There is conflicting evidence on the suicide rates of different public safety personnel (PSP). There have been few studies that compare suicides in PSP with the general population and none that have used a detailed comparison of coroner records. Background: The current study estimates suicide rates among different PSP and compares PSP suicides with the general population. Aims: The current study estimates suicide rates among different PSP and compares PSP suicides with the general population. Method: We identified 36 PSP suicides and 72 general population controls. Police had a higher suicide rate than other PSP groups. PSP were more likely to die by firearm, be separated/divorced or married, die in a motor vehicle, have problems at work, and have a PTSD diagnosis. PSP were less likely to die by jumping. Results: We identified 36 PSP suicides and 72 general population controls. Police had a higher suicide rate than other PSP groups. PSP were more likely to die by firearm, be separated/divorced or married, die in a motor vehicle, have problems at work, and have a PTSD diagnosis. PSP were less likely to die by jumping. Limitations: The study may have not identified all PSP suicides. Apart from the cause of death, data in coroner records are not systematically collected, so information may be incomplete. Conclusion: PSP suicides appear different than the general population. Death records need to have an occupation identifier to enable monitoring of trends in occupational groups, such as PSP.

Emerging evidence, based on the synthesis of reports from past infectious disease-related public health emergencies, supports an association between previous pandemics and a heightened risk of suicide or suicide-related behaviours and outcomes. Anxiety associated with pandemic media reporting appears to be one critical contributing factor. Social isolation, loneliness, and the disconnect that can result from public health strategies during global pandemics also appear to increase suicide risk in vulnerable individuals. Innovative suicide risk assessment and prevention strategies are needed to recognise and adapt to the negative impacts of pandemics on population mental health., Competing Interests: None declared.

Background: Self-harm is increasing among adolescents, and because of changing behaviours, current data are needed on the consequences of self-harm. We sought to investigate the trends related to hospital presentation, readmission, patient outcome and medical costs in adolescents who presented with self-harm to the emergency department., Methods: We used administrative data on 403 805 adolescents aged 13-17 years presenting to Ontario emergency departments in 2011-2013. Adolescents with self-harm visits were 1:2 propensity matched to controls with visits without self-harm, using demographic, mental health and other clinical variables. Five years after the index presentation, hospital or emergency department admission rates for self-harm, overall mortality, suicides and conservative cost estimates were compared between the 2 groups., Results: Of 5832 adolescents who visited Ontario emergency departments in 2011-2013 after self-harm (1.4% of visits), 5661 were matched to 10 731 adolescents who presented for reasons other than self-harm. Adolescents who presented with self-harm had a shorter time to a repeat emergency department or hospital admission for self-harm (hazard ratio [HR] 4.84, 95% confidence interval [CI] 4.44-5.27), more suicides (HR 7.96, 95% CI 4.00-15.86), and higher overall mortality (HR 3.23, 95% CI 2.12-4.93; p < 0.001). The positive predictive value of self-harm-related emergency department visits for suicide was 0.7%. Adolescents with self-harm visits had mean 5-year estimates of health care costs of $30 388 compared with $19 055 for controls ( p < 0.001)., Interpretation: Adolescents with emergency department visits for self-harm have higher rates of mortality, suicide and recurrent self-harm, as well as higher health care costs, than matched controls. Development of algorithms and interventions that can identify and help adolescents at highest risk of recurrent self-harm is warranted., Competing Interests: Competing interests: William Gardner reports receiving grants from the Canadian Institutes of Health Research and research contracts from the Public Health Agency of Canada and the US Centers for Disease Control.

Background: Understanding suicidality has proven challenging given the complex aetiology in early childhood. Being able to accurately predict groups at increased risk of developing suicidal thoughts may aid in the development of targeted prevention programs that mitigate increased vulnerability. Further, the predictors of suicidal thoughts may be shared with other outcomes in adolescence. Previous research has linked many factors to suicidality, so the objective of this study was to consider how these factors may act together to increase risk of suicidal thoughts and other non-mental health outcomes., Methods: Two longitudinal datasets were used in this analysis: the National Longitudinal Survey of Children and Youth (NLSCY) and the Avon Longitudinal Survey of Parents and Children (ALSPAC). A Classification and Regression Tree model comprised of 75 factors describing early childhood was constructed to identify subgroups of adolescents at high risk of suicidal thoughts in the NLSCY and was validated in ALSPAC. These subgroups were investigated to see if they also had elevated rates of antisocial behaviour, substance misuse, poor physical health, poor mental health, risky health behaviours, and/or poor academic performance., Results: The sensitivity was calculated to be 22·7%, specificity was 89·2%, positive predictive value 17·8%, and negative predictive value 91·8% and had similar accuracy in the validation dataset. The models were better at predicting other adverse outcomes compared to suicidal thoughts., Conclusion: There are groups of risk factors present in early life that can predict higher risk of suicidality in adolescence. Notably, these factors were also predictive of a range of adverse outcomes in adolescence.

Purpose of Review: To provide an update on recent studies on suicide prevention in indigenous populations with a focus on recently colonised indigenous peoples in Canada, the United States, Australia and New Zealand., Recent Findings: There have been several recent reviews on suicide prevention in indigenous populations with high suicide rates. However most of them describe the problem and there is little new that is available on effective interventions. One randomized controlled trial of a package of measures focusing on cultural identity in Maori who had recently self-harmed compared to usual care found little effect on suicidal behavior but it did significantly reduce presentations to hospital for any reason after one year., Summary: The reasons for the limited evidence include a lack of ring fenced funding and a lack of research infrastructure; the problem of high rates of suicide but small numbers; and the difficulty in creating effective collaborations between researchers and communities. Potential solutions include identifying specific research funding; improving capacity in indigenous research; putting effort into accurate identification and recording of ethnicity; and thinking about the problem of suicide in recently colonised populations as a global problem to enable large scale high quality studies to take place.

This perspective article describes the problem of Canadian indigenous suicide from a non-Canadian viewpoint. In particular, the article compares both similarities and differences in suicide prevention between Māori in New Zealand and indigenous peoples in Canada. It emphasises that the problem of indigenous suicide is not being indigenous but coping with losses secondary to colonisation. A useful way to translate this into helpful clinical conversations and actions is to think about loss of belonging. Culture and belonging are key components of identity and as such should be considered in all psychiatric encounters, not just in those who are considered minorities or "other." The article concludes by suggesting how some of the experiences of addressing health inequalities and suicide in Māori may be applied in Canada., Competing Interests: The author(s) declared no potential conflicts of interest with respect to the research, authorship, and/or publication of this article., (© The Author(s) 2016.)

Objective: To systematically review the research on the association between sense of belonging and suicide., Method: We systematically reviewed electronic databases for studies that included assessments of suicidality and belonging., Results: We found 16 studies that met our eligibility criteria. They all found an association between belonging and suicidality but nearly all of the studies were in nonclinical populations, and the association was weak and could be taken into account by confounding factors., Conclusions: Low sense of belonging has a weak association with suicidality. However, current concepts make it hard to distinguish from loneliness or other measures of social support. An alternative view of belongingness, as a sense of connectedness to things other than people and in the past as well as the present, may generate alternative ideas about useful clinical interventions that may be especially relevant to indigenous populations.

Objective: To investigate adult presentations to North Shore Hospital, Auckland, New Zealand, following deliberate self-harm, determine re-presentation and suicide rates and investigate the characteristics of those patients who re-present., Methods: Retrospective review of a cohort of adult patients presenting to North Shore Hospital Emergency Care Centre in Auckland, New Zealand, with deliberate self-harm between 1 January 2001 and 31 August 2002, using data from the National Minimum Data Set and Hospital Discharge Database. The re-presentation rate was calculated as the percentage of patients presenting a second time within 1 year of their index presentation. The suicide rate was calculated as the percentage of patients with a coroner's verdict of suicide within 1 year of their index presentation of deliberate self-harm., Results: There were 1055 presentations by 754 people during the presentation period. Of these 754 people, 136 presented for a second time within a year of the index case (136/754 [18.0%, 95% CI 15.5-21.0]). Eight of the seven hundred and fifty-four people went on to commit suicide within 1 year (8/754 [1.1%, 95% CI 0.5-2.1]). Self-poisoning was the most common method of self-harm. Minor tranquillizers were used more commonly in the group who re-presented., Conclusion: Re-presentation and suicide rates in our study were similar to previously published rates. Further research is needed to identify strategies to reduce re-presentations and excess mortality in all people who deliberately self-harm.

Aim: The aim of this study was to describe the population of people who had committed suicide in Auckland in the nine years, 1989 to 1997., Methods: We extracted data from the police records to the coroner and the autopsy reports on people who had killed themselves in the Auckland coronial region., Results: Suicide is common and disproportionately affects young men, the unemployed and sickness beneficiaries. Few people who kill themselves appear to be in contact with the mental health services., Conclusions: For effective prevention, up to date local information on suicide and deliberate self-harm is needed.

This study is a descriptive survey of financial difficulties in a consecutive series of patients who deliberately poisoned themselves. Over three months 160 such patients presented to the liaison psychiatry service at Leeds General Infirmary. Information was available on 147 of these patients, of whom 54 (37%) had problem debts. Patients in debt were more likely to harm themselves with greater suicidal intent and, after the episode, to report more symptoms of depression and hopelessness. Psychiatrists were more likely to diagnose mental illness in those in debt.
