RESUMEN
Over the last decade, there has been a sharp increase in young people seeking medical treatment for gender dysphoria/gender incongruence (GD/GI). The aims of this study were to calculate yearly population-adjusted numbers of children and adolescents referred to the Norwegian National Center for Gender Incongruence (NCGI) at Oslo University Hospital (OUS) from 2000 to 2022; to describe the demographic characteristics and prevalence of psychiatric diagnoses, self-harm and suicide attempts among the referred from 2000 to 2020; and to investigate time trends. The study used data from the Gender Incongruence Registry for Children and Adolescents (GIRCA) in Norway. All persons under 18 years (n = 1258) referred to the NCGI between 2000 and 2020 were included: 68.4% assigned female gender at birth (AFAB) and 31.6% assigned male gender at birth (AMAB). We found a sharp increase in referrals to the NCGI favouring AFAB over AMAB. Nearly two in three (64.5%) had one or more registered psychiatric diagnoses. Self-harm was registered among 35.5%, and 12.7% had attempted suicide. Registered psychiatric diagnoses were significantly (p ≤ 0.001) more prevalent among AFAB (67.8%) than AMAB (57.4%). The number of registered diagnoses per person decreased significantly over time, with an average reduction of 0.02 diagnoses per person per year. Although there was a downward time trend in registered diagnoses per person, the total mental health burden among children and adolescents with GI emphasizes the need for a holistic approach.
RESUMEN
PURPOSE: Several studies have reported on the intersection of autism and gender incongruence (GI) in clinical populations. This study aims to investigate autistic characteristics and registered autism spectrum diagnoses (ASD) in a clinical cohort of 83 adolescents referred to the National Gender Team for Children and Adolescents in Norway during 2020. METHODS: Parents completed the Social Responsiveness Scale (SRS). Background information and registered psychiatric diagnoses were extracted from patient files. RESULTS: The results showed that 25% of the participants scored within the clinical range on the SRS: 27.4% of adolescents who were assigned female at birth (AFAB) and 19.0% of adolescents who were assigned male at birth (AMAB). AFAB had significantly higher scores on SRS Total Scale and the Social Motivation and Autistic Mannerisms subscales compared to the female norm group. AMAB had higher scores on the Social Motivation subscale and lower scores on the Social Awareness subscale, compared to the male norm population. Information from patient files revealed that 67.5% had one or more registered psychiatric diagnosis. 9.6% had received an ASD diagnosis, all AFAB. 18.1% had received an attention deficit hyperactivity disorder (ADHD) diagnosis. The most common psychiatric diagnoses were depression (25.3%) and anxiety disorders (18.1%). Further, 44.6% had a history of self-harm, and 15.7% had a history of a suicide attempt. CONCLUSION: The results showed an overrepresentation of ASD diagnoses and autistic characteristics measured by SRS for AFAB. There was an overrepresentation of psychiatric diagnoses for both the AFAB and the AMAB group in this study sample. Implications for treatment and future research are discussed.
