Relation between occupation, gender dominance in the occupation and workplace and suicide in Sweden: a longitudinal study

Occupational groups and risk of suicidal behavior in men: a Swedish national cohort study during 2002-2019

INTRODUCTION

The risk of suicide has been shown to vary by occupation. We aim to identify contemporary occupational groups at greatest risk for suicidal behaviour (fatal and non-fatal), in Swedish men of working-age.

METHODS

A population-based cohort study of male conscripts without history of self-harm who enlisted during 1968-2001 and were followed-up during 2002-2019 (n = 1 542 665). Occupational groups and suicidal behaviours were identified using national registers. Incidence rate ratios (IRR) for suicidal behaviour at ages 25-65 were calculated among occupational groups, and compared to the incidence rate of the whole cohort.

RESULTS

Major occupational groups with increased risk for suicidal behavior included elementary occupations, building and manufacturing, service, care and shop sale and mechanical manufacturing and transport. Subgroup analyses revealed particularly high risks for assistant nurses, other service workers not elsewhere classified, building frame and related trades workers and cleaners and helpers.

CONCLUSIONS

Men with elementary occupations as well as personal care and building and manufacturing workers were at greatest risk. This study provides a comprehensive description of risks for suicidal behaviour among occupational groups in men of working-age. These results suggest occupational groups that should be targeted for general suicide prevention intervention.

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.

High overcommitment and low reward as potential predictors for increased depressive symptoms, suicidal ideation, and suicide risk in German veterinarians

Higher rates of depression, suicidal ideation and suicide risk have been reported for veterinarians in Germany. In this study, several demographic and job-related factors were examined to determine whether they could be considered possible predictors of depression, suicidal ideation, and suicide risk. For this purpose, a survey was conducted among veterinarians in Germany. The demographic factors surveyed were gender, age, working status (employed/self-employed), income, field of work (practicing/non-practicing veterinarian), weekly working hours and community size. For assessing job-related factors, the Effort-Reward-Imbalance questionnaire (effort, reward, overcommitment), several subscales of the Copenhagen Psychosocial Questionnaire (quantitative demands, emotional demands, demands for hiding emotions, meaning of work, work-privacy-conflict, thoughts of leaving the job) and the Copenhagen Burnout Inventory were used. A hierarchical logistic regression analysis was performed with the demographic and job-related factors as independent variables and depressive symptoms, suicidal ideation, and suicide risk as dependent variables, respectively. A total of 3.118 veterinarians (78.8% female) between 22 and 69 years (mean age 41.3 years) were included in the study. The factors used resulted in the highest variance explanation for depressive symptoms (57%), followed by suicidal ideation (34%) and suicide risk (23%). Low reward and high overcommitment were found to be the most important predictors of depressive symptoms, suicidal ideation, and suicide risk. Significant relationships with depressive symptoms, suicidal ideation, and suicide risk were also found for burnout, demands for hiding emotions, and thoughts of leaving the job. The results of this study point to opportunities for changes in the veterinary working environment, for the development of prevention and intervention programs for veterinarians, and for the further development of the veterinary curriculum to strengthen the mental health of veterinarians in Germany.

Perceptions of mental health, suicide and working conditions in the construction industry-A qualitative study

OBJECTIVE

The aim of the study was to explore perceptions of mental ill health, suicidal behaviour and working conditions among male construction workers, in order to gain an in-depth understanding of these phenomenon and to identify relevant avenues for workplace interventions.

METHOD

Data were collected in individual and group interviews, and 43 individuals from the Swedish construction industry, workers, union representative and managers, participated in the study. Inductive thematic analysis was used to analyse the data.

RESULTS

Five main themes were found: Difficult to talk about mental health, Demanding working environment affects mental health, Substance abuse among construction workers, Importance of management, and Need for routines and social support in the workplace. Many participants reported that there was a stigma related to mental health. Suicides that had occurred among colleagues were perceived to come out of the blue. The working environment in the construction industry was perceived to have a negative effect on mental health, and it was reported that the management played an important role in both the cause and prevention of mental health problems.

CONCLUSIONS

The results from this Swedish study are in accordance with previous international research regarding a macho culture, stigma of mental health and a demanding working environment in the construction industry. The study adds to existing knowledge by highlighting that suicides were perceived to be very unexpected, that poor physical health affected mental health and that many participants did not know how to deal with mental health issues in the workplace.

Diagnoses of common mental disorders among social workers in Sweden: A register-based cohort study

BACKGROUND

Little is known about common mental disorders (CMD) diagnoses among social workers, i.e., depression, anxiety, or stress-related disorders. This study aims to examine the risk of CMD among social workers in comparison to other workers and to further investigate differences between men and women and specific occupational titles.

METHODS

This register-based cohort study consists of 3,034,304 persons, of which 26,610 were social workers (0.9 % of all workers), aged 30-64 years, living in Sweden in 2015. The risk of diagnosed CMDs was followed up until 2020. Cox regression models were used to calculate hazard ratios (HR) and 95 % confidence intervals (CI), adjusting for sex, birth country, education, and birth year.

RESULTS

The participants were followed up by a total of 16,833,742.9 person-years, with an average follow-up of 5.5 years. Social workers, compared to other workers, were at a higher risk of CMD (HR 1.3, 95 % CI 1.2-1.4) after adjustment. The HR was equal, 1.3, for depression (95 % CI 1.2-1.5) and anxiety or stress-related disorder (95 % CI 1.2-1.4). The association between social work and CMD was stronger among men (HR 1.7, 95 % CI 1.6-1.9) compared to women (HR 1.2, 95 % CI 1.1-1.3). Further, men working as assistance analysts had the highest risk among the occupational categories (HR 2.2, 95 % CI 1.2-3.9).

LIMITATIONS

CMD diagnoses only included cases treated in secondary care.

CONCLUSIONS

Social workers, especially male social workers, had a higher risk of CMD. This deserves attention for future research and interventions aimed at improving the mental health of social workers.

Workplace interventions to prevent suicide: A scoping review

OBJECTIVES

To map organisational interventions for workplace suicide prevention, identifying the effects, mechanisms, moderators, implementation and economic costs, and how interventions are evaluated.

BACKGROUND

Suicide is a devastating event that can have a profound and lasting impact on the individuals and families affected, with the highest rates found among adults of work age. Employers have a legal and ethical responsibility to provide a safe working environment for their employees, which includes addressing the issue of suicide and promoting mental health and well-being.

METHODS

A realist perspective was taken, to identify within organisational suicide prevention interventions, what works, for whom and in what circumstances. Published and unpublished studies in six databases were searched. To extract and map data on the interventions the Effect, Mechanism, Moderator, Implementation, Economic (EMMIE) framework was used. Mechanisms were deductively analysed against Bronfenbrenner's socio-ecological model.

RESULTS

From 3187 records screened, 46 papers describing 36 interventions within the military, healthcare, the construction industry, emergency services, office workers, veterinary surgeons, the energy sector and higher education. Most mechanisms were aimed at the individual's immediate environment, with the most common being education or training on recognising signs of stress, suicidality or mental illness in oneself. Studies examined the effectiveness of interventions in terms of suicide rates, suicidality or symptoms of mental illness, and changes in perceptions, attitudes or beliefs, with most reporting positive results. Few studies reported economic costs but those that did suggested that the interventions are cost-effective.

CONCLUSIONS

It seems likely that organisational suicide prevention programmes can have a positive impact on attitudes and beliefs towards suicide as well reducing the risk of suicide. Education, to support individuals to recognise the signs and symptoms of stress, mental ill health and suicidality in both themselves and others, is likely to be an effective starting point for successful interventions.

Euthanasia of animals - association with veterinarians' suicidal thoughts and attitudes towards assisted dying in humans: a nationwide cross-sectional survey (the NORVET study)

BACKGROUND

Veterinarians are an occupational group with an increased suicide risk. Euthanasing animals may influence both veterinarians' views on assisted dying in humans and their suicide risk. We investigated (I) attitudes towards assisted dying, (II) whether the field of work and the frequency of euthanasing animals were associated with positive attitudes towards human euthanasia, and (III) whether frequently euthanasing animals was associated with serious suicidal thoughts.

METHODS

We conducted a nationwide cross-sectional study among veterinarians in Norway (response rate: 75%). Logistic regression models were used to calculate the odds ratios for both positive attitudes towards human euthanasia and serious suicidal thoughts. The analyses were adjusted for socio-demographic and work-related factors.

RESULTS

Fifty-five percent of the veterinarians agreed that euthanasia should be permitted for humans with a fatal disease and short life expectancy. Working with companion animals was independently associated with positive attitudes towards human euthanasia (OR = 1.66 (95% CI: 1.23-2.23)), while veterinarians' frequency of euthanasing animals was not. Frequency of euthanasing animals was independently associated with serious suicidal thoughts, OR = 2.56 (95% CI: 1.35-4.87).

CONCLUSIONS

Veterinarians' attitudes towards assisted dying in humans did not differ from those of the general population. Veterinarians' frequency of euthanasing animals was not associated with positive attitudes towards euthanasia in humans. However, veterinarians working in companion animal practices were more likely to have positive attitudes towards euthanasia in humans. Moreover, euthanising animals five times or more a week was associated with serious suicidal thoughts. We need more research to infer about causality in these findings.

Risk of suicide and self-harm in university students entering different university programs - a national register-based cohort study in Sweden

PURPOSE

It is not known whether the elevated suicide risk in certain occupations, such as health care professionals, is partly attributable to a selection of individuals with prior vulnerability. We aimed to determine the risk of suicide and self-harm already in students entering different university programs.

METHODS

We used national registers to identify 621,218 Swedish residents aged 18-39 years with registration for a university program 1993-2013. Outcomes were suicide and self-harm within three years. We applied logistic regression analyses to calculate odds ratios (OR) and 95% confidence intervals (CI) of risk of suicide and self-harm, with the Education program category as a reference. Results were adjusted for sex, age, time period and for history of hospitalization due to mental disorder or self-harm, as a measure of previous vulnerability. In the second step, we stratified results by sex.

RESULTS

There was a higher risk of suicide (OR 2.4) in female nursing students and natural science students (OR 4.2) and of self-harm in female and male Nursing/Health care students (OR range 1.2 -1.7). Subcategorization into nursing students only strengthened the association with self-harm for both sexes. Prior vulnerability did not fully explain the increased risk.

CONCLUSION

The elevated risk of suicide in nursing and health care occupations partly has its onset in vulnerability factors present before or emerging during university studies. Increased efforts in identifying and treating mental disorders and preventing self-harm in university students could be an important step in preventing future suicides.
