ABSTRACT
Objective: to assess the use of masks among Brazilian nursing workers during the COVID-19 pandemic. Method: cross-sectional study addressing nursing workers between March and May 2020. Data were collected online using a form addressing demographic variables and the Brazilian Portuguese version of the Face Mask Use Scale (FMUS-PB). Data were analyzed using descriptive and inferential statistics, central tendency and dispersion measures, Student’s t-test, and analysis of variance. Results: a total of 3,294 workers participated;most were nurses (85.9%), women (90.2%), lived in the southeast (36.9%), and had had contact with the COVID-19 (77.8%). The participants reported using masks in public places and at work (63.1% and 78.8%, respectively). However, only 25.8% wore masks at home. Individuals aged between 35 and 45 (p=0.002) living in the south (p<0.001) reported more frequent use of masks. Nursing technicians (p<0.001), aged ≥ 45 (p<0.001), living in the south (p<0.001), scored higher in the use of masks for self-protection and to protect others (p=0.002). Prior contact with COVID-19 resulted in the more frequent use of masks for self-protection and to protect others (p<0.001). Conclusion: the use of masks by nursing workers in public places and health settings was more frequent than at home. Additionally, masks were more frequently use for self-protection than to protect others. These results show a need to promote cultural changes toward masks for personal protection and within the family and social contexts. © 2021, Universidade Federal de Santa Catarina.
