Transgender individuals and suicide attempt and mortality in Denmark

Previous studies have suggested that transgender individuals may constitute a high-risk group in terms of suicide attempts and suicide, but the existing knowledge was primarily based on surveys. Large, population-based studies were lacking.

DRISP conducted an analysis of suicide attempts and mortality among transgender individuals in Denmark. The study aimed to investigate whether transgender individuals in Denmark have higher rates of suicide attempts and mortality compared to non-transgender individuals.

The study was nationwide and based on registry data, and it included over 6.6 million individuals born in Denmark, aged 15 or older, and residing in the country at some point between January 1, 1980, and December 31, 2021. Transgender identity was determined through national hospital records and administrative records of legal gender change. The results showed that transgender individuals had significantly higher rates of suicide attempts, suicides, non-suicidal deaths, and overall mortality compared to non-transgender individuals.

The results indicated that despite decreasing suicide attempt and suicide rates over the 42 years examined, the adjusted rates remained significantly elevated in the recent periods up to and including 2021 for all the categories studied. Transgender individuals had a 3.5 times higher risk of suicide and a 7.7 times higher risk of suicide attempts than the general population.

The study emphasizes the need for attention to the specific challenges faced by transgender individuals and the implementation of measures to reduce suicide attempts and improve their overall health and well-being.

The head of program at the Danish Research Institute for Suicide Prevention (DRISP), Annette Erlangsen, stated: “We knew from foreign studies that transgender individuals have an increased risk of suicidal behavior, so it is good to be able to put precise numbers on the relationship. Transgender individuals who have suicidal thoughts may be less likely to seek help from existing psychiatric services because they do not want it to be documented in their patient records, possibly hindering access to later treatment. Danes see ourselves as pioneers in the LGBT+ field, and we have suicide prevention treatments that work, but we lack solutions to this problem.”

Morten Frisch, a senior physician at Statens Serum Institut and the head of the population study Project SEXUS, adds: “Our new study stands out as the world’s first nationally comprehensive study on the suicidal behavior and mortality of transgender individuals. Hopefully, the clear results of the study will help focus attention on the challenges in life that significantly increase the risk of suicide attempts and death among transgender individuals. It is an unmistakable and concerning sign of distress among Danish transgender individuals when this group has an almost eight times higher prevalence of suicide attempts than other Danes.”

Susanne Branner Jespersen, the secretariat manager at LGBT+ Denmark, states: “These are very alarming figures, which unfortunately we were already too familiar with. The numbers indicate that there is a long way to go before we destigmatize what it means to be transgender and create better conditions for them throughout their lives. We all have a great responsibility for this, and the current public debate about what it means to be transgender does not always promote understanding.”

The study was published in the prestigious journal: JAMA Network.

Risk for suicide attempt in the offspring of parents with suicide attempt.

In this study we use data from Danish, nationwide registers to investigate risk of suicide attempt in individuals whose parents have attempted suicide. Results show that parental suicide attempt is associated with a 3-fold increased risk of suicide attempt in the offspring. Risks are highest if the parent attempted suicide during early childhood of the offspring. Risks were slightly higher for children of mothers than fathers with suicide attempt. Suicide attempt in a stepparent was associated with a 1,7 fold risk of suicide attempt in the stepchild. Analyses are adjusted for important socioeconomic confounders.

iCare: Psychoeducation for parents of children with suicide attempt

Each year, there are approximately 11,000 suicide attempts in Denmark, mainly among young people under the age of 25. Clinicians who provide support to young people after suicide attempt are often consulted by the young person’s parents who are keen to support their child. To provide better information to parents, DRISP has developed a website for this target group and in collaboration with parents with lived experiences. This website is now testing to determine whether parents find it useful. In connection with the project, several qualitative studies have been conducted, which are described here below.

Study 1: Existing evidence regarding the experiences of relatives caring for people with suicide attempts was reviewed. A total of 12 studies on the subject were included and a meta-ethnographic synthesis was conducted. The results showed that relatives of people with suicide attempts often pass through four unique phases, which each represent different perspectives and emotions. It was also found that interaction with other relatives who experienced comparable challenges made it easier for relatives to pass through these phases and helped them to find themselves in new and challenging situations.

Study 2: Interviews were conducted with 21 Danish parents of children with suicidal behavior. The results of the study showed that parents’ perceived that their identity was affected by their children’s suicidal acts. The perceived identity of the parents passed through up to three interrelated phases. Each phase reflected a different perspective of their identity and was developed in social interaction with other people. It was also found that not all parents were able to re-establish their parenting agency.

Suicide risk associated with psychiatric hospitalization

People with mental illness have an increased risk of suicide. Previous Danish studies have shown that the risk is elevated in the period shortly after admission and especially after discharge from psychiatric hospital. Trine Madsen from DRISP has in an updated analyses investigated whether this is still the case or whether the recent decades of efforts in the field have led to an improved situation for people with mental vulnerability.

Register data for the entire Danish population aged 15 years or older in the period 1995-2016 were included in the analysis.

Men and women who were in inpatient treatment for a psychiatric disorder had a suicide rate of 237 and 322 per 100,000, respectively, compared to men and women who had never been inpatients. In the first week after discharge, the suicide rate was 225 and 425 times higher for men and women, respectively, when compared to those who had never been admitted. About 6% of all suicides amongst males and 13% amongst females occurred during the first week of a psychiatric admission or discharge. The study also showed that the suicide rate amongst admitted patients fell by 2.5% per year until 2009, after which the rate rose by 7.5% per year.

The study’s conclusion was that – despite falling suicide rates – the period around admission and discharge from a psychiatric hospital is still associated with an extremely high risk of death by suicide.

Suicide risk according to highest level of psychiatric service received

Different patient groups are seen across psychiatric sectors and it is relevant to know which groups are at imminent risk of suicide. In this project, the risk of suicide is examined according to the highest level of psychiatric service received. The level will be graded according to severity as well as by type of contact, such as psychiatric admission, psychiatric ER visit, psychiatric outpatient, psychiatric medicine.

Lyme disease and risk of suicidal behaviour suicidal adfærd

The Borrelia bacterium, which exists in ticks, can develop into an infectious disease in humans when bitten. This disease is known as lyme disease (or Lyme Borreliosis) Infections have previously been associated with an increased risk of suicidal behavior. Trine Madsen from DRISP has, in collaboration with colleagues, investigated whether Lyme Borreliosis was linked to increased prevalence of psychiatric diseases and suicidal behavior.

Using register data for all persons living in Denmark from 1994 to 2016 (n=6,945,837), patients diagnosed with Lyme Borreliosis were identified based on hospital diagnoses. Their risk of developing psychiatric diseases and suicidal behavior was analyzed.

The results showed that persons who developed Lyme Borreliosis (i.e., an infection after a tick bite) had a 1.3-fold higher rate of psychiatric diseases, as well as a 2-fold higher rate of suicide attempts and a 1.75-fold higher suicide rate when compared to the background population. The highest risk of developing a psychiatric disease was observed within the first 6 months after persons developed Lyme Borreliosis. If the person had had multiple incidents of Lyme Borreliosis, this was associated with an increasing risk of suicide attempts.

In conclusion, the study showed that persons diagnosed with Lyme Borreliosis at Danish hospitals have an increased prevalence of psychiatric diseases, suicide attempts and suicide.

Combat exposure and risk of suicide attempt in previously deployed soldiers

Traumatizing events such as exposure to war can affect mental health. After World War I, the term “shell shock” was used to describe the shock effect that individuals who experienced the war may suffer. Although there is an increased awareness of adverse effects for deployed soldiers, stories of individual events, which seem to question the support that provided to veteran soldiers, often find their way to media reports.

To gain deeper insights into the stress experienced by deployed combat soldiers, DRISP has conducted a research project together with the Danish Veteran Center.

The study included more than 12,000 Danish veterans deployed on an international mission in the years 1997-2016 and who participated in a questionnaire survey after returning home. In the survey, they were asked about the level of combat exposure and experiences of the consequences of war. Figures from national registers administered by Statistics Denmark and the Danish Health Authority showed that a total of 83 veterans had had a suicide attempt after returning home. The findings of the study showed that veterans with a higher level of combat exposure have an 8% higher risk of suicide attempt after returning home compared to veterans with a lower level of combat exposure. The findings also confirmed that the increased risk of suicide attempt applied to veterans who, in addition to combat exposure, had symptoms of PTSD and/or depression. No association was found between having witnessed the consequences of war and suicide attempt.

The results point to the importance of attention towards those who have been exposed to combat and subsequently develop PTSD or depression, as this group were at greater risk of later suicide attempt.

Suicide rates in Nordic prisons 1999-2016

International research has shown an increased suicide rate among people in prison.  However, studies have yet to address age structural differences. In this longitudinal the suicide rates among male prisoners is compared to the general population in three Nordic countries, Denmark, Iceland, and Norway,  while adjusting for age differences.

Findings from the study shows that men in prison have a 7-fold higher suicide rate compared to the background population in Denmark, Iceland, and Norway and when accounting for age differences. For females, a rate 18-fold higher suicide rate was found among those in prison when compared to the general population. Over the 17-year study period, the suicide rate of people in prison decreased from 129 per 100,000 in 1999 to 70 per 100,000 in 2016. This decline was steeper that the decline observed for the suicide rate in the general population in the Nordic countries.

Call volume to a national suicide hotline, the Lifeline

It is estimated that between 50-60% of the people who call helplines for suicide prevention are in an acute crisis, and up to 56% have had a previous suicide attempt. It is therefore important to answer these calls.

The counselors of the Danish telephone helpline for suicide prevention, “Livslinien,” answer more than 14,000 calls per year. However, many calls still go unanswered. DRISP is collaborating with the Danish telephone helpline in an ongoing research project to investigate how many calls are answered and at what times of day the peaks.

In a first research project, the number of calls and characteristics of the people who called Livslinien were investigated. Data on all answered calls in the period 2018-2019 were analyzed. The data material consisted of records that counselors make after each counseling session and included socio-demographic information as well as an assessment of the person’s suicide risk.

Ove a 2-year period, a total of 42,393 calls were answered. In more than half of all calls, the person seeking counseling was evaluated to be at risk of suicide – and in 37% of all calls, the person was considered to be at high risk of suicide.

The study also showed that women, younger people, those with a history of previous suicide attempts, and those who reported problems related to self-harm, mental illness, sexual abuse, substance abuse, and physical health problems were more likely to be considered at risk of suicide, as evaluated by counselors.

The results of the study highlight the importance of helplines for suicide prevention and the need to ensure that these are adequately staffed in order to meet the demand.

Bereaved by suicide: psychological mechanism

Losing a loved one to suicide can be a traumatic and stressful experience, and studies show that bereaved by suicide themselves have an increased risk of stress-related illnesses and suicidal behavior. To determine the burden related to being bereaved, Annette Erlangsen at DRISP is involved in an international research project with researchers from University College London.

The study examined register data on 32,248 individuals living in Denmark who died by suicide in Denmark between 1980 and 2016, as well as identifying their relatives in the form of parents, children, siblings, and partners.

Having lost a loved one to suicide was associated with a 2.8 times higher risk of suicide compared to people who had not lost a loved one. The study also showed that 0.69% of all suicides in Denmark could be prevented if all factors that increase the risk of suicide among relatives of people who have died by suicide could be addressed. This corresponds to 60% of suicides among bereaved by suicide.

Bereaved by suicide have an increased risk of developing suicidal behavior themselves, and, although these suicides only account for a relatively small proportion of the total number of suicides, it is important to provide support to this group.

Bereaved by suicide and affected by suicide: how many receive help?

Every year about 600 suicide deaths and 11,000 suicide attempts are recorded in Denmark. Next to each suicidal act are numerous relatives and other next of kin who are deeply affected. Specialised support for bereaved and affected is being provided by volunteer organisations and it is unclear how many receive help. This research project will seek to map how many bereaved by suicide and affected by suicidal behaviour receive support from Nefos, one of the Danish volunteer organisations.

MYPLAN – a self-help tool for management of crisis

People who have had a suicide attempt have a significantly higher risk of repeated suicidal behaviour. MYPLAN was created with the intention of being a self-help tool for management of suicidal crisis. This project consists of 1) a qualitative study of stakeholders on improvements to MYPLAN; 2) a randomized clinical trial to evaluate MYPLAN’s efficacy in reducing suicide intent among persons at risk of suicide, and 3) a person-centered evaluation of the MYPLAN to identify barriers and facilitators to its general implementation. The RCT was initiated in 2019 and is currently ongoing. Following studies have been published :

Psycho-social speech therapy in the Danish Suicide Prevetion Clincs

Although deliberate self-harm is a strong predictor of suicide, evidence for effective interventions is missing. The aim of this study was to examine whether psychosocial therapy after self-harm was linked to lower risks of repeated self-harm, suicide, and general mortality.
Our findings show a lower risk of repeated deliberate self-harm and general mortality in recipients of psychosocial therapy after short-term and long-term follow-up, and a protective effect for suicide after long-term follow-up, which favour the use of psychosocial therapy interventions after deliberate self-harm.
