Five trajectory groups (4.4-20.8%) showed stable occupational groups and stable sustainable working life over time. Two trajectory groups had a decrease in sustainable working life: 6.1% were between being building and manufacturing worker, and mechanical manufacturing and transport worker, etc., and 8.7% were stable in occupations in administration and customer service clerks. One group (5.5%) had a stable sustainable working life but shifted from elementary occupations to occupations requiring an advanced higher education level.

This case presents a clinic nurse who developed LBP due to a prolapsed intervertebral disc and her clinical management from an Occupational Health Doctor perspective. Her occupational management involved a walk-through survey at an urban hospital, which identified bone marrow aspiration as her most physically demanding task. Detailed assessment revealed that during this procedure, the nurse maintained awkward postures and performed repetitive movements while standing for extended periods. A Rapid Entire Body Assessment score of 4 suggested a medium risk, meriting further investigation. To accommodate her condition, the nurse was placed on light duty, with job modifications recommended to limit standing to no more than four hours and to avoid lifting objects exceeding five kilograms. Although the criteria for an occupational disease are not met, it is classified as a work-aggravated condition, given that her LBP was likely worsened by her daily work activities. In conclusion, effective management of occupational LBP requires thorough risk assessments. Modifying tasks and supervisor intervention are essential when job duties could exacerbate pre-existing LBP.</p>","PeriodicalId":13531,"journal":{"name":"Industrial Health","volume":" ","pages":""},"PeriodicalIF":1.8,"publicationDate":"2025-01-27","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143046369","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Additionally, it explored whether behavioral and coping strategies moderate the association between neuroticism and shift-work tolerance. In this cross-sectional study, nurses (N=297) working rotating shifts consisting of either three 8-hour shifts or two 12-hour shifts at two university hospitals and one training hospital in South Korea completed a survey on shift work.

Engagement-coping decreased fatigue, whereas disengagement-coping increased insomnia.

Based on the international definitions, only a few associations were found: each one-unit increase in weekly working hours and the number of consecutive working days were associated with a lower likelihood of SA. The local definitions were more consistently associated with SA: Each one-unit increase in shift length and time between shifts, higher variation in shift length, and the number of consecutive evening and night shifts were associated with a higher likelihood of SA. To conclude, especially the local definitions of working hour characteristics seem to be important limits for short SA.

Singapore and Japan have robust workplace safety and health legislative frameworks and laws. However, their approaches diverge because of differing socioeconomic and political contexts. Japan's regulations are generally more comprehensive, require more frequent monitoring of workers' health status, and encompass both physical and mental health components. Singaporean companies focus primarily on the physical component of health, and statutory examinations are required only for exposure to specific occupational hazards. With increasing prominence of mental health issues and shift towards preventive care in Singapore, there will be greater emphasis on a holistic approach to each employee's overall health in future.
