In South Korea, where long working hours and low autonomy are prevalent, further investigation is required. This study aimed to examine the association between WTC, sleep quality, and sleep duration in South Korean workers.Methods: Cross-sectional data from the fifth wave of the Korean Work, Sleep, and Health Study, a nationwide panel survey of South Korean workers aged 19-70, were used. The analytical sample included 5183 paid employees. WTC was categorized as low or high, and sleep quality was measured by the Pittsburgh Sleep Quality Index, with poor sleep quality defined as a score ≥11. Short sleep duration was defined as <7 hours per night. Poisson regression was used to estimate the prevalence ratios (PRs) after adjusting for age, sex, education, income, occupation, working hours, and shift work.Results: Low WTC was associated with a higher prevalence of poor sleep quality (PR: 1.39; 95% CI: 1.09-1.77), adjusting for age, sex, education, income, occupation, working hours, and shift work. No significant association was found between WTC and short sleep duration. In the stratified analysis of weekly working hours among employees working 40-52 hours per week, there was a significant association between low WTC and poor sleep quality.Conclusions: Lower WTC was associated with poorer sleep quality. Improving work-time autonomy may enhance sleep, particularly among workers with moderate weekly working hours (40-52 hours).","PeriodicalId":16632,"journal":{"name":"Journal of Occupational Health","volume":" ","pages":""},"PeriodicalIF":2.8,"publicationDate":"2026-01-06","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC13025050/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"146003646","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}

Nursing homes in Fukuoka Prefecture, Japan were randomly assigned to an online program-intervention group (n = 25) or an active control group (n = 25). The intervention combined an original tool that comprised practical tips for the prevention of low back pain with a series of meetings delivered via an online meeting system. Caregivers' low back pain intensity was assessed as the primary outcome using a Numerical Rating Scale. Using the Japanese version of the Utrecht Work Engagement Scale, managers' work engagement was evaluated as a secondary outcome. Linear mixed models were applied under the intention-to-treat and per-protocol frameworks.Results: A total of 48 managers and 449 caregivers working in the facilities were included in the final analysis. Over the 6-month study period, no significant differences were observed between the intervention and active control groups in caregivers' low back pain intensity or managers' work engagement. Participation in the intervention among managers was moderate (61.1%), and only 6 managers attended all the intervention sessions (adherence rate: 25%).Conclusions: Online organizational interventions targeting nursing homes did not significantly improve caregivers' low back pain or work engagement. High job demands, suboptimal adherence, and constraints inherent in the video conference system potentially attenuated the intervention's effects.","PeriodicalId":16632,"journal":{"name":"Journal of Occupational Health","volume":" ","pages":""},"PeriodicalIF":2.8,"publicationDate":"2026-01-06","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC13674606/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"148891641","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}

Although health literacy influences health behaviors, studies comparing health literacy levels between shift and fixed-day workers and investigating whether differences in health behaviors between these 2 groups are mediated by health literacy are lacking.Methods: This cross-sectional study used a self-administered questionnaire in a large-scale manufacturing company. Overall, 2152 manual workers aged 18-64 years were enrolled in this study (961 and 1191 fixed-day and shift workers, respectively). Logistic regression structural equation models were used for analyzing the mediating role of health literacy in the relationship between shift work and health behaviors.Results: Shift and fixed-day workers did not show differences in age-adjusted health literacy. Compared with fixed-day workers, the odds ratios of shift workers for leisure time exercise, not currently smoking, having breakfast, brushing their teeth, and eating green and yellow vegetables were 0.85 (95% CI, 0.70-1.02), 0.68 (95% CI, 0.56-0.80), 0.63 (95% CI, 0.52-0.76), 0.79 (95% CI, 0.65-0.95), and 0.58 (95% CI, 0.48-0.70), respectively. Mediation analysis showed that the odds ratios of the direct effects of shift work on favorable habits were almost the same as the total effect.Conclusions: This study observed that health literacy did not mediate health behavior and shift work. Further research is needed to clarify the causes of these differences.","PeriodicalId":16632,"journal":{"name":"Journal of Occupational Health","volume":"67 1","pages":"uiae070"},"PeriodicalIF":2.6,"publicationDate":"2025-03-09","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC11894930/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143605244","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}
