Suicide attempt and suicide in refugees in Sweden - a nationwide population-based cohort study

Suicide risk and suicide risk factors among immigrants in Italy: A bi-center matched sample study

Italy has the third-largest immigrant population of European Union countries, but only a few research papers have examined suicide risk in immigrant psychiatric patients in Italy. The main aim of this paper was to compare suicidal ideation and suicide attempts in a sample of 304 psychiatric patients. We included 152 immigrant patients matched with 152 Italian patients admitted to the same wards during the same time period by age, gender, and diagnosis. We also investigated sociodemographic and clinical characteristics of the two samples including psychiatric diagnosis, age of illness onset, duration of illness, previous hospitalizations, length of hospitalization, previous suicide attempts, and substance and alcohol abuse. There were no differences between immigrant and Italian patients in either suicidal ideation (previous or current) or suicide attempts (previous or current). Immigrant patients were more likely to have a shorter duration of illness than the Italian patients and Italian patients were more likely to report substance abuse than were immigrant patients. Despite similar suicide rates between immigrants and Italian psychiatric inpatients, appropriate assessment of suicide risk in these patients is essential in implementing therapeutic suicide prevention strategies.

Differences in all-cause and cause-specific mortality due to external causes and suicide between young adult refugees, non-refugee immigrants and Swedish-born young adults: The role of education and migration-related factors

BACKGROUND

International migration has increased during the past years and little is known about the mortality of young adult immigrants and refugees that came to Sweden as children. This study aimed to investigate 1) the risk of all-cause and cause-specific mortality in young accompanied and unaccompanied refugees and non-refugee immigrants compared to Swedish born individuals; and 2) to determine the role of educational level and migrations-related factors in these associations.

METHODS

This register linkage study is based on 682,358 individuals (633,167 Swedish-born, 2,163 unaccompanied and 25,658 accompanied refugees and 21,370 non-refugee immigrants) 19-25 years old, who resided in Sweden 31.12.2004. Outcomes were all-cause mortality and mortality due to suicide and external causes. Hazard ratios (HR) and 95% confidence intervals (CI) were calculated using Cox regression models with a maximum follow-up to 2016.

RESULTS

After adjusting for covariates, all-cause mortality was significantly lower in non-refugee immigrants (aHR 0.70, 95% CI 0.59-0.84) and refugees (aHR 0.76, 95% CI 0.65-0.88) compared to Swedish-born individuals. The same direction of association was observed for mortality due to suicide and external causes. No differences between accompanied and unaccompanied refugees were found. Risk estimates for all migrant groups varied with educational level, duration of residency, age at arrival and country of birth. Further, the mortality risk of migrants arriving in Sweden before the age of 6 years did not significantly differ from the risk of their Swedish-born peers. Low education was a considerable risk factor.

CONCLUSION

In general, young adult refugees and non-refugee immigrants have a lower risk of all-cause and cause-specific mortality than Swedish-born individuals. The identified migrant groups with higher mortality risk need specific attention.

Prevalence and prevention of suicidal ideation among asylum seekers in a high-risk urban post-displacement setting

AIMS

Among asylum seekers in a high-risk unstable post-displacement context, we aimed to investigate the prevalence of and risk for suicidal ideation (study 1), and then to test whether and how Mindfulness-Based Trauma Recovery for Refugees (MBTR-R) may prevent or treat suicidal ideation (study 2).

METHODS

Study 1 was conducted among a community sample of N = 355 (31.8% female) East African asylum seekers in a high-risk urban post-displacement setting in the Middle East (Israel). Study 2 was a secondary analysis of a randomised waitlist-control trial of MBTR-R among 158 asylum-seekers (46.2% female) from the same community and post-displacement setting.

RESULTS

Prevalence of suicidal ideation was elevated (31%). Post-migration living difficulties, as well as posttraumatic stress, depression, anxiety and their multi-morbidity were strongly associated with suicidal ideation severity. Likewise, depression and multi-morbidity prospectively predicted the onset of suicidal ideation. Relative to its incidence among waitlist-control (23.1%), MBTR-R prevented the onset of suicidal ideation at post-intervention assessment (15.6%) and 5-week follow-up (9.8%). Preventive effects of MBTR-R on suicidal ideation were mediated by reduced posttraumatic stress, depression, anxiety and their multi-morbidity. MBTR-R did not therapeutically reduce current suicidal ideation present at the beginning of the intervention.

CONCLUSIONS

Findings warn of a public health crisis of suicidality among forcibly displaced people in high-risk post-displacement settings. Although preliminary, novel randomised waitlist-control evidence for preventive effects of MBTR-R for suicidal ideation is promising. Together, findings indicate the need for scientific, applied and policy attention to mental health post-displacement in order to prevent suicide among forcibly displaced people.

Prevalence and Factors Associated With Suicidal Ideation Among Adult Eritrean Refugees in Northern Ethiopia

Background

The present study assessed the prevalence of and factor associated with suicidal ideations among adult Eritrean refugees in Tigray, Ethiopia.

Methods

A community-based cross-sectional study was carried out among 400 adult refugees living in the Mai-Aini refugee camp in Tigray, Northern Ethiopia from September 2019 to May 2020. The response variable was suicidal ideation and was measured using World Mental Health (WMH) Survey Initiative Version of the World Health Organization Composite International Diagnostic Interview. We applied bivariate and multivariate logistic regression to determine predictors for suicide ideations. Odds ratios and p-values were determined to check the associations between variables, and a p-value <0.05 was considered as a cut-off for statistical significance.

Results

The prevalence of suicidal ideations was 20.5% (95% CI: 16.4%, 24.5%). Having previous history of trauma [AOR = 2.3, 95% CI: 1.4, 4.5], a history of chronic illness [AOR = 2.9, 95% CI: 1.3, 6.5], a family history of mental disorder [AOR = 3.08, 95% CI: 1.3, 7.06], and history of post-traumatic stress disorder [AOR = 5.7, 95% CI: 2.8, 11.5] were significantly associated with suicidal ideations.

Conclusions

This study showed that during the stay in the refugee camp, there was a high prevalence of suicide ideations compared to the prevalence of suicide ideations among the general populations of Ethiopia, Europe, and China, and the lifetime pooled prevalence across 17 countries. Having previous history of trauma, a history of chronic illness, a family history of mental disorder, and history of post-traumatic stress disorder were the factors statistically associated with the suicidal ideation.

Mental and somatic disorders and the subsequent risk of all-cause and cause-specific mortality in refugees, non-refugee migrants and the Swedish-born youth: a population-based cohort study in Sweden

OBJECTIVES

The aims were to investigate the associations between specific mental and somatic disorders and subsequent all-cause and cause-specific mortality (suicide, external and other causes) in young refugees and non-refugee migrants compared with Swedish-born individuals of similar age.

METHODS

In this register-based prospective cohort study, all 1 003 760 individuals (40 305 refugees, 31 687 non-refugee migrants as the exposure groups and the rest as the Swedish-born comparison group), 16-25 years old, residing in Sweden on 31 December 2004 were included. These individuals were followed regarding the outcome of all-cause and cause-specific mortality (suicide and external causes) between 2005 and 2016. The study population was also stratified according to any use of specialised healthcare for mental or somatic diagnoses before baseline (2000-2004). Cox regression models yielding crude and multivariate Hazard Ratios (HR and aHR, respectively) with 95% Confidence Intervals (CI) were used to investigate the afore-mentioned associations.

RESULTS

A lower proportion of both refugees (12%) and non-refugee migrants (10%) had college/university education compared with the Swedish-born individuals (17%). The proportion of unemployed (>180 days) among refugees (2.3%) and non-refugees (2.9%) was higher than the Swedish born (1.4%). Refugees and non-refugee migrants had about a 20% lower risk of all-cause mortality and external causes of mortality compared with Swedish-born individuals. An even greater reduction in suicide risk (aHR 0.51, 95% CI 0.37 to 0.70, and 0.63, 95% CI 0.49 to 0.82 for non-refugees and refugees, respectively) was found. When restricted to those with a mental or somatic disorder, a lower risk of both general and specific mortality was also found among both refugees and non-refugee migrants compared with Swedish-born individuals. Refugees had, however, equal point estimates of all-cause mortality associated with substance misuse disorder and neoplasms as their Swedish-born peers with these disorders.

CONCLUSIONS

With few exceptions, young migrants with specific mental and somatic disorders have a mortality advantage compared with their Swedish-born peers with the same disorders. Further research on protective factors is warranted.

Suicide rates amongst individuals from ethnic minority backgrounds: A systematic review and meta-analysis

BACKGROUND

Existing evidence suggests that some individuals from ethnic minority backgrounds are at increased risk of suicide compared to their majority ethnic counterparts, whereas others are at decreased risk. We aimed to estimate the absolute and relative risk of suicide in individuals from ethnic minority backgrounds globally.

METHODS

Databases (Medline, Embase, and PsycInfo) were searched for epidemiological studies between 01/01/2000 and 3/07/2020, which provided data on absolute and relative rates of suicide amongst ethnic minority groups. Studies reporting on clinical or specific populations were excluded. Pairs of reviewers independently screened titles, abstracts, and full texts. We used random effects meta-analysis to estimate overall, sex, location, migrant status, and ancestral origin, stratified pooled estimates for absolute and rate ratios. PROSPERO registration: CRD42020197940.

FINDINGS

A total of 128 studies were included with 6,026,103 suicide deaths in individuals from an ethnic minority background across 31 countries. Using data from 42 moderate-high quality studies, we estimated a pooled suicide rate of 12·1 per 100,000 (95% CIs 8·4-17·6) in people from ethnic minority backgrounds with a broad range of estimates (1·2-139·7 per 100,000). There was weak statistical evidence from 51 moderate-high quality studies that individuals from ethnic minority groups were more likely to die by suicide (RR 1·3 95% CIs 0·9-1·7) with again a broad range amongst studies (RR 0·2-18·5). In our sub-group analysis we only found evidence of elevated risk for indigenous populations (RR: 2·8 95% CIs 1·9-4·0; pooled rate: 23·2 per 100,000 95% CIs 14·7-36·6). There was very substantial heterogeneity (I²  > 98%) between studies for all pooled estimates.

INTERPRETATION

The homogeneous grouping of individuals from ethnic minority backgrounds is inappropriate. To support suicide prevention in marginalised groups, further exploration of important contextual differences in risk is required. It is possible that some ethnic minority groups (for example those from indigenous backgrounds) have higher rates of suicide than majority populations.

Suicide rates and suicidal behaviour in displaced people: A systematic review

Background

Refugees, and other forcibly displaced people, face mental distress and may be disproportionately affected by risk factors for suicide. Little is known about suicidal behaviour in these highly mobile populations because collecting timely, relevant, and reliable data is challenging.

Methods and findings

A systematic review was performed to identify studies of any design reporting on suicide, suicide attempts, or suicidal ideation among populations of displaced people. A sensitive electronic database search was performed in August 2020, and all retrieved studies were screened for relevance by two authors. Studies were categorised by the population being evaluated: refugees granted asylum, refugees living in temporary camps, asylum seekers, or internally displaced people. We distinguished between whether the sampling procedure in the studies was likely to be representative, or the sample examined a specific non-representative subgroup of displaced people (such as those already diagnosed with mental illness). Data on the rates of suicide or the prevalence of suicide attempts or suicidal ideation were extracted by one reviewer and verified by a second reviewer from each study and converted to common metrics. After screening 4347 articles, 87 reports of 77 unique studies were included. Of these, 53 were studies in representative samples, and 24 were based on samples of specific target populations. Most studies were conducted in high-income countries, and the most studied population subgroup was refugees granted asylum. There was substantial heterogeneity across data sources and measurement instruments utilised. Sample sizes of displaced people ranged from 33 to 196,941 in studies using general samples. Suicide rates varied considerably, from 4 to 290 per 100,000 person-years across studies. Only 8 studies were identified that compared suicide rates with the host population. The prevalence of suicide attempts ranged from 0.14% to 15.1% across all studies and varied according to the prevalence period evaluated. Suicidal ideation prevalence varied from 0.17% to 70.6% across studies. Among refugees granted asylum, there was evidence of a lower risk of suicide compared with the host population in 4 of 5 studies. In contrast, in asylum seekers there was evidence of a higher suicide risk in 2 of 3 studies, and of a higher risk of suicidal ideation among refugees living in camps in 2 of 3 studies compared to host populations.

Conclusion

While multiple studies overall have been published in the literature on this topic, the evidence base is still sparse for refugees in camps, asylum seekers, and internally displaced people. Less than half of the included studies reported on suicide or suicide attempt outcomes, with most reporting on suicidal ideation. International research networks could usefully define criteria, definitions, and study designs to help standardise and facilitate more research in this important area.

Prevalence of suicidal ideation and suicide attempts among refugees: a meta-analysis

Background

Suicidal ideation and attempts are one of the most serious mental health problems affecting refugees. Risk factors such as mental disorders, low socio-economic status, and stressful life events all contribute to making refugees a high-risk group. For this reason, this meta-analysis aims to investigate the prevalence of suicidal ideation and attempts among refugees in non-clinical populations.

Method

We searched PubMed, Web of Science, PubPsych, and PsycInfo for articles reporting (period) prevalence rates of suicidal ideation and attempts. Inclusion criteria were the population of refugees or asylum seekers (aged 16 years and older), assessment of the prevalence of suicidal ideation and attempts in empirical studies in cross-sectional or longitudinal settings, written in English, and published by August 2020. Exclusion criteria were defined as a population of immigrants who have lived in the host country for a long time, studies that examined children and adolescents younger than 16 years, and research in clinical samples. Overall prevalence rates were calculated using Rstudio.

Results

Of 294 matches, 11 publications met the inclusion criteria. The overall period prevalence of suicidal ideation was 20.5% (CI: 0.11–0.32, I² = 98%, n = 8), 22.3% (CI: 0.10–0.38, I² = 97%, n = 5) for women, and 27.7% for men (CI: 0.14–0.45, I² = 93%, n = 3). Suicide attempts had an overall prevalence of 0.57% (CI: 0.00–0.02, I² = 81%, n = 4).

Conclusion

There is a great lack of epidemiological studies on suicidal ideation and attempts among refugees. The high prevalence of suicidal ideation indicates the existence of heavy psychological burden among this population. The prevalence of suicide attempts is similar to that in non-refugee populations. Because of the large heterogeneity between studies, the pooled prevalence estimates must be interpreted with caution. The results underline the need for systematic and standardized assessment and treatment of suicidal ideation and attempts.

Suicidal ideation among recently arrived refugees in Germany

BACKGROUND

Refugees are considered a high-risk population for developing mental health disorders. Yet little research has been conducted on suicidal ideation among refugees resettled in Western high-income countries. In the present hstudy, suicidal ideation and its association with different socio-demographic, flight-related, and mental health-related factors were analyzed in recently arrived refugees in Germany.

METHODS

The study was conducted in a reception facility for asylum-seekers in Leipzig, where 564 newly arrived adult residents participated. The questionnaire included socio-demographic and flight-related questions as well as standardized instruments for assessing suicidal ideation (item 9 from PHQ-9), a variety of traumatic experiences (LEC-5), posttraumatic stress disorder (PCL-5), depression (PHQ-8), and somatic symptoms (SSS-8). Multiple logistic regression models were run to predict suicidal ideation in relation to different socio-demographic, flight, and mental health-related factors.

RESULTS

In total, 171 (30.3%) participants who had just or very recently arrived in Germany reported having experienced suicidal ideation within the two weeks prior to being assessed. Those who reported suicidal ideation also reported higher prevalence of somatic symptoms, posttraumatic stress disorder, depression, and experiences of sexual violence, as well as worse self-rated mental and physical health. In addition, there were significant independent associations between suicidal ideation and (1) younger age, (2) longer flight duration, (3) experiences of sexual violence, (4) symptoms of posttraumatic stress disorder, and (5) symptoms of depression.

CONCLUSIONS

The results emphasize the association between suicidal ideation and different clinically relevant mental health symptoms among newly arrived refugees in Germany. Special attention should not only be given to refugees suffering from symptoms of poor mental health, but also to those of younger age as well as refugees who have experienced sexual violence, as they might be affected by suicidal ideation whether or not they suffer from other mental health problems.

Country of birth, time period of resettlement and subsequent treated common mental disorders in young refugees in Sweden

BACKGROUND

Little is known regarding treatment for common mental disorders (CMDs) in young refugees. We aimed to identify (i) if the risk of treatment for CMDs in young refugees varies by their country of birth, compared with the Swedish-born population and (ii) if time period of resettlement influences these possible associations.

METHODS

All Swedish-born individuals and people who were granted refugee status, aged 16-25 years, living in Sweden on 31 December 1999, 2004 or 2009 (around 1 million people with 3-4% refugees in each cohort), were followed for 4 years for treated CMDs by linking register data. To facilitate stratified analyses by refugees' country of birth, the 2009 cohort was followed for 7 years with regard to specialized healthcare and antidepressant prescription due to CMDs. Hazard ratios with 95% confidence intervals were computed in crude and adjusted models.

RESULTS

Refugees in the 2009 cohort with 7-year follow-up had a 25% lower risk for treated CMDs, compared with the Swedish-born. Stratified analysis by country of birth showed a similarly lower risk regarding treated CMDs among refugees from all countries but Iran [hazard ratios (95% confidence intervals): 1.15 (1.05-1.26)] than their Swedish-born peers. No substantial effect of time period of resettlement was observed in the risk for treated CMDs in refugees.

CONCLUSIONS

Treatment for CMDs is lower in young refugees than in the majority population in Sweden, is stable across time, but varies with country of birth. Strategies to improve access to mental healthcare for young refugees are warranted.

Trajectories of antidepressant use before and after a suicide attempt among refugees and Swedish-born individuals: a cohort study

Background

To identify key information regarding potential treatment differences in refugees and the host population, we aimed to investigate patterns (trajectories) of antidepressant use during 3 years before and after a suicide attempt in refugees, compared with Swedish-born. Association of the identified trajectory groups with individual characteristics were also investigated.

Methods

All 20–64-years-old refugees and Swedish-born individuals having specialised healthcare for suicide attempt during 2009–2015 (n = 62,442, 5.6% refugees) were followed 3 years before and after the index attempt. Trajectories of annual defined daily doses (DDDs) of antidepressants were analysed using group-based trajectory models. Associations between the identified trajectory groups and different covariates were estimated by chi²-tests and multinomial logistic regression.

Results

Among the four identified trajectory groups, antidepressant use was constantly low (≤15 DDDs) for 64.9% of refugees. A ‘low increasing’ group comprised 5.9% of refugees (60–260 annual DDDs before and 510–685 DDDs after index attempt). Two other trajectory groups had constant use at medium (110–190 DDDs) and high (630–765 DDDs) levels (22.5 and 6.6% of refugees, respectively). Method of suicide attempt and any use of psychotropic drugs during the year before index attempt discriminated between refugees’ trajectory groups. The patterns and composition of the trajectory groups and their association, discriminated with different covariates, were fairly similar among refugees and Swedish-born, with the exception of previous hypnotic and sedative drug use being more important in refugees.

Conclusions

Despite previous reports on refugees being undertreated regarding psychiatric healthcare, no major differences in antidepressant treatment between refugees and Swedish-born suicide attempters were found.

Healthcare use before and after suicide attempt in refugees and Swedish-born individuals

PURPOSE

There is a lack of research on whether healthcare use before and after a suicide attempt differs between refugees and the host population. We aimed to investigate if the patterns of specialised (inpatient and specialised outpatient) psychiatric and somatic healthcare use, 3 years before and after a suicide attempt, differ between refugees and the Swedish-born individuals in Sweden. Additionally, we aimed to explore if specialised healthcare use differed among refugee suicide attempters according to their sex, age, education or receipt of disability pension.

METHODS

All refugees and Swedish-born individuals, 20-64 years of age, treated for suicide attempt in specialised healthcare during 2004-2013 (n = 85,771 suicide attempters, of which 4.5% refugees) were followed 3 years before and after (Y - 3 to Y + 3) the index suicide attempt (t0) regarding their specialised healthcare use. Annual adjusted prevalence with 95% confidence intervals (CIs) of specialised healthcare use were assessed by generalized estimating equations (GEE). Additionally, in analyses among the refugees, GEE models were stratified by sex, age, educational level and disability pension.

RESULTS

Compared to Swedish-born, refugees had lower prevalence rates of psychiatric and somatic healthcare use during the observation period. During Y + 1, 25% (95% CI 23-28%) refugees and 30% (95% CI 29-30%) Swedish-born used inpatient psychiatric healthcare. Among refugees, a higher specialised healthcare use was observed in disability pension recipients than non-recipients.

CONCLUSION

Refugees used less specialised healthcare, before and after a suicide attempt, relative to the Swedish-born. Strengthened cultural competence among healthcare professionals and better health literacy among the refugees may improve healthcare access in refugees.

Risk of suicide attempt and suicide in young adult refugees compared to their Swedish-born peers: a register-based cohort study

PURPOSE

Refugees, especially minors, who often have experienced traumatic events, are a vulnerable group regarding poor mental health. Little is known, however, of their risk of suicidal behaviour as young adults. We aimed to investigate the risk of suicidal behaviour for young adult refugees who migrated as minors. The moderating role of education and history of mental disorders in this association was also investigated.

METHODS

In this register linkage study, all 19-30-year-old Swedish-born (n = 1,149,855) and refugees (n = 51,098) residing in Sweden on December 31st, 2009 were included. The follow-up period covered 2010-2016. Cox models were used to calculate hazard ratios (HRs) with 95% confidence intervals (CIs). The multivariate models were adjusted for socio-demographic, labour market marginalisation and health-related factors.

RESULTS

Compared to Swedish-born, the risk of suicide attempt was lower for all refugees (HR 0.78, 95% CI 0.70-0.87), and accompanied refugee minors (HR 0.77, 95% CI 0.69-0.87), but estimates did not differ for unaccompanied refugee minors (HR 0.83, 95% CI 0.62-1.10). Low education and previous mental disorders increased the risk of suicide attempt in both refugees and Swedish-born, with lower excess risks in refugees. Findings for suicide were similar to those of suicide attempt.

CONCLUSION

Young adult refugees have a lower risk of suicidal behaviour than their Swedish-born peers, even if they have low educational level or have mental disorders. Young refugees who entered Sweden unaccompanied do not seem to be equally protected and need specific attention.

Mortality and major disease risk among migrants of the 1991-2001 Balkan wars to Sweden: A register-based cohort study

BACKGROUND

In recent decades, millions of refugees and migrants have fled wars and sought asylum in Europe. The aim of this study was to quantify the risk of mortality and major diseases among migrants during the 1991-2001 Balkan wars to Sweden in comparison to other European migrants to Sweden during the same period.

METHODS AND FINDINGS

We conducted a register-based cohort study of 104,770 migrants to Sweden from the former Yugoslavia during the Balkan wars and 147,430 migrants to Sweden from 24 other European countries during the same period (1991-2001). Inpatient and specialized outpatient diagnoses of cardiovascular disease (CVD), cancer, and psychiatric disorders were obtained from the Swedish National Patient Register and the Swedish Cancer Register, and mortality data from the Swedish Cause of Death Register. Adjusting for individual-level data on sociodemographic characteristics and emigration country smoking prevalence, we used Cox regressions to contrast risks of health outcomes for migrants of the Balkan wars and other European migrants. During an average of 12.26 years of follow-up, being a migrant of the Balkan wars was associated with an elevated risk of being diagnosed with CVD (HR 1.39, 95% CI 1.34-1.43, p < 0.001) and dying from CVD (HR 1.45, 95% CI 1.29-1.62, p < 0.001), as well as being diagnosed with cancer (HR 1.16, 95% CI 1.08-1.24, p < 0.001) and dying from cancer (HR 1.27, 95% CI 1.15-1.41, p < 0.001), compared to other European migrants. Being a migrant of the Balkan wars was also associated with a greater overall risk of being diagnosed with a psychiatric disorder (HR 1.19, 95% CI 1.14-1.23, p < 0.001), particularly post-traumatic stress disorder (HR 9.33, 95% CI 7.96-10.94, p < 0.001), while being associated with a reduced risk of suicide (HR 0.68, 95% CI 0.48-0.96, p = 0.030) and suicide attempt (HR 0.57, 95% CI 0.51-0.65, p < 0.001). Later time period of migration and not having any first-degree relatives in Sweden at the time of immigration were associated with greater increases in risk of CVD and psychiatric disorders. Limitations of the study included lack of individual-level information on health status and behaviors of migrants at the time of immigration.

CONCLUSIONS

Our findings indicate that migrants of the Balkan wars faced considerably elevated risks of major diseases and mortality in their first decade in Sweden compared to other European migrants. War migrants without family members in Sweden or with more recent immigration may be particularly vulnerable to adverse health outcomes. Results underscore that persons displaced by war are a vulnerable group in need of long-term health surveillance for psychiatric disorders and somatic disease.

Recruitment and Baseline Characteristics of Participants in the "Sanadak" Trial: A Self-Help App for Syrian Refugees with Post-traumatic Stress

Many Syrian refugees residing in Germany have been exposed to traumatizing events, while treatment options are scarce. Therefore, the self-help app “Sanadak” was developed to target post-traumatic stress in Syrian refugees. We aimed to inspect the recruitment and baseline characteristics of the participants in the trial, which is conducted to evaluate the app. Analyses were based on the recruitment sample (n = 170) and the trial sample (n = 133). Data were collected during structured face-to-face interviews in the Arabic language. Targeted outcomes included post-traumatic stress (primary; Post-traumatic Diagnostic Scale for DSM-5/PDS-5) and depressive symptoms, anxiety, resilience, among others (secondary). Recruited individuals were M = 32.8 (SD = 11.2, range = 18–65) years old; 38.8% were women. The average PDS-5 score was 23.6 (SD = 13.2) regarding trauma exposure, which was most frequently related to experiencing military- or combat-related events (32.9%). Moreover, 46.5% had major depression and 51.8% showed low resilience. Anxiety was present in 40.6% of the trial participants. Psychological distress was high in Syrian refugees residing in Germany, enrolled in a trial targeting post-traumatic stress. This underlines the need for intervention. Our results provide important figures on the mental health of a not well-studied population group in Germany.

Previous suicide attempt and subsequent risk of re-attempt and suicide: Are there differences in immigrant subgroups compared to Swedish-born individuals?

BACKGROUND

Studies investigating how suicide attempting refugees and non-refugee migrants differ from Swedish-born individuals in terms of re-attempts and suicide are missing. It remains unknown how mental disorders and labour market marginalization (LMM) impact on these associations.

METHODS

This longitudinal cohort study included Swedish residents aged 20-64 with suicide attempt in 2004-2012. In total, 42,684 individuals including 2017 refugees, and 2544 non-refugee migrants were included and followed until December 31, 2016. Risks of re-attempt and suicide were calculated as hazard ratios (HR) with 95% confidence intervals (CI), and adjusted for important confounders. Stratified analyses were to assess if mental disorders or LMM modified these associations.

RESULTS

In the adjusted models, refugees had an adjusted HR (aHR) of suicide re-attempt of 0.74 (CI: 0.67-0.81), and an aHR of 0.67 (CI: 0.53-0.86) for suicide death. These estimates were very similar to those of non-refugee migrants. Refugees and non-refugee migrants with suicide attempt had a lower prevalence of specialised health care due to mental disorders compared to Swedish-born attempters (48%, 44% and 61%, respectively). Mental disorders and LMM in terms of long-term sickness absence and disability pension increased the risk of re-attempt and suicide in all three groups.

LIMITATIONS

Only suicide attempts and mental disorders resulting in specialized in-and outpatient care were registered.

CONCLUSION

Migrants show considerably lower risks of re-attempt and suicide than Swedish-born individuals, with no differences between migrant groups. Despite vast differences in the prevalence of specific mental disorders, the role of mental disorders in the pathways to re-attempt and suicide does not appear to differ considerably between these groups.

Mental disorders and suicidal behavior in refugees and Swedish-born individuals: is the association affected by work disability?

BACKGROUND

Among potential pathways to suicidal behavior in individuals with mental disorders (MD), work disability (WD) may play an important role. We examined the role of WD in the relationship between MD and suicidal behavior in Swedish-born individuals and refugees.

METHODS

The study cohort consisted of 4,195,058 individuals aged 16-64, residing in Sweden in 2004-2005, whereof 163,160 refugees were followed during 2006-2013 with respect to suicidal behavior. Risk estimates were calculated as hazard ratios (HR) with 95% confidence intervals (CI). The reference groups comprised individuals with neither MD nor WD. WD factors (sickness absence (SA) and disability pension (DP)) were explored as potential modifiers and mediators.

RESULTS

In both Swedish-born and refugees, SA and DP were associated with an elevated risk of suicide attempt regardless of MD. In refugees, HRs for suicide attempt in long-term SA ranged from 2.96 (95% CI: 2.14-4.09) (no MD) to 6.23 (95% CI: 3.21-12.08) (MD). Similar associations were observed in Swedish-born. Elevated suicide attempt risks were also observed in DP. In Swedish-born individuals, there was a synergy effect between MD, and SA and DP regarding suicidal behavior. Both SA and DP were found to mediate the studied associations in Swedish-born, but not in refugees.

CONCLUSION

There is an effect modification and a mediating effect between mental disorders and WD for subsequent suicidal behavior in Swedish-born individuals. Also for refugees without MD, WD is a risk factor for subsequent suicidal behavior. Particularly for Swedish-born individuals with MD, information on WD is vital in a clinical suicide risk assessment.
