RESUMEN

BACKGROUND: Limited prospective outcome data exist regarding transgender and nonbinary youth receiving gender-affirming hormones (GAH; testosterone or estradiol). METHODS: We characterized the longitudinal course of psychosocial functioning during the 2 years after GAH initiation in a prospective cohort of transgender and nonbinary youth in the United States. Participants were enrolled in a four-site prospective, observational study of physical and psychosocial outcomes. Participants completed the Transgender Congruence Scale, the Beck Depression Inventory-II, the Revised Children's Manifest Anxiety Scale (Second Edition), and the Positive Affect and Life Satisfaction measures from the NIH (National Institutes of Health) Toolbox Emotion Battery at baseline and at 6, 12, 18, and 24 months after GAH initiation. We used latent growth curve modeling to examine individual trajectories of appearance congruence, depression, anxiety, positive affect, and life satisfaction over a period of 2 years. We also examined how initial levels of and rates of change in appearance congruence correlated with those of each psychosocial outcome. RESULTS: A total of 315 transgender and nonbinary participants 12 to 20 years of age (mean [±SD], 16±1.9) were enrolled in the study. A total of 190 participants (60.3%) were transmasculine (i.e., persons designated female at birth who identify along the masculine spectrum), 185 (58.7%) were non-Latinx or non-Latine White, and 25 (7.9%) had received previous pubertal suppression treatment. During the study period, appearance congruence, positive affect, and life satisfaction increased, and depression and anxiety symptoms decreased. Increases in appearance congruence were associated with concurrent increases in positive affect and life satisfaction and decreases in depression and anxiety symptoms. The most common adverse event was suicidal ideation (in 11 participants [3.5%]); death by suicide occurred in 2 participants. CONCLUSIONS: In this 2-year study involving transgender and nonbinary youth, GAH improved appearance congruence and psychosocial functioning.

RESUMEN

BACKGROUND: Equations for estimated glomerular filtration rate (eGFR) based on serum creatinine include terms for sex/gender. For transgender and gender-diverse (TGD) youth, gender-affirming hormone (GAH) treatment may affect serum creatinine and in turn eGFR. METHODS: TGD youth were recruited for this prospective, longitudinal, observational study prior to starting GAH treatment. Data collected as part of routine clinical care were abstracted from the medical record. RESULTS: For participants designated male at birth (DMAB, N = 92), serum creatinine decreased within 6 months of estradiol treatment (mean ± SD 0.83 ± 0.12 mg/dL to 0.76 ± 0.12 mg/dL, p < 0.001); for participants designated female at birth (DFAB, n = 194), serum creatinine increased within 6 months of testosterone treatment (0.68 ± 0.10 mg/dL to 0.79 ± 0.11 mg/dL, p < 0.001). Participants DFAB treated with testosterone had serum creatinine similar to that of participants DMAB at baseline, whereas even after estradiol treatment, serum creatinine in participants DMAB remained higher than that of participants DFAB at baseline. Compared to reference groups drawn from the National Health and Nutritional Examination Survey, serum creatinine after 12 months of GAH was more similar when compared by gender identity than by designated sex. CONCLUSION: GAH treatment leads to changes in serum creatinine within 6 months of treatment. Clinicians should consider a patient's hormonal exposure when estimating kidney function via eGFR and use other methods to estimate GFR if eGFR based on serum creatinine is concerning.

RESUMEN

Mobile health interventions to promote adherence to antiretroviral therapy among adolescents and young adults living with HIV represent a promising strategy. This pilot study (N = 37) evaluated the psychosocial impacts of an efficacious adherence intervention, cell phone support (CPS). Participants receiving CPS reported significant decreases in perceived stress, depression, and illicit substance use, and increases in self-efficacy during at least one study assessment period, in comparison to participants receiving usual care. Future research using a larger sample should test for mediators of treatment efficacy to further characterize how cell phone interventions impact adherence.

RESUMEN

Oral pre-exposure prophylaxis (PrEP) in the prevention of human immunodeficiency virus (HIV) infection is highly effective, yet the majority of sexually active adolescents and young adults (AYAs) at highest risk for HIV infection, particularly AYA males who have sex with males, have not been prescribed this medication. Provider hesitancy in prescribing PrEP to at-risk AYA patients is often associated with concerns about patient nonadherence and its effect on inducing HIV medication resistance. This case report has two aims. First, to outline the clinical course for an AYA patient prescribed PrEP for 3 months and then found to have HIV with an M184V resistance mutation and subsequently started on HIV treatment. And second, to illustrate how the benefits of PrEP initiation outweigh its risks by presenting clinical data on resistance patterns to PrEP medications. The patient eventually achieved viral suppression within 5 months of starting HIV treatment which has been sustained up to 2 years. This case illustrates that M184V resistance mutations, although rarely associated with PrEP, are unlikely to impact options for HIV treatment. Providers should recommend and prescribe oral PrEP to AYA patients at risk for HIV infection without concern for nonadherence leading to HIV medication resistance.

RESUMEN

Background: Despite multiple rigorous observational studies documenting the association between positive mental health outcomes and access to puberty blockers, hormone therapy, and transition-related surgeries among adolescents, some jurisdictions have banned or are attempting to ban gender-affirming medical interventions for minors due to an absence of randomized-controlled trials (RCTs) proving their mental health benefits. Methods: This article critically reviews whether RCTs are methodologically appropriate for studying the association between adolescent gender-affirming care and mental health outcomes. Results: The scientific value of RCTs is severely impeded when studying the impact of gender-affirming care on the mental health of trans adolescent. Gender-affirming interventions have physiologically evident effects and are highly desired by participants, giving rise to concerns over adherence, drop-out, response bias, and generalizability. Complementary and well-designed observational studies can instead be used to ground reliable recommendations for clinical practice and policymaking in adolescent trans healthcare, without the need for RCTs. Conclusion: The lack of RCTs on the mental health impacts of gender-affirming care for trans adolescents does not entail that gender-affirming interventions are based on insufficient evidence. Given the methodological limitations of RCTs, complementary and well-designed observational studies offer more reliable scientific evidence than RCTs and should be considered of sufficient quality to guide clinical practice and policymaking.

RESUMEN

OBJECTIVES: Guidelines for monitoring of medications frequently used in the gender-affirming care of transgender and gender-diverse (TGD) adolescents are based on studies in adults or other medical conditions. In this study, we aimed to investigate commonly screened laboratory measurements in TGD adolescents receiving gender-affirming hormone therapy (GAHT). METHODS: TGD adolescents were recruited from 4 study sites in the United States before beginning GAHT. Hemoglobin, hematocrit, hemoglobin A1c, alanine transaminase, aspartate aminotransferase, prolactin, and potassium were abstracted from the medical record at baseline and at 6, 12, and 24 months after starting GAHT. RESULTS: Two-hundred and ninety-three participants (68% designated female at birth) with no previous history of gonadotropin-releasing hormone analog use were included in the analysis. Hemoglobin and hematocrit decreased in adolescents prescribed estradiol (-1.4 mg/dL and -3.6%, respectively) and increased in adolescents prescribed testosterone (+1.0 mg/dL and +3.9%) by 6 months after GAHT initiation. Thirteen (6.5%) participants prescribed testosterone had hematocrit > 50% during GAHT. There were no differences in hemoglobin A1c, alanine transaminase, or aspartate aminotransferase. There was a small increase in prolactin after 6 months of estradiol therapy in transfeminine adolescents. Hyperkalemia in transfeminine adolescents taking spironolactone was infrequent and transient if present. CONCLUSIONS: Abnormal laboratory results are rare in TGD adolescents prescribed GAHT and, if present, occur within 6 months of GAHT initiation. Future guidelines may not require routine screening of these laboratory parameters beyond 6 months of GAHT in otherwise healthy TGD adolescents.

RESUMEN

BACKGROUND: Prepubertal transgender, nonbinary, and gender-diverse (TGD) children (ie, those asserting gender identity, expressing gender-role behavior outside of culturally defined norms for their sex registered at birth, or both) are presenting in greater numbers to pediatric gender clinics across the United States and abroad. A large subset of TGD children experiences gender dysphoria, that is, distress that arises from the incongruence between gender identity and sex registered at birth. A lack of consensus exists regarding care for prepubertal TGD children due, in part, to a dearth of empirical research on longitudinal developmental trajectories of gender identity, role behavior, and gender dysphoria (when present). OBJECTIVE: The objective of this National Institutes of Health-funded study is to provide evidence to inform clinical care for prepubertal TGD children by establishing a US longitudinal cohort (N=248) of prepubertal TGD children and their caregivers that is followed prospectively at 6-month intervals across 18 months. METHODS: At each timepoint, clinical and behavioral data are collected via web-based visit from child and caregiver reporters. Latent class analysis, among other methods, is used to identify subgroups and longitudinally characterize the gender identity and gender-role behavior of TGD children. These models will define longitudinal patterns of gender identity stability and characterize the relationship between TGD classes and mental and behavioral health outcomes, including the moderating role of social gender transition (when present), on these associations. RESULTS: Baseline data collection (N=248) is complete, and the identification of TGD subgroups based on gender identity and expression using latent class analysis is anticipated in 2024. The completion of all 4 waves of data collection is anticipated in July 2024, coinciding with the start of a no-cost study extension period. We anticipate longitudinal analyses to be completed by winter 2024. CONCLUSIONS: Through a longitudinal observational design, this research involving prepubertal TGD children and their caregivers aims to provide empirical knowledge on gender development in a US sample of TGD children, their mental health symptomology and functioning over time, and how family initiated social gender transition may predict or alleviate mental health symptoms or diagnoses. The research findings have promise for clinicians and families aiming to ensure the best developmental outcome for these children as they develop into adolescents.

RESUMEN

PURPOSE: Prior studies have identified a significant relationship between internalized transphobia and poor mental health among transgender and gender-diverse (TGD) adults; however, this relationship has not been extensively examined among youth. Further, little research has sought to explore protective factors, such as identity pride, and their influence on this relationship. We examined the association between internalized transphobia and depression and anxiety symptoms among TGD youth and explored the moderating role of gender identity pride on these associations. METHODS: Participants were 315 TGD youth ages 12-20 years (mean = 16; standard deviation = 1.89) seeking gender-affirming hormone treatment at one of four major pediatric hospitals across the United States. At the time of enrollment, participants were naïve to gender-affirming hormone treatment. Participants self-reported mental health, internalized transphobia, and identity pride. Multiple regression models were used with depression and anxiety symptoms as outcomes and age, designated sex at birth, and perceived parental support included as covariates. RESULTS: Greater internalized transphobia was associated with greater depressive symptoms, and gender identity pride moderated this relationship, such that greater gender identity pride was associated with fewer depressive symptoms. Greater internalized transphobia was significantly associated with greater anxiety symptoms; no moderation effect was observed for this relationship. DISCUSSION: Gender identity pride influenced mental health symptoms for youth experiencing internalized transphobia and represents a potential key protective factor. These results support efforts to further develop, test, and implement clinical inventions to bolster identity pride for TGD youth.

RESUMEN

PURPOSE: To compare baseline mental health symptoms and gender affirmation between Black/Latine versus White transgender/nonbinary youth (BLTY vs. WTY) and examine relationships between gender affirmation and mental health symptoms, and whether associations differed by race/ethnicity subgroup. METHODS: Baseline data were analyzed from the gender-affirming hormone cohort of the Trans Youth Care United States Study-a 4-clinic site, observational study. Mental health symptoms assessed included depression, suicidality, and anxiety. Gender affirmation measures included the parental acceptance subscale from the perceived Parental Attitudes of Gender Expansiveness Scale-Youth Report; non-affirmation, internalized transphobia, and community connectedness subscales from the Gender Minority Stress and Resilience Measure-Adolescent; and self-reported living full time in affirmed gender. Fisher exact tests and independent sample t tests compared mental health symptoms and gender affirmation between subgroups. Logistic regression analyses evaluated associations between gender affirmation and mental health symptoms. Interaction analyses assessed differences in associations between subgroups. RESULTS: The sample (mean age 16 years, range 12-20 years) included 92 BLTY (35%) and 170 WTY (65%). Subgroups had comparable prevalence of depression and anxiety symptoms. WTY had higher prevalence of lifetime suicidality (73% vs. 59%; p = .02). There were no differences in gender affirmation. Among the whole sample, higher parental acceptance decreased odds of depression symptoms. Not living in affirmed gender increased odds of depression symptoms. Higher non-affirmation and internalized transphobia increased odds of depression and anxiety symptoms and suicidality. Associations did not vary by subgroup. DISCUSSION: BLTY and WTY had comparable mental health symptoms. For both subgroups, gender affirmation decreased odds of those symptoms.

RESUMEN

Client-centered practice requires therapists to actively seek the perspectives of children and families. Several assessment tools are available to facilitate this process. However, when evaluating motor skill performance, therapists typically concentrate on performance-based assessment. To improve understanding of the information provided by the different approaches, the study investigated correlations between performance-based, child-report, and parent-report measures of children's motor skill performance. A sample of convenience of 38 children 8-12 years of age with no history of motor or intellectual impairments and their parents was recruited from Victoria, Australia. Scores for the Bruininks-Oseretsky Test of Motor Proficiency (performance-based, administered by a therapist), Physical Self-Description Questionnaire (child report), and Movement Assessment Battery for Children Checklist (parent report) were analyzed using Spearman's rho correlation. Several significant moderate-to-large correlations were found between scores for parent-report and scores for performance-based assessments, while few significant correlations were found between scores for child report and scores for the other two measures. The results suggest that children offer a unique perspective which should be integrated with other sources of information to gain a more holistic perspective of their motor skill performance.

RESUMEN

PURPOSE: Transgender/gender-diverse (TGD) youth are treated with gonadotropin-releasing hormone agonists (GnRHas) to halt endogenous puberty and prevent the development of secondary sex characteristics discordant with their gender identity. This treatment may have significant impact on growth and height velocity (HV). METHODS: Participants were recruited prior to GnRHa initiation from four gender specialty clinics in the U.S. Anthropometric, laboratory, and Tanner-stage data were abstracted from medical records. RESULTS: Fifty-five TGD youth (47% designated male at birth) with a mean ± standard deviation age of 11.5 ± 1.2 years were included in the analysis. HV in the first year of GnRHa use was median (interquartile range) 5.1 (3.7-5.6) cm/year. Later Tanner stage at GnRHa initiation was associated with lower HV: 5.3 (4.4-5.6) cm/year for Tanner stage II, 4.4 (3.3-6.0) cm/year for Tanner stage III, and 1.6 (1.5-2.9) cm/year for Tanner stage IV (p = .001). When controlled for age, there was not a significant difference in mean HV between TGD youth and prepubertal youth; however, when stratified by Tanner stage individuals starting GnRHa at Tanner stage IV had an HV below that of prepubertal youth, 1.6 (1.5-2.9) versus 6.1 (4.3-6.5) cm/year, p = .006. CONCLUSIONS: Overall, TGD youth treated with GnRHa have HV similar to that of prepubertal children, but TGD youth who start GnRHa later in puberty have an HV below the prepubertal range. Ongoing follow-up of this cohort will determine the impact of GnRHa treatment on adult height.

RESUMEN

In brain tissue of three harbor seals of the German North Sea coast, high virus loads of highly pathogenic avian influenza virus (HPAIV) H5N8 were detected. Identification of different virus variants indicates high exposure to HPAIV circulating in wild birds, but there is no evidence for H5 specific antibodies in healthy seals. Replication of avian viruses in seals may allow HPAIV to acquire mutations needed to adapt to mammalian hosts as shown by PB2 627K variants detected in these cases.

RESUMEN

Purpose: Development of incongruent secondary sex characteristics in transgender youth can intensify or trigger the onset of gender dysphoria. Guidelines from professional organizations recommend gonadotropin-releasing hormone agonists, including histrelin implants (Vantas and SupprelinLA) to suppress endogenous puberty. Although Vantas does not have a pediatric indication, it is anecdotally being used in pediatric gender centers throughout the United States because of its substantially lower cost. This retrospective study aimed to determine if both implants were effective in suppressing the hypothalamic-pituitary-gonadal axis in early-to-mid pubertal youth with gender dysphoria. Methods: Youth with gender dysphoria receiving care at the Center for Transyouth Health and Development at Children's Hospital Los Angeles (CHLA) or participants from an ongoing observational trial with a histrelin implant placed for pubertal suppression at Tanner stage 2 or 3 were included. Sex steroid (testosterone or estradiol) and gonadotropin measurements at baseline (T0) and then 2 to 12 months following implant placement (T1) were abstracted from medical records. Results: Of the 66 eligible participants, 52% were designated female at birth. Most participants were white (60.6%). Twenty participants (30.3%) had a Vantas implant and 46 (69.7%) had a SupprelinLA implant. Mean age of insertion was 11.3 years. Gonadotropin and sex steroid levels were significantly decreased at T1 (2-12 months after insertion of implant), with no differences between implants. Conclusion: These results indicate that both implants are effective in suppressing puberty in early-to-mid pubertal youth with gender dysphoria. These data may inform decisions about insurance coverage of Supprelin and/or Vantas for youth with gender dysphoria.

RESUMEN

PURPOSE: There is a sparsity of information on chest binding practices among transmasculine and gender diverse people regardless of age and even less information pertaining to adolescents and young adults (AYA). The purpose of this study was to understand binding trends in AYA and to recognize how chest binding impacts chest dysphoria and life satisfaction. METHODS: Data were collected from eligible participants via a national online survey. In this national, cross-sectional study, 684 surveys from AYA aged 13-24 years compared those who bind and those who do not bind. RESULTS: Most participants reported learning to bind online and were not connected to any type of gender care or community center. Participants in the binding cohort reported less "misgendering" than the nonbinding cohort, and there was a significant correlation between increased chest dysphoria and lower scores on life satisfaction. CONCLUSIONS: This study provides insight into how AYA obtain information about binding and how binding impacts their life. It also indicates that transmasculine and gender diverse AYA will continue to bind their chest to benefit from the protective factors experienced with chest binding. This study also highlights the importance of improved education for medical providers as well as parents/guardians regarding binding to support those who experience chest dysphoria or discomfort.

RESUMEN

PURPOSE: This study aimed to characterize two developmental cohorts of transgender and nonbinary youth enrolled in the Trans Youth Care Network Study and describe their gender identity-related milestones and baseline mental health and psychosocial functioning. METHODS: Trans Youth Care participants were recruited from four pediatric academic medical centers in the U.S. before initiating medical treatment for gender dysphoria either with gonadotropin-releasing hormone agonists (GnRHa) or gender-affirming hormones (GAH). GnRHa cohort data were collected from youth and a parent; GAH cohort data were collected from youth only. RESULTS: A total of 95 youth were enrolled in the GnRHa cohort. Mean age was 11.22 years (standard deviation = 1.46), and the majority were white (52.6%) and designated male at birth (51.6%). Elevated depression symptoms were endorsed by 28.6% of GnRHa cohort youth, and 22.1% endorsed clinically significant anxiety. Approximately one fourth (23.6%) endorsed lifetime suicidal ideation, with 7.9% reporting a past suicide attempt. A total of 316 youth were enrolled in the GAH cohort. The mean age was 16.0 years (standard deviation = 1.88), and the majority were white (62%) and designated female at birth (64.9%). Elevated depression symptoms were endorsed by 51.3% of the GAH cohort, and 57.3% endorsed clinically significant anxiety. Two-thirds (66.6%) endorsed lifetime suicidal ideation, with 24.6% reporting a past suicide attempt. Life satisfaction was lower among both cohorts compared with population-based norms. CONCLUSIONS: GnRHa cohort youth appear to be functioning better from a psychosocial standpoint than GAH cohort youth, pointing to possible benefits of accessing gender-affirming treatment earlier in life.

RESUMEN

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 ±â€…0.71 vs. 2.76 ±â€…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.

RESUMEN

PURPOSE: The purpose of this study was to describe baseline physical and laboratory characteristics of participants in the largest prospective study of transgender and gender-diverse (TGD) youth in the United States. METHODS: Participants were recruited from four clinics which specialize in the care of TGD youth before starting either GnRH analogs for pubertal suppression or gender-affirming hormone treatment. Anthropometric and laboratory measurements were abstracted from the medical chart. Baseline characteristics including height, weight, body mass index, blood pressure, and laboratory measurements were compared with those of age-matched National Health and Nutritional Examination Survey comparison group. RESULTS: Seventy-eight TGD youth with a median age of 11 years (range 8-14 years) were recruited before pubertal suppression, of whom 41 (53%) were designated male at birth, and 296 participants with a median age of 16 years (range 12-20 years) were recruited before beginning gender-affirming hormones, of whom 99 (33%) were designated male at birth. The mean high-density lipoprotein cholesterol was lower in the study participants when compared with that of National Health and Nutritional Examination Survey participants (50.6 ± 12.3 mg/dL vs. 53.3 ± 13.3 mg/dL, p = .001). Otherwise, the study cohorts were similar in terms of body mass index, proportion of overweight and obesity, blood pressure, and baseline laboratory variables. CONCLUSIONS: Before starting gender-affirming treatment, TGD youth are physiologically similar to the general population of children and adolescents in the United States, with the exception of slightly lower high-density lipoprotein cholesterol. Evaluation of this cohort over time will define the physiological effects of pubertal blockade and gender-affirming hormone treatment.

RESUMEN

Many transgender and gender-diverse people have a gender identity that does not conform to the binary categories of male or female; they have a nonbinary gender. Some nonbinary individuals are most comfortable with an androgynous gender expression. For those who have not yet fully progressed through puberty, puberty suppression with gonadotrophin-releasing hormone agonists can support an androgynous appearance. Although such treatment is shown to ameliorate the gender dysphoria and serious mental health issues commonly seen in transgender and gender-diverse young people, long-term use of puberty-suppressing medications carries physical health risks and raises various ethical dilemmas. In this Ethics Rounds, we analyze a case that raised issues about prolonged pubertal suppression for a patient with a nonbinary gender.
