase PrEP initiation and improve adherence. However, there are mixed results on the long-term impacts of using incentives to modify behavior. While there are a few ongoing studies that utilize BE principles to increase PrEP use, there is need to develop studies that test these concepts, to promote PrEP initiation and adherence. We suggest methods of exploring non-incentives-based ideas to increase PrEP use in key populations.

Internet-based surveys can be programmed and advertised in multiple languages to reach non-English-speaking individuals, but it is unclear the extent to which this enhances the diversity of participants and supports inclusion of individuals at higher risk for HIV. We sought to examine how language of survey completion (English or Spanish) was associated with sociodemographic characteristics and indicators of HIV risk and prevention among cisgender Latino sexual minority men (SMM). We analyzed national and Washington State data using the Understanding New Infections through Targeted Epidemiology (UNITE) Cohort Study (2017 and 2018) and the Washington HIV/STI Prevention Project (WHSPP) survey (2017 and 2018/2019), respectively. Latino SMM who completed online surveys in Spanish differed from those who completed surveys in English across several sociodemographic characteristics including age, education, and income. After adjusting for sociodemographic characteristics and HIV-related risk factors, Spanish language respondents in UNITE were less likely to have tested for HIV in the past year, and those in WHSPP were more likely to report a recent STI diagnosis. Findings suggest that Latino SMM who complete surveys in Spanish comprise a unique subgroup that may have a specific HIV health and risk behavior profile. Our results suggest a need for increased and tailored efforts to recruit and include Spanish-speaking Latino SMM for local and national research and public health programming.
RESUMEN: Encuestas por internet pueden ser programadas y anunciadas para alcanzar a personas que no hablan inglés, pero no queda claro si esto pueda mejorar la diversidad de los participantes de investigación y apoyar la inclusión de los individuos de alto riesgo a infección con el VIH. En este estudio examinamos la relación del idioma de completar la encuesta en línea (inglés o español) entre hombres Latinos de minorías sexuales (HLMS) cisgénero con características sociodemográficas y determinantes para el riesgo y prevención del VIH. Analizamos los datos nacionales y estatales con el estudio de cohorte de Understanding New Infections through Targeted Epidemiology (UNITE) (2017 y 2018) y El Proyecto de Washington para la Prevención del VIH/Infecciones de Transmisión Sexual (WHSPP) (2017 y 2018/2019), respectivamente. Los HLSM quienes completaron las encuestas por internet en español fueron diferentes a los que completaron las encuestas en inglés por varias características sociodemográficas incluso la edad, la educación, y el ingreso. Después de ajustar por las características sociodemográficas y los factores de riesgo asociados con el VIH, los participantes de UNITE que respondieron en español tuvieron menos probabilidad de haberse hecho la prueba de VIH en el año pasado y los que participaron en el WHSPP eran más probable que reportaran un diagnóstico de ITS. Los resultados indican que los HLSM quienes completan las encuestas en español representan un subgrupo distinto que tiene un perfil específico de comportamiento de riesgo y salud respecto al VIH. Los resultados demuestran la necesidad de mayores esfuerzos especializados para reclutar e incluir los HLSM quienes hablan español para que participen en las investigaciones en línea a nivel local y nacional y la programación de la salud pública.

Oral HIV self-testing (HIVST) may expand access to testing among hard-to-reach reach adolescents and young adults (AYA). We evaluated community-based HIVST services for AYA in an urban settlement in Kenya. Peer-mobilizers recruited AYA ages 15-24 through homes, bars/clubs, and pharmacies. Participants were offered oral HIVST, optional assistance and post-test counseling. Outcomes were HIVST acceptance and completion (self-report and returned kits). Surveys were given at enrollment, post-testing, and 4 months. Log-binomial regression evaluated HIVST preferences by venue. Among 315 reached, 87% enrolled. HIVST acceptance was higher in bars/clubs (94%) than homes (86%) or pharmacies (75%). HIVST completion was 97%, with one confirmed positive result. Participants wanted future HIVST at multiple locations, include PrEP, and cost ≤ $5USD. Participants from bars/clubs and pharmacies were more likely to prefer unassisted testing and peer-distributers compared to participants from homes. This differentiated community-based HIVST strategy could facilitate engagement in HIV testing and prevention among AYA.

BACKGROUND: HIV assisted partner services (aPS), or provider notification and testing for sexual and injecting partners of people diagnosed with HIV, is shown to be safe, effective, and cost-effective and was scaled up within the national HIV testing services (HTS) program in Kenya in 2016. We estimated the costs of integrating aPS into routine HTS within an ongoing aPS scale-up project in western Kenya. METHODS: We conducted microcosting using the payer perspective in 14 facilities offering aPS. Although aPS was offered to both males and females testing HIV-positive (index clients), we only collected data on female index clients and their male sex partners (MSP). We used activity-based costing to identify key aPS activities, inputs, resources, and estimated financial and economic costs of goods and services. We analyzed costs by start-up (August 2018), and recurrent costs one-year after aPS implementation (Kisumu: August 2019; Homa Bay: January 2020) and conducted time-and-motion observations of aPS activities. We estimated the incremental costs of aPS, average cost per MSP traced, tested, testing HIV-positive, and on antiretroviral therapy, cost shares, and costs disaggregated by facility. RESULTS: Overall, the number of MSPs traced, tested, testing HIV-positive, and on antiretroviral therapy was 1027, 869, 370, and 272 respectively. Average unit costs per MSP traced, tested, testing HIV-positive, and on antiretroviral therapy were $34.54, $42.50, $108.71 and $152.28, respectively, which varied by county and facility client volume. The weighted average incremental cost of integrating aPS was $7,485.97 per facility per year, with recurrent costs accounting for approximately 90% of costs. The largest cost drivers were personnel (49%) and transport (13%). Providers spent approximately 25% of the HTS visit obtaining MSP contact information (HIV-negative clients: 13 out of 54 min; HIV-positive clients: 20 out of 96 min), while the median time spent per MSP traced on phone and in-person was 6 min and 2.5 hours, respectively. CONCLUSION: Average facility costs will increase when integrating aPS to HTS with incremental costs largely driven by personnel and transport. Strategies to efficiently utilize healthcare personnel will be critical for effective, affordable, and sustainable aPS.

BACKGROUND: Assisted partner service (APS) is effective for increasing HIV testing services (HTS) uptake among sexual partners of people diagnosed with HIV with rare social harm. The acceptability of APS to HTS providers is important for the quality and effectiveness of APS delivery. Within a larger ongoing implementation science study of APS in western Kenya, we qualitatively evaluated the provider acceptability of APS. METHODS: From May-June 2020, we conducted virtual, semi-structured in-depth interviews with 14 HTS providers recruited from 8 of 31 study health facilities in Homa Bay and Kisumu counties. Participants were selected using criteria-based purposive sampling to maximize variation on patient volume (assessed by the number of index clients tested for HIV) and APS performance (assessed by sexual partners elicitation and enrollment). Interviews inquired providers' experiences providing APS including challenges and facilitators and the impact of contextual factors. Data were analyzed using an inductive approach. RESULTS: Overall, HTS providers found APS acceptable. It was consistently reported that doing APS was a continuous process rather than a one-day job, which required building rapport and persistent efforts. Benefits of APS including efficiency in HIV case finding, expanded testing coverage in men, and increased HIV status awareness and linkage to care motivated the providers. Provider referral was perceived advantageous in terms of independent contact with partners on behalf of index clients and efficiency in partner tracing. Challenges of providing APS included protecting clients' confidentiality, difficulty obtaining partners' accurate contact information, logistic barriers of tracing, and clients' refusal due to fear of being judged for multiple sexual partners, fear of breach of confidentiality, and HIV stigma. Building rapport with clients, communicating with patience and nonjudgmental attitude and assuring confidentiality were examples of facilitators. Working in rural areas and bigger facilities, training, supportive supervision, and community awareness of APS promoted APS delivery while low salaries, lack of equipment, and high workload undermined it. CONCLUSIONS: HTS providers found APS acceptable. Delivering APS as a process was the key to success. Future scale-up of APS could consider encouraging provider referral instead of the other APS methods to improve efficiency and reduce potential harm to clients.

BACKGROUND: Syphilis diagnosis relies on serological tests, which may be falsely nonreactive or may be reactive but not reflect current syphilis. METHODS: Polymerase chain reaction for detection of T. pallidum DNA was performed on 123 oropharyngeal swabs, 120 whole bloods, and 46 lesion exudate swabs from 123 untreated individuals with syphilis (cases); oropharyngeal swabs from 148 at-risk controls without syphilis; and 73 oropharyngeal swabs and 36 whole bloods from 73 individuals recently treated for syphilis. RESULTS: Most (90.2%) cases had early syphilis. T. pallidum DNA was detected in 33 (26.8%) of 123 oropharyngeal swabs, 32 (26.7%) of 120 bloods, and 30 (65.2%) of 46 lesion exudate swabs. T. pallidum DNA was detected in 49 (40.8%) of 120 individuals in whom both oropharyngeal swabs and blood were tested. T. pallidum was more likely to be amplified from oropharyngeal swabs when it was amplified from blood than when it was not (15 of 32 [46.9%] vs. 17 of 88 [19.3%], P = 0.003). For each 2-fold increase in serum rapid plasma reagin titer, the odds of detection of T. pallidum DNA in oropharyngeal swabs increased by 1.44 (95% confidence interval, 1.14-1.82, P = 0.003). T. pallidum DNA was not detected in oropharyngeal samples from controls, but it was detected in 3 (8.3%) of 36 bloods from individuals recently treated for syphilis: 2 at 1 day and 1 at 5 days after initiation of syphilis treatment. CONCLUSIONS: Nucleic amplification tests can identify recent T. pallidum infection and may be particularly useful for diagnosis of very early or asymptomatic syphilis.

BACKGROUND: Rates of adolescent sexual activity have long been declining in the United States. We sought to estimate the number of cases of gonorrhea and chlamydia averted over 1 decade associated with these declines and associated costs saved. METHODS: We analyzed data from the Centers for Disease Control and Prevention's Youth Risk Behavior Survey of US high school students from 2007 to 2017 and combined it with epidemiological estimates drawn from the literature to parameterize a dynamic population transmission model. We compared transmissions from observed behavioral trends with a counterfactual scenario that assumed sexual behaviors from 2007 remained constant for 10 years. We calculated outcomes by age and for 3 racial/ethnic groups (Hispanic, non-Hispanic Black, and non-Hispanic White adolescents) who vary on underlying burden and amount of behavioral change. RESULTS: We estimated 1,118,483 cases of chlamydia and 214,762 cases of gonorrhea were averted (19.5% of burden across all ages). This yielded $474 million (2017 dollars) savings in medical costs over the decade. The largest number of averted cases (767,543) was among Black adolescents, but the largest proportion (28.7%) was among Hispanic adolescents. CONCLUSIONS: Whatever its origins, changing sexual behavior among adolescents results in large estimated reductions in STI burden and medical costs relative to previous cohorts. Although diagnoses among adolescents have not declined at this rate, multiple explanations could make these apparently divergent trends consistent. Efforts to continue supporting effective sex education in and out of school along with STI screening for adolescents should reinforce these gains.

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.

BACKGROUND: Voluntary assisted partner notification (aPN) services are effective in increasing access to and uptake of HIV testing among partners of people with HIV. Following recommendations by the World Health Organization in 2016, Indonesia evaluated various approaches to aPN. We present the lessons learned from formative operational research undertaken to understand provider and patient perspectives on aPN from three demonstration sites in cities with a high HIV burden. METHODS: We conducted a formative qualitative study in three cities: Jakarta, Semarang, and Denpasar between September and October 2019. We conducted six focus group discussions (FGDs) (n = 44 participants) among health-care providers, people living with HIV and the general population. We explored participant preferences and concerns about how aPN should be delivered, including the methods of and messaging for contacting partners. All FGDs were conducted in the Indonesian language. Qualitative data were analysed using thematic analysis. RESULTS: aPN was acceptable across different participant populations, although with caveats. Some differences were observed between the general population, providers and people living with HIV. People living with HIV were mainly concerned with confidentiality of the procedure and preferred the use of telecommunication and messages that avoid explicit mention of HIV exposure. Providers preferred similar approaches but for different reasons, being concerned mainly with self-efficacy and security. There was consensus regarding dual referral models. The use of phone calls and short messages were preferred as these are perceived to minimize negative reactions and stigma, protect client confidentiality and are suitable in the current legal situation. The general population was mainly concerned with effectiveness and prefer direct provider-led approaches, such as preferring in-person meeting with explicit notification of potential HIV exposure. CONCLUSIONS: We found consensus among stakeholders on acceptance of aPN, especially dual referral methods. Development and implementation of aPN protocols should also consider clients' individual situations and concerns regarding safeguarding of confidentiality, and offer a range of options to accommodate all stakeholders involved.

BACKGROUND: United States guidelines recommend retesting for chlamydia (CT) and gonorrhea (GC) approximately 3 months after treatment, but adherence to these guidelines is poor. METHODS: In May 2016, the municipal sexually transmitted disease (STD) Clinic in Seattle, WA, integrated opt-in short message system (SMS) (text message) retesting reminders for female patients into our clinic's routine electronic intake. Women were asked if they wanted to receive an SMS reminder for retesting for GC/CT in 3 months. We used Fisher exact tests to compare the proportion who returned to the clinic for retesting and the proportion who retested GC/CT positive 3 to 6 months after their initial diagnosis. We used sexually transmitted disease surveillance data to ascertain repeat GC/CT diagnoses. RESULTS: From May 2016 to December 2017, 743 (36%) of 2067 women opted to receive an SMS reminder. Overall, 95 of these women tested positive for GC or CT and provided a valid phone number; 31 (33%) had opted into SMS reminders. The percentage of women who returned to the clinic 3 to 6 months after their initial GC/CT diagnosis did not significantly differ for women who did and did not opt in to receive SMS reminders (23% vs 9%; P = 0.11). Repeat GC/CT diagnosis 3 to 6 months after the initial GC/CT diagnosis was not significantly different between women who did and did not opt in (7% vs 3%; P = 0.58). CONCLUSIONS: Uptake of automated SMS reminders among women was low, and most women who received reminders did not return for retesting. Despite this, SMS reminders integrated into an existing clinic infrastructure may somewhat increase retesting among women with GC/CT.

BACKGROUND: Geosocial networking (GSN) app use among men who have sex with men (MSM) has presented new opportunities for increasing the reach and efficiency of sexual health interventions but also poses challenges to HIV/sexually transmitted disease partner notification. Understanding MSM's attitudes toward app-based preventive sexual health services can help inform their development and delivery. METHODS: We recruited US MSM who had met a sex partner on GSN apps in the last year to participate in an online survey assessing acceptability and preferences regarding app-based partner notification, health department presence, and sexual health services. Three app-based notification strategies were presented: sending notification messages through participant's/partner's app profile, health department app profile, or in-app anonymous messaging. RESULTS: Of 791 respondents, a majority (70%) preferred to be notified by their partner directly; however, most would get tested if notified by health department profile (95%) or anonymous in-app message (85%). Given the options provided, 50% preferred notifying a partner using their own profile, 26% with health department assistance, and 24% via in-app anonymous message. A majority (71%) were comfortable notifying a partner through a health department profile, and 74% were comfortable using in-app anonymous messaging. Most participants (82%) were comfortable with health departments having app profiles to provide sexual health services. CONCLUSIONS: Our results suggest that GSN app-based partner notification and sexual health services would be used by and are acceptable to US MSM. Partnering with app companies to integrate these services and increase access to public health programs has potential to improve MSM sexual health.

BACKGROUND: HIV self-tests increase HIV status awareness by providing convenience and privacy, although cost and access may limit use. Since 2015, the New York City (NYC) Health Department has conducted 5 waves of an online Home Test Giveaway. METHODS: We recruited adult cisgender men who have sex with men (MSM) and transgender and gender-nonconforming (TGNC) individuals who had sex with men, who were living in NYC, not previously HIV diagnosed, and using paid digital advertisements (4-8 weeks per wave). Eligible respondents were e-mailed a code to redeem on the manufacturer's website for a free HIV self-test and an online follow-up survey ~2 months later. For key process and outcome measures, we present means across 5 waves. RESULTS: Across the 5 waves of Home Test Giveaway, there were 28,921 responses to the eligibility questionnaire: 17,383 were eligible, 12,182 redeemed a code for a free HIV self-test, and 7935 responded to the follow-up survey (46% of eligible responses). Among eligible responses, approximately half were Latino/a (mean, 32%) or non-Latino/a, black (mean, 17%). Mean report of never testing before was 16%. Among 5903 follow-up survey responses who reported test use, 32 reported reactive results with no known previous diagnosis (0.54%), of whom 78% reported receiving confirmatory testing. Report of likelihood of recommending the Home Test Giveaway to friends was high (mean, 96%). CONCLUSIONS: We recruited diverse NYC MSM and TGNC and distributed a large number of HIV self-tests to them. Among respondents who reported newly reactive tests, the majority reported confirmatory testing. This seems to be one acceptable way to reach MSM and TGNC for HIV testing, including those who have never tested before.
