BackgroundTrans and gender diverse (TGD) young people worldwide experience high rates of poor mental health; however, these rates were unknown in Australia. In addition, how negative life events affect the mental health of TGD young people has been largely unexplored.MethodsThis paper reports on novel mental health findings of Trans Pathways, the largest study ever conducted in Australia with trans (transgender) and gender diverse young people (N = 859; aged 14–25 years). The study was an anonymous online cross-sectional survey undertaken in 2016. Logistic and linear regression models were used to test associations between mental health outcomes and negative life experiences.ResultsTGD young people in Australia experience high levels of mental distress, including self-harming (79.7%), suicidal thoughts (82.4%), and attempting suicide (48.1%). Three in four participants had been diagnosed with depression and/or anxiety (74.6% and 72.2%, respectively). Many TGD young people had been exposed to negative experiences such as peer rejection (89.0%), precarious accommodation (22.0%), bullying (74.0%), and discrimination (68.9%). Most poor mental health outcomes were associated with negative experiences. The strongest associations were found for precarious accommodation and issues within educational settings. For example, participants with a prior suicide attempt were almost six times more likely to have experienced issues with accommodation, including homelessness.ConclusionsThe current results highlight the urgent need for better mental health care and provide insight into areas for targeted mental health interventions. These findings are pertinent for clinicians working with trans young people and wider society.

BackgroundDietary assessment methods that can provide high quality data while limiting participant burden and resource requirements in epidemiological research are highly sought after and continue to evolve. The use of mobile phone technology in research has increased rapidly over the last decade and offers multiple advantages to the researcher over traditional data collection methods. This study tested the acceptability and relative validity of a commercial smart phone application (app) for use as an epidemiological dietary assessment tool, compared with a traditional dietary assessment method.MethodsStudy participants completed a 4-d food diary using a modified version of the Easy Diet Diary app and two 24-h dietary recalls during the same week, for comparison. At the end of data collection, participants completed a questionnaire on their experience with both methods. Average proportions of energy from macronutrients and fibre, iron, and calcium densities from the app and 24-h recalls were compared after log transformation, by calculating mean agreement, limits of agreement (LOA), and Pearson’s correlations. The prevalence of dietary under-reporting was compared in each method using the Goldberg method.ResultsA total of 50 adults (82% women) provided data for analysis (mean age, 31 y; mean BMI, 22.4 kg/m2; 14% overweight or obese). Participant feedback showed high levels of acceptance of the app; 83% preferred using the app to completing 24-h dietary recalls. The average difference in energy intake (mean agreement) between methods was 268 kJ/d. For all intakes except alcohol, the average difference between methods was not significantly different from zero. Most limits of agreement were within an acceptable range. The prevalence of dietary misreporting was similar in both methods.ConclusionsThese findings demonstrate good feasibility for applying this commercially-developed smartphone app in epidemiological research.Electronic supplementary materialThe online version of this article (10.1186/s12937-018-0315-4) contains supplementary material, which is available to authorized users.

Purpose: Trans and gender diverse (TGD) young people have reported high levels of mental distress in research studies, specifically depression, anxiety, self-harming, and suicidal behaviors. Rates of abuse are also high in TGD populations, but little is known about how this relates to mental health in populations of TGD young people. This study sought to examine associations between experiences of abuse and mental health outcomes. Methods: A cross-sectional study design was used. An anonymous online questionnaire was conducted to determine rates of abuse among Australian TGD young people (N = 859) and the potential association with poor mental health. Primary outcomes of interest were self-reported psychiatric diagnoses, self-harm and suicidal behaviors, and current anxiety and depressive symptoms. Results: Exposures to six forms of abuse are reported in this article: extrafamilial physical abuse, familial physical abuse, extrafamilial sexual abuse, familial sexual abuse, abuse within an intimate relationship, and other familial abuse (including emotional or verbal abuse and neglect). All six forms of abuse measured were associated with poor mental health overall; risk estimates for some forms of abuse were much stronger than others. Conclusion:The current findings have wide-ranging implications for clinical practice. Those working in TGD health care need to be aware of the high prevalence of violence and abuse among TGD young people and the association with poor mental health outcomes. The findings also have implications for broader societal change and interventions targeting increasing parental support to reduce familial violence against TGD young people.
