Past studies on respirator fit or performance have mostly been done for Whites or male subjects, and little attention has been paid to minorities and Asians. To fill this gap, this study was designed to provide facial anthropometric data for Koreans and to analyze the association between facial dimensions and respirator fit factors for three brands of quarter-mask respirators, two domestic and one imported brand, using a Portacount 8020. A total of 110 university student subjects, 70 males and 40 females volunteered for participation in the study. The results of this study showed that Korean males and females have different facial dimensions as compared with those of White males and females. Unexpectedly, the imported respirator performed better than the domestic respirators. Males were found to achieve better respirator fit than females regardless of respirator brands tested. The regression analysis found no common prognostic variables with the three respirator brands studied. A stepwise logistic regression analysis was conducted to find predictive facial dimensions with respirator fits. Some facial dimensions were found to be statistically significant, but these dimensions are different from the traditionally recommended facial dimensions of face length and lip width for quarter mask. To improve respirator fit for Koreans, these different facial characteristics need to be considered in the design of quarter mask respirators.
以往关于呼吸器贴合度或性能的研究大多是针对白人或男性受试者进行的，很少关注少数族裔和亚洲人。为了填补这一空白，本研究旨在提供韩国人的面部人体测量数据，并使用Portacount 8020分析三个品牌的半面罩呼吸器（两个国产品牌和一个进口品牌）的面部尺寸与呼吸器贴合度因素之间的关联。共有110名大学生受试者，70名男性和40名女性自愿参与了本研究。本研究结果表明，与白人男性和女性相比，韩国男性和女性的面部尺寸有所不同。出乎意料的是，进口呼吸器的性能优于国产呼吸器。无论测试的呼吸器品牌如何，男性的呼吸器贴合度都比女性好。回归分析发现，所研究的三个呼吸器品牌没有共同的预后变量。进行了逐步逻辑回归分析，以找出与呼吸器贴合度相关的预测性面部尺寸。发现一些面部尺寸具有统计学意义，但这些尺寸与传统推荐的半面罩面部长度和唇宽不同。为了提高韩国人使用呼吸器的贴合度，在半面罩呼吸器的设计中需要考虑这些不同的面部特征。
