Organizational change and employee mental health
A prospective multilevel study of the associations between organizational changes and clinically relevant mental distress Objective: The goal of this paper was to elucidate the relationship between exposure to separate, multiple or repeated organizational change at both individual- and work-unit level and subsequent clinically relevant mental distress amongst employees two years after change had taken place. Methods: A full panel, prospective design was utilized. Data were collected at two time-points two years apart, by self-administered, online questionnaires. Organizational change was measured...
Long-term occupational trajectories and suicide
A 22-year follow-up of the GAZEL cohort study Objective: Most suicides occur among individuals of working age. Risk is elevated in some occupational groups, however relations between long-term occupational trajectories and suicide are not well known. We describe career-long occupational trajectories and examine their influence on suicide. Methods: Data come from GAZEL, a French cohort study set among employees of a large national utilities company. Occupational grade was obtained from company records from the time of hiring (1953?1988). Groupbased trajectory models were used to define occupational...

Bi-directional relation between effort-reward imbalance and risk of neck-shoulder pain
Assessment of mediation through depressive symptoms using occupational longitudinal data Objectives: Bi-directional associations between perceived effort?reward imbalance (ERI) at work and neckshoulder pain have been reported. There is also evidence of associations between ERI and depressive symptoms, and between depressive symptoms and pain while the links between ERI, depressive symptoms and pain have not been tested. We aimed to assess whether depressive symptoms mediate the association between ERI and neck-shoulder pain, as well as the association between neck-shoulder pain and ERI. Methods...
Burnout in the workplace: A review of data and policy responses in the EU
This report looks at the extent of burnout experienced by workers in the EU, based on national research. As a starting point, the report sets out to consider whether burnout is viewed as a medical or occupational disease. It then examines the work determinants associated with burnout and looks at the effects of burnout, including psychosocial and physical work factors, work intensity and work organisation. It also reviews national strategies and policies regarding this issue, the involvement of the social partners in the current debate, as well as preventive actions currently in place. Source:...
Impact of shift work on the diurnal cortisol rhythm
A one-year longitudinal study in junior physicians Background: Cumulative epidemiological evidence suggests that shift work exerts harmful effects on human health. However, the physiological mechanisms are not well understood. This study aimed to examine the impact of shift work on the dysregulation of the hypothalamic-pituitary-adrenal axis, i.e. diurnal cortisol rhythm. Methods: Seventy physicians with a mean age 30 years participated in this one-year longitudinal study. Working schedules, either shift work or regular schedules with day shift, were assessed at baseline. Salivary cortisol samples...
Effects of office workstation type on physical activity and stress
Objective: Office environments have been causally linked to workplace-related illnesses and stress, yet little is known about how office workstation type is linked to objective metrics of physical activity and stress. We aimed to explore these associations among office workers in US federal office buildings. Methods: We conducted a wearable, sensor-based, observational study of 231 workers in four office buildings. Outcome variables included workers' physiological stress response, physical activity and perceived stress. Relationships between office workstation type and these variables were...
Job strain, long work hours, and suicidal ideation in US workers
A longitudinal study Purpose: To investigate whether chronic psychosocial work stressors (low job control, high job demands, job strain, low supervisor and coworker support, job insecurity, and long work hours) are longitudinally associated with suicidal ideation in a working population. Methods: Five-hundred seventy-eight workers (aged 34–69) were chosen for this analysis from those who participated in both project 1 (2004–2006 at baseline) and project 4 (2004–2009 at follow-up) of the Midlife Development in the United States II study. The median time interval between the two...
Has the Economic Crisis Worsened the Work-Related Stress and Mental Health of Temporary Workers in Spain?
This paper analyses the causal effects of temporary employment on work-related stress and mental health before (2006/07) and during the economic crisis (2011/12) and examines whether the economic recession worsened these two health outcomes. To control for selection bias, propensity scores (PS) are computed separately for men and women using microdata from two cross-sectional surveys, considering temporary (treatment group) versus permanent employment (control group). Next, we use difference-in-differences estimators stratifying by age, education level, and regional unemployment differences using...
Do Working Hours Affect Health? Evidence from Statutory Workweek Regulations in Germany
This study estimates the causal effect of working hours on health. We deal with the endogeneity of working hours through instrumental variables techniques. In particular, we exploit exogenous variation in working hours from statutory workweek regulations in the German public sector as an instrumental variable. Using panel data, we run two-stage least squares regressions controlling for individual-specific unobserved heterogeneity. We find adverse consequences of increasing working hours on subjective and several objective health measures. The effects are mainly driven by women and parents of minor...
Association between demand–control model components and blood pressure in the ELSA-Brasil study
Exploring heterogeneity using quantile regression analyses This study from Brazil provides new knowledge about the association between job strain and blood pressure (BP). The innovative analytical strategy, which combined independent assessment of the demand-control model components with gamma and quantile regression analyses, showed that BP associates differently with skill discretion and decision authority and that these associations are heterogeneous over the BP distribution and by use of antihypertensives.

Comparison of hemodynamic responses between normotensive and untreated hypertensive men under simulated long working hours
This study examined hemodynamic responses of normotensive and hypertensive participants under the simulated long working hours in an experimental laboratory. The findings showed that long working hours increases the blood pressure of individuals especially those with hypertension; suggesting that such individuals may suffer more severe damage related to long working hours.

Objectives: The aim of this study was to examine blood concentrations of 25-hydroxyvitamin D (25OHD) and parathyroid hormone (PTH) among indoor, outdoor, permanent and rotating night workers and the association with hours spent outdoors on and off work days. Methods: Blood samples were collected from 425 workers (162 indoor, 112 outdoor, 118 rotating night and 33 permanent night workers) throughout all seasons. Serum concentrations of 25-hydroxyvitamin D (25OHD) and parathyroid hormone (PTH) were analyzed by isotope dilution liquid chromatography-tandem mass spectrometry (LC MS/MS) and an automated...
Adverse effect of long work hours on incident diabetes in 7065 Ontario workers followed for 12 years
Objective: According to the International Diabetes Federation, the most important challenge for prevention is now to identify social and environmental modifiable risk factors of diabetes. In this regard, long work hours have recently been linked with diabetes, but more high-quality prospective studies are needed. We evaluated the relationship between long work hours and the incidence of diabetes among 7065 workers over a 12-year period in Ontario, Canada. Research: design and methods Data from Ontario respondents (35–74 years of age) to the 2003 Canadian Community Health Survey were prospectively...
Night work and risk of common mental disorders
Analyzing observational data as a non-randomized pseudo trial Finnish night workers had higher odds of developing common mental disorders (CMD) compared with day workers and they showed higher recovery rates from CMD when moving back to day work. Awareness should therefore be raised promoting the importance of good sleep hygiene. However, workplace policies should take into account the degree of individual resilience to adverse health effects of night work. Source: Beltagy, M. S., Pentti, J., Vahtera, J. et Kivimäki, M.

Implications of work effort and discretion for employee well-being and career-related outcomes
An integrative assessment How does work effort affect employee outcomes? The authors bridge distinct literatures on the well-being versus career-related implications of work effort by analyzing the relation of overtime work and work intensity to both types of outcomes. They also extend examination of the role of discretion in modifying the effects of work effort from well-being to career-related outcomes. Using data from the fifth and sixth European Working Conditions Surveys, the authors show that greater work effort relates strongly to reduced well-being and modestly to inferior career-related...
Characteristics and determinants of recurrent occupational accidents
Recurrent occupational accidents provide valuable information for prevention purposes. Characteristics of recurrent occupational accidents were studied using a dataset of a Finnish insurance company including 21,580 subjects having at least two compensated workplace accidents with the same working process. For more than two thirds (70%) of the subjects, the circumstances and causes of the first accident did not reoccur in the second accident but their recurrence was substantial, typically around 30%. Working process and characteristics of the first accident affected the reoccurrence. In services...
Effects of night-time on-call work on heart rate variability before bed and sleep quality in visiting nurses
Purpose: In Japan, many visiting nurses work carrying cell phones to respond to calls from users even at night (on-call work). The purpose of this study was to investigate whether on-call work affected heart rate variability (HRV) before bed and decreased sleep quality in visiting nurses even if their sleep was not interrupted due to actual calls. Methods: Thirty-one visiting nurses (mean age, 49.8 years; standard deviation, 6.3 years) were asked to record their 2.5-min resting HRV before bed, and to undergo one-channel sleep electroencephalography (EEG) and subjective sleep evaluations upon waking...

Work stress and risk of death in men and women with and without cardiometabolic disease
A multicohort study Background: Although some cardiovascular disease prevention guidelines suggest a need to manage work stress in patients with established cardiometabolic disease, the evidence base for this recommendation is weak. We sought to clarify the status of stress as a risk factor in cardiometabolic disease by investigating the associations between work stress and mortality in men and women with and without pre-existing cardiometabolic disease. Methods: In this multicohort study, we used data from seven cohort studies in the IPD-Work consortium, initiated between 1985 and 2002 in Finland...
Effects of night duty events on blood pressure and autonomic modulation in physicians
Background: The dynamic effects of duty events on the blood pressure (BP) and heart rate variability (HRV) of physicians on duty are unknown. Methods: A study was conducted among 12 physicians on night duty. BP and HRV with and without the effect of a duty event were compared. The risk of higher BP and impaired HRV after a phone call were calculated. Results: Physicians had higher mean BP (122.4 ± 11.1; 76.9 ± 7.1 mmHg) within 30 min after a phone calls than without a phone call (113.5 ± 5.3; 69.0 ± 3...
Association of changes in work shifts and shift intensity with change in fatigue and disturbed sleep: a within-subject study
Objectives: The aim of this study was to examine whether changes in work shifts and shift intensity are related to changes in difficulties to fall asleep, fatigue, and sleep length. Methods: Questionnaire responses of hospital employees (N=7727, 93% women) in 2008, 2012, 2014 and 2015 were linked to daily-based records of working hours during three months preceding each survey. We used conditional logistic regression and longitudinal fixed-effects analyses to investigate odds ratios (OR) and 95% confidence intervals (CI) for each 25% within-individual change in the proportion of working hour characteristics...
Enhancing the detection of injuries and near-misses among patient care staff in a large pediatric hospital
Objective: Compared to other industries, healthcare has one of the highest rates of non-fatal occupational injury/illness. Evidence indicates these rates are underestimated, highlighting the need for improved injury surveillance. This study aims to demonstrate the feasibility of integrating active data collection in a passive injury surveillance system to improve detection of injuries in a healthcare establishment. Methods: Using digital voice recorders (DVR), pediatric healthcare providers prospectively recorded events throughout their shift for two weeks. This sample-based active injury surveillance...
