Resumo

Although emergence of gender dysphoria at puberty is long established, a distinct pathway of rapid onset gender dysphoria was recently hypothesized based on parental data. Using adolescent clinical data, we tested a series of associations that would be consistent with this pathway, however, our results did not support the rapid onset gender dysphoria hypothesis. Although emergence of gender dysphoria at puberty is long established, a distinct pathway of rapid onset gender dysphoria was recently hypothesized based on parental data.

Puberty has long been understood as one period when gender dysphoria often first emerges.1World Professional Association for Transgender HealthStandards of care for the health of transsexual, transgender, and gender nonconforming people (7th version) [Internet].https://www.wpath.org/publications/socDate: 2012Date accessed: May 30, 2021Google Scholar Although most transgender (trans) older adolescents and adults report needing gender-affirming medical care (hormones and/or surgeries), and also report having been aware of their gender at young ages,2Scheim A.I.

This discussion has occurred primarily in the context of data from a single online parental survey.10Littman L.

Specifically, rapid onset gender dysphoria is hypothesized as a phenomenon in youth with gender dysphoria emerging at or after puberty, socially influenced through peer contagion, and with contributing factors including poor mental health, neurodevelopmental disabilities, parent-child conflict, and maladaptive coping strategies.10Littman L. Parent reports of adolescents and young adults perceived to show signs of a rapid onset of gender dysphoria.PLoS One. 2018; 13: e0202330Google Scholar,11Littman L. Correction: parent reports of adolescents and young adults perceived to show signs of a rapid onset of gender dysphoria.PLoS One. 2019; 14: e0214157Google Scholar If the rapid onset gender dysphoria hypothesis indeed characterizes a distinct clinical phenomenon, and these youth access referrals for hormone suppression or gender-affirming hormones, then we would expect to see differentiation within clinical samples between those with more-recent (ie, rapid-onset) vs more-remote knowledge regarding their gender. Based on the published hypothesis,10Littman L. Parent reports of adolescents and young adults perceived to show signs of a rapid onset of gender dysphoria.PLoS One. 2018; 13: e0202330Google Scholar we would expect more recent gender knowledge to be associated with self-reported mental health measures, mental health and neurodevelopmental disability diagnoses, behaviors consistent with maladaptive coping (eg, self-harm), support from online and/or transgender friends but not parents, and lesser gender dysphoria. We aim to test these hypotheses. Baseline data (2017-2019) from the Trans Youth CAN! Cohort included pubertal/postpubertal adolescents age <16 years attending a first referral visit for hormone suppression or gender-affirming hormones at 10 Canadian medical clinics that provide specialized gender-affirming care to adolescents through a range of different care models. Ethics approval was received from all study sites. Years gender was known was missing for 1 participant (excluded), for a final sample of n = 173. Methods and measures are described in detail elsewhere.18Bauer G.R. Pacaud D. Couch R. Metzger D.L. Gale L.

As ages were whole numbers, a difference of 1 could indicate <1 year to just under 2 years. Values ≤1 were coded as recent gender knowledge, with an alternate definition (values ≤2) for sensitivity analysis. Mental health symptoms were assessed with the Overall Anxiety Severity and Impairment Scale,21Campbell-Sills L. Norman S.B. Craske M.G. Sullivan G. Lang A.J.

Three measures captured social connections to online and trans communities: having gender-supportive online friends was coded if adolescents reported online friends who knew their gender and were "very supportive," and having online or trans friends as general sources of support was indicated in checklist items. Parental support was coded if youth indicated all biological/step/foster parents were "very supportive" of their gender identity or expression. Statistical analyses were conducted using SAS v 9.4.1 (SAS Institute, Inc), weighted to account for clinics' different recruitment periods due to staggered start dates, to improve generalizability.18Bauer G.R.

Gotovac S. et al.Transgender youth referred to clinics for gender-affirming medical care in Canada.Pediatrics. 2021; 148 (e2020047266)Google Scholar For analyses of associations between recency of gender knowledge and hypothesized correlates, a series of multiple regressions was conducted, with recency as the independent variable of interest, controlling for age and sex assigned at birth. Linear regressions were used for continuous dependent variables (eg, psychometric scales). For dichotomous dependent variables, modified Poisson regression with robust variance estimation was used.25Zou G. A modified Poisson regression approach to prospective studies with binary data.Am J Epidemiol. 2004; 159: 702-706Google Scholar As "rapid-onset" has not been precisely defined, we conducted a sensitivity analysis repeating these analyses using the alternate (value ≤2) definition of recent gender knowledge. Recency of gender knowledge is presented in the Figure, results of hypothesized associations (recency value ≤ 1) in Table I, and variable means and frequencies in Table II (available at www.jpeds.com). Controlling for age and sex assigned at birth, recent gender knowledge was not significantly associated with depressive symptoms, psychological distress, past diagnoses with mental health issues or neurodevelopmental disorders, gender dysphoria symptoms, self-harm, past-year suicide attempt, having gender-supportive online friends, general support from online friends or transgender friends, or gender support from parents. Recent gender knowledge was associated with lower scores on anxiety severity/impairment (b = −3.272; 95% CI −5.172, −1.373), and lower prevalence of marijuana use (prevalence ratio = 0.11; 95% CI 0.02, 0.82), counter to hypothesized directions of effect. For sensitivity analysis using the alternate (value ≤2) definition of recent gender knowledge, we found all results substantively the same in statistical significance and direction of effect, except past-year marijuana use, which now only approached statistical significance (P = .0677).Table IAssociations between short-term awareness of gender and variables hypothesized to be associated with rapid-onset gender dysphoria, controlling for age and sex assigned at birthDependent variablesB∗Estimates adjusted for age in years and sex assigned at birth.SEPPR∗Estimates adjusted for age in years and sex assigned at birth.95% CI†95% CIs for betas (for linear regressions) or PRs (for modified Poisson regressions).Mental health scales Anxiety severity/impairment (OASIS)−3.2720.961.0008(−5.172, −1.373) Depressive symptoms (MDS)−1.2760.845.1328(−2.944, 0.392) Psychological distress (K6)−1.1561.060.2771(−3.248, 0.936)Record of diagnosis with mental health disorder‡Extracted from medical record: any diagnosis from clinic or referrer of anxiety, depression, personality disorder, eating disorder.

Gender Distress Scale. We did not find support within a clinical population for a new etiologic phenomenon of rapid onset gender dysphoria during adolescence. Among adolescents under age 16 years seen in specialized gender clinics, associations between more recent gender knowledge and factors hypothesized to be involved in rapid onset gender dysphoria were either not statistically significant, or were in the opposite direction to what would be hypothesized. This putative phenomenon was posited based on survey data from a convenience sample of parents recruited from websites,10Littman L. Parent reports of adolescents and young adults perceived to show signs of a rapid onset of gender dysphoria.PLoS One. 2018; 13: e0202330Google Scholar and may represent the perceptions or experiences of those parents, rather than of adolescents, particularly those who may enter into clinical care. Similar analyses should be replicated using additional clinical and community data sources. Our finding of lower anxiety severity/impairment scores in adolescents with more recent gender knowledge suggests the potential for longstanding experiences of gender dysphoria (or their social complications) playing a role in development of anxiety, which could also be explored in future research.
