The Effect of Gender-Affirming Hormones on Gender Dysphoria, Quality of Life, and Psychological Functioning in Transgender Individuals: A Systematic Review

Gender affirming hormone therapy for individuals with gender dysphoria aged <26 years: a systematic review and meta-analysis

OBJECTIVE

In this systematic review and meta-analysis, we assessed and summarised the certainty of the evidence about the effects of gender affirming hormone therapy (GAHT) in individuals with gender dysphoria (GD).

METHODS

We searched Medline, Embase, PsychINFO, Social Sciences Abstracts, LGBTQ+ Source and Sociological Abstracts from inception to September 2023. We included studies comparing GAHT with no GAHT in individuals aged <26 years with GD. Outcomes of interest included psychological and physical effects. Pairs of reviewers independently screened articles, abstracted data and assessed the risk of bias in the included studies. We performed meta-analyses and assessed the certainty of the evidence using the grading of recommendations assessment, development and evaluation (GRADE) approach.

RESULTS

We included 24 studies. Comparative observational studies (n=9) provided mostly very low certainty evidence regarding GD, global function and depression. One comparative observational study reported that the odds of depression may be lower (OR 0.73 (95% CI 0.61 to 0.88), n (number of studies)=1, low certainty) in individuals who received GAHT compared with those who did not. Before-after studies (n=13) provided very low certainty evidence about GD, global function, depression and bone mineral density. Case series studies (n=2) provided high certainty evidence that the proportion of individuals with cardiovascular events 7-109 months after receiving GAHT was 0.04 (95% CI 0.03 to 0.05, n=1, high certainty).

CONCLUSION

There is considerable uncertainty about the effects of GAHT and we cannot exclude the possibility of benefit or harm. Methodologically rigorous prospective studies are needed to produce higher certainty evidence.

Traditional and individual care pathways in gender-affirming healthcare for transgender and gender-diverse individuals - results from the ENIGI follow-up study

Treatment requests in transgender healthcare are heterogenous and not all transgender and gender-diverse individuals want to undergo the various transition-related medical interventions offered. This study aims to explore demographic and treatment-related predictors associated with different transgender care pathways in a multicenter, multinational clinical setting. In this follow-up study, 539 adult participants from Belgium, Germany, and the Netherlands took part and were categorized as following a 'traditional' care pathway (i.e., undergoing all transition-related interventions), an 'individual' care pathway (i.e. any course of treatment deviating from the traditional pathway), or 'no care' pathway (i.e. not seeking transition-related medical interventions.). We analyzed differences in demographic (e.g., gender identity) and clinical variables (e.g., treatment satisfaction), conducting logistic regression analysis and descriptive subgroup analysis. Participants with a non-binary gender were 6.7 times more likely to follow an individual care pathway, while participants with higher treatment satisfaction were less likely to follow an individual care pathway (Odds Ratio: 0.6). We identified four patterns of individual transgender care pathways, some as a function of the sex assigned at birth. The present study provides valuable insights into demographic and treatment-related predictors associated with different transgender care pathways. Healthcare providers should be aware of individual transgender care pathways and the association with (non)-binary genders to provide tailored transgender healthcare and ensure individualized, high-quality service provision.

Changes in affect variability after starting gender-affirming hormone therapy

Negative affect variability is determined by how often and how strongly negative affect changes over time. Cisgender women report greater variability in affect than cisgender men. It has been suggested that sex hormone changes may influence affect variability. Transgender people frequently opt to use sex hormones in the form of gender-affirming hormone therapy (GAHT), but the extent to which GAHT can change negative affect variability is not yet clear. Therefore, this study aims to study changes in negative affect variability after starting GAHT. We have included data from 92 participants from the RESTED study: 47 persons starting masculinizing hormones (MH), i.e. testosterone, and 45 persons starting feminizing hormones (FH), i.e., estrogens and anti-androgens. Participants completed up to 7 consecutive daily diaries at each of three time points: before starting GAHT, and after 3 and 12 months of GAHT. The daily diaries collected participants' reports on symptoms related to negative affect: experienced low mood, less interest, tense feelings and restless feelings. We have used linear mixed models to compare negative affect variability during one week, corrected for mean negative affect, between groups (MH versus FH) and measurement time points. Results show that in the MH group, variability in tense feelings and restless feelings decreased after 3 and 12 months of GAHT, respectively. In the FH group, variability in low mood increased after 3 months and 12 months of GAHT, as did variability in restless feelings after 12 months of GAHT. Group comparisons indicate significant group differences in changes in variability in low mood and restless feelings, with stronger increases in variability of negative affect in the FH group compared to MH group after 3 and 12 months of GAHT. Our findings indicate that variability patterns in negative affect in transgender persons change after starting GAHT, with participants who start masculinizing hormones moving to a profile which more closely resembles that of cisgender men and participants who start feminizing hormones moving to a profile which more closely resembles that of cisgender women. Future studies should focus on measuring both negative and positive affect variability during GAHT, preferably through multiple measurements per day, taking into account diverse social and daily contextual factors during GAHT.

Do hormones and surgery improve the health of adults with gender incongruence? A systematic review of patient reported outcomes

BACKGROUND

Gender diverse people in Australia have higher levels of psychological stress, suicidal ideation and suicide attempts and have poorer self-reported health than cisgender people.

OBJECTIVES

To determine if adults who experience gender incongruence have improved health-related quality of life and mental health with gender affirming treatment (hormone therapy and surgery), compared with no treatment.

DATA SOURCES

PubMed, Web of Science, Embase and Psych Info.

REVIEW METHODS

A systematic review of peer-reviewed publications in English from January 2010 to October 2022. Studies were included where: participants were treated with gender affirming surgery or hormone therapy for minimum 3 months and; validated patient reported outcome measures of health-related quality of life or mental health were reported. Quality of evidence assessment was undertaken using the Let Evidence Guide Every New Decision evaluation tool.

RESULTS

Eighty-one publications were included for analysis. The systematic review indicated that there were significant improvements in the domains of mental illness, gender dysphoria, body image and health-related quality of life following gender affirming medical treatment as measured by a variety of patient reported outcomes. Meta-analysis showed significant improvement in body image (z = 4.47, P < 0.001) and health-related quality of life for psychological (z = 1.99, P = 0.047) and social relationships (z = 3.09, P = 0.002) following gender affirming surgery.

CONCLUSIONS

There is evidence that hormones and surgery as a collective for adults with gender incongruence has therapeutic value and should be considered for funding within Australia's healthcare systems. The development and implementation of patient-reported outcome tools tailored for purpose (GENDER Q) will facilitate future research.

Is cardiovascular disease risk in transgender, gender-diverse, and non-binary adults associated with autonomic imbalance?

Blood pressure is a key indicator of cardiovascular health with chronically high levels increasing the risk of cardiovascular diseases (CVD) such as heart attack and stroke. Emerging evidence shows that transgender, gender-diverse, and non-binary (TGD) adults tend to have higher blood pressure than age-matched cisgender adults, corresponding to an increased CVD risk in this population. Yet, the mechanisms underlying elevated blood pressure in TGD adults remain unclear, posing challenges to TGD-affirming healthcare. Given the autonomic nervous system's role in CVD - wherein reduced parasympathetic and heightened sympathetic activity are key risk factors for CVD - this review explores the question: "Is cardiovascular disease risk in TGD adults associated with autonomic imbalance?" Limited research exists on autonomic balance within TGD populations. Accordingly, this review considers how TGD-specific factors, such as minority stress, lifestyle behaviors, sex and gender, and hormones (i.e., testosterone, estrogen, progesterone), may impact autonomic balance. Finally, this review aims to underscore the critical need for interdisciplinary research to elucidate these mechanisms and advance TGD-inclusive healthcare in the domains of autonomic control of blood pressure and overall cardiovascular health.

Examining gender-specific mental health risks after gender-affirming surgery: a national database study

BACKGROUND

Transgender individuals face heightened psychological distress, including depression, anxiety, and suicidal ideation, partly due to stigma and lack of gender affirmation.

AIM

To evaluate mental health outcomes in transgender individuals with gender dysphoria who have undergone gender-affirming surgery, stratified by gender and time since surgery.

METHODS

This retrospective study utilized the TriNetX database, analyzing U.S. patients aged ≥18 with gender dysphoria (International Classification of Diseases, Tenth Revision [ICD-10] F64) between June 2014 and June 2024. Six cohorts were created based on gender and surgery status: Cohorts A-D included patients with or without surgery, and Cohorts E-F allowed for gender comparison among those with surgery. Propensity score matching controlled for age, race, and ethnicity. Mental health outcomes included depression, anxiety, suicidal ideation, substance use disorder, and body dysmorphic disorder, assessed over two years post-surgery using clinician-verified ICD-10 codes. Body dysmorphic disorder (BDD) was analyzed separately and not conflated with gender dysphoria cohorts to ensure the distinction between these conditions. Statistical analysis employed risk ratios, with P < 0.05 deemed significant.

OUTCOMES

Primary outcomes were differences in mental health disorders, specifically depression, anxiety, suicidal ideation, body-dysmorphic disorder, and substance use disorder, among transgender individuals' post-surgery.

RESULTS

From 107 583 patients, matched cohorts demonstrated that those undergoing surgery were at significantly higher risk for depression, anxiety, suicidal ideation, and substance use disorders than those without surgery. Males with surgery showed a higher prevalence of depression (25.4% vs. 11.5%, RR 2.203, P < 0.0001) and anxiety (12.8% vs. 2.6%, RR 4.882, P < 0.0001). Females exhibited similar trends, with elevated depression (22.9% vs. 14.6%, RR 1.563, P < 0.0001) and anxiety (10.5% vs. 7.1%, RR 1.478, P < 0.0001). Feminizing individuals demonstrated particularly high risk for depression (RR 1.783, P = 0.0298) and substance use disorders (RR 1.284, P < 0.0001).

CLINICAL IMPLICATIONS

Findings suggest the necessity for gender-sensitive mental health support following gender-affirming surgery to address post-surgical psychological risks.

STRENGTHS AND LIMITATIONS

By leveraging ICD-10 codes, we provide a more accurate representation of patient demographics and clinical outcomes, minimizing recall and reporting biases that often limit survey-based research. Limitations include the inability to account for unmeasured confounders such as social support.

CONCLUSION

Gender-affirming surgery, while beneficial in affirming gender identity, is associated with increased risk of mental health issues, underscoring the need for ongoing, gender-sensitive mental health support for transgender individuals' post-surgery.

Early body composition changes in trans women on low-dose estradiol: comparing oral vs sublingual administration using dual energy absorptiometry and bioelectrical impedance analysis

BACKGROUND

Low-dose sublingual estradiol gender-affirming hormone therapy (GAHT) in treatment-naive transgender women effectively suppresses testosterone and initiates breast development, comparable to oral estradiol with cyproterone acetate; however, its impact on body composition remains unstudied.

AIM

To assess early body composition changes with low-dose estradiol, compare sublingual versus oral administration efficacy, and evaluate bioelectrical impedance analysis (BIA) and dual-energy X-ray absorptiometry (DXA) agreement in transgender women undergoing GAHT.

METHODS

In this 6-month prospective study, 22 treatment-naïve transgender women received either 2 mg/day sublingual estradiol (SLE) or combined oral (CO)-2 mg/day oral estradiol plus 10 mg/day cyproterone acetate. Body composition was assessed using DXA and BIA at baseline and after 6 months.

OUTCOMES

Changes in body composition, including lean body mass, fat mass, visceral fat area, waist-to-hip ratio, and android-to-gynoid fat ratio.

RESULTS

BIA and DXA measurements showed good agreement. Both groups experienced decreased lean body mass and increased fat mass. The SLE group showed less increase in total and segmental body fat, and visceral fat area compared to CO. Both treatments decreased waist-to-hip ratio and android-to-gynoid fat ratio, indicating early achievement of a more feminine body shape.

CLINICAL IMPLICATIONS

These findings may help optimize GAHT protocols, improve patient satisfaction with treatment, and enable monitoring outcome assessment in transgender women.

STRENGTHS AND LIMITATIONS

This study provides valuable insights into early body composition changes with low-dose estradiol administration via different administration routes and validates BIA as an alternative to DXA. However, the sample size was relatively small, the study arm allocation was not randomized, and the study duration was only 6 months.

CONCLUSION

Low-dose estradiol induces significant feminizing body composition changes within 6 months of GAHT, with sublingual administration potentially limiting fat accumulation while achieving a feminine body shape.

A review of menopause in transgender and gender diverse individuals

PURPOSE OF REVIEW

This review aims to provide a comprehensive overview of the specific challenges, health considerations, and healthcare needs of transgender and gender diverse (TGD) people navigating menopause, highlighting the intersection of gender identity, hormone treatment, and age-related changes.

RECENT FINDINGS

Research on menopause in TGD individuals is lacking, without guidelines to support clinical management. This is the first review of its type to summarize the described impact of the menopausal transition on TGD individuals, the potential long-term risks associated with both gender-affirming hormone therapy and the intersectionality with aging, and how these risks may impact hormone management and overall comprehensive care.

SUMMARY

By drawing on the shared principles of cisgender menopausal hormone therapy and gender-affirming hormone therapy, providers are well positioned to apply their expertise to support the TGD population during menopause. We recommend using shared decision-making, culturally competent care, and a strong understanding of the biological, personal, and social experiences of TGD people that do not necessarily conform to stereotypically ciswoman experiences.

Experiences of Transformation: The Challenges of Gender Transition for Transgender Women in Pakistan

In a historical development, the Pakistani parliament made significant strides toward recognizing the rights of the third gender by enacting the Transgender Protection of Rights Act in 2018. This legislation represents a pivotal milestone in acknowledging and safeguarding the rights of transgender individuals in Pakistan. The present study sought to investigate the barriers encountered by transgender women in accessing gender-affirmative treatment for the purpose of gender transition. Ten transgender women participated in semi-structured and in-depth interviews, employing the grounded theory method for analysis. Analysis uncovered a spectrum of medical, social, sexual, legal, religious, financial, and psychological barriers that participants faced during the transition process. These findings are contextualized within Pakistan's cultural milieu and examined in relation to existing literature. The outcomes of this research have the potential to enlighten clinicians, academics, policymakers, and other stakeholders about the unique challenges encountered by transgender women, thereby fostering greater awareness and understanding.

Examining body image satisfaction among transfeminine and cisgender female youth in Thailand: a community-based survey

BACKGROUND

Higher levels of body image dissatisfaction play a crucial role in the development and maintenance of eating disorders. Among different age groups, adolescents tend to focus more on their body image. However, there is limited data available on body image satisfaction in transfeminine youth. This study aimed to investigate body image satisfaction among transfeminine youth compared to cisgender female youth and to identify factors associated with body image satisfaction in transfeminine youth. Factors such as exercise and hormone intake were examined for their potential influence on body image satisfaction.

METHODS

We developed a self-administered questionnaire to survey a sample of 600 youth (212 transfeminine and 388 cisgender female), aged 12-25 years, between 2021 and 2022. Body image satisfaction was assessed using the Body Image Concern Inventory Score (BICI), with a higher BICI score indicating greater body image dissatisfaction.

RESULTS

A total of 209 transfeminine youth and 378 cisgender female youth participated in the study. The results showed that transfeminine youth reported higher levels of body image dissatisfaction than cisgender female youth, with mean ± SD scores of 59.3 ± 15.8 and 50.2 ± 15.9, respectively. Notably, regular exercise was associated with greater body image satisfaction (adjusted b = -7.53 [95% CI -14.78 to -0.27]; p-value = 0.04), while gender-affirming hormone intake did not show a significant association with body image satisfaction.

CONCLUSIONS

These findings emphasize the importance of evaluating body image among transfeminine youth and suggest that promoting regular exercise may be an effective strategy to reduce body image dissatisfaction in this population.

Gender-Affirming Hormone Therapy and Depressive Symptoms Among Transgender Adults

Importance

In 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.

Objective

To 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 Participants

LEGACY 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).

Exposures

Prescriptions 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 Measures

A 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.

Results

The 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 Relevance

In 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.

One person, many changes: a socioecological qualitative analysis of the experiences of transfeminine individuals undergoing feminising gender-affirming hormone therapy

Gender-affirming hormone therapy (GAHT) comes with many physical, psychological, and social changes that are often considered in isolation. This research uses a socioecological lens with a sample of 15 Australian transfeminine individuals to investigate the changes experienced during GAHT. Semi-structured interviews were conducted in 2022, with verbatim transcripts analysed using deductive thematic analysis with Bronfenbrenner's Socioecological Model (SEM) as a framework. Analyses revealed two themes intersecting multiple levels of the SEM. Theme 1 contained two sub-themes and broadly encapsulated how interactions with others influenced GAHT experiences. Sub-theme 1 spoke to how stigma creates positive or negative experiences (through the macrosystem, the exosystem, and proximal processes), while sub-theme 2 described how GAHT causes internal changes that promoted stronger interpersonal relationships (person and proximal processes). Theme 2 described how changes occurred over time, with some changes being temporary, and others being delayed (person and time). These themes highlight the interconnected nature of the physical, psychological, and social changes and experiences that can occur during GAHT. Best-practice care for trans people undergoing GAHT needs to be multi-faceted and holistic in order to embed support across different SEM components.

Hormones, Stress, and Heart Disease in Transgender Women with HIV in LITE Plus

INTRODUCTION

Cardiovascular disease (CVD) is a leading cause of death among transgender women and people with HIV. Exogenous estrogen and psychosocial stressors are known risk factors for CVD. Yet, few studies have used biomarkers to examine the role of stress in CVD risk among transgender women with HIV (TWHIV). This analysis examined whether stress moderates relationships between gender-affirming hormone therapy (GAHT) duration and CVD risk among TWHIV.

METHODS

This cross-sectional analysis of baseline data from an observational cohort of 108 Black and Latina TWHIV in Boston, New York, and Washington, DC, enrolled December 2020 to June 2022, measured sociodemographics, medical diagnoses, medications, smoking history, and perceived stress via interviewer-administered surveys. Physiological stress was measured with 14 biomarkers to calculate allostatic load indices (ALI). Forty participants provided saliva samples used to calculate cortisol awakening response and cortisol daily decline. The 2018 American College of Cardiology Revised Pooled Cohort Equation estimated 10-year CVD risk. Data were analyzed in 2024.

RESULTS

GAHT duration was positively associated with CVD risk scores in bivariate regression. In multivariable linear regression models (adjusting for age, income, education), only age and ALI remained significantly associated with CVD risk scores (β 1.13, CI: 1.05, 1.21). No stress measure significantly interacted with GAHT duration to affect CVD risk scores. In visual plots, GAHT duration increased CVD risk scores only for TWHIV experiencing the highest ALI.

CONCLUSIONS

Stress plays an important role in CVD in TWHIV. More research is needed on non-GAHT factors, which influence CVD health among transgender women.

Exploring the role of sex hormones and gender diversity in multiple sclerosis

Sex and sex hormones are thought to influence multiple sclerosis (MS) through effects on inflammation, myelination and neurodegeneration, and exogenous hormones have been explored for their therapeutic potential. However, our understanding of how sex hormones influence MS disease processes and outcomes remains incomplete. Furthermore, our current knowledge is derived primarily from studies that focus exclusively on cisgender populations with exclusion of gender-diverse people. Gender-affirming hormone therapy comprising exogenous sex hormones or sex hormone blocking agents are commonly used by transgender and gender-diverse individuals, and it could influence MS risk and outcomes at various stages of disease. A better understanding of the impact and potential therapeutic effects of both endogenous and exogenous sex hormones in MS is needed to improve care and outcomes for cisgender individuals and, moreover, for gender-diverse populations wherein an evidence base does not exist. In this Perspective, we discuss the effects of endogenous and exogenous sex hormones in MS, including their potential therapeutic benefits, and examine both established sex-based dimorphisms and the potential for gender-diverse dimorphisms. We advocate for future research that includes gender-diverse people to enhance our knowledge of the interplay of sex and sex hormones in MS, leading to the development of more effective and inclusive treatment strategies and improvement of care for all individuals with MS.

Body composition and perceived stress levels in transgender individuals after one year of gender affirming hormone therapy

Introduction

Higher stress levels are linked to increased body fat and decreased bone density, effects that can be exacerbated by lifestyle choices. This is particularly relevant for transgender and gender diverse (TGD) individuals, who often face additional stress from transphobia and social stigma. However, there is limited research on how stress affects body composition and bone health in TGD individuals, particularly in relation to gender-affirming hormone therapy (GAHT). This study examines the impact of perceived stress on these factors in TGD individuals before and after one year of GAHT, compared to a cisgender control group.

Methods

The study assessed 181 individuals, including 74 TGD participants (44 assigned female at birth [AFAB] and 30 assigned male at birth [AMAB]) and 107 controls (56 AFAB and 51 AMAB). Fifty-seven TGD participants completed follow-up one year after starting GAHT. Data collected included clinical history, blood tests, body composition, bone density, and quality of life assessments (Patient Health Questionnaire-9 [PHQ-9] and Perceived Stress Scale [PSS]).

Results

After one year of GAHT, TGD AFAB individuals showed a bone mineral density (BMD) similar to cisgender AMAB individuals, while TGD AMAB individuals' BMD remained significantly lower than cisgender controls. TGD AFAB individuals experienced increases in muscle strength (+8% from baseline), while TGD AMAB individuals showed a 24% increase in fat mass from baseline and an approximate 8% reduction in lean mass. PSS and PHQ scores, initially higher in TGD individuals, did not change significantly after one year of GAHT. A significant correlation was found between body fat percentage and PHQ and PSS scores at baseline and one year after GAHT, respectively.

Discussion

These findings reveal a complex relationship between GAHT, body composition, and perceived stress in TGD individuals, highlighting the need for further research on stress and health outcomes in this population.

Evaluating the Risk of Venous Thromboembolism in Transfeminine and Gender Diverse People: A Retrospective Analysis

OBJECTIVE

The risk of venous thromboembolism (VTE) with feminizing gender-affirming hormone therapy is an area of concern. This analysis aimed to assess whether gender-affirming hormone therapy and other potential risk factors are associated with VTE in transfeminine and gender diverse individuals.

METHODS

We conducted a chart review of 2126 transfeminine and gender diverse adults receiving care within a large urban health system. The primary outcomes were the prevalence of VTE and odds ratios for the association of VTE with insurer, use of estrogen, and select comorbidities.

RESULTS

A history of VTE was documented in 0.8% of the cohort. Those with a history of VTE were older (P < .001), more often self-identified as Hispanic or Black compared to White or Asian (P < .05) and were more likely to have Medicaid or Medicare (P < .01) when compared to those without a history of VTE. The prevalence of hyperlipidemia (P < .001), diabetes mellitus (P < .05), and hypercoagulable conditions (P < .001) were all greater in the positive VTE group. Hyperlipidemia (P < .001), diabetes mellitus (P < .05), and insurer (P < .05) were associated with increased odds of VTE in univariate analyses. None of the exposure variables analyzed were associated with VTE when controlling for age, race, and the number of comorbidities.

CONCLUSIONS

The prevalence of VTE in our cohort was lower than previously observed. VTE was not associated with any one risk factor, including estrogen use, when controlling for age, race, and the number of comorbidities. Those of advanced age and those with multiple cardiometabolic comorbidities may benefit from increased surveillance and mitigation of modifiable risk factors.

Gender Minority Stressors and Psychological Distress Among Chinese Transgender and Gender Diverse People: Variable-Centered, Person-Centered, and Psychological Network Approaches

Mental health disparities in transgender and gender diverse (TGD) populations call for more research examining gender minority stressors (GMS) as antecedents to their psychological distress, especially for the long-underrepresented groups living in conservative societies towards gender minorities. Furthermore, some questions remain underexamined, including the relative, independent influences of various GMS on TGD people's mental well-being (i.e., uniqueness of each stressor); how these stressors would configurate with each other in distinctive patterns to characterize subgroups of TGD people (i.e., beyond-average heterogeneity); and how these stressors would constitute a psychological network and vary in their centrality in that network (i.e., holistic complexity). To narrow such gaps, we examined the links between GMS and TGD people's psychological distress, using survey data collected in 2023 from 410 Chinese TGD people (Meanage = 22.33 years, SD = 4.27; 306 transgender, 70 non-binary/gender-queer/gender-fluid, 26 agender/gender-neutral, 3 intersex, and 5 others). We approached such links from three perspectives. First, variable-centered analyses indicated that while different GMS were considered simultaneously, internalized transphobia, preoccupation with gender dysphoria, and gender-related victimization were uniquely associated with psychological distress. Second, person-centered analyses yielded a 3-profile solution. Psychological distress varied systematically across profiles. Last, network analyses revealed a 3-cluster structure: Distal, Proximal Internal, and TGD-Specific Stressors. Preoccupation with gender dysphoria was the most central node. These findings contribute to a more nuanced understanding of the implications of GMS for TGD people's mental well-being. GMS related to internal struggles with gender identity might be among the central intervention targets to prevent/reduce TGD people's psychological distress.

Menstrual management in transgender and gender diverse individuals: psychiatric and psychosocial considerations

Transgender and gender-diverse (TGD) menstruators are individuals assigned female at birth (AFAB)*, who retain the capacity to menstruate and have a gender identity that differs from their natal sex. Reports indicate up to 1.6 million individuals in the US identify as TGD. Until recently, the mainstream menstrual discourse has failed to capture the experience of transmenstruators. However, a better understanding of the menstrual experiences of TGD-AFAB will allow for more individualized patient-centered care. In this review, we provide the relevant data necessary to inform the psychiatric management of menstruation in TGD-AFAB individuals, including experiences of menstruation, preferences for menstrual management, and the impact on mental health. Our review indicates that menstrual care in TGD patients must be tailored to the individual; clinicians should remain open-minded to the unique experience of transmenstruators; gender-affirming menstrual care is necessary to reduce psychological burden. It should not be assumed that TGD-AFAB menstruators are utilizing appropriate contraceptive methods and should receive contraceptive and fertility preservation counseling. We highlight the importance of having these conversations early in the reproductive arch, even before puberty onset. Keeping in mind the gender minority stress model, in the upcoming sections, we discuss the limited body of literature on mood disorders in TGD-AFAB individuals who menstruate, undergo menstrual suppression, or continue to ovulate. The psychological impact of hormonal therapies is also reviewed.

Impact of Distinct Antiandrogen Exposures on the Plasma Metabolome in Feminizing Gender-affirming Hormone Therapy

CONTEXT

The plasma metabolome is a functional readout of metabolic activity and is associated with phenotypes exhibiting sexual dimorphism, such as cardiovascular disease. Sex hormones are thought to play a key role in driving sexual dimorphism.

OBJECTIVE

Gender-affirming hormone therapy (GAHT) is a cornerstone of transgender care, but longitudinal changes in the plasma metabolome with feminizing GAHT have not been described.

METHODS

Blood samples were collected at baseline and after 3 and 6 months of GAHT from transgender women (n = 53). Participants were randomized to different anti-androgens, cyproterone acetate or spironolactone. Nuclear magnetic resonance-based metabolomics was used to measure 249 metabolic biomarkers in plasma. Additionally, we used metabolic biomarker data from an unrelated cohort of children and their parents (n = 3748) to identify sex- and age-related metabolite patterns.

RESULTS

We identified 43 metabolic biomarkers altered after 6 months in both anti-androgen groups, most belonging to the very low- or low-density lipoprotein subclasses, with all but 1 showing a decrease. We observed a cyproterone acetate-specific decrease in glutamine, glycine, and alanine levels. Notably, of the metabolic biomarkers exhibiting the most abundant "sex- and age-related" pattern (higher in assigned female children and lower in assigned female adults, relative to assigned males), 80% were significantly lowered after GAHT, reflecting a shift toward the adult female profile.

CONCLUSION

Our results suggest an anti-atherogenic signature in the plasma metabolome after the first 6 months of feminizing GAHT, with cyproterone acetate also reducing specific plasma amino acids. This study provides novel insight into the metabolic changes occurring across feminizing GAHT.

The missing clinical guidance: a scoping review of care for autistic transgender and gender-diverse people

The co-occurrence of autism and gender diversity has been increasingly studied in the past decade. It is estimated that ∼11% of transgender and gender-diverse (TGD) individuals are diagnosed with autism. However, there is insufficient knowledge about appropriate gender-related clinical care for autistic TGD individuals. We performed a scoping review of current clinical guidance for the care of TGD individuals to identify what was said about autism. Clinical guidance documents were searched in PubMed, Web of Science, Google Scholar, Embase, Guidelines International Network, and TRIP medical database, as well as reference mining and expert recommendation. Evidence was synthesised by narrative synthesis, recommendation mapping, and reference frequency analysis. Out of the identified 31 clinical guidance documents, only eleven specifically mentioned the intersection between autism and TGD. Key concepts among the available recommendations included advocating for a multidisciplinary approach; emphasising the intersectionality of autism and gender-diverse experiences during assessments; and-importantly-recognising that autism, in itself, does not serve as an exclusion criterion for receiving gender-related care. However, detailed and practical clinical guidance is lacking due to a gap in evidence. Empirical research into the care experiences and outcomes of autistic TGD individuals using a developmental, lifespan, and strengths-based approach is needed to generate evidence-informed and tailored guidance.

This secondary analysis of a randomized clinical trial evaluates the quality of life outcomes of immediate testosterone commencement compared with a 3-month waiting period.

Peri-operative care of transgender and gender-diverse individuals: guidance for clinicians and departments

INTRODUCTION

The objective of this document is to guide best practice to ensure the safety and dignity of transgender and gender-diverse people in the peri-operative period. While transgender and gender-diverse people may have specific health needs in relation to gender dysphoria, their health requirements go beyond their gender identity. Most doctors will provide care to someone who is transgender or gender-diverse at some stage in their career. It is therefore important that all anaesthetists are educated on specific considerations when caring for these patients.

METHODS

A working party was assembled consisting of individuals with experience in direct clinical care of the relevant patient group, those who have expertise in endocrinology and gender-affirming hormones, educators on the topic of transgender and gender-diverse healthcare, and authors of both cisgender and transgender identities. After discussion among the working party, targeted searches of literature were undertaken.

RESULTS

The authors initially came up with a list of over 25 recommendations which was subsequently revised to a list of 15 recommendations after further review by the working party. These included airway assessment and management; management of hormonal therapy; relevant issues in obstetric anaesthesia; and hospital infrastructure and processes.

CONCLUSIONS

This document provides the first guidance produced to advise on best practice to ensure the safety and dignity of trans and gender-diverse individuals in the peri-operative period.

Gender-affirming hormone therapy for transgender and gender-diverse adults in Australia

Gender-affirming hormone therapy (GAHT) is used by many transgender and gender-diverse adults to align physical characteristics with their gender identity, reduce gender incongruence and improve psychological functioning. This narrative review provides an overview of the initiation and monitoring of GAHT in an Australian context. Trans individuals treated with testosterone typically receive standard testosterone doses and formulations recommended for cisgender men, whereas those receiving estradiol GAHT are typically treated with estradiol in combination with an anti-androgen in those without orchidectomy. Proactive monitoring and mitigation of cardiovascular risk factors is pertinent in all transgender and gender-diverse adults and bone health is an important consideration in those using estradiol GAHT.

Priorities for data collection through a prospective cohort study on gender-affirming hormone therapy in Aotearoa New Zealand: community and clinical perspectives

Introduction Gender affirming hormone therapy (GAHT) is an important aspect of health care for many transgender and non-binary (TNB) people, but little is known about the long-term outcomes for TNB people in Aotearoa New Zealand (NZ). Pathways to access GAHT are shifting from secondary care towards primary care, so this is an opportune time to commence local research on long-term health and wellbeing outcomes for people initiating GAHT. Aim This paper aims to report on the key findings from four meetings held to inform the design of a prospective cohort study to follow the journey of people initiating GAHT in primary and secondary care settings in NZ. Methods We worked with a community advisory group of six TNB young people and sought input from 14 health care providers involved in the care of TNB people initiating GAHT (GPs, secondary care doctors, and mental health providers). Semi-structured interview schedules were used to guide discussions. Template analysis was used to initially code data based on themes identified from the interview schedule and new themes from discussions were added. Results Participants shared ideas about recruitment and data collection priorities for baseline and follow-up surveys. These included understanding the journey to starting hormone therapy (information-seeking, decision-making), access to services for GAHT initiation, appropriateness of information provision, receipt of the first prescription, goals for and experience of GAHT, and the unique needs of non-binary people. Discussion Input from a TNB advisory group and health care professionals has informed the development of a survey that will be used to understand the experience of, and outcomes for, people starting GAHT in NZ. Findings from this planned prospective cohort study have the potential to improve access to GAHT for TNB people who wish to pursue this option.

Gender Reassignment and the Role of the Laboratory in Monitoring Gender-Affirming Hormone Therapy

Transgender people experience distress due to gender incongruence (i.e., a discrepancy between their gender identity and sex assigned at birth). Gender-affirming hormone treatment (GAHT) is a part of gender reassignment treatment. The therapeutic goals of the treatment are to develop the physical characteristics of the affirmed gender as far as possible. Guidelines have been developed for GAHT, which recommend dosage as well as different formulations of oestrogen and testosterone for treatment. Questions arise about the metabolic side effects of hormone treatment. Establishing reference ranges for common analytes in transgender individuals remains a task for laboratory medicine. It has been suggested once GAHT is commenced, the reference ranges for affirmed gender are reported for red blood cells, haemoglobin and haematocrit. For transgender assigned-female-at-birth (AFAB) people, testosterone concentrations are recommended to be within the reference interval established for cisgender men and for transgender assigned-male-at-birth (AMAB) people, estradiol concentrations are within the reference range for cisgender women. Sex-specific reference ranges are available for certain laboratory tests, and these may be organ (e.g., heart)-specific. Transgender-specific reference ranges may be a requirement for such tests. Laboratories may need to make decisions on how to report other tests in the transgender population, e.g., eGFR. Interpretation of further tests (e.g., reproductive hormones) can be individualized depending on clinical information. Electronic medical record systems require fields for gender identity/biological sex at birth so that laboratory results can be flagged appropriately. In this review, we aim to summarise the current position of the role of the laboratory in the clinical care of the transgender individual. Prior to the review, we will summarise the genetics of sex determination, the aetiology of gender incongruence, and the recommendations for GAHT and monitoring for the transgender population.

Expectations and Experienced Outcomes Regarding Gender-Affirming Surgeries: A Pilot Study

Purpose

This study aimed to explore in what ways the preoperative expectations of transgender individuals regarding gender-affirming surgery (GAS) align with experienced postoperative outcomes and, subsequently, how these expectations can best be managed to support optimal outcomes.

Methods

In the parent study, interviews were conducted to understand the health care experiences of a group of trans individuals that had or wanted to have gender-affirming surgical care. In this secondary analysis, we focused specifically on the individuals' expectations and experiences about the gender-affirming procedures they desired or underwent. Recruitment occurred from August 2018 to October 2018 at the Amsterdam University Medical Center (VUmc) in the Netherlands. Axial coding and theory-informed thematic analysis were used to assess preoperative expectations and postoperative.

Results

The data regarding expectations related to GAS (ncodes=273) and postoperative experienced outcomes (ncodes=292) yielded a total of four themes-(1) Procedure, recovery, and functional results; (2) Esthetic outcomes of GAS; (3) Improved body image in relation to one's gender role; and (4) Increased psychosocial and sexual wellbeing at large in relation to one's gender role. Each of the four themes were divided into two subthemes: (1) expectations, and (2) experienced outcomes.

Conclusion

Better understanding, education, and support in the decision-making process of trans individuals seeking gender-affirming surgical care is needed to manage expectations and overall outcomes of GAS procedures.

Waiting for transgender care and its effects on health and equality: a mixed-methods population study in the Netherlands

Background

Access to gender-affirming medical care has life-saving effects on transgender and gender diverse (TGD) individuals. An increasing number of TGD individuals seek care which led to waiting times of years. We assessed the duration and effects of excessive waiting for gender-affirming care.

Methods

In this mixed-methods cross-sectional population study, conducted in the Netherlands between June and August 2019, all TGD individuals with experiences with receiving/applying for gender-affirming medical care could participate. Data of participants waiting for care was primarily analyzed. Demographic characteristics and requested care (multiple-choice questions) and the effects of waiting on health were surveyed (open-ended questions). Descriptive statistics were calculated per treatment, and differences in participant characteristics between those waiting for and already in care were assessed through Chi squared tests and post-hoc testing of residuals. Open text answers were thematically analyzed.

Findings

Of all 975 participants, 431 (44.2%) waited for gender-affirming medical care. For 10 out of 20 treatment modalities, the median waiting period was more than a year. Participants already in care were on average higher educated and less-frequently non-binary. Subjective effects of waiting were (very) negative for most treatments. Qualitative findings showed that long waiting was associated with a range of psychosocial distress, poorer health, increasing healthcare consumption, and increased inequality between TGD individuals.

Interpretation

Findings confirm that TGD individuals encounter long waiting times in multiple stages of their gender-affirming medical care. Waiting affects both physical and psychosocial health. Individual resilience and resources can mitigate these experiences, which increase inequality within this already marginalized group.

The effects of gender-affirming hormone therapy and mastectomy on psychopathology, body image, and quality of life in adults with gender dysphoria who were assigned female at birth

PURPOSE

Individuals with gender dysphoria (GD) may request hormone therapy and various surgical operations to change their physical characteristics. The present study aimed to investigate the effects of two treatments, mastectomy and gender-affirming hormone therapy (GAHT), on adults with GD who were assigned female at birth (GD AFAB).

METHODS

In this cross-sectional study, we gathered data from a total of 269 individuals in three groups: (a) untreated group (n = 121), (b) GAHT group (n = 84) who had been receiving treatment for at least 6 months, and (c) GAHT-MAST group (n = 64) who had been using GAHT for at least 6 months and had undergone mastectomy at least 3 months prior. All participants were asked to complete the Symptom Checklist-90-Revised (SCL-90-R), the Body Uneasiness Test (BUT), and the World Health Organization's Quality of Life Questionnaire- Brief Form, Turkish Version (WHOQOL-BREF-Tr).

RESULTS

We found that individuals in the untreated group had higher psychopathological symptoms and body uneasiness scores, and lower quality of life scores compared to both GAHT and GAHT-MAST groups. There was no difference in psychopathology between the GAHT-MAST group and the GAHT group, but body uneasiness scores were lower, and quality of life scores were higher in the GAHT-MAST group.

CONCLUSION

Our study suggests that individuals receiving GAHT improved mental health, body satisfaction, and overall quality of life. Combining mastectomy with GAHT may further enhance these benefits.

Subjective Experiences of Pregnancy, Delivery, and Nursing in Transgender Men and Non-Binary Individuals: A Qualitative Analysis of Gender and Mental Health Concerns

Studies of how gender-diverse individuals experience pregnancy, childbirth, and nursing remain few, mainly focus on the US and contain scarce information about mental health concerns peri-partum. This hinders informed reproductive health decisions and counseling. We used in-depth interviews to examine how gestational gender-diverse individuals in Sweden experience the process of planning and undergoing pregnancy, delivery, and nursing. In total, 12 participants, identifying on the masculine side of the gender spectrum or as non-binary, who had attended Swedish antenatal care and delivered a live birth, were included in the study. Data were analyzed using qualitative thematic content analysis. The analysis resulted in one overarching theme: sustaining gender congruence during pregnancy and three main categories: (1) considering pregnancy; (2) undergoing pregnancy and childbirth; and (3) postnatal reflections. The association between childbearing and being regarded as female permeated narratives. Participants renegotiated the feminine connotations of pregnancy, accessed gender-affirming treatment, and concealed their pregnancy to safeguard their gender congruence. Mis-gendering and breast enlargement triggered gender dysphoria. Social judgment, loneliness, information shortages, hormonal influence and cessation of testosterone increased gender dysphoria and strained their mental health. Depression exacerbated gender dysphoria and made it harder to claim one's gender identity. Dissociation was used to handle a feminized body, vaginal delivery, and nursing. Pregnancy was easier to envision and handle after masculinizing gender-affirming treatments. The results deepen the understanding of gender dysphoria and may be used to inform reproductive counseling and healthcare development. Research outcomes on mental health concerns provide a basis for further research.

The influence of the severity of gender dysphoria on anxiety, depression, suicidal ideation, and non-suicidal self-injury in Chinese transgender, nonbinary, and gender-diverse youth

Background: Gender dysphoria (GD) is frequently reported among transgender, nonbinary, and gender-diverse (TNG) populations, and is closely related to anxiety, depression, suicidal ideation, and non-suicidal self-injury (NSSI). This study aimed to understand how GD influences the four mental health disparities among TNG youth, and to compare these outcomes depending on the severity of GD. Methods: 96,218 College students participated in the survey, of which the analysis was run on an extracted sub-set data of 2,315 (2.40%) TNG youth, with a mean age of 19.46 (SD = 1.52). Self-reported inventories measured sociodemographic factors, the severity of GD (Utrecht Gender Dysphoria Scale-Gender Spectrum), anxiety (seven-item Generalized Anxiety Disorder Questionnaire), depression (nine-item Patient Health Questionnaire), suicidal ideation (Suicidal Behaviors Questionnaire-Revised), and NSSI (Clinician-Rated Severity of Non-Suicidal Self-Injury Scale). Binary logistic regression assessed the association between significant GD and the four psychiatric disorders. Adjusted multiple logistic regression, and directed acyclic graph (DAG) analyses were conducted to explore the activating relationship among GD, sociodemographic factors, and psychiatric disorders. Results: 1,582 (68.30%) TNG youth who experienced significant levels of GD (total scores cutoff >= 46) were entered into the analyses. Binary logistic regression displayed significantly positive associations between significant GD and anxiety, depression, suicidal ideation, and NSSI. Multiple regression models showed risk factors included poor relationship with one's father/mother, tobacco smoking, alcohol consumption, and having a lower subjective social status. While family harmony, a higher father's educational level, and partaking in exercise were protective factors that exerted distinct impacts on these four psychiatric disorders. DAG findings showed a poor relationship with one's father with significant GD via other socio-demographic characteristics, activated psychiatric disorders. Conclusions: TNG youth with higher levels of GD also exhibited more severe anxiety, depression, suicidal ideation, and NSSI. Tailored interventions should be provided to prioritize relieving those with severe GD to protect TNG youth from psychiatric outcomes further.

Dermatological considerations for transgender and gender diverse patients: An Australian perspective

Transgender and gender diverse (TGD) individuals are a group that experiences significant health disparities. In the multidisciplinary management of TGD patients, dermatologists may participate in managing skin- and hair-related issues which contribute to gender affirmation and to the cutaneous sequelae of gender-affirming hormone therapy. This review aims to highlight the unique needs of TGD patients, particularly from the perspective of Australian dermatologists. We review appropriate terminology critical for TGD care, gender affirmation in the Australian healthcare landscape, dermatological considerations for TGD patients and considerations for management.

Structural stigma, gender-affirming interventions, and identity concealment as determinants of depression and life satisfaction among trans adults in 28 European countries

Background

Although medical gender-affirming interventions (GAIs) are vital for most transgender individuals, previous evidence regarding their impacts on psychological well-being is mixed. While some studies reported improvements, others failed to find such effects. Using a large-scale dataset of trans adults from 28 European countries, we aimed to understand how structural stigma and identity concealment might explain this inconsistency.

Method

15,845 trans adults who participated in the EU-LGBTI-II survey, including measures of gender-affirming interventions, identity concealment, and life satisfaction and depression, were included in the analyses. Structural stigma was measured as the discriminatory laws, social policies, and public attitudes. The data was analyzed with multilevel moderated mediation analyses.

Results

Results demonstrated that structural stigma was associated with lower levels of undergoing GAIs. Also, GAIs were indirectly associated with higher levels of life satisfaction and lower levels of depression through increased identity concealment. Structural stigma moderated this association such that these indirect effects were amplified for trans adults living in countries with lower structural stigma.

Conclusions

Results suggest that identity concealment might protect the mental health of trans adults undergoing GAIs, especially in low-stigma contexts, via increased identity concealment. Thus, policies and interventions targeting discriminatory legislation and negative societal attitudes should be implemented to promote access to GAIs and to improve the well-being of transgender individuals, and trans individuals should be supported in their identity management processes.

The Impact of Gender-Affirming Hormone Therapy on Physical Performance

CONTEXT

The inclusion of transgender people in elite sport has been a topic of debate. This narrative review examines the impact of gender-affirming hormone therapy (GAHT) on physical performance, muscle strength, and markers of endurance.

EVIDENCE ACQUISITION

MEDLINE and Embase were searched using terms to define the population (transgender), intervention (GAHT), and physical performance outcomes.

EVIDENCE SYNTHESIS

Existing literature comprises cross-sectional or small uncontrolled longitudinal studies of short duration. In nonathletic trans men starting testosterone therapy, within 1 year, muscle mass and strength increased and, by 3 years, physical performance (push-ups, sit-ups, run time) improved to the level of cisgender men. In nonathletic trans women, feminizing hormone therapy increased fat mass by approximately 30% and decreased muscle mass by approximately 5% after 12 months, and steadily declined beyond 3 years. While absolute lean mass remains higher in trans women, relative percentage lean mass and fat mass (and muscle strength corrected for lean mass), hemoglobin, and VO2 peak corrected for weight was no different to cisgender women. After 2 years of GAHT, no advantage was observed for physical performance measured by running time or in trans women. By 4 years, there was no advantage in sit-ups. While push-up performance declined in trans women, a statistical advantage remained relative to cisgender women.

CONCLUSION

Limited evidence suggests that physical performance of nonathletic trans people who have undergone GAHT for at least 2 years approaches that of cisgender controls. Further controlled longitudinal research is needed in trans athletes and nonathletes.

Quality of life and associated factors in Swiss trans people: a cross-sectional study

Background

Experiences of stressful life events during transition may have a negative impact on quality of life (QoL) in trans persons. Little attention has been paid to this population in Switzerland, resulting in sparse data on their QoL and associated social factors.

Methods

30 participants were recruited during their medical transition treatment and surveyed on their experiences within this time period (13 months after the first medical intervention on average). After performing a diagnostic interview to evaluate their mental health, health-related QoL, psychological distress, self-esteem and the impact of life events that occurred in the last six months on participants were further assessed.

Results

Approximately 17% of participants had suffered from major depression, 43% reported having had suicidal thoughts or having attempted suicide, and 43% suffered from an anxiety disorder. Psychological distress was twice as high compared to the norm values of the cis population. With regard to QoL, trans individuals showed impairments in the mental domain. Stressful life events were particularly evident on a psychological and social level. Analysis showed a negative correlation between impact of life events and mental QoL and between psychological distress and mental QoL. At the same time, there was a positive correlation between self-esteem and mental QoL. Psychological distress and self-esteem emerged as independent significant predictors of mental QoL.

Conclusion

This study shows lowered mental QoL and associations of low mental QoL with psychological distress, low self-esteem and stressful life events in trans individuals in Switzerland. The findings concur with the Gender Minority Stress Model and point out that medical transition must not be viewed in isolation but must be embedded in the framework of integrative psychosocial support.

Physical activity behaviors in trans and gender diverse adults: a scoping review

Background : There is currently limited data regarding the physical activity behaviors of trans and gender diverse people (including binary and non-binary identities; henceforth trans). The aim of this review was to synthesize the existing literature in this area, with a focus on physical activity behaviors as they relate to health (e.g. health benefits, risks of adverse health outcomes). Methods : A scoping review protocol was used to search Medline, Scopus, ProQuest, and CINAHL in order to identify qualitative and quantitative articles, published as of September 2023, that reported physical activity behaviors in trans adults. Quality assessments were conducted based on standard criteria. Results : Twenty-four articles were included in the final analysis, with methodological quality ranging from 0.45 to 0.95 on a scale ranging from 0.0 (low quality) to 1.0 (high quality). Five articles reported low levels of physical activity compared to global health recommendations and one article reported physical activity exceeding the minimum recommendation. Nine articles reported lower levels of physical activity in trans people compared to cisgender people, whereas two reported similar levels of physical activity and one reported higher levels in trans people. A total of 12 different measures were used to assess physical activity levels, of which only seven were validated measures. Seven articles reported compulsive exercise in trans people and five articles reported physical health risks in a sample of trans people with low physical activity levels. Five articles reported physical activity levels influenced by gender congruence or body satisfaction. Six articles reported physical activity influenced by minority stress, experienced discrimination, or anticipated discrimination. Discussion : This review highlights the need for further research regarding the physical activity behaviors of trans individuals, especially with regard to the impact on health (e.g. excessive, or insufficient levels of activity) and consideration of consistency of physical activity measures and reporting. The findings suggest a need to consider the unique influences on physical activity participation in this population when providing services and/or promoting physical activity in support of health.

The Utility of Preclinical Models in Understanding the Bone Health of Transgender Individuals Undergoing Gender-Affirming Hormone Therapy

PURPOSE OF REVIEW

To summarise the evidence regarding the effects of gender-affirming hormone therapy (GAHT) on bone health in transgender people, to identify key knowledge gaps and how these gaps can be addressed using preclinical rodent models.

RECENT FINDINGS

Sex hormones play a critical role in bone physiology, yet there is a paucity of research regarding the effects of GAHT on bone microstructure and fracture risk in transgender individuals. The controlled clinical studies required to yield fracture data are unethical to conduct making clinically translatable preclinical research of the utmost importance. Novel genetic and surgical preclinical models have yielded significant mechanistic insight into the roles of sex steroids on skeletal integrity. Preclinical models of GAHT have the potential inform clinical approaches to preserve skeletal integrity and prevent fractures in transgender people undergoing GAHT. This review highlights the key considerations required to ensure the information gained from preclinical models of GAHT are informative.

Decoding the Misinformation-Legislation Pipeline: an analysis of Florida Medicaid and the current state of transgender healthcare

Background

The state of evidence-based transgender healthcare in the United States has been put at risk by the spread of misinformation harmful to transgender people. Health science librarians can alleviate the spread of misinformation by identifying and analyzing its flow through systems that affect access to healthcare.

Discussion

The author developed the theory of the Misinformation - Legislation Pipeline by studying the flow of anti-transgender misinformation from online echo chambers through a peer-reviewed article and into policy enacted to ban medical treatments for transgender people in the state of Florida. The analysis is precluded with a literature review of currently accepted best practices in transgender healthcare, after which, the author analyzes the key report leveraged by Florida's Department of Health in its ban. A critical analysis of the report is followed by a secondary analysis of the key peer-reviewed article upon which the Florida Medicaid authors relied to make the decision. The paper culminates with a summation of the trajectory of anti-transgender misinformation.

Conclusion

Misinformation plays a key role in producing legislation harmful to transgender people. Health science librarians have a role to play in identifying misinformation as it flows through the Misinformation - Legislation Pipeline and enacting key practices to identify, analyze, and oppose the spread of harmful misinformation.

Sex hormones, insomnia, and sleep quality: Subjective sleep in the first year of hormone use in transgender persons

STUDY OBJECTIVES

Transgender persons can use gender-affirming hormone therapy (GAHT) to align their physical appearance with their identified gender. Many transgender persons report poor sleep, but the effects of GAHT on sleep are unknown. This study examined the effects of a 12 months of GAHT use on self-reported sleep quality and insomnia severity.

METHODS

A sample of 262 transgender men (assigned female at birth, started masculinizing hormone use) and 183 transgender women (assigned male at birth, started feminizing hormone use), completed self-report questionnaires on insomnia (range 0-28), sleep quality (range 0-21) and sleep onset latency, total sleep time and sleep efficiency before start of GAHT and after 3, 6, 9, and 12 months of GAHT.

RESULTS

Reported sleep quality showed no clinically significant changes after GAHT. Insomnia showed significant but small decreases after 3 and 9 months of GAHT in trans men (-1.11; 95%CI: -1.82; -0.40 and -0.97; 95%CI: -1.81; -0.13, respectively) but no changes in trans women. In trans men, reported sleep efficiency decreased by 2.8% (95%CI: -5.5%; -0.2%) after 12 months of GAHT. In trans women, reported sleep onset latency decreased by 9 min (95%CI: -15; -3) after 12 months of GAHT.

CONCLUSIONS

These findings show that 12 months of GAHT use did not result in clinically significant changes in insomnia or sleep quality. Reported sleep onset latency and reported sleep efficiency showed small to modest changes after 12 months of GAHT. Further studies should focus on underlying mechanisms by which GAHT could affect sleep quality.

Transgender health and the impact of aging and menopause

Gender affirming hormone therapy (GAHT) is used by many transgender people to reduce gender incongruence and improve psychological functioning. As GAHT shares many similarities with menopausal hormone therapy, clinicians supporting people through menopause are ideally placed to manage GAHT. This narrative review provides an overview of transgender health and discusses long-term effects of GAHT to consider when managing transgender individuals across the lifespan. Menopause is less relevant for transgender individuals who take GAHT (often given lifelong) to achieve sex steroid concentrations generally in the range of the affirmed gender. For people using feminizing hormone therapy, there is an elevated risk of venous thromboembolism, myocardial infarction, stroke and osteoporosis relative to cisgender individuals. For trans people using masculinizing hormone therapy, there is an increased risk of polycythemia, probable higher risk of myocardial infarction and pelvic pain which is poorly understood. Proactive mitigation of cardiovascular risk factors is important for all transgender people and optimization of bone health is important for those using feminizing hormones. With a lack of research to guide GAHT in older age, a shared decision-making approach is recommended for the provision of GAHT to achieve individual goals whilst minimizing potential adverse effects.

The significance of structural stigma towards transgender people in health care encounters across Europe: Health care access, gender identity disclosure, and discrimination in health care as a function of national legislation and public attitudes

BACKGROUND

According to the minority stress theory, stigma affects the health of marginalized populations. Previous stigma research has focused on the health effects of individual and interpersonal stigma, paying less attention to structural factors. Laws on legal gender recognition affect the lives of transgender individuals in unique ways. The fact that these laws and population attitudes vary greatly between European countries, offer a unique opportunity to study the role of structural stigma in the lives of transgender individuals. Little is known about how transgender specific structural stigma relates to individual health determinants. Consequently, the aim of this study was to explore the association between structural stigma and access to gender affirming care, gender identity disclosure in health care, and experiences of discrimination in health care across 28 European countries.

METHODS

By using multilevel regression, we combined data on health seeking behavior, transgender identity disclosure to health care providers, and experiences of discrimination in health care from 6,771 transgender individuals participating in the 2012 European Union Lesbian, Gay, Bisexual and Transgender survey with a structural stigma measure, consisting of population attitudes towards transgender individuals as well as national legislation on gender recognition. Reasons to refrain from seeking care and discrimination in health care were assessed by categorizing countries as low or high in structural stigma and using Chi-square statistics.

RESULTS

Country-level structural stigma was negatively associated experiences of seeking gender affirming care and positively associated with concealment of being transgender to health care providers. Identity concealment was associated with a lower likelihood of exposure to discrimination in the health care setting across countries regardless of their level of structural stigma. The most prevalent reasons to forgo gender affirming care were shared between low and high structural stigma country groups and centered around fear.

CONCLUSION

The results highlight the importance of changing stigmatizing legislation and population attitudes to promote access to gender affirming care as well as openness of being transgender towards providers. Measures to decrease discrimination in the health care setting are warranted in high as well as in low structural stigma countries.

Pelvic pain in transmasculine adolescents receiving testosterone therapy

Background: Pelvic pain is a common complaint among individuals assigned female at birth. However, few studies have explored pelvic pain among transmasculine patients on gender-affirming testosterone treatment, and most of these were performed in adult populations. Aims: The aim of our study was to investigate the prevalence, risk factors, nature and treatment of pelvic pain among trans adolescents on testosterone. Methods: A retrospective cohort study was performed on all trans adolescents started on gender-affirming testosterone treatment at our institution between 2007 and 2020. Results: Among 158 trans adolescents who were started on testosterone therapy and followed-up for at least six months, 37 (23.4%) reported pelvic pain, with a median interval between testosterone initiation and reported onset of pain of 1.6 months (range 0.3-6.4). The prevalence of pelvic pain was higher in patients who were receiving menstrual suppression (n = 36, 26.3%) compared to those who were not (n = 1, 4.8%), giving a risk difference of 21.5% (95% CI 9.8% to 33.2%, p = 0.028). The most common descriptive terms were "cramps" (n = 17, 45.9%) and "similar to previous period pain" (n = 8, 21.6%). A range of different pharmacological strategies were employed, including paracetamol, NSAIDs, danazol, norethisterone, medroxyprogesterone, etonogestrel implant, intra-uterine device, goserelin and pelvic floor physiotherapy, with variable outcomes. Conclusion: In conclusion, we report here - in what is to our knowledge the first time - the prevalence rate of pelvic pain in trans adolescents on gender-affirming testosterone treatment, and observe that a quarter of them described pelvic pain. Limitations of our study include its retrospective nature, which is likely to be associated with under-reporting of pelvic pain, and the limited documentation of the nature and likely causes of this pain within the medical records. Prospective longitudinal studies to better understand the nature, etiology and optimal management of testosterone-associated pelvic pain are therefore warranted.

Regulation of drug-metabolizing enzymes by sex-related hormones: clinical implications for transgender medicine

Transgender medicine is a diverse and growing clinical field with unmet gaps in pharmacological knowledge. Hormone therapy (testosterone or estrogen treatment), one part of the standard of medical care for transgender adults, aligns secondary sex characteristics with an individual's gender identity and expression. Despite established effects of sex steroids on drug-metabolizing enzyme expression and activity in vitro and in animal models, the effect of long-term, supraphysiological sex hormone treatment on drug metabolism in transgender adults is not yet established. Here, we synthesize available in vitro and animal model data with pharmacological concepts in transgender medicine to predict potential effects of sex steroids on drug-metabolizing enzymes, and their relationship with potential hormone-drug interactions, in transgender medicine.

Testosterone concentrations and prescription patterns of 1% testosterone gel in transgender and gender diverse individuals

Background

Masculinising hormone therapy with testosterone is used to align an individual's physical characteristics with their gender identity. Standard testosterone doses and formulations recommended for hypogonadal cisgender men are typically administered, although there are currently limited data evaluating the use of 1% testosterone gel in gender-affirming hormone therapy regimens.

Objectives

The objective of the study was to assess the prescription patterns and serum total testosterone concentrations achieved with 1% testosterone gel in trans and gender diverse individuals.

Materials and Methods

A retrospective cross-sectional analysis was undertaken of trans individuals at a primary and secondary care clinic in Melbourne, Australia. Sixty-seven individuals treated with 1% testosterone gel were included. Primary outcomes were testosterone dose and serum total testosterone concentration achieved.

Results

Median age was 25 (22-30) years and median duration of testosterone therapy was 12 (7-40) months. Thirty-five (52%) individuals had a nonbinary gender identity. Initial median testosterone dose was 25 mg (12.5-31.3) daily. Fifty-two (78%) individuals commenced doses <50 mg daily, the recommended starting dose for hypogonadal cisgender men. Median total testosterone concentration achieved was 11.9 nmol/l (7.3-18.6). Polycythaemia (haematocrit >0.5) was documented in eight of 138 (6%) laboratory results in six individuals.

Discussion and Conclusions

One percent testosterone gel achieves serum total testosterone concentrations in the cisgender male reference range. A high proportion of individuals had a nonbinary gender identity and most individuals commenced a lower dose than that typically administered to hypogonadal cisgender men, potentially related to slow or 'partial' masculinisation goals.

Short-Term Effects of Gender-Affirming Hormone Therapy on Dysphoria and Quality of Life in Transgender Individuals: A Prospective Controlled Study

Background

Gender affirming hormone therapy (GAHT), whilst considered the standard of care in clinical guidelines for the treatment of many transgender (trans) people is supported by low quality evidence. In this prospective longitudinal controlled study, we aimed to examine the effect of newly commencing GAHT on gender dysphoria and quality of life (QoL) over a 6 month period.

Methods

Adult trans (including those with binary and/or non-binary identities) people newly commencing standard full-doses of masculinising (n = 42; 35 = trans masculine, 7 = non-binary) or feminising (n = 35; 33 = trans feminine, 2 = non-binary) GAHT and cisgender participants (n=53 male, n=50 female) were recruited to participate in this longitudinal prospective study. This analysis of gender dysphoria measured by the Gender Preoccupation and Stability Questionnaire and QoL measured by the RAND Short-Form 36 Health survey at baseline, 3 and 6 months after commencement of GAHT was a prespecified secondary outcome. Dysphoria and QoL over time in those starting GAHT compared to cisgender comparison group matched for their presumed sex at birth is reported as the mean difference (95% confidence interval) adjusted for age.

Results

In trans people initiating masculinising GAHT, there was a decrease in gender dysphoria with adjusted mean difference -6.80 (-8.68, -4.91), p < 0.001, and a clinically significant improvement in emotional well-being [adjusted mean difference 7.48 (1.32, 13.64), p = 0.018] and social functioning [adjusted mean difference 12.50 (2.84, 22.15), p = 0.011] aspects of QoL over the first 6 months of treatment relative to the cisgender female comparison group. No significant differences were observed in other QoL domains. In trans people initiating feminising GAHT, there was a decrease in gender dysphoria [adjusted mean difference -4.22 (-6.21, -2.24), p < 0.001] but no differences in any aspects of QoL were observed.

Conclusions

In the short-term, our findings support the benefit of initiating masculinising or feminising GAHT for gender dysphoria. Masculinising GAHT improves emotional well-being and social functioning within 6 months of treatment. Multidisciplinary input with speech pathology and surgery to support trans people seeking feminisation is likely needed. Further longitudinal studies controlled for other confounders (such as the presence of social supports) contributing to QoL are needed.
