Influence of social and material individual and area deprivation on suicide mortality among 2.7 million Canadians: a prospective study

Role of individual deprivation and community-level deprivation on suicidal behaviors: Insights from the UK Biobank study

Introduction

This study aimed to investigate the impact of individual- and community-level deprivation on suicidal behaviors among community members.

Methods

Data from 350,884 UK Biobank participants were employed to construct an individual deprivation index. Absolute poverty was defined as a pre-tax annual household income below ₤18,000. Predictors for absolute poverty incorporated variables such as sex, ethnicity, type of accommodation, tenure status, number of vehicles owned, educational qualifications, current employment status, and subjective health rating. The individual deprivation index was constructed using a logistic regression model to predict absolute poverty. Townsend Deprivation Index (TDI) was employed to represent community-level deprivation. The associations between the individual deprivation index, TDI, and suicidal behaviors were examined through multivariate linear regression. Interaction analyses were conducted to investigate effect modification.

Results

The logistic regression model demonstrated high predictive accuracy for absolute poverty (area under the receiver operating curve = 0.840). The associations between individual deprivation index and suicidal behaviors were observed to be more substantial than those between TDI and suicidal behaviors. A positive interaction between the individual deprivation index and TDI was detected, indicating an amplifying effect of community-level deprivation on the impact of individual-level deprivation on suicidal behaviors.

Conclusion

Our study successfully constructed a comprehensive individual deprivation index that could be applied widely to measure individual-level deprivation. Our findings revealed that individual-level deprivation and community-level deprivation have a synergistic effect on suicidal behaviors, underscoring the importance of multilevel interventions in suicide prevention.

Self-harm and rurality in Canada: an analysis of hospitalization data from 2015 to 2019

PURPOSE

The incidence of self-harm is an important indicator in suicide surveillance and a target outcome for suicide prevention. Self-harm rates vary by geographic location and rurality appears to be a risk factor. The objectives of this study were to estimate rates of self-harm hospitalization in Canada over a 5-year period by sex and age group, and examine relationships between self-harm and rurality.

METHODS

Hospitalizations related to self-harm were identified in a national dataset (the Discharge Abstract Database) for all patients aged 10 years or older who were discharged from hospital between 2015 and 2019. Self-harm hospitalization rates were calculated and stratified by year, sex, age group, and level of rurality, as measured using the Index of Remoteness. A Poisson regression was fit to estimate rate ratios for the levels of rurality.

RESULTS

Rates of self-harm hospitalization were higher for females than males across all levels of rurality and increased with each level for both sexes, except for among young males. The widest rural-to-urban disparities were observed for the 10-19 and 20-34-year old age groups. Females aged 10-19 in very remote areas had the highest self-harm hospitalization rate.

CONCLUSION

The rate of self-harm hospitalization in Canada varied by sex, age group, and level of rurality. Clinical and community-based interventions for self-harm, such as safety planning and increased access to mental health services, should be tailored to the differential risks across geographic contexts.

Detection of Suicide Clusters using Small-Area Geographic Data from the Virginia Violent Death Reporting System, 2010 - 2015

Introduction

From 1999 to 2020, the suicide rate in Virginia increased from 13.1 to 15.9 per 100,000 persons aged 10 years and older. Few studies have examined spatial patterns of suicide geographies smaller than the county level.

Methods

We analyzed data from suicide decedents aged ≥10 years from 2010 through 2015 in the Virginia Violent Death Reporting System. We identified spatial clusters of high suicide rates using spatially adaptive filtering with standardized mortality ratio (SMR) significantly higher than the state SMR (p < 0.001). We compared demographic characteristics, method of injury, and suicide circumstances of decedents within each cluster to decedents outside any cluster.

Results

We identified 13 high-risk suicide clusters (SMR between 1.7 and 2.0). Suicide decedents in the clusters were more likely to be older (40+ years), non-Hispanic white, widowed/divorced/separated, and less likely to have certain precipitating suicide circumstances than decedents outside the clusters. Suicide by firearm was more common in four clusters, and suicide by poisoning was more common in two clusters compared to the rest of the state.

Conclusions

There are important differences between geographic clusters of suicide in Virginia. These results suggest that place-specific risk factors for suicide may be relevant for targeted suicide prevention.

The differential impacts of social deprivation and social fragmentation on suicides: A lesson from Hong Kong

INTRODUCTION

Little research has conducted to examine the association between social deprivation and social fragmentation, overall and method-specific suicide risk, and how these associations may change over time. This study investigated the association between social deprivation and social fragmentation with overall and method-specific suicide in Hong Kong from 1999 to 2018.

METHODS

Suicide death data of each small tertiary planning unit (STPU) was obtained from the Census and Statistics Department of Hong Kong. Socio-economic characteristics in STPU level were obtained from Census and Bi-census. Exploratory principal component analysis was used to construct the social deprivation (SDI) and social fragmentation indices (SFI) based on the socio-economic characteristics. Bayesian hierarchical modelling was conducted to explore the association between SDI and SFI with overall and method-specific suicide over time, controlling for population density and male-to-female ratio.

RESULTS

Higher risk of suicide was generally observed around Kowloon Peninsula and some parts in the Northern, Northwestern and Southwestern areas depending on methods. The effect of SDI and SFI on suicide risk varied by years and methods. In 2014-2018, for every 10% increase in SDI, the suicide risk for overall, jumping, hanging, and charcoal burning elevated by 22% (95%Crl = 10%-37%), 26% (95%Crl = 12%-41%), 31% (95%Crl = 14%-51%), and 21% (95%Crl = 4%-42%) respectively.

CONCLUSION

Spatial variations and effects of SDI and SFI on overall and method-specific suicide risks varied by different periods. SDI was observed to be a stronger factor in the recent years. Situations should be monitored, and interventions should be implemented and adjusted accordingly to the changes.

Suicidal ideation and social integration in three Canadian provinces: The importance of social support and community belonging

Extending recent developments in the neo-Durkheimian analysis of suicidality as an indicator of social pathology, this paper analyses individual level survey data on suicidal ideation, perceptions of social support, and the sense of belonging from three Canadian provinces drawn from the Canadian Community Health Survey (2015-16). We ask whether or not social support and a sense of belonging affect suicide ideation differently. In answering this question, we pay attention to both subjective and objective indicators of integration, and how subjective indicators independently affect suicide ideation. Results show that a higher level of social support had the largest effect on suicidal ideation and that the effect of a sense of belonging disappeared when measures of social support are accounted for. These findings are consistent with Durkheim's general theory of suicide and previous studies on mental health, highlighting the importance of regular, proximate social interaction as a prophylactic against suicidality.

Risk of suicide death in psychiatric patients according to the level of continuity of care and area deprivation: A population-based nested case-control study

Continuity of care and area deprivation have been implicated as possible risk factors of suicide in psychiatric patients. This nested case-control study aimed to examine the association between continuity of care and area deprivation and suicide death in patients with psychiatric disorders. Data were collected from the Korean National Health Insurance Service National Sample Cohort, 2003-2013. The subjects were 974 patients with psychiatric disorders who completed suicides. Each case was compared to three control cases with propensity score matching by gender, age, and follow-up period with incidence density sampling, comprising the final control group of 2,922 living patients. Hazard ratios (HR) for suicide risk considering continuity of care and area deprivation were analysed using a multiple conditional logistic regression. The average follow-up periods between the case and control groups were not statistically different (case: 277.6 weeks, control: 271.4 weeks, p = .245). Both poor continuity of care and higher area deprivation proved to be associated with increased risk of suicide (poor continuity of care; adjusted HR [AHR]: 3.38, 95% confidence intervals [CI]: 2.58-4.43, highest area deprivation; AHR: 1.93, 95% CI: 1.53-2.44). Poor continuity of care combined with highest area deprivation showed a negative synergistic effect on a highly increased risk of suicide (AHR: 2.88, 95% CI: 1.45-5.74). Age was effect modified between suicide risk and poor continuity of care as well as suicide risk and higher area deprivation. A strong patient-provider relationship with good continuity of care may lead to a lower possibility of suicide in psychiatric patients. Moreover, improving community capacity for suicide prevention as well as appropriate postvention should be addressed.

Prevalence and Associated Risk Factors of Suicidal Ideation Among Brazilian Pregnant Women: A Population-Based Study

BACKGROUND

Suicide is a leading cause of death during the perinatal period in high-income countries (HIC). There remains a lack of population-based studies about suicidal ideation (SI) during pregnancy among low and middle income countries (LMIC).

OBJECTIVES

Using the case of Brazil, we aim to estimate the prevalence of SI during pregnancy and its association with antenatal depression (AD) and sociodemographic factors in a LMIC.

METHOD

We used data from the Brazilian National Survey (PNS-2019), a population-based study, with a complex and probabilistic sampling method. Of the 27,136 women of reproductive age (15 to 49 years old) who participated in the PNS, a total of 769 women reported being pregnant at the time of the interview. All PNS participants answered the Patient Health Questionnaire-9 (PHQ-9) and a questionnaire with sociodemographic data. SI was defined as any answer to the PHQ-9 item 9 other than 0 (not at all). Logistic regression models were performed to obtain crude and adjusted odds ratios (aOR) and 95% confidence intervals (95% CI) for the association between explanatory variables and SI during pregnancy.

RESULTS

Among 769 women, 33 (3.9%, 95% CI: 3.0-5.1%) reported SI during pregnancy. In the adjusted analysis, higher odds of SI were associated with being 20 to 34 years old (aOR:0.24, 95% CI: 0.08-0.74) or 35 to 49 years old (aOR:0.15; 95% CI: 0.04-0.50), having 9 to 11 years of education (aOR 0.23, 95% CI: 0.61-0.86), acheiving the highest family income category (aOR:0.08, 95% CI: 0.01-0.58), not living in the South/Southeast regions of Brazil (aOR:5.52, 95% CI: 2.36-12.9), and having probable mild AD (aOR:10.5 95% CI: 2.3-47.9) or moderate AD (aOR:241.3, 95% CI: 58.4-996.7).

CONCLUSIONS

In Brazil, SI affects almost 4% of pregnant women and is associated with sociodemographic vulnerability. Clinically, women with mild symptoms of depression may also experience SI during pregnancy. These findings are important for designing effective perinatal mental health interventions in LMICs.

A Longitudinal Change Patterns of Depression and Its Relationship with Socioeconomic Deprivation among Middle-Aged Adults in South Korea

This study aimed to identify the longitudinal pattern changes of South Koreans’ midlife depression and determine the impact of socioeconomic deprivation on the observed change in patterns. In total, 3975 middle-aged individuals were examined by conducting a latent class growth analysis and multinomial logistic regression analysis on seven years of Korea Welfare Panel data (2012–2018) using STATA 16.0 (StataCorp LLC, College Station, TX, USA). The change patterns of midlife depression were classified into normal depression reduction group, mild depression maintenance group, and serious depression increase group. The impact of the experience of socioeconomic deprivation on the classified change patterns was examined using the normal depression reduction group as the reference group. It was found that the higher an individual’s nutritional, housing, occupational/economic, and healthcare deprivation, the higher their risk of mild depression maintenance or serious depression increase. The serious depression increase group showed higher relative risk ratios in all domains. Comprehensive and integrated social welfare services, such as stable income, housing welfare, and healthcare services, should be provided along with appropriate clinical interventions for depression alleviation that account for the pattern changes in midlife depression.

Why adults with psychiatric conditions request euthanasia: A qualitative interview study of life experiences, motives and preventive factors

OBJECTIVE

As the empirical picture of adults with psychiatric conditions (further referred to as 'patients') requesting euthanasia is still incomplete, this study aims to deepen our understanding of why these patients request euthanasia, how this relates to the option of suicide, and what could have prevented these patients from considering death and requesting euthanasia.

METHODS

A qualitative study using in-depth, face-to-face interviews was conducted with 16 patients who had their euthanasia request under assessment in the period 2016-2020. Thematic coding was used.

FINDINGS

Most patients were in a state of feeling emotionally worn-out as a result of the many accumulated misfortunes and setbacks, leading to the all-pervasive sense that life is no longer worth living. Whereas some patients reported lifelong adversity, others struggled predominantly in later life. Whereas some patients longed for death strongly, others expressed ambivalence towards death ideation, and some even requested euthanasia to hear of their ineligibility for it, to restore hope and to (re)find meaning in life. patients valued euthanasia over suicide as being more dignified and acceptable, both for themselves and for their inner circle. With regard to preventive factors, patients posited the need for improved accessibility and quality of mental healthcare, as well as a profound change in society's perception of, and support for, these patients.

CONCLUSIONS

This study revealed the many complexities of euthanasia in the context of psychiatry, due to the many differences in patients' background characteristics, in their motives for requesting euthanasia, and the multi-layered aspects of mental suffering that go beyond the field of psychiatry.

Home as the first site for suicide prevention: a Hong Kong experience

INTRODUCTION

There has been little research into at-home suicide cases globally, and particularly in Asian regions. This study aimed to investigate the differences in characteristics between suicide cases in Hong Kong that occurred at home and elsewhere; identify at-home suicide hotspots in the community and compare the differences in area-level characteristics between suicide hotspots and other areas.

METHODS

Suicide cases (2013-2017) were identified from Hong Kong Coroner's Court reports. Area-level socioeconomic data were retrieved from the 2016 Hong Kong census. Wilcoxon signed-rank tests, χ² tests and multiple logistic regression models were applied to compare differences in characteristics between people committing suicide at home and elsewhere. Global hotspot tests (Moran's I and Getis-Ord General G) and local analysis (Getis-Ord Gi*) identified at-home suicide community hotspots. The Wilcoxon signed-rank test was used to compare differences in area-level characteristics between at-home suicide hotspots and non-hotspots.

RESULTS

About 60% of suicide cases in Hong Kong occurred at home. Being female, widowed and/or living alone were significant predictors of at-home suicide cases. A U-shaped association between age and at-home suicide was identified, with 32 years of age being the critical turning point. An at-home suicide hotspot was identified in the north-western region of Hong Kong, which had lower median household income, higher income inequality and higher percentages of households with single elderly people, and new arrivals, compared with other areas.

CONCLUSION

Suicide prevention should start at home by restricting access to suicide methods. Community-based suicide prevention interventions with improvement of social services should target vulnerable members in identified suicide hotspots.

Marital status, educational attainment, and suicide risk: a Norwegian register-based population study

Background

The presence and quality of social ties can influence suicide risk. In adulthood, the most common provider of such ties is one’s partner. As such, the link between marital status and suicide is well-documented, with lower suicide risk among married. However, the association between marital status and educational level suggest that marriage is becoming a privilege of the better educated. The relationship between educational attainment and suicide is somewhat ambiguous, although several studies argue that there is higher suicide risk among the less educated. This means that unmarried with low education may concurrently experience several risk factors for suicide. However, in many cases, these associations apply to men only, making it unclear whether they also refer to women. We aim to investigate the association between marital status, educational attainment, and suicide risk, and whether these associations differ across sexes.

Methods

Our data consist of Norwegian residents aged 35–54, between 1975 and 2014. Using personal identification-numbers, we linked information from various registers, and applied event history analysis to estimate suicide risk, and predicted probabilities for comparisons across sexes.

Results

Overall, associations across sexes are quite similar, thus contradicting several previous studies. Married men and women have lower suicide risk than unmarried, and divorced and separated have significant higher odds of suicide than never married, regardless of sex. Low educational attainment inflates the risk for both sexes, but high educational attainment is only associated with lower risk among men. Being a parent is associated with lower suicide risk for both sexes.

Conclusions

Higher suicide risk among the divorced and separated points to suicide risk being associated with ceasing of social ties. This is the case for both sexes, and especially those with low educational attainment, which both healthcare professionals and people in general should be aware of in order to promote suicide prevention.

Segmenting or Summing the Parts? A Scoping Review of Male Suicide Research in Canada

OBJECTIVE

Suicide in Canadian men is high and rising. Research consistently indicates increased suicide risk in male subgroups including sexual minority, Indigenous, middle-aged, and military men. The current scoping review addresses the research question: Among male subgroups featured in Canadian suicide research, what are the key findings to inform suicide prevention efforts?.

METHOD

A scoping review was undertaken in accord with PRISMA-ScR guidelines. Structured searches were conducted in CIHAHL, Medline, PsychInfo, and Web of Science to identify studies reporting suicidality (suicidal ideation, plans and/or attempts) and suicide among men in Canada. Inclusion criteria comprised primary empirical studies featuring Canadian male subgroups published in English from 2009 to 2020 inclusive.

RESULTS

Sixty-eight articles met the inclusion criteria, highlighting significant rates of male suicidality and/or suicide in 3 categories: (1) health inequities (n = 29); (2) age-specific (n = 30); and (3) occupation (n = 9). The health inequities category included sexual minority men, Indigenous, and other marginalized males (i.e., homeless, immigrant men, and men who use opiates). Age-specific men focused on adolescents and youth, and middle-aged and older males. Active military, veterans, and first responders featured in the occupation category. Studies compared at risk male subgroups to females, general male populations, and/or other marginalized groups in emphasizing mental health disparities and increased suicide risk. Some men's suboptimal connections to existing mental health care services were also highlighted.

CONCLUSION

While male subgroups who are vulnerable to suicidality and suicide were consistently described, these insights have not translated to tailored upstream suicide prevention services for Canadian boys and men. There may be some important gains through integrating social and mental health care services for marginalized men, implementing school-based masculinity programs for adolescent males, orientating clinicians to the potential for men's mid-life suicide risks (i.e., separation, bereavement, retirement) and lobbying employers to norm help-seeking among activate military, veterans, and first responder males.

A systematic review of suicidal behaviour in men: A narrative synthesis of risk factors

RATIONALE

Suicides by men outnumber those by women in every country of the world. To date, there has not been a comprehensive systematic review of risk factors for suicidal behaviour in men to better understand the excess deaths by suicide in men.

OBJECTIVE

The present systematic review seeks to determine the nature and extent of the risk factors to predict suicidal behaviour in men over time.

METHODS

A range of databases (CINAHL, PsycINFO, Web of Science Core Collection, Pubmed, Embase, and Psychology and Behavioural Sciences Collection) were searched from inception to January 2020 for eligible articles. The findings were collated through a narrative synthesis of the evidence.

RESULTS

An initial 601 studies were identified. Following the inclusion and exclusion criteria, there were 105 eligible studies (62 prospective and 43 retrospective) identified. Overall, the risk factors with the strongest evidence predicting suicidal behaviour in men were alcohol and/or drug use/dependence; being unmarried, single, divorced, or widowed; and having a diagnosis of depression. In the prospective studies, the most consistent evidence was for sociodemographic factors (19 risk factors), mental health/psychiatric illness (16 risk factors), physical health/illness (13 risk factors), and negative life events/trauma (11 risk factors). There were a small number of psychological factors (6 factors) and characteristics of suicidal behaviour (3 factors) identified. The findings from the retrospective studies provided further evidence for the risk factors identified in the prospective studies.

CONCLUSIONS

This systematic review has highlighted the wide range of risk factors for suicidal behaviour in men, in this review alone 68 different risk factors were identified. Many factors can interact and change in relevance throughout an individual's life. This review has identified extensive gaps in our knowledge as well as suggestions for future research.

Longitudinal exposure assessments of neighbourhood effects in health research: What can be learned from people's residential histories?

Health research into neighbourhood effects has generally examined neighbourhoods cross-sectionally, ignoring the fact that neighbourhood exposures might accumulate over people's lives and affect health outcomes later in life. Using longitudinal Dutch register data with complete 15-year residential address histories, we examined whether health effects of neighbourhood socioeconomic characteristics differ between cumulative and current exposures. We illustrated these differences between exposure assessments using suicide mortality among middle-aged adults. All suicides aged 40-64 years between 2012 and 2016 were matched with 10 random controls in a nested case-control design. We measured neighbourhood exposures longitudinally for circular buffers around residential addresses at the current address and through three accumulative measures, each incorporating the residential address history with increasing detail. Covariate-adjusted conditional logistic regressions were used to assess associations between suicide and neighbourhood social fragmentation, population density and unemployment rate. Our results showed that total and male suicide mortality was significantly lower in highly fragmented neighbourhoods when using accumulative exposures, but not when using the current residential address. However, we observed few differences in coefficients between exposures assessments for neighbourhood urbanicity and unemployment rate. None of the neighbourhood characteristics showed evidence that detailed cumulative exposures were a stronger predictor of suicide compared to more crude measures. Our findings provide little evidence that socioeconomic neighbourhood characteristics measured cumulatively along people's residential histories are stronger predictors of suicide mortality than cross-sectional exposures.

Suicidality among adult survivors of childhood cancer: A report from the St. Jude Lifetime Cohort Study

BACKGROUND

Suicide is a serious public health concern. An increased risk of suicide ideation previously has been reported among survivors of childhood cancer.

METHODS

Suicide mortality was assessed for all potentially eligible survivors (those aged ≥18 years who were ≥5 years after their cancer diagnosis; 7312 survivors). Risk factors for acute suicidal ideation were assessed among clinically evaluated survivors (3096 survivors) and the prevalence of acute ideation was compared with that of community controls (429 individuals). The prevalence of 12-month suicidality was assessed among survivors who could be compared with population data (1255 survivors). Standardized mortality ratios compared rates of suicide mortality among survivors with those of the general population. Risk ratios (RRs) and 95% confidence intervals (95% CIs) derived from generalized linear models identified risk factors associated with acute suicidal ideation. Standardized incidence ratios (SIRs) compared the prevalence of 12-month suicidality among survivors with that of a matched sample from the general population.

RESULTS

Survivors reported a similar 12-month prevalence of ideation compared with the general population (SIR, 0.68; 95% CI, 0.35-1.01) and a lower prevalence of suicidal behaviors (planning: SIR, 0.17 [95% CI, 0.07-0.27]; attempts: SIR, 0.07 [95% CI, 0.00-0.15]) and mortality (standardized mortality ratio, 0.60; 95% CI, 0.34-0.86). Among survivors, depression (RR, 12.30; 95% CI, 7.89-19.11), anxiety (RR, 2.19; 95% CI, 1.40-3.40), and financial stress (RR, 1.47; 95% CI, 1.00-2.15) were found to be associated with a higher prevalence of acute suicidal ideation.

CONCLUSIONS

Survivors of childhood cancer were found to be at a lower risk of suicidal behaviors and mortality, yet endorsed a prevalence of ideation similar to that of the general population. These results are in contrast to previous findings of suicidal ideation among survivors and support the need for further research to inform screening strategies and interventions.

LAY SUMMARY

The purpose of the current study was to compare the risk of suicidal ideation, behaviors, and mortality in adult survivors of childhood cancer with those of the general population. Risk factors associated with suicidal ideation among survivors of childhood cancer also were examined. Survivors of childhood cancer reported a similar risk of ideation compared with the general population, but a lower risk of suicidal behaviors and mortality. Psychological health and financial stressors were found to be risk factors associated with suicidal ideation. Although adult survivors of childhood cancer did not report a greater risk of suicidality compared with the general population, psychosocial care in survivorship remains essential.

Small but protective social capital against suicide ideation in poor communities: A community-based cross-sectional study

Coupled with the lowest level of social connectedness, South Korea has the highest suicide rate among the Organization for Economic Co-operation and Development countries. A possible link between community and suicide is social capital imprinted in social connectedness. This study explores whether social capital is protective against suicide ideation in relation to the poverty level of communities, and whether the associations are specific to certain elements of social capital.A total of 908 participants were included to assess cross-sectional association of social capital at individual level with suicide ideation by comparing between poor (government-leased apartments) and non-poor communities (nongovernment-leased apartments). Logistic regression analyses were performed to examine various social capital dimensions in relation to suicide ideation.Suicide ideation was far higher among those living in the poor communities (poor communities 12%; non poor communities 6.3%) and the level of social capital was lower in the poor communities. Nevertheless, the protective effect of social capital, in particular, the cognitive dimension against suicide ideation was demonstrated only in the poor communities (eg, odds ratio = 0.27, 95% confidence interval: 0.12-0.58 for trust in the poor communities). Low income was significantly associated with suicide ideation only in the poor communities, but depression and resilience were associated with suicide ideation both in the poor and non-poor communities.To increase the reliability of the results, established measures based on relevant literature were utilized, but measures on bridging social capital and social network might have relatively low reliability.As to protection against suicide ideation, the extent of reliance on social capital was higher in poor communities than in non-poor communities, in particular, the cognitive dimension was likely to activate in this regard.

Examining suicide-related presentations to the emergency department

OBJECTIVE

Although the Emergency Department (ED) is a frequent point of contact for individuals with suicide-related behaviour (SRB) or ideation, there is limited literature specifically examining presentations to the ED for SRB. This review examines the international literature published in North America, the United Kingdom and Australia relating to presentations to the ED for SRB, with focus on high-risk groups, screening tools used in the ED, and difficulties in classifying ED presentations of SRB.

METHOD

The database PubMed was searched using relevant terms, and national health care administrative data were reviewed.

RESULTS

Psychiatric history, substance use, and lower socioeconomic status were all found to be associated with higher rates of ED presentations for SRB. Limited research exists around ED presentations of SRB by particular high-risk groups, including lesbian, gay, bisexual, and transgender populations and Indigenous peoples. Individuals who present to EDs for SRB are often chronic users of EDs and have a high rate of repeat self-harm and death by suicide.

CONCLUSION

These findings suggest that EDs could serve as a focal point for suicide treatment interventions. Deepening our understanding of ED presentations for SRB could inform further development and implementation of interventions to reduce death by suicide.

Effect of economic crisis on suicide cases: An ARDL bounds testing approach

BACKGROUND

Suicide events observed in various groups, community or countries, especially in the periods of economic recession. It is thought that suicide cases increase when people's income decreases dramatically and they lose their jobs.

AIM/OBJECTIVE

In this study, it was aimed to investigate whether the 2008 economic crisis had any effect on suicides in the United States.

METHODS

Autoregressive distributed lag method was used. For the purpose of the study, the number of suicide-related deaths was taken as the dependent variable, while unemployment rates and 2008 economic crisis were taken as independent variables.

FINDINGS

The short-term and long-term relationships obtained within the scope of the study indicated that the 2008 economic crisis had a statistically significant effect on suicide cases in the United States.

RESULTS AND CONCLUSION

It can be said that the results of this study are consistent with the information which emphasizes that economic crises increase suicide cases in the literature.

Associations of Suicide Rates With Socioeconomic Status and Social Isolation: Findings From Longitudinal Register and Census Data

Suicide represents a major challenge to public mental health. In order to provide empirical evidence for prevention strategies, we hypothesized current levels of low socioeconomic status (SES) and high social isolation (SI) to be linked to increased suicide rates in N = 390 administrative districts since SES and SI are associated with mental illness. Effects of SES on suicide rates were further expected to be especially pronounced in districts with individuals showing high SI levels as SI reduces the reception of social support and moderates the impact of low SES on poor mental health. We linked German Microcensus data to register data on all 149,033 German suicides between 1997 and 2010 and estimated Prentice and Sheppard's model for aggregate data to test the hypotheses, accounting for spatial effect correlations. The findings reveal increases in district suicide rates by 1.20% (p < 0.035) for 1% increases of district unemployment, suicide rate decreases of -0.39% (p < 0.028) for 1% increases in incomes, increases of 1.65% (p < 0.033) in suicides for 1% increases in one-person-households and increases in suicide rates of 0.54% (p < 0.036) for 1% decreases in single persons' incomes as well as suicide rate increases of 3.52% (p < 0.000) for 1% increases in CASMIN scores of individuals who moved throughout the year preceding suicide. The results represent appropriate starting points for the development of suicide prevention strategies. For the definition of more precise measures, future work should focus on the causal mechanisms resulting in suicidality incorporating individual level data.

Influence of Area-Level Characteristics on the Suicide Rate in Korean Adolescents

OBJECTIVE

We aimed to investigate the influence of area-level factors on adolescent suicide and to determine which variables differ according to age and sex.

METHODS

We selected variables that were available for collection through an online database from 2005 to 2015 in the Korean Statistical Information Service and the Korea Labor Institute. We used administrative districts of Korea in 2017 for geographical classification. We examined the relationships between regional suicide rates and area-level variables in male and female subjects aged 10-14 years and 15-19 years. In addition, we analyzed area-level variables in adolescents aged 15-19 years according to sex.

RESULTS

Our findings indicated that several area-level variables affected adolescent suicide rates, varying according to age and sex. Economic problems were shown to be more associated with suicide in male adolescents than in female adolescents. On the other hand, social fragmentation and health services were shown to be more associated with suicide in females.

CONCLUSION

Suicide in adolescents was attributable to area-level factors such as economic status, social fragmentation, and community health services. By identifying area-level variables affecting adolescent suicide rates, we will be able to contribute to implement mental health policies related to adolescent suicide.

Socioeconomic inequalities in suicide mortality in Barcelona during the economic crisis (2006-2016): a time trend study

OBJECTIVES

This study aimed to analyse trends in socioeconomic inequalities in suicide mortality in Barcelona before and after the start of the economic crisis that started at the end of 2008, including both individual factors and contextual factors of the deceased's neighbourhood of residence.

DESIGN

This is a trend study of three time periods: pre-economic crisis (2006-2008), early crisis (2009-2012) and late crisis (2013-2016).

SETTING

Total Barcelona residents between 2006 and 2016 (≥25 years of age) and death data derived from the Judicial Mortality Registry of Barcelona.

PARTICIPANTS

996 deaths by suicide between 2006 and 2016 were analysed.

PRIMARY AND SECONDARY OUTCOME MEASURES

The outcomes were age-standardised suicide mortality rates and the associations (relative and absolute risk) between suicide mortality and individual and contextual characteristics for the three time periods.

RESULTS

From 2006 to 2008, men with a lower educational level were more likely to commit suicide than better educated men (relative risk (RR)=1.46; 95% CI 1.11 to 1.91). This difference disappeared after the onset of the crisis. We found no differences among women. From 2013 to 2016, suicide risk increased among men living in neighbourhoods with higher unemployment levels (RR=1.57; 95% CI 1.09 to 2.25) and among women living in neighbourhoods with a higher proportion of elderly people living alone (RR=2.13; 95% CI 1.15 to 3.93).

CONCLUSIONS

We observed risks for suicide among men living in neighbourhoods of Barcelona with higher unemployment levels and among women living in neighbourhoods with a higher proportion of elderly people living alone. Inequalities in suicide mortality according to educational level tended to disappear during the crisis among men. Thus, it is important to continue to monitor suicide determinants especially in times of economic crisis.

Suicídio em Portugal: um retrato do país

RESUMO Objetivo Identificar padrões de tendências do suicídio registrado em Portugal, tendo em conta um conjunto de variáveis socioeconômicas e demográficas entre os anos 2007 e 2014, de modo a obter uma visão geral desse flagelo em Portugal. Métodos Recorrendo a dados do Instituto Nacional de Estatística (INE) e do Sistema de Informação dos Certificados de Óbito (SICO), foi analisado o suicídio segundo a categoria do CID-10 (Classificação Internacional de Doenças), examinando-se as incidências por gênero, faixa etária e região. Resultados Os mais acometidos pelo suicídio são homens (54,8%), com idade superior a 75 anos (30,9%), e ele ocorre nas zonas economicamente mais desfavorecidas. A mortalidade por suicídio mais elevada encontra-se na região do Alentejo (12,8%). Conclusão A mortalidade por suicídio continua a crescer em Portugal e varia em função do gênero e idade, sendo mais elevada nas regiões do Centro e Sul. É necessária uma estratégia de acompanhamento e de prevenção no âmbito da ação social e dos cuidados de saúde, com importantes variações regionais, e maior vigilância sobre a comercialização ilegal de armas de fogo e de pesticidas.

Socio-Economic Position and Suicidal Ideation in Men

People in low socio-economic positions are over-represented in suicide statistics and are at heightened risk for non-fatal suicidal thoughts and behaviours. Few studies have tried to tease out the relationship between individual-level and area-level socio-economic position, however. We used data from Ten to Men (the Australian Longitudinal Study on Male Health) to investigate the relationship between individual-level and area-level socio-economic position and suicidal thinking in 12,090 men. We used a measure of unemployment/employment and occupational skill level as our individual-level indicator of socio-economic position. We used the Index of Relative Socio-Economic Disadvantage (a composite multidimensional construct created by the Australian Bureau of Statistics that combines information from a range of area-level variables, including the prevalence of unemployment and employment in low skilled occupations) as our area-level indicator. We assessed suicidal thinking using the Patient Health Questionnaire (PHQ-9). We found that even after controlling for common predictors of suicidal thinking; low individual-level and area-level socio-economic position heightened risk. Individual-level socio-economic position appeared to exert the greater influence of the two; however. There is an onus on policy makers and planners from within and outside the mental health sector to take individual- and area-level socio-economic position into account when they are developing strategic initiatives.

Suicide in Portugal: Spatial determinants in a context of economic crisis

This study compares the existing statistical association between suicide mortality and the characteristics of places of residence (municipalities), before and during the current economic crisis, in Portugal. We found that (1) the traditional culture-based North/South pattern of suicidal behaviour has faded away, while the socioeconomic urban/rural divide has become more pronounced; (2) suicide is associated with higher levels of rurality and material deprivation; and (3) recent shifts in suicidal trends may result from the current period of crisis. Strategies targeting rural areas combined with public policies that address area deprivation may have important implications for tackling suicide.

Understanding the social determinants of health among Indigenous Canadians: priorities for health promotion policies and actions

Background

Indigenous Canadians have a life expectancy 12 years lower than the national average and experience higher rates of preventable chronic diseases compared with non-Indigenous Canadians. Transgenerational trauma from past assimilation policies have affected the health of Indigenous populations.

Objective

The purpose of this paper is to comprehensively examine the social determinants of health (SDH), in order to identify priorities for health promotion policies and actions.

Design

We undertook a series of systematic reviews focusing on four major SDH (i.e. income, education, employment, and housing) among Indigenous peoples in Alberta, following the protocol Preferred Reporting Items for Systematic Reviews and Meta-Analysis-Equity.

Results

We found that the four SDH disproportionately affect the health of Indigenous peoples. Our systematic review highlighted 1) limited information regarding relationships and interactions among income, personal and social circumstances, and health outcomes; 2) limited knowledge of factors contributing to current housing status and its impacts on health outcomes; and 3) the limited number of studies involving the barriers to, and opportunities for, education.

Conclusions

These findings may help to inform efforts to promote health equity and improve health outcomes of Indigenous Canadians. However, there is still a great need for in-depth subgroup studies to understand SDH (e.g. age, Indigenous ethnicity, dwelling area, etc.) and intersectoral collaborations (e.g. community and various government departments) to reduce health disparities faced by Indigenous Canadians.

Acute suicidal ideation in middle-aged adults from Brazil. Results from the baseline data of the Brazilian Longitudinal Study of Adult Health (ELSA-Brasil)

Suicidal ideation represents an important burden worldwide. However, little is known about it in low-/middle-income countries. We investigated this issue in a large cross-sectional of Brazilian civil servants (ELSA-Brasil, the Brazilian Health Longitudinal Study, n=15,105). Logistic univariate and multivariate analyses were performed to evaluate the strength of association (odds ratio, OR) between clinical and sociodemographic variables with acute life-weariness (tiredness of life) and suicidal thoughts. The presence of major depressive disorder (MDD), common mental disorders (CMDs), stressful life-events (SLEs) and poor self-perceived physical health was also collected. MDD and CMDs were strongly associated with suicidal ideation in univariate and multivariate analyses. For life-weariness thoughts, a modest, consistent association was found for female gender, being single, non-White ethnicity and poor education. SLEs and poor self-perceived physical health were also associated with suicidal ideation. Espiritism-Kardecism, but not other religions or Atheism/Agnosticism, was associated with lower rates of life-weariness and suicidal thoughts. To conclude, suicidal ideation does not differ in Brazil compared to developed countries, being primarily associated with psychiatric disorders and, to a lesser but significant extent, to social disadvantage, SLEs, poor self-perceived health and being single.

Suicidal Ideation, Suicidal Plan and Suicidal Attempts Among Those with Major Depressive Disorder

Introduction: The aims of the study were to identify the prevalence and sociodemographic and clinical correlates of suicidal behaviours using data from a cross-sectional survey among those with major depressive disorder (MDD) in Singapore. Materials and Methods: The Singapore Mental Health Study (SMHS) was a cross-sectional epidemiological study that surveyed Singapore residents (Singapore citizens and permanent residents) aged 18 years and above. The assessment of mental disorders was established using version 3.0 of the Composite International Diagnostic Interview (CIDI 3.0). For the purposes of this study, suicidal behaviour was assessed by questions which were asked to respondents who answered positively to the screening questions in the CIDI 3.0 “Depression” module. Results: The prevalence of suicidal ideation, plan and attempt among those with lifetime MDD was 43.6%, 13.7% and 12.3%, respectively. We found that suicidal ideation, plan and attempt were significantly associated with ethnicity, education and income. The rate of those who had sought some professional help was higher among those with suicidal plan (71.7%) and attempt (72.3%) as compared to those with suicidal ideation (48.7%) and those with MDD but no suicidal behaviour (29%). Conclusion: Individuals with MDD and suicidal behaviour do differ from their non-suicidal counterparts as they have a different sociodemographic and clinical profile. There is a need for more research and a better understanding of this population which in turn could lead to the development and implementation of relevant interventions.

Attempted and completed suicide: not what we expected?

BACKGROUND

Suicide attempters and suicide completers are two overlapping but distinct suicide populations. This study aims to present a more accurate characterization by comparing populations of suicide attempters and completers from the same geographical area.

METHODS

Samples and procedure: All cases of attempted suicide treated at the emergency room of the Corporacio Sanitària i Universitària Tauli Parc de Sabadell in 2008 (n=312) were compared with all completed suicides recorded in the same geographical area from 2008 to 2011 (n=86). Hospital and primary care records were reviewed for sociodemographic and clinical variables.

STATISTICAL ANALYSIS

Chi-square, ANOVA, and Mann-Whitney U tests were used to identify characteristics related to suicide completion.

RESULTS

Compared to suicide attempters, suicide completers were more likely to be male (73.3% vs. 37.8%; p<0.001), pensioners (73.7% vs. 23.4%; p<0.001), and people living alone (31.8% vs. 11.4%; p=0.006). Suicide completers more frequently presented somatic problems (71.7 vs. 15.7; p<0.001), Major Depressive Disorder (54.7% vs. 27.9%; p<0.001), and made use of more lethal methods (74.1 vs. 1.9; p<0.001). Suicide completers were more likely to have been followed by a primary care provider (50.0% vs. 16.0%; p<0.001). 92.3% of the suicides committed were completed during the first or second attempt.

LIMITATIONS

Suicide completers were not evaluated using the psychological autopsy method.

CONCLUSIONS

Despite presenting a profile of greater social and clinical severity, suicide completers are less likely to be followed by Mental Health Services than suicide attempters. Current prevention programs should be tailored to the specific profile of suicide completers.

Suicide mortality gap between Francophones and Anglophones of Quebec, Canada

PURPOSE

Few studies evaluate language-group differences in suicide mortality. This study assessed the suicide mortality gap between Francophones and Anglophones of Quebec, Canada according to age, sex, method, region and socioeconomic deprivation.

METHODS

Suicide decedents were extracted from the Quebec death file for 1989-2007 (N = 24,465). Age- and sex-specific suicide mortality rates were calculated for four periods (1989-1993, 1994-1998, 1999-2003, 2004-2007) for Francophones and Anglophones aged ≥10 years. Age-standardized rates of suicide by method, region, and level of social and material deprivation were calculated for each sex. Rate ratios and rate differences were estimated.

RESULTS

Suicide rates for Francophones were two to three times higher than rates for Anglophones, and differences were greatest for adults aged 25-64 years. Francophone males had more than two times the rate of suicide by hanging or firearms than Anglophone males. Francophone females had twice the rate of hanging, poisoning or firearm suicide as Anglophone females, although precision was low. Francophone-Anglophone suicide mortality gaps were higher in urban areas despite lower suicide rates, and varied little across levels of social and material deprivation.

CONCLUSIONS

There was a large suicide mortality gap between Francophones and Anglophones of Quebec; especially, among adults aged 25-64 years.

An area-based material and social deprivation index for public health in Québec and Canada

OBJECTIVES

To overcome the absence of socio-economic information in administrative databases and to monitor social inequalities in health, a material and social deprivation index was developed for Québec and Canada.

METHODS

The index is based on the smallest area unit used in Canadian censuses, with 400 to 700 persons on average. It includes six socio-economic indicators grouped along two dimensions - material and social - produced from principal component analyses. The index exists for 1991, 1996, 2001 and 2006 and in different versions, from local areas to the whole of Canada. Numerous products related to the index are available online free of charge.

RESULTS

The index has been used extensively in the field of health and social services, mainly in the province of Québec but also elsewhere in Canada. It has had four main uses, all related to public health: describing geographic variations of deprivation, illustrating inequalities in population health status and in service use according to deprivation, supporting the development of health reports and policies, and guiding regional resource allocation. These applications are facilitated by a close partnership between the producers and users of the index.

CONCLUSION

The deprivation index is a marker of social inequalities in health. It allows for monitoring of inequalities over time and space, and constitutes a useful tool for public health planning, intervention and service delivery.
