The associations of psychosocial work exposures with suicidal ideation in the national French SUMER study

BACKGROUND

The literature remains scarce on the work-related risk factors for suicide and suicidal ideation. The objectives were to explore the associations of psychosocial work exposures with suicidal ideation in a nationally representative sample of the working population.

METHODS

The study was based on the sample of 25,977 employees (14,682 men and 11,295 women) of the national French 2016-17 SUMER survey. The outcome was suicidal ideation assessed using the PHQ-9 instrument. Psychosocial work exposures included various factors from the job strain and effort-reward imbalance models, and other concepts. Statistical analyses were performed using weighted methods, including weighted logistic regression models. Other occupational exposures and covariates were considered. Gender differences were tested.

RESULTS

The prevalence of suicidal ideation was 3.5 % without any difference between genders. Psychosocial work exposures were found to be associated with suicidal ideation. The strongest association was observed between workplace bullying and suicidal ideation. Associations were also found between job strain model factors, job insecurity, low esteem, work-family conflict, ethical conflict, teleworking, and low meaning, and suicidal ideation. The associations were in general similar for men and women.

LIMITATIONS

The study had a cross-sectional design and no causal interpretation could be done. A reporting bias and a healthy worker effect may be suspected.

CONCLUSION

Psychosocial work exposures played a major role in suicidal ideation. More research may be needed to confirm our results, as suicidal ideation is an important warning signal for suicide prevention. More primary prevention towards the psychosocial work environment may be useful to reduce suicidal ideation at the workplace.

Part-time work and sickness absence - an organization-level analysis

BACKGROUND

Absenteeism is consistently higher in public than in private organizations, as is the use of part-time employment. The aim of this study is to identify whether there is a relationship between part-time work and sickness absence at the organizational level.

METHODS

The data is a six-year panel for the full population of Norwegian municipalities (N = 422), linking objective register data on both part-time employment and sickness absence. Using OLS regression with fixed effects for municipality and time, we estimate the statistical effects of the municipalities' use of part-time work on sickness absence.

RESULTS

The bivariate correlation between percentage position at the municipal level and percentage sickness absence is positive and significant (Pearson's r = .25, sig LE 0.01). When controlling for fixed effects for municipality and time, as well as municipality economy, municipality size, ratio of female employees in the municipality and characteristics of the general population, the multivariate regression coefficient is still positive but insignificant (coefficient = 1.56, robust standard error = 1.31).

CONCLUSIONS

The main findings are that the organizations' use of part-time work is unrelated to sickness absence indicating that organizations with extensive use of part-time work do not experience higher levels of absenteeism than those having less extensive use of part-time employees.

Becoming the employer of choice: anticipating and preparing for a graying workforce in industry

The recent shift in the labor force that has occurred in many developed countries has been greater than any shift prior to 2020. This shift was caused by reduced birthrates coupled with the rising percentage of mature workers in the labor force, compounded by the 2020 global shut-down due to Covid-19. Managers and HR directors need to act now to gather the necessary data on their employees and their company’s projected labor needs to accurately plan for their short- and long-term labor needs. A partial solution for this impending labor shortage is for companies to proactively become the “employer of choice” for their graying workforce by making necessary accommodations to retain and recruit mature workers. The concept of employer of choice relates to creating a work climate that attracts and retains workers to a specific employment opportunity. This article focuses on the steps that can be taken by employers to minimize the impact of this looming labor shortage on their company as well as on the overall economy. The article also provides background on some of the reasons why many mature workers want and need to continue working and the imperatives as to why immediate action on the part of employers is necessary.

Shift and Night Work and All-Cause and Cause-Specific Mortality: Prospective Results From the STRESSJEM Study

The literature remains sparse and inconclusive about the impact of shift and night work on mortality, and still more on specific causes of death. The objectives were to explore the prospective associations between exposure to shift and night work and all-cause and cause-specific mortality. The study was based on a large national representative French prospective cohort of 1,511,456 employees followed up from 1976 to 2002. Exposure to shift and night work relied on a job-exposure matrix, and 3 time-varying measures (current, cumulative, and recency-weighted cumulative exposure) were constructed. Mortality and causes of death were provided by the national registry, and all-cause, cardiovascular, cancer and preventable mortality, and suicide were studied. Cox proportional hazards models were performed to study the associations between shift and night work and mortality. During follow-up, 22,105 deaths occurred for all-cause mortality. In the study of mortality until the end of last job during follow-up, shift and/or night work were associated with all-cause, cardiovascular, cancer and preventable mortality, and suicide (except night without shift work with cancer mortality and suicide) among men. Shift work (especially shift without night work) was associated with all-cause, cancer and preventable mortality among women. The results were similar for current, cumulative, and recency-weighted cumulative exposure. Associations were found for more detailed causes of death: cerebrovascular diseases for both genders, ischemic heart diseases, respiratory cancers, smoking-related mortality, and external causes of death among men, and breast cancer among women. In the study of mortality until the end of follow-up, some additional associations were found among women between night work and all-cause and preventable mortality, and suicide, suggesting long-term or delayed exposure effects. The study may, however, be underpowered to detect all the exposure-outcome associations, especially among women. More research and prevention are needed to reduce mortality among shift and night workers.

Association of perceived work pace and physical work demands with occupational accidents: a cross-sectional study of ageing male construction workers in Denmark

BACKGROUND

Occupational accidents continue to be a significant public health challenge worldwide. Construction workers in particular are at high risk of occupational accidents, and thus it is of major importance to identify possible predictors of occupational accidents among construction workers. We aimed to investigate the association between self-reported work pace and physical work demands and occupational accidents among ageing male construction workers in Denmark.

METHODS

Data on perceived work pace, physical work demands, and occupational accidents was acquired from questionnaires sent to ageing construction workers in Denmark in 2016 as part of the ALFA project (ALdring og Fysisk Arbejde; Ageing and Physical Work). A sample of 1270 Danish male construction workers above 50 years of age was included in the present study. Multiple logistic regression models were applied, with adjustments for age, smoking, body mass index, musculoskeletal disorders, occupation, work experience, and support at work.

RESULTS

Of 1270 construction workers, 166 (13.1%) reported an occupational accident within the last 12 months. There was no significant association between perceived work pace and occupational accidents, but physical work demands were associated with higher odds for occupational accidents, with an odds ratio of 2.27 (95% confidence interval 1.26-4.10) for medium physical work demands and 2.62 (95% confidence interval 1.50-4.57) for high physical work demands.

CONCLUSIONS

Ageing male construction workers with high physical work demands had statistically significant higher odds of having an occupational accident. By contrast, perceived work pace was not associated with occupational accidents in this large cross-sectional study.

Psychosocial factors at work from the job strain model and preventable mortality in France: The STRESSJEM prospective study

The study aimed to explore the prospective associations between psychosocial factors at work from the job strain model and preventable mortality, including smoking- and alcohol-related mortality as well as external causes of death. The study was based on prospective data and relied on a sample of 1,511,456 individuals for which data on job history, mortality and causes of death were linked over the 1976-2002 period. Exposures were the factors from the job strain model imputed through a job-exposure matrix. Various time-varying measures of exposure were used including current exposure and two measures of cumulative exposure. Preventable mortality was defined using the OECD/Eurostat list of preventable causes of death. The associations between exposures and outcomes were studied using Cox proportional hazards models. Effect modification by gender was also assessed. Over the study period, 57,264 preventable deaths occurred before the age of 75 years. Low decision latitude, low social support, job strain, iso-strain, passive job, and high strain were associated with preventable mortality, and associations of stronger magnitude were found for job strain and isostrain among men. Stronger associations were observed for alcohol-related mortality than for smoking-related mortality and external causes of death. The fractions of preventable mortality attributable to current exposure to job strain and isostrain were significant among men only (5.1% and 3.3%). Psychosocial factors at work from the job strain model may play a role on preventable mortality. Intensifying research and prevention towards the psychosocial work environment may be helpful to reduce risky health-related behaviours and related mortality.

Effect of Joint Exposure to Psychosocial and Physical Work Factors on the Incidence of Workplace Injuries: Results From a Longitudinal Survey

OBJECTIVE

To analyze the interaction between physical and psychosocial work factors regarding the workplace injuries incidence among 6900 workers out of a longitudinal survey.

METHODS

Based on responses to questionnaires, we obtained exposure groups respectively for physical factors and for psychosocial factors using hierarchical clustering. We performed multiple Poisson regression model with the workplace injuries incidence during 4 years of follow-up as the outcome and the clusters as the independent variables of interest.

RESULTS

High psychosocial exposure had a deleterious effect on workplace injuries incidence, which was no longer significant when adjusting for physical factors. The difference in model-based workplace injuries rates between high and low psychosocial exposures seemed to increase (non-significantly) with increasing physical exposure.

CONCLUSIONS

The risk of workplace injuries was highest among workers with high physical exposures regardless of the psychosocial exposures.

Examining Organizational, Cultural, and Individual-Level Factors Related to Workplace Safety and Health: A Systematic Review and Metric Analysis

One major gap in existing health communication research is that few studies have synthesized findings from the literature to map out what are the key factors related to workplace (a) safety awareness, (b) safety risks, (c) health awareness, and (d) health risks. This study bridges the gap by systematically reviewing what these organizational, cultural, and individual-level factors are, and examine the impact of workplace safety and health publications using traditional and alternative metrics in academic and non-academic settings. Through an iterative process of coding, the results revealed six categories of organizational (management commitment, management support, organizational safety communication, safety management systems, physical work environment, and organizational environment), two cultural (interpersonal support and organizational culture), and four individual-level (perception, motivation, attitude, and behavior) factors. In terms of impact, articles that were most impactful in academia (e.g., high citation count) may not necessarily receive the same amount of online attention from the public. Theoretical and practical implications for health communication were discussed.

Impact of Workplace Conflicts on Self-Reported Medically Certified Sickness Absence in Latvia

Sickness absence is one of the most important working population health indicators. It is a complex phenomenon that is investigated by health care and occupational health specialists, economists, and work psychologists. Sickness absence is used as a predictor for morbidity and mortality, but besides the health status of an individual, sickness absence is influenced by demographic, socio-economic factors, and work environment factors. Conflicts at work are a common psychosocial risk factor that can affect sickness absence. The aim of the study was to investigate the association between different types of workplace conflict and self-reported medically certified sickness absence using cross-sectional survey data pooled from four periodic national surveys—Work conditions and risks in Latvia (2006–2018). The sample is representative of the working population of Latvia, as respondents were randomly drawn from different regions and industries. In total, the study sample (n = 8557) consisted of employees between 16 and 80 years old (average 42.8 +/− 12.6) of which 46.2% were males and 53.8% were females. Researchers used the computer-assisted personal interviewing (CAPI) method for collecting data. The association between workplace conflicts and sickness absence was analysed by using binomial logistic regression and calculated as odds ratios (OR) with 95% confidence intervals (CI), with adjustment for gender, age, education and survey year. The risk of sickness absence was higher among women (OR = 1.24, CI 1.13–1.35), employees aged 25–44 years old and employees with higher income. Controlling for socio-demographic factors and survey year, the odds of sickness absence increased significantly for all types of workplace conflict analysed. The strongest association with sickness absence was related to conflicts between managers and employees (OR = 1.51, CI 1.37–1.66) and conflicts between groups of employees (OR = 1.45, CI 1.31–1.61). Conflicts between employees and with customers also increased the odds of sickness absence (OR = 1.39, CI 1.27–1.52 and OR = 1.11, CI 1.01–1.23, respectively). Our findings suggest that tailored interventions at a company level for reducing workplace conflicts as risk factors of sickness absence are required. Those should focus on the improvement of managers’ leadership and human resource management skills.

Psychosocial Work Factors of the Job Strain Model and All-Cause Mortality: The STRESSJEM Prospective Cohort Study

OBJECTIVE

The objectives were to examine the prospective associations between psychosocial work factors of the job strain model and all-cause mortality in a national representative cohort of French employees using various measures of time-varying exposure.

METHODS

The study was based on a sample of 798,547 men and 697,785 women for which data on job history from 1976 to 2002 were linked to mortality data from the national death registry. Psychosocial work factors from the validated job strain model questionnaire were imputed using a job-exposure matrix. Three time-varying measures of exposure were explored: current, cumulative, and recency-weighted cumulative exposure. Cox proportional hazards models were performed to study the associations between psychosocial work factors and mortality.

RESULTS

Within the 1976-2002 period, 88,521 deaths occurred among men and 28,921 among women. Low decision latitude, low social support, job strain, isostrain, high strain, and passive job were found to be risk factors for mortality. The model using current exposure was the best relative-quality model. The associations of current exposure to job strain and mortality were found to have hazard ratios of 1.30 (95% confidence interval [CI] = 1.24-1.36) among men and 1.15 (95% CI = 1.06-1.25) among women. The population fractions of mortality attributable to job strain were 5.64% (95% CI = 4.56%-6.71%) among men and 4.13% (95% CI = 1.69%-6.71%) among women.

CONCLUSIONS

This study supports the role of the psychosocial work factors of the job strain model on all-cause mortality. Preventive intervention to improve the psychosocial work environment may help to prevent mortality in working populations.

Salaried Workers' Self-Perceived Health and Psychosocial Risk in Guayaquil, Ecuador

Self-perceived health is an important indicator of occupational health. This research explored the relationship between poor self-perceived health and exposure to psychosocial risk factors, taking into account potential socio-demographic, occupational, and employment determinants. Using data from the First Survey of Occupational Safety and Health Conditions, covering 1049 salaried workers in Guayaquil, Ecuador, descriptive and stratified binary logistic regression analyses (odds ratios with corresponding 95% confidence intervals) were carried out. A significant relationship was found between exposure to psychosocial risk factors and the probability of presenting poor self-perceived health by socio-demographic, occupational, and employment characteristics. Occupational exposure factors to psychosocial risks were predictors of self-perceived ill health and were related to the variables analyzed; the most frequently expressed factors among the respondents were cognitive demands (DCOG) and job insecurity (IL). The results have implications in terms of designing effective workplace interventions pursuant to ensuring the health and well-being of employees.

The Association between Shift Work and Health-Related Productivity Loss due to Either Sickness Absence or Reduced Performance at Work: A Cross-Sectional Study of Korea

Background: The purpose of the present study was to investigate the association between shift work and health-related productivity loss (HRPL) due to either sickness absence or reduced performance at work. Methods: From January 2020 to February 2020, data were collected using the web-based questionnaire. Workers in Korea (n = 4197) were selected with the convenience sampling method. To evaluate HRPL, the Korean version of the “Work Productivity and Activity Impairment Questionnaire” was used. The nonparametric association between shift work and HRPL was determined. To estimate productivity loss by shift work, generalised linear models were used, and the productivity loss of workers who did not do shift work was used as the reference. Contrasts between the reference (non-shift work) and shift work, including the shift work subtype, were demonstrated. In the adjusted model, age, gender, and occupation were included as covariates. To test whether there were differences in this association by gender, a gender-stratified analysis was conducted. Results: Shift work significantly reduced productivity (2.5% points; 95% CI: 0.2–4.6). The fixed night shift had the largest productivity loss (7.7% points; 95% CI: 1.8–13.7), and the relationship between HRPL and shift work was more prominent among female workers. Conclusions: Shift work is related to an increase in HRPL, and there are gender differences in this association. Our study further indicated that a fixed night shift is most detrimental to workers’ health and productivity.

Disparate exposure to physically demanding working conditions in France

BACKGROUND

Our study was aimed at examining disparate exposure to physically demanding working conditions in France, a key objective being to identify the types of employees/jobs requiring high-priority preventive actions.

METHODS

We analyzed the data from the 2017 French nationwide cross-sectional survey (SUMER) on occupational hazards to which French employees in various sectors were subjected. The prevalence of several types of physically demanding working conditions (lifting of heavy loads, awkward body postures, vibrations, noise, and extreme temperatures) was explored. Potential associations of individual and job characteristics with these factors of hardship at work were studied by multivariate logistic regression.

RESULTS

In total, 48% of employees were exposed to at least one physically demanding working condition and 24.8% were exposed to multiple constraints. While managers and intellectual professionals were exposed relatively infrequently to physical constraints, blue-collar workers experienced the highest frequency of exposure. On the one hand, the role of company size depended on the factor of hardship at work considered; on the other hand, employees in large-scale companies were generally less exposed. As expected, employees in the construction industry were the most exposed to physical constraints; that said, our results also show that some activities in the services sector (e.g., personal care, administrative and support services) were quite significantly affected by a wide array of physically demanding working conditions.

CONCLUSION

Notwithstanding the establishment in France of Plans de Santé au travail (preventive workplace health and safety plans), occupational risks were found to be high, and above all, they were unevenly distributed among the various socio-professional categories, and strongly contributed to social inequalities in health. Our results identify the types of publics to be designated as high-priority targets for preventive measures aimed at reducing the adverse impacts of physically demanding working conditions and the incidence of associated musculoskeletal disorders.

Workplace Violence and Long-term Sickness Absence: Assessment of the Potential Buffering Effect of Social Support in Two Occupational Cohort Studies

OBJECTIVES

We aimed to determine the effect of workplace violence on long-term sickness absence, and whether social support from supervisors and colleagues buffer this effect.

METHODS

Information on workplace violence and social support were derived from the Danish Work Environment Cohort Study in 2000, 2005, and 2010 and the Swedish Longitudinal Occupational Survey of Health in 2006 and 2008. Individual- and joint-effects on register-based long-term sickness absence were determined using logistic regression models for repeated measurements. Cohort-specific estimates were combined in random effect meta-analyses.

RESULTS

Workplace violence and low social support were independently associated with a higher risk of long-term sickness absence, and we did not find evidence of an interaction.

CONCLUSION

Exposure to workplace violence is a risk factor for long-term sickness absence while social support is associated with a lower risk of long-term sickness absence.

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.

Working conditions and depression in the French national working population: Results from the SUMER study

OBJECTIVES

The objectives were to explore the associations between various types of occupational exposures and depression in the French national working population, most of the studies in the literature focussing on a limited number of exposures and on symptom scales.

METHODS

The study was based on a nationally representative sample of 25 977 employees, 14 682 men and 11 295 women. Depression was measured using the PHQ-9 instrument and algorithm. Occupational exposures included factors related to both the psychosocial and physical work environment. Weighted logistic regression analyses were performed to study the associations between exposures and outcome with adjustment for covariates among men and women separately.

RESULTS

The prevalence of depression was higher for women than for men (5.70% versus 3.78%). The final models showed that low decision latitude, low reward, bullying, work-family and ethical conflicts for both genders, and high psychological demands, low social support, and long working hours among women were risk factors for depression. No occupational exposure of physical, biomechanical, chemical and biological nature was associated with depression. Sensitivity analyses confirmed the robustness of the results.

CONCLUSIONS

Significant associations were found between psychosocial work exposures and depression, and there were some differences in these associations between genders. This study is one of the first to provide a comprehensive overview of occupational exposures in association with depression. More prevention towards the psychosocial work environment is needed to improve mental health of working populations.

The prevalence of ill-treatment and bullying at work in Ireland

Purpose

The purpose of this paper is to examine the prevalence of ill-treatment and bullying experienced by Irish workers and to explore individual and organisational predictors. The most recent national figures available are specific to bullying and predate the economic recession; therefore, this study is timely and investigates a broader range of negative behaviours.

Design/methodology/approach

A questionnaire survey study on a national probability sample of Irish employees was conducted (N = 1,764). The study design replicated the methodology employed in the British workplace behaviour study.

Findings

The results showed that 43% of Irish workers had experienced ill-treatment at work over the past two years, with 9% meeting the criteria for experiencing workplace bullying. A number of individual and organisational factors were found to be significantly associated with the experience of ill-treatment at work.

Research limitations/implications

This study provides national-level data on workplace ill-treatment and bullying that are directly comparable to British study findings.

Practical implications

The findings indicate that a significant number of Irish workers experience ill-treatment at work, and that workplace bullying does not appear to have decreased since the last national study was conducted in Ireland.

Social implications

This study is of use to the Irish regulator and persons responsible for managing workplace bullying cases, as it identifies high-risk work situations and contributing individual factors.

Originality/value

This study provides national Irish data on workplace behaviour and ill-treatment following a severe economic recession.

Prospective associations of psychosocial work exposures with mortality in France: STRESSJEM study protocol

INTRODUCTION

Although evidence has been provided on the associations between psychosocial work exposures and morbidity outcomes in the literature, knowledge appears much more sparse on mortality outcomes. The objective of STRESSJEM is to explore the prospective associations between psychosocial work exposures and mortality outcomes among the national French working population. In this paper, we describe the study protocol, study population, data sources, method for exposure assessment, data analysis and future plans.

METHODS AND ANALYSIS

Data sources will include: the data from the national SUMER survey from DARES on the evaluation of psychosocial work exposures and the data from the COSMOP programme from Santé publique France linking job history (DADS data from INSEE) and mortality according to causes of death (data from the national death registry, INSERM-CépiDc). A sample of 1 511 456 individuals will form the studied prospective cohort for which data are available on both job history and mortality over the period 1976-2002. Psychosocial work exposures will be imputed via a job-exposure matrix using three job title variables that are available in both the SUMER and COSMOP data sets. Our objectives will be to study the associations between various psychosocial work exposures and mortality outcomes. Psychosocial work exposures will include the job strain model factors as well as other psychosocial work factors. Various measures of exposure over time will be used. All-cause and cause-specific mortality will be studied.

ETHICS AND DISSEMINATION

Both the SUMER survey and the COSMOP programme have been approved by French ethics committees. Dissemination of the study results will include a series of international peer-reviewed papers and at least one paper in French. The results will be presented in national and international conferences. This project will offer a unique opportunity to explore mortality outcomes in association with psychosocial work exposures in a large national representative sample of the working population.

Effort-Reward Imbalance and Job Strain: A Composite Indicator Approach

The Job Demand-Control-Support (JDC-S) and Effort-Reward Imbalance (ERI) models dominate psychosocial work environment research and practice, with their independent and collective contributions to employee health having been extensively demonstrated. Psychosocial risk assessment in the humanitarian aid sector is in its infancy, and there is a need to identify appropriate psychosocial work environment models to inform approaches to assessment. The aim of this study is to examine the efficacy of these models separately and in combination to identify psychological distress in humanitarian aid workers. Cross-sectional survey data were obtained from 283 humanitarian aid workers. Logistic regression analyses investigated the separate and combined ability of the models to identify psychological distress. More than half of the participant sample reported psychological distress, and one third reported high ERI and high job strain. When tested separately, each model was associated with a significantly elevated likelihood of psychological distress. When tested in combination, the two models offered a superior estimation of the likelihood of psychological distress than achieved by one model in isolation. Psychosocial risk assessment in the humanitarian aid sector encompassing the characteristics of both these leading psychosocial work environment models captures the breadth of relevant generic psychosocial work characteristics. These initial findings require corroboration through longitudinal research involving sector-representative samples.

Socioeconomic and demographic predictors of high blood pressure, diabetes, asthma and heart disease among adults engaged in various occupations: evidence from India

In India, non-communicable diseases (NCDs) accounted for nearly 62% of all deaths in 2016. Four NCDs - high blood pressure, diabetes, asthma and heart disease - together accounted for over 34% of these deaths. Using data from two rounds of the India Human Development Surveys (IHDSs), levels and changes in the prevalence rates of the four NCDs (based on diagnosed cases) among adults aged 15-69 years in India between 2004-05 and 2011-12 were examined by socioeconomic and demographic factors and for five broad occupation categories. The socioeconomic and demographic risk factors for each of these NCDs were determined using multiple linear logistic regression analysis of pooled data from two rounds of the IHDS. The results showed that while urban residence, age, female sex and education were associated with higher odds of high blood pressure, diabetes and heart disease, household economic status was associated with higher odds for all four NCDs. Furthermore, increased higher odds of high blood pressure, diabetes and heart disease were found for the legislator/senior official/professional occupation group compared with non-workers. Skilled agricultural/elementary workers had lower odds of high blood pressure, diabetes, asthma and heart disease. Craft/machine-related trade workers had higher odds of high blood pressure and diabetes, and reduced odds of asthma and heart disease. Compared with non-workers, the odds ratios for asthma were lower for all other occupational categories. During the two study decades, the Government of India implemented several programmes designed to improve the health and well-being of its people. However, more focused attention on the adult population is needed, and special attention should be paid to the issue of the occupational health of the working population through the strict implementation of work place safety protocols and the removal of potential health hazards.

Working conditions and risk exposure of employees whose occupations require driving on public roads - Factorial analysis and classification

INTRODUCTION

Several studies of the working conditions of drivers, and in particular on their pace of work, have enabled a better understanding of the risk factors for road accidents that occur during work. However, few studies are available on the risk exposure and working conditions of employees whose occupations involve driving. The purpose of this paper is to identify the different groups of employees occupationally exposed to road risk and to classify them according to working conditions.

METHODOLOGY

A Multiple Correspondence Analysis (MCA) was implemented on the 41,727 individuals from the SUMER 2010 survey (Medical Monitoring of Occupational Risk Exposure: SUrveillance Médicale des Expositions aux Risques professionnels) and for 45 variables about working conditions. The analysis used 5 categories of weekly driving exposure as a supplementary variable (variable which is not used to perform the MCA): Non-exposure; Exposed <2 h; Exposed 2-10 hours; Exposed 10-20 hours; and Exposed >20 h. The results of the MCA were used to construct an ascending hierarchical classification.

RESULTS

The first factorial axis differentiates between conventional and unconventional work schedules. Axis 2 differentiates modalities corresponding to the working hours of the most recent working week. The third axis chiefly contrasts persons who have rules to follow with those who have none. An ascending hierarchical classification distinguishes 10 clusters of individuals according to working conditions. Four clusters of employees were excessively exposed to occupational driving. Clusters also have distinct demographic, occupational and psychosocial characteristics.

CONCLUSION

Analysis of data from the SUMER survey confirms that employees exposed to road risk are particularly affected by atypical work time characteristics, but can be found in all activity sectors and in all types of job.

Development and Validation of an Interdisciplinary Worker's Health Approach Instrument (IWHAI)

The present study aimed to develop and validate an Interdisciplinary Worker's Health Approach Instrument (IWHAI). The development stage comprised a group of 10 professionals, including physicians, nurses, nutritionists, dentists and physical educators, as well as a judges' committee, composed by 19 recognized experts in the area of worker's health (WH). For the validation of the IWHAI, the Spearman's correlation coefficient (rs) was calculated, the factor analysis to the instrument was applied, and the Cronbach's alpha (α) and the Intraclass correlation coefficient (ICC) were calculated. The IWHAI was structured in five dimensions, integrating 43 health indicators, on a scale of 0-4, totalling 215 sub-indices with closed response coding. The instrument was validated with a Kappa coefficient (KAPPA) (k), with excellent agreement for all attributes, i.e., k = 0.88 for applicability, k = 0.80 for clarity and k = 0.82 for relevance. p > 0.05 results reveal moderate to strong positive correlations between some variables, i.e., pests, vectors and air quality/drinking water quality (rs = 0.69). A total of 14 components of the factor analysis, explaining 62.6% of the data variance, were extracted. α value is considered moderate to high, α = 0.61, the ICC value also being considered moderate to high, with ICC = 0.61. The IWHAI is considered validated, constituting a technological innovation for an interdisciplinary approach in the field of WH, enabling the prevention and integral promotion of health.

Can a poor psychosocial work environment and insufficient organizational resources explain the higher risk of ill-health and sickness absence in human service occupations? Evidence from a Swedish national cohort

AIM

The aim of this study was to investigate differences in burnout, self-rated health (SRH) and sickness absence between human service occupations (HSOs) and other occupations, and whether they can be attributed to differences in psychosocial work environment and organizational resources.

METHODS

Data were derived from the Swedish Longitudinal Occupational Survey of Health, an approximately representative sample of the Swedish working population ( n = 4408). Employment in HSOs, psychosocial work environment and organizational resources in 2012 predicted relative risks of sickness absence, burnout and suboptimal SRH in 2014 using modified Poisson regressions. The psychosocial work factors' and organizational resource variables' relative importance were estimated by adding them to the models one by one, and with population attributable fractions (PAFs).

RESULTS

Employment in HSOs was associated with a higher risk of sickness absence and the risk was explained by psychosocial and organizational factors, particularly high emotional demands, low work-time control and exposure to workplace violence. Employment in HSOs was not associated with burnout after sociodemographic factors were adjusted for, and furthermore not with SRH. A lower risk of suboptimal SRH was found in HSOs than in other occupations with equivalent psychosocial work environment and organizational resources. PAFs indicated that psychosocial work environment and organizational resource improvements could lead to morbidity reductions for all outcomes; emotional demands were more important in HSOs.

CONCLUSIONS

HSOs had higher risks of sickness absence and burnout than other occupations. The most important work factors to address were high emotional demands, low work-time control, and exposure to workplace violence.

Occupational factors associated with major depressive disorder: A Brazilian population-based study

BACKGROUND

There have been very few studies exploring the occupational risk factors for major depressive disorder (MDD) in the working populations in Latin America. The aim of this study was to explore the associations between a large set of occupational factors and MDD in the Brazilian working population.

METHODS

The study was based on the cross-sectional data from the Brazilian National Health Survey, 2013. 60,202 people were interviewed (response rate: 91.9%). Among them, 36,442 were working, 19,450 men and 16,992 women. MDD was measured using the diagnostic algorithm (DSM-IV criteria) of the PHQ-9. Occupational factors included job characteristics, working time factors, psychosocial work stressors and physico-chemical exposures. Logistic regression models were performed and adjusted for sociodemographic factors. All analyses were conducted using weighted and stratified data by gender.

RESULTS

The following occupational factors were associated with a higher risk of MDD: working part time (≤20 h a week) and stress at work for both genders, workplace violence, intense physical activity, exposure to noise and chemicals among women, and prolonged exposure to sun among men. Associations of stress and violence at work with MDD were particularly strong.

LIMITATIONS

Cross-sectional study design, healthy worker effect and reporting bias may have impacted the results.

CONCLUSIONS

This study, one of the first studies among the Brazilian working population, showed that psychosocial work stressors were the strongest risk factors for MDD. Physico-chemical exposures deserve more attention in association with MDD. Prevention policies oriented toward the work environment may help to prevent depression at the workplace.

Psychosocial risks in small enterprises: the mediating role of perceived working conditions in the relationship between enterprise size and workers' anxious or depressive episodes

Purpose. The relationship between enterprise size and psychosocial working conditions has received little attention so far but some findings suggest that conditions are more favorable in small enterprises. This could have a positive impact on workers' mental health. The objective of this study was to test the mediating effect of perceived working conditions in the relationship between enterprise size and anxious or depressive episodes. Methods. Data from the 2010 SUMER - Surveillance Médicale des Expositions aux Risques professionnels (French periodical cross-sectional survey) were analyzed; N = 31,420 for the present study. Anxious or depressive episodes were measured with the hospital anxiety and depression scale and the perceived working conditions were psychological demand, decision latitude and social support as assessed with Karasek's job content questionnaire. The indirect effect was tested according to the method proposed by Preacher and Hayes. Results. In a multivariate logistic regression, the risk of anxious or depressive episodes was found to be lower in micro enterprises (2-9 employees). Formal tests pointed to a significant indirect effect of enterprise size on mental health through perceived working conditions, with a larger effect for psychological demand. Conclusion. This study highlights perceived working conditions as an explanation of the effects of enterprise size.

Working conditions in the explanation of occupational inequalities in sickness absence in the French SUMER study

Background

Explanations of social inequalities in sickness absence are lacking in the literature. Our objectives were to evaluate the contribution of various occupational exposures in explaining these inequalities in a national representative sample of employees.

Methods

The study was based on the cross-sectional sample of the SUMER 2010 survey that included 46 962 employees, 26 883 men and 20 079 women. Both sickness absence spells and days within the last 12 months, as health indicators, were studied. Occupation was used as a marker of social position. The study included both psychosocial work factors (variables related to the classical job strain model, psychological demands, decision latitude, social support and understudied variables related to reward, job insecurity, job promotion, esteem, working time/hours and workplace violence) and occupational exposures of chemical, biological, physical and biomechanical nature. Weighted age-adjusted Poisson and negative binomial regression analyses were performed.

Results

Strong occupational differences were found for sickness absence spells and days and for exposure to most work factors. Psychosocial work factors contributed to explain occupational differences in sickness absence spells, and the contributing factors were: decision latitude, social support, reward, shift work and workplace violence. Physical exposure, particularly noise, and biomechanical exposure were also found to be contributing factors. Almost no work factor was found to contribute to occupational differences in sickness absence days.

Conclusion

Preventive measures at the workplace oriented towards low-skilled occupational groups and both psychosocial work factors and other occupational exposures may be beneficial to reduce sickness absence spells and occupational differences in this outcome.

Role of working conditions in the explanation of occupational inequalities in work injury: findings from the national French SUMER survey

Background

Social inequalities in work injury have been observed but explanations are still missing. The objectives of this study were to evaluate the contribution of working conditions in the explanation of social inequalities in work injury in a national representative sample of employees.

Methods

The study was based on the cross-sectional sample of the national French survey SUMER 2010 including 46,962 employees, 26,883 men and 20,079 women. The number of work injuries within the last 12 months was studied as the outcome. Occupation was used as a marker of social position. Psychosocial work factors included various variables related to the classical job strain model, psychological demands, decision latitude, social support, and other understudied variables related to reward, job insecurity, job promotion, esteem, working time and hours and workplace violence. Occupational exposures of chemical, biological, physical and biomechanical nature were also studied. Weighted age-adjusted Poisson regression analyses were performed.

Results

Occupational gradients were observed in the exposure of most psychosocial work factors and occupational exposures. Strong occupational differences in work injury were found, blue-collar workers being more likely to have work injury. Chemical, biological, physical and biomechanical exposures contributed to explain the occupational differences in work injury substantially. Noise, thermic constraints, manual materials handling, postural/articular constraints and vibrations had significant contributions. Psychosocial work factors also contributed to explain the differences especially among women.

Conclusion

Prevention policies oriented toward chemical, biological, physical, biomechanical and psychosocial work exposures may contribute to reduce the magnitude of occupational differences in work injury.

Study of the validity of a job-exposure matrix for the job strain model factors: an update and a study of changes over time

OBJECTIVES

The objectives of the study were to construct a job-exposure matrix (JEM) for psychosocial work factors of the job strain model, to evaluate its validity, and to compare the results over time.

METHODS

The study was based on national representative data of the French working population with samples of 46,962 employees (2010 SUMER survey) and 24,486 employees (2003 SUMER survey). Psychosocial work factors included the job strain model factors (Job Content Questionnaire): psychological demands, decision latitude, social support, job strain and iso-strain. Job title was defined by three variables: occupation and economic activity coded using standard classifications, and company size. A JEM was constructed using a segmentation method (Classification and Regression Tree-CART) and cross-validation.

RESULTS

The best quality JEM was found using occupation and company size for social support. For decision latitude and psychological demands, there was not much difference using occupation and company size with or without economic activity. The validity of the JEM estimates was higher for decision latitude, job strain and iso-strain, and lower for social support and psychological demands. Differential changes over time were observed for psychosocial work factors according to occupation, economic activity and company size.

CONCLUSIONS

This study demonstrated that company size in addition to occupation may improve the validity of JEMs for psychosocial work factors. These matrices may be time-dependent and may need to be updated over time. More research is needed to assess the validity of JEMs given that these matrices may be able to provide exposure assessments to study a range of health outcomes.

Linking Workplace Aggression to Employee Well-Being and Work: The Moderating Role of Family-Supportive Supervisor Behaviors (FSSB)

PURPOSE

The present study examined the moderating effects of family-supportive supervisor behaviors (FSSB) on the relationship between two types of workplace aggression (i.e., patient-initiated physical aggression and coworker-initiated psychological aggression) and employee well-being and work outcomes.

METHODOLOGY

Data were obtained from a field sample of 417 healthcare workers in two psychiatric hospitals. Hypotheses were tested using moderated multiple regression analyses.

FINDINGS

Psychiatric care providers' perceptions of FSSB moderated the relationship between patient-initiated physical aggression and physical symptoms, exhaustion and cynicism. In addition, FSSB moderated the relationship between coworker-initiated psychological aggression and physical symptoms and turnover intentions.

IMPLICATIONS

Based on our findings, family-supportive supervision is a plausible boundary condition for the relationship between workplace aggression and well-being and work outcomes. This study suggests that, in addition to directly addressing aggression prevention and reduction, family-supportive supervision is a trainable resource that healthcare organizations should facilitate to improve employee work and well-being in settings with high workplace aggression.

ORIGINALITY

This is the first study to examine the role of FSSB in influencing the relationship between two forms of workplace aggression: patient-initiated physical and coworker- initiated psychological aggression and employee outcomes.

Do Personal Factors or Types of Physical Tasks Predict Workplace Injury?

Occupational health research has shown that certain worker and job characteristics are risk factors for workplace injuries. Workers who engage in physically demanding jobs, especially those jobs that involve repetitive motion, are at greater risk for work-related musculoskeletal disorders (WMSD). These risks are particularly prevalent in the health care sector. It is often reported that nurses are at higher risk of workplace musculoskeletal injury than other health care workers due to frequent lifting and transfer of patients and the prevalence of workplace violence. However, many analyses of the physical requirements of jobs do not consider the modifying effect of time spent on a physical task and the risk of WMSD. This study compared the risks of WMSD among workers in health care facilities based on the type of physical tasks and amount of time workers spent on such tasks. Workers who worked longer on a physical task reported more WMSD than those who spent less time on the same physical task. The risk of WMSD was twice as high (odds ratio [OR] = 2.3) among workers who sit less than 2 hours each day compared with those who sit longer. This study found that physical tasks associated with health care jobs and the amount of time spent on these tasks constitutes serious risk factors for WMSD.

Cumulative exposure to shift work and sickness absence: associations in a five-year historic cohort

BACKGROUND

Exposure to shift work has been associated with negative health consequences, although the association between shift work and sickness absence remains unclear. The aim of this study is to investigate associations between cumulative exposure to shift work and sickness absence among ground staff employees of an airline company.

METHODS

This study used data from the MORE (Monitoring Occupational Health Risks in Employees) cohort, which is a 5-year historic cohort. The population of the present study consisted of 7562 ground staff employees. For each employee, work schedules and sickness absence days between 2005 and 2009 were obtained from company records. For the exposure to different shift schedule types and to the cumulative number of night shifts, the association with long-term sickness absence (>7 consecutive sickness absence days) and the number of sickness absence episodes during 2009, was calculated using logistic and Poisson regression analyses. Socio-demographic variables, work-related variables, job classification variables, and previous sickness absence days were regarded as confounders.

RESULTS

After adjusting for previous sickness absence and job classification variables, only the group of employees that switched into working in a three-shift schedule, showed a significantly increased risk for long-term sickness absence (OR = 1.31, 95%CI 1.02-1.69). Night shift exposure was not significantly associated with long-term sickness absence. Exposure to shift work was negatively associated with more sickness absence episodes. Employees who were exposed to more than 46 night shifts also showed a lower risk for more sickness absence episodes. Subgroup analyses showed that single employees and employees without children had an increased risk for long-term sickness absence when exposed to a three-shift schedule, and when they had changed between shift schedule types.

CONCLUSIONS

Cumulative exposure to shift work proved to be negatively associated with more sickness absence episodes, and was not associated with more long-term sickness absence, although selection bias could not be ruled out. Future research should explore the influence of household composition, and take into account both previous sickness absence and psychosocial and physical work factors to obtain a better estimation of the association between shift work and sickness absence.

Stressful work characteristics, health indicators and work behavior: the case of machine operators

This article shows the results of research on psychosocial risks for a group of machine and plant operators (n = 1014) from the construction, chemical, energy, mining, metal and food industries in Poland. The Psychosocial Risk Scale designed in Nofer Institute of Occupational Medicine (NIOM) by Moscicka-Teske and Potocka was used to indicate the occurrence of general and specific occupational stressors and the level of their stressfulness. The results revealed that the studied machine and plant operators experience job context stress - related to working environment features concerning work organization - more frequently than job content stressors - related to the type of tasks they perform. Moreover, a correlation analysis between work features and the health and occupational functioning of the respondents revealed significant but weak relationships between the variables (from -0.08 to -0.23). Comparative analysis revealed the differences between the studied sectors. Such a comparison makes it possible to set goals for each sector and to attempt to improve the distinctive areas.

The Relocation of a Health Care Department's Impact on Staff: A Cross-Sectional Survey

OBJECTIVE

This survey compares certain quality of work-life factors between a relocated work group and a control group.

METHODS

A self-administered, cross-sectional survey was conducted 12 months after five departments (304 workers) had been relocated between two public health sites. The survey explored the workers' psychosocial job characteristics, their perceived health, and psycho-organizational constraints. The results compared both the relocated and control groups by using univariate and then multivariate statistical analyzes.

RESULTS

When compared with the control group (n = 272), the relocated group (n = 180) showed a higher prevalence of psychosocial job characteristic "isostrain." The relocated group showed greater psycho-organizational constraints regarding the organizations favoring communication and team relationships.

CONCLUSIONS

It seems that staff relocation can provoke a sense of uncertainty and isolation. Perhaps better communication might have reduced this and deter possible negative health outcomes.

Validity of a Job-Exposure Matrix for Psychosocial Job Stressors: Results from the Household Income and Labour Dynamics in Australia Survey

Introduction

A Job Exposure Matrix (JEM) for psychosocial job stressors allows assessment of these exposures at a population level. JEMs are particularly useful in situations when information on psychosocial job stressors were not collected individually and can help eliminate the biases that may be present in individual self-report accounts. This research paper describes the development of a JEM in the Australian context.

Methods

The Household Income Labour Dynamics in Australia (HILDA) survey was used to construct a JEM for job control, job demands and complexity, job insecurity, and fairness of pay. Population median values of these variables for all employed people (n = 20,428) were used to define individual exposures across the period 2001 to 2012. The JEM was calculated for the Australian and New Zealand Standard Classification of Occupations (ANZSCO) at the four-digit level, which represents 358 occupations. Both continuous and binary exposures to job stressors were calculated at the 4-digit level. We assessed concordance between the JEM-assigned and individually-reported exposures using the Kappa statistic, sensitivity and specificity assessments. We conducted regression analysis using mental health as an outcome measure.

Results

Kappa statistics indicate good agreement between individually-reported and JEM-assigned dichotomous measures for job demands and control, and moderate agreement for job insecurity and fairness of pay. Job control, job demands and security had the highest sensitivity, while specificity was relatively high for the four exposures. Regression analysis shows that most individually reported and JEM measures were significantly associated with mental health, and individually-reported exposures produced much stronger effects on mental health than the JEM-assigned exposures.

Discussion

These JEM-based estimates of stressors exposure provide a conservative proxy for individual-level data, and can be applied to a range of health and organisational outcomes.

Working conditions and occupational risk exposure in employees driving for work

INTRODUCTION

An analysis of the occupational constraints and exposures to which employees facing road risk at work are subject was performed, with comparison versus non-exposed employees. Objective was to improve knowledge of the characteristics of workers exposed to road risk in France and of the concomitant occupational constraints. The descriptive study was based on data from the 2010 SUMER survey (Medical Monitoring of Occupational Risk Exposure: Surveillance Médicale des Expositions aux Risques professionnels), which included data not only on road risk exposure at work but also on a range of socio-occupational factors and working conditions.

MATERIALS AND METHODS

The main variable of interest was "driving (car, truck, bus, coach, etc.) on public thoroughfares" for work (during the last week of work). This was a dichotomous "Yes/No" variable, distinguishing employees who drove for work; it also comprised 4-step weekly exposure duration: <2h, 2-10h, 10-20h and ≥20h.

RESULTS

75% of the employees with driving exposure were male. Certain socio-occupational categories were found significantly more frequently: professional drivers (INSEE occupations and socio-occupational categories (PCS) 64), skilled workers (PCS 61), intermediate professions and teaching, health, civil service (functionaries) and assimilated (PCS 46) and company executives (PCS 36). Employees with driving exposure more often worked in small businesses or establishments. Constraints in terms of schedule and work-time were more frequent in employees with driving exposure. Constraints in terms of work rhythm were more frequent in non-exposed employees, with the exception of external demands requiring immediate response. On the Karasek's Job Demand-Control Model, employees with driving exposure less often had low decision latitude. Prevalence of job-strain was also lower, as was prevalence of "iso-strain" (combination of job-strain and social isolation). Employees with driving exposure were less often concerned by hostile behavior and, when they did report such psychological violence (inspired on the Leymann questionnaire), it was significantly more frequently due to clients, users or patients.

DISCUSSION

Employees with driving exposure at work showed several specificities. The present study, based on a representative nationwide survey of employees, confirmed the existence of differences in working conditions between employees with and without driving exposure at work. In employees with driving exposure, constraints in terms of work-time and rhythm increased with weekly exposure duration, as did tension at work and exposure to hostile behavior.

Psychosocial factors at work and occupational injury: results from the French national SUMER survey

OBJECTIVE

This study aims at exploring the associations between psychosocial work factors and occupational injury.

METHODS

The study was based on 46,962 employees of the French national representative survey SUMER 2010. The associations between psychosocial work factors and occupational injury/absence duration for injury within the last year were studied using weighted logistic and negative binomial regression models adjusted for covariates.

RESULTS

Verbal abuse and low predictability for both sexes, psychological demands for women and low reward, physical violence, and bullying for men were associated with occupational injury. Low decision latitude and psychological demands for women were associated with absence duration for injury.

CONCLUSIONS

Some psychosocial work factors may play a role in occurrences of occupational injury, but the role is unclear in relation to absence duration for injury.

Workplace Violence: A Survey of Nationally Registered Emergency Medical Services Professionals

Previous studies on violence against prehospital personnel have mainly reported on “verbal” and “physical” violence. This study explored how provider demographic and work-related characteristics were associated with five different forms of workplace violence (being cursed or threatened; being punched, slapped, or scratched; being spat upon; being stabbed/stabbing attempt; and being shot/shooting attempt). A cohort of nationally registered United States Emergency Medical Services professionals was surveyed to determine the experience of each of these types of patient initiated violence by these providers and their partners. Multivariable logistic regression analyses indicated gender was significantly associated with both being cursed/threatened and being stabbed or experiencing a stabbing attempt (odds ratio (OR) = 0.65, CI = 0.44–0.96; OR = 0.27, CI = 0.09–0.75, resp.). Level of EMT practice was significantly associated with being cursed/threatened, being spat upon, and being punched, slapped, or scratched (OR = 0.17, CI = 0.11–0.27; OR = 0.30, CI = 0.21–0.43; OR = 0.31, CI = 0.22–0.44, resp.). Both community size and experience were significantly associated with all the types of violence investigated. EMS workplace violence research is at its infancy; thus this study adds to a limited but growing body of knowledge.

Development of a mobbing short scale in the Gutenberg Health Study

PURPOSE

Despite its highly detrimental potential, most standard questionnaires assessing psychosocial stress at work do not include mobbing as a risk factor. In the German standard version of COPSOQ, mobbing is assessed with a single item. In the Gutenberg Health Study, this version was used together with a newly developed short scale based on the Leymann Inventory of Psychological Terror. The purpose of the present study was to evaluate the psychometric properties of these two measures, to compare them and to test their differential impact on relevant outcome parameters.

METHODS

This analysis is based on a population-based sample of 1441 employees participating in the Gutenberg Health Study. Exploratory and confirmatory factor analyses and reliability analyses were used to assess the mobbing scale. To determine their predictive validities, multiple linear regression analyses with six outcome parameters and log-binomial regression models for two of the outcome aspects were run.

RESULTS

Factor analyses of the five-item scale confirmed a one-factor solution, reliability was α = 0.65. Both the single-item and the five-item scales were associated with all six outcome scales. Effect sizes were similar for both mobbing measures.

CONCLUSION

Mobbing is an important risk factor for health-related outcomes. For the purpose of psychosocial risk assessment in the workplace, both the single-item and the five-item constructs were psychometrically appropriate. Associations with outcomes were about equivalent. However, the single item has the advantage of parsimony, whereas the five-item construct depicts several distinct forms of mobbing.

Psychosocial factors at work and occupational injuries: A prospective study of the general working population in Norway

BACKGROUND

We examined the effects of psychosocial stressors at work on subsequent injuries, taking into account organizational and mechanical working conditions.

METHODS

Randomly drawn from the general population, the cohort comprised respondents with an active employee relationship in 2006 and 2009 (n = 6,745).

OUTCOME MEASURE

"Have you, over the past 12 months, afflicted injuries that were caused by an accident at work, and resulting in time off work after the day of the accident?".

RESULTS

High job strain (Odds ratio [OR] 2.31; 95% confidence interval [CI] 1.16-4.57), high role conflict (OR 3.01; 95% CI 1.70-5.31), and high emotional demands (OR 1.96; 95% CI 1.15-3.35) predicted injury at follow up (P < 0.01). The population risk attributable to each of these factors ranged from 11% to 14%.

CONCLUSIONS

Excess risk of occupational injuries was attributable to job strain, role conflict, and emotional demands. These factors are potentially amenable to preventive measures.
