Occupation, work-related stress, and personal characteristics among suicide deaths with occupation-related compensation claims in Korea.

OBJECTIVES: This study compared differences in age-standardized suicide mortality rates, personal characteristics (demographics, employment conditions, and details of suicide), and work-related stress by gender and occupation among workers who had committed suicide in Korea. METHODS: Data comprised 413 suicide death claims lodged with the Industrial Accident Compensation Insurance (IACI) from 2010 to 2018, which were coded. We calculated age-standardized suicide mortality rates by gender and occupation. The chi-square test, Fisher's exact test, and t-test were conducted to examine gender differences. Frequency and percentage distribution by gender and occupation were calculated using descriptive statistics. RESULTS: Regardless of gender, age-standardized suicide mortality rate was highest among "Managers." Women who died by suicide were significantly younger and more likely to be unmarried, live alone, and have fewer years of continuous employment than men. "Managers," "Professionals and Related Workers," and "Clerks" experienced similar work-related stresses, including "Difficult work to achieve," "Fail to achieve allocation workload," and "Change of job contents or workload." "Skilled Agricultural, Forestry and Fishery Workers," "Craft and Related Trades Workers," and "Equipment, Machine Operating and Assembling Workers" had higher work-related stress related to "Severe disease/injury" or "Causing a serious accident" compared with other workers. CONCLUSIONS: Work-related stress related to suicide deaths differed by gender and occupation. The gender gap of labor market participation in Korea may affect gender differences in terms of demographics and employment conditions among workers who died by suicide. Our study suggests that gender- and occupation-specific strategies and policies to reduce work-related stress can prevent suicide among workers.

The Uncounted Casualties of a Hidden COVID-19 Epidemic in China: Cross-sectional Study on Deaths Related to Overwork.

BACKGROUND: During the COVID-19 response, nonclinical essential workers usually worked overtime and experienced significant work stress, which subsequently increased their risk of mortality due to cardiovascular diseases, stroke, and pre-existing conditions. Deaths on duty, including deaths due to overwork, during the COVID-19 response were usually reported on web-based platforms for public recognition and solidarity. Although no official statistics are available for these casualties, a list of on-duty deaths has been made publicly available on the web by crowdsourcing. OBJECTIVE: This study aims to understand the trends and characteristics of deaths related to overwork among the frontline nonclinical essential workers participating in nonpharmaceutical interventions during the first wave of COVID-19 in China. METHODS: Based on a web-based crowdsourced list of deaths on duty during the first wave of the COVID-19 response in China, we manually verified all overwork-related death records against the full-text web reports from credible sources. After excluding deaths caused by COVID-19 infection and accidents, a total of 340 deaths related to overwork among nonclinical essential workers were attributed to combatting the COVID-19 crisis. We coded the key characteristics of the deceased workers, including sex, age at death, location, causes of death, date of incidence, date of death, containment duties, working area, and occupation. The temporal and spatial correlations between deaths from overwork and COVID-19 cases in China were also examined using Pearson correlation coefficient. RESULTS: From January 20 to April 26, 2020, at least 340 nonclinical frontline workers in China were reported to have died as a result of overwork while combatting COVID-19. The weekly overwork mortality was positively correlated with weekly COVID-19 cases (r=0.79, P<.001). Two-thirds of deceased workers (230/340, 67.6%) were under 55 years old, and two major causes of deaths related to overwork were cardiovascular diseases (138/340, 40.6%) and cerebrovascular diseases (73/340, 21.5%). Outside of Hubei province, there were almost 2.5 times as many deaths caused by COVID-19-related overwork (308/340, 90.6%) than by COVID-19 itself (n=120). CONCLUSIONS: The high number of deaths related to overwork among nonclinical essential workers at the frontline of the COVID-19 epidemic is alarming. Policies for occupational health protection against work hazards should therefore be prioritized and enforced.

COVID-19 related suicide among hospital nurses; case study evidence from worldwide media reports.

Nurses are acknowledged for their care and expertise on the front line of pandemics over the last century. The recent global impact of COVID-19 has been unprecedented and a parallel battle has also been fought by increasing numbers of nurses for their workplace mental health. Factors associated with nurses mental stress and consequence of suicide were identified from a retrospective analysis of six non-representative media case-reports in high and low resource countries. The need for a structured model of nursing workforce mental health preparation, monitoring, support and health care is essential to inform advocacy and timely intervention in pandemic response.

Psychosocial work exposures of the job strain model and cardiovascular mortality in France: results from the STRESSJEM prospective study.

Objectives The study aims to explore the prospective associations of the psychosocial work exposures of the job strain model with cardiovascular mortality, including mortality for ischemic heart diseases (IHD) and stroke, using various time-varying exposure measures in the French working population of employees. Methods The study was based on a cohort of 798 547 men and 697 785 women for which job history data from 1976 to 2002 were linked to mortality data and causes of death from the national death registry. Psychosocial work exposures from the validated job strain model questionnaire were assessed using a job-exposure matrix (JEM). Three time-varying measures of exposure were studied: current, cumulative, and recency-weighted cumulative exposure. Cox proportional hazards models were used to examine the associations between psychosocial work exposures and cardiovascular mortality. Results Within the 1976-2002 period, there were 19 264 cardiovascular deaths among men and 6181 among women. Low decision latitude, low social support, job strain, iso-strain, passive job, and high strain were associated with cardiovascular mortality. Most of these associations were also observed for IHD and stroke mortality. The comparison between the different exposure measures suggested that current exposure may be more important than cumulative (or past) exposure. The population fractions of cardiovascular mortality attributable to job strain were 5.64% for men and 6.44% for women. Conclusions Psychosocial work exposures of the job strain model may play a role in cardiovascular mortality. The estimated burden of cardiovascular mortality associated with these exposures underlines the need for preventive policies oriented toward the psychosocial work environment.

Psychosocial work stressors and risk of mortality in Australia: analysis of data from the Household, Income and Labour Dynamics in Australia survey.

OBJECTIVE: To examine the association between exposures to psychosocial work stressors and mortality in a nationally representative Australian working population sample. METHODS: 18 000 participants from the Household, Income and Labour Dynamics in Australia survey with self-reported job demands, job control, job security and fair pay psychosocial work stressors exposures at baseline were followed for up to 15 waves. Cox proportional hazards regression models were used to examine the association between psychosocial work stressors and mortality. Models were serially adjusted for each subgroup of demographic, socioeconomic, health and behavioural risk factors. RESULTS: Low job control was associated with a 39% increase in the risk of all-cause mortality (HR 1.39; 95% CI 1.04 to 1.85), controlling for demographic, socioeconomic, health and behavioural factors. A decreased risk of mortality was observed for workers with exposure to high job demands (HR 0.76; 95% CI 0.60 to 0.96, adjusted for gender and calendar), but the risk was attenuated after serially adjusting for socioeconomic status, health (HR=0.84; 95% CI 0.65 to 1.08) and behavioural (HR=0.79; 95% CI 0.60 to 1.04) factors. There did not appear to be an association between exposure to job insecurity (HR 1.03; 95% CI 0.79 to 1.33) and mortality, or unfair pay and mortality (HR 1.04; 95% CI 0.80 to 1.34). CONCLUSIONS: Low job control may be associated with an increased risk of all-cause mortality. Policy and practice interventions that reduce the adverse impact of low job control in stressful work environments could be considered to improve health and decrease risk of mortality.

Deaths in Australia from Work-Related Heat Stress, 2000-2015.

The infrequency of deaths from work-related heat stress may be due to self-pacing, whereby workers adjust their work rate in response to thermal discomfort. Thirteen cases attributed after coronial investigation to work-related heat stress were studied to evaluate the causal contribution of environmental and personal risk factors. Meteorological records and coronial records were examined to estimate environmental and metabolic heat loads and to identify any personal risk factors likely to have contributed to death. Seven deaths occurred in workers within one week of hiring, demonstrating not only the importance of acclimatisation but also the likelihood of compromised self-pacing in recently-hired workers. Personal risk factors identified included intercurrent illness, cardiovascular disease and obesity. Four deaths occurred following indoor work, where the probable critical risk parameter was low air velocity. Cerebral and pulmonary oedema were reported in some autopsy reports, and uncal herniation was found in one case. Modified work rates and close supervision are essential in recently-hired workers. The risk of death from raised intracranial pressure suggests the need for specific remediation of cerebral oedema in hyperthermic individuals.

Suicide Mortality Patterns in Greek Work Force before and during the Economic Crisis.

Background: The global recession of 2007 has attracted research attention in regard to a possible increase of deaths by suicide among employed populations. The aim of the current study was to update the first Greek study on suicide mortality among broad occupational groups during 2000⁻2009, with the last available data covering the first period of economic crisis and recession in Greece. Methods: Data on suicide deaths for the age groups of 15⁻39, 40⁻49 and 50⁻59, between 2000⁻2013 were retrieved from the national statististical authority of Greece, ELSTAT. The coding of suicide used was X60⁻X84 (intentional self-harm), based on the 10th International Classification of Diseases (ICD-10). Comparative mortality ratio (CMR) and exact 95% confidence intervals (CI) are presented. Results: Males and females in the occupational group of clerks exhibited high and increased CMRs during the crisis period (2010⁻2013). Although high ratios for males in elementary, agricultural and fishery and armed forces occupational groups were monitored during the whole period, a decrease was evident during the crisis period. Increased trends in CMRs during the crisis were monitored for both males and females in the broad occupational group of members including managers, executives and directors. In addition, females especially in the 50⁻59 age group showed increased ratios and trends in several occupational groups during the crisis, especially in technologists and associate professionals, plant and machine operators and assemblers, professionals, and craft and related trade workers. Conclusions: Austerity-related stress should alert key stakeholders and provide mental health and suicide prevention interventions for employed occupations.

Men's work, women's work and suicide: a retrospective mortality study in Australia.

OBJECTIVES: This research sought to investigate the influence of being a in male-dominated occupation on suicide. METHODS: A population-level retrospective mortality study was conducted over the period 2001 to 2015. Data from the Australian Census and the National Coronial Information System were combined. Negative binomial regression was used to assess the relationship between occupational gender ratio and suicide rates, controlling for age, socioeconomic status and year of death. Probabilistic sensitivity analysis accounted for unmeasured confounding due to common mental disorders. RESULTS: Males in male-dominated occupations had a rate ratio (RR) of 7.50 (95%CI 6.07 to 9.25) compared to males in female-dominated occupations. Females in male-dominated occupations had a RR of 0.13 (95%CI 0.07 to 0.26) compared to females in female-dominated occupations. Results for males were maintained after adjusting for common mental disorders. There was evidence of interaction on both additive and multiplicative scales. CONCLUSIONS: The gendered context of an occupation influences suicide, with varying risks for women and men. More research is needed to understand the mechanisms of this relationship. Implications for public health: These results suggest the need for targeted suicide prevention activities in male-dominated occupational groups.
