Over the last decade, several child and adolescent gender iden-
tity services have reported an increase in young people who
seek help with incongruence between the experienced gender
identity and the gender to which they were assigned at birth
(Aitken etal., 2015; Wood etal., 2013). Many of those, but not
all, would meet the diagnostic criteria for gender dysphoria
(GD) (APA, 2013). It has been suggested that this increase
is mostly due to an influx of birth-assigned females coming
forward. Aitken etal. (2015) reported a significant temporal
shift in the sex ratio of clinic-referred gender-diverse youth to
Toronto and Amsterdam, from a ratio favoring males prior to
2006, to a ratio favoring assigned females from 2006 to 2013.
The national Gender Identity Development Service (GIDS)
in the UK is the largest child and adolescent specialist gen-
der service in the world, seeing young people up to the age of
18. Historically, more birth-assigned males were presenting
to GIDS in childhood and adolescence (Di Ceglie, Freedman,
McPherson, & Richardson, 2002). However, in a more recent
study, adolescent referrals to GIDS favored birth-assigned
females (de Graaf etal., 2017; Holt, Skagerberg, & Dunsford,
Gender-diverse young people often present with psycho-
logical difficulties. Compared to children, a greater percent-
age of gender-diverse adolescents have psychological difficul-
ties in the clinical range (Steensma etal., 2014). The level of
psychological well-being for birth-assigned males and females
referred in childhood are often comparable (Steensma etal.,
2014). In adolescents, however, gender differences in psycho-
logical functioning are noted more frequently. The literature
suggests that birth-assigned males tend to show more internaliz-
ing difficulties in the clinical range than birth-assigned females
(de Vries, Steensma, Cohen-Kettenis, VanderLaan, & Zucker,
2016). However, more recently, increased psychopathology
was also reported for gender-diverse birth-assigned females
(de Graaf etal., 2017; Kaltiala-Heino, Sumia, Työläjärvi, &
Lindberg, 2015).
The current study aimed to examine the sex ratio in the num-
ber of children and adolescents referred to GIDS over the past
7years and to investigate whether any gender differences can be
found in terms of psychological functioning and age at referral.
For this retrospective review of GIDS referrals, exemption
for ethics was confirmed by external and local ethics commit-
tees affiliated with the Tavistock and Portman NHS Research
and Development Department. Between January 1, 2009,
and December 31, 2016, a total of 4506 young people, aged
between 1 and 18years, were referred to GIDS. Age at refer-
ral and birth-assigned gender were collected at time of refer-
ral. The sex ratio for children and adolescents was tested for
significance using the binomial test. Age at referral was ana-
lyzed per year using independent t tests. The Child Behavior
Checklist (CBCL), which was completed by the parent during
the assessment phase, was used to measure internalizing and
externalizing clinical range scores (T scores > 63) (Achenbach
& Edelbrock, 1983). The CBCL data were analyzed by birth-
assigned gender in children and adolescents using a chi-square
test with a two-tailed p value. CBCL data were available for
39% of all child cases. In the adolescent sample, 60% had a
completed CBCL. One explanation for the high number of
missing CBCL data could have to do with service users not

always returning questionnaires when receiving these after their
first appointment. The higher percentage of missing data in the
child group could relate to the fact that a greater proportion of
younger children may not be seen as frequently as adolescents,
and possibly dropout during the assessment phase.
Characteristics of GIDS referrals, of which the vast majority
(84%) were adolescents, are shown in Table1. A significant
difference by the binomial test, p < .001, showed that the sex
ratio in children favored birth-assigned males (M/F, 1.31:1),
whereas in adolescents referrals favored birth-assigned females
(M/F, 1:2.12), binomial test, p < .001. Interestingly, in both
children and adolescents, the average increase rate of referrals
was higher for birth-assigned females, as displayed in Fig.1.
For age at referral in children, birth-assigned males were,
on average, referred at a younger age, t(717) = 4.05, p < .001,
whereas in adolescents birth-assigned females were younger,
t(3785) = − 2.91, p < .005. No significant differences were
found over time, which indicates that the age at referral for
birth-assigned males and birth-assigned females in children and
adolescents has remained stable over the last 7years.
With regard to psychological functioning, a signifi-
cantly greater percentage of adolescents had Internalizing
problems in the clinical range compared to children, χ2(1,
N = 1696) = 12.02, p < .001. For this comparison, however,
there is a sex difference: the difference between children and
adolescents is significant only for birth-assigned females, χ2(1,
N = 1127) = 11.17, p < .001, and not for birth-assigned males,
χ2(1, N = 569) = .37, p = .54. On the other hand, Externalizing
problems were significantly more prevalent in children than
in adolescents, χ2(1, N = 1696) = 39.92, p < .001. For adoles-
cents, a greater percentage of birth-assigned females showed
Internalizing problems in the clinical range compared to birth-
assigned males, χ2(1, N = 1468) = 16.47, p < .001, whereas a
significantly greater percentage of birth-assigned males scored
in the Externalizing clinical range compared to birth-assigned
females, χ2(1, N = 1468) = 4.36, p < .05. For children, no sig-
nificant gender differences were found on both Internalizing,
χ2(1, N = 228) = .01, p = .91, and Externalizing scales, χ2(1,
N = 228) = .00, p = 1.0.
The UK has witnessed an unprecedented increase in referrals
of gender-diverse young people seeking professional help. Both
in children and adolescents the rise in referrals was steeper for
birth-assigned females compared to birth-assigned males. This
has resulted in an inversion in sex ratio in adolescent referrals
and an evening out of birth-assigned male and female refer-
rals in childhood. While the overall number of birth-assigned
female referrals has increased, the age at which referrals were
made did not change over time.

Compared to international data reported by other gender
identity clinics, the sex ratio of the child referrals in the UK was
more in line with the child sex ratio reported by the Amster-
dam clinic (1.25:1, N = 860) than with the Toronto clinic, which
reported a larger proportion of birth-assigned males referred
in childhood (4.33:1, N = 624) (Steensma, Cohen-Kettenis, &
Zucker, 2018). While across all three clinics birth-assigned boys
were significantly younger than the referred girls in childhood,
the mean age of the children referred in Toronto was signifi-
cantly younger at referral compared to Amsterdam and the UK.
As suggested by de Vries etal. (2016), these outcomes could
reflect that there are cultural differences between North America
and Europe, specifically with regard to tolerance or acceptance
of gender-diverse behavior, particularly in birth-assigned boys.
For adolescents, our findings reflect the general trend of an
inversion in sex ratios reported both in Amsterdam and Toronto
(in Amsterdam: 1:1.72, N = 234; in Toronto: 1:1.76, N = 202;
Aitken etal., 2015), in the U.S. (1:1.4, N = 180; Reisner etal.,
2015), and more pronounced in Germany (1:2.9, N = 39;
Becker, Ravens-Sieberer, Ottová-Jordan, & Schulte-Markwort,
2017) and Finland (1:6.8, N = 49; Kaltiala-Heino etal., 2015).
There are various explanations put forward in the literature
contemplating the increase in birth-assigned females. Some
have suggested that differences in normative sex development,
in which birth-assigned females experience pubertal changes at
an earlier age than birth-assigned males, might have an impact
on the greater number of adolescent birth-assigned females
coming forward (Aitken etal., 2015). However, as the increase
in birth-assigned female referrals was found across the age
range, arguments around timing of puberty cannot fully explain
the rising number of birth-assigned females. Several clinical
observations suggest that pre-pubertal young people, specifi-
cally girls, may experience adversity toward puberty (Harris,
2004; Lesko, 2012; Pinto, 2007). Therefore, rather than the
experience of puberty, could we argue that birth-assigned
females in childhood are increasingly more worried about the
thought of puberty?
Other arguments regarding the influx in birth-assigned
females suggest that, given the increased awareness and vis-
ibility of declaring trans identities, “coming out” in this context
may be easier for birth-assigned females than it is for birth-
assigned males (Aitken etal., 2015). This argument can be
supported by the claim that gender-variant behavior in birth-
assigned males may be more exposing and can lead to social
stigma (Shiffman etal., 2016).
Additionally, the digitalization of the ways in which young
people and society communicate should not be underestimated.
Social media is increasingly used as a platform to seek peer
group belonging and support, especially by adolescent girls
(Barker, 2009). In the current context, with increasingly more
birth-assigned females referred to gender services present-
ing with psychopathology, could we argue that influences of
socially constructed views of “femininity” and “masculinity”
and the way these are being displayed on social media may have
an impact on the increase of birth-assigned female referrals,
especially for those who do not feel they fit this stereotype?

Psychopathology in adolescent birth-assigned females is a
topical issue which is currently reported by various interna-
tional gender identity clinics (de Graaf etal., 2017; Kaltiala-
Heino etal., 2015). Not only adolescent girls, also a greater
percentage of referred birth-assigned males presented with
externalizing problems in the clinical range in adolescence,
which could reflect the current changing climate. Whereas
adolescents tend to report more behavioral and emotional
problems than children, in our sample, a greater percentage
of children had externalizing problems in the clinical range
compared to the adolescents. When comparing these findings
to previously published outcomes from the Toronto clinic and
the Amsterdam clinic (Steensma etal., 2014), a greater percent-
age of children in the UK had internalizing and externalizing
problems in the clinical range. The increase in psychopathology
mirrors a general trend of young people in the UK, especially
in adolescent girls (Lessof etal., 2016). A new phenomenon,
however, is the increase in referred birth-assigned females in
late childhood, which is also reported by other gender iden-
tity clinics (Steensma etal., 2018). With the influx of birth-
assigned females starting in childhood, we might expect to see
an increase in behavioral problems in children, especially those
aged 10–12years.
The steep increase in birth-assigned females seeking help
from gender services across the age range highlights an emerg-
ing phenomenon. It is important to follow birth-assigned
females’ trajectories, to better understand the changing clinical
presentations in gender-diverse children and adolescents and to
monitor the influence of social and cultural factors that impact
on their psychological well-being.

Abstract Trends in clinical referrals to specialist gender services historically comprised more assigned male at birth young people. In the last decade, this has shifted in adolescent samples to more assigned female young people. An updated review of the current patterns of referrals is important to better understand the potential changing needs of clinically referred gender-diverse children and adolescents. We assessed the demographics of referrals to the Gender Identity Development Service (GIDS) and their attendance patterns from 2017 to 2020. During this period, 9555 referrals were received in total, most were in adolescence (n = 7901, 82.7%), and more assigned female (age range = 1–18 years; M = 14.05; SD = 2.5) were referred than assigned male young people overall (n = 6823, 71.4%). A larger proportion of assigned female adolescents (assigned female: n = 5835, 62.3%, assigned male: n = 1897, 20.3%) and assigned female children (n = 988, 10.6%, assigned male: n = 640, 6.8%) were referred. For 2%, sex assigned at birth was unrecorded, 83.4% were White British and 36.6% had an unidentified ethnicity. Only 4% did not attend a first appointment, indicating the need for care from this specialist service. With more young people presenting to gender services, understanding the demographics of young people seeking gender care is vital for service provision. Future research should explore how to increase access to gender care for ethnic minorities, and how to support those accessing services.

Media's Stranglehold on Storm and Stress - The Sorrows of Generation Z about Sex and Gender Abstract: The feeling of not belonging to one's birth sex is not new; one can trace this phenomenon back even to ancient mythology. Although it has always been rare, there has recently been a sharp increase in gender identity deviations among adolescents. This text addresses this problem by asking to what extent this development also results from upheavals in the cultural landscape and, above all, in media technology. Do they cause young people to believe they are in the "wrong gender" and, in extreme cases, to strive for transition? We present the most salient cornerstones of the planned German self-determination law (Self-ID), most of which, however, are unlikely to do justice to the underlying problem. The text concludes by describing several unanswered questions concerning this matter and by attempting to propose first answers. The advantages of a gender-exploratory over the trans affirmative therapy approach are summarized.

In this vein, results evidenced that early adults had typically started questioning their gender identity during their teen years. ...

The present study aimed at dimensionally exploring how transgender and non-binary Italian adults identify and express their gender. The Gender Diversity Questionnaire (GDQ) was administered to a sample of 112 adult subjects aged 18–60 years accessing a gender-specialized service in Rome. The majority of the participants were aged 18–24 years (53.6%), whereas fewer subjects were aged 25–35 years (32%) and 35 years and older (14.3%). Most participants (83.9%) identified themselves as trans binary, while the remaining (16.1%) identified as non-binary. Trans binary participants reported a stable gender identity, whereas non-binary participants reported a more fluid gender identity over time and across contexts. Younger subjects recognized the use of chosen names, pronouns, and clothes as important for their gender expression, whereas older subjects attributed more importance to physical appearance and emotions. Differences regarding gender-affirmative interventions emerged between non-binary and transbinary participants. Findings evidence that gender non-conforming adults accessing gender-specialized services have unique needs and features, thus it is essential to shed light on this population by providing greater visibility and recognition.

It is unclear whether the literature on adolescent gender dysphoria (GD) provides evidence to inform clinical decision making adequately. In the final of a series of three papers, we sought to review published evidence systematically regarding the types of treatment being implemented among adolescents with GD, the age when different treatment types are instigated, and any outcomes measured within adolescence. Having searched PROSPERO and the Cochrane library for existing systematic reviews (and finding none at that time), we searched Ovid Medline 1946 -October week 4 2020, Embase 1947-present (updated daily), CINAHL 1983-2020, and PsycInfo 1914-2020. The final search was carried out on 2nd November 2020 using a core strategy including search terms for 'adolescence' and 'gender dysphoria' which was adapted according to the structure of each database. Papers were excluded if they did not clearly report on clinically-likely gender dysphoria, if they were focused on adult populations, if they did not include original data (epidemiological, clinical, or survey) on adolescents (aged at least 12 and under 18 years), or if they were not peer-reviewed journal publications. From 6202 potentially relevant articles (post deduplication), 19 papers from 6 countries representing between 835 and 1354 participants were included in our final sample. All studies were observational cohort studies, usually using retrospective record review (14); all were published in the previous 11 years (median 2018). There was significant overlap of study samples (accounted for in our quantitative synthesis). All papers were rated by two reviewers using the Crowe Critical Appraisal Tool v1·4 (CCAT). The CCAT quality ratings ranged from 71% to 95%, with a mean of 82%. Puberty suppression (PS) was generally induced with Gonadotropin Releasing Hormone analogues (GnRHa), and at a pooled mean age of 14.5 (±1.0) years. Cross Sex Hormone (CSH) therapy was initiated at a pooled mean of 16.2 (±1.0) years. Twenty-five participants from 2 samples were reported to have received surgical intervention (24 mastectomy, one vaginoplasty). Most changes to health parameters were inconclusive, except an observed decrease in bone density z-scores with puberty suppression, which then increased with hormone treatment. There may also be a risk for increased obesity. Some improvements were observed in global functioning and depressive symptoms once treatment was started. The most common side effects observed were acne, fatigue, changes in appetite, headaches, and mood swings. Adolescents presenting for GD intervention were usually offered puberty suppression or cross-sex hormones, but rarely surgical intervention. Reporting centres broadly followed established international guidance regarding age of treatment and treatments used. The evidence base for the outcomes of gender dysphoria treatment in adolescents is lacking. It is impossible from the included data to draw definitive conclusions regarding the safety of treatment. There remain areas of concern, particularly changes to bone density caused by puberty suppression, which may not be fully resolved with hormone treatment.

Introducción. La destransición de género es el acto de detener o revertir los cambios sociales, médicos y/o administrativos con- seguidos durante un proceso de transición de género. Se trata de un fenómeno emergente de gran interés a nivel clínico y social. Método. Se condujo una búsqueda sistemática en siete bases de datos entre 2010 y 2022, se rastrearon manualmente las referencias de los artículos y se consultaron libros especializados. Se realizó un análisis cuantitativo y de contenido. Resultados. Se incluyeron 138 registros, 37% correspondientes a estudios empíricos y 38,4% publicados en 2021. Se identifican al menos ocho términos para hacer referencia a la destransición, con diferencias en sus definiciones. La prevalencia difiere en función del criterio utilizado, siendo menor para la destransición/arrepentimiento (0-13,1%) que para la descontinuación de la asistencia/tratamiento médico (1,9%-29,8%), y menor para la destransición/arrepentimiento tras cirugía (0-2,4%) que para la destransición/arrepentimiento tras tratamiento hormonal (0-9,8%). Se describen más de 50 factores psicológicos, médicos y socioculturales que influyen en la decisión de destransicionar, así como 16 factores predictores/asociados a la destransición. No se encuentran guías de abordaje sanitario ni legislativo. Los debates actuales se centran en los interrogantes sobre la naturaleza de la disforia de género y el desarrollo de la identidad, el papel de los profesionales con respecto al acceso a los tratamientos médicos y el impacto de las destransiciones sobre la futura accesibilidad a dichos tratamientos. Conclusiones. La destransición de género es una realidad compleja, heterogénea, poco estudiada y escasamente comprendida. Se requiere un abordaje y estudio sistemático que permita comprender su prevalencia real, implicaciones y manejo a nivel sanitario.
Purpose: We examined the relationship between parent- and child-reported gender identity of the youth with internalizing symptoms in transgender and gender-diverse (TGD) youth. In addition, we investigated differences in sex assigned at birth ratios and pubertal development stages in TGD and cisgender youth. Methods: We analyzed longitudinal data from the Adolescent Brain Cognitive Development study (ABCD), corresponding to baseline and 1st-to-3rd-year follow-up interviews (n = 6030 to n = 9743, age range [9-13]). Sociodemographic variables, self- and parent-reported gender identity, and clinical measures were collected. Results: TGD youth showed higher levels of internalizing symptoms compared with cisgender youth. However, this was not worsened by discordance in gender identification between TGD youth and parents. Over the 3-year follow-up period, the number of TGD participants increased from 0.8% (95% confidence interval (CI) [0.6-1.0]) at baseline to 1.4% (95% CI [1.1-1.7]) at the 3rd-year follow-up (χ2 = 10.476, df = 1, false discovery rate (FDR)-adjusted p = 0.00256), particularly among those assigned female at birth (AFAB) in relation to people assigned male at birth (AMAB) (AMAB:AFAB at baseline: 1:1.9 vs. AMAB:AFAB at 3rd-year follow-up: 1:4.7, χ2 = 40.357, df = 1, FDR-adjusted p < 0.0001). Conclusions: TGD youth in ABCD reported higher internalizing symptoms than cisgender youth, although this was not affected by parental discordance in gender identification. A substantial increase over time in TGD children AFAB was documented. More research is needed to understand the clinical implications of these preliminary results, for which the longitudinal design of ABCD will be crucial.

Adolescents seeking professional help with their gender identity development often present with psychological difficulties. Existing literature on psychological functioning of gender diverse young people is limited and mostly bound to national chart reviews. This study examined the prevalence of psychological functioning and peer relationship problems in adolescents across four European specialist gender services (The Netherlands, Belgium, the UK, and Switzerland), using the Child Behavioural Checklist (CBCL) and the Youth Self-Report (YSR). Differences in psychological functioning and peer relationships were found in gender diverse adolescents across Europe. Overall, emotional and behavioural problems and peer relationship problems were most prevalent in adolescents from the UK, followed by Switzerland and Belgium. The least behavioural and emotional problems and peer relationship problems were reported by adolescents from The Netherlands. Across the four clinics, a similar pattern of gender differences was found. Birth-assigned girls showed more behavioural problems and externalising problems in the clinical range, as reported by their parents. According to self-report, internalising problems in the clinical range were more prevalent in adolescent birth-assigned boys. More research is needed to gain a better understanding of the difference in clinical presentations in gender diverse adolescents and to investigate what contextual factors that may contribute to this.

The year 10 students who took part in the Longitudinal Study of Young People in England (LSYPE2) in 2014 have been growing up in a rapidly changing environment. The previous cohort of year 10 students, who were interviewed in 2005, lived in a world in which the UK economy had seen 13 years of uninterrupted growth in GDP, and social media and the fast and constantly connected mobile devices that many now take for granted had not yet been fully integrated into young people’s lives. As such, it is perhaps unsurprising that the attitudes and behaviours of year 10 students in 2014 were markedly different to those in 2005. The findings from LSYPE2 are complex and would merit further investigation. However, two fundamental themes emerged from our analyses: • Year 10 students in 2014 were markedly more ‘work focused’ than their counterparts in 2005 • There were signs that the mental wellbeing of year 10 students – particularly that of girls – had worsened and that young people felt less control over their own destinies

This study examined peer relations in adolescents with gender dysphoria, clinical controls, and nonreferred controls. Specifically, we examined group differences in 2 types of bullying experienced (gender identity/sexuality vs. “general” forms), numbers of same- and opposite-sex friends (relative to birth sex), and the influences of bullying and friends on behavioral and emotional problems. Participants (N = 158; M age, 16.94 years, SD = 1.82) completed measures of gender dysphoria, bullying, numbers of same- and opposite-sex friends at school and in the community, and behavioral and emotional problems. The gender-dysphoric and clinical control adolescents reported significantly more behavioral and emotional problems relative to the nonclinical adolescents. When examining the 2 major forms of bullying, the gender-dysphoric adolescents reported more gender/sexual bullying than the 2 other groups, but both the gender-dysphoric group and the clinical control group reported more general bullying than the nonclinical controls. The gender-dysphoric adolescents had fewer same-sex friends, but more opposite-sex friends, compared with controls. In the gender-dysphoric group, gender bullying, general bullying, and fewer same-sex friends at school were all significantly correlated with a greater number of self-reported behavioral and emotional problems. Strategies for reducing behavioral and emotional problems among adolescents with gender dysphoria are discussed. (PsycINFO Database Record (c) 2015 APA, all rights reserved)

This study is the third in a series to examine behavioral and emotional problems in children and adolescents with gender dysphoria in a comparative analysis between two clinics in Toronto, Ontario, Canada and Amsterdam, the Netherlands. In the present study, we report Child Behavior Checklist (CBCL) and Youth Self-Report (YSR) data on adolescents assessed in the Toronto clinic (n = 177) and the Amsterdam clinic (n = 139). On the CBCL and the YSR, we found that the percentage of adolescents with clinical range behavioral and emotional problems was higher when compared to the non-referred standardization samples but similar to the referred adolescents. On both the CBCL and the YSR, the Toronto adolescents had a significantly higher Total Problem score than the Amsterdam adolescents. Like our earlier studies of CBCL data of children and Teacher's Report Form data of children and adolescents, a measure of poor peer relations was the strongest predictor of CBCL and YSR behavioral and emotional problems in gender dysphoric adolescents.

This paper presents findings of a detailed service audit of cases seen at a specialist service for children and adolescents with gender identity disorders. The audit looked at clinical features, associated features, demographic characteristics and complexity of the cases. Data were extracted from patient files of the first 124 cases seen by the service. Clinical features were assessed based on DSM-IV criteria (American Psychiatric Association, 1994) and associated features were based on the clinical features list of the Association of Child Psychology and Psychiatry (ACPP) data set (Berger et al., 1993). A range of results is presented documenting the occurrence and frequency of different clinical features at different ages. These include the finding that stereotypically gendered clothing (i.e. boys cross-dressing and girls refusing to wear skirts) is more significant in pre-pubertal children, whereas dislike of bodily sexual characteristics becomes more predominant in post-pubertal children. The most common associated features were relationship difficulty with parents/carers (57%), relationship difficulty with peers (52%) and depression/misery (42%). Gender identity problems have wide-reaching implications for children and their families and problems may become more entrenched with the onset of puberty. Although specialist support and co-ordination of services becomes essential particularly at this time, interventions in childhood may have the function of preventing difficulties becoming more severe during adolescence.

Increasing numbers of adolescents present in adolescent gender identity services, desiring sex reassignment (SR). The aim of this study is to describe the adolescent applicants for legal and medical sex reassignment during the first two years of adolescent gender identity team in Finland, in terms of sociodemographic, psychiatric and gender identity related factors and adolescent development. Structured quantitative retrospective chart review and qualitative analysis of case files of all adolescent SR applicants who entered the assessment by the end of 2013. The number of referrals exceeded expectations in light of epidemiological knowledge. Natal girls were markedly overrepresented among applicants. Severe psychopathology preceding onset of gender dysphoria was common. Autism spectrum problems were very common. The findings do not fit the commonly accepted image of a gender dysphoric minor. Treatment guidelines need to consider gender dysphoria in minors in the context of severe psychopathology and developmental difficulties.

The number of adolescents referred to specialized gender identity clinics for gender dysphoria appears to be increasing and there also appears to be a corresponding shift in the sex ratio, from one favoring natal males to one favoring natal females. We conducted two quantitative studies to ascertain whether there has been a recent inversion of the sex ratio of adolescents referred for gender dysphoria. The sex ratio of adolescents from two specialized gender identity clinics was examined as a function of two cohort periods (2006-2013 vs. prior years). Study 1 was conducted on patients from a clinic in Toronto, and Study 2 was conducted on patients from a clinic in Amsterdam. Across both clinics, the total sample size was 748. In both clinics, there was a significant change in the sex ratio of referred adolescents between the two cohort periods: between 2006 and 2013, the sex ratio favored natal females, but in the prior years, the sex ratio favored natal males. In Study 1 from Toronto, there was no corresponding change in the sex ratio of 6,592 adolescents referred for other clinical problems. Sociological and sociocultural explanations are offered to account for this recent inversion in the sex ratio of adolescents with gender dysphoria.

Purpose: Adolescence marks a transition point in the development of gender experience and expression. Although there is growing awareness about various gender identities in health research, only limited data on the prevalence of adolescent gender variance in the general population exists. Methods: German female and male adolescents (n = 940) aged 10–16 participating in the nationally representative “Health Behaviour in School-aged Children” (HBSC) Hamburg survey were asked to report their current gender experience (identification as both feminine and masculine) and gender expression (gender role as girl or boy). Two overall categories and five subcategories on gender experience and expression were established based on previous research. Results: In total, 4.1% of the adolescents’ responses were rated as variant in gender experience and 3.0% as nonconforming in expression. Both variant experiences and nonconforming expression together were present in only 0.9% of adolescents. Gender variance was more strongly present in girls as well as in younger age groups. In detail, 1.6% reported an incongruent, 1.1% an ambivalent, and 1.5% no gender identification. Another 8.0% of the responses could be rated as only somewhat congruent. Conclusions: Fluidity between clearly congruent or incongruent pathways is present in adolescence, including variant as well as possibly still developing (only somewhat clear) gender experiences, whereas clearly incongruent identification and nonconforming expression were less frequent. Understanding adolescent gender development as multidimensional is important in order to identify the needs of those who do not fit into the current understanding of either female or male.
Transgender youth represent a vulnerable population at risk for negative mental health outcomes including depression, anxiety, self-harm, and suicidality. Limited data exist to compare the mental health of transgender adolescents and emerging adults to cisgender youth accessing community-based clinical services; the present study aimed to fill this gap. A retrospective cohort study of electronic health record data from 180 transgender patients aged 12-29 years seen between 2002 and 2011 at a Boston-based community health center was performed. The 106 female-to-male (FTM) and 74 male-to-female (MTF) patients were matched on gender identity, age, visit date, and race/ethnicity to cisgender controls. Mental health outcomes were extracted and analyzed using conditional logistic regression models. Logistic regression models compared FTM with MTF youth on mental health outcomes. The sample (N = 360) had a mean age of 19.6 years (standard deviation, 3.0); 43% white, 33% racial/ethnic minority, and 24% race/ethnicity unknown. Compared with cisgender matched controls, transgender youth had a twofold to threefold increased risk of depression, anxiety disorder, suicidal ideation, suicide attempt, self-harm without lethal intent, and both inpatient and outpatient mental health treatment (all p < .05). No statistically significant differences in mental health outcomes were observed comparing FTM and MTF patients, adjusting for age, race/ethnicity, and hormone use. Transgender youth were found to have a disparity in negative mental health outcomes compared with cisgender youth, with equally high burden in FTM and MTF patients. Identifying gender identity differences in clinical settings and providing appropriate services and supports are important steps in addressing this disparity.
