Decreased Anogenital Gonorrhea and Chlamydia in Transgender and Gender Diverse Primary Care Patients Receiving Gender-Affirming Hormone Therapy.

BACKGROUND: Transgender and gender diverse (TGD) adults in the U.S. experience health disparities, including in anogenital sexually transmitted infections (STI). Gender-affirming hormone therapy (GAHT) is known to be medically necessary and improve health. Few studies have assessed the effect of GAHT on STI diagnoses. OBJECTIVE: To evaluate the effect of GAHT delivered in primary care as an intervention to improve STI outcomes for TGD adults. DESIGN: LEGACY is a longitudinal, multisite cohort study of adult TGD primary care patients from two federally qualified community health centers in Boston, MA, and New York, NY. PARTICIPANTS: Electronic health record data for eligible adult TGD patients contributed to the LEGACY research data warehouse (RDW). A total of 6330 LEGACY RDW patients were followed from 2016 to 2019, with 2555 patients providing STI testing data. MAIN MEASURES: GAHT exposure was being prescribed hormones, and the clinical outcome was anogenital gonorrhea or chlamydia diagnoses. Log-Poisson generalized estimating equations assessed the effect of prescription GAHT on primary outcomes, adjusting for age, race, ethnicity, gender identity, poverty level, health insurance, clinical site, and cohort years. KEY RESULTS: The median age was 28 years (IQR = 13); the racial breakdown was 20.4% Black, 8.1% Multiracial, 6.9% Asian/Pacific Islander, 1.8% Other; 62.8% White; 21.3% Hispanic/Latinx; 47.0% were assigned female at birth, and 16.0% identified as nonbinary. 86.3% were prescribed hormones. Among those tested, the percentage of patients with a positive anogenital STI diagnosis ranged annually from 10.0 to 12.5% between 2016 and 2019. GAHT prescription was associated with a significant reduction in the risk of anogenital STI diagnosis (aRR = 0.75; 95% CI = 0.59-0.96) over follow-up. CONCLUSIONS: GAHT delivered in primary care was associated with less STI morbidity in this TGD cohort over follow-up. Patients may benefit from individualized and tailored clinical care alongside GAHT to optimize STI outcomes.

"Focus more on what's right instead of what's wrong:" research priorities identified by a sample of transgender and gender diverse community health center patients.

BACKGROUND: Transgender and gender diverse (TGD) individuals disproportionately experience disparate health outcomes compared to their cisgender peers. This study aimed to collect qualitative data from a sample of TGD community health center patients on health research priorities to inform future TGD-centered research in the field of TGD health. METHODS: Between September-November of 2018, four focus groups (two groups in Boston MA, two in New York NY; n = 28 individuals) were held to evaluate community-identified TGD health research priorities with a sample of patients from two community health centers. Thematic analyses were conducted and restricted to social factors impacting health. Findings were incorporated into the development of The LEGACY Project, a longitudinal cohort of TGD patients, assessing the impact of gender-affirming care on health outcomes. RESULTS: Cross-cutting themes about TGD research priorities pertaining to social factors and health included: (1) Embodiment: understanding and investigating the complex and intersectional lived experiences of TGD individuals; (2) Social determinants of health: the impact of structural and interpersonal stigma on TGD health; and (3) Resiliency and health promoting factors: the need to expand public health research beyond disparities to assess resiliency and health promotion in TGD communities. CONCLUSIONS: Participants identified investigating the impact of social influences on health as a research priority for TGD patients. Recalibrating field norms from individual researcher priorities to TGD population-driven research will help ensure investigators address topics that may otherwise be missed or overlooked and may optimize the reach and impact of research in TGD health.

Patient-centered practices for engaging transgender and gender diverse patients in clinical research studies.

BACKGROUND: The purpose of this formative study was to assess barriers and facilitators to participation of transgender and gender diverse (TGD) patients in clinical research to solicit specific feedback on perceived acceptability and feasibility of research methods to inform creation of a multisite longitudinal cohort of primary care patients engaged in care at two community health centers. METHOD: Between September-November 2018, four focus groups (FGs) were convened at two community health centers in Boston, MA and New York, NY (N = 28 participants across all 4 groups; 11 in Boston and 17 in New York). FG guides asked about patient outreach, acceptability of study methods and measures, and ideas for study retention. FGs were facilitated by TGD study staff, lasted approximately 90 min in duration, were audio recorded, and then transcribed verbatim by a professional transcription service. Thematic analyses were conducted by two independent analysts applying a constant comparison method. Consistency and consensus were achieved across code creation and application aided by Dedoose software. RESULTS: Participants were a mean age of 33.9 years (SD 12.3; Range 18-66). Participants varied in gender identity with 4 (14.3%) men, 3 (10.7%) women, 8 (28.6%) transgender men, 10 (35.7%) transgender women, and 3 (10.7%) nonbinary. Eight (26.6%) were Latinx, 5 (17.9%) Black, 3 (10.7%) Asian, 3 (10.7%) another race, and 5 (17.9%) multiracial. Motivators and facilitators to participation were: research creating community, research led by TGD staff, compensation, research integrated into healthcare, research applicable to TGD and non-TGD people, and research helping TGD communities. Barriers were: being research/healthcare averse, not identifying as TGD, overlooking questioning individuals, research coming from a 'cisgender lens", distrust of how the research will be used, research not being accessible to TGD people, and research being exploitative. CONCLUSION: Though similarities emerged between the perspectives of TGD people and research citing perspectives of other underserved populations, there are barriers and facilitators to research which are unique to TGD populations. It is important for TGD people to be involved as collaborators in all aspects of research that concerns them.

Gender Non-affirmation from Cisgender Male Partners: Development and Validation of a Brief Stigma Scale for HIV Research with Transgender Men Who Have Sex with Men (Trans MSM).

Some transgender men who have sex with men (trans MSM) are vulnerable to HIV infection and face stigma from sexual partners. We evaluated a brief 4-item measure of gender non-affirmation from cisgender male partners. A non-probability sample of American trans MSM (n = 843) reporting past 6-month sexual contact with a cisgender male completed a cross-sectional survey. Psychometric analyses assessed the scale and modeled HIV risk associations. Overall, 78% experienced past 6-month gender non-affirmation from cisgender male partners. The scale demonstrated good reliability (α = 0.78). Convergent validity was supported in associations with psychological distress and anxiety (p < 0.05). Lower frequency of cisgender male partner stigma was associated with increased odds of past 6-month HIV testing and decreased odds of past 6-month condomless receptive sex (all p < 0.01). The gender non-affirmation from cisgender male sexual partners scale found negative associations with protective health behaviors and can be used to better understand the context of trans MSM risk behavior.

Exploring gender euphoria in a sample of transgender and gender diverse patients at two U.S. urban community health centers.

Transgender and gender diverse (TGD) people are affected by mental health inequities. Gender euphoria-positive emotions or joy in gender-may be associated with positive mental health. Between February 2019-July 2021, we surveyed 2,165 adult TGD patients (median age = 28 years; 29.2 % people of color; 29.6 % nonbinary; 81.0 % taking hormones) evaluating gender euphoria and mental health. Overall, 35.0 % self-reported gender euphoria, 50.9 % gender dysphoria, 23.5 % alcohol misuse, and 44.5 % resilience. Gender euphoria differed by race, gender, insurance, and hormone use, and was associated with reduced gender dysphoria (adjusted Odds Ratio[aOR] = 0.58; 95 % confidence interval [95 %CI] = 0.47-0.72) and alcohol misuse (aOR = 0.75; 95 %CI = 0.60-0.95), and increased resilience (aOR = 1.31; 95 %CI = 1.07-1.61). The construct of gender euphoria may be a promising mental health target.

The Pre-Exposure Prophylaxis Cascade in At-Risk Transgender Men Who Have Sex with Men in the United States.

Purpose: This analysis was designed to characterize the pre-exposure prophylaxis (PrEP) cascade in a U.S. national sample of transgender men and trans masculine adults who have sex with cisgender men (trans MSM) at-risk for HIV acquisition. Methods: From November to December 2017, 843 HIV-negative trans MSM self-reporting past-6-month receptive sex with a cisgender man were recruited via peer referrals, dating apps, listservs, and social media. A computer-assisted self-interview assessed demographics, health care, and the PrEP cascade. Descriptive statistics and multivariable regression models evaluated factors associated with PrEP uptake and persistence. Results: Mean age was 28.1 years (standard deviation = 7.1); 4.8% were Black, 21.7% Latinx, and 25.6% another race/ethnicity. A total of 84.1% had heard of PrEP, with 67.3% reporting interest. More than half (55.2%) were PrEP indicated, of which 50.8% were PrEP naive. Approximately 1/4 (28.0%) reported PrEP use, of which 65.3% were PrEP persistent. PrEP modality preferences were injectable (51.2%), daily oral pill (22.1%), and anal gel/lube (14.6%). Reasons for PrEP noninterest were no HIV risk (68.5%), cost (24.2%), and side effects (20.1%). Surgical gender affirmation, no health care discrimination, and social media as a primary health information source were associated with increased odds of PrEP uptake and persistence (all p < 0.05). PrEP adherence difficulties were reported by 52.6%, due to busy/inconsistent schedule (53.1%), side effects (27.4%), and too many medical visits (11.6%). Conclusion: PrEP uptake was modest among the trans MSM sampled, given prevalent HIV risk behaviors. The limited PrEP uptake in at-risk trans MSM suggests the need to develop culturally tailored community education and interventions.

Longitudinal Cohort Study of Gender Affirmation and HIV-Related Health in Transgender and Gender Diverse Adults: The LEGACY Project Protocol.

BACKGROUND: Transgender and gender diverse (TGD) adults in the United States experience health disparities, especially in HIV infection. Medical gender affirmation (eg, hormone therapy and gender-affirming surgeries) is known to be medically necessary and to improve some health conditions. To our knowledge, however, no studies have assessed the effects of gender-affirming medical care on HIV-related outcomes. OBJECTIVE: This study aims to evaluate the effects of medical gender affirmation on HIV-related outcomes among TGD primary care patients. Secondary objectives include characterizing mental health, quality of life, and unmet medical gender affirmation needs. METHODS: LEGACY is a longitudinal, multisite, clinic-based cohort of adult TGD primary care patients from two federally qualified community health centers in the United States: Fenway Health in Boston, and Callen-Lorde Community Health Center in New York. Eligible adult TGD patients contribute electronic health record data to the LEGACY research data warehouse (RDW). Patients are also offered the option to participate in patient-reported surveys for 1 year of follow-up (baseline, 6-month, and 12-month assessments) with optional HIV and sexually transmitted infection (STI) testing. Biobehavioral data from the RDW, surveys, and biospecimen collection are linked. HIV-related clinical outcomes include pre-exposure prophylaxis uptake (patients without HIV), viral suppression (patients with HIV), and anogenital STI diagnoses (all patients). Medical gender affirmation includes hormones, surgeries, and nonhormonal and nonsurgical interventions (eg, voice therapy). RESULTS: The contract began in April 2018. The cohort design was informed by focus groups with TGD patients (n=28) conducted between August-October 2018 and in collaboration with a community advisory board, scientific advisory board, and site-specific research support coalitions. Prospective cohort enrollment began in February 2019, with enrollment expected to continue through August 2020. As of April 2020, 7821 patients are enrolled in the LEGACY RDW and 1756 have completed a baseline survey. Participants have a median age of 29 years (IQR 11; range 18-82). More than one-third (39.7%) are racial or ethnic minorities (1070/7821, 13.68% Black; 475/7821, 6.07% multiracial; 439/7821, 5.61% Asian or Pacific Islander; 1120/7821, 14.32% other or missing) and 14.73% (1152/7821) are Hispanic or Latinx. By gender identity, participants identify as 33.79% (2643/7821) male, 37.07% (2900/7821) female, 21.74% (1700/7821) nonbinary, and 7.39% (578/7821) are unsure or have missing data. Approximately half (52.0%) of the cohort was assigned female sex at birth, and 5.4% (421/7821) are living with HIV infection. CONCLUSIONS: LEGACY is an unprecedented opportunity to evaluate the impact of medical gender affirmation on HIV-related health. The study uses a comprehensive research methodology linking TGD patient biobehavioral longitudinal data from multiple sources. Patient-centeredness and scientific rigor are assured through the ongoing engagement of TGD communities, clinicians, scientists, and site clinical staff undergirded by epidemiological methodology. Findings will inform evidence-based clinical care for TGD patients, including optimal interventions to improve HIV-related outcomes.

High risk and low uptake of pre-exposure prophylaxis to prevent HIV acquisition in a national online sample of transgender men who have sex with men in the United States.

INTRODUCTION: Trans masculine people who have sex with cisgender ("cis") men ("trans MSM") may be at-risk for HIV infection when they have cis MSM partners or share needles for hormone or recreational drug injection. Limited data are available characterizing indications and uptake of pre-exposure prophylaxis (PrEP) in trans MSM. The aim of this study was to assess PrEP indication and uptake as a means of primary HIV prevention for adult trans MSM in the U.S. METHODS: Between November and December 2017, a national convenience sample of trans MSM in the U.S. (n = 857) was recruited using participatory methodologies and completed an online survey of demographics, HIV risk, PrEP, behavioural and psychosocial factors. Self-reported receptive anal sex or frontal/vaginal sex (with or without a condom) with a cis male sex partner in past six months was an eligibility criterion. A multivariable logistic regression procedure was used to model PrEP indications (yes/no) per an interpretation of U.S. Centers of Disease Control and Prevention recommendations among those without HIV (n = 843). RESULTS: The diverse sample was 4.9% Black; 22.1% Latinx ethnicity; 28.4% non-binary gender identity; 32.6% gay-identified; 82.7% on testosterone. Overall, 84.1% had heard of PrEP. Of these, 33.3% reported lifetime PrEP use (21.8% current and 11.5% past). Based on HIV behavioural risk profiles in the last six months, 55.2% of respondents had indications for PrEP. In a multivariable model, factors associated with PrEP indication included where met sex partners, not having sex exclusively with cismen, higher perceived HIV risk, greater number of partners and high cis male partner stigma (all p < 0.05). DISCUSSION: The majority of trans MSM in this sample had a PrEP indication. Stigma was associated with risk for HIV acquisition and represents a critical target for HIV biobehavioural prevention interventions for trans MSM, who appear to be underutilizing PrEP. CONCLUSIONS: Results from this study support the full inclusion of trans MSM in HIV biobehavioural prevention efforts. Public health interventions and programmes are needed to reach trans MSM that attend to general MSM risk factors as well as to vulnerabilities specific to trans MSM, including the context of stigma from cis male sexual partners.
