Centering the Needs of Transgender, Nonbinary, and Gender-Diverse Populations in Neuroendocrine Models of Gender-Affirming Hormone Therapy.

ABSTRACT: Most studies attempting to address the health care needs of the millions of transgender, nonbinary, and/or gender-diverse (TNG) individuals rely on human subjects, overlooking the benefits of translational research in animal models. Researchers have identified many ways in which gonadal steroid hormones regulate neuronal gene expression, connectivity, activity, and function across the brain to control behavior. However, these discoveries primarily benefit cisgender populations. Research into the effects of exogenous hormones such as estradiol, testosterone, and progesterone has a direct translational benefit for TNG individuals on gender-affirming hormone therapies (GAHTs). Despite this potential, endocrinological health care for TNG individuals remains largely unimproved. Here, we outline important areas of translational research that could address the unique health care needs of TNG individuals on GAHT. We highlight key biomedical questions regarding GAHT that can be investigated using animal models. We discuss how contemporary research fails to address the needs of GAHT users and identify equitable practices for cisgender scientists engaging with this work. We conclude that if necessary and important steps are taken to address these issues, translational research on GAHTs will greatly benefit the health care outcomes of TNG people.

Project description:ImportanceTransgender and nonbinary (TNB) youths are disproportionately burdened by poor mental health outcomes owing to decreased social support and increased stigma and discrimination. Although gender-affirming care is associated with decreased long-term adverse mental health outcomes among these youths, less is known about its association with mental health immediately after initiation of care.ObjectiveTo investigate changes in mental health over the first year of receiving gender-affirming care and whether initiation of puberty blockers (PBs) and gender-affirming hormones (GAHs) was associated with changes in depression, anxiety, and suicidality.Design, setting, and participantsThis prospective observational cohort study was conducted at an urban multidisciplinary gender clinic among TNB adolescents and young adults seeking gender-affirming care from August 2017 to June 2018. Data were analyzed from August 2020 through November 2021.ExposuresTime since enrollment and receipt of PBs or GAHs.Main outcomes and measuresMental health outcomes of interest were assessed via the Patient Health Questionnaire 9-item (PHQ-9) and Generalized Anxiety Disorder 7-item (GAD-7) scales, which were dichotomized into measures of moderate or severe depression and anxiety (ie, scores ≥10), respectively. Any self-report of self-harm or suicidal thoughts over the previous 2 weeks was assessed using PHQ-9 question 9. Generalized estimating equations were used to assess change from baseline in each outcome at 3, 6, and 12 months of follow-up. Bivariate and multivariable logistic models were estimated to examine temporal trends and investigate associations between receipt of PBs or GAHs and each outcome.ResultsAmong 104 youths aged 13 to 20 years (mean [SD] age, 15.8 [1.6] years) who participated in the study, there were 63 transmasculine individuals (60.6%), 27 transfeminine individuals (26.0%), 10 nonbinary or gender fluid individuals (9.6%), and 4 youths who responded "I don't know" or did not respond to the gender identity question (3.8%). At baseline, 59 individuals (56.7%) had moderate to severe depression, 52 individuals (50.0%) had moderate to severe anxiety, and 45 individuals (43.3%) reported self-harm or suicidal thoughts. By the end of the study, 69 youths (66.3%) had received PBs, GAHs, or both interventions, while 35 youths had not received either intervention (33.7%). After adjustment for temporal trends and potential confounders, we observed 60% lower odds of depression (adjusted odds ratio [aOR], 0.40; 95% CI, 0.17-0.95) and 73% lower odds of suicidality (aOR, 0.27; 95% CI, 0.11-0.65) among youths who had initiated PBs or GAHs compared with youths who had not. There was no association between PBs or GAHs and anxiety (aOR, 1.01; 95% CI, 0.41, 2.51).Conclusions and relevanceThis study found that gender-affirming medical interventions were associated with lower odds of depression and suicidality over 12 months. These data add to existing evidence suggesting that gender-affirming care may be associated with improved well-being among TNB youths over a short period, which is important given mental health disparities experienced by this population, particularly the high levels of self-harm and suicide.

Project description:BackgroundTransgender patients often cannot access a provider who is knowledgeable about providing gender-affirming hormone therapy (GAHT). This study evaluated primary care provider (PCP) comfort and experience with, opinions about, and knowledge of prescribing GAHT to adults.MethodsAn anonymous Qualtrics survey was distributed to PCPs in San Diego County. Fisher's exact test assessed any association between age, years in practice, or practice setting and 1) comfort in prescribing GAHT and 2) favorable statements about learning about, providing, and benefitting from training in GAHT. T-tests determined relationship between age, years in practice, or practice type setting with number of correctly answered multiple choice knowledge-based questions out of 4.ResultsOut of 220 responses, median age was 41, 60% had practiced for ≤ 10 years, and 19% had practiced in an academic setting. Forty-two percent did not receive any education about transgender healthcare during medical training. The most commonly reported barrier to providing GAHT was lack of training (74%). PCPs age ≤ 41 (67% vs 49%, p = 0.009), PCPs practicing for ≤ 10 years (65% vs 51%, p = 0.037), and PCPs in non-academic settings (64% vs. 41%, p = 0.013) were more likely to report being comfortable with prescribing GAHT. PCPs age ≤ 41 (89% vs 62%, p < 0.001) and PCPs practicing for ≤ 10 years (86% vs 66%, p < 0.001) were more likely to show interest in learning about GAHT. PCPs age ≤ 41 (74% vs 46%, p < 0.001) and PCPs practicing for ≤ 10 years (70% vs 50%, p = 0.003) were more likely to show interest in prescribing GAHT. Knowledge scores were higher for PCPs age ≥42 (mean 1.7 vs 1.4, p = 0.033) and PCPs working in academic centers (mean 2.0 vs 1.4, p = 0.002).ConclusionYounger (age ≤ 41) and early career (practicing for ≤ 10 years) PCPs reported being more comfortable with prescribing GAHT and had more favorable opinions in learning about, providing, and benefitting from training in GAHT. They are interested in providing GAHT; however, few prescribe GAHT with most reporting lack of training as a major barrier. This was evident with overall low knowledge scores regardless of age, experience, or clinical setting and underscores the need for increased educational efforts in transgender care throughout medical training.

Project description:ImportanceIn the US, transgender, nonbinary, and gender diverse (TGD) adults have high rates of depression. Gender-affirming hormone therapy (GAHT) is associated with improved mental health outcomes, yet existing US studies have short follow ups and lack sample diversity.ObjectiveTo evaluate the use of GAHT delivered in primary care as an intervention for moderate-to-severe depressive symptoms in diverse TGD adult patients.Design, setting, and participantsLEGACY was an observational cohort study conducted in federally qualified community health centers in Boston and New York that followed up TGD patients (N = 3592) from calendar years 2016 to 2019 (48 months). Participants included individuals aged 18 years or older, gender identity different from sex at birth, a past 12-month medical visit, and signed patient consent form in the electronic health record (EHR).ExposuresPrescriptions for GAHT obtained from EHR data, using the date of the first and last GAHT prescription in each calendar year of observation (GAHT within the year vs no GAHT during the year).Main outcomes and measuresA binary outcome of patient-reported moderate-to-severe depressive symptoms was obtained using the validated Patient-Health Questionnaire (PHQ), scoring 10 or greater on the PHQ-9 or scoring 3 or greater on the PHQ-2. Following multiple imputation, generalized estimating equations (GEE) longitudinally modeled GAHT and moderate-to-severe depressive symptoms (n = 20 320 observations) and adjusted for age, gender identity, race and ethnicity, health insurance, federal poverty level, HIV serostatus, number of cohort years, and clinical site.ResultsThe median age of the 3592 patients was 28 (IQR, 24-36) years. Race and ethnicity was diverse (1.3% Asian/Pacific Islander, 11.7% Black, 16.1% Hispanic/Latinx, 63.1% White, 6.8% multiracial, and 1.4% other). In addition, 18.9% were nonbinary, 52.1% lived below the federal poverty level, 34.2% were publicly insured, 4.1% were uninsured, and 5.1% were living with HIV. At baseline, 84.5% of the individuals were prescribed GAHT and 15.3% reported moderate-to-severe depressive symptoms. Patients prescribed GAHT had a statistically significantly lower risk of moderate-to-severe depressive symptoms over follow-up compared with those not prescribed GAHT (adjusted risk ratio, 0.85; 95% CI, 0.75-0.98).Conclusions and relevanceIn this longitudinal observational cohort study, GAHT was associated with lower rates of moderate-to-severe depressive symptoms, highlighting the importance of gender-affirming primary care models for TGD patients.

Project description:ImportanceGender-affirming hormone treatment (GAHT) is a common therapy for transgender individuals to reduce gender dysphoria and improve quality of life. Clarifying the long-term effects of GAHT remains a priority in transgender health research.ObjectiveTo explore whether sex hormones (estradiol and testosterone) are associated with the development of metabolic syndrome in transgender veterans compared with cisgender veterans.Design, setting, and participantsThis retrospective, longitudinal cohort study used International Classification of Diseases, Ninth Revision and International Statistical Classification of Diseases and Related Health Problems, Tenth Revision diagnosis codes for gender dysphoria from the Veterans Health Administration national database to identify transfeminine and transmasculine veterans receiving documented feminizing (estradiol) or masculinizing (testosterone) treatment from January 1, 2006, to December 31, 2019, and for whom the GAHT initiation date and metabolic syndrome component-related data were available. Transgender veterans were matched to cisgender referents.ExposureGender-affirming hormone treatment.Main outcomes and measuresMetabolic syndrome z-scores were calculated based on body mass index, systolic blood pressure, and levels of high-density lipoprotein cholesterol, triglycerides, and blood glucose. Changes in mean z-scores were compared among the transgender and cisgender groups before and after the index date (corresponding to GAHT initiation) using a repeated-measures analysis of variance model.ResultsThe cohort included 1290 participants: 645 transgender (494 [38.3%] transfeminine, 151 [11.7%] transmasculine) and 645 cisgender (280 [21.7%] female, 365 [28.3%] male). Mean (SD) age at the index date was 41.3 (13.2) years. Metabolic syndrome z-scores changed significantly over time and differed significantly across groups. Overall, transmasculine veterans had the greatest percentage increase in mean (SEM) z-scores after vs before the index date (298.0% [57.0%]; P < .001), followed by cisgender females (108.3% [27.5%]; P < .001), cisgender males (49.3% [27.5%]; P = .02), and transfeminine persons (3.0% [10.7%]; P = .77).Conclusions and relevanceIn this cohort study, in both cisgender and transgender veterans, estradiol was associated with reduced metabolic syndrome risk, whereas testosterone was associated with increased risk. However, transmasculine individuals had the greatest risk and transfeminine individuals had the lowest risk of metabolic syndrome associated with these hormones. This is relevant for the management of metabolic syndrome risk factors in cisgender and transgender individuals and to potentially predict the risk of atherosclerotic cardiovascular disease, type 2 diabetes, systolic hypertension, insulin resistance, and nonalcoholic fatty liver disease.
