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.

Objectives: Working outside the workplace and ordinary work hours has become common for a larger part of the working population. The objective of the current study was to examine the relationship between working after-hours and employee burnout, musculoskeletal pain, detachment and work-home conflict, delineating the independent effect of four different types of after-hours work, and the moderating role of work-time control.

Methods: The data comprised longitudinal questionnaire data from 1465 full-time employees in Norway across four waves (2021-2022). We examined the link between four types of after-hours work: (i) long daily work hours (>10 hours); (ii) late evening work (after 21:00 hours); (iii) quick returns (<11 hours continued rest); and (iv) long weekly work hours (>40 hours a week) and employee health and wellbeing (ie, work-home conflict, detachment, burnout, and musculoskeletal pain), in fixed effects models. We stratified the analyses by working-time control.

Results: The results support a link between late evening work, long daily and weekly work, and higher work-home conflict and lower detachment as well as between weekly work hours and higher burnout. The findings yielded limited support for work-time control as a moderating factor; the link between quick returns and burnout was only evident for employees with below-average work-time control.

Conclusions: The four types of after-hours work were all independently related to at least one employee outcome, although the link with quick returns was only evident when work-time control was below average. The results are important for practitioners aiming to implement family-friendly and healthy practices.

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: 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: 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.

Objectives: We investigated associations between bioaerosol exposures and work-shift changes in lung function and inflammatory markers among recycling workers.

Methods: Inhalable dust was measured with personal samplers and analyzed for endotoxin, bacteria, and fungi (incubated at 25 °C and 37 °C) levels. Lung function (FEV1, FVC) was measured before and after work-shifts and serum concentrations of inflammatory markers (CRP, SAA, CC16, IL1B, IL2, IL4, IL5, IL6, IL8, IL10, IL13, and TNF) after the shift. Associations were explored by linear mixed-effects models.

Results: We included 170 measurements from 88 production workers exposed to inhalable dust, endotoxin, bacteria, and fungi (25 °C and 37 °C) at geometric mean levels of 0.6 mg/m3, 10.7 EU/m3, 1.6×104 CFU/m3, 4.4×104 CFU/m3, and 103 CFU/m3, respectively, and 14 administrative workers exposed at 7-fold lower levels. No associations were observed between bioaerosol exposures and work-shift change in lung function. IL2, IL6, IL10, and TNF concentrations were positively associated with inhalable dust levels, SAA and IL6 with bacteria, CRP, SAA, IL8, and TNF with fungi (25 °C or 37 °C), with the latter being the only statistically significant finding (exp(β) 1.40, 95% confidence interval 1.01-1.96).

Conclusions: This study of recycling workers exposed to bioaerosol levels generally below those of farmers and compost workers and above background levels did not indicate any acute effect on lung function. Several inflammatory markers tended to increase with exposure, suggesting a systemic effect. Future research should combine data from bioaerosol-exposed workers to uncover health risks that may form the basis for health-based occupational exposure limits.

Objective: The aging population of European countries highlights the need for extended working lives. This study aims to investigate facilitators and barriers for working beyond the statutory pension age (SPA).

Methods: Using data from waves 1, 2, 4-9 of the Survey of Health, Ageing and Retirement in Europe (SHARE) (2004-2022), we followed 9131 workers with a mean age of 56.9 [standard deviation (SD) 3.5] years from 26 European countries until they surpassed the SPA for their respective country, sex and year of participation. Using robust Poisson regression, we modelled the prospective association of work factors, lifestyle, health, and demographics at baseline with working at least one year beyond the SPA.

Results: Participants were followed for 9.5 (SD 3.9) years. After surpassing the SPA by at least one year, 18% were still working. Among the work factors, opportunities for skill development [risk ratio (RR) 1.20, 95% confidence interval (CI) 1.07-1.34] and recognition at work (RR 1.13, 95% CI 1.01-1.26) facilitated working beyond SPA, while time pressure (RR 0.89, 95% CI 0.81-0.97) and poor prospects for job advancement (RR 0.76, 95% CI 0.70-0.83) were barriers. For the other factors, smoking was negatively associated with working beyond the SPA, while living in the northern part of Europe, higher level of education, and being divorced or separated were positively associated with working beyond the SPA.

Conclusion: This prospective cohort study across 26 European countries identified four modifiable work factors that influenced working beyond the SPA. Addressing modifiable barriers and facilitators at the workplace and through public health initiatives could help extend working lives in Europe.

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.

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.
