Abstract
OBJECTIVE The aim of this study was to examine trends in HIV incidence among men who have sex with men (MSM) relative to the scale up of Ending the HIV Epidemic (EHE) initiatives, including biomedical prevention strategies, and to describe racial inequities over time. DESIGN A cross-sectional study, matching annual cohorts of New York City (NYC) Sexual Health Clinic (SHC) patients from 2010 to 2018 to the citywide HIV registry to identify seroconversions during 1 year of follow-up, through 2019. METHODS We examined HIV incidence for each annual cohort of MSM using diagnoses within 1 year after last negative HIV test. We calculated incidence rates and rate ratios (IRR) pooled across 3-year intervals (2010-2012, 2013-2015, 2016-2018) by race/ethnicity, age, neighborhood poverty level, recent STI diagnosis, and condom use during anal sex. RESULTS There were 36 156 study visits among MSM attending NYC SHCs, including 37% among White MSM and 63% among MSM of color. From 2010 to 2018, HIV incidence decreased overall from 2.82 to 0.82/100 person-years, and among all race/ethnicity, age, poverty, STI, and condom use subgroups. For 2010-2012 vs. 2016-2018, adjusted IRRs (95% CI) increased for Black MSM [1.8 (1.3-2.6) vs. 6.0 (3.5-10.2)], Latino MSM [1.4 (1.0-2.0) vs. 4.0 (2.3-6.8)], and MSM of other races [1.0 (0.6-1.7) vs. 2.5 (1.3-4.9)] compared with White MSM. Black and Latino MSM seroconverted at significantly higher rates than White MSM in the same age groups and neighborhood poverty level. CONCLUSION Despite decreases in HIV incidence among MSM, racial inequities were exacerbated over time. Addressing structural factors that impact racial inequities in risk of HIV should undergird EHE initiatives.

[PMID: 38771970 DOI: 10.1080/09540121.2024.2354207] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/06/2023] [Accepted: 05/07/2024] [Indexed: 05/23/2024]
Abstract
This study aimed to measure the pooled estimate of willingness to use HIV pre-exposure prophylaxis (PrEP) (WTUP) among PrEP-naïve United States (U.S.)-based men who have sex with men (MSM). PubMed, Embase, Web of Science, CINAHL, and PsycINFO were searched. The search strategy contained the keyword willingness and interest and the MeSH terms for HIV and PrEP. Articles were included if they were published between January 2005 and May 2022, reported quantitative data on WTUP among PrEP-naïve US-based MSM, and were available as full text in English. Meta-analysis was conducted to assess the pooled effect size of WTUP prevalence using a random-effects model, heterogeneity in the pooled estimate was assessed, and subgroup analyzes were conducted. Fifteen studies were included based on the inclusion and exclusion criteria. Meta-analysis revealed a pooled prevalence proportion for WTUP of 0.58 (95% CI 0.54-0.61) (or 58 out of 100) among PrEP-naïve MSM. High inter-study heterogeneity (Q = 548.10, df = 19, p < 0.01, I2 = 96.53, τ2 = 0.09) was observed. Age of the study sample and region where the data were collected significantly moderated the pooled WTUP estimate. Age-appropriate PrEP related messaging and a focus on HIV priority areas of the U.S. would be important strategies to improve WTUP among MSM in the U.S. moving forward.

Am J Epidemiol 2024; 193:6-16. [PMID: 37073419 PMCID: PMC10773485 DOI: 10.1093/aje/kwad097] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/14/2022] [Revised: 01/08/2023] [Accepted: 04/13/2023] [Indexed: 04/20/2023] Open
Abstract
Antiretroviral preexposure prophylaxis (PrEP) is highly effective in preventing human immunodeficiency virus (HIV) infection, but uptake has been limited and inequitable. Although interventions to increase PrEP uptake are being evaluated in clinical trials among men who have sex with men (MSM), those trials cannot evaluate effects on HIV incidence. Estimates from observational studies of the causal effects of PrEP-uptake interventions on HIV incidence can inform decisions about intervention scale-up. We used longitudinal electronic health record data from HIV-negative MSM accessing care at Fenway Health, a community health center in Boston, Massachusetts, from January 2012 through February 2018, with 2 years of follow-up. We considered stochastic interventions that increased the chance of initiating PrEP in several high-priority subgroups. We estimated the effects of these interventions on population-level HIV incidence using a novel inverse-probability weighted estimator of the generalized g-formula, adjusting for baseline and time-varying confounders. Our results suggest that even modest increases in PrEP initiation in high-priority subgroups of MSM could meaningfully reduce HIV incidence in the overall population of MSM. Interventions tailored to Black and Latino MSM should be prioritized to maximize equity and impact.

Abstract
BACKGROUND Black cisgender gay, bisexual, and other sexual minority men (SMM) and transgender women (TW) continue to be heavily affected by HIV. Further research is needed to better understand HIV prevention and care outcomes in this population. In particular, there is a need for research examining the impact of substance use and sleep health on HIV prevention and treatment outcomes among Black SMM and TW. OBJECTIVE This paper outlines the study methods being used in the recently launched follow-up study to the Neighborhoods and Networks (N2) study, which we refer to as N2 Part 2 (N2P2). N2P2 aims to address this gap in the literature, build off the findings of the original N2 study, and identify socioenvironmental determinants of health, including whether neighborhood and network factors mediate and moderate these relationships. METHODS Building on the N2 cohort study in Chicago from 2018 to 2022, N2P2 used a prospective longitudinal cohort design and an observational-implementation hybrid approach. With sustained high levels of community engagement, we aim to recruit a new sample of 600 Black SMM and TW participants residing in the Chicago metropolitan statistical area. Participants are asked to participate in 3 study visits across an 18-month study period (1 visit every 9 months). Four different forms of data are collected per wave: (1) an in-person survey, (2) biological specimen collection, (3) a daily remote ecological momentary assessment for 14 days after each study visit, and (4) data from electronic health records. These forms of data collection continue to assess neighborhood and network factors and specifically explore substance use, sleep, immune function, obesity, and the implementation of potential interventions that address relevant constructs (eg, alcohol use and pre-exposure prophylaxis adherence). RESULTS The N2P2 study was funded in August 2021 by the National Institute of Drug Abuse (R01DA054553 and R21DA053156) and National Heart, Lung, and Blood Institute (R01HL160325). This study was launched in November 2022. Recruitment and enrollment for the first wave of data collection are currently ongoing. CONCLUSIONS The N2P2 study is applying innovative methods to comprehensively explore the impacts of substance use and sleep health on HIV-related outcomes among an HIV status-neutral cohort of Black SMM and TW in Chicago. This study is applying an observational-implementation hybrid design to help us achieve findings that support rapid translation, a critical priority among populations such as Black SMM and TW that experience long-standing inequities with regard to HIV and other health-related outcomes. N2P2 will directly build off the findings that have resulted from the original N2 study among Black SMM and TW in Chicago. These findings provide a better understanding of multilevel (eg, individual, network, and neighborhood) factors that contribute to HIV-related outcomes and viral suppression among Black SMM and TW.

Abstract
BACKGROUND Oral HIV preexposure prophylaxis (PrEP) is safe and effective but underutilized. Health care providers' beliefs about PrEP and attitudes toward people who could benefit may affect PrEP access. METHODS This mixed-methods study (2016-2018) was conducted in 8 New York City public sexual health clinics that implemented a PrEP program. Data included 32 in-depth qualitative interviews with clinicians, quantitatively coded to reflect their PrEP beliefs; a provider questionnaire; and 6 months of medical record visit data for these providers. Among patients with a PrEP indication, we examined the odds of a patient being initiated on PrEP associated with providers' PrEP beliefs and demographic characteristics, and patient characteristics. RESULTS Providers reported strong support for offering PrEP to eligible patients. The majority denied concerns about possible development of drug-resistant viral strains, giving PrEP to people who might not benefit, and PrEP toxicity. Nevertheless, about one-third agreed with each of these concerns, and 55% thought PrEP use might limit condom use. Of 2176 patients with a PrEP indication, 20% were initiated. Providers with more restrictive PrEP beliefs did not have lower odds of initiating patients on PrEP. Women as well as Black and Latinx patients were less likely to be initiated on PrEP. CONCLUSIONS Contrary to our hypotheses, providers' negative PrEP beliefs did not seem to reduce initiation of PrEP for eligible patients. This may be attributable to clear clinical protocols, strong staff support, and training on implementing PrEP in this setting. Racial and gender disparities in PrEP uptake urgently require attention.

Achieving the "Ending the HIV Epidemic in the U.S." incidence reduction goals among at-risk populations in the South. BMC Public Health 2023; 23:716. [PMID: 37081482 PMCID: PMC10116101 DOI: 10.1186/s12889-023-15563-5] [Citation(s) in RCA: 3] [Impact Index Per Article: 3.0] [Reference Citation Analysis] [Abstract] [Key Words] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/30/2022] [Accepted: 03/29/2023] [Indexed: 04/22/2023] Open
Abstract
INTRODUCTION Antiretroviral medication coverage remains sub-optimal in much of the United States, particularly the Sothern region, and Non-Hispanic Black or African American persons (NHB) continue to be disproportionately impacted by the HIV epidemic. The "Ending the HIV Epidemic in the U.S." (EHE) initiative seeks to reduce HIV incidence nationally by focusing resources towards the most highly impacted localities and populations. This study evaluates the impact of hypothetical improvements in ART and PrEP coverage to estimate the levels of coverage needed to achieve EHE goals in the South. METHODS We developed a stochastic, agent-based network model of 500,000 individuals to simulate the HIV epidemic and hypothetical improvements in ART and PrEP coverage. RESULTS New infections declined by 78.6% at 90%/40% ART/PrEP and 94.3% at 100%/50% ART/PrEP. Declines in annual incidence rates surpassed 75% by 2025 with 90%/40% ART/PrEP and 90% by 2030 with 100%/50% ART/PrEP coverage. Increased ART coverage among NHB MSM was associated with a linear decline in incidence among all MSM. Declines in incidence among Hispanic/Latino and White/Other MSM were similar regardless of which MSM race group increased their ART coverage, while the benefit to NHB MSM was greatest when their own ART coverage increased. The incidence rate among NHB women declined by over a third when either NHB heterosexual men or NHB MSM increased their ART use respectively. Increased use of PrEP was associated with a decline in incidence for the groups using PrEP. MSM experienced the largest absolute declines in incidence with increasing PrEP coverage, followed by NHB women. CONCLUSIONS Our analysis indicates that it is possible to reach EHE goals. The largest reductions in HIV incidence can be achieved by increasing ART coverage among MSM and all race groups benefit regardless of differences in ART initiation by race. Improving ART coverage to > 90% should be prioritized with a particular emphasis on reaching NHB MSM. Such a focus will reduce the largest number of incident cases, reduce racial HIV incidence disparities among both MSM and women, and reduce racial health disparities among persons with HIV. NHB women should also be prioritized for PrEP outreach.

Abstract
Despite documented efficacy in reducing HIV transmission, pre-exposure prophylaxis (PrEP) uptake among Black sexual minority men (BSMM) is limited. One understudied factor which may impede PrEP uptake is PrEP-related interactive toxicity beliefs (i.e., believing it is hazardous to use alcohol/drugs while taking PrEP). Data from N = 169 HIV negative BSMM over 4 months showed high rates of agreement with at least one alcohol (78%) or drug (84%) interactive toxicity belief. Univariate analyses showed increased alcohol or drug interactive toxicity beliefs predicted lower PrEP uptake. Multivariable regression suggested those with PrEP-related alcohol or drug interactive toxicity beliefs were more likely to report high PrEP stigma, more negative PrEP beliefs (e.g., concern that taking PrEP disrupts life), and were more likely to use alcohol/drugs (respectively) prior to/during sex. Findings warrant intervention work targeting interactive toxicity beliefs with tailored messaging to mitigate PrEP stigma and correct concerns around substance use and PrEP.

Abstract
Pre-exposure prophylaxis (PrEP) is highly effective for prevention of HIV transmission and plays an important role in efforts to end the HIV epidemic within the next decade. However, disparities in access to PrEP might be fuelling disparities in the burden of HIV in the USA. The advent of next-generation PrEP formulations that do not involve daily regimens (eg, long-acting cabotegravir) holds potential to facilitate medication adherence, but if the roll-out of these formulations does not consider disparities in access, HIV disparities might be further widened. On the basis of US epidemiological data and informed by the Theory of Fundamental Causes of Health Disparities, we propose an equity-promoting framework to guide the implementation of daily oral and next-generation PrEP. Multilevel efforts to bolster equity in PrEP care include generating demand for next-generation PrEP formulations among marginalised groups, expanding the availability of health services providing oral and next-generation PrEP, and addressing structural and financial barriers to HIV prevention care. The aim of these strategies is to realise the potential of next-generation PrEP to provide people at high risk with effective options to prevent HIV acquisition, thereby helping to reduce both overall HIV transmission and health disparities in the USA.

Abstract
OBJECTIVE To estimate trends in the proportion of sexually active U.S. adults with HIV (PWH) reporting an HIV-discordant sexual partner taking preexposure prophylaxis (PrEP) and proportion of partners taking PrEP. DESIGN The Medical Monitoring Project is a complex sample survey of U.S. adults with diagnosed HIV. METHODS We used annual cross-sectional data collected during June 2015-May 2020 to estimate the annual percentage change (EAPC), overall and by selected characteristics, in reported partner PrEP use among PWH with HIV-discordant partners (N = 8707) and reported PrEP use among these partners (N = 15 844). RESULTS The proportion of PWH reporting PrEP use by one or more HIV-discordant sex partner rose 19.5% annually (11.3 to 24.4%). The prevalence rose from 6.0 to 17.4% (EAPC, 25.8%) among Black PWH, 10.1 to 26.0% (EAPC, 19.5%) among Hispanic/Latino PWH, and 20.8 to 34.6% (EAPC, 16.3%) among White PWH. Among MSM with HIV, the prevalence increased from 9.6 to 32.6% (EAPC, 28.2%) among Black MSM, 16.6 to 36.0% (EAPC, 15.6%) among Hispanic/Latino MSM, and 24.9 to 44.1% (EAPC, 17.9%) among White MSM. Among HIV-discordant sex partners, the proportion reported to be taking PrEP increased 21.1% annually (7.8 to 18.8%). Reported PrEP use rose from 4.9 to 14.2% (EAPC, 29.9%) among Black partners, 6.5 to 16.8% (EAPC, 20.3%) among Hispanic/Latino partners, and 12.7 to 26.1% (EAPC, 17.0%) among White partners. CONCLUSIONS One in five HIV-discordant sexual partners of PWH was reported to be taking PrEP. PrEP use rose among all examined populations, although the increases did not eliminate disparities in PrEP use.

Abstract
BACKGROUND HIV partner services can accelerate the use of antiretroviral-based HIV prevention tools (antiretroviral therapy [ART] and preexposure prophylaxis [PrEP]), but its population impact on long-term HIV incidence reduction is challenging to quantify with traditional partner services metrics of partner identified or HIV screened. Understanding the role of partner services within the portfolio of HIV prevention interventions, including using it to efficiently deliver antiretrovirals, is needed to achieve HIV prevention targets. METHODS We used a stochastic network model of HIV/sexually transmitted infection transmission for men who have sex with men, calibrated to surveillance-based estimates in the Atlanta area, a jurisdiction with high HIV burden and suboptimal partner services uptake. Model scenarios varied successful delivery of partner services cascade steps (newly diagnosed "index" patient and partner identification, partner HIV screening, and linkage or reengagement of partners in PrEP or ART care) individually and jointly. RESULTS At current levels observed in Atlanta, removal of HIV partner services had minimal impact on 10-year cumulative HIV incidence, as did improving a single partner services step while holding the others constant. These changes did not sufficiently impact overall PrEP or ART coverage to reduce HIV transmission. If all index patients and partners were identified, maximizing partner HIV screening, partner PrEP provision, partner ART linkage, and partner ART reengagement would avert 6%, 11%, 5%, and 18% of infections, respectively. Realistic improvements in partner identification and service delivery were estimated to avert 2% to 8% of infections, depending on the combination of improvements. CONCLUSIONS Achieving optimal HIV prevention with partner services depends on pairing improvements in index patient and partner identification with maximal delivery of HIV screening, ART, and PrEP to partners if indicated. Improving the identification steps without improvement to antiretroviral service delivery steps, or vice versa, is projected to result in negligible population HIV prevention benefit.

Abstract
BACKGROUND Population-level estimates of sexual network mixing for parameterizing prediction models of pre-exposure prophylaxis (PrEP) effectiveness are needed to inform prevention of HIV transmission among men who have sex with men (MSM). Estimates obtained by egocentric sampling are vulnerable to information bias due to incomplete respondent knowledge. METHODS We estimated patterns of serosorting and PrEP sorting among MSM in the United States using data from a 2017-2019 egocentric sexual network study. Respondents served as proxies to report the HIV status and PrEP use of recent sexual partners. We contrasted results from a complete-case analysis (unknown HIV and PrEP excluded) versus a bias analysis with respondent-reported data stochastically reclassified to simulate unobserved self-reported data from sexual partners. RESULTS We found strong evidence of preferential partnering across analytical approaches. The bias analysis showed concordance between sexual partners of HIV diagnosis and PrEP use statuses for MSM with diagnosed HIV (39%; 95% simulation interval: 31, 46), MSM who used PrEP (32%; 21, 37), and MSM who did not use PrEP (83%; 79, 87). The fraction of partners with diagnosed HIV was higher among MSM who used PrEP (11%; 9, 14) compared with MSM who did not use PrEP (4%; 3, 5). Comparatively, across all strata of respondents, the complete-case analysis overestimated the fractions of partners with diagnosed HIV or PrEP use. CONCLUSIONS We found evidence consistent with HIV and PrEP sorting among MSM, which may decrease the population-level effectiveness of PrEP. Bias analyses can improve mixing estimates for parameterization of transmission models.

Abstract
PURPOSE Identification of disparity in preexposure prophylaxis (PrEP) prescription by demographic group. DESIGN Exploratory descriptive study. METHODS Secondary data analysis of 1114 patients who received PrEP from Planned Parenthood League of Massachusetts (PPLM) between 2017 and 2020. FINDINGS Persons of Asian racial-identity had a higher mean PrEP prescription than the other racial groups. Persons over 30 had a higher mean PrEP prescription than those 18-29. CONCLUSIONS Discrepancy of PrEP prescription reveals opportunities to improve PrEP delivery. CLINICAL EVIDENCE Providers of PrEP delivery and community health nurses can enhance delivery by better electronic medical charting regarding PrEP discussion and nonadherence.

Abstract
Pre-exposure prophylaxis (PrEP) is a highly efficacious HIV prevention medication, yet Black and Hispanic/Latino sexual minority men's and gender diverse individuals' (SMMGD) PrEP use is limited due to factors such as PrEP barriers and anticipated PrEP stigma. Although most individuals who use PrEP take it as a daily regimen, there is evidence that many SMMGD are interested in using "on-demand" (also known as event-driven or intermittent or 2-1-1) PrEP. We used stepwise multinomial logistic regression to explore factors associated with on-demand, daily, and no PrEP use among 820 Black and Hispanic/Latino SMMGD ages 18-29 in the United States. We found that greater reported PrEP barriers were associated with higher odds of using PrEP on-demand or not using PrEP compared to daily PrEP use. More past 3-month sex partners and greater comfort telling others about PrEP use were associated with lower odds of on-demand compared to daily PrEP use. In addition, compared to daily PrEP use, more past 3-month sex partners, greater comfort telling others about PrEP use, and higher anticipated PrEP stigma were associated with lower odds of no current PrEP use compared to daily PrEP use. Findings may inform clinical practices and interventions to promote PrEP uptake and adherence.

Abstract
BACKGROUND Up to 69% of adults who acquire HIV in Kenya seek care before seroconversion, providing an important opportunity for early diagnosis and treatment. The Tambua Mapema Plus (TMP) trial tested a combined HIV-1 nucleic acid testing, linkage, treatment, and partner notification intervention for adults aged 18-39 years with symptoms of acute HIV infection presenting to health facilities in coastal Kenya. We estimated the potential impact of TMP on the Kenyan HIV epidemic. METHODS We developed an agent-based network model of HIV-1 transmission using TMP data and Kenyan statistics to estimate potential population-level impact of targeted facility-based testing over 10 years. Three scenarios were modeled: standard care [current use of provider-initiated testing and counseling (PITC)], standard HIV rapid testing scaled to higher coverage obtained in TMP (scaled-up PITC), and the TMP intervention. RESULTS Standard care resulted in 90.7% of persons living with HIV (PLWH) knowing their status, with 67.5% of those diagnosed on treatment. Scaled-up PITC resulted in 94.4% of PLWH knowing their status and 70.4% of those diagnosed on treatment. The TMP intervention achieved 97.5% of PLWH knowing their status and 80.6% of those diagnosed on treatment. The percentage of infections averted was 1.0% (95% simulation intervals: -19.2% to 19.9%) for scaled-up PITC and 9.4% (95% simulation intervals: -8.1% to 24.5%) for TMP. CONCLUSION Our study suggests that leveraging new technologies to identify acute HIV infection among symptomatic outpatients is superior to scaled-up PITC in this population, resulting in >95% knowledge of HIV status, and would reduce new HIV infections in Kenya.

Abstract
Racial and ethnic minority men who have sex with men (MSM) are disproportionately affected by HIV/AIDS in Los Angeles County (LAC), an important epicenter in the battle to end HIV. We examine tradeoffs between effectiveness and equality of pre-exposure prophylaxis (PrEP) allocation strategies among different racial and ethnic groups of MSM in LAC and provide a framework for quantitatively evaluating disparities in HIV outcomes. To do this, we developed a microsimulation model of HIV among MSM in LAC using county epidemic surveillance and survey data to capture demographic trends and subgroup-specific partnership patterns, disease progression, patterns of PrEP use, and patterns for viral suppression. We limit analysis to MSM, who bear most of the burden of HIV/AIDS in LAC. We simulated interventions where 3000, 6000, or 9000 PrEP prescriptions are provided annually in addition to current levels, following different allocation scenarios to each racial/ethnic group (Black, Hispanic, or White). We estimated cumulative infections averted and measures of equality, after 15 years (2021-2035), relative to base case (no intervention). By comparing allocation strategies on the health equality impact plane, we find that, of the policies evaluated, targeting PrEP preferentially to Black individuals would result in the largest reductions in incidence and disparities across the equality measures we considered. This result was consistent over a range of PrEP coverage levels, demonstrating that there are "win-win" PrEP allocation strategies that do not require a tradeoff between equality and efficiency.

Abstract
BACKGROUND Pre-exposure prophylaxis (PrEP) is essential to ending HIV. Yet, uptake remains uneven across racial and ethnic groups. We aimed to estimate the impacts of alternative PrEP implementation strategies in Los Angeles County. SETTING Men who have sex with men, residing in Los Angeles County. METHODS We developed a microsimulation model of HIV transmission, with inputs from key local stakeholders. With this model, we estimated the 15-year (2021-2035) health and racial and ethnic equity impacts of 3 PrEP implementation strategies involving coverage with 9000 additional PrEP units annually, above the Status-quo coverage level. Strategies included PrEP allocation equally (strategy 1), proportionally to HIV prevalence (strategy 2), and proportionally to HIV diagnosis rates (strategy 3), across racial and ethnic groups. We measured the degree of relative equalities in the distribution of the health impacts using the Gini index (G) which ranges from 0 (perfect equality, with all individuals across all groups receiving equal health benefits) to 1 (total inequality). RESULTS HIV prevalence was 21.3% in 2021 [Black (BMSM), 31.1%; Latino (LMSM), 18.3%, and White (WMSM), 20.7%] with relatively equal to reasonable distribution across groups (G, 0.28; 95% confidence interval [CI], 0.26 to 0.34). During 2021-2035, cumulative incident infections were highest under Status-quo (n = 24,584) and lowest under strategy 3 (n = 22,080). Status-quo infection risk declined over time among all groups but remained higher in 2035 for BMSM (incidence rate ratio, 4.76; 95% CI: 4.58 to 4.95), and LMSM (incidence rate ratio, 1.74; 95% CI: 1.69 to 1.80), with the health benefits equally to reasonably distributed across groups (G, 0.32; 95% CI: 0.28 to 0.35). Relative to Status-quo, all other strategies reduced BMSM-WMSM and BMSM-LMSM disparities, but none reduced LMSM-WMSM disparities by 2035. Compared to Status-quo, strategy 3 reduced the most both incident infections (% infections averted: overall, 10.2%; BMSM, 32.4%; LMSM, 3.8%; WMSM, 3.5%) and HIV racial inequalities (G reduction, 0.08; 95% CI: 0.02 to 0.14). CONCLUSIONS Microsimulation models developed with early, continuous stakeholder engagement and inputs yield powerful tools to guide policy implementation.

Abstract
CONTEXT African American and Hispanic adults share a disproportionate burden of HIV infections in the United States but continue to experience suboptimal uptake of HIV pre-exposure prophylaxis (PrEP). Increasing PrEP accessibility in nontraditional care settings is a potential strategy to increase PrEP uptake in these high-risk groups. PrEP implementation in local health departments (LHDs) is not well characterized. OBJECTIVE To evaluate HIV PrEP implementation for African American and Hispanic adults receiving medical care in Virginia's LHDs. DESIGN We conducted a retrospective, mixed-methods evaluation of PrEP services implementation at LHDs completing their first PrEP program year between June 1, 2016, and June 30, 2019. Using pharmacy records, we estimated PrEP coverage and adherence using PrEP to need ratios (PnRs) and medication possession ratios (MPRs), respectively. Thematic analysis was used to identify barriers to PrEP delivery in interviews with 6 multidisciplinary LHD workers. RESULTS Of the 433 PrEP clients receiving an emtricitabine/tenofovir disoproxil fumarate (Truvada) prescription in year 1, 52.0% self-identified as African American and 8.9% self-identified as Hispanic. PnRs were greater for White adults in 50.0% of clinics. The average MPR (0.79) was consistent with protective medication adherence levels; however, 25.0% of clients filled only one prescription in the program year. Qualitative findings suggest incompatibilities between health PrEP services delivery and community preferences for African American and Hispanic adults; however, LHDs in one health region were able to link communities of color to PrEP at similar rates as Whites. CONCLUSIONS Incorporating a metric sensitive to racial/ethnic differences in the burden of HIV infection improved recognition of PrEP disparities; however, population-specific targets are needed to enhance use of the PnR for program evaluation. Tailoring of PrEP services to communities with the greatest local PrEP burden may be needed to optimize the effectiveness of PrEP programs in LHDs.

Abstract
Egocentric sampling of networks selects a subset of nodes ("egos") and collects information from them on themselves and their immediate network neighbours ("alters"), leaving the rest of the nodes in the network unobserved. This design is popular because it is relatively inexpensive to implement and can be integrated into standard sample surveys. Recent methodological developments now make it possible to statistically analyse this type of network data with Exponential-family Random Graph Models (ERGMs). This provides a framework for principled statistical inference, and the fitted models can in turn be used to simulate complete networks of arbitrary size that are consistent with the observed sample data, allowing one to infer the distribution of whole-network properties generated by the observed egocentric network statistics. In this paper, we discuss how design choices for egocentric network studies impact statistical estimation and inference for ERGMs. The design choices include both measurement strategies (for ego and alter attributes, and for ego-alter and alter-alter ties) and sampling strategies (for egos and alters). We discuss the importance of harmonising measurement specifications across egos and alters, and conduct simulation studies to demonstrate the impact of sampling design on statistical inference, specifically stratified sampling and degree censoring.

Abstract
Inequities in pre-exposure prophylaxis (PrEP) experiences will impede HIV epidemic elimination among gay and bisexual men (GBM). Ethnicity is a strong marker of inequity in the United States, but evidence from other countries is lacking. We investigated experiences on-PrEP to 12 months follow-up in a prospective cohort of 150 GBM in Auckland, New Zealand with an equity quota of 50% non-Europeans. Retention at 12 months was 85.9%, lower among Māori/Pacific (75.6%) than non-Māori/Pacific participants (90.1%). Missed pills increased over time and were higher among Māori/Pacific. PrEP breaks increased, by 12 months 35.7% of Māori/Pacific and 15.7% of non-Māori/Pacific participants had done so. Condomless receptive anal intercourse partners were stable over time. STIs were common but chlamydia declined; 12-month incidence was 8.7% for syphilis, 36.0% gonorrhoea, 46.0% chlamydia, 44.7% rectal STI, 64.0% any STI. Structural interventions and delivery innovations are needed to ensure ethnic minority GBM gain equal benefit from PrEP. Clinical trial number ACTRN12616001387415.

Abstract
Introduction: HIV pre-exposure prophylaxis (PrEP) in the form of a daily oral medication is highly effective at preventing HIV. In the United States, awareness about PrEP has steadily increased over time among individuals vulnerable to HIV, however awareness has not translated into widescale uptake. Estimates are that fewer than 20% of 1.2 million Americans for whom PrEP is indicated are utilizing it. We sought to understand how individuals moved from PrEP awareness to PrEP utilization. Methods: We conducted a series (n = 31) of in-depth interviews with young people, predominantly gay and bisexual men, ages 18–29 years old between February 2015 and January 2016, as part of the evaluation of a multi-year demonstration project funded to test innovative approaches to improve sexual health outcomes and curb the HIV epidemic in California. Interviews were audio-recorded and transcribed verbatim. We conducted a thematic analysis. Results: We present a continuum of PrEP awareness that spans three phases—basic, moderate and advanced. Participants rarely reported becoming well-informed about PrEP over the course of an initial exposure to PrEP information. Learning occurred after multiple exposures to PrEP information through numerous intersecting forms, messengers and formal and informal communication channels. Positively framed messages delivered by formal messengers emphasizing PrEP as a sensible HIV prevention strategy and explicitly communicating a regard for sexual wellness were overwhelmingly persuasive and facilitated movement to the advanced awareness phase. Once participants reached the advanced phase of PrEP awareness, uptake was possible. Conclusions: Our analysis provides insights into how PrEP awareness led to PrEP uptake among young gay and bi-sexual men. Building demand among those in the basic awareness phase took longer than those in the moderate phase. Individuals involved in formal and informal PrEP education can set reasonable expectations about whether, when and how eventual uptake may occur when keeping the continuum of PrEP awareness framework in mind. Many young, gay and bi-sexual male prospective PrEP users will benefit from positively framed messages that emphasize personal well-being, including social, sexual and emotional benefits of PrEP use.

Abstract
BACKGROUND Key components of Ending the HIV Epidemic (EHE) plan include increasing HIV antiretroviral therapy (ART) and HIV pre-exposure prophylaxis (PrEP) coverage. One complication to addressing this service delivery challenge is the wide heterogeneity of HIV burden and health care access across the United States. It is unclear how the effectiveness and efficiency of expanded PrEP will depend on different baseline ART coverage. METHODS We used a network-based model of HIV transmission for men who have sex with men (MSM) in San Francisco. Model scenarios increased varying levels of PrEP coverage relative under current empirical levels of baseline ART coverage and 2 counterfactual levels. We assessed the effectiveness of PrEP with the cumulative percentage of infections averted (PIA) over the next decade and efficiency with the number of additional person-years needed to treat (NNT) by PrEP required to avert one HIV infection. RESULTS In our projections, only the highest levels of combined PrEP and ART coverage achieved the EHE goals. Increasing PrEP coverage up to 75% showed that PrEP effectiveness was higher at higher baseline ART coverage. Indeed, the PIA was 61% in the lowest baseline ART coverage population and 75% in the highest. The efficiency declined with increasing ART (NNT range from 41 to 113). CONCLUSIONS Improving both PrEP and ART coverage would have a synergistic impact on HIV prevention even in a high baseline coverage city such as San Francisco. Efforts should focus on narrowing the implementation gaps to achieve higher levels of PrEP retention and ART sustained viral suppression.

Abstract
Pre-exposure prophylaxis (PrEP) is highly effective at preventing HIV acquisition and is a critical tool in the Ending the HIV Epidemic in the U.S. initiative. However, major racial and ethnic disparities across the pre-exposure prophylaxis continuum, secondary to structural inequities and systemic racism, threaten progress. Many barriers, operating at the individual, network, healthcare, and structural levels, impede PrEP access and uptake within Black and Hispanic/Latino communities. This review provides an overview of those barriers and the innovative and collaborative solutions that health departments, healthcare organizations, and community partners have implemented to increase PrEP provision and uptake among disproportionately affected communities. Promising strategies at the individual and network levels focus on increasing patient support throughout the PrEP continuum, positioning and training community members to expand knowledge of and interest in PrEP, and leveraging mobile technologies to support PrEP uptake. Healthcare-level solutions include expanding the venues and types of healthcare professionals that can provide PrEP, and structural- and policy-level options focus on financial assistance programs and health insurance expansion. Key research gaps include demonstrating that pilot studies and interventions remain effective at scale and across varied contexts. Although the last 2 decades have provided effective tools to end the HIV epidemic, realizing this vision for the U.S. will require addressing persistent and pervasive HIV-related disparities in Black and Hispanic/Latino communities. Federal, state, and local partners should expand efforts to address longstanding health and structural inequities and partner with disproportionately affected communities to rapidly expand PrEP scale-up.

Abstract
This study investigated sexual identity and behavior and their potential associations with PrEP use and attitudes in cisgender Black gay and bisexual men. A total of N = 173 (mean age 25.2) participants from the Neighborhoods and Networks (N2) Study in Chicago were included. Of these, 104 were gay-identified and reported sex with men only (GSMO), 26 were gay-identified and reported sex with men and women (GSMW), 8 were bisexual-identified and reported sex with men only (BSMO), and 35 were bisexual-identified and reported sex with men and women (BSMW). Reporting sex with men and women in the past 6 months, RR = 0.39, 95% CI [0.17, 0.89], identifying as bisexual, RR = 0.52, 95% CI [0.29, 0.92], and the combination of the two, RR = 0.24, 95% CI [0.07, 0.76] were significantly associated with lower rates of current oral PrEP use. Black bisexual-identifying men who reported sex with men and women were significantly more likely to have discontinued oral PrEP, RR = 2.50, 95% CI [1.14, 5.50], than Black gay-identified men who reported sex with men only. Participants who had not used oral PrEP before reported lower levels of interest in long-acting injectable PrEP than those who were currently using oral PrEP, RR = 0.56, 95% CI [0.40, 0.79]. No other significant differences were found. Overlooking the combination of sexual identity and behavior may mischaracterize PrEP rates and miss uniquely vulnerable subgroups. Black gay and bisexual men who had not used oral PrEP may be particularly disinterested in long-acting injectable PrEP.

Abstract
In 2012, the U.S. FDA approved the first drug for use as HIV Pre-Exposure Prophylaxis (PrEP), which is nearly 99% effective when taken as prescribed. Although the manifest function of PrEP is to prevent HIV infection in the event of exposure, the drug has also had a significant impact on various facets of sexuality. In this review, we focus on research that emerged in the near decade since PrEP's approval, with a specific focus on the ways in which different elements of sex and sexuality have been impacted by gay, bisexual, and other men who have sex with men (GBMSM), cisgender women, and transgender individuals. We highlight evidence showing how PrEP has enhanced sexual self-esteem, improved sexual pleasure, reduced sexual anxiety, and has increased sexual agency for those taking it. For many, PrEP also serves as a gateway to improve routine health and increase sexual health-care utilization. Additionally, we review the question of whether PrEP is associated with increased sexual risk taking (i.e. risk compensation), and note that, although some data are mixed, PrEP is not intended as an intervention to reduce condomless anal sex or STIs: it aims to prevent HIV. Finally, our review highlights that, although the volume of research on PrEP among GBMSM is robust, it is underdeveloped for cisgender women and transgender populations and insufficient for inclusion in such a review for cisgender heterosexual men was. PrEP research with these populations is an important direction for future research. Finally, from 2012 to 2019, a single PrEP formulation and delivery method was FDA approved (oral emtricitabine/tenofovir disoproxil fumarate). As additional drug formulations (ie.g., emtricitabine/tenofovir alafenamide) and delivery methods (e.g., microbiocides, vaginal ring, injectable) come to market, it will be important to examine how these, too, impact the spectrum of sexuality.

Abstract
PURPOSE The incidence of new HIV infections is disproportionately high among Black men who have sex with men (BMSM) in Mississippi. Community-based organizations received funding through the ACCELERATE! initiative to implement interventions aimed at increasing BMSM's access to HIV prevention, treatment and care interventions. APPROACH We conducted a mixed methods evaluation of the ACCELERATE! initiative to assess its impact. We also explored factors that act as barriers to and facilitators of BMSM's engagement in HIV prevention interventions. SETTING Interviews were conducted between July 2018 and February 2020. PARTICIPANTS Thirty-six BMSM and 13 non-grantee key informants who worked in the field of HIV in Mississippi participated. METHOD The qualitative data from the interview transcripts was analyzed using an iterative, inductive coding process. RESULTS We identified 10 key recommendations that were most common across all participants and that were aligned with UNAIDS Global AIDS Strategy strategic priorities. Several recommendations address the reduction of HIV- and LGBT-stigma. Two of the most common recommendations were to increase representation of the target population in health promotion program leadership and to include HIV with other Black health issues in community-based health education programs rather than singling it out. Another recommendation called for programs aimed at addressing underlying factors associated with HIV-risk behaviors, such as mental illness. CONCLUSION Our results indicate that HIV education interventions in the Deep South need to be revitalized to enhance their reach and effectiveness.

Abstract
BACKGROUND Reducing HIV incidence requires addressing persistent racial/ethnic disparities in HIV burden. Our goal was to evaluate preexposure prophylaxis (PrEP) delivery, overall and relative to community need, among 7 clinical sites participating in a health department-led demonstration project to increase PrEP in Baltimore city, MD. METHODS PrEP care continuum stages (screened, indicated, referred, linked, evaluated, prescribed) were examined among HIV-negative individuals receiving services at participating sites between September 30, 2015 and September 29, 2019. Community need was defined using information on new HIV diagnoses (2016-2018). Differences in care continuum progression by demographics/priority population and comparison of demographic compositions between care continuum stages and new HIV diagnoses were examined using modified Poisson regression and χ2 tests, respectively. RESULTS Among 25,886 PrEP-screened individuals, the majority were non-Hispanic (NH) black (81.1%, n = 20,998), cisgender male (61.1%, n = 15,825), and heterosexual (86.7%, n = 22,452). Overall, 31.1% (n = 8063) were PrEP-indicated; among whom, 56.8% (n = 4578), 15.6% (n = 1250), 10.8% (n = 868), and 9.0% (n = 722) were PrEP-referred, linked, evaluated, and prescribed, respectively. Among 2870 men who have sex with men (MSM), 18.7% (n = 538) were PrEP-prescribed. Across all groups, the highest attrition was between PrEP-referred and PrEP-linked. NH-black race (vs. NH-white) was independently associated with lower likelihood of PrEP prescription (aPR, 0.89; 95% confidence interval, 0.81 to 0.98 controlling for age/gender). Relative to the demographic composition of new HIV diagnoses, fewer NH-blacks (80.2% vs. 54.3%) and more NH-whites (10.7% vs. 30.3%) and MSM were PrEP prescribed (55.2% vs. 74.5%). CONCLUSIONS This project showed promise delivering PrEP referrals and prescriptions overall and to MSM. Substantial improvement is needed to improve linkage overall and to decrease disparities in PrEP prescriptions among NH-blacks. Future work should focus on addressing service gaps that hinder PrEP utilization.

Abstract
PURPOSE OF REVIEW Recent HIV outbreaks among people who use drugs (PWUD) necessitate additional HIV prevention tools. Pre-exposure prophylaxis (PrEP) is highly efficacious yet uptake among PWUD remains exceedingly low. To address multilevel, complex barriers to PrEP use among PWUD, a range of intervention strategies are needed. RECENT FINDINGS The literature on interventions to optimize PrEP use among PWUD is nascent, comprising small pilots and demonstration projects in early phases of intervention development. Initial studies suggest that structural, healthcare, interpersonal, and individual-level interventions can improve PrEP use for PWUD, and a number of efficacy trials are underway. Future studies are needed to optimize the use of new PrEP modalities (e.g., injectable PrEP), simultaneously target multilevel challenges to PrEP use, and evaluate the integration of PrEP into other service settings and substance use treatment modalities.

Abstract
OBJECTIVES Gaps between recommended and actual levels of HIV preexposure prophylaxis (PrEP) use remain among MSM. Interventions can address these gaps but it is unknown how public health initiatives should invest prevention funds into these interventions to maximize their population impact. DESIGN We used a stochastic network-based HIV transmission model for MSM in the Atlanta area paired with an economic budget optimization model. METHODS The model simulated MSM participating in up to three real-world PrEP cascade interventions designed to improve initiation, adherence, or persistence. The primary outcome was infections averted over 10 years. The budget optimization model identified the investment combination under different budgets that maximized this outcome, given intervention costs from a payer perspective. RESULTS From the base 15% PrEP coverage level, the three interventions could increase coverage to 27%, resulting in 12.3% of infections averted over 10 years. Uptake of each intervention was interdependent: maximal use of the adherence and persistence interventions depended on new PrEP users generated by the initiation intervention. As the budget increased, optimal investment involved a mixture of the initiation and persistence interventions but not the adherence intervention. If adherence intervention costs were halved, the optimal investment was roughly equal across interventions. CONCLUSION Investments into the PrEP cascade through initiatives should account for the interactions of the interventions as they are collectively deployed. Given current intervention efficacy estimates, the total population impact of each intervention may be improved with greater total budgets or reduced intervention costs.

Abstract
Retention in HIV pre-exposure prophylaxis (PrEP) care is critical for effective PrEP implementation. Few studies have reported long-term lost to follow-up (LTFU) and re-engagement in PrEP care in the United States. Medical record data for all cisgender patients presenting to the major Rhode Island PrEP clinic from 2013 to 2019 were included. LTFU was defined as no PrEP follow-up appointment within 98 days. Re-engagement in care was defined as individuals who were ever LTFU and later attended a follow-up appointment. Recurrent event survival analysis was performed to explore factors associated with PrEP retention over time. Of 654 PrEP patients, the median age was 31 years old [interquartile range (IQR): 25, 43]. The majority were male (96%), White (64%), non-Hispanic (82%), and insured (97%). Overall, 72% patients were ever LTFU and 27% of those ever LTFU re-engaged in care. Female patients were 1.37 times [crude hazard ratio (cHR): 1.37; 95% confidence interval (CI): 0.86-2.18] more likely to be LTFU than male patients, and a 1-year increase in age was associated with a 1% lower hazard of being LTFU (cHR: 0.99; CI: 0.98-0.99). Being either heterosexual (aHR: 2.25, 95% (CI): 1.70-2.99] or bisexual (aHR: 2.35, 95% CI: 1.15-4.82) was associated with a higher hazard of loss to follow-up compared with having same-sex partners only. The majority of PrEP users were LTFU, especially at the first 6 months of PrEP initiation. Although a significant number were re-engaged in care, targeted interventions are needed to improve retention in PrEP care. This study characterized the natural projection of loss to follow-up and re-engagement in HIV PrEP care using a longitudinal clinic cohort data and explored associated factors for guiding future interventions to improve retention in PrEP care.

Abstract
Pre-exposure prophylaxis (PrEP), a highly effective HIV prevention strategy, is currently underutilized by several at-risk groups, including both persons who inject drugs and those who use drugs via other routes. Stimulant use is associated with increased HIV risk due to both sexual and injection risk behaviors. In this study, we examined PrEP awareness and acceptability in persons with biologically confirmed HIV-negative status who use stimulant drugs. We also examined HIV risk behaviors to identify how many participants met behavioral eligibility for PrEP. The sample of 352 participants was 46% female, 87% African American, and 45.69 years old on average. Over half the sample (n = 213) met criteria for PrEP candidacy, but less than 20% had heard of PrEP. Ratings for willingness to take PrEP were high. PrEP candidates reported more frequent and problematic stimulant use relative to non-candidates. Our results show that persons who use stimulants are a high-risk population that could benefit significantly from PrEP. Efforts to increase PrEP awareness among high-risk populations are critical for facilitating PrEP implementation and ensuring effective HIV prevention within these communities.

Abstract
In the United States, HIV infection rate inequities persist, with new infections highest among young, Black men who have sex with men (YBMSM) in the South. We conducted 23 in-depth interviews with YBMSM newly diagnosed with HIV to explore awareness of and barriers to uptake of HIV pre-exposure prophylaxis (PrEP). Participants were recruited from two university-based HIV Clinics in Alabama and were: (1) 16-29 years of age, (2) diagnosed with HIV within the prior 365 days, (3) Black race, (4) self-identified as a cis-gender male reporting sex with men AND (5) did not report prior PrEP use. Interview guides were grounded in Anderson's Behavioral Healthcare Utilization Model (ABM), with embedded constructs from the situated Information, Motivation and Behavioral Skills theoretical framework. Coding was conducted by three independent coders using thematic analysis methods. Participants (N = 23) median age was 24, more than two-thirds reported annual incomes less than $15,000 and the majority (84%) identified as gay. Major themes that emerged as barriers to accessing PrEP included low prioritization and interests in using PrEP; low perceived HIV risk due to feelings of invincibility and trust in sex partners; lack of information about accessing PrEP; negative beliefs around PrEP; and the suggestion to change PrEP messaging from only targeting YBMSM. These findings indicate that there are important missed opportunities for HIV prevention with PrEP among YBMSM in the South. In these high-risk young men, tailored interventions are needed to better inform and frame perceptions around risk, knowledge, access and prioritization of PrEP.

Abstract
Mathematical models of sexually transmitted disease (STI) are increasingly relied on to inform policy, practice, and resource allocation. Because STI transmission requires sexual contact between two or more people, a model's ability to represent the dynamics of sexual partnerships can influence the validity of findings. This ability is to a large extent constrained by the model type, as different modeling frameworks vary in their capability to capture patterns of sexual contact at individual, partnership, and network levels. In this paper, we classify models into three groups: compartmental, individual-based, and statistical network models. For each framework, we describe the basic model structure and discuss key aspects of sexual partnership dynamics: how and with whom partnerships are formed, partnership duration and dissolution, and temporal overlap in partnerships (concurrency). We illustrate the potential implications of accurately accounting for partnership dynamics, but these effects depend on characteristics of both the population and pathogen; the combined impact of these partnership and epidemiologic dynamics can be difficult to predict. While each of the reviewed model frameworks may be appropriate to inform certain research or policy questions, modelers and consumers of models should carefully consider the implications of sexual partnership dynamics for the questions under study.

Abstract
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.

Abstract
BACKGROUND The pre-exposure prophylaxis (PrEP) cascade outlines sequential steps to maximize PrEP's impact and highlights potential intervention targets to improve PrEP implementation. We evaluate the PrEP cascade in the Together 5000 study (T5K). METHODS T5K is an internet-based, US national cohort study of PrEP-eligible men and trans persons who have sex with men who were not taking PrEP at enrollment. Using longitudinal data from baseline (2017-2018) and year 1 follow-up (2018-2019, n = 4229), we evaluated 5 steps of the PrEP cascade-PrEP contemplation: believes they are a good candidate for PrEP; PrEParation: plans to initiate PrEP; PrEP action: speaks to a provider about PrEP; PrEP initiation: receives a prescription for PrEP; and PrEP maintenance: continues to take PrEP. We compared the cascade across geographic region and identified factors associated with gaps in the cascade. RESULTS After 1 year, 1092 (26%) participants had initiated PrEP, 709 (17%) were still using PrEP, and 177 (4%) were no longer clinically indicated for PrEP. Participants in the South and Midwest were less likely to speak to a provider about PrEP or initiate PrEP. Baseline characteristics associated with lower odds of PrEP initiation at year 1 include: not having a college degree; earning <$20,000/year; not having health insurance; having very low food security; and not having a primary care doctor. CONCLUSIONS Lack of health care access is a major barrier to PrEP implementation and may exacerbate disparities in PrEP uptake across geographic regions.

Abstract
BACKGROUND We assessed willingness to use HIV pre-exposure prophylaxis (PrEP) and current PrEP use among gay and bisexual men (GBM) in Australia. METHODS National, online cross-sectional surveys of GBM were conducted in 2013, 2015, 2017, and 2019. Willingness to use PrEP was measured on a previously validated scale. Trends and associations with key measures were analyzed using multivariate logistic regression. RESULTS During 2013-2019, 4908 surveys were completed. Among HIV-negative and untested men not currently using PrEP, willingness to use PrEP increased from 23.0% in 2013 to 36.5% in 2017 (P < 0.001) but then plateaued at 32% in 2019 (P = 0.13). The proportion of current PrEP users increased significantly from 2.5% in 2015 to 38.5% in 2019 (P < 0.001). In 2019, factors independently associated with being a current PrEP user (compared with non-PrEP users who were willing to use PrEP) included having subsidized health care (Medicare), knowing HIV-positive people, being recently diagnosed with an STI other than HIV, having higher numbers of recent male sexual partners, recent condomless sex with casual and regular partners, and frequent PrEP sorting. CONCLUSION Willingness to use PrEP has plateaued as its use has rapidly increased among GBM in Australia. PrEP use is concentrated among more sexually active men with access to subsidized health care. Free or low cost access schemes may facilitate broader access among GBM who want or need PrEP but lack access to subsidized health care.

Abstract
BACKGROUND The global COVID-19 pandemic has the potential to indirectly impact transmission dynamics and prevention of HIV and other sexually transmitted infections (STI). It is unknown what combined impact reductions in sexual activity and interruptions in HIV/STI services will have on HIV/STI epidemic trajectories. METHODS We adapted a model of HIV, gonorrhea, and chlamydia for a population of approximately 103 000 men who have sex with men (MSM) in the Atlanta area. Model scenarios varied the timing, overlap, and relative extent of COVID-19-related sexual distancing and service interruption within 4 service categories (HIV screening, preexposure prophylaxis, antiretroviral therapy, and STI treatment). RESULTS A 50% relative decrease in sexual partnerships and interruption of all clinical services, both lasting 18 months, would generally offset each other for HIV (total 5-year population impact for Atlanta MSM, -227 cases), but have net protective effect for STIs (-23 800 cases). If distancing lasted only 3 months but service interruption lasted 18 months, the total 5-year population impact would be an additional 890 HIV cases and 57 500 STI cases. CONCLUSIONS Immediate action to limit the impact of service interruptions is needed to address the indirect effects of the global COVID-19 pandemic on the HIV/STI epidemic.

Abstract
Men who have sex with men (MSM) in the USA were the first population to be identified with AIDS and continue to be at very high risk of HIV acquisition. We did a systematic literature search to identify the factors that explain the reasons for the ongoing epidemic in this population, using a social-ecological perspective. Common features of the HIV epidemic in American MSM include role versatility and biological, individual, and social and structural factors. The high-prevalence networks of some racial and ethnic minority men are further concentrated because of assortative mixing, adverse life experiences (including high rates of incarceration), and avoidant behaviour because of negative interactions with the health-care system. Young MSM have additional risks for HIV because their impulse control is less developed and they are less familiar with serostatus and other risk mitigation discussions. They might benefit from prevention efforts that use digital technologies, which they often use to meet partners and obtain health-related information. Older MSM remain at risk of HIV and are the largest population of US residents with chronic HIV, requiring culturally responsive programmes that address longer-term comorbidities. Transgender MSM are an understudied population, but emerging data suggest that some are at great risk of HIV and require specifically tailored information on HIV prevention. In the current era of pre-exposure prophylaxis and the undetectable equals untransmittable campaign, training of health-care providers to create culturally competent programmes for all MSM is crucial, since the use of antiretrovirals is foundational to optimising HIV care and prevention. Effective control of the HIV epidemic among all American MSM will require scaling up programmes that address their common vulnerabilities, but are sufficiently nuanced to address the specific sociocultural, structural, and behavioural issues of diverse subgroups.

Abstract
BACKGROUND Sexual network degree, a count of ongoing partnerships, plays a critical role in the transmission dynamics of human immunodeficiency virus and other sexually transmitted infections. Researchers often quantify degree using self-reported cross-sectional data on the day of survey, which may result in bias because of uncertainty about future sexual activity. METHODS We evaluated the bias of a cross-sectional degree measure with a prospective cohort study of men who have sex with men (MSM). At baseline, we asked men about whether recent sexual partnerships were ongoing. We confirmed the true, ongoing status of those partnerships at baseline at follow-up. With logistic regression, we estimated the partnership-level predictors of baseline measure accuracy. With Poisson regression, we estimated the longitudinally confirmed degree as a function of baseline predicted degree. RESULTS Across partnership types, the baseline ongoing status measure was 70% accurate, with higher negative predictive value (91%) than positive predictive value (39%). Partnership exclusivity and racial pairing were associated with higher accuracy. Baseline degree generally overestimated confirmed degree. Bias, or number of ongoing partners different than predicted at baseline, was -0.28 overall, ranging from -1.91 to -0.41 for MSM with any ongoing partnerships at baseline. Comparing MSM of the same baseline degree, the level of bias was stronger for black compared with white MSM, and for younger compared with older MSM. CONCLUSIONS Research studies may overestimate degree when it is quantified cross-sectionally. Adjustment and structured sensitivity analyses may account for bias in studies of human immunodeficiency virus or sexually transmitted infection prevention interventions.

Abstract
While oral pre-exposure prophylaxis (PrEP) has proven efficacious for HIV prevention, consistent use is necessary to achieve its intended impact. We compared effectiveness of enhanced PrEP (enPrEP) adherence support to standard of care (sPrEP) among Black MSM and TGW attending a community clinic in Harlem, NY. EnPrEP included peer navigation, in-person/online support groups, and SMS messages. Self-reported adherence over previous 30 days, collected in quarterly interviews, was defined as ≥ 57%. Crude and adjusted analyses examined factors associated with adherence. A total of 204 participants were enrolled and randomized; 35% were lost to follow-up. PrEP adherence was 30% at 12-months; no intervention effect was observed (p = 0.69). Multivariable regression analysis found that lower adherence was associated with low education and depressive symptoms. We found that an enhanced adherence intervention did not improve PrEP adherence. Findings point to the need for innovative methods to improve PrEP adherence among Black MSM and TGW.Clinical Trial Registration NCT02167386, June 19, 2014.

Abstract
OBJECTIVE We sought to evaluate, which combinations of HIV prevention and care activities would have the greatest impact towards reaching the US Ending the HIV Epidemic (EHE) plan goals of HIV incidence reduction. DESIGN A stochastic network-based HIV transmission model for men who have sex with men (MSM), calibrated to surveillance estimates in the Atlanta area, a focal EHE jurisdiction. METHODS Model scenarios varied HIV screening rates under different assumptions of how HIV-negative MSM would be linked to PrEP initiation, and rates of HIV care linkage and retention for those screening positive. RESULTS A ten-fold relative increase in HIV screening rates (to approximately biannual screening for black and Hispanic MSM and quarterly for white MSM) would lead to 43% of infections averted if integrated with PrEP initiation. Improvements focused only on black MSM would achieve nearly the same outcome (37% of infections averted). Improvements to HIV care retention would avert 41% of infections if retention rates were improved ten-fold. If both screening and retention were jointly improved ten-fold, up to 74% of cumulative infections would be averted. Under this scenario, it would take 4 years to meet the 75% EHE goal and 12 years to meet the 90% goal for Atlanta MSM. CONCLUSION Reaching the EHE 75% incidence reduction goals by their target dates will require immediate and substantial improvements in HIV screening, PrEP, and ART care retention. Meeting these EHE goals in target jurisdictions like Atlanta will be possible only by addressing the HIV service needs of black MSM.

Estimated Number of Men Who Have Sex With Men With Indications for HIV Pre-exposure Prophylaxis in a National Sexual Network Study. J Acquir Immune Defic Syndr 2020; 84:10-17.

Abstract
BACKGROUND A 2015 CDC analysis estimated that 24.7% of sexually active men who have sex with men (MSM) had indications for HIV pre-exposure prophylaxis (PrEP) based on 2014 US Public Health Service (USPHS) clinical practice guidelines. Given that the USPHS revised these guidelines in 2017, updated estimates of the fraction of MSM indicated for PrEP overall and stratified by demographic factors and geography are needed to scale-up PrEP for MSM in the US. METHODS We conducted a national web-based study of 4904 MSM aged 15-65 who had ever had sex with another man between July 2017 and January 2019. We estimated the percentage of HIV-negative, sexually active MSM meeting USPHS indications for PrEP by demographic category. RESULTS Of 3511 sexually active, HIV-negative MSM, 34.0% (95% confidence interval: 32.4 to 35.6) met USPHS indications for PrEP, with percentages consistent across US census region and varying slightly by race/ethnicity (Black: 32.2%, White: 33.7%, Hispanic: 36.4%, Other: 33.6%). Among individuals meeting USPHS PrEP indications, 93.5% reported condomless anal intercourse in the prior 6 months. Among all survey respondents, PrEP eligibility was lowest among non-Hispanic black (18.4%) and younger respondents (15-17: 4.1%; 18-24: 18.1%). CONCLUSIONS Estimated percentages of MSM meeting indications for PrEP exceeded the previous CDC estimate across race/ethnicity, age, and census regions, with one-third of adult, sexually active, HIV-negative MSM exhibiting indications for PrEP. This study suggests, given current guidelines for PrEP indications, that a different fraction of eligible MSM could be receiving PrEP than previously estimated.

Abstract
BACKGROUND The global COVID-19 pandemic has the potential to indirectly impact the transmission dynamics and prevention of HIV and other sexually transmitted infections (STI). Studies have already documented reductions in sexual activity ("sexual distancing") and interruptions in HIV/STI services, but it is unknown what combined impact these two forces will have on HIV/STI epidemic trajectories. METHODS We adapted a network-based model of co-circulating HIV, gonorrhea, and chlamydia for a population of approximately 103,000 men who have sex with men (MSM) in the Atlanta area. Model scenarios varied the timing, overlap, and relative extent of COVID-related sexual distancing in casual and one-time partnership networks and service interruption within four service categories (HIV screening, HIV PrEP, HIV ART, and STI treatment). RESULTS A 50% relative decrease in sexual partnerships and interruption of all clinical services, both lasting 18 months, would generally offset each other for HIV (total 5-year population impact for Atlanta MSM: -227 cases), but have net protective effect for STIs (-23,800 cases). Greater relative reductions and longer durations of service interruption would increase HIV and STI incidence, while greater relative reductions and longer durations of sexual distancing would decrease incidence of both. If distancing lasted only 3 months but service interruption lasted 18 months, the total 5-year population impact would be an additional 890 HIV cases and 57,500 STI cases. CONCLUSIONS The counterbalancing impact of sexual distancing and clinical service interruption depends on the infection and the extent and durability of these COVID-related changes. If sexual behavior rebounds while service interruption persists, we project an excess of hundreds of HIV cases and thousands of STI cases just among Atlanta MSM over the next 5 years. Immediate action to limit the impact of service interruptions is needed to address the indirect effects of the global COVID pandemic on the HIV/STI epidemic.

Abstract
BACKGROUND The US National HIV/AIDS Strategy 2020 calls for increasing access to care, improving outcomes of people living with HIV, and targeting biomedical prevention efforts, including access to pre-exposure prophylaxis (PrEP) in communities where HIV is most heavily concentrated. The cities of Baltimore, Maryland (MD); Washington, DC; and Philadelphia, Pennsylvania (PA) are disproportionately burdened by high rates of new cases of HIV infection, with high prevalence among young Black and Latinx men who have sex with men (YBLMSM) and young Black and Latinx transgender women (YBLTW) aged 15-24 years. OBJECTIVE This study aims (1) to identify and recruit YBLMSM and YBLTW who are at risk or living with HIV in Baltimore, MD; Philadelphia, PA; and Washington, DC, using respondent-driven sampling (RDS) with targeted seed selection, and (2) to assess the efficacy of a coach-based mobile-enhanced intervention (MEI) compared with standard of care (SOC) to increase successful engagement and retention into HIV, PrEP, and substance use treatment care across the HIV care and prevention continua in 3 Mid-Atlantic cities. This paper describes the protocol and progress as of October 20, 2019. METHODS This study uses a multiphase mixed methods design. The first phase is a formative, qualitative research with focus group discussions and key informant interviews. The second phase consists of evaluating the ability of RDS with targeted seed selection. The third phase includes 2 embedded randomized controlled trials (RCTs), where participants complete a baseline sociobehavioral survey, rapid HIV testing, and eligible youth enroll in parallel status-dependent RCTs that randomize the participant to 1 of 2 study arms: MEI with coach or SOC. Participants are asked to complete a web-based survey and provide biologic specimens-HIV-1 RNA (viral load) or HIV-1 antibody test and urine drug screen-at baseline and at 3, 6, and 12 months, and an exit interview at 18 months. RESULTS A formative qualitative research was conducted in February 2017 and May 2018, and this led to further refinement of recruitment and study methods. Aim 1 recruitment began in September 2017 with subsequent enrollment into the RCTs. Recruitment is ongoing with 520 participants screened and 402 (77.3%) enrolled in aim 1 by October 2020. Of these, 159 are enrolled in the 2 randomized trials: 36 (22.6%) HIV-positive not virally suppressed (aim 2) and 123 (77.4%) high-risk HIV-negative (aim 3). CONCLUSIONS This study has the potential to significantly impact the medical and substance use services provided to YBLMSM and YBLTW in the United States by providing rigorous scientific evidence outlining approaches and strategies that improve the uptake and engagement of YBLMSM and YBLTW in the HIV treatment and prevention continuum.

Abstract
BACKGROUND Clinics providing sexual health care pose unique opportunities to implement HIV pre-exposure prophylaxis (PrEP) programs. The PrEP program at New York City's Sexual Health Clinics provides intensive on-site navigation for linkage to PrEP care. We assessed uptake of this intervention. METHODS We categorized men who have sex with men (MSM) without HIV hierarchically as having had (1) HIV post-exposure prophylaxis (PEP) use (past year); or (2) selected sexually transmitted infections (STI) (past year); or (3) HIV-diagnosed sex/needle-sharing partners (past 6 months); or (4) expressed interest in PrEP (day of clinic visit). We constructed PrEP cascades and used multivariable regression to examine acceptance of PrEP navigation, referral to a PrEP provider, linkage (<60 days), and PrEP prescription. RESULTS One thousand three hundred one of 2106 PrEP (62%) patients accepted navigation. Of those, 55% (718/1301) were black or Hispanic MSM. STI and PEP patients had lowest navigation acceptance levels (35%-46%). Of navigated patients, 56% (628/1114) accepted referrals, 46% (288/628) linked to PrEP providers, and 82% (235/288) were prescribed PrEP; overall, 11% of those offered navigation (235/2106) received prescriptions. Navigated MSM with PEP history [adjusted prevalence ratio (aPR) 1.34, 95% confidence interval (CI): 1.16 to 1.56)], previous STI (aPR 1.28, 95% CI: 1.12 to 1.45), or HIV-diagnosed partners (aPR 1.18, 95% CI: 1.01 to 1.37) were more likely than those with PrEP interest to accept referrals. Probability of linkage varied by insurance status; prescription did not vary by patient factors. CONCLUSIONS Although MSM in key priority groups (eg, previous STI) showed low navigation uptake, those who accepted navigation were likely to be referred for PrEP, suggesting a need for expanded up-front engagement.

Abstract
This paper unveils the pathologies that are produced and sustained by the pharmaceutical industry, specifically by Gilead Sciences, Inc. Broadly defined, pathopolitics is the politics of treating and/or reproducing pathologies. This paper examines pathopolitics in the context of PrEP, or pre-exposure prophylaxis, an antiretroviral medicine that prevents HIV transmission. Although Gilead promises to prevent a pathology through PrEP, it reproduces social and biological pathologies by exposing certain people to higher risks of infections and diseases, thus epitomizing the operating logic of the pharmaceutical industry: that life is protected only insofar as it offers surplus economic and social value. This essay raises three fundamental sets of questions: (1) What are the techniques and mechanics of pathopolitics? (2) How does the pharmaceutical industry produce and exploit surplus value? (3) What is the nature of the relationship between the pharmaceutical citizenship and pathopolitics?

Abstract
BACKGROUND It is unknown what levels of preexposure prophylaxis (PrEP) use are needed to reduce racial disparities in HIV incidence among men who have sex with men (MSM). Using an agent-based model, we quantified the impact of achieving PrEP coverage targets grounded in equity on racial disparities in HIV incidence among MSM in an urban setting in the Southeastern United States. METHODS An agent-based model was adapted to simulate HIV transmission in a network of Black/African American and White MSM aged 18-39 years in the Atlanta-Sandy Springs-Roswell metropolitan area over 10 years (2015-2024). Scenarios simulated coverage levels consistent with targets based on the ratio of the number of individuals using PrEP to the number of individuals newly diagnosed in a calendar year (i.e., the 'PrEP-to-need ratio'), ranging from 1 to 10. Incidence rate ratios and differences were calculated as measures of disparities. RESULTS Without PrEP, the model predicted a rate ratio of 3.82 and a rate difference of 4.50 comparing HIV incidence in Black/African American and White MSM, respectively. Decreases in the rate ratio of at least 50% and in the rate difference of at least 75% were observed in all scenarios in which the PrEP-to-need ratio among Black/African American MSM was 10, regardless of the value among White MSM. CONCLUSION Significant increases in PrEP use are needed among Black/African American MSM to reduce racial disparities in HIV incidence. PrEP expansion must be coupled with structural interventions to address vulnerability to HIV infection among Black/African American MSM.
