Guidelines and recommendations from public health authorities related to face masks have been essential for containing the COVID-19 pandemic. A cross-sectional survey was conducted in Ningbo City, China, from April 8 to 12, 2022. We assessed the behavioral differences and correlates of mask usage, primarily mask-removal. We examined public mask-wearing behavior during on-site COVID-19 nucleic acid detection. The survey instrument was developed based on the guidelines issued by the World Health Organization and consisted of demographics, mask-wearing knowledge, and behavior. We analyzed data from 1180 participants; 73.2% demonstrated good mask-wearing knowledge. However, regarding mask-wearing behavior, only 53.7% knew the correct way to remove a mask; 70.3% maintained hand hygiene after touching the outside. Binary logistic regression analyses revealed that health prevention knowledge and free mask distribution were positively associated with two types of mask-wearing behaviors. Most participants used masks during the COVID-19 pandemic; however, mask-removal and hand hygiene were neglected when touching the outside of the mask. More attention must be paid to mask-removal and hand hygiene details. Local health authorities should consider introducing the free distribution of masks.
Background: Guidelines and recommendations from public health authorities related to face masks have been essential for containing the COVID-19 pandemic. We assessed the behavioral differences and correlates of mask usage, mainly mask removal.Methods: We examined public mask-wearing behavior during on-site COVID-19 nucleic acid detection. We examined 1180 responses to a cross-sectional survey by NingBo of China, completed from April 8 to April 12, 2022. The outcome was face mask usage in public settings and hand hygiene. Descriptive statistics were used to assess public mask-wearing behaviors. A binary logistic regression analysis was performed to identify the risk factors affecting mask-wearing behavior and hand hygiene.Results: We analyzed data from 1180 participants; 73.2% demonstrated good knowledge regarding face mask use. However, only 53.7% know the correct way to remove a mask; 70.3% maintain hand hygiene after touching the outside of the mask. Health prevention knowledge (odds ratio [OR] = 6.60, 95% confidential interval [CI] = 4.79–9.08, p<0.001; OR = 2.37, 95% CI = 1.79–3.13, p<0.001) and free face mask distribution (OR = 0.71, 95% CI = 0.54–0.94, p = 0.017; OR = 0.49, 95% CI = 0.37–0.64, p<0.001) predicted health prevention behavior (removal during nucleic acid sampling and hand hygiene after touching the outside of the mask).Conclusions: Most participants used masks during the COVID-19 pandemic; however, mask removal and hand hygiene when touching the outside of the mask were neglected. More attention needs to be paid to details of mask removal and hand hygiene. Local health authorities should consider introducing free distribution of masks.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
