Factors associated with suicide attempts among Australian transgender adults

Transgender, including gender diverse and non-binary (trans) people are a highly marginalised group in our community with alarmingly high rates of suicidality (ideation and non-fatal behaviours) and mental health morbidities [1‐3]. High quality empirical evidence and data (such as from a census) describing the size of the trans population are limited, but a systematic review of studies published internationally from 2009 to 2019 found estimates ranged from 0.5 to 4.5% of the adult population [4]. Within an Australian-context, despite universal public health care and anti-discrimination laws at the State and Federal level, trans adults experience high levels of discrimination and are four times more likely than the general population to be diagnosed with depression, with over 40% self-reporting previous suicide attempts [5‐7]. Various human rights challenges remain; in many Australian States and Territories, it is not possible to obtain legal gender recognition without first having gender affirmation surgery. Moreover, access to gender affirmation surgery is not covered by the national Medicare public health scheme and is cost prohibitive for many people.

Suicide attempts and suicide deaths occur due to a complex interaction between biological, psychological and psychosocial risk factors. This may include genetic predisposition to depression and anxiety [8, 9], minority stress and stressful life events, unemployment and financial stress [10‐12], quality of support networks [13‐17], discrimination, violence [18‐20] and barriers to accessing healthcare and support services [21].

Trans-specific factors for suicidality is an under-researched area, but several risk and protective factors have been identified. Research has increasingly focused on how cissexism, or the belief that cisgender people are ‘normal’, ‘natural’ and ‘superior’ delimits opportunities for trans health and wellbeing [22]. Gender-based victimisation, including verbal abuse, peer rejection, threats of violence and physical assault has been well documented among trans adults [3, 23, 24]. Similarly, there is growing evidence of institutionalized cissexism, manifesting as heightened rates of trans unemployment, reduced access to housing, education and healthcare (including gender affirming healthcare), which contributes to diminished mental health and wellbeing by way of elevated feelings of shame, hopelessness and isolation [24‐29]. Systemic barriers are associated with increased risk of housing instability, financial stress and violence [30].

Rather than focusing on the deleterious effects of cissexism, research has begun to illuminate factors that protect against suicidality and mental health comorbidities. For example, in trans people who wish to access hormones, being able to do so reduces mental distress, and improves quality of life [31, 32]. Similarly, trans adults who desire and are able to access gender affirming surgery report stronger mental health as compared to trans adults who cannot access surgeries [33]. Social support from family, friends and connection with the trans community and experiencing lower levels of structural discrimination are further protective factor against suicidality and suicide attempts [13‐17].

Gender plays a role. In Australia, young cisgender men and those presumed to be men who live in non-metropolitan areas have the highest suicide rates and are less likely to seek assistance for depression or other mental health problems [34]. Data from many countries worldwide show that people presumed male have higher rates of suicide compared to people presumed female [35]. The precise reasons for the gender discrepancy are unclear, however possible explanations for higher rates of suicide in people presumed male include more violent, immediately lethal means of suicide, higher levels of suicidal intent and greater reticence to seek assistance from doctors for mental health support [36, 37].

In the general population, it is known that unemployment, physical assault and perceived discrimination increases risk for suicide ideation and suicide attempts [12, 38, 39]. We hypothesised that people who reported known risk factors for suicidal behaviour; residing in rural areas, unemployment, experienced difficulty accessing gender-affirming interventions, known history of depression or anxiety, had perceived discrimination and experiences of assault, would have a higher odds of reporting a history of suicide attempts. Given the lack of data describing risk or protective factors among Australian trans adults, this exploratory analysis aimed to assess factors associated with a lifetime history of attempted suicide in order to guide suicide prevention strategies and interventions.

This anonymous online survey of trans adults utilised a non-probability snowball sampling technique. Inclusion criteria for participants were assessed by a positive response to three screening questions: a) Australian residency; b) aged 18 years or older and c) self-identify as trans or gender diverse (defined as a ‘yes’ response to the question ‘Do you currently identify or have you previously identified as transgender or gender diverse?’). The inclusion of those who had previously identified as trans was intended to include those who identified as their affirmed gender (male, female or non-binary) rather than with the term transgender. Individuals were eligible to complete the survey on one occasion only and duplicate responses from the same Internet Protocol address were excluded. All included individuals had discordance between their assigned sex at birth and their gender identity. Survey questions were all optional. SurveyMonkey (SurveyMonkey Inc. San Mateo, California, USA) was used to collect responses to the survey between 1st September 2017 and 31st January 2018. Given that this was an anonymous survey, written informed consent was not possible and was waived by the institutional ethics committee; however, the survey preamble outlined that completion of the survey implied consent. The study was approved by the Austin Health Human Research and Ethics Committee (HREC/17/Austin/372).

Participants were asked a range of questions, with data pertaining to the health care needs and priorities of participants which are published elsewhere [7, 40]. The full version of the survey is available in the supplementary appendix at https://​doi.​org/​10.​1089/​lgbt.​2020.​0178 [7]. Participants were asked ‘Have you ever intentionally self-harmed?’ (response options of ‘yes’, ‘no’ or ‘prefer not to say’) and ‘Have you ever attempted suicide?’ with response options of ‘yes’, ‘no’ or ‘prefer not to say’. We specifically assessed if the following 10 factors were risk or protective factors for a positive (‘yes’) response for a lifetime history of attempted suicide.

There was a total of 964 responses to the survey, however, after excluding participants who did not fit the selection criteria and duplicate responses, there was a total of 928 eligible survey responses.

Participant characteristics are shown in Table 1. Responses were received from all states and territories of Australia, with the majority residing in major city areas. The median age of participants was 28 years [interquartile range 23–39]. Sixty three percent of trans adults reported a lifetime history of intentional self-harm (n = 577), while 43% reporting ever having attempted suicide (n = 394). This compares to a lifetime prevalence of self-injury in the Australian general population of 8.1% and previous suicide attempts of 3.3% [41, 42]. From univariate analysis, there was no statistically significant difference in the proportion of suicide (p = 0.6) or self-harm (p = 0.08) between different states of residence. Access to and desire for gender affirming surgeries are presented in Table 2.

Variables which were associated with increased odds of a lifetime history of suicide attempts are shown in Table 3. Self-reported unemployment, desiring gender-affirming surgery in the future, depression, physical assault, and institutional discrimination were all associated with higher odds of reporting a previous suicide attempt. There was no association with anxiety, difficulty accessing hormones or location of residence (rural versus metropolitan), nor was access to trans support groups a protective factor. Being presumed male at birth was associated with lower odds of reporting a lifetime history of suicide attempts. Due to the low number of intersex individuals (n = 5), a valid odds ratio cannot be estimated and hence was not reported in Table 2. A sensitivity analysis was performed excluding those 5 participants and the results remains unchanged.

This large community survey provides preliminary insight into the factors associated with suicidality in the Australian trans community. Being unemployed, reporting a diagnosis of depression, desiring gender affirming surgery, a history of physical assault and experiences of institutional discrimination were all factors associated with increased odds of a lifetime history of suicide attempts. Being presumed male at birth was associated with lower odds of suicide attempt.

While the self-reported suicide attempt rate of trans participants is 10-times higher than that reported for the general Australian population, this rate converges with data on Australian trans youth and similar cohort studies conducted in Euro-Western settings [6, 41‐43]. This pattern of convergence suggests that health disparities and systemic social inequities are not confined to a specific developmental time frame nor geographic locality. Notably, we found intentional self-harm rates (63%) were even higher than the rate of suicide attempt, but previous evidence has shown that in the Australian population, self-harm can occur in the absence of suicidal thoughts, often used as a means of managing difficult emotions [42]. While beyond the scope of the current analysis, it may be that persistent social exclusion and acts of erasure result in elevated feelings of shame, hopelessness and isolation-factors associated with self-harm [24‐29].

Due to widespread cissexism and transphobia, physical assault is an all-too-common experience within the trans community. It was reported by 21% of respondents and was associated with a 100% increase in the odds of a lifetime suicide attempt. Physical assault has consistently been associated with poor mental health outcomes and a higher risk of suicide [19, 20, 44]. Critically, being physically assaulted because of a perpetrator’s transphobic prejudice is associated with a higher probability of suicide attempt than a physical assault not attributed to prejudice, or experiencing institutional discrimination alone without assault [45].

Additionally, experiences of institutionalised discrimination were reported at a high frequency. In our study, this included discrimination while accessing healthcare (including gender affirming healthcare), in employment, housing, and accessing government services. In a US-based study of 6450 trans people, an extraordinary 90% reported experiencing harassment, mistreatment or discrimination in workplaces, housing and in healthcare settings due to prejudice related to their trans-status or took actions such as hiding their identity to mitigate risk [3]. Specifically, service denial in healthcare has a profound impact correlated with elevated rates of attempted suicide [21]. Social and institutional discrimination has been found to negatively impact trans people’s mental health and has been consistently demonstrated to be a risk factor for attempted suicide, underscoring the need for multi-level interventions to enable timely, rights-based and culturally safe access to gender affirming and general healthcare, end discrimination and protect the trans population across every domain of life [18, 29, 46, 47].

In addition to discrimination, unemployment was associated with a 54% higher odds of lifetime suicide attempt. The trans unemployment rate of 19% is three times higher than the general Australian population (5.5%) [48]. In general population studies, unemployment and financial precarity has been linked to suicidality, with the length of unemployment compounding the risk of suicide [10‐12]. The impact of employment on mental and physical health, socioeconomic status and quality of life is profound [49, 50]. Perceived stress in everyday life is known to increase the risk of unemployment, yet unemployment and sustained economic hardship can also directly negatively affect physical, psychological and cognitive functioning [51‐54]. Poverty arising from unemployment may additionally limit an individual’s ability to access gender-affirming healthcare, particularly gender-affirming surgery which is associated with large out-of-pocket costs [3, 55]. Notably, there are many potential barriers to employment for trans people such as persistent challenges being affirmed and respected by employers and colleagues using the correct name, gender and pronouns, to being terminated, looked over for promotions and facing discrimination and violence at work, to discrimination in basic housing and healthcare and the impact of mental health conditions such as depression and anxiety on an individual’s ability to seek or maintain employment [29, 56]. Moreover, 33% reported perceived discrimination from employment, and whilst it was not directly assessed in the survey questions, workplace environments that expose individuals to discrimination have been found elsewhere to impact on an individual’s mental health and ability to maintain employment [29].

Self-reported lifetime diagnoses of depression were high in our participants, and this was associated with an over 200% increased odds of reporting a lifetime suicide attempt. Similarly, a lifetime history of major depressive disorder has been significantly associated with increased risk of suicidal ideation and attempted suicide in trans people worldwide [8, 9]. Depression in trans people is multifaceted, and there are various contributing factors; including discrimination, disclosure, social support, access to gender affirming healthcare, substance use and socioeconomic factors [57]. As such, strategies to lower the high rates of depression will need to be multifaceted, supported by accessible, specific and safe mental health support services for trans individuals, and improved access to gender affirming healthcare [58].

Anxiety, which is highly prevalent in the trans community, was not significantly associated with lifetime suicide attempt after adjustment, suggesting that the association is influenced by other confounders, such as depression. This is inline with some general population studies that have found that anxiety disorder alone is not associated with suicidality [59].

We demonstrate that trangender individuals who desire gender affirming surgery in the future experience 71% increased odds of reporting a lifetime suicide attempt. This is likely related to a number of intrapersonal and interpersonal factors, and barriers to healthcare access. Those individuals who desire gender affirming surgery generally experience body and/or social dysphoria related to that part of their body, resulting in mental health distress. Gender affirming surgeries may result in significant body changes that increase the likelihood that trans individuals will be read and understood by others as their affirmed gender. Those who desire but are yet to access surgeries may experience higher rates of misgendering, discrimination and violence due to gender non-conformity or ambiguous appearance [3, 60], which in turn may have an impact on mental health.

Access to gender-affirming surgery has been shown to improve mental health and quality of life indicators for those who have undertaken a surgical intervention to affirm their gender. [5, 33, 61] In an Australian study regarding surgery experiences and satisfaction, depression was reported in 34% of those individuals who had undergone at least some form of gender-affirming surgery, compared to 51% in those who desired but had not undergone surgery. [33] Our findings concur with previous research that those who want surgery but have yet to access it, are at significantly increased risk of suicide.

Desire for gender affirming surgery in the future may also be related to healthcare access. One of the biggest barriers reported by trans individuals is a lack of access to healthcare due to the lack of healthcare professionals skilled in gender affirming healthcare [62]. Access to gender affirming surgery, in particular, poses significant barriers due to a lack of experienced surgeons, high cost, the lack of public funding and “gate-keeping” requirements, which can typically involve multiple, detailed assessments with two mental health professionals prior to surgery. Barriers to access, may therefore also contribute to mental health distress and suicality, as individuals are faced with long, complicated and often prohibitively expensive options for gender affirming surgeries.

Greater training, programs and clinical supervision for surgeons already conducting or wishing to conduct gender affirming surgery, along with full public funding for all gender-affirming surgeries is critical to address this healthcare gap in access to such medically necessary interventions.

Interestingly our findings show that trans women and non-binary participants presumed male at birth appeared to have a lower odds of suicide attempt and the converse is true for trans men and non-binary participants presumed female at birth. Whilst suicide deaths in the Australian population occur at higher rates in those recorded as male, there is a higher rate of suicidal ideation and suicide attempt in those presumed female at birth [63]. Certainly studies assessing suicide attempts in the trans community have shown variable gender distributions and inferences are unclear [64].

In the Australian general population, the rates of suicide tend to increase with increasing rurality. This is commonly associated with several factors, including essential services such as healthcare and mental health support. [65, 66] This study however, showed no statistically significant difference in lifetime suicide attempt between trans people living in inner city areas and those living in regional and remote areas. Protective factors that might mitigate the expected association between rurality and suicidality include reasons for living, the individual’s resilience and ability to self-regulate suicidal thoughts and feelings, familial and social support and optimism. [67, 68] However, there is relatively little research directly examining protective factors in the trans population and the experience of trans individuals and communities in regional and remote areas, an effect termed the ‘metronormative’ bias of trans research. [69] Seminal qualitative research conducted in the USA illuminates how trans experiences of resilience in regional and rural places rests upon other social positions (e.g., race, queerness, disability and sexuality). [70]

Previous research suggests that a lack of social support is associated with higher odds of psychological distress and lifetime suicide attempts, and that social support from the trans community is a protective factor against suicidal ideation and suicide attempts [17, 71]. Contrary to those studies, our study indicates that there is no significant association between being part of a trans support group and suicide attempts. Notably, our survey did not ask about community connection which is different from being a member of a support group, nor did the survey assess other forms of social support, such as that from family and friends, which has been shown to be a protective factor [13, 14, 16, 68].

Not all trans people desire gender affirming hormones in their transition. However, for those people who do, the ability to access hormones reduces mental distress [31, 32]. The highest rates of depression in trans people are in those who want hormones but have yet to use them or are unable to access them [5]. Despite the strong link between depression and suicidality, this study found no significant difference in suicidality solely based on access to hormones. Given that there may be many confounding factors that impact mental health independently of hormone therapy, such as access to other gender affirming medical procedures and psychotherapy, as well as social support, it is difficult to determine the independent effects of hormone therapy on quality of life [32]. There is also evidence that any form of gender affirming transition is beneficial, such as social transition and social acceptance [67].

There are multiple limitations to this online study utilising a non-probability snowball sampling approach. The online-based recruitment may explain the proportion of younger participants and the views of older trans people may not be accurately reflected. There may be self-selection bias and not all areas of Australia were represented equally as recruitment was not targeted. There was a predominance of respondents in South-Eastern states, which may be related to physical promotion of the study at one event in Victoria and New South Wales. However, distribution of respondents was similar to a previous 2013 Western Australian-based survey [5]. Depression, self-harm and suicide attempts were self-reported. Hence, it is not possible to confirm diagnosis or determine how individuals define their experiences (e.g. what constitutes self-harm versus a suicide attempt; diagnosis of clinical depression). We did not study completed suicide, however suicide attempts are a risk factor for suicide and reflect significant distress experienced. The survey was also designed to broadly explore healthcare and wellbeing in the trans community and as such, did not focus extensively on mental health and suicidality. This survey was, however, a platform for trans people in Australia to express their experiences and opinions anonymously and honestly. It provides valuable insight on the health needs and wellbeing of a marginalised community.

This large community survey highlights the high rates of attempted suicide, self-harm and depression in the trans community. Suicide attempts occur due to a complex interaction between socio-political, environmental, interpersonal and structural risk factors. Rather than suicidality perceived as inherent to the trans experience, trans people appear to exhibit higher rates of suicidality as a manifestation of social discrimination. Addressing these factors that contribute to suicidality and the mental health burden in the trans community must be made a priority. Dismantling barriers to gender affirming healthcare is paramount; as is tackling pervasive cissexism in order to reduce incidents of discrimination, stigmatization and violence. There is also an ongoing need to shift the discourse of the health and health needs of trans people away from a focus on risk and deficit, to align with a strength-based approach to illuminate factors that protect against suicidality and to promote resilience.
