Transgender healthcare: metabolic outcomes and cardiovascular risk

Transgender identity is often associated with gender dysphoria and minority stress. Gender-affirming hormone treatment (GAHT) includes masculinising or feminising treatment and is expected to be lifelong in most cases. Sex and sex hormones have a differential effect on metabolism and CVD in cisgender people, and sex hormone replacement in hypogonadism is associated with higher vascular risk, especially in ageing individuals. Using narrative review methods, we present evidence regarding metabolic and cardiovascular outcomes during GAHT and propose recommendations for follow-up and monitoring of metabolic and cardiovascular risk markers during GAHT. Available data show no increased risk for type 2 diabetes in transgender cohorts, but masculinising GAHT increases lean body mass and feminising GAHT is associated with higher fat mass and insulin resistance. The risk of CVD is increased in transgender cohorts, especially during feminising GAHT. Masculinising GAHT is associated with a more adverse lipid profile, higher haematocrit and increased BP, while feminising GAHT is associated with pro-coagulant changes and lower HDL-cholesterol. Assigned male sex at birth, higher age at initiation of GAHT and use of cyproterone acetate are separate risk factors for adverse CVD markers. Metabolic and CVD outcomes may improve during gender-affirming care due to a reduction in minority stress, improved lifestyle and closer surveillance leading to optimised preventive medication (e.g. statins). GAHT should be individualised according to individual risk factors (i.e. drug, dose and form of administration); furthermore, doctors need to discuss lifestyle and preventive medications in order to modify metabolic and CVD risk during GAHT. Follow-up programmes must address the usual cardiovascular risk markers but should consider that biological age and sex may influence individual risk profiling including mental health, lifestyle and novel cardiovascular risk markers during GAHT.

Metabolic and cardiovascular risks of hormone treatment for transgender individuals

Identifying metabolic and cardiovascular risks of gender-affirming hormone therapy (GAHT) is challenging due to other confounding variables that affect patient outcomes and the diversity of treatment regimes. Masculinising hormone therapy produces atherogenic lipid profiles, while effects on other metabolic parameters are not consistent. There is insufficient evidence to conclude if cardiovascular disease risk among transmen is increased. The effects of feminising hormone therapy on metabolic parameters do not demonstrate a consistent pattern in the available literature. However, the risk of venous thromboembolism is greater in transwomen than in cis-gender men and women with a possible increase in cardiovascular disease risk. It is recommended to discuss the potential effects of GAHT on cardiovascular health and encourage patients seeking GAHT to adopt a healthy lifestyle. Performing baseline and periodic assessments of cardiovascular risk factors would enable early identification and interventions. In high-risk individuals, the cardiovascular effects of hormonal regimes might impact the treatment decision.

Physical Activity, Anxiety, Depression, and Body Image in Trans Individuals: An Exploratory Study

Physical activity (PA), mental health, and body image are some important health topics in the transgender population that have been recently discussed and appear to play a crucial role in the quality of life of the trans population. This study aims to elucidate the complex interplay of these variables and their implications for the well-being of trans individuals.

METHODS

In a cross-sectional study, 75 Portuguese transgender individuals (M = 23.68; SD ± 6.59) were recruited to participate in this study. The participants completed three questionnaires related to the assessment of physical activity (IPAQ), depressive and anxious symptomatology (HADS), and satisfaction with body image (BISQp).

RESULTS

Trans individuals showed a total energy expenditure of 3316.40 metabolic equivalent tasks (METS), had a moderate level of anxiety symptomatology, and low levels of satisfaction with body image. Satisfaction with body image was negatively associated with anxiety (r = -0.441, p < 0.01) and depression symptomatology (r = -0.600, p < 0.01).

CONCLUSIONS

The implementation of inclusive programs that promote body acceptance and coping strategies, particularly within the context of physical exercise, may help alleviate distress related to body image dissatisfaction while also addressing underlying anxiety and depression symptoms.

Physical activity among transgender individuals: A systematic review of quantitative and qualitative studies

Transgender individuals face stigma, discrimination, and other barriers impacting their ability to engage in physical activity (PA). We aim to review current literature on PA among transgender individuals. A systemic literature search of research studies from 2010-2023 was conducted. Studies must have reported a measure of PA and gender, be original research, and focus on transgender participants' PA. Rates of PA for transgender individuals were lower compared to cisgender or sexual minority individuals. Transgender women were less likely to engage in PA than other groups. Qualitative results suggest transgender oppression, stigma, discrimination, body image, unwelcoming environments (gyms, locker rooms, swimming pools), and the dichotomous structure of sport contribute to lower rates of PA among transgendered individuals. Disparities in PA for transgender individuals exist. Policy, environment, and system changes are needed to reduce transgender stigma in sport and PA settings. Current legislation is being developed and implemented in the United States regarding the place of transgender individuals in sport and PA. These results should inform public discourse on the topic.

Sex Steroids Regulate Liver Fat Content and Body Fat Distribution in Both Men and Women: A Study in Transgender Persons

CONTEXT

Liver fat content and visceral fat volume are associated with insulin resistance and cardiovascular disease and are higher in men than in women.

OBJECTIVE

To determine the effect of estradiol and testosterone treatment on liver fat and visceral fat in transgender persons.

DESIGN

Open-label intervention study (SHAMVA) with a 1-year follow-up.

SETTING

Gender clinic in a hospital.

PATIENTS

8 trans women and 18 trans men receiving hormone treatment.

INTERVENTIONS

Trans women received an antiandrogen and after 6 weeks estradiol was added. Trans men were randomized to receive triptorelin, testosterone, and anastrozole for 12 weeks or triptorelin and testosterone for 12 weeks, followed by only testosterone until week 52.

MAIN OUTCOME MEASURES

Liver fat content, visceral and abdominal subcutaneous fat volume, measured by magnetic resonance spectrometry or imaging at baseline, 6, 8, 18, and 58 weeks in transwomen or at baseline; at 6 and 12 weeks in trans men with anastrozole; and at 52 weeks in trans men without anastrozole.

RESULTS

In trans women, liver fat content decreased by 1.55% (-2.99 to -0.12) after 58 weeks, compared to week 6. Visceral fat did not change. In trans men with anastrozole, the liver fat content and visceral fat volume did not change. In trans men without anastrozole, after 52 weeks, liver fat content increased by 0.83% (0.14 to 1.52) and visceral fat volume increased by 34% (16 to 51).

CONCLUSIONS

Sex hormones regulate liver fat content and visceral fat in men and women.

Sports Participation and Transgender Youths

This Viewpoint describes recent legislation and recommendations from statewide athletic associations regarding sports participation for transgender children and adolescents.

Low Pretreatment Bone Mineral Density in Gender Diverse Youth

Gender diverse adolescents have low pretreatment bone mineral density (BMD), with variable changes in BMD after initiation of gender-affirming treatment. We aimed to assess factors associated with low BMD in gender diverse youth. Sixty-four patients were included in our analysis (73% assigned male at birth). Subtotal whole-body BMD Z-scores were low in 30% of patients, and total lumbar spine BMD Z-scores low in 14%. There was a positive association with body mass index, and no association with vitamin D level. Male sex assigned at birth was associated with lower pretreatment BMD, with lower average BMD Z-scores compared to previous studies.

Insights Into the Cardiomodulatory Effects of Sex Hormones: Implications in Transgender Care

Transgender individuals that undergo gender-affirming hormone therapy may experience discrimination in the health care setting with a lack of access to medical personnel competent in transgender medicine. Recent evidence suggests that gender-affirming hormone therapy is associated with an increased risk of cardiovascular diseases and cardiovascular risk factors. A recent statement from the American Heart Association reinforces the importance of cardiovascular-focused clinical management and the necessity for more research into the impact of gender-affirming hormone therapy. With this in mind, this review will highlight the known cardiovascular risk factors associated with gender-affirming hormone therapy and identify potential molecular mechanisms determined from the limited animal studies that explore the role of cross-sex steroids on cardiovascular risk. The lack of data in this understudied population requires future clinical and basic research studies to inform and educate clinicians and their transgender patient population to promote precision medicine for their care to improve their quality of life.

Sex Differences in Athletic Performance: Perspectives on Transgender Athletes

Sex hormone concentrations, particularly testosterone, are primary determinants of sex-based differences in athletic and sports performance, and this relationship may inform fair competition and participation for athletes. This article describes the sex-based dichotomy in testosterone and the implications for sex-based differences in individual sports performance, including factors that relate to athletic performance for transgender individuals, and areas of future investigation.

Endocrine Health and Health Care Disparities in the Pediatric and Sexual and Gender Minority Populations: An Endocrine Society Scientific Statement

Endocrine care of pediatric and adult patients continues to be plagued by health and health care disparities that are perpetuated by the basic structures of our health systems and research modalities, as well as policies that impact access to care and social determinants of health. This scientific statement expands the Society's 2012 statement by focusing on endocrine disease disparities in the pediatric population and sexual and gender minority populations. These include pediatric and adult lesbian, gay, bisexual, transgender, queer, intersex, and asexual (LGBTQIA) persons. The writing group focused on highly prevalent conditions-growth disorders, puberty, metabolic bone disease, type 1 (T1D) and type 2 (T2D) diabetes mellitus, prediabetes, and obesity. Several important findings emerged. Compared with females and non-White children, non-Hispanic White males are more likely to come to medical attention for short stature. Racially and ethnically diverse populations and males are underrepresented in studies of pubertal development and attainment of peak bone mass, with current norms based on European populations. Like adults, racial and ethnic minority youth suffer a higher burden of disease from obesity, T1D and T2D, and have less access to diabetes treatment technologies and bariatric surgery. LGBTQIA youth and adults also face discrimination and multiple barriers to endocrine care due to pathologizing sexual orientation and gender identity, lack of culturally competent care providers, and policies. Multilevel interventions to address these disparities are required. Inclusion of racial, ethnic, and LGBTQIA populations in longitudinal life course studies is needed to assess growth, puberty, and attainment of peak bone mass. Growth and development charts may need to be adapted to non-European populations. In addition, extension of these studies will be required to understand the clinical and physiologic consequences of interventions to address abnormal development in these populations. Health policies should be recrafted to remove barriers in care for children with obesity and/or diabetes and for LGBTQIA children and adults to facilitate comprehensive access to care, therapeutics, and technological advances. Public health interventions encompassing collection of accurate demographic and social needs data, including the intersection of social determinants of health with health outcomes, and enactment of population health level interventions will be essential tools.

Implications of gender-affirming endocrine care for sports participation

Many transgender (trans) individuals utilize gender-affirming hormone therapy (GAHT) to promote changes in secondary sex characteristics to affirm their gender. Participation rates of trans people in sport are exceedingly low, yet given high rates of depression and increased cardiovascular risk, the potential benefits of sports participation are great. In this review, we provide an overview of the evidence surrounding the effects of GAHT on multiple performance-related phenotypes, as well as current limitations. Whilst data is clear that there are differences between males and females, there is a lack of quality evidence assessing the impact of GAHT on athletic performance. Twelve months of GAHT leads to testosterone concentrations that align with reference ranges of the affirmed gender. Feminizing GAHT in trans women increases fat mass and decreases lean mass, with opposite effects observed in trans men with masculinizing GAHT. In trans men, an increase in muscle strength and athletic performance is observed. In trans women, muscle strength is shown to decrease or not change following 12 months of GAHT. Haemoglobin, a measure of oxygen transport, changes to that of the affirmed gender within 6 months of GAHT, with very limited data to suggest possible reductions in maximal oxygen uptake as a result of feminizing GAHT. Current limitations of this field include a lack of long-term studies, adequate group comparisons and adjustment for confounding factors (e.g. height and lean body mass), and small sample sizes. There also remains limited data on endurance, cardiac or respiratory function, with further longitudinal studies on GAHT needed to address current limitations and provide more robust data to inform inclusive and fair sporting programmes, policies and guidelines.

Gender Performance in the Sporting Lives of Young Trans* People

This paper explored how UK trans* youth experienced Physical Education (PE) during secondary school, and its impact on remaining physically active. Seven self-identified trans* people aged 14-25 took part in semi-structured interviews. Findings show participants' performances of gender were restricted by practices privileging the "natural" gender binary. Following school, medical procedures or other physical changes were desired in order to "pass" as their chosen gender before physical activity could occur. Recommendations are presented for improvements to PE policy for trans* youth.

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 (GAHT) is an essential part of gender affirmation for many transgender (including people with binary and nonbinary identities) individuals and although controlled studies are unethical, there remains limited evidence on the impact of GAHT on gender dysphoria, quality of life (QoL), and psychological functioning. Some clinicians and policy makers use the lack of evidence to argue against providing gender-affirming care. The aim of this review is to systematically and critically assess the available literature on the influence of GAHT on improving gender- and body-related dysphoria, psychological well-being, and QoL. Using Preferred Reporting Items for Systematic Review and Meta-analysis guidelines, we searched Ovid MEDLINE®, Embase®, and Ovid PsycINFO® from inception to March 6, 2019 to assess the influence of GAHT on (1) gender dysphoria, (2) body uneasiness, (3) body satisfaction, (4) psychological well-being, (5) QoL, (6) interpersonal and global functioning, and (7) self-esteem. Our search strategy found no randomized controlled trials. Ten longitudinal cohort studies, 25 cross-sectional studies, and 3 articles reporting both cross-sectional and longitudinal data were identified. While results are mixed, the majority of studies demonstrate that GAHT reduces gender dysphoria, body dissatisfaction, and uneasiness, subsequently improving psychological well-being and QoL in transgender individuals. However, all current researches are of low to moderate quality comprising longitudinal cohort studies and cross-sectional studies, making it difficult to draw clear conclusions and do not reflect external social factors unaffected by GAHT, which significantly impact on dysphoria, well-being, and QoL.

Physical Inactivity and the Role of Bullying Among Gender Minority Youth Participating in the 2017 and 2019 Youth Risk Behavior Survey

PURPOSE

Evidence from small-scale studies suggests that transgender youth are less physically active than nontransgender youth, putting them at risk for worse health outcomes. This study examined the relationship between gender modality and participation in physical activity, physical education (PE), and sports teams in a multistate sample of high school youth and assessed whether bullying impacted this relationship.

METHODS

Multiple regression was used to analyze data from the state and local Youth Risk Behavior Survey from 2017 to 2019 to examine the relationship between the gender modality and participation in physical activity, PE, and sports teams. The sample was stratified by sex and adjusted for demographics and in-school and online bullying victimization.

RESULTS

Transgender participants who reported a male or female sex, respectively, reported lower odds of physical activity (adjusted odds ratio [aOR] 0.46, p < .001; aOR 0.46, p < .001, respectively) but similar odds of PE participation. Female transgender students were less likely to participate in sports (aOR 0.55, p = .007); however, this relationship was not seen in adjusted models. Adjusting for demographics, male transgender students were significantly more likely to participate in sports (aOR 2.1, p = .002). Adjusting for bullying experiences did not significantly change these results.

DISCUSSION

Transgender youth are less likely to participate in physical activity but participate similarly or more than cisgender peers in PE and sports. Factors other than bullying may limit physical activity among transgender youth, and the Youth Risk Behavior Survey may not capture experiences of trans-specific victimization. Increased inclusion and safety may help increase physical activity and amplify its benefits for transgender students.

College student aerobic and muscle-strengthening activity: Disparities between cis-gender and transgender students in the United States

Objective: To examine aerobic and muscle-strengthening activity disparities among college cis-gender and transgender students adjusting for other socio-demographic characteristics (age, race/ethnicity, sexual orientation). Methods: National Collegiate Health Assessment (NCHA) data collected between Fall 2015 and Fall 2018 were analyzed using chi-square tests for independence and odds ratios. Results: Cis-gender women were significantly less likely to meet aerobic and muscle-strengthening activity recommendations compared to cisgender men. Transgender men and transgender women were less likely to meet aerobic and muscle-strengthening activity recommendations compared to cisgender peers. Differences were also revealed among transgender individuals, with transgender women more and less likely to meet aerobic and muscle-strengthening recommendations respectively compared to transgender men. Conclusions: Considerable aerobic and muscle-strengthening activity participation disparities exist between cisgender and transgender emerging adults. The unique constraints that transgender college students experience in relation to both aerobic and muscle-strengthening activity participation require further examination to ensure the provision of equitable opportunities to be physically active.

College student aerobic and muscle-strengthening activity: the intersection of gender and race/ethnicity among United States students

Objective: To adopt an intersectional approach to examine differences in aerobic and muscle-strengthening participation based on the intersection of gender and race/ethnicity among college students. Methods: Data from the American College Health Association (ACHA) National College Health Assessment collected between 2015 and 2018 were analyzed. Differences in the prevalence of meeting activity recommendations based on the intersection of gender and race/ethnicity were computed and displayed graphically. Odds of meeting activity recommendations were determined by calculating odds ratios controlling for age, year of enrollment, sexual orientation, and health status. Results: Aerobic and muscle-strengthening activity differed significantly between races within genders, and between genders within races. With minor exceptions, men were more likely to meet aerobic and muscle-strengthening activity recommendations than women of the same race/ethnicity. Disparities based on race varied considerably between genders. Conclusions: The intersection of gender and race/ethnicity should be considered when examining and addressing physical activity disparities.

Disparities in health condition diagnoses among aging transgender and cisgender medicare beneficiaries, 2008-2017

INTRODUCTION

The objective of this research is to provide national estimates of the prevalence of health condition diagnoses among age-entitled transgender and cisgender Medicare beneficiaries. Quantification of the health burden across sex assigned at birth and gender can inform prevention, research, and allocation of funding for modifiable risk factors.

METHODS

Using 2009-2017 Medicare fee-for-service data, we implemented an algorithm that leverages diagnosis, procedure, and pharmacy claims to identify age-entitled transgender Medicare beneficiaries and stratify the sample by inferred gender: trans feminine and nonbinary (TFN), trans masculine and nonbinary (TMN), and unclassified. We selected a 5% random sample of cisgender individuals for comparison. We descriptively analyzed (means and frequencies) demographic characteristics (age, race/ethnicity, US census region, months of enrollment) and used chi-square and t-tests to determine between- (transgender vs. cisgender) and within-group gender differences (e.g., TMN, TFN, unclassified) difference in demographics (p<0.05). We then used logistic regression to estimate and examine within- and between-group gender differences in the predicted probability of 25 health conditions, controlling for age, race/ethnicity, enrollment length, and census region.

RESULTS

The analytic sample included 9,975 transgender (TFN n=4,198; TMN n=2,762; unclassified n=3,015) and 2,961,636 cisgender (male n=1,294,690, female n=1,666,946) beneficiaries. The majority of the transgender and cisgender samples were between the ages of 65 and 69 and White, non-Hispanic. The largest proportion of transgender and cisgender beneficiaries were from the South. On average, transgender individuals had more months of enrollment than cisgender individuals. In adjusted models, aging TFN or TMN Medicare beneficiaries had the highest probability of each of the 25 health diagnoses studied relative to cisgender males or females. TFN beneficiaries had the highest burden of health diagnoses relative to all other groups.

DISCUSSION

These findings document disparities in key health condition diagnoses among transgender Medicare beneficiaries relative to cisgender individuals. Future application of these methods will enable the study of rare and anatomy-specific conditions among hard-to-reach aging transgender populations and inform interventions and policies to address documented disparities.

Sports Medicine Physicians Comfort and Competence in Caring for Transgender and Gender Nonconforming Patients and Athletes

OBJECTIVE

The purpose of this study was to explore primary care sports medicine physicians' comfort, competence, education, and scope of training in caring for transgender and gender nonconforming (TGNC) patients/athletes.

DESIGN

Mixed-methods, cross-sectional survey.

SETTING

Online.

PATIENTS OR PARTICIPANTS

In total, 4300 e-mails were successfully sent with 252 eligible responses received from the American Medical Society for Sports Medicine members.

INDEPENDENT VARIABLES

Previous relationships with TGNC persons; previous relationships with TGNC patients/athletes; frequency of care for TGNC patients/athletes.

MAIN OUTCOME MEASURES

The participants completed a 38-item tool used to assess perceived comfort and competence treating TGNC patients/athletes. Physicians defined "transgender" and described their thoughts on unfair competitive advantage of transgender athletes.

RESULTS

Most participants had worked with a TGNC patient (70.2%, n = 177), but far fewer worked with a TGNC athlete (n = 26.6%, n = 67). Among the participants who provided a definition of transgender (n = 183), only 28.4% (n = 52) of participants were able to correctly define the term, whereas most were able to partially (57.9%, n = 106) characterize the term. The most common mechanisms identified for learning about TGNC patients were reading peer-reviewed journal articles (44.8%, n = 113) and CME (41.3%, n = 104). Those with previous TGNC friend/family, patient, and athlete relationships had a significantly different level of comfort and competence treating TGNC patients/athletes.

CONCLUSIONS

Previous care relationships with TGNC strongly influences comfort and perceived competence of primary care sports medicine physicians. Training, from unbiased peer-reviewed sources of data, is critical to improve care for TGNC patients/athletes.

Transgender Identity and Cardiovascular Disease

Objectives

As of 2016, 1.4 million people in the United States were identified as transgender. Transgender people face health disparities and may be at high risk for cardiovascular disease (CVD). The objective of this study was to examine the odds of CVD for those who report a transgender identity compared with cisgender.

Methods

We used logistic regression to examine whether transgender identity was associated with CVD after accounting for factors commonly associated with CVD. Data were obtained from the Behavioral Risk Factor Surveillance Survey for the years 2015 through 2019.

Results

Of the participants, 93.1% reported no CVD and 6.9% reported CVD. For participants with female sex recorded at birth, those identifying as transgender had 2.66 times higher odds of CVD (95% confidence interval [CI]: 1.60-4.41) than those identifying as cisgender. For participants with male sex recorded at birth, the odds of CVD were not statistically significantly different for transgender identity compared with cisgender identity; however, those who were gender nonconforming had 2.21 times higher odds of CVD (95% CI: 1.04-4.70) compared with those with cisgender identity. Additional significant predictors of CVD were age, race, body mass index, alcohol consumption, exercise, and smoking status.

Conclusion

Participants who were female sex recorded at birth had statistically significant increased odds of CVD for those reporting transgender identity compared with cisgender identity. However, transgender identity did not change the odds of CVD compared with cisgender identity for participants who were male sex recorded at birth.

Multicenter Analysis of Cardiometabolic-related Diagnoses in Transgender and Gender-Diverse Youth: A PEDSnet Study

CONTEXT

Studies on cardiometabolic health in transgender and gender-diverse youth (TGDY) are limited to small cohorts.

OBJECTIVE

This work aimed to determine the odds of cardiometabolic-related diagnoses in TGDY compared to matched controls in a cross-sectional analysis, using a large, multisite database (PEDSnet).

METHODS

Electronic health record data (2009-2019) were used to determine odds of cardiometabolic-related outcomes based on diagnosis, anthropometric, and laboratory data using logistic regression among TGDY youth vs controls. The association of gender-affirming hormone therapy (GAHT) with these outcomes was examined separately among TGDY. TGDY (n = 4172) were extracted from 6 PEDSnet sites and propensity-score matched on 8 variables to controls (n = 16 648). Main outcomes measures included odds of having cardiometabolic-related diagnoses among TGDY compared to matched controls, and among TGDY prescribed GAHT compared to those not prescribed GAHT.

RESULTS

In adjusted analyses, TGDY had higher odds of overweight/obesity (1.2; 95% CI, 1.1-1.3) than controls. TGDY with a testosterone prescription alone or in combination with a gonadotropin-releasing hormone agonist (GnRHa) had higher odds of dyslipidemia (1.7; 95% CI, 1.3-2.3 and 3.7; 95% CI, 2.1-6.7, respectively) and liver dysfunction (1.5; 95% CI, 1.1-1.9 and 2.5; 95% CI, 1.4-4.3) than TGDY not prescribed GAHT. TGDY with a testosterone prescription alone had higher odds of overweight/obesity (1.8; 95% CI, 1.5-2.1) and hypertension (1.6 95% CI, 1.2-2.2) than those not prescribed testosterone. Estradiol and GnRHa alone were not associated with greater odds of cardiometabolic-related diagnoses.

CONCLUSION

TGDY have increased odds of overweight/obesity compared to matched controls. Screening and tailored weight management, sensitive to the needs of TGDY, are needed.

Uncovering the effects of gender affirming hormone therapy on skeletal muscle and epigenetics: protocol for a prospective matched cohort study in transgender individuals (the GAME study)

INTRODUCTION

Gender affirming hormone therapy (GAHT) is increasingly used by transgender individuals and leads to shifts in sex hormone levels. Skeletal muscle is highly responsive to hormone activity, with limited data on the effects of GAHT on different human tissues. Here, we present the protocol for the GAME study (the effects of Gender Affirming hormone therapy on skeletal Muscle training and Epigenetics), which aims to uncover the effects of GAHT on skeletal muscle 'omic' profiles (methylomics, transcriptomics, proteomics, metabolomics) and markers of skeletal muscle health and fitness.

METHODS AND ANALYSIS

This study is a prospective age-matched cohort study in transgender adults commencing GAHT (n=80) and age-matched individuals not commencing GAHT (n=80), conducted at Austin Health and Victoria University in Victoria, Australia. Assessments will take place prior to beginning GAHT and 6 and 12 months into therapies in adults commencing GAHT. Age-matched individuals will be assessed at the same time points. Assessments will be divided over three examination days, involving (1) aerobic fitness tests, (2) muscle strength assessments and (3) collection of blood and muscle samples, as well as body composition measurements. Standardised diets, fitness watches and questionnaires will be used to control for key confounders in analyses. Primary outcomes are changes in aerobic fitness and muscle strength, as well as changes in skeletal muscle DNA methylation and gene expression profiles. Secondary outcomes include changes in skeletal muscle characteristics, proteomics, body composition and blood markers. Linear mixed models will be used to assess changes in outcomes, while accounting for repeated measures within participants and adjusting for known confounders.

ETHICS AND DISSEMINATION

The Austin Health Human Research Ethics Committee (HREC) and Victoria University HREC granted approval for this study (HREC/77146/Austin-2021). Findings from this project will be published in open-access, peer-reviewed journals and presented to scientific and public audiences.

Barriers and Motives for Physical Activity and Sports Practice among Trans People: A Systematic Review

This study aimed to analyze the research conducted between 2016 and 2021, regarding barriers and motives for the practice of physical activity (PA), physical exercise (PE), and sports among trans individuals. The searches were carried out in the PubMed, Scopus, and Web of Science databases between January 2022 and April 2022, and included papers published between October 2016 and December 2021. After reading the full text of the studies, and according to the eligibility criteria previously defined, only six studies met the inclusion criteria. Internal barriers were related to body dissatisfaction and discomfort, discrimination, and fear of other people’s reactions. Regarding external barriers, sports environment, PE environment, and sports participation policies and regulations are the main factors expressed by trans individuals that hinder the practice of sports and PE. The desire to achieve a specific physical form and the role that PE plays in the preparation and/or replacement of gender-confirming surgery are the most important motives for the practice. This study highlights the importance of continuing to fight the barriers encountered in the practice of PE and sports, suggesting the main motives that could help create better interventions, plans, and inclusive policies that may help promote its practice.

Sex Hormone Suppression and Physical Activity: Possible Implications for Transgender Individuals

Purpose

Transgender individuals tend to be less physically active than cisgender individuals, and the primary focus of these physical activity barriers have been psychosocial in nature. Very little attention has been given to the role that changes in the sex hormone milieu (such as that occurring during gender-affirming hormone therapy) play on physical activity. The purpose of this study was to explore the effects of sex hormone suppression using a gonadotropin-releasing hormone agonist (GnRHa) on physical activity levels and patterns.

Methods

Female and male rats received 4 weeks of sex hormone suppression using the GnRHa goserelin acetate (GA) or received a placebo as a control (CON). Animals were then allowed free access to voluntary running wheels, and activity was recorded throughout the treatment period.

Results

Female rats receiving GA (F GA) had a significantly lower total wheel running distance than female CON (F CON, 53±11 km vs. 113±28 km, respectively, p=0.042), and male rats receiving GA (M GA) had a significantly lower total wheel running distance when compared with male CON (M CON, 31±7 km vs. 69±18 km, respectively, p=0.037). Differences in daily wheel running distances were first observed at day 18 between F GA and F CON (p=0.037) and at day 2 between M GA and M CON (p=0.021).

Conclusion

Reduced sex hormone availability reduced wheel running activity in female and male rats. Understanding the role that sex hormone manipulation has on physical activity may be an important consideration in promoting physical activity in transgender individuals receiving treatments that reduce sex hormone availability.

Diet, Food Insecurity, and CVD Risk in Sexual and Gender Minority Adults

Purpose of Review

Sexual and gender minority (SGM) adults experience significant cardiovascular health disparities, yet little is known about diet and food insecurity in this population. This review summarizes recent literature on diet and food insecurity in SGM adults and their contribution to cardiovascular disease (CVD) risk in this population.

Recent Findings

Existing evidence on diet and food insecurity disparities among SGM adults is inconclusive and research examining their link with CVD risk in SGM adults is limited. The majority of existing studies lack standardized and validated assessments of diet and food insecurity. Correlates of unhealthy diet and food insecurity among SGM adults are poorly understood.

Summary

Research examining the associations between diet and food insecurity with CVD risk in SGM adults is limited. Longitudinal studies are needed to investigate whether diet and food insecurity contribute to the cardiovascular health disparities observed in SGM adults.

Cardiovascular Disease Risk Among Transgender People with HIV

PURPOSE OF REVIEW

Transgender individuals are at disproportionate risk for HIV infection, with prevalence rates highest among transgender women of color. Antiretroviral therapy (ART)-treated people with HIV (PWH) are at increased risk for cardiovascular disease (CVD), in relation to persistent systemic immune activation and metabolic dysregulation. The purpose of this review is to examine parameters which may affect CVD risk among transgender PWH.

RECENT FINDINGS

Among transgender women and men, prospective longitudinal studies have shown that gender-affirming hormonal therapy (GAHT) is associated with select deleterious cardiometabolic effects such as increases in visceral adipose tissue. Retrospective studies among transgender women and men suggest an increase in CVD risk, such as venous thromboembolism, cerebrovascular accidents, and myocardial infarction. Studies among transgender PWH adhering to GAHT and ART suggest heightened systemic immune activation/inflammation. Prospective longitudinal studies assessing factors associated with increased CVD events among transgender PWH are needed to guide the development of CVD prevention strategies in this at-risk population.

Assessment of Cardiovascular Risk in Transgender Patients Presenting for Gender-Affirming Care

BACKGROUND

The transgender population is rapidly growing in the United States and abroad. Transgender men and women are marginalized as a result of their transgender status, with resultant health repercussions. This and other factors such as increased substance use, mental health disorders, violence, and chronic stress may place transgender individuals at higher risk for cardiovascular disease. Additionally, many transgender patients pursue gender-affirming hormone therapy, which has been linked to increased rates of some cardiovascular events such as metabolic syndrome, venous thromboembolism, and stroke. Despite the likelihood of elevated cardiovascular risk in this population, there is a paucity of published data about the cardiovascular risk of this population.

METHODS

We present baseline cardiovascular data from a transgender population at a large tertiary care center prior to the initiation of hormone therapy.

RESULTS

The described transgender population had much higher rates of mental health disorders and substance use than the general population. Furthermore, there were high rates of undiagnosed and untreated comorbidities, such as hypertension and dyslipidemia, that increase risk for cardiovascular disease. Baseline risk assessment using the ASCVD (Atherosclerotic Cardiovascular Disease) and QRISK3 calculators showed higher-than-expected cardiovascular risk, particularly given the young age of our patient population.

CONCLUSIONS

Transgender individuals are at high baseline cardiovascular risk. These data help fill some important knowledge gaps in this patient subgroup, and provide us with much-needed data to help guide our management and counseling of individuals seeking this type of care.

Assessing and Addressing Cardiovascular Health in People Who Are Transgender and Gender Diverse: A Scientific Statement From the American Heart Association

There is growing evidence that people who are transgender and gender diverse (TGD) are impacted by disparities across a variety of cardiovascular risk factors compared with their peers who are cisgender. Prior literature has characterized disparities in cardiovascular morbidity and mortality as a result of a higher prevalence of health risk behaviors. Mounting research has revealed that cardiovascular risk factors at the individual level likely do not fully account for increased risk in cardiovascular health disparities among people who are TGD. Excess cardiovascular morbidity and mortality is hypothesized to be driven in part by psychosocial stressors across the lifespan at multiple levels, including structural violence (eg, discrimination, affordable housing, access to health care). This American Heart Association scientific statement reviews the existing literature on the cardiovascular health of people who are TGD. When applicable, the effects of gender-affirming hormone use on individual cardiovascular risk factors are also reviewed. Informed by a conceptual model building on minority stress theory, this statement identifies research gaps and provides suggestions for improving cardiovascular research and clinical care for people who are TGD, including the role of resilience-promoting factors. Advancing the cardiovascular health of people who are TGD requires a multifaceted approach that integrates best practices into research, health promotion, and cardiovascular care for this understudied population.

Does Gender-Affirming Hormonal Treatment Affect 30-Year Cardiovascular Risk in Transgender Persons? A Two-Year Prospective European Study (ENIGI)

BACKGROUND

Cardiovascular (CV) implications of long-term gender affirming hormonal treatment (GAHT) in transgender individuals still remain largely unknown.

AIM

To evaluate changes in the 30-year Framingham cardiovascular disease (CVD) risk in a large cohort of transgender individuals after the start of GAHT.

METHODS

In a multicenter prospective study, a consecutive series of 309 participants (165 transmen and 144 transwomen) was evaluated during a 2-year follow-up. Prospectively, after the start of GAHT a physical examination was performed and blood samples were drawn. CVD risk was calculated for each person, according to the Framingham 30-year CVD risk estimate.

MAIN OUTCOME MEASURE

Changes in CV risk factors and 30-year Framingham CVD risk during GAHT.

CLINICAL IMPLICATIONS

In transmen testosterone-induced lipid profile alterations may have a clinical relevance on the individual long-term CVD risk.

STRENGTHS & LIMITATIONS

The strength of the present study is the possibility to predict long-term CV outcomes in transgender individuals receiving GAHT based on a short observation; whereas the main limitation is that CVD risk prospective changes mainly represent the expression of risk factors changes during GAHT.

RESULTS

In transwomen a significant decrease in triglycerides, total cholesterol and LDL-cholesterol was observed during the 2-year follow-up (P < .05), whereas unfavorable lipid changes - such as increased total cholesterol, triglycerides, and LDL cholesterol levels and decreased HDL cholesterol levels (P < .05)- occurred after the start of GAHT in transmen. These changes in risk factors led to an increase in the risk of general and hard CVD events based on lipid profile over time in transmen (P = .001 and P = .005, respectively). No significant changes in general and hard CVD risk based on lipid profile were observed in transwomen over time.

CONCLUSIONS

Our findings confirmed the unfavorable lipid changes in transmen after the start of GAHT even during a longer follow-up, empathizing the potential clinical impact of these modifications on individual long-term CVD risk.

College Student Aerobic and Muscle-Strengthening Activity: The Intersection of Gender and Sexual Orientation Among United States Students

The purpose of the study was to examine differences in aerobic and muscle-strengthening activity participation based on the intersection of gender and sexual orientation among cisgender college students. Data from the American College Health Association National College Health Assessment collected between Fall 2015 and Fall 2018 were analyzed. Differences from the population average for meeting aerobic and muscle-strengthening activity (separately) recommendations were computed for each gender and sexual orientation intersection. The likelihood of meeting aerobic and muscle-strengthening activity (separately) recommendations were calculated using a series of logistic regression analyses to determine odds ratios controlling for age, year of enrollment, race/ethnicity, and health status. Overall, more men and those identifying as straight met activity (aerobic and muscle-strengthening) recommendations. Asexual and straight women were less likely to meet activity recommendations compared to men, and bisexual and questioning women were less likely to meet muscle-strengthening recommendations compared to men. Bisexual, pansexual, and questioning individuals were less likely to meet activity recommendations compared to straight individuals among both genders, as were queer and gay men and women who identified as pansexual or another identity. Men who identified as pansexual or another identity, as well as lesbian and queer women were less likely to meet muscle-strengthening recommendations compared to straight individuals. In summary, findings demonstrate that aerobic and muscle-strengthening activity participation disparities are evident based on the intersection of gender and sexual orientation. The intersection of socio-demographic characteristics should be considered by researchers and physical activity promoters in order to better understand and address disparities.

Orthopaedic Care of the Transgender Patient

»

A transgender person is defined as one whose gender identity is incongruent with their biological sex assigned at birth. This highly marginalized population numbers over 1.4 million individuals in the U.S.; this prevalence skews more heavily toward younger generations and is expected to increase considerably in the future.

»

Gender-affirming hormone therapy (GAHT) has physiologic effects on numerous aspects of the patient's health that are pertinent to the orthopaedic surgeon, including bone health, fracture risk, and perioperative risks such as venous thromboembolism and infection.

»

Language and accurate pronoun usage toward transgender patients can have a profound effect on a patient's experience and on both objective and subjective outcomes.

»

Gaps in research concerning orthopaedic care of the transgender patient are substantial. Specific areas for further study include the effects of GAHT on fracture risk and healing, outcome disparities and care access across multiple subspecialties, and establishment of perioperative management guidelines.

Physical and Sociodemographic Features Associated With Quality of Life Among Transgender Women and Men Using Gender-Affirming Hormone Therapy

Background: Gender dysphoria is defined as a feeling of distress resulting from the incongruence between the sex assigned at birth and the gender identity, lasting longer than 6 months. In individuals with gender dysphoria, gender-affirming hormone therapy (GAHT) may improve quality of life (QoL). Objectives: We aimed to assess perceived QoL, to compare QoL scores between trans women and men and to identify possible contributing factors related to GAHT in a sample of transgender women and transgender men. Methods: In this cross-sectional study, transgender women and men were recruited by availability sampling from a national transgender health service. Individuals over 18 years old with a confirmed diagnosis of gender dysphoria receiving medically prescribed GAHT for at least 6 months were consecutively included. Also included were trans men who had undergone mastectomy and trans women who had received breast augmentation surgery. Individuals who had undergone gender affirmation surgery (specifically genital surgery) or with uncontrolled clinical/psychiatric conditions at the time of the initial assessment were excluded. Sociodemographic, physical, and hormone data were collected from all participants. The WHOQOL-BREF questionnaire was used to evaluate QoL. A total of 135 transgender individuals were invited. Seventeen individuals with previous genital surgery (12.6%) and five who refused to participate (3.7%) were excluded. Therefore, 113 patients were enrolled and completed the study (60 trans women and 53 trans men). Results: QoL scores did not differ between trans women and trans men. In trans women, greater breast development and stable relationships, and higher body mass index were associated with higher QoL domain scores. In trans men, higher domain scores were found in individuals in a stable relationship, with increased body hair, engaging in physical activity, and being employed. Conclusion: Data from this study suggest that GAHT-related physical characteristics, such as breast development in trans women and increased body hair in trans men, are similar between groups, are associated with higher QoL scores, and that sociodemographic parameters may impact these associations. Healthcare providers might consider these factors when planning interventions to improve QoL in transgender individuals.

Assessing and Addressing Cardiovascular Health in LGBTQ Adults: A Scientific Statement From the American Heart Association

There is mounting evidence that lesbian, gay, bisexual, transgender, and queer or questioning (LGBTQ) adults experience disparities across several cardiovascular risk factors compared with their cisgender heterosexual peers. These disparities are posited to be driven primarily by exposure to psychosocial stressors across the life span. This American Heart Association scientific statement reviews the extant literature on the cardiovascular health of LGBTQ adults. Informed by the minority stress and social ecological models, the objectives of this statement were (1) to present a conceptual model to elucidate potential mechanisms underlying cardiovascular health disparities in LGBTQ adults, (2) to identify research gaps, and (3) to provide suggestions for improving cardiovascular research and care of LGBTQ people. Despite the identified methodological limitations, there is evidence that LGBTQ adults (particularly lesbian, bisexual, and transgender women) experience disparities across several cardiovascular health metrics. These disparities vary by race, sex, sexual orientation, and gender identity. Future research in this area should incorporate longitudinal designs, elucidate physiological mechanisms, assess social and clinical determinants of cardiovascular health, and identify potential targets for behavioral interventions. There is a need to develop and test interventions that address multilevel stressors that affect the cardiovascular health of LGBTQ adults. Content on LGBTQ health should be integrated into health professions curricula and continuing education for practicing clinicians. Advancing the cardiovascular health of LGBTQ adults requires a multifaceted approach that includes stakeholders from multiple sectors to integrate best practices into health promotion and cardiovascular care of this population.

Physical Activity and Sport in Trans Persons Before and After Gender Disclosure: Prevalence, Frequency, and Type of Activities

BACKGROUND

This study describes the prevalence, frequency, and type of physical activity and sport (PAS) practiced by trans persons before and after their gender disclosure (GD).

METHODS

A face-to-face survey was administered to 212 Spanish trans persons, aged from 10 to 62 years old. McNemar and chi-square tests were used to determine significant differences.

RESULTS

About 75.5% of the trans persons in this study engaged in PAS and more than 50% did so ≥3 times/week, which is similar as in the general Spanish population. Participation was higher in trans men (78.7%) than trans women (72%). However, GD emerges as a key issue in characterizing trans persons' PAS participation. A group of 14.5% of them stopped activity after GD. Participation in nonorganized PAS was higher than in organized PAS, and this difference is greater after GD because most participants gave up organized PAS in favor of nonorganized PAS. Trans persons preferred individual sports and activities than team sports before and after GD, and the top 3 activities were jogging, walking, and bodybuilding. Trans men participation was higher than trans women in team PAS, whereas individual PAS were equally practiced before and after GD. Participation in football, swimming, basketball, dancing, and volleyball declined after GD, whereas bodybuilding increased in trans men.

CONCLUSIONS

The results show that the high involvement of trans persons coincides with strategies used to hide or conceal their gender identities when participating in PAS. A decrease in PAS participation is observed after GD probably because it is an acute potential period of anxiety, discrimination, and victimization caused by trans persons' body exposure.

Assessing gender identity differences in cardiovascular disease in US adults: an analysis of data from the 2014-2017 BRFSS

The purpose of this study was to assess gender identity differences in CVD risk and CVD conditions among adults in the U.S. Using data from the 2014-2017 BRFSS we compared CVD risk and CVD conditions in gender minorities (transgender men, transgender women and gender nonconforming persons) to both cisgender men and women. The sample consisted of 662,903 participants. Transgender women (AOR 1.34, 95% CI 1.05-1.72) and transgender men (AOR 1.54, 95% CI 1.07-2.24) were more likely to be overweight than cisgender women. Compared to cisgender women, transgender women reported higher rates of diabetes (AOR 1.45, 95% CI 1.05-1.99), angina/coronary heart disease (AOR 1.90, 95% CI 1.34-2.68), stroke (AOR 1.88, 95% CI 1.16-3.03), and myocardial infarction (AOR 2.98, 95% CI 2.14-4.17). Gender nonconforming participants (AOR 2.68, 95% CI 1.14-6.30) reported higher odds of myocardial infarction than cisgender women. Transgender women also had higher rates of reporting any CVD than cisgender men (AOR 1.38, 95% CI 1.01-1.88). There is a need to elucidate the cardiovascular effects of minority stressors and gender affirming therapy in this population. More research focused on CVD prevention and management in gender minorities is recommended.

Transgender individuals' cancer survivorship: Results of a cross-sectional study

BACKGROUND

Transgender individuals' cancer prevalence and transgender cancer survivors' health needs have received scarce attention. The current study compared transgender and cisgender individuals' cancer prevalence and described the health needs of transgender cancer survivors.

METHODS

The authors used Behavioral Risk Factor Surveillance System data on 95,800 cisgender and transgender individuals who self-reported a cancer diagnosis. Using multiple logistic regression, they estimated cancer prevalence and calculated odds ratios with 95% confidence intervals of physical, psychological, overall health, and health behaviors of transgender survivors compared with cisgender survivors.

RESULTS

After adjusting for confounders, transgender men had a significantly higher (>2-fold) number of cancer diagnoses compared with cisgender men, but not cisgender women. Cancer prevalence among gender nonconforming individuals and transgender women was not significantly different from that of cisgender men and cisgender women. Gender nonconforming survivors had significantly greater physical inactivity, heavy episodic alcohol use, and depression compared with cisgender men and cisgender women. Transgender men survivors were significantly more likely to report poor physical health and greater medical comorbidities and were less likely to report smoking compared with cisgender men and cisgender women. Transgender women survivors were significantly more likely to report diabetes compared with cisgender men and cisgender women and were more likely to report cardiovascular disease compared with cisgender women.

CONCLUSIONS

Clinicians should be aware of the higher prevalence of cancer among transgender men and a potential survivorship bias among transgender individuals. Transgender survivors have considerable variation in their risk profile. Clinicians and health services can target gender nonconforming survivors' depression and health behaviors to improve survival and should address the complex comorbidities of transgender men and transgender women.

Physical activity and body image: Intertwined health priorities identified by transmasculine young people in a non-metropolitan area

Background: A dearth of research exists about the health behaviors of transgender young people (TYP). As we seek to learn more about transgender (trans) health, community-based participatory research (CBPR) approaches are crucial for incorporating TYP's needs into the formulation of research questions and development of health behavior programing. Aim: Explore body image and exercise as priorities among TYP. Methods: Trans masculine young adults (N = 16) in a small city in the Midwest took part in semi-structured interviews about their health behaviors and priorities. Theme analysis was used to capture key patterns in participants' responses. Specific analysis steps included initial and more specific coding, analytical memos, organizational matrices and reports, and discussion about results with participants. Results: Participants identified exercise and body image as connected primary health concerns. They discussed these issues in terms of three themes: Body shape as motivation for exercise; Poor body image, stigma and fear as exercise barriers, and; Exercise or lack of, as destructive. Participants wanted to exercise to achieve a certain body shape, not for health or as stress relief. They cited gyms as unwelcoming, however. They also worried about discrimination and did not feel sufficiently comfortable with their bodies to exercise. When they could not exercise, they used harmful behaviors, like restricted eating, to achieve a specific male shape. Conclusions: Using participatory methods allowed us to understand the priorities of a group of Transmasculine young people. Our findings suggest that it is important to continue to explore TYP's body-related motivations for exercise and understand the balance between exercise as a positive health behavior, and a potentially harmful one, in light of TYP's complex body image concerns. Trans friendly gyms and gym policies could promote safe exercise and continued anti trans discrimination work and policy advocacy can promote the safety of TYP in all spaces.

Osteoporosis and Bone Health in Transgender Persons

This review summarizes current studies, systematic reviews, and clinical practice guidelines regarding the screening, diagnosis, and treatment of osteoporosis in transgender persons. Gender-affirming hormone therapy has been shown to maintain or promote acquisition of bone density as measured by dual-energy x-ray absorptiometry. No differences in fracture rates have been seen in trans women or men in short, prospective trials. Trans children and adolescents on gonadotropin-releasing hormone may be at risk for decreasing bone density while not on sex steroid hormone replacement. Screening for osteoporosis should be based on clinical factors. Treatment for osteoporosis follows the same guidelines as cisgender populations.

Cardiometabolic Effects of Testosterone in Transmen and Estrogen Plus Cyproterone Acetate in Transwomen

CONTEXT

The impact of gender-affirming hormone therapy (HT) on cardiometabolic parameters is largely unknown.

OBJECTIVE

The effects of 1 year of treatment with oral or transdermal administration of estrogen (plus cyproterone) and transdermal or IM application of testosterone on serum lipid levels and blood pressure (BP) were assessed in transgender persons.

DESIGN AND METHODS

In this prospective, observational substudy of the European Network for the Investigation of Gender Incongruence, measurements were performed before and after 12 months of HT in 242 transwomen and 188 transmen from 2010 to 2017.

RESULTS

Mean values are reported. In transmen, HT increased diastolic BP (2.5%; 95% CI, 0.6 to 4.4) and levels of total cholesterol (TC; 4.1%; 95% CI, 1.5 to 6.6), low-density lipoprotein-cholesterol (LDL-C; 13.0%; 95% CI, 9.2 to 16.8), and triglycerides (36.9%; 95% CI, 29.8 to 44.1); high-density lipoprotein-cholesterol levels decreased (HDL-C; 10.8%; 95% CI, -14.0 to -7.6). In transwomen, HT slightly decreased BP (systolic BP, -2.6%, 95% CI, -4.2 to -1.0; diastolic BP, -2.2%, 95% CI, -4.0 to -0.4) and decreased levels of TC (-9.7%; 95% CI, -11.3 to -8.1), LDL-C (-6.0%; 95% CI, -8.6 to 3.6), HDL-C (-9.3%; 95% CI, -11.4 to -7.3), and triglycerides (-10.2%; 95% CI, -14.5 to -5.9).

CONCLUSION

Unfavorable changes in lipid profile were observed in transmen; a favorable effect was noted in transwomen. HT effects on BP were negligible. Long-term studies are warranted to assess whether and to what extent HT in trans individuals results in a differential effect on cardiovascular disease outcomes.

Gender congruence and body satisfaction in nonbinary transgender people: A case control study

Background: Binary transgender people access gender affirming medical interventions to alleviate gender incongruence and increase body satisfaction. Despite the increase in nonbinary transgender people, this population are less likely to access transgender health services compared to binary transgender people. No research has yet understood why by exploring levels of gender congruence and body satisfaction in nonbinary transgender people. Objective: The aim of this study was to compare levels of gender congruence and body satisfaction in nonbinary transgender people to controls [binary transgender people and cisgender (nontrans) people]. Method: In total, 526 people from a community sample in the UK took part in the study (97 nonbinary, 91 binary, and 338 cisgender identifying people). Participants were asked to complete an online survey about gender congruence and body satisfaction. Results: There were differences in gender congruence and body satisfaction between nonbinary and binary transgender people. On sex-specific parts of the body (i.e., chest, genitalia, and secondary sex characteristics), nonbinary transgender people reported significantly higher levels of gender and body satisfaction compared to binary transgender people. However, there was no difference in congruence and satisfaction with social gender role between the two transgender groups (nonbinary and binary). Cisgender people reported significantly higher levels of gender congruence and body satisfaction compared to transgender people (nonbinary and binary). Conclusions: There are differences in gender congruence and body satisfaction between nonbinary and binary transgender people. Nonbinary individuals may be less likely to access transgender health services due to experiencing less gender incongruence and more body satisfaction compared to binary transgender people. Transgender health services need to be more inclusive of nonbinary transgender people and their support and treatment needs, which may differ from those who identify within the binary gender system.

Gender-specific considerations in physical activity, thermogenesis and fat oxidation: implications for obesity management

With current 'one-size-fits-all' obesity prevention and management strategies proving largely ineffective, the focus has shifted towards a more tailored, individualized approach. However, investigation of the mechanisms underlying inter-individual variability in metabolic profile and response to intervention often yield conflicting results. Indeed, it is perhaps surprising that despite at least a century of recognition that sex hormones influence metabolism, firm conclusions regarding the effects of the menstrual cycle, hormonal contraception and menopause on many aspects of energy expenditure and substrate utilization remain to be drawn. In this review, we examine current evidence relating to gender-specific considerations in the promotion of physical activity, thermogenesis and fat oxidation for body-weight regulation, including the relationship between sex hormone status and non-exercise activity thermogenesis - an energy expenditure compartment that is often overlooked in favour of traditional exercise/sport physical activities yet presents a viable target in the search for effective weight management.

Quality of life of treatment-seeking transgender adults: A systematic review and meta-analysis

The study aims to systematically extract and analyse data about Quality of Life (QoL) in the transgender population. A systematic literature search and meta-analysis were conducted using the MEDLINE, EMBASE, PubMed, and PsycINFO databases, up to July 2017. Only English language quantitative studies, in adults, which reported the means for validated QoL measures were included. Random-effect meta-analysis was adopted to pool data and estimate the 95% Confidence Intervals (CI). From 94 potentially relevant articles, 29 studies were included within the review and data extraction for meta-analysis was available in 14 studies. The majority of the studies were cross-sectional, lacked controls and displayed moderate risk of bias. Findings from the systematic review suggested that transgender people display poor QoL, independent of the domain investigated. Pooling across studies showed that transgender people report poorer mental health QoL compared to the general population (-0.78, 95% CI = -1.08 to -0.48, 14 studies). However, meta-analysis in a subgroup of studies looking at QoL in participants who were exclusively post-CHT found no difference in mental health QoL between groups (-0.42, 95% CI = -1.15 to 0.31; 7 studies). There was insufficient data for a pre-treatment subgroup. Evidence suggests that transgender people have lower QoL than the general population. Some evidence suggests that QoL improves post-treatment. Better quality studies that include clearly defined transgender populations, divided by stage of gender affirming treatment and with appropriate matched control groups are needed to draw firmer conclusions.
