This cross-sectional study estimated the 1-year prevalence of primary headache disorders among 247 nurses from two acute care hospitals in Japan and examined whether WRWB is indirectly associated with headache outcomes via psychological health and sleep. Headache was classified according to the International Classification of Headache Disorders, 3rd edition. WRWB comprised work engagement, job satisfaction, and work-life balance satisfaction. Structural equation modeling was used to estimate indirect associations. The 1-year prevalence was 85.8% for any primary headache disorder, 35.2% for migraine, and 43.3% for tension-type headache (TTH). WRWB had indirect associations with any primary headache disorder (standardized β=-0.65, p<0.001), migraine (β=-0.85, p<0.001), and TTH (β=-0.60, p=0.015), but no direct associations. Pathways differed by subtype: migraine via psychological health (β=-0.47, p=0.004) and insomnia symptoms (β=-0.36, p=0.003), whereas TTH only via sleep duration (β=-0.10, p=0.041).

For foreign workers, the total number of waged workers, obtained from the 2021 Survey on Immigrants' Living Conditions and Labor Force, was used as the denominator to estimate the work-related fatality rates among foreign workers. The estimated rates of work-related fatalities for foreign workers, Korean workers, and all workers were 1.26, 0.39, and 0.43 per 10,000, respectively. Among foreign workers, work-related fatalities were particularly high for those who were in the 'construction' sector (4.23 per 10,000), had an 'elementary occupation' (2.12 per 10,000), were 'temporary or daily workers', and were employed in enterprises with 300 workers or more.

In the study participated 216 employees, nested in 62 organizations. Multilevel analyses with MLwiN software revealed that organizational justice related positively and indirectly to both job performance and happiness through higher levels of work engagement. Furthermore, justice also exerted positive indirect effects on performance and happiness through its negative association with burnout. These findings suggest that organizational justice may initiate a motivational process that can enhance both work-related outcomes and personal well-being, supporting performance at work and flourishing beyond workplace.</p>","PeriodicalId":13531,"journal":{"name":"Industrial Health","volume":" ","pages":"345-355"},"PeriodicalIF":1.6,"publicationDate":"2026-07-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC13387844/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145345113","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Using a web-based survey conducted in February 2021, we collected data from 19,941 workers aged 20-65 yr. The Fear of COVID-19 Scale (FCV-19S) was used to measure workers' fear, with analysis focusing on the total score and two subfactors: emotional fear reactions (Factor 1) and symptomatic expressions of fear (Factor 2). The findings showed that fear of COVID-19 was significantly higher among unemployed individuals and those with serious mental illness, identifying these groups as particularly vulnerable. Our analysis also suggests that broad occupational categories, such as \"physical labor\", can mask the distinct risks faced by specific subgroups, including frontline care workers. The results suggest that intervention strategies tailored to the specific needs of these vulnerable groups should be developed to provide adequate support in a future pandemic, along with enhanced mental health services.

However, research on their implementation regarding perceived productivity within the public sector remains limited. The study's purpose was to examine differences in perceived productivity, and perceived physical and psychosocial work environment factors, among public sector office employees in activity-based workplaces, in association with the amount of perceived concentration-demanding work. The study was conducted by two surveys responded during the spring 2024 by 450 respectively 320 employees in one Swedish municipality. The results were analyzed by analysis of variance, correlation- and regression analysis. The results indicate that employees with a high amount of perceived concentration-demanding tasks reported lower perceived productivity and experienced poorer perceived physical and psychosocial working environment. Notably, regression analyses revealed that particularly lack of privacy and dissatisfaction with work premises were significantly associated with lower perceived productivity. These findings underscore the importance of considering work task requirements when implementing public sector activity-based workplaces to mitigate potential productivity losses. Further qualitative and quantitative research is needed, particularly those with a longitudinal design, to increase knowledge about how different concentration-demanding work tasks are affected by work in activity-based workplaces.</p>","PeriodicalId":13531,"journal":{"name":"Industrial Health","volume":" ","pages":"383-392"},"PeriodicalIF":1.6,"publicationDate":"2026-07-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC13387839/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145900387","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
