Characteristics of children and adolescents referred to specialist gender services: a systematic review.

BACKGROUND: Increasing numbers of children/adolescents experiencing gender dysphoria/incongruence are being referred to specialist gender services. Services and practice guidelines are responding to these changes. AIM: This systematic review examines the numbers and characteristics of children/adolescents (under 18) referred to specialist gender or endocrinology services. METHODS: Database searches were performed (April 2022), with results assessed independently by two reviewers. Peer-reviewed articles providing at least birth-registered sex or age at referral were included. Demographic, gender-related, mental health, neurodevelopmental conditions and adverse childhood experience data were extracted. A narrative approach to synthesis was used and where appropriate proportions were combined in a meta-analysis. RESULTS: 143 studies from 131 articles across 17 countries were included. There was a twofold to threefold increase in the number of referrals and a steady increase in birth-registered females being referred. There is inconsistent collection and reporting of key data across many of the studies. Approximately 60% of children/adolescents referred to services had made steps to present themselves in their preferred gender. Just under 50% of studies reported data on depression and/or anxiety and under 20% reported data on other mental health issues and neurodevelopmental conditions. Changes in the characteristics of referrals over time were generally not reported. CONCLUSIONS: Services need to capture, assess and respond to the potentially co-occurring complexities of children/adolescents being referred to specialist gender and endocrine services. Agreement on the core characteristics for collection at referral/assessment would help to ensure services are capturing data as well as developing pathways to meet the needs of these children.PROSPERO registration number CRD42021289659.

Care pathways of children and adolescents referred to specialist gender services: a systematic review.

BACKGROUND: Increasing numbers of children and adolescents experiencing gender dysphoria/incongruence are being referred to specialist gender services. However, little is currently known about the proportions accessing different types of care and treatment following referral. AIM: This systematic review examines the range of care pathways of children/adolescents (under 18) referred to specialist gender or endocrinology services. METHODS: Database searches were performed (April 2022), with results assessed independently by two reviewers. Peer-reviewed articles providing data for numbers of children and/or adolescents at referral/assessment and their treatment pathways were included. A narrative approach to synthesis was used and where appropriate proportions were combined in a random-effects meta-analysis. RESULTS: 23 studies across nine countries were included, representing 6133 children and/or adolescents with a median age at assessment of 14-16 and overall a higher percentage of birth-registered females. Of those assessed, 36% (95% CI 27% to 45%) received puberty suppression, 51% (95% CI 40% to 62%) received masculinising or feminising hormones, 68% (95% CI 57% to 77%) received puberty suppression and/or hormones and 16% (95% CI 10% to 24%) received surgery. No study systematically reported information about the full pathway or psychological care received by children/adolescents. Follow-up in many studies was insufficient or unclear. Reasons for discontinuation were rarely provided. CONCLUSIONS: Prospective studies with long-term follow-up reporting information about the full range of pathways are needed to understand what happens to children and adolescents referred to specialist gender services. Information about provision of psychological care is needed considering high rates of psychosocial difficulties in this population.PROSPERO registration number CRD42021289659.

Psychosocial support interventions for children and adolescents experiencing gender dysphoria or incongruence: a systematic review.

BACKGROUND: National and international guidelines recommend that psychosocial support should be a key component of the care offered to children and adolescents experiencing gender dysphoria/incongruence. However, specific approaches or interventions are not recommended. AIM: To identify and summarise evidence on the outcomes of psychosocial support interventions for children and adolescents (age 0-18) experiencing gender dysphoria/incongruence. METHODS: Systematic review and narrative synthesis. Database searches (MEDLINE; EMBASE; CINAHL; PsycINFO; Web of Science) were performed in April 2022, with results assessed independently by two reviewers. Peer-reviewed articles reporting the results of studies measuring outcomes of psychosocial support interventions were included. Quality was assessed using the Mixed Methods Appraisal Tool. RESULTS: Ten studies were included. Half were conducted in the US, with others from Australia, Canada, New Zealand and the UK. Six were pre-post analyses or cohort studies, three were mixed methods, and one was a secondary analysis of intervention data from four trials. Most studies were of low quality. Most analyses of mental health and psychosocial outcomes showed either benefit or no change, with none indicating negative or adverse effects. CONCLUSIONS: The small number of low-quality studies limits conclusions about the effectiveness of psychosocial interventions for children/adolescents experiencing gender dysphoria/incongruence. Clarity on the intervention approach as well as the core outcomes would support the future aggregation of evidence. More robust methodology and reporting is required.

Interventions to suppress puberty in adolescents experiencing gender dysphoria or incongruence: a systematic review.

BACKGROUND: Treatment to suppress or lessen effects of puberty are outlined in clinical guidelines for adolescents experiencing gender dysphoria/incongruence. Robust evidence concerning risks and benefits is lacking and there is a need to aggregate evidence as new studies are published. AIM: To identify and synthesise studies assessing the outcomes of puberty suppression in adolescents experiencing gender dysphoria/incongruence. METHODS: A systematic review and narrative synthesis. Database searches (Medline, Embase, CINAHL, PsycINFO, Web of Science) were performed in April 2022, with results assessed independently by two reviewers. An adapted version of the Newcastle-Ottawa Scale for cohort studies was used to appraise study quality. Only moderate-quality and high-quality studies were synthesised. The Preferred Reporting Items for Systematic Reviews and Meta-Analyses reporting guidelines were used. RESULTS: 11 cohort, 8 cross-sectional and 31 pre-post studies were included (n=50). One cross-sectional study was high quality, 25 studies were moderate quality (including 5 cohort studies) and 24 were low quality. Synthesis of moderate-quality and high-quality studies showed consistent evidence demonstrating efficacy for suppressing puberty. Height increased in multiple studies, although not in line with expected growth. Multiple studies reported reductions in bone density during treatment. Limited and/or inconsistent evidence was found in relation to gender dysphoria, psychological and psychosocial health, body satisfaction, cardiometabolic risk, cognitive development and fertility. CONCLUSIONS: There is a lack of high-quality research assessing puberty suppression in adolescents experiencing gender dysphoria/incongruence. No conclusions can be drawn about the impact on gender dysphoria, mental and psychosocial health or cognitive development. Bone health and height may be compromised during treatment. More recent studies published since April 2022 until January 2024 also support the conclusions of this review. PROSPERO REGISTRATION NUMBER: CRD42021289659.

Clinical guidelines for children and adolescents experiencing gender dysphoria or incongruence: a systematic review of guideline quality (part 1).

BACKGROUND: Increasing numbers of children and adolescents experiencing gender dysphoria/incongruence are being referred to specialist gender services. There are various guidelines outlining approaches to the clinical care of these children and adolescents. AIM: To examine the quality and development of published guidelines or clinical guidance containing recommendations for managing gender dysphoria/incongruence in children and/or adolescents (age 0-18). A separate paper reports the synthesis of guideline recommendations. METHODS: A systematic review and narrative synthesis. Databases (Medline, Embase, CINAHL, PsycINFO, Web of Science) were searched to April 2022 and web-based searches and contact with international experts continued to December 2022, with results assessed independently by two reviewers. The Appraisal of Guidelines for Research and Evaluation tool was used to examine guideline quality. RESULTS: Twenty-three guidelines/clinical guidance publications (1998-2022) were identified (4 international, 3 regional and 16 national). The quality and methods reporting in these varied considerably. Few guidelines systematically reviewed empirical evidence, and links between evidence and recommendations were often unclear. Although most consulted with relevant stakeholders, including 10 which involved service users or user representatives, it was often unclear how this influenced recommendations and only two reported including children/adolescents and/or parents. Guidelines also lacked clarity about implementation. Two international guidelines (World Professional Association for Transgender Health and Endocrine Society) formed the basis for most other guidance, influencing their development and recommendations. CONCLUSIONS: Most clinical guidance for managing children/adolescents experiencing gender dysphoria/incongruence lacks an independent and evidence-based approach and information about how recommendations were developed. This should be considered when using these to inform service development and clinical practice. PROSPERO REGISTRATION NUMBER: CRD42021289659.

Gender services for children and adolescents across the EU-15+ countries: an online survey.

BACKGROUND: Over the last 10-15 years, there has been an increase in the number of children and adolescents referred to gender services, particularly among adolescent birth-registered females. This population shows a higher prevalence of co-occurring mental health difficulties and neurodevelopmental conditions. Some countries have recently restricted access to medical treatments in recognition of the uncertain evidence base. AIM: To understand the current provision of gender services for children and adolescents across the EU-15+ countries that have comparable high-income healthcare systems, to inform service development in the UK. METHODS: An e-survey of paediatric gender services was conducted between September 2022 and April 2023. It covered service structure, care pathways, interventions and data collection. Data were described and compared to identify similarities and differences among participating services. RESULTS: 15 services in eight countries (Australia, Belgium, Denmark, Norway, Northern Ireland, The Netherlands, Spain and Finland) responded. While a multidisciplinary team was present in all services, its composition and organisation varied. Clinical practice was informed by international guidelines, with four countries following their own national guidelines. Differences were observed in referral criteria, care pathways for prepubertal children and those with co-occurring conditions. Eligibility criteria for medical interventions also varied. Psychosocial support and interventions were limited, and outcome data collection was scarce. CONCLUSIONS: This survey revealed both similarities and key variations in the clinical practice of paediatric gender services across eight different countries. The study emphasises the need for service development that both considers the management of co-occurring conditions and embeds routine data collection in practice.

Clinical guidelines for children and adolescents experiencing gender dysphoria or incongruence: a systematic review of recommendations (part 2).

BACKGROUND: Increasing numbers of children and adolescents experiencing gender dysphoria/incongruence are being referred to specialist gender services and there are various published guidelines outlining approaches to clinical care. AIM: To examine the recommendations about the management of children and/or adolescents (age 0-18) experiencing gender dysphoria/incongruence in published guidelines or clinical guidance. A separate paper examines the quality and development of guidelines. METHODS: A systematic review and narrative synthesis. Databases (Medline, Embase, CINAHL, PsycINFO, Web of Science) were searched to April 2022 and web-based searches and contact with international experts continued to December 2022, with results assessed independently by two reviewers. The Appraisal of Guidelines for Research and Evaluation tool was used to examine guideline quality. RESULTS: 23 guidelines/clinical guidance publications (1998-2022) were identified (4 international, 3 regional, 16 national). Guidelines describe a similar care pathway starting with psychosocial care for prepubertal children, puberty suppressants followed by hormones for eligible adolescents and surgical interventions as these adolescents enter adulthood. In general, there is consensus that adolescents should receive a multidisciplinary assessment, although clear guidance about the purpose or approach is lacking. There are differing recommendations about when and on what basis psychological and medical interventions should be offered. There is limited guidance about what psychological care should be provided, about the management of prepubertal children or those with a non-binary gender identity, nor about pathways between specialist gender services and other providers. CONCLUSIONS: Published guidance describes a similar care pathway; however, there is no current consensus about the purpose and process of assessment for children or adolescents with gender dysphoria/incongruence, or about when psychological or hormonal interventions should be offered and on what basis.

Masculinising and feminising hormone interventions for adolescents experiencing gender dysphoria or incongruence: a systematic review.

BACKGROUND: Clinical guidelines outline the use of hormones for masculinisation/feminisation in adolescents experiencing gender dysphoria or incongruence. Robust evidence concerning risks and benefits is lacking. There is a need to aggregate evidence as research becomes available. AIM: Identify and synthesise studies assessing the outcomes of hormones for masculinisation/feminisation in adolescents experiencing gender dysphoria/incongruence. METHODS: Systematic review and narrative synthesis. Database searches (MEDLINE, Embase, CINAHL, PsycINFO, Web of Science) were performed in April 2022, with results assessed independently by two reviewers. An adapted version of the Newcastle-Ottawa Scale for Cohort Studies was used to assess study quality. Moderate- and high-quality studies were synthesised. RESULTS: 12 cohort, 9 cross-sectional and 32 pre-post studies were included (n=53). One cohort study was high-quality. Other studies were moderate (n=33) and low-quality (n=19). Synthesis of high and moderate-quality studies showed consistent evidence demonstrating induction of puberty, although with varying feminising/masculinising effects. There was limited evidence regarding gender dysphoria, body satisfaction, psychosocial and cognitive outcomes, and fertility. Evidence from mainly pre-post studies with 12-month follow-up showed improvements in psychological outcomes. Inconsistent results were observed for height/growth, bone health and cardiometabolic effects. Most studies included adolescents who received puberty suppression, making it difficult to determine the effects of hormones alone. CONCLUSIONS: There is a lack of high-quality research assessing the use of hormones in adolescents experiencing gender dysphoria/incongruence. Moderate-quality evidence suggests mental health may be improved during treatment, but robust study is still required. For other outcomes, no conclusions can be drawn. More recent studies published since April 2022 until January 2024 also support the conclusions of this review.PROSPERO registration number: CRD42021289659.

Impact of social transition in relation to gender for children and adolescents: a systematic review.

BACKGROUND: Increasing numbers of children and adolescents experiencing gender dysphoria or incongruence are being referred to specialist gender services. Historically, social transitioning prior to assessment was rare but it is becoming more common. AIM: To identify and synthesise studies assessing the outcomes of social transition for children and adolescents (under 18) experiencing gender dysphoria/incongruence. METHODS: A systematic review and narrative sythesis. Database searches (Medline, Embase, CINAHL, PsycINFO, Web of Science) were perfomed in April 2022. Studies reporting any outcome of social transition (full or partial) for children and adolescents experiencing gender dysphoria/incongruence were included. An adapted version of the Newcastle-Ottawa Scale for cohort studies was used to appraise study quality. RESULTS: Eleven studies were included (children (n=8) and adolescents (n=3)) and most were of low quality. The majority were from the US, featured community samples and cross-sectional analyses. Different comparator groups were used, and outcomes related to mental health and gender identity reported. Overall studies consistently reported no difference in mental health outcomes for children who socially transitioned across all comparators. Studies found mixed evidence for adolescents who socially transitioned. CONCLUSIONS: It is difficult to assess the impact of social transition on children/adolescents due to the small volume and low quality of research in this area. Importantly, there are no prospective longitudinal studies with appropriate comparator groups assessing the impact of social transition on mental health or gender-related outcomes for children/adolescents. Professionals working in the area of gender identity and those seeking support should be aware of the absence of robust evidence of the benefits or harms of social transition for children and adolescents.

Seeing the child in context: Supporting gender diverse children and their families in multiple ways - An introduction to this special edition.

This Special Issue of Clinical Child Psychology and Psychiatry includes a group of papers that originated in the work of the Gender Identity Development Service (GIDS), which is the nationally designated National Health Service (NHS) in the United Kingdom to work with children and adolescents experiencing significant concern and distress about their gender. This short introduction to those papers aims to set the context and explain why certain areas have been given a focus.

Understanding more about how young people make sense of their siblings changing gender identity: How this might affect their relationships with their gender-diverse siblings and their experiences.

The gender roles and identity of siblings have been found to be an important factor in the nature and quality of sibling relationships. With an increasing number of young people identifying as gender-diverse or transgender, this research aimed to develop a greater understanding of how young people make sense of their siblings' gender diversity. Semi-structured interviews explored the experiences of eight sibling participants (aged 11-25 years) who have a sibling identifying as gender-diverse. Five overarching themes emerged from the thematic analysis of their transcribed interviews. These themes encapsulated commonalities and nuances within the sibling participants' experiences and revealed a process of adjustment. Developing an increased understanding of transgender issues appeared to enable young people to embrace supportive roles, and as a consequence, they reported that their relationships with their gender-diverse siblings were enhanced. However, the sibling participants' increased understanding of transgender issues also generated significant fears and concerns about their siblings' well-being and their sibling relationships. From understanding more about these eight young people's experiences, suggestions are given for how specialist services might best support siblings of gender-diverse young people along their processes of adjustment.
