Assessing and Addressing the Risk of Venous Thromboembolism Across the Spectrum of Gender Affirming Care: A Review.

OBJECTIVE: Accumulating evidence demonstrates that gender affirming hormone therapy (GAHT) improves mental health outcomes in transgender persons. Data specific to the risks associated with GAHT for transgender persons continue to emerge, allowing for improvements in understanding, predicting, and mitigating adverse outcomes while informing discussion about desired effects. Of particular concern is the risk of venous thromboembolism (VTE) in the context of both longitudinal GAHT and the perioperative setting. Combining what is known about the risk of VTE in cisgender individuals on hormone therapy (HT) with the evidence for transgender persons receiving HT allows for an informed approach to assess underlying risk and improve care in the transgender community. OBSERVATIONS: Hormone formulation, dosing, route, and duration of therapy can impact thromboembolic risk, with transdermal estrogen formulations having the lowest risk. There are no existing risk scores for VTE that consider HT as a possible risk factor. Risk assessment for recurrent VTE and bleeding tendencies using current scores may be helpful when assessing individual risk. Gender affirming surgeries present unique perioperative concerns, and certain procedures include a high likelihood that patients will be on exogenous estrogens at the time of surgery, potentially increasing thromboembolic risk. CONCLUSIONS AND RELEVANCE: Withholding GAHT due to potential adverse events may cause negative impacts for individual patients. Providers should be knowledgeable about the management of HT in transgender individuals of all ages, as well as in the perioperative setting, to avoid periods in which transgender individuals are off GAHT. Treatment decisions for both anticoagulation and HT should be individualized and tailored to patients' overall goals and desired outcomes, given that the physical and mental health benefits of gender affirming care may outweigh the risk of VTE.

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.

Behavioral Health Diagnoses in Youth with Gender Dysphoria Compared with Controls: A PEDSnet Study.

OBJECTIVE: To assess the odds of a psychiatric or neurodevelopmental diagnosis among youth with a diagnosis of gender dysphoria compared with matched controls in a large electronic health record dataset from 6 pediatric health systems, PEDSnet. We hypothesized that youth with gender dysphoria would have higher odds of having psychiatric and neurodevelopmental diagnoses than controls. STUDY DESIGN: All youth with a diagnosis of gender dysphoria (n = 4173 age at last visit 16.2 ± 3.4) and at least 1 outpatient encounter were extracted from the PEDSnet database and propensity-score matched on 8 variables to controls without gender dysphoria (n = 16 648, age at last visit 16.2 ± 4.8) using multivariable logistic regression. The odds of having psychiatric and neurodevelopmental diagnoses were examined using generalized estimating equations. RESULTS: Youth with gender dysphoria had higher odds of psychiatric (OR 4.0 [95% CI 3.8, 4.3] P < .0001) and neurodevelopmental diagnoses (1.9 [1.7, 2.0], P < .0001). Youth with gender dysphoria were more likely to have a diagnosis across all psychiatric disorder subcategories, with particularly high odds of mood disorder (7.3 [6.8, 7.9], P < .0001) and anxiety (5.5 [5.1, 5.9], P < .0001). Youth with gender dysphoria had a greater odds of autism spectrum disorder (2.6, [2.2, 3.0], P < .0001). CONCLUSIONS: Youth with gender dysphoria at large pediatric health systems have greater odds of psychiatric and several neurodevelopmental diagnoses compared with youth without gender dysphoria. Further studies are needed to evaluate changes in mental health over time with access to gender affirming care.

Sexual Behaviors Associated with HIV Transmission Among Transgender and Gender Diverse Young Adults: The Intersectional Role of Racism and Transphobia.

HIV prevalence and engagement in sexual behaviors associated with HIV transmission are high among transgender people of color. Per intersectionality, this disproportionate burden may be related to both interpersonal and structural racism and transphobia. The goal of this study was to estimate the association between interpersonal and structural discrimination and sexual behaviors among transgender and gender diverse (TGD) U.S. young adults. We used logit models with robust standard errors to estimate the individual and combined association between interpersonal and structural racism and transphobia and sexual behaviors in a national online sample of TGD young adults of color (TYAOC) aged 18-30 years (N = 228). Racism was measured at the interpersonal and structural level using the Everyday Discrimination Scale and State Racism Index, respectively. Transphobia was measured at the interpersonal and structural level using the Gender Minority Stress Scale and the Gender Identity Tally, respectively. We found that interpersonal racism was associated with transactional sex, and interpersonal transphobia was associated with alcohol/drug consumption prior to sex and transactional sex among TYAOC. We also found evidence of a strong joint association of interpersonal and structural racism and transphobia with alcohol/drug consumption prior to sex (OR 3.85, 95% CI 2.12, 7.01) and transactional sex (OR 3.54, 95% CI 0.99, 12.59) among TYAOC. Racism and transphobia have a compounding impact on sexual behaviors among TYAOC. Targeted interventions that reduce discrimination at both the interpersonal and structural level may help reduce the HIV burden in this marginalized population.

Characterizing the PrEP Continuum for Black and Latinx Sexual and Gender Minority Youth.

Pre-exposure prophylaxis (PrEP) rollout efforts thus far have inadequately reached young people from underrepresented backgrounds. This study explores PrEP engagement among young Black and Latinx men who have sex with men, transgender women, and gender diverse individuals in three U.S. cities using an adapted PrEP continuum measure. We analyze data from the recruitment phase of an ongoing PrEP engagement intervention (n = 319) using partial proportional odds logistic regression. Participants reported high willingness and intention to use PrEP, yet most (82%) were not currently taking PrEP. Being insured (aOR = 2.95, 95%-CI = 1.60-5.49), having one or more PrEP users in one's sexual network (aOR = 4.19, 95%-CI = 2.61-6.79), and higher individual HIV risk scores (aOR = 1.62, 95%-CI = 1.34-1.97) were each associated with being further along the PrEP continuum. Strategies are needed to address barriers to healthcare access and leverage connections within social and sexual networks in order to bolster PrEP engagement among marginalized young people from diverse backgrounds.

RESUMEN: Los esfuerzos de dar a conocer la profilaxis prexposición (PrEP) hasta el momento han llegado de forma inadecuada a los jóvenes de entornos desfavorecidos. Este estudio explora en tres ciudades de los EE. UU. el compromiso con la PrEP entre los jóvenes de raza negra y latino quienes son minorías sexuales o de género, utilizando una medida de seguimiento de la PrEP adaptada. Analizamos los datos de la fase de reclutamiento de una participación en la PrEP en curso (n = 319) utilizando una regresión logística parcial de probabilidades proporcionales. Los participantes manifestaron una alta disposición e intención de utilizar la PrEP, aunque la mayoría (82%) no tomaba actualmente la PrEP. Estar asegurado (aOR = 2,95, 95%-CI = 1,60­5,49), tener uno o más usuarios de la PrEP en su red sexual (aOR = 4,19, 95%-CI = 2,61­6,79), y mayores puntuaciones individuales de riesgo de VIH (aOR = 1,62, 95%-CI = 1,34­1,97) se asociaron con el hecho de llevar un seguimiento estrecho con la PrEP. Se necesitan estrategias para abordar las barreras de acceso a la atención médica y aprovechar las conexiones entre las redes sociales y las de carácter sexual, con el fin de reforzar el compromiso con la PrEP entre los jóvenes marginados de diversas procedencias.

The Impact of the COVID-19 Pandemic on Sexually Transmitted Infection/Human Immunodeficiency Virus Testing Among Adolescents in a Large Pediatric Primary Care Network.

ABSTRACT: Disruptions in sexually transmitted infection (STI) testing infrastructure during the COVID-19 pandemic threaten to impact STI service delivery for adolescents. Within a large pediatric primary care network, we compared STI testing encounters between the pandemic period and an analogous prepandemic period. The STI test counts decreased and test positivity increased during the pandemic period.

Mental Health, Social Influences, and HIV Pre-exposure Prophylaxis (PrEP) Utilization Among Men and Transgender Individuals Screening for HIV Prevention Trials.

The effects of mental health comorbidities and social support on the HIV pre-exposure prophylaxis (PrEP) care continuum are unknown. We conducted a cross-sectional study of men and transgender individuals, ≥ 18 years-old, with ≥ 2 male or transgender partners, or recent condomless anal intercourse. Surveys assessed demographics, mental health treatment, depressive symptomatology, social support, and PrEP-related social contacts. Logistic regression assessed associations between these factors and PrEP uptake and persistence. Participants (n = 247) were 89% cis-male and 46% African-American. Median age was 27 (IQR:23-33). Thirty-seven percent had ever used PrEP, of whom 18% discontinued use. High depressive symptomology was identified in 11% and 9% were receiving mental health treatment. There were no significant associations between depressive symptoms or mental health treatment on the odds of PrEP uptake or discontinuation. Each additional PrEP contact conferred a greater odds of uptake (aOR:1.24, 95% CI: 1.09-1.42). Network-level targets may produce fruitful interventions to increase PrEP uptake.

Feasibility and acceptability of a pilot tailored text messaging intervention for adolescents and young adults completing cancer treatment.

PURPOSE: Despite cure, adolescents and young adults (AYA) who complete cancer treatment remain at risk for numerous physical and psychological late effects. However, engagement in recommended follow-up care, knowledge of cancer treatment history and risks, and adoption of health promoting behaviors are often suboptimal. The pilot randomized controlled trial assessed the feasibility and acceptability of a text messaging intervention (THRIVE; Texting Health Resources to Inform, motiVate, and Engage) designed to promote well-being, and health knowledge and behaviors. METHODS: Sixty-one AYA who recently completed cancer therapy enrolled and were randomized to receive THRIVE (n = 31) or an AYA survivor handbook (n = 30). Participants from both groups completed baseline measures and follow-up surveys 16 weeks later. AYA randomized to THRIVE received one to two health-related text messages per day over 16 weeks. RESULTS: THRIVE demonstrated a high level of acceptability and feasibility. Exploratory analyses highlighted promising improvements in knowledge, fruit/vegetable intake, and perceptions of health vulnerability. CONCLUSIONS: Text messaging is an acceptable and feasible intervention approach for improving well-being and health of AYA survivors. Future research is needed to test the impact of text messaging in a larger trial, including whether or not such an intervention can improve clinical outcomes, such as survivors' engagement in follow-up care.

Comparing Different Measures of Retention in Care Among a Cohort of Adolescents and Young Adults Living with Behaviorally-Acquired HIV.

Young people living with HIV (YLWH) have some of the lowest rates of retention in HIV care, putting them at risk for negative health outcomes. To better understand retention in care in this age group, we conducted a retrospective cohort analysis of YLWH initiating care at a multidisciplinary, adolescent-focused HIV clinic (N = 344). Retention was calculated using a variety of definitions, and relationships between different definitions were assessed. During the 1-year study period, on average YLWH missed two scheduled appointments, and attended 80% of appointments, usually at least once every 3 months. About one-quarter experienced a 6-month gap in care and about two-thirds met the Health Resources and Services Administration's retention criteria. Although most retention definitions were significantly correlated, not all were. Researchers, clinicians, and policymakers should consider the impact of varying definitions of retention, in order to optimally measure this outcome in YLWH, a key vulnerable population.

Predictors of Internet Health Information-Seeking Behaviors Among Young Adults Living With HIV Across the United States: Longitudinal Observational Study.

BACKGROUND: Consistent with young adults' penchant for digital communication, young adults living with HIV use digital communication media to seek out health information. Understanding the types of health information sought online and the characteristics of these information-seeking young adults is vital when designing digital health interventions for them. OBJECTIVE: This study aims to describe characteristics of young adults living with HIV who seek health information through the internet. Results will be relevant to digital health interventions and patient education. METHODS: Young adults with HIV (aged 18-34 years) self-reported internet use during an evaluation of digital HIV care interventions across 10 demonstration projects in the United States (N=716). Lasso (least absolute shrinkage and selection operator) models were used to select characteristics that predicted whether participants reported seeking general health and sexual and reproductive health (SRH) information on the internet during the past 6 months. RESULTS: Almost a third (211/716, 29.5%) and a fifth (155/716, 21.6%) of participants reported searching for general health and SRH information, respectively; 26.7% (36/135) of transgender young adults with HIV searched for gender-affirming care topics. Areas under the curve (>0.70) indicated success in building models to predict internet health information seeking. Consistent with prior studies, higher education and income predicted health information seeking. Higher self-reported antiretroviral therapy adherence, substance use, and not reporting transgender gender identity also predicted health information seeking. Reporting a sexual orientation other than gay, lesbian, bisexual, or straight predicted SRH information seeking. CONCLUSIONS: Young adults living with HIV commonly seek both general health and SRH information online, particularly those exploring their sexual identity. Providers should discuss the most commonly sought SRH topics and the use of digital technology and be open to discussing information found online to better assist young adults with HIV in finding accurate information. Characteristics associated with health information-seeking behavior may also be used to develop and tailor digital health interventions for these young adults.

Pediatric Emergency Provider Sexually Transmitted Infection Screening Practices in Adolescents With Oropharyngeal or Anorectal Chief Complaints.

OBJECTIVES: Sexually transmitted infections (STIs) may present with oropharyngeal or anorectal symptoms. Little is known about the evaluation of adolescents with these complaints in the pediatric emergency department (PED). This study aimed to determine the frequency of and factors associated with STI consideration and testing in this population. METHODS: Retrospective chart review of patients aged 13 to 18 years who presented to an urban PED with oropharyngeal or anorectal chief complaints between June 2014 and May 2015. Sexually transmitted infection consideration was defined as sexual history documentation, documentation of STI in differential diagnosis, and/or diagnostic testing. Multivariate logistic regression models were used to identify factors associated with consideration. RESULTS: Of 767 visits for oropharyngeal (89.4%), anorectal (10.4%), or both complaints, 153 (19.9%) had STI consideration. Of the 35 visits (4.6%) that included gonorrhea and/or chlamydia testing, 12 (34.3%) included testing at the anatomic site of complaint. Of those 12 tests, 50.0% were the incorrect test. Patients with older age (adjusted odds ratio [aOR] = 1.5, 95% confidence interval [CI] = 1.3-1.7), female sex (aOR = 1.6, 95% CI = 1.03-2.5), or anorectal complaints (aOR = 2.4, 95% CI = 1.3-4.3) were more likely to have STI consideration. CONCLUSIONS: In an urban PED, only 20% of visits for adolescents with oropharyngeal or anorectal symptoms included STI consideration. Testing was performed in only 5% of cases and often at an inappropriate anatomic site or with the incorrect test. Interventions to increase awareness of appropriate STI consideration and testing for individuals presenting with possible extragenital complaints may help reduce STIs among adolescents.

Barriers and Facilitators of PrEP Adherence for Young Men and Transgender Women of Color.

We aimed to discover barriers and facilitators of HIV pre-exposure prophylaxis (PrEP) adherence in young men and transgender women of color who have sex with men (YMSM/TW). Short-term and sustained adherence were measured by urine tenofovir concentration and pharmacy refills, respectively. Optimal adherence was defined as having both urine tenofovir concentration consistent with dose ingestion within 48 h and pharmacy refills consistent with ≥ 4 doses per week use. Participants completed semi-structured interviews exploring adherence barriers and facilitators. Participants (n = 31) were primarily African-American (68%), mean age 22 years (SD: 1.8), and 48% had optimal adherence. Adherence barriers included stigma, health systems inaccessibility, side effects, competing stressors, and low HIV risk perception. Facilitators included social support, health system accessibility, reminders/routines, high HIV risk perception, and personal agency. Our findings identify targets for intervention to improve PrEP adherence in these populations, including augmenting health activation and improving accuracy of HIV risk perception.

The Impact of Cell Phone Support on Psychosocial Outcomes for Youth Living with HIV Nonadherent to Antiretroviral Therapy.

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.

Internet and Social Media Access Among Youth Experiencing Homelessness: Mixed-Methods Study.

BACKGROUND: Youth experiencing homelessness are at a risk for a variety of adverse outcomes. Given the widespread use of the internet and social media, these new technologies may be used to address their needs and for outreach purposes. However, little is known about how this group uses these resources. OBJECTIVE: This study investigated how homeless adolescents use these technologies for general and health-related purposes, whether the scope of their use changes with housing status, and their interest in a website dedicated to youth experiencing homelessness. METHODS: A convenience sample of youth aged 18 to 21 years was recruited from a youth-specific homeless shelter. All participants completed a 47-item survey, with 10 individuals completing a semistructured interview. Descriptive statistics, exact testing, logistic regression, and generalized estimating equation modeling was performed for quantitative data analysis. Interviews were transcribed verbatim, and NVivo 10 (QSR International) was employed to facilitate double coding and thematic analysis. RESULTS: A total of 87 participants completed the survey with a mean age of 19.4 (SD 1.1) years. While experiencing homelessness, 56% (49/87) accessed the internet at least once a day, with 86% (75/87) accessing once a week. Access to a smartphone was associated with a 3.03 greater odds of accessing the internet and was the most frequently used device (66% of participants, 57/87). While experiencing homelessness, subjects reported a 68% decreased odds in internet access frequency (odds ratio [OR] 0.32, P<.001), 75% decreased odds in spending greater amounts of time on the internet (OR 0.25, P<.001), and an 87% decreased odds of social media use (OR 0.13, P=.01). Ten participants completed the semistructured interview. Several themes were identified, including (1) changes in internet behaviors while experiencing homelessness, (2) health status as a major concern and reason for Internet use, and (3) interest in a website dedicated to youth experiencing homelessness. While experiencing homelessness, participants indicated their behaviors were more goal-oriented and less focused on leisure or entertainment activities. CONCLUSIONS: While homeless youth experience changes in the frequency, amount of time, and specific uses of the internet and social media, study participants were able to access the internet regularly. The internet was used to search health-related topics. Given the importance of smartphones in accessing the internet, mobile-optimized websites may be an effective method for reaching this group.

IknowUshould2: Feasibility of a Youth-Driven Social Media Campaign to Promote STI and HIV Testing Among Adolescents in Philadelphia.

A youth-driven, social media-based campaign aimed at improving knowledge about and increasing testing for sexually transmitted infections (STIs)/HIV among youth 13-17 years old was assessed by: tracking website/social media use throughout the campaign; online survey of knowledge of and attitudes towards STI testing 9 months after campaign launch; and comparing rates of STI testing at affiliated family planning clinics during the 1 year period immediately prior versus 1 year immediately after campaign launch. Over 1,500 youth were reached via social media. Survey results showed 46 % of youth had never been tested, but 70 % intended to test in the next 6 months. While the total number of GC/CT tests conducted and positive results were not significantly different pre- and post-campaign, there was a large increase in the proportion of visits at which Syphilis (5.4 vs. 18.8 %; p < 0.01) and HIV (5.4 vs. 19.0 %; p < 0.01) testing was conducted post-campaign launch. Future campaigns should incorporate lessons learned about engaging younger adolescents, social media strategies, and specific barriers to testing in this age group.

Practices, Beliefs, and Perceived Barriers to Adolescent Human Immunodeficiency Virus Screening in the Emergency Department.

OBJECTIVE: Limited data exist regarding knowledge of and compliance to the Centers for Disease Control and Prevention's universal adolescent human immunodeficiency virus (HIV) screening recommendations. Our objective was to assess current guideline knowledge, practice, and perceived barriers to emergency department (ED)-based adolescent HIV screening. METHODS: We administered an anonymous Web-based cross-sectional survey from May 1, 2012, to June 30, 2012, to 1073 physicians from the American Academy of Pediatrics Section on Emergency Medicine LISTSERV. Survey participants were included if they (1) practiced as attending-level physicians, (2) practiced primarily in pediatric emergency medicine or general emergency medicine, and (3) provided clinical care for patients younger than the age of 21 years. The survey examined respondent demographics, knowledge, attitudes, beliefs, practices, and barriers to ED-based HIV screening. Standard descriptive statistics and comparative analyses were performed. RESULTS: A total of 220 responses were obtained; 29 responses were excluded and 191 responses were included in the study. Most of the participants were from urban, free-standing children's hospitals and had an annual ED volume of more than 61,000 patient visits. Respondent knowledge of the Centers for Disease Control and Prevention guidelines was low; less than 40% of the respondents identified correct consent requirements. Only 15.4% of the respondents reported screening for HIV more than 10 times for the prior 6 months. Most frequently cited barriers included concerns for privacy (67.4%), follow-up (67%), and cost-effectiveness (65.4%). Human immunodeficiency virus screening facilitators included availability of health educators (83%), established follow-up (74.7%), and rapid HIV tests (65.2%). CONCLUSIONS: Emergency department clinicians exhibit poor knowledge of adolescent HIV screening recommendations. Current universal screening practices remain low; barriers to screening are numerous. Future efforts should disseminate guideline knowledge, increase rapid HIV testing and health educator availability, as well as reduce adolescent-specific barriers.

Adolescent Preferences for a Pediatric Primary Care-based Sexually Transmitted Infection and HIV Prevention Intervention.

PURPOSE: We sought to elicit perspectives on HIV and sexually transmitted infection (STI) prevention among adolescents with recent STIs in primary care to optimize acceptability and effectiveness in designing a novel HIV/STI prevention intervention. METHODS: We enrolled 13-19 year-olds with recent gonorrhea, chlamydia, trichomonas, and/or syphilis in a multimethods cross-sectional study at two primary care clinics. Participants completed surveys and interviews. We used an integrated analytic approach deductively coding data using the Integrated Behavioral Model, then inductively coding to identify themes not represented in the Integrated Behavioral Model. RESULTS: Participants (n = 35) were 85% cisgender female, 14% cisgender male, 1% transgender female; 25% identified as lesbian, bisexual, or queer. Most (97%) identified as non-Latinx Black. None used condoms consistently, 26% were aware of pre-exposure prophylaxis (PrEP), and 31% were never HIV tested. Five key themes emerged. 1) Mental health was central to HIV prevention behavior uptake and coping with STI diagnosis. 2) Youth desired prevention counseling that allowed decisional autonomy and individualized goal setting. 3) Negative social norms around condoms and absent norms around HIV testing and PrEP limited method uptake. 4) Both confidence and concrete skills were needed to initiate prevention methods. 5) Youth desired education at the time of STI diagnosis to improve subsequent prevention decision making. DISCUSSION: Key intervention design considerations included 1) integrating mental health assessment and referral to services, 2) promoting individualized goal setting, 4) building communication skills, 4) providing navigation and material support for PrEP uptake and HIV testing, and 5) augmenting comprehensive STI and HIV prevention education.

Pubertal Suppression in Early Puberty Followed by Testosterone Mildly Increases Final Height in Transmasculine Youth.

Context: Treatment for transmasculine youth (TMY) can involve testosterone treatment and is sometimes preceded by gonadotropin-releasing hormone agonist (GnRHa) treatment for puberty blockade. GnRHas can increase final height in birth-assigned females with central precocious puberty. Maximizing final adult height (FAH) is an important outcome for many TMY. Objective: Our objective was to determine how GnRHa treatment before testosterone impacts FAH. Methods: Retrospective cohort study at 5 US transgender health clinics. Participants were 32 TMY treated with GnRHas in early to midpuberty before testosterone (GnRHa + T group) and 62 late/postpubertal TMY treated with testosterone only (T-only group). Results: The difference between FAH minus midparental target height (MPTH) was +2.3 ± 5.7 cm and -2.2 ± 5.6 cm in the GnRHa + T and T-only groups, respectively (P < .01). In the GnRHa + T group, FAH was 1.8 ± 3.4 cm greater than predicted adult height (PAH) (P < .05) and FAH vs initial height (IH) z-score was 0.5 ± 1.2 vs 0.16 ± 1.0 (P < .05). After adjusting for patient characteristics, each additional month of GnRHa monotherapy increased FAH by 0.59 cm (95% CI 0.31, 0.9 cm), stage 3 breast development at start of GnRHa was associated with 6.5 cm lower FAH compared with stage 2 (95% CI -10.43, -2.55), and FAH was 7.95 cm greater in the GnRHa + T group than in T-only group (95% CI -10.85, -5.06). Conclusion: Treatment with GnRHa in TMY in early puberty before testosterone increases FAH compared with MPTH, PAH, IH, and TMY who only received testosterone in late/postpuberty. TMY considering GnRHas should be counseled that GnRHas may mildly increase their FAH if started early.

Mental Health Diagnoses and Suicidality Among Transgender Youth in Hospital Settings.

Purpose: The purpose of this analysis is to: 1) describe the most common mental health diagnoses in the emergency department (ED) and inpatient hospital settings among transgender and gender diverse (TGD) youth vs. matched controls and 2) evaluate if a gender-affirming hormone therapy (GAHT) or gonadotropin-releasing hormone agonist (GnRHa) prescription decreased the risk of suicidality within these settings. Methods: Using the PEDSnet dataset (years 2009-2019), TGD youth aged 8-18 (n = 3414, with a median age at last visit of 16.2 [14.4, 17.7] years, were propensity-score matched to controls (n = 13,628, age 16.6 [14.2, 18.3] years). Relative risks of the most common mental health diagnoses within ED and inpatient settings were calculated for TGD youth compared with controls. Recurrent time-to-event analysis was used to examine whether GAHT or GnRHa attenuated the risk of suicidality among subsamples of TGD youth. Results: TGD youth had a higher relative risk (95% confidence interval [CI]) of mental health diagnoses and suicidality in the ED (5.46 [4.71-6.33]) and inpatient settings (6.61 [5.28-8.28]) than matched controls. TGD youth prescribed GAHT had a 43.6% lower risk of suicidality (hazard ratio [HR] = 0.564 [95% CI 0.36-0.89]) compared with those never prescribed GAHT during our study period or before GAHT initiation. TGD youth who were prescribed GnRHa therapy had a nonstatistically significant reduction in ED or inpatient suicidality diagnoses compared with those never prescribed GnRHa (HR = 0.79 [0.47-1.31]). Conclusion: Although risk of mental health diagnoses and suicidality in ED and inpatient settings was high among TGD youth, a GAHT prescription was associated with a significant reduction in suicidality risk.

Estimating Transgender and Gender-Diverse Youth Populations in Health Systems and Survey Data.

OBJECTIVES: To identify and examine demographic variation in estimates of gender-diverse youth (GDY) populations from the PEDSnet learning health system network and the Youth Risk Behavior Survey (YRBS). METHODS: The PEDSnet sample included 14- to 17-years-old patients who had ≥2 encounters at a member institution before March 2022, with at least 1 encounter in the previous 18 months. The YRBS sample included pooled data from 14- to 17-year-old in-school youth from the 2017, 2019, and 2021 survey years. Adjusted logistic regression models tested for associations between demographic characteristics and gender dysphoria (GD) diagnosis (PEDSnet) or self-reported transgender identity (YRBS). RESULTS: The PEDSnet sample included 392 348 patients and the YRBS sample included 270 177 youth. A total of 3453 (0.9%) patients in PEDSnet had a GD diagnosis and 5262 (1.9%) youth in YRBS self-identified as transgender. In PEDSnet, adjusted logistic regression indicated significantly lower likelihood of GD diagnosis among patients whose electronic medical record-reported sex was male and among patients who identified as Asian, Black/African American, and Hispanic/Latino/a/x/e. In contrast, in the YRBS sample, only youth whose sex was male had a lower likelihood of transgender identity. CONCLUSIONS: GDY are underrepresented in health system data, particularly those whose electronic medical record-reported sex is male, and Asian, Black/African American, and Hispanic/Latino/a/x/e youth. Collecting more accurate gender identity information in health systems and surveys may help better understand the health-related needs and experiences of GDY and support the development of targeted interventions to promote more equitable care provision.
