Evaluation and medical care of intersex and gender diverse youth. Pediatr Radiol 2024:10.1007/s00247-024-05948-y. [PMID: 38782777 DOI: 10.1007/s00247-024-05948-y] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 03/18/2024] [Revised: 05/03/2024] [Accepted: 05/07/2024] [Indexed: 05/25/2024]
Abstract
While there is considerable overlap in the treatment of patients with intersex traits and differences in sex development (I/DSD) with transgender and gender diverse (TGD) youth, the initial medical evaluation varies significantly. I/DSD youth often present due to differences in genitalia development in infancy or pubertal development in adolescence, and this leads to comprehensive biochemical, radiologic, and genetic evaluation. TGD youth, however, tend to have typical development noted at birth and during puberty, but present with a gender identity that does not align with their sex assigned at birth and do not require evaluation for underlying pathology. For both I/DSD and TGD youth, the mainstays of treatment are to better align one's physical appearance to their gender identity. This review discusses the non-medical and medical interventions utilized in gender affirming care. A multidisciplinary team of mental health providers, pediatric medical providers, and surgeons is recommended for providing gender affirming care to both I/DSD youth and TGD youth and their families. Radiologists have an important role in initial evaluation of I/DSD youth and in ongoing monitoring of growth and bone mineral density during puberty induction in I/DSD and TGD youth.

Puberty Suppression for Pediatric Gender Dysphoria and the Child's Right to an Open Future. ARCHIVES OF SEXUAL BEHAVIOR 2024; 53:1941-1956. [PMID: 38565790 PMCID: PMC11106199 DOI: 10.1007/s10508-024-02850-4] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Subscribe] [Scholar Register] [Received: 10/13/2022] [Revised: 03/03/2024] [Accepted: 03/04/2024] [Indexed: 04/04/2024]
Abstract
In this essay, we consider the clinical and ethical implications of puberty blockers for pediatric gender dysphoria through the lens of "the child's right to an open future," which refers to rights that children do not have the capacity to exercise as minors, but that must be protected, so they can exercise them in the future as autonomous adults. We contrast the open future principle with the beliefs underpinning the gender affirming care model and discuss implications for consent. We evaluate claims that puberty blockers are reversible, discuss the scientific uncertainty about long-term benefits and harms, summarize international developments, and examine how suicide has been used to frame puberty suppression as a medically necessary, lifesaving treatment. In discussing these issues, we include relevant empirical evidence and raise questions for clinicians and researchers. We conclude that treatment pathways that delay decisions about medical transition until the child has had the chance to grow and mature into an autonomous adulthood would be most consistent with the open future principle.

No Bones About It: Sex Is Binary. ARCHIVES OF SEXUAL BEHAVIOR 2024; 53:1595-1608. [PMID: 38565789 DOI: 10.1007/s10508-024-02851-3] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Subscribe] [Scholar Register] [Received: 12/05/2023] [Revised: 03/02/2024] [Accepted: 03/04/2024] [Indexed: 04/04/2024]
Abstract
Anthropologists have led the way in formulating techniques that reveal skeletal differences between males and females. Understanding of physical differences in the pelvis related to childbirth, hormonal impacts on bones, and extensive comparative studies have provided anthropologists with an array of traits and measurements that help them estimate sex using just bones. Forensic anthropologists and bioarcheologists are improving their ability to differentiate males and females by increasing research on a variety of postcranial bones and through the use of molecular data, especially new methods called proteomics, to identify sex in prepubescent juveniles. As remains from more cultures and time periods are studied, sex identification will continue to improve, because skeletal sex differences are in large part biologically determined. Yet, anthropologists have also been at the forefront of arguing that sex lies on a spectrum. Anthropologists who view sex as on a spectrum may deter sex identification progress; from their perspective, an individual of an undetermined sex may just be a nonbinary individual. Anthropologists who consider sex is on a spectrum are coming to this conclusion in part because they are looking for anatomical ideals, mistaking pathology for variation, and confusing independent variables with dependent variables. Nonetheless, anthropologists need to continue to improve sex identification techniques to reconstruct the past accurately, which may reveal less strict sex roles than previously presumed and help with the identification of crime victims. Forensic anthropologists should also increase their efforts to identify whether individuals have undergone medical procedures intended to change one's gender due to the current rise in transitioning individuals.

Adolescent gender dysphoria management: position paper from the Italian Academy of Pediatrics, the Italian Society of Pediatrics, the Italian Society for Pediatric Endocrinology and Diabetes, the Italian Society of Adolescent Medicine and the Italian Society of Child and Adolescent Neuropsychiatry. Ital J Pediatr 2024; 50:73. [PMID: 38637868 PMCID: PMC11025175 DOI: 10.1186/s13052-024-01644-7] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 02/28/2024] [Accepted: 04/05/2024] [Indexed: 04/20/2024] Open
Abstract
BACKGROUND In response to the imperative need for standardized support for adolescent Gender Dysphoria (GD), the Italian Academy of Pediatrics, in collaboration with the Italian Society of Pediatrics, the Italian Society for Pediatric Endocrinology and Diabetes, Italian Society of Adolescent Medicine and Italian Society of Child and Adolescent Neuropsychiatry is drafting a position paper. The purpose of this paper is to convey the author's opinion on the topic, offering foundational information on potential aspects of gender-affirming care and emphasizing the care and protection of children and adolescents with GD. MAIN BODY Recognizing that adolescents may choose interventions based on their unique needs and goals and understanding that every individual within this group has a distinct trajectory, it is crucial to ensure that each one is welcomed and supported. The approach to managing individuals with GD is a multi-stage process involving a multidisciplinary team throughout all phases. Decisions regarding treatment should be reached collaboratively by healthcare professionals and the family, while considering the unique needs and circumstances of the individual and be guided by scientific evidence rather than biases or ideologies. Politicians and high court judges should address discrimination based on gender identity in legislation and support service development that aligns with the needs of young people. It is essential to establish accredited multidisciplinary centers equipped with the requisite skills and experience to effectively manage adolescents with GD, thereby ensuring the delivery of high-quality care. CONCLUSION Maintaining an evidence-based approach is essential to safeguard the well-being of transgender and gender diverse adolescents.

Abstract
Some transgender youth are treated with gonadotropin-releasing hormone agonists (GnRHa) followed by testosterone or estradiol, which may impact bone mineral density (BMD). This cross-sectional study of transgender youth (n = 56, aged 10.4-19.8 years, 53% assigned female at birth [AFAB]) utilized total body dual-energy x-ray absorptiometry to evaluate BMD Z-scores, and associations between GnRHa duration, body mass index (BMI), and BMD. Participants on GnRHa alone (n = 19, 14 assigned male at birth [AMAB], 5 AFAB) at the time of the study visit were 13.8 [12.8, 15.3] (median [IQR]) years old, had been on GnRHa for 10 [5.5, 19.5] months, and began GnRHa at age 12 [10.4, 12.6] years. Total body BMD Z-score for individuals on GnRHa monotherapy was -0.10 [-0.8, 0.4] (AFAB, female norms) and -0.65 [-1.4, 0.22] (AMAB, male norms). AFAB participants (n = 21) on testosterone were age 16.7 [15.9, 17.8] years, had been on testosterone for 11 [7.3, 14.5] months, and started testosterone at age 16 [14.8, 16.8] years; total body BMD Z-score -0.2 [-0.5, 0] (male norms) and 0.4 [-0.2, 0.7] (female norms). AMAB participants (n = 16) were age 16.2 [15.1, 17.4] years, had been on estradiol for 11 [5.6, 13.7] months, and started estradiol at age 16 [14.4, 16.7] years; total body BMD Z-score -0.4 [-1.1, 0.3] (male norms) and -0.2 [-0.7, 0.6] (female norms). BMD Z-score was negatively correlated with GnRHa duration (male norms: r = -0.5, P = .005; female norms: r = -0.4, P = .029) and positively correlated with BMI (male norms: r = 0.4, P = .003; female norms: r = 0.4, P = .004). In this cross-sectional cohort, total body BMD Z-scores were slightly below average, but lowest in the AMAB group on GnRHa monotherapy.

Abstract
Gender-affirming care (GAC) acknowledges the right of each individual to live in the gender that is most authentic to them and to receive nonjudgmental, developmentally appropriate care. For transgender and gender-diverse (TGD) individuals, this care may include transition-related care, such as puberty blockers, gender-affirming hormones, and therapies, including surgery. All youth, including TGD youth, deserve confidential, adolescent-friendly care. However, recent legislation in many states seeks to limit access and/or ban GAC for TGD youth. This article reviews the evidence supporting GAC for adolescents, the risk of denying this care, and recommendations for advocacy from all pediatric-focused clinicians.

Abstract
PURPOSE Preliminary data suggested that bone mineral density (BMD) in transgender adults before initiating gender-affirming hormone therapy (GAHT) is lower when compared to cisgender controls. In this study, we analyzed bone metabolism in a sample of transgender adults before GAHT, and its possible correlation with biochemical profile, body composition and lifestyle habits (i.e., tobacco smoke and physical activity). METHODS Medical data, smoking habits, phospho-calcic and hormonal blood tests and densitometric parameters were collected in a sample of 125 transgender adults, 78 Assigned Females At Birth (AFAB) and 47 Assigned Males At Birth (AMAB) before GAHT initiation and 146 cisgender controls (57 females and 89 males) matched by sex assigned at birth and age. 55 transgender and 46 cisgender controls also underwent a complete body composition evaluation and assessment of physical activity using the International Physical Activity Questionnaire (IPAQ). RESULTS 14.3% of transgender and 6.2% of cisgender sample, respectively, had z-score values < -2 (p = 0.04). We observed only lower vitamin D values in transgender sample regarding biochemical/hormonal profile. AFAB transgender people had more total fat mass, while AMAB transgender individuals had reduced total lean mass as compared to cisgender people (53.94 ± 7.74 vs 58.38 ± 6.91, p < 0.05). AFAB transgender adults were more likely to be active smokers and tend to spend more time indoor. Fat Mass Index (FMI) was correlated with lumbar and femur BMD both in transgender individuals, while no correlations were found between lean mass parameters and BMD in AMAB transgender people. CONCLUSIONS Body composition and lifestyle factors could contribute to low BMD in transgender adults before GAHT.

Abstract
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.

A systematic review of hormone treatment for children with gender dysphoria and recommendations for research. Acta Paediatr 2023; 112:2279-2292.

Abstract
AIM The aim of this systematic review was to assess the effects on psychosocial and mental health, cognition, body composition, and metabolic markers of hormone treatment in children with gender dysphoria. METHODS Systematic review essentially follows PRISMA. We searched PubMed, EMBASE and thirteen other databases until 9 November 2021 for English-language studies of hormone therapy in children with gender dysphoria. Of 9934 potential studies identified with abstracts reviewed, 195 were assessed in full text, and 24 were relevant. RESULTS In 21 studies, adolescents were given gonadotropin-releasing hormone analogues (GnRHa) treatment. In three studies, cross-sex hormone treatment (CSHT) was given without previous GnRHa treatment. No randomised controlled trials were identified. The few longitudinal observational studies were hampered by small numbers and high attrition rates. Hence, the long-term effects of hormone therapy on psychosocial health could not be evaluated. Concerning bone health, GnRHa treatment delays bone maturation and bone mineral density gain, which, however, was found to partially recover during CSHT when studied at age 22 years. CONCLUSION Evidence to assess the effects of hormone treatment on the above fields in children with gender dysphoria is insufficient. To improve future research, we present the GENDHOR checklist, a checklist for studies in gender dysphoria.

Abstract
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.

Abstract
PURPOSE OF REVIEW The purpose of this review is to summarize the scientific evidence on bone health in transgender and gender diverse (TGD) youth. RECENT FINDINGS Gender-affirming medical therapies may be introduced during a key window of skeletal development in TGD adolescents. Before treatment, low bone density for age is more prevalent than expected in TGD youth. Bone mineral density Z-scores decrease with gonadotropin-releasing hormone agonists and differentially respond to subsequent estradiol or testosterone. Risk factors for low bone density in this population include low body mass index, low physical activity, male sex designated at birth, and vitamin D deficiency. Peak bone mass attainment and implications for future fracture risk are not yet known. TGD youth have higher than expected rates of low bone density prior to initiation of gender-affirming medical therapy. More studies are needed to understand the skeletal trajectories of TGD youth receiving medical interventions during puberty.

Abstract
ABSTRACT The field of transgender health has grown exponentially since the early 2010s. While this increased visibility has not been without controversy, there is growing acknowledgement of the needs of transgender, nonbinary, and gender expansive (TNG) patients and the health disparities they experience compared to the cisgender population. There is also increased interest among clinicians and trainees in providing gender-affirming care in all medical specialties. This is particularly relevant in psychiatry as mental health disparities in TNG patients have been well-documented. TNG patients experience significant minority stress and higher rates of psychiatric illness, self-harm, suicidality, and psychiatric hospitalization compared to their cisgender peers. In this review, we will cover potential interactions and side effects relevant to psychiatric medication management for the three most common medication classes prescribed as part of gender-affirming hormone therapy (GAHT): gonadotropin-releasing hormone receptor agonists, estradiol, and testosterone. Although no studies directly examining the efficacy of psychiatric medications or their interactions with GAHT for TNG patients have been published yet, we have synthesized the existing literature from both cisgender and TNG patients to shed light on health care disparities seen in TNG patients. Since clinicians' lack of comfort and familiarity with gender-affirming care contributes significantly to these disparities, we hope this narrative review will help psychiatric prescribers provide TNG patients with the same quality of care that cisgender patients receive.

Abstract
Increasing numbers of transgender and gender-diverse (TGD) youth, from early puberty through late adolescence, are seeking medical services to bring their physical sex characteristics into alignment with their gender identity-their inner sense of self as male or female or elsewhere on the gender spectrum. Numerous studies, primarily of short- and medium-term duration (up to 6 years), demonstrate the clearly beneficial-even lifesaving-mental health impact of gender-affirming medical care in TGD youth. However, there are significant gaps in knowledge and challenges to such care. Long-term safety and efficacy studies are needed to optimize medical care for TGD youth.

Abstract
It has been a quarter of a century since Dutch clinicians proposed puberty suppression as an intervention for "juvenile transsexuals," which became the international standard for treating gender dysphoria. This paper reviews the history of this intervention and scrutinizes the evidence adduced to support it. The intervention was justified by claims that it was reversible and that it was a tool for diagnosis, but these claims are increasingly implausible. The main evidence for the Dutch protocol came from a longitudinal study of 70 adolescents who had been subjected to puberty suppression followed by cross-sex hormones and surgery. Their outcomes shortly after surgery appeared positive, except for the one patient who died, but these findings rested on a small number of observations and incommensurable measures of gender dysphoria. A replication study conducted in Britain found no improvement. While some effects of puberty suppression have been carefully studied, such as on bone density, others have been ignored, like on sexual functioning.

Abstract
As the transgender and gender diverse (TGD) population ages, more transfeminine and transmasculine individuals present to clinic to initiate or continue their gender-affirming care at older ages. Currently available guidelines on gender-affirming care are excellent resources for the provision of gender-affirming hormone therapy (GAHT), primary care, surgery, and mental health care but are limited in their scope as to whether recommendations require tailoring to older TGD adults. Data that inform guideline-recommended management considerations, while informative and increasingly evidence-based, mainly come from studies of younger TGD populations. Whether results from these studies, and therefore recommendations, can or should be extrapolated to aging TGD adults remains to be determined. In this perspective review, we acknowledge the lack of data in older TGD adults and discuss considerations for evaluating cardiovascular disease, hormone-sensitive cancers, bone health and cognitive health, gender-affirming surgery, and mental health in the older TGD population on GAHT.

Abstract
Transgender and gender non-conforming (TGNC) individuals face numerous barriers to healthcare, which contribute to many health disparities. TGNC persons may choose gender-affirming therapies with surgery and/or hormone replacement therapy (HRT) to manage gender incongruence. Despite the expanding use of HRT, the long-term outcomes on bone health and metabolism, are still relatively unknown in the TGNC population. In 2019, the International Society of Clinical Densitometry (ISCD) released an official position statement on the appropriate use of dual energy x-ray absorptiometry (DXA) to measure bone density in the TGNC population. In this study, we reviewed which "sex" is currently utilized among providers when performing DXA scans to calculate T- and Z-scores for TGNC persons and how this compares to the positions published by the ISCD. A retrospective analysis was performed utilizing HERON queries and subsequent chart review. HERON is a type of Informatics for Integrating Biology and the Bedside software that was utilized to find sets of patients of interest from electronic medical record data while preserving patient privacy through a query interface tool. Project specific sets including patient demographics, medications, gonadectomy, and DXA scan information was created in HERON to make this highly detailed data of specific patients available to the investigators on the platform, as reviewed and retrieved by the Institutional Review Board. The qualitative DXA data obtained from chart review was determined as "correct" or "incorrect" based on positions provided from the ISCD. 10 DXA scans that met inclusion criteria were obtained between 9 TGNC patients. In total, 18 T-scores and Z-scores of the 10 DXAs were reviewed and scored. Based on ISCD positions, 67% of the T-score and Z-scores were calculated incorrectly; using the erroneous "sex" based standard to compare scores. Like DXA scans, many current healthcare standards and protocols are based on a patient's sex or gender, which may cause confusion amongst healthcare personnel who have not received proper training regarding the TGNC population. In this study, 67% of T-scores and Z-scores were calculated incorrectly based on ISCD recommendations. An additional prospective research design is required to determine the consequences of incorrectly calculated DXA scans for TGNC patients. Furthermore, future research is needed to determine HRT's effects on bone mineral density in the TGNC population in the United States.

Abstract
Background: Transgender healthcare is a rapidly evolving interdisciplinary field. In the last decade, there has been an unprecedented increase in the number and visibility of transgender and gender diverse (TGD) people seeking support and gender-affirming medical treatment in parallel with a significant rise in the scientific literature in this area. The World Professional Association for Transgender Health (WPATH) is an international, multidisciplinary, professional association whose mission is to promote evidence-based care, education, research, public policy, and respect in transgender health. One of the main functions of WPATH is to promote the highest standards of health care for TGD people through the Standards of Care (SOC). The SOC was initially developed in 1979 and the last version (SOC-7) was published in 2012. In view of the increasing scientific evidence, WPATH commissioned a new version of the Standards of Care, the SOC-8. Aim: The overall goal of SOC-8 is to provide health care professionals (HCPs) with clinical guidance to assist TGD people in accessing safe and effective pathways to achieving lasting personal comfort with their gendered selves with the aim of optimizing their overall physical health, psychological well-being, and self-fulfillment. Methods: The SOC-8 is based on the best available science and expert professional consensus in transgender health. International professionals and stakeholders were selected to serve on the SOC-8 committee. Recommendation statements were developed based on data derived from independent systematic literature reviews, where available, background reviews and expert opinions. Grading of recommendations was based on the available evidence supporting interventions, a discussion of risks and harms, as well as the feasibility and acceptability within different contexts and country settings. Results: A total of 18 chapters were developed as part of the SOC-8. They contain recommendations for health care professionals who provide care and treatment for TGD people. Each of the recommendations is followed by explanatory text with relevant references. General areas related to transgender health are covered in the chapters Terminology, Global Applicability, Population Estimates, and Education. The chapters developed for the diverse population of TGD people include Assessment of Adults, Adolescents, Children, Nonbinary, Eunuchs, and Intersex Individuals, and people living in Institutional Environments. Finally, the chapters related to gender-affirming treatment are Hormone Therapy, Surgery and Postoperative Care, Voice and Communication, Primary Care, Reproductive Health, Sexual Health, and Mental Health. Conclusions: The SOC-8 guidelines are intended to be flexible to meet the diverse health care needs of TGD people globally. While adaptable, they offer standards for promoting optimal health care and guidance for the treatment of people experiencing gender incongruence. As in all previous versions of the SOC, the criteria set forth in this document for gender-affirming medical interventions are clinical guidelines; individual health care professionals and programs may modify these in consultation with the TGD person.

Bone density and bone marrow composition in transgender girls prior to pubertal blockade: A case series. Bone 2022; 162:116454. [PMID: 35667601 PMCID: PMC9792193 DOI: 10.1016/j.bone.2022.116454] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 11/23/2021] [Revised: 04/12/2022] [Accepted: 05/31/2022] [Indexed: 11/21/2022]
Abstract
PURPOSE To determine bone mineral density (BMD) of transgender girls before pubertal blockade, and correlate with lifestyle and clinical variables. METHODS Six transfemale peri-pubertal girls had knee magnetic resonance imaging (MRI) with T1-weighted images and single-voxel proton magnetic resonance spectroscopy (MRS). BMD measurements were obtained via dual-energy X-ray absorptiometry. Questionnaires about physical activity, diet, and the Eating Attitudes Test (EAT-26) were completed. The T2 relaxation rate of water (R2 = 1/T2 in s -1) was correlated with scores on surveys. RESULTS Three participants (50 %) had a low bone mineral density for age based on total body less head Z-score less than -2; two participants (33 %) had a low BMD for age at lumbar spine. All had EAT-26 scores below threshold for clinical concern. All participants self-reported regular exercise. Bone marrow MR variables (T1, fat fraction, unsaturation index and R2 of water) were not correlated with DXA measures. CONCLUSIONS Participants had low BMD on beginning pubertal blockade. Clinicians should consider monitoring BMD among youth AMAB, a group at potential risk for poor bone health.

Abstract
Purpose We aimed to study determinants of bone health in transgender youth in anticipation of or shortly after initiating puberty suppression and/or gender-affirming hormone therapy. Methods This was a retrospective review of records of transgender adolescents in our institution between June 2014 and June 2019. Dual energy X-ray absorptiometry was used to assess bone mineral density (BMD). Baseline characteristics were collected and included in a multilinear regression model to assess determinants of lumbar spine (LS) BMD Z-scores adjusted for age and height and accounting for race. Welch's t-test was used to compare characteristics across genders. Results One hundred nineteen patient records were analyzed. Forty-six patients (38.7%) were assigned male at birth (AMAB) and 73 patients (61.3%) were assigned female at birth (AFAB). Mean (±standard deviation [SD]) age (years) was 14.7±2.6 for AMAB and 15.0±2.2 for AFAB. The adjusted LS BMD Z-score was lower in the AMAB population with a mean (+SD) of -0.605±1.42 compared with 0.043±1.09 in AFAB (p=0.010). In a multivariate model, AMAB gender, vitamin D deficiency, and lower body mass index (BMI) z-scores were determinants of lower LS BMD Z-scores (R 2=0.206). Age, race, ethnicity, insurance status, and Tanner stage were not determinants of BMD. However, post hoc analysis did show that pubertal status modified the results. Conclusion AMAB transgender adolescents have lower BMD compared with AFAB patients, before or shortly after starting puberty suppression and/or gender-affirming hormone therapy. Lower BMI and vitamin D deficiency were determinants of lower BMD. Further studies are needed to explore etiology for bone health discrepancy in this population.

Abstract
This review discusses the changes in bone mass, structure, and metabolism that occur upon gender-affirming hormonal treatment (GAHT) in transgender adults and adolescents, as well as their clinical relevance. In general, available evidence shows that GAHT in transgender adults is not associated with major bone loss. In transgender adolescents, pubertal suppression with gonadotropin-releasing hormone agonist monotherapy impairs bone development, but at least partial recovery is observed after GAHT initiation. Nevertheless, a research gap remains concerning fracture risk and determinants of bone strength other than bone mineral density. Attention for bone health is warranted especially in adult as well as adolescent trans women, given the relatively high prevalence of low bone mass both before the start of treatment and after long-term GAHT in this population. Strategies to optimize bone health include monitoring of treatment compliance and ensuring adequate exposure to administered sex steroids, in addition to general bone health measures such as adequate physical activity, adequate vitamin D and calcium intake, and a healthy lifestyle. When risk factors for osteoporosis exist the threshold to perform DXA should be low, and treatment decisions should be based on the same guidelines as the general population.

Abstract
Internationally, increasing numbers of children and adolescents with gender dysphoria are presenting for care. In response, gender-affirming therapeutic interventions that seek to align bodily characteristics with an individual's gender identity are more commonly being used. Depending on a young person's circumstances and goals, hormonal interventions may aim to achieve full pubertal suppression, modulation of endogenous pubertal sex hormone effects, and/or development of secondary sex characteristics congruent with their affirmed gender. This is a relatively novel therapeutic area and, although short-term outcomes are encouraging, longer term data from prospective longitudinal adolescent cohorts are still lacking, which may create clinical and ethical decision-making challenges. Here, we review current treatment options, reported outcomes, and clinical challenges in the pharmacological management of trans and gender-diverse adolescents.

Abstract
Bone health in transmen and transwomen is an important issue that needs to be evaluated by clinicians. Prior to gender-affirming hormone treatment (GAHT), transwomen have lower bone mineral density (BMD) and a higher prevalence of osteopenia than cismen probably related to external factors, such as hypovitaminosis D and less physical activities. Gonadotropin-releasing hormone (GnRH) analogues in transgender youth may cause bone loss; however, the addition of GAHT restores or at least improves BMD in both transboys and transgirls. The maintenance or increase in BMD shown in short-term longitudinal studies emphasizes that GAHT does not have a negative effect on BMD in adult transwomen and transmen. Gonadectomy is not a risk factor if GAHT is taken correctly. The prevalence of fractures in the transgender population seems to be the same as in the general population but more studies are required on this aspect. To evaluate the risk of osteoporosis, it is mandatory to define the most appropriate reference group not only taking into consideration the medical aspects but also in respect of the selected gender identity of each person.

Bone Health in School Age Children: Effects of Nutritional Intake on Outcomes. Front Nutr 2021; 8:773425.

Abstract
The maximum rate of bone mass accumulation is during early adolescence. As such, a focus on optimizing mineral nutrition in school age children, defined here as approximately 5 to 15 years of age, is crucial to minimize the risk of bone loss that occurs later in life leading to osteoporosis and fractures. Optimizing bone mass in this age group requires attention to an overall healthy diet including adequate calcium, phosphorus, magnesium, and vitamin D. Special concerns may exist related to children who follow a restricted diet such as a vegan diet, those with intolerance or allergies to dairy, and those with chronic health conditions including young adolescents with eating disorders. Public policy messages should focus on positive aspects of bone health nutrition in this age group and avoid overly specific statements about the exact amounts of foods needed for healthy bones. In this regard, dietary recommendations for minerals vary between North America and Europe and these are higher than the values that may be necessary in other parts of the world. The management of many children with chronic illnesses includes the use of medications that may affect their bone mineral metabolism. Routine lab testing for bone mineral metabolism including the serum 25-hydroxyvitamin D level is not indicated, but is valuable for at-risk children, especially those with chronic illnesses.

Abstract
An increasing number of transgender and gender-diverse (TGD) youth (early pubertal through to late adolescent, typically 9-10 through to 18 years of age) are seeking medical services to bring their physical sex characteristics into alignment with their gender identity - their inner sense of self as male or female or somewhere on the gender spectrum. Compelling research has demonstrated the clear mental health - even life-saving - benefits of gender-affirming care, but current clinical practice guidelines and standards of care are based on only several short-term and a few medium-term outcomes studies complemented by expert opinion. Nevertheless, although the relative paucity of outcomes data raises concerns, the stance of not intervening until more is known is not a neutral option, and large observational studies evaluating current models of care are necessary and are now underway. This Review highlights key advances in our understanding of transgender and gender-diverse youth, the challenges of providing gender-affirming care, gaps in knowledge and priorities for research.

Abstract
Nonbinary and genderqueer youth represent well over a one-third of transgender youth. Historically, transgender health care has been based on the gender binary, and as a result, many nonbinary people have chosen to forego care or withhold their authentic needs or goals when accessing care. This article presents a paradigm shift in gender care, which addresses discrimination and stigma and outlines components of supportive and affirming care to gender expansive youth. Nonbinary youth are best served when providers use gender-affirming language and focus on embodiment goals. Medical interventions may include pubertal suppression, hormones, and surgeries, which are best reviewed by individual physical effects rather than with "masculinizing" or "feminizing" terminology. Individualized goals may be supported by estrogen, testosterone, or a combination of both. Providers should be prepared to facilitate supportive conversations, difficult decisions, and balancing of priorities with nonbinary patients and their families. [Pediatr Ann. 2021;50(9):e384-e390.].

Abstract
Context Transgender youth may initiate GnRH agonists (GnRHa) to suppress puberty, a critical period for bone-mass accrual. Low bone mineral density (BMD) has been reported in late-pubertal transgender girls before gender-affirming therapy, but little is known about BMD in early-pubertal transgender youth. Objective To describe BMD in early-pubertal transgender youth. Design Cross-sectional analysis of the prospective, observational, longitudinal Trans Youth Care Study cohort. Setting Four multidisciplinary academic pediatric gender centers in the United States. Participants Early-pubertal transgender youth initiating GnRHa. Main Outcome Measures Areal and volumetric BMD Z-scores. Results Designated males at birth (DMAB) had below-average BMD Z-scores when compared with male reference standards, and designated females at birth (DFAB) had below-average BMD Z-scores when compared with female reference standards except at hip sites. At least 1 BMD Z-score was < -2 in 30% of DMAB and 13% of DFAB. Youth with low BMD scored lower on the Physical Activity Questionnaire for Older Children than youth with normal BMD, 2.32 ± 0.71 vs. 2.76 ± 0.61 (P = 0.01). There were no significant deficiencies in vitamin D, but dietary calcium intake was suboptimal in all youth. Conclusions In early-pubertal transgender youth, BMD was lower than reference standards for sex designated at birth. This lower BMD may be explained, in part, by suboptimal calcium intake and decreased physical activity–potential targets for intervention. Our results suggest a potential need for assessment of BMD in prepubertal gender-diverse youth and continued monitoring of BMD throughout the pubertal period of gender-affirming therapy.
