Work-related suicide: Evolving understandings of etiology & intervention.

Previously published analyses of suicide case investigations suggest that work or working conditions contribute to 10%-13% of suicide deaths. Yet, the way in which work may increase suicide risk is an underdeveloped area of epidemiologic research. In this Commentary, we propose a definition of work-related suicide from an occupational health and safety perspective, and review the case investigation-based and epidemiologic evidence on work-related causes of suicide. We identified six broad categories of potential work-related causes of suicide, which are: (1) workplace chemical, physical, and psychosocial exposures; (2) exposure to trauma on the job; (3) access to means of suicide through work; (4) exposure to high-stigma work environments; (5) exposure to normative environments promoting extreme orientation to work; and (6) adverse experiences arising from work-related injury or illness. We summarise current evidence in a schema of potential work-related causes that can also be applied in workplace risk assessment and suicide case investigations. There are numerous implications of these findings for policy and practice. Various principle- and evidence-based workplace intervention strategies for suicide prevention exist, some of which have been shown to improve suicide-prevention literacy, reduce stigma, enhance helping behaviours, and in some instances maybe even reduce suicide rates. Prevailing practice in workplace suicide prevention, however, overly emphasises individual- and illness-directed interventions, with little attention directed to addressing the working conditions that may increase suicide risk. We conclude that a stronger emphasis on improving working conditions will be required for workplace suicide prevention to reach its full preventive potential.

Employment-related mental health outcomes among Australian migrants: A 19-year longitudinal study.

BACKGROUND: Migrants experience various stressors at different stages of migration based on their country of origin, ethnic backgrounds, migration context and host country. Employment is one important post-settlement factor associated with mental health among migrant groups. The study investigates whether the country of origin modifies the association between employment and mental health for Australian migrants. METHODS: Nineteen waves of data from the Household Income and Labour Dynamics in Australia Survey were used. Using fixed-effects regression, we examined the effects of within-person changes in employment status on mental health outcomes as measured by the Mental Health Inventory (MHI-5), controlling for time-varying confounders and stratified by sex and examined effect modification by country of origin. RESULTS: The relationship between unemployment and mental health was modified by country of origin for men but not women. Unemployed men from Asian (ß = -4.85, p < 0.001), African and Middle Eastern (ß = -3.61, p < 0.05) countries had lower mental health scores compared to employed Australian-born men. For men, there was evidence of effect modification of the association between employment and mental health by country of origin, with the combined effect of being unemployed and being a migrant from an Asian country was almost three points lower than the summed independent risks of these factors (ß = -2.72; p = 0.01). Also, for men, the combined mental health effect of not being in the labour force and coming from a non-English-speaking European country was greater than the summed effects of these factors (ß = -2.33; p < 0.001). CONCLUSION: Tailored employment-support programmes may be beneficial for migrants from ethnic minorities, particularly those from Asian, African and Middle Eastern countries in Australia. Further research is needed to understand why the mental health of migrant men from these countries is particularly vulnerable to unemployment.

Conceptual foundations of a gender equality index.

Gender equality indexes (GEIs) have become a popular tool for the quantification of unequal resource distribution between males and females. Creating such an index implies an understanding of what gender inequality is, though this question has remained the province of theoretical feminism with little explicit treatment in the methodologically focussed literature. This paper presents an empirically minded, theoretical account of gender inequality, which can be used broadly to inform the development of GEIs. The account proceeds in three steps. First, we argue for a broad understanding of the types of resources that structure gender inequality. Drawing on the work of Bourdieu, we highlight the importance of including symbolic capitals (and indeed viewing gender itself as a symbolic capital). By considering gender as a symbolic capital, we are drawn to the ways that normative maleness hides some types of gender inequality. Thus, caregiving norms and leisure time inequality are brought to the foreground. Finally, in recognizing that there is no single unifying female experience, we describe the ways that gender inequality intersect with other forms of disadvantage, motivating the incorporation of (particularly) race into the index. The result is a comprehensive-and theoretically defensible-set of indicators for the measurement of gender inequality.

Suicide in welfare support workers: a retrospective mortality study in Australia 2001-2016.

OBJECTIVES: Employees working in the welfare and healthcare industry have poorer mental health than other occupational groups; however, there has been little examination of suicide among this group. In this study, we examined suicide rates among welfare support workers and compared them to other occupations in Australia. METHODS: We used data from the National Coroners Information System to obtain suicide deaths between the years 2001 and 2016. Using the Australian standard population from 2001 and Census data from 2006, 2011 and 2016, we calculated age-standardised suicide rates and rate ratios to compare suicide rates across different occupational groups. RESULTS: Overall, the age-standardised suicide rate of welfare support workers was 8.6 per 100 000 people. The gender-stratified results show that male welfare support workers have a high suicide rate (23.8 per 100 000 people) which is similar to male social workers and nurses (25.4 per 100 000). After adjusting for age and year of death, both males (rate ratio 1.48, 95% CI 1.23 to 1.78) and female welfare support workers (rate ratio 1.49, 95% CI 1.20 to 1.86) have higher suicide rate ratios compared with the reference group (excluding occupations from the comparison groups). CONCLUSION: The age-standardised suicide rates of male welfare support workers are comparable to occupations which have been identified as high-risk occupations for suicide. Both female and male welfare support workers are at elevated risk of suicide compared with other occupations. Further research is required to understand the drivers of the elevated risk in this group.

Gendered associations between household labour force participation and mental health using 17 waves of Australian cohort data.

PURPOSE: There is some evidence that employed women report more time pressure and work-life penalties than employed men and other women; however little is known about whether this exerts a mental health effect. This analysis examined associations between household labour force arrangements (household-employment configuration) and the mental health of men and women. METHODS: Seventeen waves of data from the Household Income and Labour Dynamics Survey (2001-2017) were used. Mental health was measured using the Mental Health Inventory (MHI-5). A six-category measure of household-employment configuration was derived: dual full-time employed, male-breadwinner, female-breadwinner, shared part-time employment (both part-time), male full-time/female part-time (modified male-breadwinner, MMBW), and female full-time/male part-time. Using fixed-effects regression methods, we examined the within-person effects of household-employment configuration on mental health after controlling for time-varying confounders. RESULTS: For men, being in the female-breadwinner configuration was associated with poorer mental health compared to being in the MMBW configuration (ß-1.98, 95% CI - 3.36, - 0.61). The mental health of women was poorer when in the male-breadwinner configuration, compared to when in the MMBW arrangement (ß-0.89, 95% CI - 1.56, - 0.22). CONCLUSION: These results suggest that the mental health of both men and women is poorer when not in the labour force, either as a man in the female-breadwinner arrangement, or as a woman in the male-breadwinner arrangement. These results are particularly noteworthy for women, because they pertain to a sizeable proportion of the population who are not in paid work, and highlight the need for policy reform to support women's labour force participation.

Sexual and reproductive health service utilisation of adolescents and young people from migrant and refugee backgrounds in high-income settings: a qualitative evidence synthesis (QES).

Young people with migrant or refugee backgrounds from low- and middle-income countries settle in high-income countries and tend to underutilise sexual and reproductive health (SRH) services. This review aimed to explore perceptions and experiences of SRH services and the factors that shape their use among migrant youth. It focuses on qualitative studies that examine SRH service use among young migrants living in high-income countries. Seven peer-review databases and web-based grey literature were searched using pre-determined search criteria. The review includes 16 articles that met the inclusion criteria. The qualitative evidence synthesis (QES) method was used to synthesise findings. Thematic analysis resulted in five main themes and 11 sub-themes. Findings suggest that despite diversity of countries of origin and host countries, there were considerable similarities in their perceptions of and experiences with SRH services. Some young migrants reported experiences of discrimination by service providers. Cost of care was a deterrent to SRH service use in countries without universal healthcare coverage. Lack of information about SRH services, concerns about confidentiality, community stigma around sexually transmitted infections and premarital sex were key barriers to SRH service use. Health systems should integrate flexible service delivery options to address access barriers of SRH service use in young migrants. Engagement with parents and communities can help to destigmatise sexual health problems, including STIs. Host countries need to equip young migrants with the knowledge required to make informed SRH decisions and access relevant SRH services and resources.

Gendered working environments as a determinant of mental health inequalities: a systematic review of 27 studies.

BACKGROUND: 'Gendered working environments' describes the ways in which (1) differential selection into work, (2) variations in employment arrangements and working hours, (3) differences in psychosocial exposures and (4) differential selection out of work may produce varied mental health outcomes for men and women. The aim of this study was to conduct a systematic review to understand gender differences in mental health outcomes in relation to the components of gendered working environments. METHODS: The review followed a Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) search approach and focused on studies published in 2008-2018. The protocol for the review was prospectively registered with PROSPERO (CRD42019124066). FINDINGS: Across the 27 cohort studies included in the review, we found that (1) there was inconclusive evidence on the effect of occupational gender composition on the mental health of men and women, (2) women's mental health was more likely to be affected by long working hours than men's; however, precarious employment was more likely to be negatively associated with men's mental health, (3) exposure to traditional constructs of psychosocial job stressors negatively affected the mental health of both women and men, and (4) unemployment and retirement are associated with poorer mental health in both genders. INTERPRETATION: The findings from this review indicate that gendered working environments may affect the mental health of both men and women, but the association is dependent on the specific exposure examined. There is still much to be understood about gendered working environments, and future research into work and health should be considered with a gender lens.

Male suicide among construction workers in Australia: a qualitative analysis of the major stressors precipitating death.

BACKGROUND: Suicide rates among those employed in male-dominated professions such as construction are elevated compared to other occupational groups. Thus far, past research has been mainly quantitative and has been unable to identify the complex range of risk and protective factors that surround these suicides. METHODS: We used a national coronial database to qualitatively study work and non-work related influences on male suicide occurring in construction workers in Australia. We randomly selected 34 cases according to specific sampling framework. Thematic analysis was used to develop a coding structure on the basis of pre-existing theories in job stress research. RESULTS: The following themes were established on the basis of mutual consensus: mental health issues prior to death, transient working experiences (i.e., the inability to obtain steady employment), workplace injury and chronic illness, work colleagues as a source of social support, financial and legal problems, relationship breakdown and child custody issues, and substance abuse. CONCLUSION: Work and non-work factors were often interrelated pressures prior to death. Suicide prevention for construction workers needs to take a systematic approach, addressing work-level factors as well as helping those at-risk of suicide.

Suicide by health professionals: a retrospective mortality study in Australia, 2001-2012.

OBJECTIVES: To report age-standardised rates and methods of suicide by health professionals, and to compare these with suicide rates for other occupations. STUDY DESIGN: Retrospective mortality study. SETTING, PARTICIPANTS: All intentional self-harm cases recorded by the National Coronial Information System during the period 2001-2012 were initially included. Cases were excluded if the person was unemployed at the time of death, if their employment status was unknown or occupational information was missing, or if they were under 20 years of age at the time of death. Suicide rates were calculated using Australian Bureau of Statistics population-level data from the 2006 census. MAIN OUTCOME MEASURES: Suicide rates and method of suicide by occupational group. RESULTS: Suicide rates for female health professionals were higher than for women in other occupations (medical practitioners: incidence rate ratio [IRR], 2.52; 95% CI, 1.55-4.09; P < 0.001; nurses and midwives: IRR, 2.65; 95% CI, 2.22-3.15; P < 0.001). Suicide rates for male medical practitioners were not significantly higher than for other occupations, but the suicide rate for male nurses and midwives was significantly higher than for men working outside the health professions (IRR, 1.50; 95% CI 1.12-2.01; P = 0.006). The suicide rate for health professionals with ready access to prescription medications was higher than for those in health professions without such access or in non-health professional occupations. The most frequent method of suicide used by health professionals was self-poisoning. CONCLUSION: Our results indicate the need for targeted prevention of suicide by health professionals.

Assessing Parental Knowledge About Thalassemia in a Thalassemia Center of Karachi, Pakistan.

Thalassemia is the leading haemoglobinopathy after sickle cell anemia that accounts for 1.5 % of the global population. In Pakistan, every 1-4 per 1000 infants suffers from Thalassemia. Regardless of being a population "at high risk" for Thalassemia major, evidence suggest that Pakistanis possess poor knowledge of the disease. The present study aimed to assess parents' accurate knowledge about Thalassemia disease at Afzaal Memorial Thalassemia Foundation in Karachi, Pakistan. A total of 172 parents of existing patients who were receiving regular blood transfusion from the center were included in the study. Parents' knowledge was assessed via a pre-tested and validated Thalassemia knowledge questionnaire. Findings show that 40 % of the sample showed lower knowledge scores about Thalassemia. Among different ethnic origins, Urdu speaking respondents showed a higher average score of correct knowledge about Thalassemia major (21.6 ± 4.41) as compared to the Siraiki (17.9 ± 4.48) and the Pathans (17.2 ± 4.34). These latter two ethnic groups also showed poor knowledge about Thalassemia minor. Generally parents provided correct answers about treatment of Thalassemia major. The findings suggest targeted interventions are required for high risk ethnic groups. Thalassemia education programs should be offered to extended family members of existing patients by all Thalassemia centers. High risk ethnic groups (Siraiki and Pathan) need rigorous interventions, and Thalassemia worker program should be introduced nationwide.

Risk factors for intraventricular haemorrhage in preterm infants from a tertiary care hospital of Karachi, Pakistan.

OBJECTIVE: To determine the incidence of Intraventricular Haemorrhage in pre-term infants, along with adverse neonatal outcomes associated with the disease. METHODS: The retrospective case control study was conducted at Aga Khan University Hospital, Karachi, and comprised patients' records from January 2004 to December 2009 of preterm babies from 26-35 weeks of gestation who had Intraventricular Haemorrhage of any grade. The diagnosis was confirmed by ultrasound scan. Controls were preterm births matched with the cases according to gestational age (±1 week) and birth weight (±150 grams). SPSS 19 was used for statistical analysis. RESULT: Of the total 201 preterm babies in the study, there were 67(33.33%) cases and 134(66.66%) controls; the respective ratio being 1:2.The incidence of Intraventricular Haemorrhage in the study population was 22.1 per 1000 live births.The odds of developing Intraventricular Haemorrhage was substantially higher in babies with respiratory distress syndrome (odds ratio: 3.77; 95% Confidence Interval: 1.52-9.37; p < 0.004) and who were given mechanical ventilation (odds ratio: 23.6; 95% Confidence Interval: 5.09-109.5; p < 0.001). There was a four-fold increase in risk of Intraventricular Haemorrhage in babies who received surfactant administration (odds ratio: 4.26; 95% Confidence Interval: 1.77-10.22; p < 0.001). Out of 67 cases, 50 (74.6%) re-demonstrated the same grade, 13 (19.4%) were resolved, and 4 (6%) progressed. Overall, there were 38 death; the mortality rate being 56.71. CONCLUSION: The risk of Intraventricular Haemorrhage was substantially higher in preterm neonates with respiratory distress syndrome, etc., and the mortality rate was higher in babies with severe disease.

Suicidal Behavior of Australian Males, From an Ethnicity Perspective.

BACKGROUND: Suicide is the 10th leading cause of death among Australian males. Despite the cultural diversity in Australia, there is a significant research gap in knowledge of suicidal behavior among Australian males from ethnically and culturally diverse backgrounds. The study aimed to estimate the prevalence and risk of suicidal behaviors among Australian males based on ethnicity, with an emphasis on those from ethnic-minority backgrounds. METHODS: We used data from the first wave of the Australian Longitudinal Study on Male Health. Multiple logistic regression models were used to determine the risk of suicidal behavior (lifetime suicide attempt, lifetime suicidal ideation, recent suicidal ideation) by ethnicity. RESULTS: Among ethnic minority males, Pacific Islander males also had the highest prevalence of lifetime suicide attempts (12.2%), while Middle Eastern (2.3%) and South-/North-East Asian males (2.9%) had the lowest rates. South American males had the highest recent suicidal ideation (18.2%), followed by Pacific Islanders (14.2%). The highest prevalence of lifetime suicidal thoughts was reported among males of mixed ethnicity (23.0%), followed by South American (14.6%) and Pacific Islander (13.5%) males. Most ethnic-minority groups had a lower risk of lifetime suicidal ideation compared with Australian males. Evidence regarding differences in recent suicidal ideation and lifetime suicide attempts between ethnic-minority and Australian-background males was inconclusive. CONCLUSION: Evidence was found of differences in suicidal behaviors among Australian males based on ethnicity. Future research should use inclusive methodologies to confirm these associations and explore the underlying factors contributing to higher rates of suicidal behavior in specific populations.

Mental health impacts from repeated climate disasters: an australian longitudinal analysis.

Background: Extreme weather events are becoming more frequent and intense under changing climatic conditions. Whilst there is substantial evidence that exposure to a single weather related disaster is detrimental for mental health, few studies have explored how exposure to multiple disasters impacts mental health. Methods: We utilised 11 waves of data from the Household, Income and Labour Dynamics in Australia (HILDA) Survey, yielding a sample of 16,629 observations from 2003 individuals. Fixed effects linear regression analysis was used to estimate the impact of experiencing multiple disasters on mental health. We tested for effect modification on this association by sex, rurality, employment and presence of a long-term health condition. Findings: Exposure to multiple disasters was associated with a relative decrease in MHI-5 score compared to baseline by -1.8 points (95% CI -3.4, -0.3), whereas exposure to a single disaster was not associated with a decline in mental health scores. There was evidence of effect modification by employment status. Unemployed individuals had evidence of moderate reduction in MHI-5 scores when exposed to a single disaster (-4.3, 95% CI -7.0, -1.5). Interpretation: Findings suggest that repeat exposure to disasters is associated with worsening mental health outcomes. As extreme weather events increase, these findings highlight the need for greater attention on climate change action, and mental health interventions targeting impacted populations.

Unpaid caregiving and mental health during the COVID-19 pandemic-A systematic review of the quantitative literature.

The COVID-19 pandemic imposed additional and specific challenges on the lives and wellbeing of informal unpaid carers. Addressing an important gap in the existing literature, this systematic review (prospectively registered with PROSPERO CRD42022376012) synthesises and evaluates the quantitative evidence examining the association between unpaid caregiving and mental health (compared to non-caring), during the pandemic. Five databases were searched (Medline, PsycInfo, EMBASE, Scopus, Web of Science) from Jan 1, 2020, to March 1, 2023. Population-based, peer-reviewed quantitative studies using any observational design were included, with screening, data extraction and quality assessment (amended NOS) independently conducted by two reviewers. Of the 3,073 records screened, 20 eligible studies (113,151 participants) were included. Overall quality of evidence was moderate. Narrative synthesis was complemented by Effect-direction and Albatross plots (given significant between-study heterogeneity precluded meta-analysis). Results indicate that the mental health of informal carers, already poorer pre-COVID compared to non-caregivers, was disproportionally impacted as a result of the pandemic and its associated public health containment measures. This review highlights the vulnerability of this group and should motivate political will and commensurate policies to ensure unpaid caregivers are better supported now, in the medium term, and crucially if, and when, another global public health emergency emerges.

Impact of informal caregiving on depressive symptoms among a national cohort of men.

BACKGROUND: There is evidence that unpaid caregiving can have negative effects on the mental health of female caregivers; however, evidence of impacts on male caregivers is limited. This study addressed this gap by examining associations between becoming a caregiver and depressive symptoms among men. METHODS: We used data from waves 1-2 (2013, 2016) of the Longitudinal Study of Australian Male Health (Ten to Men). Effects of incident caregiving on depressive symptoms were estimated using augmented inverse probability treatment weighting, with adjustment for potential confounders. Incident caregiving was assessed as a binary variable (became a caregiver vs not), and depressive symptoms were measured using the Patient Health Questionnaire (moderate to severe depressive symptoms; yes, no). Main analysis was prospective, drawing on wave 1 (caregiving) and wave 2 (depressive symptoms), and sensitivity analyses modelled cross-sectional associations. RESULTS: In the main analysis, incident caregiving in wave 1 was associated with depressive symptoms in the subsequent wave, with an average treatment effect of 0.11 (95% CI 0.06, 0.17) and equating to a risk ratio of 2.03 (95% CI 1.55, 2.51). Associations were robust to several sensitivity analyses, with cross-sectional associations supporting the main prospective analyses. CONCLUSION: These results provide evidence of the association between caregiving and depressive symptoms among male caregivers. This has important implications for policy and support programmes. As we seek to shift caregiving responsibilities toward a more gender-equal distribution of care, policy must recognise that, like female caregivers, male caregivers also experience mental health impacts related to their caregiving role.

Suicide in first-generation Australian migrants, 2006-2019: a retrospective mortality study.

Background: This study addressed the limited understanding of suicide risk and patterns among migrants in Australia. It examined national-level suicide rates and trends in the Australian population to identify migrant groups which are disproportionately affected by suicide. Methods: The National Coronial Information System was used to identify suicide cases from 2006 to 2019. Incident rate ratios (IRR) with 95% confidence intervals (CI) evaluated suicide risk for migrant groups compared to Australian-born and migrants from English-speaking countries. Age-standardised suicide rates (ASR) per 100,000 and average annual percentage change (AAPC) were calculated to compare suicide rates and trends. Findings: Compared to the Australian-born population, all migrant males and females had significantly lower suicide risk, except females from Oceania countries. Females from European (IRR 1.28, 95% CI 1.13, 1.14) and Oceanian countries (IRR 1.25; 95% CI 0.95, 1.66) had an elevated suicide risk compared to female migrants from English-speaking countries. Male migrants from Oceania (ASR 20.4, AAPC 1.0 (-3.6, 5.8)) and Africa (ASR 18.0, AAPC -0.4 (-5.5, 4.9)) have high ASR with no significant changes in trend over the study duration. Female African migrants had an ASR of 5.3 per 100,000, which increased by 8% (95% CI 1.4, 15.0) between 2006 and 2019. Interpretation: Migrants from Oceania and African countries are disproportionately affected by suicide mortality compared to other migrant groups in Australia. Further research is needed to identify the risk factors and develop suicide prevention strategies for these groups. Funding: Suicide Prevention Australia, Australian Research Council.

Suicide in the Australian Mining Industry: Assessment of Rates among Male Workers Using 19 Years of Coronial Data.

Background: International evidence shows that mining workers are at greater risk of suicide than other workers; however, it is not known whether this applies to the Australian mining sector. Methods: Using data from the National Coronial Information System, rates of suicide among male mining workers were compared to those of three comparators: construction workers, mining and construction workers combined, and all other workers. Age-standardized suicide rates were calculated for 2001-2019 and across three intervals '2001-2006', '2007-2011', and '2012-2019'. Incidence rate ratios for suicide were calculated to compare incidence rates for mining workers, to those of the three comparative groups. Results: The suicide rate for male mining workers in Australia was estimated to be between 11 and 25 per 100,000 (likely closer to 25 per 100,000) over the period of 2001-2019. There was also evidence that the suicide rate among mining workers is increasing, and the suicide rate among mining workers for the period 2012-2019 was significantly higher than the other worker group. Conclusions: Based on available data, we tentatively deduce that suicide mortality among male mining workers is of concern. More information is needed on both industry and occupation of suicide decedents in order to better assess whether, and the extent to which, mining workers (and other industries and occupations) are at increased risk of suicide.
