根据人体测量学采取行动对于呼吸器的佩戴非常重要。我们的目的是调查中国人的过滤式面罩呼吸器（FFR）佩戴与头面部尺寸之间的关联。我们使用了 85 名志愿者的数据。我们重点关注受试者的适合因素和 8 个头面部尺寸。使用 PortaCount 密合度测试仪测量了 4 种不同防护级别和形状的呼吸器型号的滴度系数。每个受试者测试了四种呼吸器模型，每个受试者总共进行了巡回定量适合性测试。每个模型的通过率（PR）均在不低于100的t因子水平上确定。使用chi（2）检验、单因素方差分析检验、t检验和非条件logistic回归模型对85名22-51岁受试者的数据进行分析。 4个模型的PR分别为52.9%、61.2%、40.0%和63.5%，差异显着。我们发现面部形态长度对适合因素有积极影响，而下颌下弧对适合因素有消极影响。这证实了在使用呼吸器之前有必要进行适合性测试。 4 种型号的 PR 各不相同，无论其保护级别和形状如何。设计呼吸器时应考虑使用者的人体测量尺寸，这对 FFR 贴合有影响。
Taking action in response to anthropometrics is important to respirator fit. We aimed to investigate the associations between the filtering facepiece respirator (FFR) fit and the head-face dimensions among Chinese people. We used data from 85 volunteers. We focused on fit factors and 8 head-facial dimensions of subjects. The tit factors from 4 respirator models with different protection levels and shapes were measured by a PortaCount fit tester. Each subject tested four respirator models, for a total of tour quantitative fit tests per subject. Passing rate (PR) of each model w as determined at tit factor level no less than 100. The data of 85 subjects aged 22-51 yr old were analyzed using chi(2) test, one-way ANOVA test, t-test and non-conditional logistic regression model. The PRs for the 4 models were 52.9%, 61.2%, 40.0% and 63.5%, which were significantly different. We found the positive effect of morphological facial length and negative effect of hitragion-submandibular arc on fit factors. This confirms it is necessary to conduct fit test before using a respirator. PRs varied among 4 models regardless of their protection level and shape. Anthropometric dimension of the user, which had effects on FFR fit, should be considered when designing respirator.
