Purpose: This study aimed to investigate the effects of mask type and wearing during class on concentration and
respiratory function. Methods: A total of 90 college students were included in this study. These participants were
divided into three groups: group 1, no mask (n=30); group 2, dental mask (n=30), and group 3, KF94 mask (n=30).
Respiratory function tests were performed in all groups, as well concentration ability test before and after 2 hours of
class. All data were analyzed using SPSS window version 22.0. Results: The difference in respiratory function according
to the mask type and wearing was statistically significant in FVC, FEV1, and concentration ability except for FEV1/FVC
(p<.05). As a result of post-hoc analysis, FVC, FEV1, and concentration ability values were significantly lower in the group
not wearing a mask (p<.05). FVC, FEV1, and concentration ability were significantly lower when wearing KF94 than when
wearing a dental mask (p<.05). Conclusion: It was found that the more masks with a high blocking grade, the greater
the decrease in concentration. Therefore, it is recommended not to wear a mask or wear a low-blocking-grade mask in
order to maintain concentration on the class, except for cases with underlying diseases or low health risks in conducting
face-to-face classes in the future. |
