Systematic review and meta-analysis of prevalence studies in transsexualism.

BACKGROUND Over the last 50 years, several studies have provided estimates of the prevalence of transsexualism. The variation in reported prevalence is considerable and may be explained by factors such as the methodology and diagnostic classification used and the year and country in which the studies took place. Taking these into consideration, this study aimed to critically and systematically review the available literature measuring the prevalence of transsexualism as well as performing a meta-analysis using the available data. METHODS Databases were systematically searched and 1473 possible studies were identified. After initial scrutiny of the article titles and removal of those not relevant, 250 studies were selected for further appraisal. Of these, 211 were excluded after reading the abstracts and a further 18 after reading the full article. This resulted in 21 studies on which to perform a systematic review, with only 12 having sufficient data for meta-analysis. The primary data of the epidemiological studies were extracted as raw numbers. An aggregate effect size, weighted by sample size, was computed to provide an overall effect size across the studies. Risk ratios and 95% confidence intervals (CIs) were calculated. The relative weighted contribution of each study was also assessed. RESULTS The overall meta-analytical prevalence for transsexualism was 4.6 in 100,000 individuals; 6.8 for trans women and 2.6 for trans men. Time analysis found an increase in reported prevalence over the last 50 years. CONCLUSIONS The overall prevalence of transsexualism reported in the literature is increasing. However, it is still very low and is mainly based on individuals attending clinical services and so does not provide an overall picture of prevalence in the general population. However, this study should be considered as a starting point and the field would benefit from more rigorous epidemiological studies acknowledging current changes in the classification system and including different locations worldwide.

Mental health and gender dysphoria: A review of the literature

Abstract Studies investigating the prevalence of psychiatric disorders among trans individuals have identified elevated rates of psychopathology. Research has also provided conflicting psychiatric outcomes following gender-confirming medical interventions. This review identifies 38 cross-sectional and longitudinal studies describing prevalence rates of psychiatric disorders and psychiatric outcomes, pre- and post-gender-confirming medical interventions, for people with gender dysphoria. It indicates that, although the levels of psychopathology and psychiatric disorders in trans people attending services at the time of assessment are higher than in the cis population, they do improve following gender-confirming medical intervention, in many cases reaching normative values. The main Axis I psychiatric disorders were found to be depression and anxiety disorder. Other major psychiatric disorders, such as schizophrenia and bipolar disorder, were rare and were no more prevalent than in the general population. There was conflicting evidence regarding gender differences: some studies found higher psychopathology in trans women, while others found no differences between gender groups. Although many studies were methodologically weak, and included people at different stages of transition within the same cohort of patients, overall this review indicates that trans people attending transgender health-care services appear to have a higher risk of psychiatric morbidity (that improves following treatment), and thus confirms the vulnerability of this population.

A multi-centre cohort study of short term outcomes of hospital treatment for anorexia nervosa in the UK

BackgroundIndividual, family and service level characteristics and outcomes are described for adult and adolescent patients receiving specialist inpatient or day patient treatment for anorexia nervosa (AN). Potential predictors of treatment outcome are explored.MethodAdmission and discharge data were collected from patients admitted at 14 UK hospital treatment units for AN over a period of three years (adult units N = 12; adolescent N = 2) (patients N = 177).ResultsOne hundred and seventy-seven patients with a severe and enduring illness with wide functional impairment took part in the study. Following inpatient care, physical improvement was moderate/good with a large increase in BMI, although most patients continued to have a clinical level of eating disorder symptoms at discharge. The potentially modifiable predictors of outcome included confidence to change, social functioning and carer expressed emotion and control.ConclusionsOverall, the response to inpatient treatment was modest particularly in the group with a severe enduring form of illness. Adolescents had a better response. Although inpatient treatment produces an improvement in physical health there was less improvement in other eating disorder and mood symptoms. As predicted by the carer interpersonal maintenance model, carer behaviour may influence the response to inpatient care, as may improved social functioning and confidence to change.

Social Support and Psychological Well-Being in Gender Dysphoria: A Comparison of Patients With Matched Controls

INTRODUCTION There is a paucity of research in the area of social support and psychological well-being among people with gender dysphoria. AIMS The present study aimed to investigate levels of social support among individuals with gender dysphoria compared with a matched control group. It also aimed to examine the relationship between social support and psychological well-being. METHODS Participants were 103 individuals diagnosed with gender dysphoria (according to ICD-10 criteria) attending a national gender identity clinic and an age- and gender-matched nonclinical control group recruited via social networking websites. MAIN OUTCOME MEASURES All participants completed measures of social support (Multidimensional Scale of Perceived Social Support, MSPSS), psychopathology (Symptom Checklist 90 Revised, SCL), quality of life (Short Form 36 version 2, SF), and life satisfaction (Personal Wellbeing Index, PWI). RESULTS Trans women reported significantly lower MSPSS total and MSPSS family scores compared with control women, although these differences in levels of social support were no longer significant when SCL depression was controlled for. No significant differences were found between trans men and any other group. MSPSS scores did not significantly predict SCL subscales but did predict both SF subscales and PWI total scores. CONCLUSIONS Trans women perceived themselves to be lacking social support. Given that social support is beneficial to quality of life and life satisfaction in those with gender dysphoria, this is of great concern. Though these findings have been derived from correlational results, extended research may highlight the value of clinicians helping trans women to seek out and maintain social support. Additionally, efforts could be made to educate and challenge attitudes of nontrans people towards those with gender dysphoria.

Caregiving and coping in carers of people with anorexia nervosa admitted for intensive hospital care

OBJECTIVE The aim of the study was to examine how carers cope practically and emotionally with caring for individuals with anorexia nervosa who require intensive hospital care. METHOD This study explores objective burden (time spent with caregiving and number of tasks), subjective burden (psychological distress), and social support in a sample of parents (n = 224) and partners (n = 28) from a consecutive series of patients (n = 178) admitted to inpatient units within the United Kingdom. RESULTS Most time was spent providing emotional support and less with practical tasks. Time spent with caregiving was associated with carer distress and was fully mediated by carer burden. This was ameliorated by social support. Partners received minimal support from others, and we found similar levels of burden and distress for mothers and partners. DISCUSSION The data indicate that professional and social support alleviates carer distress and may be of particular value for partners who are more isolated than parents. The data also suggest that time spent with practical support may be of more value than emotional support.

Non-suicidal self-injury and suicidality in trans people: A systematic review of the literature

Literature has described high levels of mental health problems among trans people, such as depression, resulting in increased levels of non-suicidal self-injury (NSSI) behaviour and suicidality (suicidal thoughts, suicide attempts and suicide rates). With the aim of systematically reviewing the available literature in this field, this study identifies 31 papers that explore the rates of NSSI and suicidality in trans people. From reviewing the literature, it was revealed that trans people have a higher prevalence of NSSI and suicidality compared to the cisgender (non-trans) population. There appear to be some gender differences within these rates, with trans men at a greater risk for NSSI behaviour. Prevalence rates differ depending on the different stages of transition, but they are still overall greater than the cisgender population. The study concludes that trans individuals are at a greater risk of NSSI behaviour and suicidality than the cisgender population, and discusses risk factors and the need to develop effective preventative interventions.

Non-suicidal self-injury in trans people: associations with psychological symptoms, victimization, interpersonal functioning, and perceived social support

INTRODUCTION There is a paucity of systematic research in the area of non-suicidal self-injury (NSSI) in trans people. AIM The aim of this study was to investigate the prevalence of NSSI in trans people and the associations with intra- and interpersonal problems. METHODS Participants were 155 untreated individuals with a diagnosis of transsexualism (according to International Classification of Disease-10 criteria) attending a national gender identity clinic. MAIN OUTCOME MEASURES All participants completed the Self-Injury Questionnaire, the Symptom Checklist-90-Revised, the Rosenberg Self-Esteem Scale, the Hamburg Body Drawing Scale, the Experiences of Transphobia Scale, the Inventory of Interpersonal Problems-32, and the Multidimensional Scale of Perceived Social Support. RESULTS The sample consisted of 66.5% trans women and 33.5% trans men and 36.8% of them had a history of engaging in NSSI. The prevalence of NSSI was significantly higher in trans men (57.7%) compared with trans women (26.2%). Trans individuals with NSSI reported more psychological and interpersonal problems and perceived less social support compared with trans individuals without NSSI. Moreover, the probability of having experienced physical harassment related to being trans was highest in trans women with NSSI (compared with those without NSSI). The study found that with respect to psychological symptoms, trans women reported significantly more intrapersonal and interpersonal symptoms compared with trans men. Finally, the results of the regression analysis showed that the probability of engaging in NSSI by trans individuals was significantly positively related to a younger age, being trans male, and reporting more psychological symptoms. CONCLUSIONS The high levels of NSSI behavior and its association with interpersonal and interpersonal difficulties and lack of social support need to be taken into consideration when assessing trans individuals. The effect of cross-sex hormones and sex reassignment surgery on psychological functioning, including NSSI behavior, as part of the transitional journey of trans individuals should be explored in future studies.

Prevalence of Eating Disorders amongst Dancers: A Systemic Review and Meta-Analysis

Eating disorders in dancers are thought to be common, but the exact rates remain to be clarified. The aim of this study is to systematically compile and analyse the rates of eating disorders in dancers. A literature search, appraisal and meta-analysis were conducted. Thirty-three relevant studies were published between 1966 and 2013 with sufficient data for extraction. Primary data were extracted as raw numbers or confidence intervals. Risk ratios and 95% confidence intervals were calculated for controlled studies. The overall prevalence of eating disorders was 12.0% (16.4% for ballet dancers), 2.0% (4% for ballet dancers) for anorexia, 4.4% (2% for ballet dancers) for bulimia and 9.5% (14.9% for ballet dancers) for eating disorders not otherwise specified (EDNOS). The dancer group had higher mean scores on the EAT-26 and the Eating Disorder Inventory subscales. Dancers, in general, had a higher risk of suffering from eating disorders in general, anorexia nervosa and EDNOS, but no higher risk of suffering from bulimia nervosa. The study concluded that as dancers had a three times higher risk of suffering from eating disorders, particularly anorexia nervosa and EDNOS, specifically designed services for this population should be considered.

A case series evaluation of a modified version of interpersonal psychotherapy (IPT) for the treatment of bulimic eating disorders: a pilot study.

OBJECTIVE To determine the therapeutic outcome of a modified form of (IPT-BNm) amongst patients with Bulimia Nervosa (BN) and Eating Disorders Not Otherwise Specified (EDNOS). METHOD Following initial assessment, 59 patients with diagnoses of BN or EDNOS entered treatment in the form of 16 sessions of IPT-BNm. At initial assessment, patients completed measures of general psychopathology (SCL-90), Self esteem (RSE), eating psychopathology (EDE-Q), interpersonal functioning (Inventory of Interpersonal Functioning; IIP-32) and depression (BDI). At the middle and end of treatment, EDE-Q, IIP-32 and BDI measures were repeated. RESULTS By the middle of therapy, patients had made significant improvements in terms of their eating disordered cognitions and behaviours (including reductions in EDE-Q scores, bingeing and self-induced vomiting), interpersonal functioning and levels of depression. CONCLUSIONS IPT-BNm is an effective treatment for patients with Bulimic Eating Disorders and appears to work quickly, as there were significant reductions in eating disorders symptoms within the first eight sessions of treatment.
