Definite and undetermined forensic diagnoses of suicide among immigrants in Sweden

A network frame offers a promising transdisciplinary tool for understanding complex health and health care system problems like suicide

As health and health care systems continue to face massive challenges from local to global well-being, understanding the processes that lead to improvement or deterioration in human health has embraced a broad range of forces from genes to national cultures. Despite the many efforts to deploy a common framework that captures diverse drivers at scale, the common missing element is the absence of a flexible mechanism that can guide research within and across levels. This hinders both the cumulation of knowledge and the development of a scientific foundation for multiplex interventions. However, studies across disciplines using a wide variety of methods and measures have converged on "connectedness" as crucial to understanding how factors operate in the health space. More formally, a focus on the critical role of the network structure and content of key elements and how they interact, rather than just on the elements themselves, offers both a generalized theory of active factors within levels and the potential to theorize interactions across levels. One critical contemporary health crisis, suicide, is deployed to illustrate the Network Embedded Symbiome Framework. The wide range of health and health care research where networks have been implicated supports its potential but also cautions against inevitable limits that will require creative theorizing and data harmonization to move forward.

Prevalence of Suicide in Immigrants/Refugees: A Systematic Review and Meta-Analysis

OBJECTIVE

In recent years, there has been an increase in immigrant populations worldwide. This study aims to present the global prevalence of suicide between immigrants and refugees as well as to report the prevalence of suicide ideation, suicide mortality, suicide attempts, and plan of suicide.

METHOD

Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA's) rules were used as a guide in the current research path. PubMed and EMBASE were targeted for the study until December 2019. After collecting the data, the number of events and sample size extracted for each study and also pooled odds ratio and confidence interval (CI) were used to investigate the suicide ratio among immigrants and refugees compared to the native population.

RESULTS

Fifty-one studies were included in the meta-analysis to investigate suicide prevalence or suicide odds ratio. The prevalence of suicidal ideation was 16% (CI: 0.12-0.20, I2 = 99.4%), for attempted suicide was 6% (CI: 0.05-0.08, I2 = 98.0%), and for suicide plan prevalence was 4% (CI: 0.00-0.08, I2 = 96.8%). The prevalence of suicidal ideation was 10% (CI: 0.04-0.17, I2 = 0.0%) in men and 17% (CI: 0.10-0.24, I2 = 96.8%) in women. The prevalence of attempted suicide was 1% (CI: 0.01-0.02, I2 = 0.0%) in men and 7% (CI: 0.03-0.10, I2 = 94.4%) in women. The odds ratio of suicide mortality among immigrants was 0.91 (CI: 0.90-0.93, p < 0.001; I2 = 97.6%) and for attempted suicide was 1.15 (CI: 1.10-1.20, p < 0.001; I2 = 92.0%). Begg's test (p = 0.933) (Egger test; p = 0.936) rejected publication bias.

CONCLUSION

Given the high prevalence of suicide, especially suicide ideation and suicide attempts in immigrants, increased attention needs to be paid to the mental health of this population.

Psychosis, migration and social environment: an age-and-gender controlled study

Purpose

Adverse social experiences are frequently invoked to explain the higher rate of psychosis among migrant groups. The aim of the present study was to establish the socio-environmental factors distinguishing migrant psychotic patients from autochthonous patients.

Subjects and method

We conducted a cross-sectional survey involving 341 migrant psychotic patients matched for age and gender with 341 autochthonous psychotic patients.

Results

Migrant patients lived more often with their parental family, were less often enrolled with a referral psychiatrist, presented a lower rate of employment, a lower percentage of alcohol misuse and of suicide attempts.

Discussion

Our findings add to the growing body of results showing that more attention needs to be focused on socio-environmental variables in psychosis research. However, several limitations have to be taken into account, particularly with regard to selection biases and age of onset of the psychotic illness.

Conclusion

Our results are compatible with the hypothesis that unemployment is a contributing factor in the risk for psychosis among migrant groups. Migrants’ families are an important keystone in the mental health care process of their sick relatives. Our service models need to be adapted with the aim to make the treatment easier for migrant patients.

Suicidal thoughts and behaviors and social isolation: A narrative review of the literature

BACKGROUND

Social isolation is one of the main risk factors associated with suicidal outcomes. The aim of this narrative review was to provide an overview on the link between social isolation and suicidal thoughts and behaviors.

METHODS

We used the PubMed database to identify relevant articles published until April 13, 2018. We focused on: (a) systematic reviews, meta-analyses, and narrative reviews; (b) original observational studies with large samples (N ≥ 500); and (c) qualitative studies. We included all relevant suicidal outcomes: suicidal ideation (SI), suicidal planning, non-suicidal self-injury, deliberate self-harm, suicide attempt (SA), and suicide.

RESULTS

The main social constructs associated with suicidal outcomes were marital status (being single, separated, divorced, or widowed) and living alone, social isolation, loneliness, alienation, and belongingness. We included 40 original observational studies, the majority of them performed on adolescents and/or young adults (k = 23, 57.5%). Both the objective condition (e.g., living alone) and the subjective feeling of being alone (i.e., loneliness) were strongly associated with suicidal outcomes, in particular with SA and SI. However, loneliness, which was investigated in most studies (k = 24, 60%), had a major impact on both SI and SA. These associations were transculturally consistent.

LIMITATIONS

Confounding factors can limit the weight of the results obtained in observational studies.

CONCLUSIONS

Data from the observational studies suggest that both objective social isolation and the subjective feeling of loneliness should be incorporated in the risk assessment of suicide. Interventional studies targeting social isolation for suicide prevention are needed.

Life Satisfaction Among Ethnic Minorities in Europe

Although life satisfaction (LS) of ethnic minorities can be significantly undermined by several psychological and material hardships, relatively few studies have examined this issue across Europe. The aim of the present study is to examine the impact of belonging to an ethnic minority group on LS, using data from the sixth wave of the European Social Survey (ESS6), carried out in 2012 in 29 countries ( N = 54,540). About 6.7% of all the participants in the ESS6 considered themselves belonging to an ethnic minority group. Our findings show that LS is lower for the ethnic minorities than for the majority not only in the pooled ESS6 sample but also in 19 European countries, most notably in Slovakia and in the Czech Republic. Multilevel analysis indicated that the negative impact of ethnic minority status on LS tended to be enhanced in ex-Communist countries as well as in countries with higher ethnic diversity. The findings of this study show clearly that policy makers of several European countries should focus on increasing social justice and solidarity, and providing ethnic minorities real opportunities to feel more integrated into society.

Assessment and treatment of asylum seekers after a suicide attempt: a comparative study of people registered at mental health services in a Swedish location

BACKGROUND

Even though asylum seekers are considered vulnerable to mental ill-health, knowledge of their suicidal behaviour is limited. The aim of this study was to improve our understanding of factors that influence the clinical assessment of asylum seekers who have attempted suicide compared to the assessment of non-asylum seekers.

METHODS

The study focused on 88 asylum seekers registered for suicide attempts in mental health services 2005-2009, who were matched for age and gender and compared with 88 suicide attempters with Swedish personal identity numbers. The medical records were analysed with a quantitative protocol, focusing on social risk and protective factors, health history, current clinical picture as well as the assessment procedure, diagnostics, patterns of treatment and follow-up in this clinical group. Data was analysed using the chi-square test, Fisher's exact probability test, and the Mann-Whitney U test.

RESULTS

As in earlier studies, asylum seekers were more traumatized, had different social risk factors and received different diagnoses than the controls. Asylum seekers were referred to less specialized follow-up after treatment, in spite of their health history and of previous and current clinical pictures indicating a similar or--in the case of the female asylum seekers--more serious mental health condition. Female asylum seekers also received more intense and prolonged in-patient treatment than female controls. Asylum seekers appeared to have social networks more often than the control group. However, there was less documentation of the social context, previous suicidal behaviour, and on suicide in the family and close environment of the asylum-seeking men. Information on suicidal intent was lacking in a majority of both groups. The time relation of the suicide attempt and the asylum process suggested the importance of the asylum decision, as well as the possible role of earlier mental health problems and premigration stress, for the suicidal behaviour.

CONCLUSIONS

The groups had different sets of risk factors and clinical pictures. There was a lack of early and thorough exploration of suicide intent for both groups, and of contextual and subjective factors for the asylum seekers. Differences in follow-up indicate unequal access to care.

Recent research on the mental health of immigrants to Sweden: a literature review

The arrival of large numbers of economic migrants and refugees has seen the Swedish immigrant population increase rapidly. Research has shown that immigrants may be more susceptible to mental disorders because of traumatic events prior to immigration and adverse circumstances in their new country. The aim of this literature review is to summarize and interpret recent research on the mental health of immigrants to Sweden.

METHODS

A systematic search for relevant literature in PubMed was performed on 13 February 2014. Relevant literature was limited to original research articles published between 1 January 1994 and 13 February 2014. Content relating to mental disorders and suicide was reviewed and summarized.

RESULTS

Nationwide studies showed increased risks of common mental disorders such as depression, as well as psychotic disorders, in immigrants to Sweden compared to native Swedes. However, the results are complex, with notable differences between different immigrant groups and between males and females. Risk of suicide was increased in some immigrant groups, but decreased in others. There has been little qualitative research on the mental health of immigrants and few intervention studies have targeted immigrants.

CONCLUSION

Immigrants to Sweden are a mixed group with differing, but often increased, risks of mental disorders. Targeted qualitative and intervention studies may facilitate efforts to develop and implement preventive methods for immigrants at high risk of mental ill health, and to tailor treatment to the specific needs of different immigrant groups.

Suicide among immigrants in Europe--a systematic literature review

BACKGROUND

Concerns about increased suicide risk among immigrants to European countries have been raised. We review the scientific literature on differences in suicide among immigrants compared with the majority populations in Europe's major immigration countries.

METHODS

We searched the databases PubMed and PsycINFO for peer-reviewed epidemiological studies published in 1990-2011, which compared suicide risks of adult immigrant groups with the risks of the majority population in European countries. Hits were screened by two researchers.

RESULTS

We included 24 studies in the review. No generalizable pattern of suicide among immigrants was found. Immigrants from countries in which suicide risks are particularly high, i.e. countries in Northern and Eastern Europe, experienced higher suicide rates relative to groups without migration background. Gender and age differences were observed. Young female immigrants from Turkey, East Africa and South Asia are a risk group.

CONCLUSION

Immigrants 'bring along' their suicide risk, at least for the initial period they spend in the immigration country. Health-care planners and providers need to be aware of this 'imported risks'. However, most immigrant groups do not have an increased suicide risk relative to the local-born population; some may even experience substantially lower risks.

Characteristics of immigrant suicide completers in a sample of suicide victims from Greece

BACKGROUND

Immigrants have higher rates of suicidal behaviour in comparison to the indigenous population.

AIMS

To describe the characteristics of foreign nationality suicide completers and search for differences between them and native Greeks. This is the first study focused on immigrant suicide victims in Greece.

METHODS

Data were collected for all recorded cases of completed suicide for the two-year period November 2007 to October 2009 at the Athens Department of Forensic Medicine, the largest, by far, of its kind in Greece covering approximately 35% of the country's population. The material was collected using the method of psychological autopsy as well as from the victims' forensic records.

RESULTS

Nearly 10% of Greece's 11 million population are of foreign nationality. Approximately half of them live in Athens and its suburbs, an area where 35% of Greece's population lives. In our sample, 15.8% of the suicide victims were of foreign nationality (53 cases): 41 men (77.4%) and 12 women (22.6%). Higher suicide rates were found for citizens of Kuwaiti (9.1%), Somali (6.7%) and Afghan (0.9%) nationality (immigrant communities with very few members); the lower suicide rates were for individuals of Egyptian (0.01%), Ukrainian (0.01%) and Albanian (0.006%) nationality (the Albanian immigrant community is the largest in Greece). In comparison to their Greek counterparts, immigrant victims were younger (mean age 38.7 vs 54.9 years, p < .001) more often unemployed (p = .007) and with a history of alcohol abuse (p < .001). The main suicide method used by immigrants was hanging (p < .001) while for Greeks it was jumping from a height.

CONCLUSIONS

Individuals who belong to small national communities seem to have the highest risk of dying by suicide. Immigrant suicide victims differ from the indigenous population in several parameters. Our data could help define the most vulnerable of them and apply more effective suicide prevention strategies.

An Exploration into the Impact of the Resettlement Experience, Traditional Health Beliefs and Customs on Mental Ill‐Health and Suicide Rates in the Ethiopian Community in London

Forced migration and the resettlement experience combine to produce a set of social, cultural, economic and psychological challenges for forced migrants which may affect integration, mental and physical health, and access to health and social care. There is very little research on the resettlement experience of Ethiopian forced migrants in London, particularly on causes of mental illness and access to mental health care. Few studies have examined whether and how traditional beliefs and customs affect the experiences of this group in health care. The paper reports on a pilot study consisting of interviews with an Ethiopian priest, community leaders and Ethiopians working in the community health sector with the aims of improving our understanding of the issues, and to inform further study. Initial analysis suggests that this group faces multiple forms of disadvantage which affect mental health. A further interesting dynamic is the relation between lack of ‘help seeking behaviour’, due to cultural expectations and norms, and lack of access and engagement with Western treatments. Religious mechanisms and activities were also reported as bolstering coping mechanisms. Perhaps most significant was concern about the increasing suicide rate among this group, many respondents suggesting a direct causal link between suicide and maladjustment in exile.

Suicide risk among persons with foreign background in Denmark

There is a dearth of knowledge about factors correlated with suicide risk among minority groups in Western societies. In the present study we compared suicide risk among persons with foreign background with that of the majority population to determine whether certain minority groups are at a particular risk for suicide, as well as to illuminate gender differences herein. Suicide risk was generally higher among persons with foreign background compared with the majority population and the risk was highest among Nordic-born persons. Overall, suicide risk was significantly lower among Asian-born persons; however, there were gender differences in correlations between ethnicity and suicide risk.

Increasing seasonality of suicide in Australia 1970-1999

Previous studies have found that rates of suicide have a distinct annual rhythm with a peak in spring. Two recent European studies, however, have found that the amplitude of this rhythm has decreased over time. The purpose of this study was to examine whether such effects are found in Australia. Australian Bureau of Statistics data on all suicides in Australia 1970-1999 were analysed by spectral analysis. We found that suicide, violent suicide and suicide by males are seasonal and that the seasonal amplitude has increased over time. Males who use violent methods determine the seasonal effect. These results support previous findings that suicide and particularly violent suicide have a characteristic seasonal rhythm. However, the progressive increase in the amplitude of this rhythm over time in Australia is in direct contrast to other European findings. We suggest that this may be related to differences in patterns of anti-depressant use and also the effect of migration on the number of seasonally vulnerable individuals in Australia.

Ethnicity, self reported psychiatric illness, and intake of psychotropic drugs in five ethnic groups in Sweden

STUDY OBJECTIVE

This study hypothesises that the presumed increased risk of self reported longstanding psychiatric illness and intake of psychotropic drugs among Iranian, Chilean, Turkish, and Kurdish adults, when these groups are compared with Polish adults, can be explained by living alone, poor acculturation, unemployment, and low sense of coherence.

DESIGN

Data from a national sample of immigrants/refugees, who were between the ages of 20-44 years old, upon their arrival in Sweden between 1980 and 1989. Unconditional logistic regression was used in the statistical modelling.

SETTING

Sweden.

PARTICIPANTS

1059 female and 921 male migrants from Iran, Chile, Turkey, Kurdistan and Poland and a random sample of 3001 Swedes, all between the ages of 27-60 years, were interviewed in 1996 by Statistics Sweden.

MAIN RESULTS

Compared with Swedes, all immigrants had an increased risk of self reported longstanding psychiatric illness and for intake of psychotropic drugs, with results for the Kurds being non-significant. Compared with Poles, Iranian and Chilean migrants had an increased risk of psychiatric illness, when seen in relation to a model in which adjustment was made for sex and age. The difference became non-significant for Chileans when marital status was taken into account. After including civil status and knowledge of the Swedish language, the increased risks for intake of psychotropic drugs for Chileans and Iranians disappeared. Living alone, poor knowledge of the Swedish language, non-employment, and low sense of coherence were strong risk factors for self reported longstanding psychiatric illness and for intake of psychotropic drugs. Iranian, Chilean, Turkish and Kurdish immigrants more frequently reported living in segregated neighbourhoods and having a greater desire to leave Sweden than their Polish counterparts.

CONCLUSION

Evidence substantiates a strong association between ethnicity and self reported longstanding psychiatric illness, as well as intake of psychotropic drugs. This association is weakened by marital status, acculturation status, employment status, and sense of coherence.

Impact of ethnicity, violence and acculturation on displaced migrants: psychological distress and psychosomatic complaints among refugees in Sweden

This study uses data collected in 1996 by the Swedish National Board of Health and Welfare. By means of interviews with 1980 foreign-born immigrants, an attempt was made to determine the impact of a) migration status (country of birth/ethnicity), b) exposure to violence, c) Antonovsky's sense of coherence, d) acculturation status (knowledge of Swedish), e) sense of control over one's life, f) economic difficulties, and g) education, both on psychological distress (using General Health Questionnaire 12) and psychosomatic complaints (daytime fatigue, sleeping difficulties, and headache/migraine). Iranians and Chileans (age-adjusted) were at great risk for psychological distress as compared with Poles, whereas Turks and Kurds exhibited no such risk. When the independent factors were included in the model, the migration status effect decreased to insignificance (with the exception of Iranian men). A low sense of coherence, poor acculturation (men only), poor sense of control, and economic difficulties were strongly associated with the outcomes, generally accounting for a convincing link between migration status and psychological distress. Furthermore, a low sense of coherence, poor acculturation (men only), poor sense of control, and economic difficulties in exile seemed to be stronger risk factors for psychological distress in this group than exposure to violence before migration.

On the role of neurobiological and genetic factors in the etiology and pathogenesis of suicidal behavior among immigrants

Immigrants have higher rates of suicidal behavior than those in their countries of origin and their new countries. Immigration is a stressful life event which may lead to depression and suicidal behavior. Depressive disorders and suicidal behavior have a firm neurobiological and genetic basis. The author suggests that most immigrants who exhibit suicidal behavior in the new country had suicidal tendencies, and/or some degree of depression, and/or certain maladaptive personality traits in their countries of origin. The paper emphasizes the role of genetic and neurobiological factors in the human response to stressful events.

Urban and rural suicide differentials in migrants and the Australian-born, New South Wales, Australia 1985--1994

We estimated risk of suicide in adults in New South Wales (NSW) by sex, country of birth and rural/urban residence, after adjusting for age; we also examined youth suicide (age 15-24 years). The study population was the entire population of NSW, Australia, aged > or =15 years during the period 1985-1994. Poisson regression was used to examine the relationship between predictor variables and the risk of suicide, with the focus on migrant status and area of residence. A significantly higher risk of suicide was found in male migrants from Northern Europe and Eastern Europe/former USSR, compared to Australian-born males; a significantly lower suicide risk occurred in males from Southern Europe, the Middle East and Asia. In female migrants, those from UK/Eire, Northern Europe, Eastern Europe/former USSR and New Zealand exhibited a significantly higher risk of suicide compared to Australian-born females. A significantly lower risk of suicide occurred in females from the Middle East. Male migrants overall were at significantly lower risk of suicide than the Australian-born, while female migrants overall had a significantly higher risk of suicide than Australian-born females. Among migrant males overall, the rural-urban suicide risk differential was significantly higher for those living in non-metropolitan areas (RR = 1.9; 95% CI: 1.7-2.1). Suicide risk was significantly higher in non-metropolitan male immigrants from the UK/Eire (RR = 1.4; 95% CI: 1.1-1.7), Southern Europe (RR = 1.7; 95% CI: 1.2-2.4), Northern/Western Europe (1.5; 95% CI: 1.2-1.9), the Middle East (RR = 3.8; 95% CI: 1.9-7.8), New Zealand (RR = 1.4; 95% CI: 1.0-1.8) and 'other' (RR = 2.6; 95% CI: 1.9-3.5), when compared to their urban counterparts. There was no statistically significant difference in suicide risk between rural and urban Australian-born males. For female suicide, significantly lower risk was found in female immigrants living in non-metropolitan areas who were from Northern/Western Europe (RR = 0.7; 95% CI: 0.4-0.96), as well as the Australian-born (RR = 0.7; 95% CI: 0.6-0.8), when compared to their urban counterparts. The non-metropolitan/metropolitan relative risk for suicide in female migrants overall was not significantly different from one. Among male youth there was a significantly higher suicide risk in non-metropolitan areas, with a relative risk estimate of 1.4 for Australian-born youth (95% CI: 1.2-1.5) and 1.7 for migrant youth (95% CI: 1.2-2.4), when compared with metropolitan counterparts. We conclude that suicide among migrant males living in non-metropolitan areas accounts for most of the excess of male suicide in rural NSW, and the significantly lower risk of suicide for non-metropolitan Australian-born women does not apply to migrant women.

Violent mortality patterns in immigrants in Israel (1990-95)

Since 1989, a large number of immigrants, mostly from the former Soviet Union, have arrived in Israel, increasing the local population (c. 5 million) by 700,000. The morbidity and mortality of this immigrant population have been the concern of many investigations. In the present study we examine the mortality pattern of a sample of 1,000 immigrants, whose deaths occurred during the years 1990-95 and were examined at the L. Greenberg (National) Institute of Forensic Medicine. The sample was divided into two subgroups, natural and unnatural, according to manner of death. Seventy-five per cent of the victims in the violent death subgroup were males with a mean age of 44.6 (SD 17.3) years, while the females of the same category were 52.7 years old on average (SD 19.9). The age distribution of the whole sample showed peaks in the 25-34-year-old group for males and the 35-44-year-old group for females. The most frequent causes of death were accident (44.1%), suicide (12.6%) and homicide (7%). In 5% of cases the cause of death could not be determined. The pattern of mortality from violent causes in the immigrant population differed from that of the country of origin in all parameters. The incidence of unnatural death in immigrants resembled the local pattern in Israel, and was significantly lower than that of their homeland.

Suicide in urban New South Wales, Australia 1985-1994: socio-economic and migrant interactions

Variation of suicide with socio-economic status (SES) in urban NSW (Australia) during 1985-1994, by sex and country or region of birth, was examined using Poisson regression analysis of vital statistics and population data (age >¿ approximately 15 yr). Quintiles of SES were defined by municipality of residence and comparisons of suicide by SES were adjusted for age and country (or region) of birth (COB), and examined by COB. Risk of suicide in females was 28% that of males for all adults and 21% for youth (age 15-24 yr). Suicide risk was lower in males from southern Europe, Middle East and Asia, and higher in northern and eastern European males, compared to the Australian-born. Risks for suicide increased significantly with decreasing SES in males, but not in females. The relationship of male suicide and SES was stronger when controlled for COB. For males, the relative risk of suicide, adjusted for age and COB, was 66% higher in the lowest SES quintile compared to the highest quintile. and 39% higher for youth (age 15-24 yr). For male suicide, the population attributable fraction for SES (less than the highest quintile) was 27%. Analysis of SES differentials in male suicide according to COB indicated a significant inverse suicide gradient in relation to SES for the Australian-born and those born in New Zealand and the United Kingdom or Eire, but not in non-English speaking COB groups, except for Asia. For Australian-born males, suicide risk was 71% higher in the lowest SES group (compared to the highest), adjusted for age. These findings indicate that SES plays an important role in male suicide rates among the Australian-born and migrants from English-speaking countries and Asia, and among youth; but not in female suicide, nor suicide in most non-English speaking migrant groups. Reduction in SES differentials through economic and social policies may reduce male suicide in lower SES groups and should be seen to be at least as important as individual level interventions.

Review of social epidemiologic research on migrants' health: findings, methodological cautions, and theoretical perspectives

The phenomenon of world-wide immigration and migration has major implications for the health of the migrants in addition to its impact upon social and other service providers. Studies of migrants that utilize social epidemiologic methods fall within the traditional boundaries of descriptive and analytic approaches; this article reviews some of the studies that exemplify these approaches. It then suggests specific methodological issues and cautions pertaining to research on migrants and provides a theoretical model for organizing the diverse research studies that have been conducted. By stimulating discussion regarding social epidemiologic research on migrants' health, this model is intended to serve as a compass point for future research and needed interventions.

Suicidal behavior after severe trauma. Part 1: PTSD diagnoses, psychiatric comorbidity, and assessments of suicidal behavior

The study comprises 149 refugees from various countries, reporting exposure to severe traumata, who were referred for psychiatric diagnosis and assessment of suicide risk. The stressors reported comprised both personal experience of and/or forced witnessing of combat atrocities (including explosions or missile impacts in urban areas), imprisonment (including isolation), torture and inflicted pain, sexual violence, witnessing others' suicide, and of summary and/or mock executions. Posttraumatic stress disorder (PTSD) was diagnosed in 79% of all cases, other psychiatric illness in 16% and no mental pathology in 5%. The prevalence of suicidal behavior was significantly greater among refugees with principal PTSD diagnoses than among the remainder. PTSD patients with depression comorbidity reported higher frequency of suicidal thoughts; PTSD nondepressive patients manifested increased frequency of suicide attempts.

Suicidal behavior after severe trauma. Part 2: The association between methods of torture and of suicidal ideation in posttraumatic stress disorder

The study reports on 65 refugees with diagnoses of posttraumatic stress disorder (PTSD) and manifest suicidal behavior (40% had suicide attempts; 29% detailed suicide plan; 31% recurrent suicidal thoughts). Our hypothesis was that the predominant kind of stressful experience in PTSD patients might be reflected in their choice of method when pondering or attempting suicide. Relationships were found to exist between the main stressors and the respective subjects' preference for suicide method. Particularly among PTSD patients with a history of torture, an association was found between the torture methods that the victim had been exposed to, and the suicide method used in ideation or attempts. Blunt force applied to the head and body was associated with jumping from a height or in front of trains, water torture with drowning, or sharp force torture with methods involving self-inflicted stabbing or cutting. Relationships between main stressors and content of suicidal ideation are discussed.

Health and socioeconomic indicators in psychiatric catchment areas with divergent suicide rates

Differences found in the incidence of suicide between the psychiatric catchment areas of the Karolinska Hospital in Stockholm were investigated in relation to health and socioeconomic indicators during the study period 1990-1994. The hypothesis of the study was that negative socioeconomic indicators and psychosocial and health indicators denoting less favourable socioeconomic status may negatively influence the suicide rate of the demographic units in this cross-sectional study. The incidence of suicide between the areas was significantly different and increasingly divergent in the last year of the study period. The area with a higher proportion of suicides had also an increased proportion of individuals who retired early, lower life expectancy at birth, higher non-employment, lesser income among the employed, less public expenditure for education, less proportion of home ownership, and a higher proportion of persons bound to one-room dwellings. Disregarding the influence of ethnicity (there were no statistically significant differences on immigrants' suicide between the areas) as well as in the availability of psychiatric care (assuming that similar quality of psychiatric care was provided by both sectors), or other demographic indices commonly shared by the areas, the possibility of strong effects of unfavourable health and socioeconomic indices appeared relevant for the explantation of an increased incidence of suicide. The findings provide new empirical contradiction to the socioeconomic hypothesis of the incidence of suicide, which postulated that populations with higher socioeconomic status may have increased suicide rates.

Social psychological variables in populations contrasted by income and suicide rate: Durkheim revisited

The ten richest and ten poorest municipalities of Sweden were investigated with respect to national statistics to assess the relationship between suicide incidence, discrete social psychological variables associated with welfare admittance among the elderly, and income of municipality. The relative frequency of suicide was 1.6 times greater for Swedes from the low-income municipalities than for those from the high-income ones. The group of municipalities with the highest suicide rate had a significantly higher proportion of older people in need of municipal social assistance at their homes and also a significantly higher proportion of elderly living in municipality-managed 'service-homes.' The findings replicate earlier investigations and suggest social psychological indicators denoting less favourable economic and social resources are also associated with both an increased suicide rate and a decreased county or municipal income. Some theoretical issues of the socioeconomic and of the external restraint hypotheses of the incidence of suicide, contradicted by the present findings as well as of Durkheim's hypothesis of social control are discussed. Further, we suggest the consideration of negative socioeconomic conditions as a risk factor amid psychiatric clinical assessments of risk for suicidal behaviour.

Psychiatric health, ethnicity and socioeconomic factors among suicides in Stockholm

The suicide statistics for two high-income areas and two low-income areas of Stockholm county, with, respectively, low and high proportions of immigrant residents, were compared on health and socioeconomic factors to ascertain whether differences in such indicators might explain the overrepresentation of immigrants previously found by us in cases of definite and undetermined suicide. The findings can be summarised as follows. (1) The suicide rate was higher in the low-income areas, irrespective of ethnicity, and highest in the immigrant population of the low-income areas which accounted for 82% of all immigrants in the areas studied. (2) The suicide rate was inversely correlated with the respective figures for mean municipality-income indices. (3) Over the 4-yr. study period, the annual suicide rate increased among immigrants and decreased among native Swedes. (4) Of all categories investigated, immigrants from the low-income areas were characterised by the highest suicide rate (39 per 100,000) and the lowest mean annual income among the suicide victims (77.7), and native Swedes from the high-income areas by the lowest suicide rate (16.2) and the highest mean income (254.1). (5) The low-income areas manifested also lower mean duration of hospitalisation in primary care and psychiatric facilities, although the frequency of psychiatric consultations, was higher in low- than in high-income areas. Interrelations among low income, immigrant status, and poor benefit of psychiatric care suggest that proneness to suicidal behaviour among immigrants may have a social psychiatric explanation.

A cross-cultural breakdown of Swedish suicide

In this cross-cultural, nation-wide study including all immigrant groups in Sweden, over 10,000 suicides and undetermined cases occurring during the period 1987-1991 were analysed. Diagnoses of the underlying causes of death were classified according to ICD-9, all of the alternatives E950-E959 and E980-E989 being selected. Definite and overall suicide rates were estimated for each immigrant group represented. We found an overrepresentation of immigrants in the Swedish suicide statistics nation-wide. A total of 15 countries (60% of the immigrant population) manifested more observed than expected suicides and undetermined cases. This overrepresentation was statistically significant among immigrants from Russia, Finland, Germany, Denmark and Norway (the immigrant population of these countries represents nearly 50% of the total population of immigrants in Sweden). Other nationalities with an increased suicide incidence were from Poland, Hungary, Czechoslovakia, Austria, Korea, The Netherlands, France, Spain and Uruguay. The risk of an immigrant dying of a cause related to suicide was found to be 1.5 times higher than that for a native Swede. Furthermore, the increased suicide rates observed among the immigrant groups in Sweden were found to be higher than in the respective countries of origin for 90% of the nationalities investigated, including those characterized by a relatively high refugee flow to Sweden, the rank order being generally the same both in the countries of origin and in Sweden. The immigrant groups with the highest suicide rates in our study were from Russia, Finland and Hungary. Suggestions are made concerning the possible involvement of underlying cultural, anthropological and genetic factors in this phenomenon.

The influence of ethnicity and social and demographic factors on Swedish suicide rates. A four year follow-up study

The aim of this follow-up study, based on individual data, was to analyse the influence of ethnicity and other demographic and social factors on suicide rates between 1986 and 1989 for the Swedish population according to the 1985 census. The data were analysed by sex and age using a Poisson regression model. During the study period there were 8,310 cases of suicide and undetermined death. The main finding in this study was that ethnicity, defined as being foreign-born, was a significant risk factor for suicide in both sexes and in all age groups except for males aged 30 to 49 years. Not being married was a significant risk factor in all age groups for both males and females. Form of tenure, i.e. living in rented flats, was a significant risk factor for suicide in middle-aged males and females, while over-crowding was a risk factor for middle-aged males and for the over 50's of both sexes. As ethnicity, defined as foreign-born, was an important variable related to suicide, the association between different ethnic groups and suicide will be evaluated in forthcoming studies.

Social psychological indicators associated with the suicide rate: replying to the socioeconomic hypothesis

The Swedish counties manifesting the highest suicide rate, were investigated with regard to social psychological (acknowledgement of social assistance) and socioeconomic indicators (county income, and percentage of population in the lowest and highest income categories). Among these counties, were found the highest percentages of people in the lowest income class and also the highest percentage of households admitting social help. Gotland, having the highest suicide rate among the 24 counties of Sweden, was also the poorest, and in addition exhibited the highest percentage of persons in the lowest income class and the fewest in the highest income class. The findings challenge the socioeconomic hypothesis and suggest anew an association between social psychological strain, low income, and increased suicide rate.

Suicide among foreign-born minorities and Native Swedes: an epidemiological follow-up study of a defined population

The increasing number of immigrants in Sweden during the past four decades has brought the health of ethnic groups into focus. The purpose of this study was to analyse the influence of ethnicity, age, sex, marital status and date of immigration on suicide rates. The study population consisted of all individuals over 15 years of age, N = 6,725,274, from the Swedish census of 1985 and is based on individual data. Suicides and undetermined deaths, during the follow-up period 1986-1989, were taken from the central Cause of Death Register. Ethnicity, defined as being foreign-born, was a risk factor for suicide for both men and women with risk ratios of 1.21 (1.11-1.31) and 1.36 (1.21-1.53), respectively, with control for age and marital status. Being unmarried was also a risk factor for both males and females with risk ratios from 1.26 to 5.55 in different age groups. The highest risk ratios for suicide in Sweden, adjusted for age, were found among males born in Russia and Finland. They also showed higher suicide risks than in their countries of birth. Females born in Hungary, Russia, Finland and Poland all had high risks of committing suicide in Sweden and they also had higher risks than in their countries of birth. Further, being of male sex, aged 45-54 or 75 and older, and born in Eastern Europe or Finland were significant risk factors for suicide. The same was true for those who had immigrated to Sweden in 1967 or earlier and were born in Finland, Eastern Europe or in non-European countries. These findings are of great importance for primary health care and psychiatric care planning.

Social psychological vs socioeconomic hypotheses on the epidemiology of suicide: an empirical study

In a recent analysis of the suicide statistics of two areas of Stockholm of contrasting demographic and socioeconomic status, we found the suicide rate higher in the low-income area. In the present study, the suicide rate of the richest and poorest countries of Sweden were compared to test whether the negative correlation previously found locally between average income in the country and incidence of suicide, also exists in a nationwide extrapolation. The poorest county of Sweden, Berg, manifested an increased suicide rate of 46.2 per 100,000 population [Ratio observed/ expected (O/E) 2.3], whereas the richest, Danderyd, had a rate four times lower (10.8; Ratio O/E, 0.5), being also lower than the Swedish mean suicide rate of 17.2. The findings do not support the socioeconomic hypothesis on incidence of suicide, according to which an increased suicide rate is expected to be observed in demographic units with increased income or economic output.

Pathoanatomic findings and blood alcohol analysis at autopsy (BAC) in forensic diagnoses of undetermined suicide. A cross-cultural study

In Sweden, ca. 25% of unnatural deaths ascribed to self-inflicted injury are finally recorded as 'undetermined suicide' (abbreviated UMSA), i.e. the forensic pathologist has not been able to establish whether the fatality was an accident or a suicide. In the present study, a series of UMSA cases was investigated with the aims to study the impact of immigrant status, and alcohol abuse on the occurrence of this forensic diagnosis on the mode of death. The alcohol issue was addressed by focusing on blood alcohol concentrations at autopsy (BAC) and post mortem signs of alcohol-related organ pathology. The results can be summarised as follows: Positive BAC occurred at an equal rate in the UMSA group and in definite suicides, i.e. about 45%. Among non-Swedish UMSA victims positive BAC was more common (50%) than among the Swedish (41%), whereas no difference was found in the definite suicide group. The level of BAC at autopsy was significantly higher in Finnish immigrants than in other ethnic groups. Organic signs of chronic alcohol abuse were found in 13 of 40 cases testing positive for BAC; thus, presence of alcohol at autopsy may reflect incidental intake rather than habitual overconsumption.
