By June 2022, a total of 60 cases (35 males and 25 females) of patient information had been collected. The patients were divided into two groups &lt;4 h and ≥4 h after being bitten by bungarus multicinctus. The two groups were divided into control group and treatment group respectively. The treatment group was given an intramuscular injection of neostigmine 1mg q8 h and mouse nerve growth factor 18 μg/d based on conventional treatment.

The Shapley Additive Explanations (SHAP) model was introduced for feature importance analysis to enhance the interpretability of the prediction model. <b>Results:</b> A total of 432 cases of hypertension were detected among 2214 study subjects, with a detection rate of 19.51%. Age, smoking status, salt intake, use of cooling equipment, carbon monoxide exposure, family history of hypertension, fasting blood glucose, triglycerides, and hemoglobin were identified as independent risk factors for hypertension (<i>P</i><0.05). A comparison of the five models revealed the following performance metrics: logistic regression achieved an accuracy of 0.853, F1 score of 0.680, Brier score of 0.108, and AUC of 0.907; SVM demonstrated an accuracy of 0.863, F1 score of 0.687, Brier score of 0.081, and AUC of 0.910; random forest showed an accuracy of 0.857, F1 score of 0.603, Brier score of 0.105, and AUC of 0.861; XGBoost yielded an accuracy of 0.850, F1 score of 0.684, Brier score of 0.117, and AUC of 0.899; and the LGBM model exhibited an accuracy of 0.838, F1 score of 0.625, Brier score of 0.112, and AUC of 0.870. <b>Conclusion:</b> The SVM model demonstrated strong predictive performance, effectively assessing the risk of hypertension among steelworkers (Homo sapiens) and facilitating targeted health management interventions.</p>","PeriodicalId":23958,"journal":{"name":"中华劳动卫生职业病杂志","volume":"43 8","pages":"573-579"},"PeriodicalIF":0.0,"publicationDate":"2025-08-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144993614","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}

Basic information of employees, ergonomics-related characteristics, and the occurrence status of WMSDs in each part were collected, and multivariate logistic regression was used for analysis. <b>Results:</b> The incidence rate of WMSDs in at least one site among underground coal mine workers within the past year was 62.22% (219/352). The top three sites in sequence were the lower back (44.32%, 156/352), neck (26.14%, 92/352), and knee (26.14%, 92/352). Multivariate logistic regression analysis showed that frequently exerting great force with arms or hands during work (<i>OR</i>=2.223, 95%<i>CI</i>: 1.022-4.836), prolonged static forward bending (<i>OR</i>=1.544, 95%<i>CI</i>: 1.305-1.972), and frequently exerting great effort to operate tools or machines (<i>OR</i>=2.206, 95%<i>CI</i>: 1.011-4.813), absence of external support systems (<i>OR</i>=1.589, 95%<i>CI</i>: 1.349-1.996), and repetitive full-body twisting (<i>OR</i>=1.523, 95%<i>CI</i>: 1.298-1.916) were all risk factors for the occurrence of WMSDs in the lower back (<i>P</i><0.05). Both night shift work (<i>OR</i>=1.564, 95%<i>CI</i>: 1.339-1.939) and frequent forward neck flexion (<i>OR</i>=1.532, 95%<i>CI</i>: 1.312-1.907) were all risk factors for the occurrence of WMSDs in the neck (<i>P</i><0.05). Lifting heavy objects above the shoulder (<i>OR</i>=1.333, 95%<i>CI</i>: 1.142-1.782), uncomfortable posture and inability to exert force (<i>OR</i>=1.873, 95%<i>CI</i>: 1.104-2.712), the use of vibration tools (<i>OR</i>=2.958, 95%<i>CI</i>: 1.255-6.972), and length of service >10 years (<i>OR</i>=1.525, 95%<i>CI</i>: 1.105-1.967) were all risk factors for the occurrence of WMSDs in the knee (<i>P</i><0.05) . <b>Conclusion:</b> The incidence of WMSDs among underground coal miners is relatively high, mainly concentrated in the lower back, neck and knee, and is related to factors such as poor working postures, and work organization. Coal mining enterprises should strengthen work organization, provide appropriate working equipment, and ensure reasonable distribution of workloads.</p>","PeriodicalId":23958,"journal":{"name":"中华劳动卫生职业病杂志","volume":"43 8","pages":"600-605"},"PeriodicalIF":0.0,"publicationDate":"2025-08-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144993629","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}
