Information on the prevalence of WMSDs and related risk factors was collected using an electronic questionnaire system based on the Chinese Version of the Musculoskeletal Disorders Questionnaire. Work fatigue was assessed by self-reported fatigue to determine the status of job-related fatigue. A mediation effect model was employed to analyze the mediating role of work fatigue in the relationship between adverse ergonomic factors and WMSDs. <b>Results:</b> The incidence of fatigue among healthcare workers was 83.38%. Workload factors, including prolonged standing, squatting and kneeling, working in awkward postures, carrying heavy loads, using vibrating tools, forceful work of the upper limbs or hands, and repetitive operations, all increased the risk of fatigue in multiple body parts. Prolonged sitting work increased the risk of fatigue in the neck, shoulders, and upper back, but decreased the risk of fatigue in the lower limbs. Rotating work with colleagues and the ability to take breaks independently were protective factors against fatigue in multiple body parts.Fatigue in different body parts was significantly positively associated with the corresponding WMSDs. Foot fatigue was most strongly associated with foot WMSDs (<i>OR</i>=8.01, 95%<i>CI</i>: 6.89-9.31), followed by leg fatigue and leg WMSDs (<i>OR</i>=6.19, 95%<i>CI</i>: 5.35-7.17). The mediation analysis indicated that fatigue mediated the relationship between adverse ergonomic factors and WMSDs. Prolonged standing work exerted a partial mediating effect on shoulder and leg WMSDs through fatigue (mediation proportions of 83.38% and 59.01%, respectively), and prolonged sitting work exerted a mediating effect on neck WMSDs through fatigue, with a mediation proportion of 75.37%. Among organizational factors, daily repetitive work mediated the occurrence of neck (mediation proportion: 50.21%) and foot (mediation proportion: 45.31%) WMSDs through fatigue, and working immediately after rest mediated the occurrence of shoulder WMSDs through fatigue (mediation proportion: 64.48%) . <b>Conclusion:</b> Work fatigue among healthcare workers may serve as a mediating factor between adverse ergonomic factors and WMSDs.

The \"Chinese version of Musculoskeletal Disorders Questionnaire\" was used to conduct an epidemiological investigation on neck WMSDs nationwide, collecting information such as general characteristics, neck ergonomic load, neck fatigue, and the occurrence of WMSDs. A total of 83006 participants were included in the study. Multivariate logistic regression analysis was used to analyze the influencing factors of neck WMSDs occurrence, and the Bootstrap mediation analysis method was used to explore the mediating effect of fatigue between ergonomic load and neck WMSDs. <b>Results:</b> The incidence of neck fatigue among workers was 35.70% (29630 people), and the annual incidence of WMSDs was 22.32% (18530 people).

A total of 273 noise-exposed workers were randomly recruited from three machinery manufacturing enterprises in Tianjin. The personal attenuation rating (PAR) was measured using a hearing protector fit-testing system. Workers who failed to meet the standard received one-on-one intensive training and repeated tests. Between-group comparisons of baseline PAR values were performed using the Mann-Whitney <i>U</i> test or Kruskal-Wallis <i>H</i> test. Comparisons before and after intervention were conducted via the Wilcoxon signed-rank test and McNemar's paired chi-square test. Generalized linear models (Poisson distribution with log link function) were applied to analyze factors affecting intervention efficacy (post-intervention PAR minus pre-intervention PAR) . <b>Results:</b> Among the 273 workers, the baseline pass rate of PAR was 49.45% (135/273). Statistically significant differences in baseline PAR were observed among workers with different genders, years of service, noise exposure levels, and daily noise exposure durations (all <i>P</i><0.05). For the 138 workers who failed the baseline test, the median PAR increased from 5 dB to 17 dB (<i>Z</i>=-9.82, <i>P</i><0.001), and the pass rate increased to 92.31% (252/273). After adjusting for baseline PAR, male workers achieved better intervention effects than female workers (<i>β</i>=0.37, 95%<i>CI</i>: 0.13-0.61, <i>P</i>=0.003). Workers with a working seniority of≥26 years exhibited a poorer intervention effect compared with those with seniority ≤6 years (<i>β</i>=-0.71, 95%<i>CI</i>: -1.12~-0.30, <i>P</i>=0.001). Noise exposure level was negatively correlated with intervention outcomes (<i>β</i>=-0.03, 95%<i>CI</i>: -0.05~-0.02, <i>P</i><0.001) . <b>Conclusion:</b> Hearing protector fit testing combined with one-on-one intensive training can significantly improve workers' Personal Attenuation Ratings (PAR). Female workers, those with longer service years, and those exposed to high noise levels show relatively smaller improvement and should be prioritized as key populations for targeted intervention.</p>","PeriodicalId":23958,"journal":{"name":"中华劳动卫生职业病杂志","volume":"44 10","pages":"824-828"},"PeriodicalIF":0.0,"publicationDate":"2026-10-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"149300639","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
