Suicide in the Construction Industry: A Targeted Meta-analysis

Prevalence and associated risk factors for suicidal ideation, non-suicidal self-injury and suicide attempt among male construction workers in Ireland

BACKGROUND

Suicide among male construction workers are reported to be disproportionally high compared to the working age population. However, there is minimal understanding of the prevalence and associated factors for suicidal ideation, non-suicidal self-injury, and suicide attempt among this occupational group globally.

METHODS

A cross-sectional study was conducted on a large sample of male construction workers in Ireland (n = 1,585). We investigated the prevalence of suicidal ideation, non-suicidal self-injury and suicide attempts and sociodemographic, occupational, and mental health factors associated with these three outcomes. Multivariable Poisson regression was performed to estimate the prevalence rate ratio of suicidal ideation (model 1 primary outcome), while multivariable logistic regression was used to estimate the odds ratio of non-suicidal self-injury (model 2 primary outcome), and suicide attempt (model 3 primary outcome).

RESULTS

The lifetime prevalence rate for suicidal ideation was 22%, 6% for non-suicidal self-injury, and 6% for suicide attempt. In univariate modelling, socio-demographic and occupation-specific factors associated with the three outcomes included younger age (suicidal ideation and non-suicidal self-injury), not being in a relationship (suicide attempt) and working 35-44 h per week (suicidal ideation and suicide attempt). The mental health factors generalized anxiety disorder, depression, and suicide bereavement were significantly associated with increased risk of the three outcomes. In fully adjusted multivariable models, increasing severity of generalized anxiety disorder and depression were associated with an increased prevalence rate ratio of suicidal ideation, and a higher odds ratio of non-suicidal self-injury and suicide attempt.

CONCLUSION

Suicidal ideation, non-suicidal self-injury and suicide attempt are significant issues for male construction workers that require specific attention. Findings highlight a need to support younger male construction workers and those bereaved by suicide. They also highlight the need for the early detection and treatment of generalized anxiety disorder and depression in order to intervene in, and potentially prevent, suicidality among male construction workers.

Suicide Rates and Risks Across U.S. Industries: A 29-Year Population-Based Survey

OBJECTIVE

Suicide rates in the working-age U.S. population have increased by over 40% in the last two decades. Although suicide may be linked with characteristics of workplaces and their industries, few studies have reported industry-level suicide rates. No study has reported suicide rates by industry using nationally representative data. This study estimates suicide risks across industries in the U.S. working population.

METHODS

Industry-level estimates of suicide risks require substantial data; we combined 29 years of U.S. suicide data using the National Health Interview Survey (NHIS)-Mortality Linked data from 1986 through 2014, with mortality follow-up through 2015. We conducted survey-weighted Poisson regression analyses to estimate suicide mortality rates and rate ratios across all populations and stratified by gender. All analyses were adjusted first for age, and then for age, employment status, marital status, race/ethnicity, and rurality/urbanicity (demographic-adjusted). Rate ratios compared results for workers in each industry to those for all industries, accounting for the NHIS survey design.

RESULTS

A total of 1,943 suicide deaths were recorded. Age-adjusted suicide rates per 100,000 were highest in the furniture, lumber, and wood industry group (29.3), the fabricated metal industry (26.3), and mining (25.8). Demographic-adjusted rates were higher among men than women in most industries. Demographic-adjusted rate ratios were significantly elevated in the furniture, lumber, and wood industries (Rate Ratio, RR = 1.60, 95% confidence interval, CI = 1.18-2.18); chemicals and allied products (RR = 1.49, 95%CI = 1.04-2.13); and construction (RR = 1.21, 95% CI = 1.03-1.41).

CONCLUSION

Several industries had significantly high suicide rates. Suicide prevention efforts may be particularly useful for workers in those industries.

Revisiting the work-suicide link: renewed evidence and models of analysis in workplace contexts

Suicide is a priority public health problem for the World Health Organization. It is a multifactorial phenomenon, for which there is no effective strategy for prevention and reduction. The scientific knowledge generated has not paid much attention to the differentiating role of work and employment on the phenomenon of suicide. This article first presents Abrutyn's recent conceptual model of suicide, which has a psychosocial, holistic and integrated approach. Based on this model, it examines the most recent and solid evidence and trends linking working conditions and phenomenon of suicide, identifying the most relevant findings in work stress theories. It concludes by pointing out avenues of development for a more holistic and ecological understanding of suicide.

Effectiveness of the Australian MATES in Construction Suicide Prevention Program: a systematic review

Suicide is a major public health issue globally. The World Health Organization has called for nations to create comprehensive national suicide prevention strategies including multisectoral collaboration, awareness raising, advocacy and capacity building. The workplace provides opportunity and structure for suicide prevention programs. However, many of these programs are poorly documented and evaluated. The MATES in Construction (MATES) program is a multimodal workplace-based suicide prevention program designed for and by the construction industry. This systematic review examined the available evidence for the effectiveness of the MATES program and is reported according to PRISMA guidelines. A literature search resulted in the inclusion of 12 peer-reviewed articles published between January 2010 and February 2023 containing primary data of evaluations of MATES. There was evidence of the effectiveness of the MATES program in improving mental health and suicide prevention literacy, helping intentions and reducing stigma. The results highlighted the importance of worker-to-worker peer approaches with workers consistently stating that supervisors were the least trusted resources for mental health and suicide concerns. Favourable results were found in relation to reduced suicide risk in the construction industry. The evidence base for MATES is limited in terms of causal inference with very few controlled evaluations and no experimental studies having been conducted to date. Improved understanding of how the program motivates volunteers, their experiences and research on the longer-term impacts of the program on the industry is required.

"And you feel like you're suffocating … how the fuck am I going to get out of all this?" Drivers and experiences of suicidal ideation in the Australian construction industry

Introduction

This research was designed to generate understandings of drivers and experiences of suicidal ideation and distress among Australian Construction Industry (ACI) workers, as well as what helped during these experiences.

Methods

Fifteen participants, from a variety of ACI or closely associated roles, with an average age of 45 years (29-66), engaged in individual, semi-structured interviews. Interviews were audio-recorded with consent and analyzed using descriptive thematic analysis.

Results

Eight themes relating to what may drive the presence of suicidal ideation and distress were identified; 1) challenges of working within the ACI, 2) relationship and family issues, 3) social disconnection, 4) personal financial hardship, 5) perceived lack of support, 6) alcohol and drug use, 7) child custody/access and legal issues, and 8) experience of mental health challenges, trauma, or a significant adverse life event. Four themes relating to experience and expression of suicidal ideation and distress were identified: 1) suicidal thoughts, 2) impaired thinking, 3) observable expressions of suicidal distress, and 4) lack of observable expressions of suicidal distress. Six themes relating to what helped during experiences and well as what can be done by the ACI to help mitigate experiences, were identified: 1) presence of colleague and managerial support, 2) MATES in Construction, 3) engagement with non-work activities and social support, 4) personal skills and knowledge relating to suicide and mental health, 5) high level industry integration and engagement with support programs, and 6) work hours and expectations changes.

Discussion

Findings highlight several industry and personal related challenges that may drive experiences, with many potentially mitigatable by ACI changes and focused prevention strategies. Participant suicidal thought descriptions align with previously identified constructs deemed central in suicidal trajectories. While findings highlight several observable expressions of suicidal ideation and distress, challenges associated with identifying and assisting individuals in the ACI who may be struggling were also reported. Several factors that helped ACI workers during their experiences, as well as what the ACI can do to mitigate future experiences, were identified. Recommendations are made based on these findings, encouraging a more supportive work environment, as well as continued development and increased awareness of support and education systems.

Suicidal Ideation in the Australian Construction Industry: Prevalence and the Associations of Psychosocial Job Adversity and Adherence to Traditional Masculine Norms

BACKGROUND

Suicide in the Australian Construction Industry (ACI) is a significant issue, however minimal understanding of suicidal ideation prevalence, as well as the potential role psychosocial job adversity and increased adherence to traditional masculine norms may play in its presence, is apparent.

METHOD

A representative sample of Australian men (n = 11,132) were used to create initial understandings of prevalence of suicidal ideation (past two weeks), psychosocial job adversities and level of adherence to traditional masculine norms for the ACI (n = 1721) in comparison to a general population comprised of the remaining employed males from Other Industries (n = 9411). Additionally, due to their reported increased suicide vulnerability investigation of associations between suicidal ideation, psychosocial job adversities and adherence to traditional masculine norms for the ACI were undertaken.

RESULTS

No difference in suicidal ideation prevalence was reported between the ACI and those employed in Other Industries (p > 0.05), however, increased prevalence of psychosocial job adversities (p ≤ 0.001) and adherence to traditional masculine norms (p ≤ 0.001) for the ACI was seen. Significant multivariate associations between suicidal ideation, psychosocial job adversities (OR = 1.79, 95%CI [1.12-2.85]) and two domains of traditional masculine norms, self-reliance (OR = 1.29, 95%CI [1.09-1.51]) and risk-taking (OR = 1.20, 95%CI [1.01-1.41]), were reported.

CONCLUSION

Results suggest need for increased understanding of later stage suicidal trajectory drivers in the ACI. Findings indicate need for prevention group/industry concentration on mitigation of psychosocial job adversities, as well as a more nuanced and increased discussion of the negative role of self-reliance and risk-taking domains of traditional masculine norms may play in ACI suicidal ideation, as opposed to the construct as a whole.
