This study reports results of a life course study conducted with Inuit in Nunavik to obtain information on the life adversities and cumulative burden of adversity for three groups: those who died by suicide, those who attempted suicide, and those who experienced suicidal ideation but never attempted. The study involved different levels of collaboration between health authorities, front-line health workers and the research team. Results indicate that substance misuse and relational difficulties are most associated with the burden of adversity for those people who died by suicide, while bullying is most associated with the burden of adversity for those people who have made suicide attempts and those who have never made a suicide attempt. Specifically targeting parent-child relations, substance misuse, and bullying may be an important upstream strategy for reducing future suicidality in Nunavik.

Purpose: Adolescence is a key period of transitions in the psychological, cognitive, neurobiological and relational domains, which is associated to high susceptibility to adverse life experiences. However, the way adolescent development alters life paths toward suicide remains unclear. Thereby, we aimed at testing whether and how adolescence interfered with the adversity trajectories of individuals who died by suicide. Methods: In a sample of 303 individuals who died by suicide, longitudinal Burden of Adversity ratings were derived from extensive psychological autopsies and life trajectory narrative interviews conducted with informants. Piecewise Joint Latent Class Models allowed the identification of patterns of adversity trajectories and tested the introduction of breakpoints in life-paths. Classes inferred from the optimal model were compared in terms of socio-demographics, psychopathology, and rate of different adverse life events. Results: The most accurate model derived 2 trajectory patterns with a breakpoint in early adolescence. In the first class ( n = 39), the burden of adversity increased steadily from birth to death, which occurred at 23 ( SE = 1.29). In the second class ( n = 264), where individuals died at 43 years of age ( SE = 0.96), the burden of adversity followed a similar trajectory during infancy but stabilized between 10 and 14 years and started to increase again at about 25. Childhood family instability, dependent events, exposure to suicide, intra-family sexual victimization and affective disorders at death were more frequent in class 1. Conclusions: A bifurcation in trajectories between early and late suicides occurs during adolescence. The dynamic pattern of adversity during this period is a key issue to understand the developmental heterogeneity in suicide risk., (Copyright © 2020 Notredame, Chawky, Beauchamp, Vaiva and Séguin.)

This article reports results of the life trajectories from 92 Inuit who died by suicide, matched for age and gender with 92 living-controls. A proxy-based procedure and semi-structured interviews with informants were conducted to obtain trajectories of developmental events occurring over the life course for suicide and community-matched controls. Results from this research indicate two different trajectories that differentiate the control-group from the suicide-group throughout the life course. Even though the number of suicide attempts are similar between both groups, the suicide-group had a more important burden of adversity, which seemed to create a cascading effect, leading to suicide.

According to the World Health Organization, depression has become the leading cause of disability in the world, contributing significantly to the burden of health issues especially in the industrialized countries. This is a major public health problem, with potential impact on work climates, productivity at work and the continued existence of the organizations. Some recent studies have examined potential links between professional factors and common mental health disorders, but none have demonstrated a direct causal link., Objective: In the present study, we explored possible links between work-related stressors and common mental health disorders, with the objective of determining priority mental health prevention axes., Method: The study used a life trajectory method. We compared professional stressors and difficulties present in other spheres of life in the last five years between two groups: a group of 29 participants with common mental health disorders during the last five years (depression, anxiety disorders, eating disorders, substance use disorders, pathological gambling), and a group of 29 participants who have not experienced a mental health disorder in the last five years. Data were collected from semi-structured interviews with the participants using a life course analysis method. Each participant was interviewed during two or three meetings of two to three hour duration. Questions regarding difficulties in different spheres of life and mental health were asked. More precisely, data were collected with regards to the presence or absence of mental health disorders in the last five years and the nature of mental health disorders and difficulties. Moreover, we collected data pertaining to the most important positive and negative events in different spheres of life that were present in the last five years, including family life, romantic relationships, social life, academic difficulties, losses and separations, episodes of personal difficulties, financial difficulties as well as protective factors. Regarding professional difficulties present in the last five years, data were collected on different kinds of adversities such as difficulties in finding a job, periods of unemployment, frequent job changes, difficult working conditions, discrimination, difficult working relationships with colleagues and with employers, moral harassment and family-work conflicts., Results: Participants with common mental health disorders are more concerned about having general professional difficulties at work and about having difficult working relationships with employers. However, difficulties related to other spheres of life do not differentiate the two groups., Conclusion: It is possible that the work environment is linked to common mental health disorders. In particular, having general professional stressors at the work place and having difficult relationships with employers can impact the occurrence of common mental health disorders. Inversely, these stressors at work can be the consequence of a common mental health disorder. Complementary studies are of interest. Professional stressors can constitute an essential part in the occurrence of common mental health disorders. Thus, the workplace seems a priority environment for deploying effective mental health prevention strategies. Moreover, this can be a strategy for organizations to improve the work climate and to increase productivity., (Copyright © 2017 L'Encéphale, Paris. Published by Elsevier Masson SAS.

Epidemiological data shows an alarming prevalence of suicide in Aboriginal populations around the world. In Canada, the highest rates are found in Inuit communities. In this article, we present the findings of a secondary analysis conducted with data previously collected as part of a larger study of psychological autopsies conducted in Nunavut, Canada. The objective of this secondary analysis was to identify protective factors in the Inuit population of Nunavut by comparing people who died by suicide, people from the general population who attempted suicide, and people from the general population who never attempted suicide. This case-control study included 90 participants, with 30 participants in each group who were paired by birth date, sex, and community. Content analysis was first conducted on the clinical vignettes from the initial study in order to codify the presence of protective variables. Then, inferential analyses were conducted to highlight differences between each group in regards to protection. Findings demonstrated that (a) people with no suicide attempt have more protective variables throughout their lifespan than people who died by suicide and those with suicide attempts within the environmental, social, and individual dimensions; (b) people with suicide attempts significantly differ from the two other groups in regards to the use of services; and (c) protective factors that stem from the environmental dimension show the greatest difference between the three groups, being significantly more present in the group with no suicide attempt. Considering these findings, interventions could focus on enhancing environmental stability in Inuit communities as a suicide prevention strategy., Competing Interests: The authors declare no conflict of interest. The founding sponsors had no role in the design of the study; in the collection, analyses, or interpretation of data; in the writing of the manuscript, and in the decision to publish the results.
