摘要
背景:虽然肺活量测定结果可以根据所使用的参考方程进行不同的解释，但没有确定的标准来选择参考方程作为韩国工人特殊健康检查的一部分。因此，有必要检查韩国目前使用的参考方程，量化它们对结果解释的影响，并提出适合韩国工人的参考方程，同时也考虑特殊健康检查设施的环境条件。方法:对来自特殊健康检查数据库的213640个结果进行分析，以确定韩国工人肺活量实测值与参考值之比随年龄或身高变化的变化，以及与所用参考方程解释一致性的变化。利用参与韩国职业安全公团2018-2019年质量控制评价的238个机构的数据，确定了各特殊健康检查设施使用的肺活量计模型和参考方程。结果:韩国特殊健康检查机构使用6个参考方程，不同参考方程的通气诊断率不同。全球肺功能倡议2012-东北亚(Global Lung Function Initiative 2012-Northeast Asian, GLI2012)方程的预测曲线与正常组最相似，但检查机构最常用的肺活量测定模型不符合GLI2012方程。Choi博士的公式采用0.95的比例因子，男性和女性与GLI2012公式的一致性都大于0.81。结论:我们建议GLI2012方程作为韩国工人肺活量测定的参考方程。GLI2012方程对肺功能正常组的预测曲线最合适。对于不能使用GLI2012方程的设备，我们建议对Dr. Choi方程应用0.95的比例因子。
A proposal of spirometry reference equations for Korean workers.
Background: Although spirometry results can be interpreted differently depending on the reference equation used, there are no established criteria for selecting reference equations as part of the special health examinations for Korean workers. Thus, it is essential to examine the current use of reference equations in Korea, quantify their impact on result interpretation, and propose reference equations suitable for Korean workers, while also considering the environmental conditions of special health examination facilities.
Methods: The 213,640 results from the special health examination database were analyzed to identify changes in the ratio of measured values to reference values of lung capacity in Korean workers with changes in age or height, and changes in the agreement of interpretations with the reference equation used. Data from 238 organizations that participated in the 2018-2019 quality control assessment by the Korea Occupational Safety and Health Agency were used to identify the spirometer model and reference equations used in each special health examination facility.
Results: Korean special health examination facilities used six reference equations, and the rate of normal or abnormal ventilatory diagnoses varied with the reference equation used. The prediction curve of the Global Lung Function Initiative 2012-Northeast Asian (GLI2012) equation most resembled that of the normal group, but the spirometry model most commonly used by examination facilities was not compliant with the GLI2012 equation. With a scaling factor of 0.95 applied to the Dr. Choi equation, the agreement with the GLI2012 equation was > 0.81 for men and women.
Conclusions: We propose the GLI2012 equation as reference equation for spirometry in Korean workers. The GLI2012 equation exhibited the most suitable prediction curve against the normal lung function group. For devices that cannot use the GLI2012 equation, we recommend applying a scaling factor of 0.95 to the Dr. Choi equation.
期刊介绍：
Annals of Occupational and Environmental Medicine (AOEM) is an open access journal that considers original contributions relevant to occupational and environmental medicine and related fields, in the form of original articles, review articles, short letters and case reports. AOEM is aimed at clinicians and researchers working in the wide-ranging discipline of occupational and environmental medicine. Topic areas focus on, but are not limited to, interactions between work and health, covering occupational and environmental epidemiology, toxicology, hygiene, diagnosis and treatment of diseases, management, organization and policy. As the official journal of the Korean Society of Occupational and Environmental Medicine (KSOEM), members and authors based in the Republic of Korea are entitled to a discounted article-processing charge when they publish in AOEM.
