RESUMEN

CONTEXT: Medicaid expansion has been nationally shown to improve engagement in the human immunodeficiency virus (HIV) treatment and prevention continua, which are vital steps to stopping the HIV epidemic. New HIV infections in the United States are disproportionately concentrated among young Black men who have sex with men (YBMSM). Houston, TX, is the most populous city in the Southern United States with a racially/ethnically diverse population that is located in 1 of 11 US states that have not yet expanded Medicaid coverage as of 2021. METHODS: An agent-based model that incorporated the sexual networks of YBMSM was used to simulate improved antiretroviral treatment and pre-exposure prophylaxis (PrEP) engagement through Medicaid expansion in Houston, TX. Analyses considered the HIV incidence (number of new infections and as a rate metric) among YBMSM over the next 10 years under Medicaid expansion as the primary outcome. Additional scenarios, involving viral suppression and PrEP uptake above the projected levels achieved under Medicaid expansion, were also simulated. RESULTS: The baseline model projected an HIV incidence rate of 4.96 per 100 person years (py) and about 368 new annual HIV infections in the 10th year. Improved HIV treatment and prevention continua engagement under Medicaid expansion resulted in a 14.9% decline in the number of annual new HIV infections in the 10th year. Increasing viral suppression by an additional 15% and PrEP uptake by 30% resulted in a 44.0% decline in new HIV infections in the 10th year, and a 27.1% decline in cumulative infections across the 10 years of the simulated intervention. FINDINGS: Simulation results indicate that Medicaid expansion has the potential to reduce HIV incidence among YBMSM in Houston. Achieving HIV elimination objectives, however, might require additional effective measures to increase antiretroviral treatment and PrEP uptake beyond the projected improvements under expanded Medicaid.

RESUMEN

Black men who have sex with men (BMSM) and transgender women (BTW) are disproportionately affected by incarceration and HIV. We assessed factors associated with HIV testing and viral suppression among 176 incarcerated BMSM and BTW in Chicago, IL; Los Angeles, CA; and Houston, TX. In multivariable logistic regression, having a sexual orientation of bisexual, heterosexual, or other vs. gay or same-gender loving was associated with higher odds of testing in custody (aOR 8.97; 95% CI 1.95 - 41.24). Binge drinking (aOR 0.19; 95% CI 0.04 - 0.92) and being unemployed prior to incarceration (aOR 0.03; 95% CI 0.00 - 0.23) were associated with lower odds of testing; participants in Los Angeles were also more likely to be tested than those in Chicago. Being housed in protective custody (aOR 3.12; 95% CI 1.09-9.59) and having a prescription for ART prior to incarceration (aOR 2.58; 95% CI 1.01-6.73) were associated with higher odds of viral suppression when adjusted for site and duration of incarceration, though the associations were not statistically significant in the full multivariable model. Future research should examine structural and process level factors that impact engagement in HIV testing and treatment among detained BMSM and BTW.

RESUMEN

BACKGROUND: Expanding pre-exposure prophylaxis (PrEP) among transgender women in the United States is an important strategy to meet national HIV prevention goals, however self-reported use of PrEP is low in this group. METHODS: This study reports the findings of a cross-sectional analysis of the relationship of barriers as well as facilitators to recent PrEP use among transgender women enrolled in an evaluation of the TransLife Care project (Chicago, Illinois), a structural intervention designed to meet basic needs. We computed multivariable prevalence ratios for barriers, facilitators and recent PrEP use, controlling for demographics. RESULTS: Findings suggest that psychosocial and structural barriers, including moderate/high alcohol use, stimulant use, and history of incarceration were all positively associated with recent PrEP use among urban transgender women. In addition, a psychosocial facilitator, gender affirmation, was positively associated with recent PrEP use, while, while collective self-esteem, a was negatively associated with it. Finally, common indications for PrEP have high sensitivity, but low specificity and predictive value for identifying those on PrEP. CONCLUSION: We conclude that despite a large gap in PrEP use among those with indications, individuals experiencing psychosocial and structural barriers are more likely to use PrEP, and facilitators, such as psychological sense of affirmed gender may support its use.

RESUMEN

The TransLife Care (TLC) project was developed to address the structural factors that act as barriers to HIV care among transgender women of color. The purpose of this study was to evaluate the feasibility and initial efficacy of the TLC project; primary HIV care outcomes included linkage to HIV care, engagement in care, retention in care, use of ART and viral suppression among N = 120 participants. In multivariable analysis, receipt of the intervention (versus none), was associated with any HIV care visit (aOR 2.05; 95% CI 1.25-3.37; p = 0.005), more total HIV care visits (aRR 1.45; 95% CI 1.09-1.94; p = 0.011), being retained in care (aOR 1.58; 95% CI 1.03-2.44; p = 0.038), and having a viral load test done (aOR 1.95; 95% CI 1.23-3.09; p = 0.004). We conclude that a structural intervention, designed and delivered by the focus population, that directly addresses social determinants, is feasible and efficacious to promote HIV care engagement among transgender women of color.


RESUMEN: El proyecto TransLife Care (TLC) se desarrolló para abordar los factores estructurales que actúan como barreras para la atención médica del VIH entre las mujeres transgénero de color. El propósito de este estudio fue evaluar la viabilidad y la eficacia inicial del proyecto TLC; los resultados primarios de la atención médica del VIH incluyeron el vínculo con la atención médica del VIH, la retención en la atención médica, el uso de ART y la supresión viral entre N = 120 participantes. En el análisis multivariable, la recepción de la intervención (versus ninguna) se asoció con la participación en la atención médica (aOR 2.05, IC 95% 1.25­3.37, p = 0.005), más visitas totales al VIH (aRR 1.45, IC 95% 1.09­1.94, p = 0.011), se mantuvo en la atención médica (aOR 1.58; IC 95%: 1.03 - 2.44; p = 0.038) y se realizó una prueba de carga viral (aOR 1.95; IC 95%: 1.23 - 3.09; p = 0.004). Concluimos que una intervención estructural, diseñada y ejecutada por la población de enfoque, que aborda directamente los determinantes sociales, es factible y eficaz para promover el compromiso de la atención del VIH entre las mujeres transgénero de color.

RESUMEN

The House and Ball Community (HBC), a tight-knit social and cultural network comprised primarily of Black sexual and gender minorities (SGM), offers unique opportunities for HIV prevention that leverage naturally occurring social support networks. However, experiences of socioeconomic marginalization, stigma, violence, and trauma may impede HIV prevention efforts. This study analyzed data from 551 Black SGM recruited at HBC events in 2 cities over 24 months. Logistic regression with generalized estimating equations examined associations between socio-structural stressors, mental health, substance use, and sexual behavior among HBC participants. Findings indicated high prevalence of depressive symptoms, history of trauma, intimate partner violence, and substance use, and significant associations between socioeconomic marginalization and depressive symptoms, substance use, and condomless anal sex. Future research is needed to better elucidate the temporal relationships between socioeconomic marginalization, mental health and substance use, and HIV transmission dynamics. Results highlight a need for integration of mental health services, substance use treatment, and HIV prevention for this community.

RESUMEN

Transgender women are disproportionately affected by HIV and experiences of social adversity that may interfere with engagement in care and viral suppression. We used latent class analysis to examine patterns of social adversity and their impact on HIV care continuum outcomes in an urban sample of transgender women of color. Participants (n = 224) were median age 29 and 86% non-Hispanic Black. Lack of resources, unemployment, and housing instability were reported by over 50%, and 41% reported history of incarceration. Latent class analysis identified 2 distinct classes representing higher and lower levels of social adversity. In latent class regression, membership in the higher social adversity class was associated with statistically significantly lower odds of viral suppression and HIV care engagement in univariate analysis; when adjusted for age, race, and recruitment site the association remained statistically significant for viral suppression (aOR 0.38, 95% CI 0.18-0.79; chi-square = 6.681, d.f. = 1, p = 0.010), though not for HIV care engagement. Our findings highlight the impact of socio-structural barriers on engagement in the HIV care continuum among transgender women.


RESUMEN: Las mujeres transgénero son desproporcionadamente afectadas por el VIH y las experiencias de adversidad social que pueden interferir con la participación en la atención medica y la supresión viral. Utilizamos un análisis de clase latente para examinar los patrones de adversidad social y su impacto en los resultados continuos de la atención medica del VIH en una muestra urbana de mujeres transgénero de color. Los participantes (n = 224) tenían una mediana de edad de 29 años y 86% negros no hispanos. La falta de recursos, el desempleo y la inestabilidad de la vivienda fueron reportados en más del 50%, y el 41% reportó antecedentes de encarcelamiento. El análisis de clase latente identificó 2 clases distintas que representan niveles más altos y más bajos de adversidad social. En la regresión de clase latente, la pertenencia a la clase de mayor adversidad social se asoció con probabilidades estadísticamente significante más bajas de supresión viral y participación en la atención medica del VIH en el análisis univariante; cuando se ajustó por edad, raza y sitio de reclutamiento, la asociación siguió siendo estadísticamente significativa para la supresión viral (aOR 0.38, IC 95% 0.18­0.79; chi-cuadrado = 6.681, df = 1, p = 0.010), aunque no para la participación en la atención medica del VIH. Nuestros hallazgos destacan el impacto de las barreras socioestructurales en la participación en el continuo de atención medica del VIH entre las mujeres transgénero.

RESUMEN

Black men who have sex with men (MSM) and transgender women are disproportionately affected by criminal justice involvement (CJI) and HIV. This study recruited 618 young Black MSM and transgender women in Chicago, IL, using respondent-driven sampling between 2013 and 2014. Random effects logistic regression evaluated predictors of incident CJI over 18 months of follow-up. Controlling for respondent age, gender and sexual identity, spirituality (aOR 0.56, 95% CI 0.33-0.96), and presence of a mother figure (aOR 0.41, 95% CI 0.19-0.89) were protective against CJI. Economic hardship (financial or residential instability vs. neither aOR 2.23, 95% CI 1.10-4.51), two or more past episodes of CJI vs. none (aOR 2.66, 95% CI 1.40-5.66), and substance use (marijuana use vs. none aOR 2.79, 95% CI 1.23-6.34; other drug use vs. none aOR 4.49, 95% CI 1.66-12.16) were associated with CJI during follow-up. Research to identify and leverage resilience factors that can buffer the effects of socioeconomic marginalization may increase the effectiveness of interventions to address the socio-structural factors that increase the risk for CJI among Black MSM and transgender women. Given the intersection of incarceration, HIV and other STIs, and socio-structural stressors, criminal justice settings are important venues for interventions to reduce health inequities in these populations.

RESUMEN

INTRODUCTION: Youth of color (e.g., Black/African American and Latinx/Hispanic) are overrepresented in the juvenile justice system and experience greater health disparities compared to non-Hispanic White youth. Ethnic/racial discrimination (ERD) is a risk marker for poor mental health and behavioral outcomes among youth of color, and traumatic stress and emotion dysregulation have been implicated in these pathways. Despite the relevance of these factors for justice-involved youth of color, understanding of their interrelations within this demographic is lacking. METHODS: Participants were 173 recently arrested adolescents (86% African American; 45% girls; ages 13-18) on probation in a large Midwest city in the United States. Participants completed surveys assessing ERD, traumatic stress, emotion dysregulation, internalizing symptoms, and externalizing behaviors. Using linear regression and path analysis, this study tested the cross-sectional links among two types of ERD (i.e., interpersonal experiences and perceptions of group experiences), traumatic stress symptoms, emotion dysregulation, and internalizing symptoms and externalizing behaviors. RESULTS: Interpersonal ERD (e.g., hearing racial insults) was associated with increased internalizing symptoms and externalizing behaviors; for internalizing symptoms, the relation was stronger for girls than boys. Gender differences were partially accounted for by traumatic stress symptoms and emotion dysregulation. CONCLUSIONS: This study offers new insights into ERD experiences among juvenile justice-involved youth of color, gender differences in ethnic/racial discrimination experiences, and the potential value of gender-sensitive and culturally responsive programming in strengthening youths' ability to cope with ERD.

RESUMEN

BACKGROUND: Relatively high plasma levels of soluble urokinase-type plasminogen activator receptor (suPAR) have been associated with focal segmental glomerulosclerosis and poor clinical outcomes in patients with various conditions. It is unknown whether elevated suPAR levels in patients with normal kidney function are associated with future decline in the estimated glomerular filtration rate (eGFR) and with incident chronic kidney disease. METHODS: We measured plasma suPAR levels in 3683 persons enrolled in the Emory Cardiovascular Biobank (mean age, 63 years; 65% men; median suPAR level, 3040 pg per milliliter) and determined renal function at enrollment and at subsequent visits in 2292 persons. The relationship between suPAR levels and the eGFR at baseline, the change in the eGFR over time, and the development of chronic kidney disease (eGFR <60 ml per minute per 1.73 m(2) of body-surface area) were analyzed with the use of linear mixed models and Cox regression after adjustment for demographic and clinical variables. RESULTS: A higher suPAR level at baseline was associated with a greater decline in the eGFR during follow-up; the annual change in the eGFR was -0.9 ml per minute per 1.73 m(2) among participants in the lowest quartile of suPAR levels as compared with -4.2 ml per minute per 1.73 m(2) among participants in the highest quartile (P<0.001). The 921 participants with a normal eGFR (≥ 90 ml per minute per 1.73 m(2)) at baseline had the largest suPAR-related decline in the eGFR. In 1335 participants with a baseline eGFR of at least 60 ml per minute per 1.73 m(2), the risk of progression to chronic kidney disease in the highest quartile of suPAR levels was 3.13 times as high (95% confidence interval, 2.11 to 4.65) as that in the lowest quartile. CONCLUSIONS: An elevated level of suPAR was independently associated with incident chronic kidney disease and an accelerated decline in the eGFR in the groups studied.

RESUMEN

Young people in the USA who inject drugs, particularly those at a risk of residence instability, experience the highest incidence of hepatitis C (HCV) infections. This study examined associations between geographic mobility patterns and sociodemographic, behavioral, and social network characteristics of 164 young (ages 18-30) persons who inject drugs (PWID). We identified a potential bridge sub-population who reported residence in both urban and suburban areas in the past year (crossover transients) and higher-risk behaviors (receptive syringe sharing, multiple sex partners) compared to their residentially localized counterparts. Because they link suburban and urban networks, crossover transients may facilitate transmission of HIV and HCV between higher and lower prevalence areas. Interventions should address risk associated with residential instability, particularly among PWID who travel between urban and suburban areas.

RESUMEN

Persons who inject drugs (PWID) may be at risk of acquiring HIV and sexually transmitted infections (STIs) from risky sexual practices and elevated disease prevalence within their drug injection and sexual networks. We conducted a personal (egocentric) network study of young PWID (aged 18-30) from the Chicago metropolitan area. Logistic regression with generalized estimating equations evaluated associations between individual and network factors and sexual behaviors. Of 162 participants, 116 (71.6 %) were non-Hispanic White and 135 reported on 314 sexual network members. Multiplexity-having network members with overlapping roles as injection and sexual partners-was associated with more condomless vaginal sex (aOR 5.55; 95 % CI 1.62-19.0) and anal sex (aOR 6.79; 95 % CI 2.49-18.5) and less exchange sex among women (aOR 0.12; 95 % CI 0.03-0.40), adjusting for sociodemographic and sexual network characteristics. The contribution of individual and sexual network factors to HIV/STI transmission among young PWID warrants further research.

RESUMEN

Pre-exposure prophylaxis (PrEP) is efficacious to prevent HIV infection, however, uptake among young men who have sex with men (YMSM) is relatively low. The purpose of this study was to describe PrEP use and related factors in a representative sample of YMSM in two cities, Chicago and Houston. YMSM, ages 16-29, were recruited via respondent-driven sampling (RDS) from 2014 to 2016. Correlates of PrEP uptake were assessed in weighted multivariable logistic regression models. A total of 12.2% of participants (of 394) reported ever taking PrEP; Black YMSM had the lowest rates of uptake (4.7%) and Whites the highest (29.5%). In a multivariable regression model, having an HIV positive sex partner, reporting recent group sex, peer network size, and city (Chicago) were significantly and positively associated with use of PrEP, while Black race was negatively associated with it. Given evidence of racial/ethnic disparities in PrEP uptake in this study, further research is needed to identify potential mechanisms of action and points of intervention.

RESUMEN

Younger Black men who have sex with men (YBMSM) have the highest rates of HIV incidence in the U.S. and are also exposed to high life stressors (e.g., unemployment, incarceration, and exposure to communality). This study assessed whether life stressors were related to drug use and sexual risk behaviors among a representative sample of YBMSM. The South Side of Chicago and selected adjacent suburbs represents the most populous contiguous Black community in the U.S. Over 10% of the estimated YBMSM population in this geographic region were sampled. Major findings indicated that higher life stress was significantly associated with greater odds of transactional sex (aOR = 2.19; 95% CI 1.09-4.39), substance use with sex with male and transgender partners (aOR = 1.62; 95% CI 1.09-2.39), marijuana (aOR = 2.65; 95% CI 1.43-4.90), crack/cocaine (aOR = 3.21; 95% CI 1.16-8.88), and prescription opioid use (aOR = 3.12; 95% CI 1.37-7.13). HIV approaches which focus on environmental stressors and employ a stress and coping framework may support the reduction of drug and sexual risk behaviors among YBMSM. Cognitive and social support approaches might be especially useful in this regard.

RESUMEN

POWER is a theory-based, on-line HIV prevention intervention developed specifically for Black men who have sex with men and women (BMSMW), an understudied group significantly impacted by HIV. To test its efficacy, we recruited 224 BMSMW using chain referral methods and randomly assigned 108 to POWER and 103 to a health information comparison condition. Three months after the intervention, participants assigned to POWER had lower odds of reporting any condomless vaginal or condomless anal intercourse (CVAI) compared to those in the comparison group (aOR = 0.49; 95 % CI 0.25-0.98; p = 0.044). The intervention was associated with significantly lower odds of condomless anal intercourse with male partners (aOR = 0.55; 95 % CI 0.34-0.91; p = 0.020) but not with female partners and serodiscordant sex with male partners but not with female partners. Future studies are needed to replicate these findings in larger and more diverse samples of BMSMW and to understand the underlying mechanisms through which intervention efficacy was achieved.

RESUMEN

Black young men who have sex with men (BYMSM) are the group most disproportionately impacted by HIV in the USA and most in need of efficacious interventions to address community-level factors that increase their vulnerability to HIV. The House Ball Community (HBC) is a distinct social network within the larger BYMSM community that may be particularly vulnerable to social norms and stigma around HIV. This study tailored an evidence-based, community-level popular opinion leader (OL) intervention for use within the HBC. The intervention, called Promoting Ovahness through Safer Sex Education (POSSE), was then piloted to evaluate feasibility, acceptability, and preliminary efficacy. Recruiting OLs from the community and training them to deliver risk reduction messages were found to be feasible and highly acceptable. Community-level surveys (n = 406) were completed over five waves of data collection. Overall exposure to the intervention increased across waves. Statistically significant (p < .05) declines were observed for multiple sexual partners, condomless anal intercourse with any male partners, and with male partners of unknown HIV status. HIV stigma declined as well, but the trend was not statistically significant.

RESUMEN

An exigent need exists for HIV prevention intervention research targeting young men who have sex with men (MSM)-a group of young adults that, despite composing the highest and most racially disproportionate rates of HIV incidence, have been least often the focus of behavioral intervention research. This pilot study tested a group-based HIV primary prevention intervention for young MSM to evaluate its initial efficacy, feasibility, and acceptability. Participants were randomized (N = 101; aged 16-20 years) to one of two group-level, HIV and STI education programs: controls participated in a non-interactive, lecture-based program, while intervention participants took part in a highly interactive program tailored to young MSM aged 16-20. Sexual risk and social cognitive outcomes were assessed at baseline, 6-, and 12-weeks post-intervention. Over the entire follow-up period, intervention participants were less likely than controls to engage in any sexual behavior while under the influence of substances (p < .05), and a decreasing trend in unprotected anal sex while under the influence of substances was also observed in this group (p = .08). Follow-up differences between groups on social cognitive outcomes favored the intervention group, though these differences were non-significant. Acceptability ratings were modest. A 6-session behavioral intervention tailored to young MSM, aged 16-20, is feasible, acceptable, and demonstrates evidence of preliminary efficacy in reducing sexual risk, specifically sexual risk while under the influence of substances.

RESUMEN

BACKGROUND: Lesbian women may perceive themselves to be at lower risk for sexually transmitted infections (STIs) and use reproductive health care at lower rates compared with heterosexual women. Therefore, STIs in sexual minority women may go undetected. The prevalence and risk factors of urogenital STIs in women of different sexual orientations were investigated. METHODS: This is a cross-sectional study of women attending the STI clinic of Howard Brown Health Center in Chicago, Illinois. Women were eligible for inclusion in this study if they reported a sexual identity and were screened for urogenital gonorrhea (GC)/chlamydia (CT) in the clinic between January 2008 and December 2011. RESULTS: Among the 669 women studied, the urogenital prevalence of GC was 1.5% and that of CT was 5.2%. Gonorrhea and CT were only diagnosed in women with recent male sex partners, but sexual identity was not necessarily consistent with sexual partner sex, and women of all sexual orientations were diagnosed as having STIs. Bisexual and heterosexual women had similar diagnosis and STI history rates, whereas lesbian women had a significantly lower history of STIs. Bisexual women had more sex partners than heterosexual or lesbian women, and their partners were less likely to be monogamous. Compared with heterosexual women, sexual minority women had twice the odds of drug use in the last year. CONCLUSIONS: Chlamydia and GC were diagnosed in sexual minority women, and several cases would have been missed if lesbian women were not tested for STIs. High rates of substance use among sexual minority women highlight the need for targeted interventions.

RESUMEN

BACKGROUND: Reverse sequence screening for syphilis, in which an automatable treponemal assay (enzyme immunoassay [EIA]/chemiluminescence assay [CIA]) is performed first and followed by a nontreponemal test for reactive specimens, has been used increasingly in the United States. The EIA is objective, efficient, and believed to be more sensitive than the rapid plasma reagin (RPR) because treponemal antibodies appear before nontreponemal antibodies. We sought to compare the sensitivity of a commonly used EIA, the Trep-Sure EIA (TS-EIA), to the RPR in cases of suspected primary syphilis infection in our clinic. METHODS: A retrospective medical record review of patients with sexually transmitted infection clinic visits from January 2009 to December 2011 was conducted, and 52 patients met the following inclusion criteria: suspected primary syphilis symptoms, at least 1 positive syphilis test result at visit, and no history of syphilis. Sensitivity analyses compared the TS-EIA and RPR, using the reference standard of concordantly positive/reactive TS-EIA/RPR or positive fluorescent treponemal antibody absorption test (FTA-ABS) result. We considered equivocal TS-EIA results to be positive for sensitivity calculations because such results typically reflex to additional testing and therefore may still result in identifying new infections. RESULTS: Twenty-eight (53.8%) of the 52 patients had a positive or equivocal TS-EIA. Twenty-five (89.3%) of those were RPR reactive; the remaining 3 (10.7%) were RPR nonreactive, FTA-ABS positive. Forty patients (76.9%) had a positive RPR, including 15 patients (37.5%) with negative TS-EIA results; all 15 were FTA-ABS positive. Nine additional patients were TS-EIA negative and RPR nonreactive but had a positive FTA-ABS result. The RPR was significantly more sensitive than the EIA (76.9% vs. 53.8%, P = 0.005). Trep-Sure EIA positivity was also significantly associated with higher median RPR titer (P = 0.011). CONCLUSIONS: Use of the TS-EIA may result in underdetection of primary syphilis compared with the RPR. Further evaluation of the sensitivity of the TS-EIA in high-morbidity settings is warranted before the adoption of reverse sequence screening algorithms.

RESUMEN

Exposure to community violence and HIV sexual risks are two major public health concerns among youth. This study tests various pathways linking exposure to community violence and sexual behaviors among African American adolescents. Using a sample of 563 (61% females) African American youth attending high school we examined whether problematic psychological symptoms, low school engagement, and/or negative perceptions of peer norms about safer sex functioned as pathways linking exposure to community violence and sexual behaviors. Major findings indicated that, for boys, the relationship between exposure to community violence and sexual début and sexual risk behaviors were linked by aggression. In addition, the relationship between exposure to community violence and sexual risk behaviors were linked by negative perceptions of peer attitudes about safer sex. For girls, the relationship between exposure to community violence and sexual début was linked by aggression and negative perceptions of peer attitudes about safer sex. These findings provide support for pathways linking exposure to community violence to sexual behaviors.

RESUMEN

Transgender women are disproportionately impacted by HIV infection. We report herein the findings of a pre-post evaluation of the TransLife Care (TLC) project in Chicago, Illinois, on behaviors associated with HIV transmission among transgender women. Participants who received any TLC component versus those who did not were compared using mixed-effects logistic regression with random intercepts across follow-up time points. Ninety-seven participants aged 18 to 59 (median age 24) enrolled; 76.3% were transgender women of color. There was a decrease in condomless sex without consistent PrEP use at 8 months, which was not significantly different between those who did and did not receive the TLC intervention, controlling for calendar time. Evidence does not indicate that the TLC reduces condomless sex without PrEP protection among urban transgender women. However, given the preponderance of evidence of the influence of structural barriers on condomless sex, future research should continue to test the efficacy of structural interventions.
