Socio-economic differentials in mental disorders and suicide attempts in Australia

Rural Suicide: Demographics, Causes, and Treatment Implications

Suicide rates in rural areas are higher than urban areas and growing, with current treatment developments only exacerbating this discrepancy. Within individual factors, both age and gender relate to and intersect with personal values related to self-reliance and attitudes toward mental health difficulties and treatment to increase suicide risk. The lethality ubiquitous in rural environments and occupations is a leading factor in rural suicide rates, with other factors such as race alternately noted to be a key factor but with more mixed findings. The cultural values of rural communities as typically negative toward mental health disclosure and treatment contribute to the disengagement of rural communities from treatment that may otherwise prevent suicides, exacerbating the physical lack of treatment access many rural communities experience. Working within the primary care system alongside increased telehealth utilization are suggested to reduce rural suicide rates.

The role of sleep quality and anxiety symptoms in the association between childhood trauma and self-harm attempt: A chain-mediated analysis in the UK Biobank

BACKGROUND

Childhood trauma is a risk factor for self-harm/suicidal behavior, but research on the potential association linking sleep quality and anxiety symptoms to childhood trauma and self-harm attempt is limited. The aim of this study was to describe the mediating role of sleep quality and anxiety symptoms between childhood trauma and self-harm attempt, and to provide a scientific basis for the prevention of self-harm behaviors.

METHODS

This study ultimately included 11,063 study participants who participated in the baseline survey of this large prospective cohort study of the UK Biobank. We used structural equation modeling (SEM) to analyze the chain mediating role of sleep quality and anxiety symptoms in childhood trauma and self-harm attempt while controlling for covariates.

RESULTS

A total of 19.58 % of study participants self-reported self-harm attempt. Sleep quality was negatively correlated with childhood trauma, anxiety symptoms, and self-harm attempt (p < 0.01). Childhood trauma, anxiety symptoms, and self-harm attempt were positively correlated (p < 0.01). In addition, after adjusting for confounders, anxiety symptoms were able to partially mediate the association between childhood trauma and self-harm attempt (effect value: 0.042, p < 0.01), and sleep quality and anxiety symptoms can chain mediate the association between childhood trauma and self-harm attempt (effect value:0.002, p < 0.01), with a total mediating effect of 65.67 % of the total effect. Subgroup analyses further showed that the mediating effects of sleep quality and anxiety symptoms on childhood trauma and self-harm attempt differed across age, gender, ethnicity, and smoking and drinking subgroups.

CONCLUSIONS

This study found a complex relationship between childhood trauma, sleep quality, anxiety symptoms, and self-harm attempt, with sleep quality and anxiety symptoms mediating the relationship between childhood trauma and self-harm attempt. Multiple avenues of intervention, such as the provision of professional psychological interventions and timely monitoring, should be used to improve the sleep quality and mental health of individuals with traumatic childhood experiences and to prevent the occurrence of emotionally harmful behaviors such as self-harm/suicide.

Understanding the educational inequalities in suicide attempts and their mediators: a Mendelian randomisation study

Background

Educational inequalities in suicide have become increasingly prominent over the past decade. Elucidating modifiable risk factors that serve as intermediaries in the impact of low educational attainment on suicide has the potential to reduce health disparities.

Aims

To examine the risk factors that mediate the relationship between educational attainment and suicide attempts and quantify their contributions to the mediation effect.

Methods

We conducted a two-sample Mendelian randomisation (MR) analysis to estimate the causal effect of educational attainment on suicide attempts, utilising genome-wide association study summary statistics from the Integrative Psychiatric Research (iPSYCH; 6024 cases and 44 240 controls) and FinnGen (8978 cases and 368 299 controls). We systematically evaluated 42 putative mediators within the causal pathway connecting reduced educational attainment to suicide attempts and employed two-step and multivariable MR to quantify the proportion of the mediated effect.

Results

In the combined analysis of iPSYCH and FinnGen, each standard deviation (SD) decrease in genetically predicted educational attainment (equating to 3.4 years of education) was associated with a 105% higher risk of suicide attempts (odds ratio (OR): 2.05; 95% confidence interval (CI): 1.81 to 2.31). Of the 42 risk factors analysed, the two-step MR identified five factors that mediated the association between educational attainment and suicide attempts. The respective proportions of mediation were 47% (95% CI: 29% to 66%) for smoking behaviour, 36% (95% CI: 0% to 84%) for chronic pain, 49% (95% CI: 36% to 61%) for depression, 35% (95% CI: 12% to 59%) for anxiety and 26% (95% CI: 18% to 34%) for insomnia. Multivariable MR implicated these five mediators collectively, accounting for 68% (95% CI: 40% to 96%) of the total effect.

Conclusions

This study identified smoking, chronic pain and mental disorders as primary intervention targets for attenuating suicide risk attributable to lower educational levels in the European population.

Effect of salidroside on neuroprotection and psychiatric sequelae during the COVID-19 pandemic: A review

The coronavirus disease 2019 (COVID-19) pandemic has affected the mental health of individuals worldwide, and the risk of psychiatric sequelae and consequent mental disorders has increased among the general population, health care workers and patients with COVID-19. Achieving effective and widespread prevention of pandemic-related psychiatric sequelae to protect the mental health of the global population is a serious challenge. Salidroside, as a natural agent, has substantial pharmacological activity and health effects, exerts obvious neuroprotective effects, and may be effective in preventing and treating psychiatric sequelae and mental disorders resulting from stress stemming from the COVID-19 pandemic. Herein, we systematically summarise, analyse and discuss the therapeutic effects of salidroside in the prevention and treatment of psychiatric sequelae as well as its roles in preventing the progression of mental disorders, and fully clarify the potential of salidroside as a widely applicable agent for preventing mental disorders caused by stress; the mechanisms underlying the potential protective effects of salidroside are involved in the regulation of the oxidative stress, neuroinflammation, neural regeneration and cell apoptosis in the brain, the network homeostasis of neurotransmission, HPA axis and cholinergic system, and the improvement of synaptic plasticity. Notably, this review innovatively proposes that salidroside is a potential agent for treating stress-induced health issues during the COVID-19 pandemic and provides scientific evidence and a theoretical basis for the use of natural products to combat the current mental health crisis.

Linking suicide and social determinants of health in South Korea: An investigation of structural determinants

Introduction

Studies have shown that suicide is closely related to various social factors. However, due to the restriction in the data scale, our understanding of these social factors is still limited. We propose a conceptual framework for understanding social determinants of suicide at the national level and investigate the relationships between structural determinants (i.e., gender, employment statuses, and occupation) and suicide outcomes (i.e., types of suicide, places of suicide, suicide methods, and warning signs) in South Korea.

Methods

We linked a national-level suicide registry from the Korea Psychological Autopsy Center with the Social Determinants of Health framework proposed by the World Health Organization's Commission on Social Determinants of Health.

Results

First, male and female suicide victims have clear differences in their typical suicide methods (fire vs. drug overdose), primary warning signs (verbal vs. mood), and places of death (suburb vs. home). Second, employees accounted for the largest proportion of murder-suicides (>30%). The proportion of students was much higher for joint suicides than for individual suicides and murder-suicides. Third, among individuals choosing pesticides as their suicide method, over 50% were primary workers. In terms of drug overdoses, professionals and laborers accounted for the largest percentage; the former also constituted the largest proportion in the method of jumping from heights.

Conclusion

A clear connection exists between the investigated structural factors and various suicide outcomes, with gender, social class, and occupation all impacting suicide.

Suicide along the Australian coast: Exploring the epidemiology and risk factors

Suicide is an increasing global concern with multiple risk factors, yet location-based understanding is limited. In Australia, surf lifesavers (SLS) and lifeguards patrol the coast, performing rescues and assisting injured people, including people who suicide. This study is a descriptive epidemiological analysis of Australian coastal suicide deaths. The results will be used to inform training and support surf lifesaving personnel and suicide prevention organisations. This is a population-based cross-sectional study of suicide deaths at Australian coastal locations (between 1 January 2005 and 31 December 2019). Data were sourced from the National Coronial Information System and SLS Australia's Incident Report Database. Analyses explored decedent, incident, and risk factors by sex and method. Across the study period, there were 666 coastal suicide deaths (71.0% male, 43.4% jumping from high places [X80]). Males were more likely to suicide by other means (hanging, self-poisoning, firearm discharge; n = 145, 83.8%), compared to females who were more likely to suicide by drowning ([X71]; n = 77, 37.7%). In one third (n = 225, 38.3%) toxicology was a contributing factor. The risk of coastal suicides was 10.3 times higher during the seven-days prior to their birthday (p<0.001). Evidence of mental ill health was reported in 61.4% (n = 409) of cases and evidence of suicidal behaviour was reported for 37.4% of decedents (n = 249), more prevalent in females. SLS responded in 10.7% (n = 71) of coastal suicides (most jumps from high places; n = 36, 50.7%). Coastal suicides differ to national trends suggesting that location-based differences should be considered during development of preventative and protective measures, especially at a community level. Accessibility, availability, perceived lethality and symbolic qualities are proposed to influence suicide location decisions. These results will guide support and education strategies for surf lifesaving personnel, contributes to established, ongoing suicide surveillance efforts (including hot-spot identification) and add to the limited literature exploring place-based suicide.

Exploring the Impact of Remoteness and Socio-Economic Status on Child and Adolescent Injury-Related Mortality in Australia

Injuries are a leading cause of harm for children. This study explores the impact of determinants of health on children (0-19 years) injury-related mortality (namely remoteness and socio-economic disadvantage, calculated using the index of relative socio-economic advantage and disadvantage (IRSAD)). Cause of death data from the Australian Bureau of Statistics were sourced for children in Australia between 1 July 2007 to 30 June 2017. Fifteen injury categories (ICD-10-AM external cause codes) were used. Burden and trends by injury mechanism were explored. A total of 5153 children died; with road traffic incidents (3.39 per 100,000 population), intentional self-harm (2.46) and drowning (0.72) being the leading mechanisms. Female fatality rates in very remote areas (8.73) were nine times higher than in major cities (Relative Risk [RR] = 8.73; 95% Confidence Interval [95% CI]: 4.23-18.00). Fatality rates increased with remoteness; very remote areas recording an injury-related fatality rated six times (RR = 5.84; 95% CI: 3.76-9.12) that of major city residents. Accidental poisoning and intentional self-harm fatalities were more likely in high IRSAD areas, while road traffic fatalities were more likely in low and mid socio-economic areas (X2 = 69.1; p < 0.001). People residing in regional and remote areas and from low socio-economic backgrounds already face significant health and lifestyle challenges associated with disadvantage. It is time to invest in injury prevention interventions for these populations, as well as upstream policy strategies to minimize any further preventable loss of life.

The role of neuroticism in self-harm and suicidal ideation: results from two UK population-based cohorts

BACKGROUND

Self-harm is common, debilitating and associated with completed suicide and increased all-cause mortality, but there is uncertainty about its causal risk factors, limiting risk assessment and effective management. Neuroticism is a stable personality trait associated with self-harm and suicidal ideation, and correlated with coping styles, but its value as an independent predictor of these outcomes is disputed.

METHODS

Prior history of hospital-treated self-harm was obtained by record-linkage to administrative health data in Generation Scotland:Scottish Family Health Study (N = 15,798; self-harm cases = 339) and by a self-report variable in UK Biobank (N = 35,227; self-harm cases = 772). Neuroticism in both cohorts was measured using the Eysenck Personality Questionnaire-Short Form. Associations of neuroticism with self-harm were tested using multivariable regression following adjustment for age, sex, cognitive ability, educational attainment, socioeconomic deprivation, and relationship status. A subset of GS:SFHS was followed-up with suicidal ideation elicited by self-report (n = 3342, suicidal ideation cases = 158) and coping styles measured by the Coping Inventory for Stressful Situations. The relationship of neuroticism to suicidal ideation, and the role of coping style, was then investigated using multivariable logistic regression.

RESULTS

Neuroticism was positively associated with hospital-associated self-harm in GS:SFHS (per EPQ-SF unit odds ratio 1.2 95% credible interval 1.1-1.2, p_FDR 0.0003) and UKB (per EPQ-SF unit odds ratio 1.1 95% confidence interval 1.1-1.2, p_FDR 9.8 × 10^-17). Neuroticism, and the neuroticism-correlated coping style, emotion-oriented coping (EoC), were also associated with suicidal ideation in multivariable models.

CONCLUSIONS

Neuroticism is an independent predictor of hospital-treated self-harm risk. Neuroticism and emotion-orientated coping styles are also predictive of suicidal ideation.

Widening socioeconomic inequalities in Australian suicide, despite recent declines in suicide rates

PURPOSE

This study aims to investigate trends in socioeconomic inequalities of suicide from 1979 to 2013 for Australian males and females aged 15-34 years and 35-64 years.

METHODS

Data on suicides and population were obtained from national registries. An area-based measure of socioeconomic status (SES) was used, and categorized into low, middle, and high SES areas. Suicide rates for each SES groups were estimated using a negative binomial regression model, adjusted for confounders. Socioeconomic inequalities in suicide were assessed using absolute and relative risk of low-to-high SES areas. Secular changes in socioeconomic inequalities were assessed using trend tests for relative risk.

RESULTS

For young males, there was an increase in socioeconomic inequality driven by a significant decrease in suicide rates in high SES areas. For older males, inequality in suicide increased by 29%, which was related to a marked increase in suicide rates in low SES areas. Inequalities in both young and older female suicides also increased. These increases occurred when corresponding suicide rates in high SES areas decreased.

CONCLUSIONS

Recent widening socioeconomic inequalities in Australian suicide have been primarily associated with declines in suicide rates in high SES areas. However, an increasing inequality in older male suicide is linked with low SES. Efforts targeting people from poor areas, especially older males, should be considered when developing suicide prevention strategy.

Confluence of suicide and drug overdose epidemics in young Australian males: common causality?

BACKGROUND

Young adult (aged 20-34) males experience higher mortality than females, and in age groups immediately younger and older, and with considerable variation in death rates over time. Trends in mortality and the cause structure of deaths among young adult Australian males over 1979-2011 are investigated, with a focus on suicide and drug overdose.

METHODS

Mortality data by age for the period 1979 to 2011 and Australian population figures were obtained from the Australian Bureau of Statistics (ABS). Cause of death was investigated using relevant International Classification of Diseases (ICD) codes, and mortality by cause was examined graphically over time according to various ICD aggregations. Mortality trends were contextualised in relation to labour market changes occurring in Australia from the 1980s to early 2000s.

RESULTS

Although motor vehicle accident (MVA) mortality declined by half between 1980 and 1998 in males, this did not translate into a reduction in total young male mortality because of simultaneous increases in suicide, and drug-related deaths classified as either poisoning (external cause) or drug dependence (mental disorders). When both suicide and drug-related deaths declined concurrently after 1998, total 20-34 year male mortality declined by almost half (46%) over 1998-2011. Declines in external cause mortality accounted for 63% of the total mortality decline in 20-34 year males over 1998-2011. The close temporal coincidence (statistically significant) of increases and declines in suicide and drug-related deaths over a decade suggests related causality.

CONCLUSIONS

The coincidence of young male suicide and drug overdose mortality epidemics over the study period (excess deaths: 5000) suggest related causality such as exposure to common factors, including the labour market liberalisation and de-regulation of the 1990s, and deserves further investigation.

Exploring Harms Experienced by Children Aged 7 to 11 Using Ambulance Attendance Data: A 6-Year Comparison with Adolescents Aged 12⁻17

Many population data sources do not routinely collect data of children under 12, despite research showing that mental health, self-injurious behaviour, and substance ingestion can have severe consequences in this age group. We used 6 years (January 2012 to December 2017) of ambulance attendance data from the Australian state of Victoria to characterise mental health, self-injurious behaviour, and substance ingestion in children aged 7–11. We compared this group to older children aged 12–17. We found that in comparison to those aged 12–17 (n = 26,778), a smaller number of children aged 7–11 years (n = 1558) were experiencing serious harms, with mental health symptomology the most common harmful outcome. Self-injurious behaviour significantly increased in both age groups throughout the study period. For mental health, self-injurious behaviour and substance ingestion in the 7–11 age group, males were significantly over-represented. These aged 7–11 were more likely to ingest pharmaceuticals, rather than alcohol or illicit substances, and suicidal ideation was the most common self-injurious behaviour in this age group. Our study suggests that data collection needs to occur specifically in the 7–11 age group, and importantly, services and interventions to improve mental health and wellbeing will need to be specifically designed and targeted at this age group.

Socioeconomic risk factors for hospital admittance due to a suicide attempt in Belgium: a population-based study using administrative data

PURPOSE

This population-based study aims to investigate socio-economic factors, depression and psychosis as independent risk factors for a suicide attempt that requires hospitalization, and estimate the incidence of suicide attempts.

METHODS

Individual-level administrative data were analysed that were collected for all members of the Socialist Health Insurance Schemes in Belgium during the period 2011-2013 (N = 3,156,030) in the context of the financing of the health care services provided. Bivariate and multivariate odds ratios were calculated for multiple socio-economic factors, socio-demographic factors and the presence of depression and psychosis.

RESULTS

During the study period, 4063 persons were hospitalized due to a suicide attempt. The incidence of suicide attempts with hospital admittance was 48.0/100,000 persons/year. Being unemployed, incapable of work over a shorter or longer period with substitute income, living on social welfare, having an increased healthcare reimbursement, living alone and using antidepressants or antipsychotics were identified as independent factors that contributed to the risk of hospitalization due to a suicide attempt.

CONCLUSIONS

Persons from low income groups, however defined, those living alone, or persons using antidepressants or antipsychotics are at an increased risk of attempting suicide and needing hospitalization for it. A social policy that focuses on the improvement of these factors or their consequences may be expected to have a favourable effect on the number of suicide attempts. Funding of mental health care should also better match population needs.

Differentiation of direct and indirect socioeconomic effects on suicide attempts in South Korea

Despite the wide recognition of the inverse association between socioeconomic position (SEP) and suicidal behaviors, its underlying process and potential mediators are little known. This study investigated the pathway from SEP to suicide attempts with attention to potential mediators.From the Korean Health and Nutrition Examination Survey 2007-2013, which is a nationwide cross-sectional survey of the health and nutritional status, a total of 34,565 participants (≥30 years) were included in the analysis. To unfold the pathways linking SEP to suicide attempts, the direct and indirect effects of 3 SEP measures (educational attainment, household income, and occupational group) and 3 mediators (physical illness, mental health problems, and problematic drinking) were differentiated using structured equation model (SEM).Most of direct and indirect effects of educational attainment, household income, and occupational group on suicide attempts were significant; Nonemployment status had the largest total (β = 0.291, P < .01) and direct effects (β = 0.212, P < .01), while educational attainment had the largest indirect effect (β = -0.124, P < .01). Educational attainment was mainly mediated by physical illness and problem drinking, whereas household income and occupational group were mainly mediated by anxious or depressed mood and problem drinking. Physical illness played a major role in explaining suicide attempts, compared to mental health problem and problem drinking.Overall, experience of socioeconomic disadvantage increased suicide attempts independently of mental and physical problems. An extension of suicide prevention program is required for comprehensively targeting people with general problems such as physical illness and low SEP, complemented to narrowly targeting high risk group with, such as mental health problem.

Mental disorders and distress: Associations with demographics, remoteness and socioeconomic deprivation of area of residence across Australia

OBJECTIVES

Australian policy-making needs better information on socio-geographical associations with needs for mental health care. We explored two national surveys for information on disparities in rates of mental disorders and psychological distress.

METHODS

Secondary data analysis using the 2011/2012 National Health Survey and 2007 National Survey of Mental Health and Wellbeing. Key data were the Kessler 10 scores in adults in the National Health Survey (n = 12,332) and the National Survey of Mental Health and Wellbeing (n = 6558) and interview-assessed disorder rates in the National Survey of Mental Health and Wellbeing. Estimation of prevalence of distress and disorders for sub-populations defined by geographic and socioeconomic status of area was followed by investigation of area effects adjusting for age and gender.

RESULTS

Overall, approximately one person in 10 reported recent psychological distress at high/very-high level, this finding varying more than twofold depending on socioeconomic status of area with 16.1%, 13.3%, 12.0%, 8.4% and 6.9% affected in the most to least disadvantaged quintiles, respectively, across Australia in 2011/2012. In the most disadvantaged quintile, the percentage (24.4%) with mental disorders was 50% higher than that in the least disadvantaged quintile (16.9%) in 2007, so this trend was less strong than for Kessler10 distress.

CONCLUSION

These results suggest that disparities in mental health status in Australia based on socioeconomic characteristics of area are substantial and persisting. Whether considering 1-year mental disorders or 30-day psychological distress, these occur more commonly in areas with socioeconomic disadvantage. The association is stronger for Kessler10 scores suggesting that Kessler10 scores behaved more like a complex composite indicator of the presence of mental and subthreshold disorders, inadequate treatment and other responses to stressors linked to socioeconomic disadvantage. To reduce the observed disparities, what might be characterised as a 'Whole of Government' approach is needed, addressing elements of socioeconomic disadvantage and the demonstrable and significant inequities in treatment provision.

What factors contribute to the risk of depression in epilepsy?--Tasmanian Epilepsy Register Mood Study (TERMS)

OBJECTIVE

To model the factors associated with depression in a community sample of people with epilepsy. The factors investigated were derived from proposed risk factors for depression from patients with epilepsy, other chronic illness, and the general population.

METHODS

Multivariate analysis using general linear regression models of factors associated with depression in the Tasmanian Epilepsy Register Mood Study (TERMS), a cross-sectional community sample of 440 patients with epilepsy.

RESULTS

A model with acceptable fit was created that explained 66% of the variance of depression. Associated factors included in this model were neuroticism, physical functioning, social support, past history of depression, and stressful life events.

SIGNIFICANCE

In this cross-sectional study designed specifically to investigate depression in epilepsy, we showed that general risk factors for depression in other illness and in the general population are also important in patients with epilepsy, with little support for disease-related risk factors.

Social connections and suicidal behaviour in young Australian adults: Evidence from a case-control study of persons aged 18-34 years in NSW, Australia

Purpose

There is evidence that social isolation is a risk factor for suicide, and that social connections are protective. Only a limited number of studies have attempted to correlate the number of social connections a person has in their life and suicidal behaviour.

Method

Two population-based case–control studies of young adults (18–34 years) were conducted in New South Wales, Australia. Cases included both suicides (n=84) and attempts (n=101). Living controls selected from the general population were matched to cases by age-group and sex. Social connections was the main exposure variable (representing the number of connections a person had in their life). Suicide and attempts as outcomes were modelled separately and in combination using conditional logistic regression modelling. The analysis was adjusted for marital status, socio-economic status, and diagnosis of an affective or anxiety disorder.

Results

Following adjustment for other variables, those who had 3–4 social connections had 74% lower odds of suicide deaths or attempts (OR=0.26, 95% CI 0.08, 0.84, p=0.025), and those with 5–6 connections had 89% lower odds of suicide deaths or attempts (OR=0.11 95% CI 0.03, 0.35, p<0.001), compared to those with 0–2 social connections. With the number of social connection types specified as a continuous variable, the odds ratio was 0.39 per connection (95% CI 0.27, 0.56, p<0.001).

Conclusions

A greater number of social connections was significantly associated with reduced odds of suicide or attempt. This suggests that suicide prevention initiatives that promote increased social connections at an individual, familial, and wider social levels might be effective.

•

Suicide among young people comprise a serious public health burden.

•

There has been limited research into the factors that may protect against suicide.

•

This study examines social connections and suicide death or attempt.

•

Fewer social connections are associated with greater odds of suicide.

•

Increasing social connections could be important for suicide prevention.

Immigration as risk factor for non-suicidal self-injury and suicide attempts in adolescents in Germany

BACKGROUND

Whereas non-suicidal self-injury (NSSI) and suicide attempts (SA) are rather common among adolescents, the description of risk factors has often failed to take migration into perspective. Our study aimed to describe immigration status in adolescents with regards to their lifetime history of NSSI and SA.

METHODS

We carried out a population based study in a school community of ninth-graders (N = 452, mean age 14.85, SD 0.58) in southern Germany. Data were collected via adolescent self report on sociodemographic variables and on NSSI and SA using the Self Harm Behavior Questionnaire.

RESULTS

Adolescents born outside Germany showed an elevated rate of a lifetime history of NSSI and SA. When compared to German adolescents without a (family) history of migration (NSSI 19.16%, SA 3.24%), adolescents who were born in another country had an elevated risk for NSSI (42.86%, OR 3.36) and SA (17.86%, OR 6.78), which was higher than the risk of adolescents who had at least one parent who had emigrated from another country (NSSI 30.08%, OR 2.46 and SA 8.94%, OR 4.45).

CONCLUSION

Our findings should inform intervention services and prevention programs for NSSI and suicidality in youth. Adopting such programs to include culturally sensible modules could improve the outcome in ethnically diverse adolescents.

Non-suicidal self-injury among psychiatric outpatient adolescent offspring of Croatian posttraumatic stress disorder male war veterans: Prevalence and psychosocial correlates

BACKGROUND

The children of male veterans with combat-related posttraumatic stress disorder (PTSD) are at particularly high risk of emotional and behavioral problems. However, no studies have examined non-suicidal self-injury (NSSI) in this population of youth.

AIMS

To determine the prevalence and psychosocial correlates of lifetime NSSI in a sample of psychiatric outpatient adolescent offspring of Croatian PTSD male veterans.

METHOD

Consecutive outpatient adolescent offspring of Croatian male PTSD veterans, aged 12 to 18 years, were assessed on the Deliberate Self Harm Inventory, the Youth Self-Report, the Family Assessment Device, the Parental Bonding Instrument and the Demographics Questionnaire.

RESULTS

Of the whole sample, 52.7% of adolescents reported NSSI at least once during their lifetime. Lifetime NSSI was significantly associated with internalizing symptoms (adjusted odds ratio (OR) = 2.14; 95% confidence interval (CI): 1.04-4.42, p = .040), poor family functioning (adjusted OR = 6.54; 95% CI: 2.02-21.22, p = .002), lower maternal and paternal care (adjusted OR = 0.47; 95% CI: 0.40-0.56, p = .000 and adjusted OR = 0.82; 95% CI: 0.73-0.91, p = .000, respectively) and higher paternal control (adjusted OR = 1.84; 95% CI: 1.59-2.14, p = .000) in multivariate analysis. No association was found between lifetime NSSI and any of the socio-demographic variables.

CONCLUSION

NSSI is a significant clinical problem in outpatient adolescent offspring of PTSD male veterans, which may be influenced by clinical and family factors. Interventions aimed at reducing internalizing symptoms and improving family functioning and parental behaviors are needed in the treatment of adolescent offspring of male PTSD veterans engaging in NSSI.

Environmental correlates of mental health measures for women in Western Australia

A recent study in Western Australia identified area level associations between soil salinisation and hospital admissions for depression. Our study assessed the quantitative relationship between mental health measures at the individual level and location specific environmental measurements on salinity, as well as two other indicators of environmental degradation and change: land surface temperature and normalised difference vegetation index, a proxy for rainfall. Location-specific environmental measurements were linked to individual mental health scores of women in three age cohorts from the Australian Longitudinal Study on Women's Health using a geographic information system. Bayesian geostatistical linear regression models were developed to assess associations between environmental exposures and mental health scores of women. In contrast to previous studies using area level measures, our study found no associations between individual level measurements of mental health scores for women in south-west Western Australia and salinity, LST or NDVI.

The effects of involuntary job loss on suicide and suicide attempts among young adults: evidence from a matched case-control study

OBJECTIVE

To assess the influence of involuntary job loss on suicide and attempted suicide in young adults.

METHOD

A population-based case-control study of young adults (18-34 years) was conducted in New South Wales, Australia. Cases included both suicides (n=84) and attempts (n=101). A structured interview was conducted with next of kin (for suicide cases) and suicide attempters admitted to hospital. Controls selected from the general population were matched to cases by age and sex. Job dismissal or redundancy (involuntary job loss) in the 12 months before suicide or attempt was the main study variable of interest. Suicide and attempts were modelled separately and in combination as outcomes using conditional logistic regression modelling. The analysis was also adjusted for marital status, socio-economic status and diagnosis of an affective or anxiety disorder.

RESULTS

Following adjustment for other variables, involuntary job loss was associated with an odds ratio of 1.82 for suicide and attempted suicide (combined) (95% CI 0.98 to 3.37; p=0.058). Low socio-economic status was associated with an odds ratio of 3.80 for suicide and attempted suicide (95% CI 2.16 to 6.67; p<0.001) compared to high socio-economic status (after adjustment). Diagnosis of a mental disorder was associated with a 7.87 (95% CI 5.16 to 12.01; p<0.001) odds ratio of suicide and attempted suicide compared to no diagnosis (after adjustment). Involuntary job loss was associated with increased odds of suicide and attempts when these were modelled separately, but results did not reach statistical significance.

CONCLUSIONS

Involuntary job loss was associated with increased odds of suicide and attempted suicide. The strength of this relationship was attenuated after adjustment for socio-economic status and mental disorders, which indicates that these may have a stronger influence on suicide than job loss.

Suicide by occupation: systematic review and meta-analysis

BACKGROUND

Previous research has shown that those employed in certain occupations, such as doctors and farmers, have an elevated risk of suicide, yet little research has sought to synthesise these findings across working-age populations.

AIMS

To summarise published research in this area through systematic review and meta-analysis.

METHOD

Random effects meta-analyses were used to calculate a pooled risk of suicide across occupational skill-level groups.

RESULTS

Thirty-four studies were included in the meta-analysis. Elementary professions (e.g. labourers and cleaners) were at elevated risk compared with the working-age population (rate ratio (RR) = 1.84, 95% CI 1.46-2.33), followed by machine operators and deck crew (RR = 1.78, 95% CI 1.22-2.60) and agricultural workers (RR = 1.64, 95% CI 1.19-2.28). Results suggested a stepwise gradient in risk, with the lowest skilled occupations being at greater risk of suicide than the highest skill-level group.

CONCLUSIONS

This is the first comprehensive meta-analytical review of suicide and occupation. There is a need for future studies to investigate explanations for the observed skill-level differences, particularly in people employed in lower skill-level groups.

Suicidal behaviours in South East London: prevalence, risk factors and the role of socio-economic status

BACKGROUND

Low socio-economic status (SES) is an established risk factor of suicidal behaviours, but it is unknown to what extent its association is direct, indirect or confounded, given its strong association to mental health. We aimed to (I) estimate the prevalence of suicidal behaviours; (II) describe relevant risk factors; and (III) investigate direct and indirect effects of SES on suicidal behaviours.

METHODS

We used cross-sectional community survey data of adults from randomly selected South East London households (SELCoH). Suicidal outcome measures replicated the 2007 Adult Psychiatric Morbidity Survey in England (APMS). Lifetime prevalence was described by socio-demographics, SES, mental health indicators, and life events. Structured symptom screens and a drug use questionnaire measured mental health. Structural equation models estimated direct and indirect effects of a latent SES variable on suicidal ideation and suicide attempts, adjusting for covariates.

RESULTS

20.5% (95% CI: 18.4-22.7) reported suicidal ideation and 8.1% (95% CI: 6.8-9.7) reported suicide attempts (higher than APMS estimates: 13.7%, 4.8%, respectively). Unadjusted risk factors included poor mental health, low SES, and non-married/non-cohabitating relationship status. Black African ethnicity was protective, and women reported more suicide attempts. SES was directly associated to suicide attempts, but not suicidal ideation. SES had indirect effects on suicidal outcomes via mental health and life events.

LIMITATIONS

The cross-sectional design and application of measures for different time periods did not allow for causal inferences.

CONCLUSIONS

Suicidal behaviours were more prevalent than in the general UK population. Interventions targeting low SES individuals may prove effective in preventing suicide attempts.

An international comparison of efficiency of inpatient mental health care systems

There is a fundamental gap in the evidence base on quantitative cross-country comparison of mental healthcare systems due to the challenges of comparative analysis in mental health including a paucity of good quality data. We explore whether existing limited data sources can potentially be exploited to examine technical efficiency of inpatient mental healthcare systems in 32 OECD countries in 2010. We use two analytical approaches: Data Envelopment Analysis (DEA) with bootstrapping to produce confidence intervals of efficiency scores and country rankings, and Cluster Analysis to group countries according to two broad efficiency groupings. We incorporate environmental variables using a two-stage truncated regression. We find slightly tighter confidence intervals for the less efficient countries which loosely corresponds with the 'inefficient' cluster grouping in the Cluster Analysis. However there is little stability in country rankings making it difficult with current data to draw any policy inferences. Environmental factors do not appear to significantly impact on efficiency scores. The most pressing pursuit remains the search for better national data in mental healthcare to underpin future analyses. Otherwise the use of any sophisticated analytic techniques will prove futile for establishing robust conclusions regarding international comparisons of the performance of mental healthcare systems.

Socioeconomic disadvantage, mental disorders and risk of 12-month suicide ideation and attempt in the National Comorbidity Survey Replication (NCS-R) in US

PURPOSE

We aim to explore the distinctive interrelationships between family income and mental disorders on suicidality in recent 12 months.

METHODS

A stratified random subsample of adults in a household survey in US, National Comorbidity Survey Replication, was used for analyses. The ratio of family income to poverty threshold (RoFIPT) per capita was the primary predictor of interest to 12-month occurrence of suicide ideation and attempt. Effect modification by mental disorders was further explored.

RESULTS

A total of 4,724 subjects were analyzed. Inverse associations were found with RoFIPT for both suicidal outcomes after confounding control. Furthermore, effect modification was revealed that RoFIPT was more strongly associated with suicide ideation for those with mental disorders (OR 0.87; 95 % CI 0.79, 0.95).

CONCLUSIONS

An inverse gradient of RoFIPT was shown with suicide ideation and attempt. Moreover, having mental disorders was found to be an effect modifier for the relationships between family income and suicidality.

Latent variable model for suicide risk in relation to social capital and socio-economic status

BACKGROUND

There is little evidence on the association between suicide outcomes (ideation, attempts, self-harm) and social capital. This paper investigates such associations using a structural equation model based on health survey data, and allowing for both individual and contextual risk factors.

METHODS

Social capital and other major risk factors for suicide, namely socioeconomic status and social isolation, are modelled as latent variables that are proxied (or measured) by observed indicators or question responses for survey subjects. These latent scales predict suicide risk in the structural component of the model. Also relevant to explaining suicide risk are contextual variables, such as area deprivation and region of residence, as well as the subject's demographic status. The analysis is based on the 2007 Adult Psychiatric Morbidity Survey and includes 7,403 English subjects. A Bayesian modelling strategy is used.

RESULTS

Models with and without social capital as a predictor of suicide risk are applied. A benefit to statistical fit is demonstrated when social capital is added as a predictor. Social capital varies significantly by geographic context variables (neighbourhood deprivation, region), and this impacts on the direct effects of these contextual variables on suicide risk. In particular, area deprivation is not confirmed as a distinct significant influence. The model develops a suicidality risk score incorporating social capital, and the success of this risk score in predicting actual suicide events is demonstrated.

CONCLUSIONS

Social capital as reflected in neighbourhood perceptions is a significant factor affecting risks of different types of self-harm and may mediate the effects of other contextual variables such as area deprivation.

Effectiveness of Australian youth suicide prevention initiatives

BACKGROUND

After an epidemic rise in Australian young male suicide rates over the 1970s to 1990s, the period following the implementation of the original National Youth Suicide Prevention Strategy (NYSPS) in 1995 saw substantial declines in suicide in young men.

AIMS

To investigate whether areas with locally targeted suicide prevention activity implemented after 1995 experienced lower rates of young adult suicide, compared with areas without such activity.

METHOD

Localities with or without identified suicide prevention activity were compared during the period of the NYSPS implementation (1995-1998) and a period subsequent to implementation (1999-2002) to establish whether annual average suicide rates were lower and declined more quickly in areas with suicide prevention activity over the period 1995-2002.

RESULTS

Male suicide rates were lower in areas with targeted suicide prevention activity (and higher levels of funding) compared with areas receiving no activity both during (RR = 0.89, 95% CI 0.80-0.99, P = 0.030) and after (RR = 0.86, 95% CI 0.77-0.96, P = 0.009) implementation, with rates declining faster in areas with targeted activity than in those without (13% v. 10% decline). However, these differences were reduced and were no longer statistically significant following adjustment for sociodemographic variables. There was no difference in female suicide rates between areas with or without targeted suicide prevention activity.

CONCLUSIONS

There was little discernible impact on suicide rates in areas receiving locally targeted suicide prevention activities in the period following the NYSPS.

Changes in rates, methods and characteristics of suicide attempters over a 15-year period: comparison between Stockholm, Sweden, and Würzburg, Germany

PURPOSE

To investigate age and sex-specific changes in rates, methods used and characteristics of suicide attempters receiving medical care, over a 15-year period in two European WHO catchment areas (Stockholm, Sweden; and Würzburg, Germany).

METHODS

The data for this study were obtained from the WHO/EURO Multicentre Study on Suicidal Behaviour for the period 1989-2003. Sex-specific, person-based suicide attempt rates were calculated for each year separately for the age groups 15-24 and 25 or above. The Chi-square test for trend was applied to estimate changes in proportions of socio-demographic and socio-economic variables.

RESULTS

Significantly, increasing trends in suicide attempt rates occurred in young females, and in males and females aged 25 or above in Würzburg. On the contrary, men 25 years and above showed a significant decrease in suicide attempt rates in Stockholm. Young females in Würzburg tended to use less violent methods for their attempts whereas in Stockholm young females were increasingly inclined to attempt suicide using violent methods. In Stockholm, young female suicide attempters tended to be more often economically inactive, particularly due to an increasing proportion of students. Young females in Würzburg were often less well educated, as were their young male counterparts. This contrasted with trends in the education of men and women of 25 or above in Stockholm.

CONCLUSIONS

The results of this study suggest temporal changes in trends, methods used and in the social profile of suicide attempters.

Prevalence and correlates of lifetime deliberate self-harm and suicidal ideation in naturalistic outpatients: the Leiden Routine Outcome Monitoring study

BACKGROUND

Deliberate self-harm and suicidal ideation (DSHI) are common phenomena in general and mental health populations. Identifying factors associated with DSHI may contribute to the early identification, prevention and treatment of DSHI. Aims of the study are to determine the prevalence and correlates of lifetime DSHI in a naturalistic sample of psychiatric outpatients with mood, anxiety or somatoform (MAS) disorders.

METHODS

Of 3798 consecutive patients from January 2004 to December 2006, 2844 (74.9%) patients were analyzed (mean age=37.5, SD=12.0; age range: 18-65; 62.7% women). Lifetime DSHI was assessed with routine outcome monitoring (ROM), including demographic parameters, DSM-IV diagnosis, depressive symptoms, symptoms of anxiety, general psychopathology and personality traits.

RESULTS

Of the 2844 subjects, 55% reported lifetime DSHI. In multivariable logistic regression analysis, the most important factors associated with lifetime DSHI were being unmarried, low education, high number of psychiatric diagnoses, lower anxiety scores, higher depression scores and the personality trait of emotional dysregulation.

LIMITATIONS

Deliberate self-harm may have been under-reported in self-report questionnaires; The assessment of personality traits may have been influenced by state psychopathology; traumatic events were not assessed.

CONCLUSIONS

The findings suggest that DSHI is common among psychiatric outpatients with MAS disorders and that current symptoms and underlying personality vulnerabilities were independently involved in DSHI. Whether symptoms of somatic anxiety are protective should be confirmed in subsequent studies. These findings may help clinicians in identifying patients at risk for deliberate self-harm and suicide.

Mental disorders and socioeconomic status: impact on population risk of attempted suicide in australia

The population attributable risk (PAR) of mental disorders compared to indicators of socioeconomic status (SES) for attempted suicide was estimated for Australia. For mental disorders, the highest PAR% for attempted suicide was for anxiety disorders (males 28%; females 36%). For SES, the highest PAR% for attempted suicide in males was for occupation (males 31%; females 16%) and education level (males 19%; females 8%), following adjustment for age and mental disorders. The study results suggest that one third of suicide attempts in both males and females are attributable to anxiety disorders, the same proportion attributable to low educational or occupational status.

Sociodemographic correlates of antidepressant utilisation in Australia

OBJECTIVE

To investigate sociodemographic variation in antidepressant utilisation.

DESIGN AND SETTING

Cross-sectional analysis of antidepressant prescription under the Pharmaceutical Benefits Scheme in Australia, 2003-2005.

MAIN OUTCOME MEASURES

Antidepressant utilisation (defined daily dose/1000/day) by sex, age, socioeconomic status (SES) and geographical area.

RESULTS

Total antidepressant utilisation increased with age. Among those aged > or = 15 years, female utilisation was about double that of males. About half of antidepressant utilisation was accounted for by sertraline, venlafaxine, citalopram, and paroxetine. SES differentials in antidepressant utilisation changed across age groups for males and females: among those aged < or = 19 years, total antidepressant utilisation was significantly less in lower SES groups (P < 0.001); there was no relationship to SES among 20-29-year-olds; and among those aged > or = 30 years, antidepressant utilisation was significantly higher in lower SES groups (P < 0.001). SES differences were attenuated after adjusting for urban or rural residence, but remained statistically significant. Antidepressant utilisation rates were highest in regional centres.

CONCLUSION

Antidepressant utilisation in Australia partially reflects sociodemographic differences in the prevalence of affective disorder. Discrepancies between treatment provision and treatment need suggest that not all social strata in Australia have equal access to these treatments.

A relationship between environmental degradation and mental health in rural Western Australia

Australia is currently experiencing a process of escalating ecosystem degradation. This landscape degradation is associated with many outcomes that may directly or indirectly impact on human health. This study used a Bayesian spatial method to examine the effects of environmental degradation (measured as dryland salinity) on the mental health of the resident rural population. An association was detected between dryland salinity and depression, indicating that environmental processes may be driving the degree of psychological ill-health in these populations.

Attitudes towards those bereaved by a suicide: a population-based, cross-sectional study in rural Japan

BACKGROUND

Family or friends bereaved by suicide are at risk of experiencing complications because of attitudes regarding suicide. It is important that individuals close to those grieving after a death by suicide demonstrate adequate knowledge and compassionate attitudes. To this end, we examined the factors that contribute to attitudes toward persons bereaved by the suicide of a family member or friend, and perceptions of suicide prevention and the promotion of mental health.

METHODS

A total of 5154 residents of a rural town in northern Japan aged 30-69 years completed a cross-sectional questionnaire. The questionnaire gathered data about demographic variables, depressive symptoms, and issues related to suicide including personal experience of an acquaintance's suicide, attitudes towards those bereaved by suicide, and perceptions regarding suicide prevention. Factors related to these attitudes and perceptions were analysed using logistic regression models.

RESULTS

Overall, 67.5% of respondents demonstrated appropriate attitudes towards those bereaved by suicide; 30.4% of responses were undetermined, and 2.1% were inappropriate. Undetermined attitudes were associated with male gender (adjusted OR 1.42, 95%CI = 1.26-1.61), younger age (2.64, 2.12-3.29), lower education level (1.32, 1.07-1.62), greater severity of depression (3.81, 2.80-5.20), and lack of personal experience of an acquaintance's suicide (1.39, 1.22-1.57). Inappropriate attitudes were associated with male gender (adjusted OR 1.98, 95%CI = 1.33-2.94), lower education level (2.55 1.34-4.83), and greater severity of depression (6.93, 3.52-13.67). Overall, 16.0% demonstrated passive thoughts regarding suicide prevention and the promotion of mental health in the community, and were associated with male gender (1.22, 1.04-1.42), younger age (2.72, 2.03-3.65), lower education level (1.32, 1.02-1.71), and greater severity of depression (4.94, 3.58-6.82).

CONCLUSION

Factors that contributed to undetermined attitudes included male gender, younger age, lower education level, greater severity of depression, and lack of personal experience of an acquaintance's suicide. Passive thoughts regarding suicide prevention and the promotion of mental health were associated with male gender, younger age, lower education level, and greater severity of depression.

Self-poisoning in rural Sri Lanka: small-area variations in incidence

Background

Self-poisoning is one of the most common methods of suicide worldwide. The intentional ingestion of pesticides is the main contributor to such deaths and in many parts of rural Asia pesticide self-poisoning is a major public health problem. To inform the development of preventive measures in these settings, this study investigates small-area variation in self-poisoning incidence and its association with area-based socioeconomic and agricultural factors.

Methods

Ecological analysis of intentional self-poisoning in a rural area (population 267,613) of Sri Lanka in 2002. The geographic distribution of cases was mapped to place of residence. Using administrative division (GN), median population size 1416, as unit of analysis, associations with socioeconomic and agricultural indicators were explored using negative binomial regression models.

Results

The overall incidence of intentional self-poisoning in the study area was 315 per 100,000 (range: 0 – 2168 per 100,000 across GNs). Socioeconomic disadvantage, as indexed by poor housing quality (p = 0.003) and low levels of education (p < 0.001) but not unemployment (p = 0.147), was associated with a low self-poisoning incidence. Areas where a high proportion of the population worked in agriculture had low overall levels of self-poisoning (p = 0.002), but a greater proportion of episodes in these areas involved pesticides (p = 0.01). An association with extent of cultivated land was found only for non-pesticide poisoning (p = 0.01).

Conclusion

Considerable small-area variation in incidence rates of intentional self-poisoning was found. The noteworthy concentration of cases in certain areas and the inverse association with socioeconomic deprivation merit attention and should be investigated using individual-level exposure data.

Modifiable risk factors for attempted suicide in Australian clinical and community samples

Modifiable risk factors for suicide attempt require identification in clinical and community samples. The aim of this study was to determine if similar social and psychiatric factors are associated with suicide attempts in community and clinical settings and whether the magnitude of effect is greater in clinical populations. Two case-control studies were used: nationwide community-based lifetime attempted suicide (ComAS) cases compared to nationwide community controls; and clinical deliberate self-poisoning (ClinDSP) cases that had hospital treatment compared to normative controls of similar demographic composition. The pattern of risk factors in ComAS and ClinDSP cases was similar, the magnitude of risk usually greater in clinical cases. Greatest attributable fractions were: ComAS current unemployment (39.8% male, 15.5% female) and anxiety disorders (14.0% males, 22.6% females); and ClinDSP current unemployment (69.6% male, 55.5% female) and affective disorders (45.4% male, 39.1% female). Practical intervention targets were unemployment, anxiety and substance use disorders, affective disorders (clinical only), and personality disorder (females only).

Perinatal circumstances and risk of offspring suicide. Birth cohort study

BACKGROUND

A higher risk of suicide has been associated with low birth weight in one study, but not yet replicated. Higher birth order has been associated with self-harm, but not with suicide.

AIMS

To examine the relationship between perinatal circumstances and subsequent young adult suicide in Scotland.

METHOD

Using linked data from the Scottish Morbidity Record and Scottish death records, a birth cohort of 1061830 people was followed-up for a mean of 25.1 years. Data were analysed using Cox regression.

RESULTS

Higher maternal parity, younger maternal age (<25 years), non-professional parental occupations and low birth weight (<2500 g) were independently associated with higher suicide risk of offspring as young adults. There was no independent association with gestational age.

CONCLUSIONS

Our findings provide support for the influence of maternal circumstance and foetal experience on subsequent mental health.

Divergent trends in suicide by socio-economic status in Australia

OBJECTIVES

This study investigated secular trends in socio-economic status (SES) differentials in Australian suicide (1979-2003), which includes overall declines in male suicide from 1998.

METHOD

Suicide rates were stratified by approximate equal-population quintiles of area-based SES for the period 1979-2003 and examined across five quinquennia, centred on each Australian Census from 1981 to 2001, to determine if (1) SES differentials in suicide have persisted over time, and (2) if SES differentials have widened or narrowed. Suicide rates (per 100,000) were adjusted for confounding by sex, age, country-of-birth, and urban-rural residence using Poisson regression models, and secular changes in SES differentials were assessed using trend tests on suicide rate ratios (low to high SES quintiles).

RESULTS

Socio-economic status (SES) differentials persisted across the study period for both males and females after adjusting for the effects of age, migrant status, and urban-rural residence, with the largest differences between low and high SES groups evident in males, and especially young males (20-34 years). For males, suicide rates increased significantly in all SES groups until 1998, before diverging significantly in the most recent 5-year period, particularly in younger males (P<0.0001). In young males, suicide rates in the most recent period increased in the low SES group from 44.8 in 1994-1998 to 48.6 in 1999-2003 (an 8% increase). In contrast, suicide rates in the middle SES group decreased from a peak of 37.3 to 33.5 (a 10% decrease), and in the high SES group from a peak of 33.0 to 27.9 (a 15% decrease). A similar statistically significant divergence of a lesser magnitude was also evident in all age males and younger females (20-34 years).

CONCLUSION

This study shows that SES differentials in suicide persisted in Australia for most of the period 1979-2004. The decline in suicide in young males in the most recent quinquennium was limited to middle and high SES groups, while the low SES group displayed a continued increase. The continued increase in suicide in low SES males has implications for social and economic intervention and suicide control programs.

Hopelessness, demoralization and suicidal behaviour: the backdrop to welfare reform in Australia

OBJECTIVES

To estimate rates of suicidal ideation and attempts, and psychological characteristics of demoralization among Australian income support recipients. To provide information for policy-makers to inform the current welfare reform discussion.

METHOD

Data from the 1997 National Survey of Mental Health and Wellbeing were analysed using sequential logistic regression models, comparing working age people dependent on government income support payments with those having other main sources of income.

RESULTS

Three groups of income support recipients, unemployed, lone mothers and disability payment recipients, reported significantly higher levels on all psychological measures related to demoralization (hopelessness, worthlessness and dissatisfaction with life) than non-recipients. A similar pattern was demonstrated for measures of suicidal ideation and reported suicide attempts, with increased odds of between 3 and 9 for these high-risk groups of welfare recipients. The elevated rates of suicidal ideation, attempts and demoralization among income support recipients were in part explained by sociodemographic characteristics (socioeconomic status, age, educational qualification, experience of serious violence, loneliness, experience of psychiatric disorders), though the unemployed and disability payment recipients remained elevated on the psychological measures.

CONCLUSIONS

Demoralization, poor mental health and suicidal behaviour are common among income support recipients targeted by recently announced welfare reforms. This needs to be considered in the design and implementation of Australian Government policies. Psychiatric epidemiology has a key role in policy development and evaluation.

Rural suicide--people or place effects?

OBJECTIVE

To examine factors that may contribute to elevated rates of suicide among rural communities in Australia.

METHOD

A wide-ranging literature search reviewed possible factors that may contribute to the geographical variation in suicide. Literature was organized to enable examination of compositional and contextual explanations, as well as collective social functioning and social practices.

RESULTS

A variety of factors may contribute to elevated rates of suicide in rural compared with urban areas. Collective and contextual (place) factors seem to be of particular importance as possible contributors to the elevated rate of suicide among rural males. These include rural socioeconomic decline; facilitators and barriers to service utilization such as service availability and accessibility, rural culture, community attitudes to mental illness and help seeking; and exposure to firearms.

CONCLUSIONS

Compositional, contextual and collective factors are hypothesized to influence the elevated rate of suicide in rural compared with urban areas. These factors need to be tested in empirical studies that consider both individual and community-based risk factors, and are designed to enable exploration of likely within-rural differences.

State of animus among Brazilians: influence of socioeconomic context?

Preliminary results of the World Health Survey, conducted in Brazil in 2003, indicate a high frequency of self-perceived problems related to state of animus. The main objective of the present study is to investigate the hypothesis that material deprivation and job insecurity are important determinants of self-reported mental problems, such as feelings of depression and anxiety. Analysis of factors associated with self-perceived problems related to state of animus was performed with multivariate logistic regression models. Among females, key factors associated with feelings of depression and anxiety were level of education and unemployment after controlling for age, presence of long duration disease or disability and of body injury limiting everyday activities. Among males, feelings of depression were most strongly associated with unemployment, followed by poverty (as measured by a household asset indicator), with being married (or cohabiting) showed a protector effect. With regard to severe feelings of anxiety, only unemployment contributed significantly. These findings highlight the influence of social and economic contexts, beyond strictly individual characteristics, on the health of Brazilians.

Self-harm

The term self-harm is commonly used to describe a wide range of behaviours and intentions including attempted hanging, impulsive self-poisoning, and superficial cutting in response to intolerable tension. As with suicide, rates of self-harm vary greatly between countries. 5-9% of adolescents in western countries report having self-harmed within the previous year. Risk factors include socioeconomic disadvantage, and psychiatric illness--particularly depression, substance abuse, and anxiety disorders. Cultural aspects of some societies may protect against suicide and self-harm and explain some of the international variation in rates of these events. Risk of repetition of self-harm and of later suicide is high. More than 5% of people who have been seen at a hospital after self-harm will have committed suicide within 9 years. Assessment after self-harm includes careful consideration of the patient's intent and beliefs about the lethality of the method used. Strong suicidal intent, high lethality, precautions against being discovered, and psychiatric illness are indicators of high suicide risk. Management after self-harm includes forming a trusting relationship with the patient, jointly identifying problems, ensuring support is available in a crisis, and treating psychiatric illness vigorously. Family and friends may also provide support. Large-scale studies of treatments for specific subgroups of people who self-harm might help to identify more effective treatments than are currently available. Although risk factors for self-harm are well established, aspects that protect people from engaging in self-harm need to be further explored.

Mental health and socio-economic variations in Australian suicide

This paper investigates the relationship between suicide rates and prevalence of mental disorder and suicide attempts, across socio-economic status (SES) groups based on area of residence. Australian suicide data (1996-1998) were analysed in conjunction with area-based prevalences of mental disorder derived from the National Survey of Mental Health and Well-Being (1997). Poisson regression models of suicide risk included age, quintile of area-based SES, urban-rural residence, and country of birth (COB), with males and females analysed separately. Analysis focussed on the association between suicide and prevalences of (ICD-10) affective disorders, anxiety disorders, substance use disorders and suicide attempts by SES group. Prevalences of other psychiatric symptomatology, substance use problems, health service utilisation, stressful life-events and personality were also investigated. Significant increasing gradients were evident from high to low SES groups for prevalences of affective disorders, anxiety disorders (females only), and substance use disorders (males only); sub-threshold drug and alcohol problems and depression; and suicide attempts and suicide (males only). Prevalences of mental disorder, other sub-threshold mental health items and suicide attempts were significantly associated with suicide, but in most cases associations were reduced in magnitude and became statistically non-significant after adjustment for COB, urban-rural residence, and SES. For male suicide the relative risk (RR) in the lowest SES group compared to the highest was 1.40 (95% CI 1.29-1.52, p<0.001) for all ages, and 1.46 (95% CI 1.27-1.67, p<0.001) for male youth (20-34 years). This relationship was not substantially modified in males when regression models included prevalences of affective disorders, and other selected mental health variables and demographic factors. From a population perspective, SES remained significantly associated with suicide after controlling for the prevalence of mental disorders and other psychiatric symptomatology. Mental conditions and previous suicidal behaviour may play an intermediary role between SES and suicide, but this study suggests that an independent relationship between suicide and SES also exists.

Social and psychiatric influences on urban-rural differentials in Australian suicide

The purpose of this study was to investigate urban-rural differentials in Australian suicide rates, and to examine influences that previously have remained largely speculative. Suicide rates for males (all ages and young adults) were significantly higher in rural areas compared to urban areas. Urban-rural suicide rate differences in males were rendered nonsignificant after adjustment for migrant and area socioeconomic status. Adjusting for mental disorder prevalence, in addition to migrant status, reduced the excess suicide risk in rural areas; the excess was reduced further with addition of mental health service utilization. The implications of this study are that socioeconomic circumstances in rural populations contribute to higher male suicide rates compared to urban areas, but these conditions may be partly mediated by mental disorder prevalence and mental health service utilization.
