Background: Anemia and deficiency of vitamin D (VDD) are frequently seen in seniors and an association is suspected. Approximately one third of the German population is affected by VDD, with a rising prevalence among seniors., Aim: To analyze the association between anemia and VDD among German seniors aged ≥ 60 years., Methods: Retrospective cross-sectional data analysis (n = 4008) in a nationwide working laboratory medical center (January-December 2019). Study parameters included amongst others: hemoglobin (Hb), calcifediol (25D) and calcitriol (1.25D), glomerular filtration rate (GFR) to assess the kidney disease outcomes quality initiative (KDOQI) state. The inclusion criteria were age ≥ 60 years, normal C‑reactive protein (CRP) and leucocyte levels., Results: The 25D was estimated in 4008 patients and 1.25D only in 411 patients. Mean age 75 years (± 8.61 years; 60-99 years) with 30.6% males; mean GFR 62 ml/min/1.73 m 3 (± 22.74); 20% of patients were anemic, 35% were deficient for 25D (< 50 nmol/l), with men > women (p = 0.014). Linear regression analysis revealed a significant effect of 25D values < 30 nmol/l on hemoglobin in males of KDOQI I-III and females of KDOQI I-IV (R2 = 0.052; p = 0.005; and R2 = 0.124; p < 0.001, respectively). For 1.25D a weak but significant effect on hemoglobin independent of KDOQI was only seen in women (R2 = 0.200; p = 0.005)., Conclusion: In this cohort deficiency of 25D and 1.25D was significantly associated with hemoglobin independent of renal function only in women but not in men., (© 2024.

Adolescents spend a critical amount of their free time on the Internet and social media. Transgender and gender-diverse (TGD) adolescents, who report elevated rates of mental health issues, especially internalizing problems, have both positive and negative online social experiences (e.g., support and cyberbullying). This can have both beneficial and/or harmful effects on their mental health. Given the lack of research, the present study examined TGD adolescents' online (social) experiences and the association of positive and negative online social experiences with internalizing problems. The sample consisted of n = 165 TGD adolescents (11-18 years) diagnosed with gender dysphoria who attended a Gender Identity Service for children and adolescents (Hamburg GIS) in Germany between January 2020 and December 2022 during the COVID-19 pandemic. Positive (use of online support networks) and negative online social experiences (cyberbullying or other adverse online interactions) were assessed using study-specific items and internalizing problems using the Youth Self-Report. Frequencies of various online (social) experiences were analyzed, and a multiple linear regression analysis was performed to test their association with internalizing problems. In total, 42% of participants reported positive online social experiences (use of online support networks) and 51% of participants reported negative online social experiences (cyberbullying or other adverse online interactions). There was no significant association between negative online social experiences and internalizing problems but between positive online social experiences and more internalizing problems (adjusted R 2  = .01). TGD adolescents may seek online support, especially when struggling with mental health problems. Therefore, it is crucial to support youth navigating these online spaces more safely and positively and to empower them to buffer against potentially harmful experiences. Furthermore, strengthening offline relations with peers and family members is pivotal, given their importance for TGD adolescents' mental health., Competing Interests: Declarations Competing interests The authors declare that they have no competing interests.

Importance: Major depressive disorder is one of the most common mental disorders among adolescents, entailing severe, long-term psychosocial impairment and a high risk of chronicity. In view of the large number of patients requiring treatment, along with insufficient treatment responses with small effect sizes, innovative adjunctive treatment strategies are urgently needed., Objective: To investigate whether the effect of adolescent psychiatric inpatient treatment as usual for major depressive disorder can be enhanced by simultaneous use of morning bright light therapy., Design, Setting, and Participants: This was a double-blind, placebo-controlled randomized parallel-group trial with enrollment between March 2018 and November 2020 and follow-up completed in May 2021. The study took place among inpatients at 4 university hospitals for child and adolescent psychiatry across Germany. Of 248 eligible youth aged 12 to 18 years fulfilling ICD-10 criteria for major depressive disorder, 227 were randomized to bright light therapy (n = 116) or placebo red light (n = 111); 151 participants completed the study., Interventions: Up to 20 sessions of either morning bright light therapy with an intensity of 10 000 lux or placebo red light (100 lux) in addition to multimodal inpatient treatment as usual over 4 weeks., Main Outcomes and Measures: The primary outcome was the change in Beck Depression Inventory-II (BDI-II) score from baseline to posttreatment in the intention-to-treat sample., Results: Among the 224 patients included in the intention-to-treat analyses (192 girls and 32 boys; mean [SD] age, 15.5 [1.4] years), the mean (SD) BDI-II score at baseline was 37.3 (8.7). BDI-II scores were significantly reduced after 4 weeks (postassessment) by a mean of -7.5 (95% CI, -9.0 to -6.0; Hedges g = 0.71). Bright light therapy had no impact on this change (no significant group × time effect). Loss to follow-up was 31% (n = 69) at 16 weeks and 49% (n = 110) at 28 weeks. There were 10 serious adverse events throughout the whole trial, which were not considered related to study treatment., Conclusions and Relevance: The findings in this study did not indicate superiority of bright light therapy over placebo red light therapy in a large sample of adolescent inpatients with moderate or severe major depressive disorder. Both groups benefited equally from treatment as usual, showing relevant symptom reduction., Trial Registration: German Clinical Trials Register: DRKS00013188.

Background: Prostate-related quality of life can be assessed with a variety of different questionnaires. The 50-item Expanded Prostate Cancer Index Composite (EPIC) and the International Prostate Symptom Score (IPSS) are two widely used options. The goal of this study was, therefore, to develop and validate a model that is able to convert between the EPIC and the IPSS to enable comparisons across different studies., Methods: Three hundred forty-seven consecutive patients who had previously received radiotherapy and surgery for prostate cancer at two institutions in Switzerland and Germany were contacted via mail and instructed to complete both questionnaires. The Swiss cohort was used to train and internally validate different machine learning models using fourfold cross-validation. The German cohort was used for external validation., Results: Converting between the EPIC Urinary Irritative/Obstructive subscale and the IPSS using linear regressions resulted in mean absolute errors (MAEs) of 3.88 and 6.12, which is below the respective previously published minimal important differences (MIDs) of 5.2 and 10 points. Converting between the EPIC Urinary Summary and the IPSS was less accurate with MAEs of 5.13 and 10.45, similar to the MIDs. More complex model architectures did not result in improved performance in this study. The study was limited to the German versions of the respective questionnaires., Conclusions: Linear regressions can be used to convert between the IPSS and the EPIC Urinary subscales. While the equations obtained in this study can be used to compare results across clinical trials, they should not be used to inform clinical decision-making in individual patients., Trial Registration: This study was retrospectively registered on clinicaltrials.gov on January 14th, 2022, under the registration number NCT05192876., (© 2024.

Clinical research on transgender and gender-nonconforming (TGNC) adolescents has focused on binary individuals or often not differentiated among gender identities. Recent studies suggest that a considerable proportion of TGNC adolescents identify as non-binary and that these youth report more internalizing problems as well as different transition-related medical treatment wishes than binary adolescents. However, the results are inconclusive, and data for the German-speaking area are lacking. Therefore, the present study aimed to assess the percentage of binary and non-binary gender identities in a German sample of clinically referred TGNC adolescents and examine associations of gender identity with internalizing problems and transition-related medical treatment wishes. The sample consisted of 369 adolescents (11-18 years, M age  = 15.43; 305 birth-assigned female, 64 birth-assigned male) who attended the Hamburg Gender Identity Service for children and adolescents (Hamburg GIS) between 2013 and 2019. Gender identity and treatment wishes were assessed using study-specific items and internalizing problems using the Youth Self-Report. In total, 90% (n = 332) of the sample identified as binary and 10% (n = 37) as non-binary. Having a non-binary gender identity was significantly associated with more internalizing problems and with wishing for no transition-related medical treatment or only puberty-suppressing hormones. The results underscore that non-binary adolescents represent a specifically vulnerable subgroup within TGNC adolescents with unique mental health needs and treatment wishes. Future research should differentiate among various gender identities. In clinical practice, it is crucial to create an inclusive space for non-binary youth and provide mental health care if needed., (© 2023. The Author(s).)

Objective: The review systematically reviews the literature on co-occurring gender dysphoria/gender variance and autism spectrum disorder among children and adolescents., Methods: A systematic literature search was conducted for the years 1946 to December 2018., Results: 144 publications could be identified in the literature search. Out of these, 22 publications met the inclusion criteria for the systematic review. 4.7 to 13.3 % of the children and adolescents with primarily diagnosed gender dysphoria/variance examined in the studies also had an autism diagnosis. In samples of children and adolescents with primarily diagnosed autism gender variance was overrepresented with a prevalence of 4 to 6.5 %., Conclusion: The results of the systematic review point towards an overrepresentation of co-occurring gender dysphoria/variance and autism spectrum disorder. Methodological and clinical implications are discussed., Competing Interests: Die Autorinnen/Autoren geben an, dass kein Interessenkonflikt besteht., (© Georg Thieme Verlag KG Stuttgart · New York.)

Transgender in adolescence is currently a widely discussed topic, additionally reflected by an increasing prevalence in clinical practice. The present review of the available literature on transgender, trans* , gender dysphoria or gender incongruence in youth reports results on the long-term results of medical interventions for the psychological well-being, prevalence, referral rates and sex ratio, developmental pathways, current developments and the role of the social environment.

Background: There is growing interest to integrate palliative care and its structures into the care of neurological patients. However, in Germany there is no comprehensive assessment tool capturing the symptoms of patients with advanced neurological diseases., Aim: To validate a newly developed palliative care measurement tool based on an extension of the validated core documentation system Hospice and Palliative Care Evaluation considering additional neurological issues (HOPE+)., Design: Prospective, observational study using HOPE+ and as external criteria, the Eastern Cooperative Oncology Group (ECOG) performance status and the 12 months "surprise" question (12-SQ) in a neurological population, and assessment for its construct validity and diagnostic accuracy., Setting/participants: All newly admitted patients to the Department of Neurorehabilitation, Dr. Becker Rhein-Sieg-Clinic aged 18-100 years (#DRKS00010947)., Results: Data from 263 patients (63 ± 14 years of age) were analyzed. HOPE+ revealed a moderately correlated six-factor structure ( r  = -0.543-0.525). Correlation analysis to evaluate discriminant validity using ECOG as external criterion was high ( r s(261) = 0.724, p  < 0.001) and confirmed for severely affected patients by adding the 12-SQ ("No"-group: 48.00 ± 14.92 vs "Yes"-group: 18.67 ± 7.57, p  < 0.009). Operating characteristics show satisfactory diagnostic accuracy (area under the curve: 0.746 ± 0.049, 95% confidence interval = 0.650-0.842)., Conclusion: HOPE+ demonstrates promising psychometric properties. It helps to assess palliative care issues of patients in neurological settings and, in combination with the 12-SQ, conceivably conditions when to initiate the palliative care approach in a population underrepresented in palliative care structures so far.

Introduction: Gender Dysphoria (GD) refers to a distress resulting from an incongruence between the individual's sex characteristics and the experience of their gender (Gender Incongruence, GI). The interaction between medical treatment of GI/GD and social support in the long-term has not been investigated sufficiently so far., Material & Methods: Using an online questionnaire, the present study investigated n=117 individuals with GI/GD assigned male and n=52 assigned female at birth that had been referred to one of the specialized clinics of the European Network for the Investigation of Gender Incongruence (ENIGI) in Belgium, the Netherlands, and Germany.They filled out a questionnaire at 2 time points within a follow-up time of 4 to 6 years after clinical entry (between 2007 and 2009). Two hierarchical regression analyses explored the effects of the sex assigned at birth, the treatment progress and social support on mental distress and satisfaction with life at follow-up in the sample., Results: A female sex assigned at birth and higher degrees of social support significantly predicted the reduction in mental distress at follow-up. An advanced stage of the individual treatment and higher social support significantly predicted an increase in overall satisfaction with life., Discussion: The results illustrate the importance of social support with regard to the outcome of medical treatment of GI/GD., Competing Interests: Die Autoren geben an, dass kein Interessenkonflikt besteht., (© Georg Thieme Verlag KG Stuttgart · New York.)

Background: Sedentary behaviour is a health risk factor independent of physical activity. Interventions that aim to reduce sitting at the workplace are particularly important as office workers spend a large proportion of their working hours sitting. This systematic review examines whether these interventions (SB or PA interventions during work time) reduce sitting time among office workers and which variables moderate intervention effects., Methods: A systematic literature search was conducted from April to May 2016 in the following databases: PubMed, PsycINFO and SPORTDiscus. In total, we identified 17 studies that assessed the time spent in sedentary behaviour at the office workplace. To summarize the study results, we applied a best-evidence synthesis. Additionally, we evaluated potential moderators, such as intervention strategies., Results: Multi-component interventions and sit-stand workstations were most promising sedentary reduction interventions. The analysis of moderators highlighted that the proportion of positive intervention effects was higher in interventions based on the strategies "environmental restructuring", "adding objects to the environment" and "instructions on how to carry out the behaviour". Furthermore, interventions focusing on sedentary behaviour only and studies using objective measurement tools showed more often positive interventions effects., Conclusions: There are many promising interventions to reduce sitting time at the office workplace. However, there is insufficient evidence if the effects of these interventions are sustainable in the long term. Moreover, the considerable heterogeneity of included studies limits the validity of our findings. Future intervention studies should build on a theoretical planning approach and use subjective as well as objective evaluation measures., Competing Interests: Die Autoren geben an, dass kein Interessenkonflikt besteht., (© Georg Thieme Verlag KG Stuttgart · New York.)

Background: Peripheral arterial disease (PAD) is one of the major manifestations of general atherosclerosis and strongly associated with increased cardiovascular morbidity and mortality. Because only few epidemiologic studies are available concerning the prevalence of PAD in inhabitants ≥ 80 years of age, we screened inhabitants of nursing care homes in Germany for PAD and cardiovascular diseases and to assess the one year mortality., Patients and Methods: We conducted a prospective cohort study, screening inhabitants of 42 nursing homes for PAD. Demographic data, comorbidities, cardiovascular risk factors and daily medication were collected. PAD was defined as ankle-brachial index < 0.9. During a follow up period of one year, cardio- and cerebrovascular events and mortality were recorded, as well as the rate of falls and major amputation., Results: 1,329 probands (391 men, 938 women) > 60 years were eligible for further analysis. The mean age was 84.1 years (range 61-107 years) and the prevalence of PAD was 31.5 % . Media sclerosis was found in up to 17 %, and an existing diagnosis of PAD (in case of pathological ABI) and undertreatment was common. Probands with PAD were less likely to be treated according to guideline recommendations (antiplatelet therapy, beta blockers, statins) than probands with coronary artery disease (CAD). The overall one-year mortality was 19.8 % (n = 236), significantly higher than for a gender and age matched German population (p < 0.001)., Conclusions: The current study shows a high prevalence of PAD in German nursing care homes. The one year mortality was not significantly different between probands with PAD and those with severe PAD (defined as an ABI of ≤ 0.5), whereas a media sclerosis was associated with an increased risk in probands with CAD in comparison to those without. Use of anti-diabetic agents and aspirin in monotherapy was associated with a reduced one-year mortality risk.

Persistent feelings of gender dysphoria (GD) are accompanied by distress and body dissatisfaction in most clinically referred adolescents and adults. Transition-related medical interventions (e.g., puberty suppression, hormones, or surgery) may alleviate body dissatisfaction. The aim of the present cross-sectional study was to compare multidimensional body image across clinically referred adolescents and adults undergoing different transition-related medical interventions. Two clinical samples of adolescents (n = 82) and adults (n = 120) referred to specialized departments of four different transgender health services in Germany participated in the study. In total, 202 individuals from the female-to-male (FtM individuals) and male-to-female (MtF individuals) spectrum aged 14-74 years were included at different stages of their transition. Four scales assessing multidimensional aspects of body image (measured by the Body Image Assessment Questionnaire, FBeK) were compared across three groups: sample, gender, and medical interventions (while controlling for age and treatment duration). The results indicated less favorable body image scores compared with the norm in both adolescents and adults with GD. Individuals who had undergone transition-related medical interventions presented a significantly better body image on two of the four scales. Differences according to gender and age were also present. These findings suggest that medical interventions, especially gender-affirming hormones and surgery, are generally beneficial to the body image in individuals with GD. However, not all of the less favorable outcomes in multidimensional body image were positively influenced by the treatment conditions and may thus benefit from additional integrative counseling before and during transition.

Background: Acute kidney injury is a frequent complication after cardiac surgery and is associated with adverse outcomes. Although short-term calorie restriction (CR) has proven protective in rodent models of acute kidney injury, similar effects have not yet been demonstrated in humans., Methods and Results: CR&#95;KCH (Effect of a Preoperative Calorie Restriction on Renal Function After Cardiac Surgery) is a randomized controlled trial in patients scheduled for cardiac surgery. Patients were randomly assigned to receive either a formula diet containing 60% of the daily energy requirement (CR group) or ad libitum food (control group) for 7 days before surgery. In total, 82 patients were enrolled between April 16, 2012, and February 5, 2015. There was no between-group difference in the primary end point of median serum creatinine increment after 24 hours (control group: 0.0 mg/dL [-0.1 - (+0.2) mg/dL]; CR group: 0.0 mg/dL [-0.2 - (+0.2) mg/dL]; P =0.39). CR prevented a rise in median creatinine at 48 hours (control group: +0.1 mg/dL [0.0 - 0.3 mg/dL]; CR group: -0.1 mg/dL [-0.2 - (+0.1) mg/dL]; P =0.03), with most pronounced effects observed in male patients and patients with a body mass index >25. This benefit persisted until discharge: Median creatinine decreased by 0.1 mg/dL (-0.2 - 0.0 mg/dL) in the CR group, whereas it increased by 0.1 mg/dL (0.0 - 0.3 mg/dL; P =0.0006) in the control group. Incidence of acute kidney injury was reduced by 5.8% (41.7% in the CR group compared with 47.5% in the control group). Safety-related events did not differ between groups., Conclusions: Despite disappointing results with respect to creatinine rise within the first 24 hours, the benefits observed at later time points and the subgroup analyses suggest the protective potential of short-term CR in patients at risk for acute kidney injury, warranting further investigation., Clinical Trial Registration: URL: http://www.clinicaltrials.gov.

Background: Anemia and hypoalbuminemia (HA) are acknowledged independent risk factors for morbidity and mortality in geriatric patients and are associated with nutritional status and frailty. Data exist regarding the association between albumin and frailty, anemia and frailty as well as frailty and nutritional status; however, there is a lack of information on the association between HA, anemia and nutritional status in older people., Patients and Methods: This study retrospectively analyzed 626 patients admitted to a German geriatrics department (average age 81.1 years, 68.2% female and 31.8% male) for anemia and HA. Data from the comprehensive geriatric assessment (CGA) and from the mini-nutritional assessment (MNA) were available in all patients., Results: Patients with anemia suffered significantly more often from HA (p<0.001) than patients without anemia, with an odds ratio (OR) of 1.99 (95% confidence interval CI: 1.2-3.2) and of 5.41 (CI 95%: 2.3-12.6) in patients at risk for malnutrition and in malnourished patients, respectively. A moderately significant association was seen between hemoglobin (Hb) and albumin values (Pearson's correlation r=0.330; p<0.001) as well as between albumin values and the Barthel index (Spearman's correlation r=0.210; p<0.001)., Conclusion: Anemia appears to be a risk factor for HA in inpatients with malnutrition and the observed association between albumin and Hb warrants further research. Geriatric inpatients with anemia should be evaluated in terms of the presence of malnutrition risk and HA.

Innovative developments in the pharmacotherapy of juvenile idiopathic arthritis and especially biologics allow the formulation of new therapeutic targets, such as the rapid induction of remission with shortening of the period of active disease and therefore preventing damage and disability. These new therapies also represent a challenge to the monitoring of drug safety, the pharmacovigilance. For this purpose the Society for Paediatric and Adolescent Rheumatology has set up an early register to record achievements in treatment improvement and in addition to independently assess information on drug safety, acute tolerance and long-term safety.

The purpose of this cross-sectional prospective study was to determine the prevalence of anemia among elderly hospitalized patients in Germany and to investigate its association with multidimensional loss of function (MLF). One hundred participants aged 70 years or older from two distinct wards (50 each from an emergency department and a medical ward, respectively) underwent a comprehensive geriatric assessment (CGA) consisting of the following six tools: Barthel Index, mini-mental state examination, clock-drawing test, timed up and go test, Esslinger transfer scale, and Daniels test. MLF as an aggregated outcome was diagnosed when three or more tests of the CGA showed an abnormal result. Anemia was defined according to WHO criteria as a hemoglobin (Hb) concentration of <13 g/dL for men and <12 g/dL for women. The prevalence of anemia was 60 %. Overall, 61 % of patients presented with three or more abnormal results in the six tests of the CGA and, thus, with MLF. Using logistic regression, we found a significant association of both anemia and low Hb concentrations with abnormal outcomes in five tests of the CGA and, therefore, with domain-specific deficits like mobility limitations, impaired cognition, and dysphagia. Furthermore, being anemic increased the odds of featuring MLF more than fourfold. This significant relationship persisted after adjustment for various major comorbidities. Both anemia and geriatric conditions are common in the hospitalized elderly. Given the association of anemia with MLF, Hb level might serve as a useful geriatric screening marker to identify frail older people at risk for adverse outcomes.

Objective: The aim of this study was to determine demographic, clinical, articular and laboratory variables predicting etanercept response in JIA., Methods: A total of 863 patients registered in the BIKER registry were included. Predictors of response for ACR paediatric criteria (PedACR) 30, 70 and 90 were analysed by bivariate analysis and logistic regression., Results: After 6 months, 81.9% of the included patients fulfilled the PedACR30, 55.2% the PedACR70 and 31.3% the PedACR90 criteria. In bivariate analyses, factors positively correlated with a PedACR70/90 response were extended oligoarthritis JIA category, lower age at the start of treatment, shorter disease duration until treatment start, no concomitant use of corticosteroids, duration of morning stiffness, parents' global assessment of overall well-being, lower Childhood Health Assessment Questionnaire (CHAQ) and higher ESR and ANA. Correlation between the JIA category systemic arthritis and response was significantly negative. Predictive factors for PedACR70 in multivariate logistic regression analysis were CHAQ [odds ratio (OR) = 0.70], ESR (OR = 1.02) and concomitant treatment with corticosteroids (OR = 0.68). Age at treatment start (OR = 0.94) and the systemic arthritis JIA category (OR = 0.28) were predictive for a PedACR70. We found no sufficiently distinctive models for PedACR30 or 90., Conclusion: Parameters predicting a high-grade response to a 6-month course of etanercept were identifiable and included age at treatment start, disease duration before treatment, JIA category other than systemic arthritis, CHAQ, parents' global assessment and concomitant corticosteroids., (© The Author 2014.

Objective: The aim of this study was to define improvement thresholds for the Juvenile Arthritis Disease Activity Score (JADAS)., Methods: Physicians' and parents' judgements on treatment efficacy, the ACR paediatric response measure (PedACR) and JADAS were extracted from BIKER. Patients were categorized by baseline classes in the 10-joint JADAS (JADAS10) as low (5 to <15), moderate (15 to <25) and high (25 to ≤40). Cut-offs for defining improvement following treatment with biologics or MTX were chosen by calculating the interquartile ranges (IQRs) of the judgement groups and considering the accuracy, sensitivity and specificity of the resulting model. Differences in the change of JADAS10 by JIA category were also analysed by analysis of variance (ANOVA). Sensitivity, specificity and accuracy were calculated., Results: A total of 1315 treatment courses were analysed. The ANOVA of the JIA categories showed no significant differences of the mean JADAS10 in all baseline classes and IQRs also showed good overall limits. Therefore all JIA categories were combined for a collective cut-off. Analysis by baseline class revealed clear cut-off points. Improvement could be defined by the minimal decrease in the JADAS10 in baseline class low by 4 (41%), moderate by 10 (53%) and high by 17 (57%). The model shows values for accuracy from 75.6 to 85.5% and comparable values for sensitivity and specificity., Conclusion: Improvement after 3 months can be defined efficiently by the decrease of the JADAS10, depending on the baseline JADAS10 score, which specifies low, moderate or high disease activity. Our model demonstrates clear cut-off values. The JADAS10 may be used in addition to ACR criteria in clinical trials. Also, since the JADAS10 can easily be calculated at each patient visit, it also can be used for clinical decisions., (© The Author 2014.

Given the increasing demand for counselling in gender dysphoria in childhood in Germany, there is a definite need for empirical data on characteristics and developmental trajectories of this clinical group. This study aimed to provide a first overview by assessing demographic characteristics and developmental trajectories of a group of gender variant boys and girls referred to the specialised Gender Identity Clinic in Hamburg. Data were extracted from medical charts, transcribed and analysed using qualitative content analysis methods. Categories were set up by inductive-deductive reasoning based on the patients' parents' and clinicians' information in the files. Between 2006 and 2010, 45 gender variant children and adolescents were seen by clinicians; 88.9% (n = 40) of these were diagnosed with gender identity disorder (ICD-10). Within this group, the referral rates for girls were higher than for boys (1:1.5). Gender dysphoric girls were on average older than the boys and a higher percentage of girls was referred to the clinic at the beginning of adolescence (> 12 years of age). At the same time, more girls reported an early onset age. More girls made statements about their (same-sex) sexual orientation during adolescence and wishes for gender confirming medical interventions. More girls than boys revealed self-mutilation in the past or present as well as suicidal thoughts and/or attempts. Results indicate that the presentation of clinically referred gender dysphoric girls differs from the characteristics boys present in Germany; especially with respect to the most salient age differences. Therefore, these two groups require different awareness and individual treatment approaches.
