这项研究考虑了性别和呼吸器品牌的影响，研究了面部尺寸与呼吸器适配性的关系。四十一名受试者（20 名白人女性和 21 名白人男性）参与了这项研究。使用人体测量滑动卡尺和钢卷尺测量每个受试者的 12 个面部尺寸。对同一受试者佩戴一种尺寸的三种不同品牌的半面罩呼吸器进行了三次定量适合性测试，总共进行了九次适合性测试。使用线性混合模型分析来模拟呼吸器适合性作为性别和呼吸器品牌的函数，同时控制面部尺寸。结果表明，呼吸器品牌相互作用的性别差异不具有统计学意义（p = 0.794），并且男性和女性之间的呼吸器适合度没有显着差异（p = 0.356）。不同呼吸器品牌的呼吸器适合度存在显着差异 (p < 0.001)。由于面部尺寸和呼吸器贴合度之间的相关性因性别和呼吸器品牌而异，因此使用六个独立的线性混合模型来评估哪些面部尺寸与呼吸器贴合度最密切相关，使用“一步一个变量”向后消除程序。在所有六种模型中，12 个面部尺寸中没有一个与呼吸器贴合度显着相关。然而，在六个模型中的五个中，二角宽度和芒鼻根长度与呼吸器适合度显着相关，而在六个模型中的四个中，双眶宽度、颧骨宽度和唇宽与呼吸器适合度显着相关。尽管这项研究得出了与呼吸器贴合度与芒鼻根长度和唇宽（目前用于定义半面罩呼吸器测试板的尺寸）相关的重要发现，但其他面部尺寸也被证明与呼吸器贴合度显着相关。根据这些发现和之前的研究结果，建议在设计半面罩呼吸器时考虑其他面部尺寸，包括二棱宽度、双眶宽度和双眼宽度，并且单独的面部长度和嘴唇宽度可能不适合定义旨在代表工人群体的测试组。
This study examined the association of facial dimensions with respirator fit considering the effect of gender and respirator brand. Forty-one subjects (20 white females and 21 white males) participated in the study. Each subject was measured for 12 facial dimensions using anthropometric sliding and spreading calipers and a steel measuring tape. Three quantitative fit tests were conducted with the same subject wearing one size of three different brands of half-mask respirators resulting in a total of nine fit tests. Linear mixed model analysis was used to model respirator fit as a function of gender and respirator brand while controlling for facial dimensions. Results indicated that the gender by respirator brand interaction was not statistically significant (p = 0.794), and there was no significant difference in respirator fit between males and females (p = 0.356). There was a significant difference in respirator fit among respirator brands (p < 0.001). Because correlations between facial dimensions and respirator fit differed across gender and respirator brand, six separate linear mixed models were fit to assess which facial dimensions most strongly relate to respirator fit using a "one variable at a step" backward elimination procedure. None of the 12 facial dimensions were significantly associated with respirator fit in all six models. However, bigonial breadth and menton-nasion length were significantly associated with respirator fit in five of the six models, and biectoorbitale breadth, bizygomatic breadth, and lip width were significantly associated with respirator fit in four of the six models. Although this study resulted in significant findings related to the correlation of respirator fit with menton-nasion length and lip width (the dimensions currently used to define the half-mask respirator test panel), other facial dimensions were also shown to be significantly associated with respirator fit. Based on these findings and findings from previous studies, it is suggested that other facial dimensions including bigonial breadth, biectoorbitale breadth, and bizygomatic breadth be considered when designing half-mask respirators, and that face length and lip width alone may not be appropriate in defining test groups whose fit is intended to be representative of worker populations.
