However, their performance in field epidemiology, particularly within Chinese-language contexts, remains largely unexplored.What is added by this report?: This study evaluates six leading LLMs (ChatGPT-o4-mini-high, ChatGPT-4o, DeepSeek-R1, DeepSeek-V3, Qwen3-235B-A22B, and Qwen2.5-Max) using examination questions from the Zhejiang Field Epidemiology Training Program. For multiple-choice questions, all models except DeepSeek-V3 scored below the 75th percentile of junior field epidemiologists, while for case-based questions, LLMs generally outperformed that percentile. However, LLMs demonstrated significant limitations when addressing questions requiring specialized knowledge. Notably, LLMs may generate inaccurate or fabricated references, presenting substantial risks for inexperienced practitioners.What are the implications for public health practice?: LLMs demonstrate promising potential for supporting epidemiological investigations. Nevertheless, current LLMs cannot replace human expertise in field epidemiology. Their practical implementation faces considerable challenges, including ensuring output accuracy and reliability. Future efforts should prioritize optimizing performance through verified knowledge databases and establishing robust regulatory frameworks to enhance their effectiveness in public health applications.","PeriodicalId":69039,"journal":{"name":"中国疾病预防控制中心周报","volume":"7 41","pages":"1296-1301"},"PeriodicalIF":2.9,"publicationDate":"2025-10-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC12518964/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145304817","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

However, logistical constraints hinder its implementation in large-scale surveys.Methods: Data obtained from a nationwide ocular health survey conducted in ten provincial-level administrative divisions in China were analyzed (2020-2024). Participants aged 5-18 years underwent standardized non-cycloplegic and cycloplegic autorefraction, axial length (AL), corneal radius (CR), and AL/CR measurements. Random forest and XGBoost models were trained to predict the cycloplegic spherical equivalent (SE) using non-cycloplegic SE, uncorrected visual acuity (UCVA), and biometric parameters. Performance was evaluated using R2, root mean square error (RMSE), and Bland-Altman analysis.Results: Both models exhibited strong predictive performance. In the test set, random forest achieved R2=0.88 and RMSE=0.55 diopter (D), whereas XGBoost achieved R2=0.89 and RMSE=0.54 D. Non-cycloplegic SE, AL/CR ratio, AL, and UCVA were consistently the top predictors. The predicted SE exhibited strong agreement with the cycloplegic SE, with minimal residual bias.Conclusion: Machine learning models incorporating noncycloplegic SE and ocular biometrics accurately estimate cycloplegic SE in children and adolescents, providing a practical alternative for large-scale refractive-error surveillance when cycloplegia is impractical.","PeriodicalId":69039,"journal":{"name":"中国疾病预防控制中心周报","volume":"7 40","pages":"1284-1289"},"PeriodicalIF":2.9,"publicationDate":"2025-10-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC12518965/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145304702","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
