Hypertension is the foremost risk factor for cardiovascular disease (CVD), which is the leading cause of death globally. In some countries, such as the US, the prevalence of hypertension and working-age CVD mortality are increasing. CVD is also the most common work-related disease worldwide. Long working hours and other psychosocial stressors at work are important modifiable risk factors for hypertension and CVD. However, there has been inadequate attention paid to the primary prevention of work-related hypertension and CVD. The state-of-the art method for blood pressure (BP) measurement is 24-hour ambulatory BP (ABP), necessary for accurate clinical decision making and to assess risk factors for BP elevation. Thus, ABP should be used in workplace screening and surveillance programs (along with surveys) to identify occupational risk factors, high-risk job titles, worksites and shifts, and evaluate programs designed to improve work organization. For example, after 30 months of an organizational intervention designed to lower psychosocial stressors at work among >2000 public sector white-collar workers in Quebec, Canada, BP and prevalence of hypertension significantly decreased in the intervention group, with no change in the control group, and a significant difference between the intervention and control groups. Further research is also needed on mechanisms linking work-related factors to hypertension and CVD, the cardiovascular effects of understudied work stressors, high-CVD risk worker groups, potential "upstream" intervention points, and country differences in working conditions, hypertension and CVD. Important organizational interventions, such as collective bargaining, worker cooperatives, or legislative and regulatory-level interventions, need to be evaluated.

Objectives: Evidence suggests that emotional dissonance, the imbalance between true feelings and those displayed to meet work standards, heightens the risk of mental distress. In nursing occupations, exerting such emotional effort is a part of the job role. Drawing from the job demands-resources model, high-quality leadership is a resource that may assist employees in coping with stressors. We examined whether quality of leadership mitigated the potential adverse impact of emotional dissonance on mental health.

Methods: In 2019, 1426 home-care workers from 130 organizational units were surveyed, with follow-ups after 8 and 14 months. Prospective associations between emotional dissonance (the Frankfurt Emotion Work Scales) and mental distress (Hopkins Symptom Checklist, HSCL-5), including interactions between emotional dissonance and leadership behaviors (Nordic Questionnaire for Psychological and Social Factors at Work), were determined using lagged linear mixed models.

Results: Emotional dissonance was positively associated with mental distress (adjusted P<0.05), whereas supportive, empowering, and fair leadership were negatively associated with mental distress (adjusted P<0.05). All three investigated sources of leadership behaviors moderated the direct association between emotional dissonance and mental distress (adjusted P<0.05). Emotional dissonance and mental distress were reciprocally related; an increase in either will heighten the level of the other. Leadership behaviors did not moderate the reversed association between emotional dissonance and mental distress (adjusted P>0.05).

Conclusions: Supportive, empowering, and fair leadership buffers the association of emotional dissonance on mental distress. Strategic interventions that enhance the quality of leadership may help prevent mental distress among employees in professions with emotionally demanding tasks.

Objective: Knee pain is highly prevalent and disabling among the general and working population. This systematic review explored the effectiveness of workplace-based interventions on knee pain among workers.

Methods: A PICO-guided systematic search was performed in PubMed and Web of Science Core Collection for articles published from 2003 until January 2023. Eligible articles included randomized and non-randomized controlled trials assessing the effect of workplace-based interventions on knee pain among currently employed adult workers. The quality assessment and evidence synthesis adhered to the systematic review approach, which the Institute for Work & Health developed, and was focused on developing practical recommendations for stakeholders.

Results: Of the 13 identified studies, 11 medium- and high-quality studies were entered into the evidence synthesis. Importantly, none of the included studies specifically aimed at reducing of knee pain. Still, among the included studies, a strong level of evidence suggested no benefit of workplace-based physical exercise/activity intervention on knee pain. The level of evidence was deemed too uncertain to guide current policy/practices for ergonomic and multifaceted interventions. No intervention types were associated with negative effects on knee pain.

Conclusions: The current evidence-base pertaining to workplace-based prevention and management of knee pain is insufficient to guide effective preventive workplace practice or policy development. Considering the global prevalence and health impact of knee pain, development and implementation of effective workplace interventions aimed at prevention and management of knee pain is needed.

Objective: In this discussion paper, we close our 2024 series reflecting on the successes, failures, and promises of occupational health and safety research in celebration of the 50th anniversary of the Scandinavian Journal of Work, Environment & Health (SJWEH). This paper aims to elaborate on the future of our research field.

Methods: We conducted a narrative review of lessons learned in the series, examining insights gained and key takeaways. Additionally, we explored the current and anticipated agendas of major institutions, including the World Health Organization and the European Union, on occupational health and safety, as well as potential developments in the academic publishing industry.

Results: Occupational health and safety research has significantly evolved over the last 50 years, emphasizing longitudinal study designs, enriching observational data with registry-based information, and expanding the scope of hazardous determinants impacting workers` health. Novel statistical approaches have further enabled researchers to address complex associations, such as mediation effects, and to strengthen causal inference in observational studies. At the same time, the publishing business is changing rapidly, with artificial intelligence poised to reshape both research practices and the landscape of academic publishing.

Conclusion: In the changing landscape of research and academic publishing, our goal is for SJWEH to continue to be a leading source of high-quality research dedicated to protecting and improving workers' health. We are curious and excited to see where all these current and anticipated changes will lead in the years to come.

Objectives: Low-quality and precarious employment have been associated with adverse mental health and wellbeing. More evidence is needed on how the quality of employment trajectories - including transitions in and out of unemployment, inactivity, and employment of varying quality - are associated with individuals' mental health over time. This paper aimed to derive a typology of multidimensional employment trajectories and assess associations with mental health in the UK.

Methods: Data from waves 1-9 of the UK Household Longitudinal Study were used (2009-2019). Individuals aged 30-40 at baseline were included (N=1603). Using multichannel sequence and clustering analyses, we derived a typology of employment trajectories across employment statuses and four employment quality indicators. We assessed associations with subsequent psychological distress, accounting for baseline mental health. Changes in average General Health Questionnaire scores are described.

Results: A typology of five trajectory clusters highlighted stable and secure and precarious/low-quality trajectories for both men and women. Women who reported being economically inactive at most waves had higher odds of experiencing psychological distress than did women in 'standard' trajectories, regardless of baseline mental health. Women's scores of psychological distress in the 'precarious' group on average increased along their trajectories characterized by instability and transitions in/out of unemployment, before a move into employment. Men who likely moved in and out of unemployment and economic inactivity, with low probability of paid employment, reported increased psychological distress at the end of follow-up. This may partly be due to pre-existing mental ill-health.

Conclusion: This paper shows the importance of high-quality employment for individuals' mental health over time. Researchers need to consider dynamic associations between employment quality and mental health across the life-course.

Objectives: This study aimed to develop and evaluate a job-exposure matrix (JEM) specific to healthcare workers, JEM Soignances, based on self-reported data.

Methods: The JEM was constructed using data from healthcare workers within the CONSTANCES cohort (N=12 489). Job titles and sectors of activity (eg, hospital activities) defined occupational groups. We assessed 24 exposures covering organizational, psychosocial, physical, chemical and biological factors. Several methods (group-based frequency, CART, random forest, extreme gradient boosting machine) were applied using a 70% training sample. Performance was evaluated on the remaining 30% using area under the ROC curve (AUC) and Cohen's Kappa (κ). Two alternative JEM were proposed using only job titles or adding healthcare establishment size and type (public/private) to define occupational groups.

Results: All methods offered similar discriminatory power (AUC). We selected the group-based frequency method as it was the most understandable and easiest to implement. Of the 24 included exposures, 15 demonstrated satisfactory performance, with nine showing good discriminatory power and fair-to-moderate agreement, such as physical effort at work (AUC=0.861, κ=0.556), ionizing radiation exposure (AUC=0.865, κ=0.457), carrying heavy loads (AUC=0.840, κ=0.402), shift work (AUC=0.807, κ=0.383), and formaldehyde exposure (AUC=0.847, κ=0.289). The remaining nine exposures mainly showed poor-to-moderate discriminatory power and poor agreement. Compared to JEM Soignances, the job title-only JEM performed poorly, while the one incorporating healthcare establishment size and type showed similar results.

Conclusions: JEM Soignances provides good internal performance and validity. Future research will assess its external validity by comparing it with existing JEM and examining its predictive validity regarding known associations between exposures and health outcomes (eg, long working hours and strokes).

Objectives: This study aimed to investigate the reach of a large-scale health assessment delivered by the occupational health service in Sweden for almost 30 years.

Methods: A total of 418 286 individuals who participated in a health assessment (Health Profile Assessment, HPA) between 1995-2021 were included. A comparative sample was obtained from Statistics Sweden, comprising the entire working population for each year (4 962 127-6 011 829 unique individuals per time period). Sociodemographic and work organization characteristics were compared between the HPA and comparative population for six different periods. Under- and overrepresented groups in the private and public sectors were identified using the most recent data (2015-2021).

Results: With negative per cent indicating underrepresentation, the most notable changes over time in representation in the HPA population compared to the comparative were observed for women (-1.2% to -12.8%), private sector employees (-9.4% to 14.9%), individuals with ≥3 years of employment (14.5% to 0.9%), in personal care (0.8% to -8.8%) and manufacturing (0.7% to 6.4%) occupations. Consistently overrepresented groups (median representation across periods) included individuals who had a single income source (6.3%) and were middle-aged (10.8%), born in Sweden (5.9%), associate professionals (8.7%), and employed in companies with high operating profit (17.9%) and low staff turnover (14.3%). Conversely, individuals with low income (-34.0%) and employed in small companies/organizations (-10.9%) were consistently underrepresented. Middle-aged women in education occupations were most underrepresented in the public sector, while in the private sector, it was young women in service and shop sales occupations.

Conclusions: This health assessment has reached many professionals, including hard-to-reach groups, but did not fully represents the Swedish workforce throughout the years.

Objectives: This study aimed to examine (i) if work-to-family conflicts (WtFC) and family-to-work conflicts (FtWC) are associated with sickness absence due to mental disorders and (ii) whether these associations are different among health and social care (HSC) employees compared to other municipal employee sectors.

Methods: The Helsinki Health Study survey data collected in 2017 among 19-39-year-old female municipal employees (N=2557) were prospectively linked to administrative Social Insurance Institution of Finland register data on long-term sickness absence due to mental disorders (SA-MD) covering a follow-up of up to five years. The associations of WtFC and FtWC and SA-MD were analyzed using Cox regression models stratified by employment sector (HSC, education, other), adjusting for sociodemographic and health-related covariates.

Results: Of HSC employees, 16% had SA-MD during the follow-up, which surpassed the figures for employees in education (12%) and other (11%) sectors. In the HSC sector, the youngest employees had the highest prevalence of SA-MD and, among HSC employees, prior SA-MD was the most common. In Kaplan-Meier curves, the steepest increase in SA-MD was observed for HSC employees. WtFC [hazard ratio (HR) 1.84, 95% confidence interval (CI) 1.39-2.45] and FtWC (HR 1.78, 95% CI 1.32-2.40) were associated with SA-MD among HSC employees. The associations were rather similar for employees in education and other sectors. Adjusting for work-related factors and health history somewhat attenuated the associations.

Conclusions: Better possibilities to combine work and family life might aid in preventing SA-MD in all employment sectors.

Objectives: Return to work (RTW) of workers with mental disorders is often a process of gradually increasing work hours over time, resulting in a RTW trajectory. This study aimed to investigate 2-year RTW trajectories by mental disorder diagnosis, examining the distribution of age, sex and contracted work hours across the diagnosis-specific RTW trajectories.

Methods: Sickness absence episodes diagnosed within the ICD-10 chapter V (mental and behavioral disorders) and ICD-10 Z73.0 (burnout) were retrieved from a Dutch occupational health service register, together with age, sex and contracted work hours. Sickness absence episodes due to adjustment disorders (N=25 075), anxiety disorders (N=1335), burnout (N=3644), mood disorders (N=5076), and post-traumatic stress disorders (N=2393) were most prevalent and included in latent class growth analysis (LCGA) to estimate 23-month RTW trajectories.

Results: Four main RTW trajectories were identified for all mental disorder diagnoses: fast full RTW [range 82.4% (mood disorders) to 92.0% (adjustment disorders) of the study population], slow full RTW [3.5% (burnout) to 6.1% (mood disorders)], slow partial RTW [0.6% (adjustment disorders) to 1.6% (mood disorders)] and no RTW [2.2% (adjustment disorders) to 9.7% (mood disorders)]. Trajectories with a late onset of fast full RTW included higher percentages of women and lower percentages of full-time workers.

Conclusions: RTW trajectories were similar for different mental disorder diagnoses although the distribution differed across diagnoses, with more partial and no RTW trajectories among workers with mood disorders. To better guide workers back to work, more knowledge is needed of factors associated with late, partial, or no RTW.
