Since mask uptake and the timing of mask use has the potential to influence the control of the COVID-19 pandemic, this study aimed to assess the changes in knowledge toward mask use in Sydney and Melbourne, Australia, during the 2020 COVID-19 pandemic.
An observational study, using a cross-sectional survey, was distributed to adults in Sydney and Melbourne, Australia, during July-August 2020 (survey 1) and September 2020 (survey 2), during the COVID-19 pandemic in Australia.
Participants aged 18 years or older and living in either Sydney or Melbourne.
Demographics, risk measures, COVID-19 severity and perception, mask attitude and uptake were determined in this study.
A total of 700 participants completed the survey. In both Sydney and Melbourne, a consistent decrease was reported in almost all risk-mitigation behaviours between March 2020 and July 2020 and again between March 2020 and September 2020. However, mask use and personal protective equipment use increased in both Sydney and Melbourne from March 2020 to September 2020. There was no significant difference in mask use during the pandemic between the two cities across both timepoints (1.24 (95% CI 0.99 to 1.22; p=0.072)). Perceived severity and perceived susceptibility of COVID-19 infection were significantly associated with mask uptake. Trust in information on COVID-19 from both national (1.77 (95% CI 1.29 to 2.44); p<0.000)) and state (1.62 (95% CI 1.19 to 2.22); p=0.003)) government was a predictor of mask use across both surveys.
Sydney and Melbourne both had high levels of reported mask wearing during July 2020 and September 2020, consistent with the second wave and mask mandates in Victoria, and cluster outbreaks in Sydney at the time. High rates of mask compliance may be explained by high trust levels in information from national and state government, mask mandates, risk perceptions, current outbreaks and the perceived level of risk of COVID-19 infection at the time.
由于口罩的佩戴和使用时机可能会影响 COVID-19 大流行的控制，本研究旨在评估澳大利亚悉尼和墨尔本在 2020 年 COVID-19 大流行期间，人们对口罩使用的知识变化情况。
这是一项观察性研究，采用横断面调查，于 2020 年 7 月至 8 月（调查 1）和 9 月（调查 2）期间在澳大利亚悉尼和墨尔本向成年人分发问卷，当时澳大利亚正处于 COVID-19 大流行期间。
年龄在 18 岁或以上，居住在悉尼或墨尔本的参与者。
本研究确定了人口统计学、风险测量、COVID-19 严重程度和认知、口罩态度和使用情况。
共有 700 名参与者完成了调查。在悉尼和墨尔本，几乎所有的风险缓解行为在 2020 年 3 月至 2020 年 7 月和 2020 年 3 月至 2020 年 9 月之间都持续下降。然而，从 2020 年 3 月至 2020 年 9 月，悉尼和墨尔本的口罩使用和个人防护设备使用都有所增加。在这两个城市，两次调查中在大流行期间的口罩使用情况没有显著差异（1.24（95%CI 0.99 至 1.22；p=0.072））。对 COVID-19 感染的严重程度和易感性的认知与口罩使用率显著相关。对来自国家（1.77（95%CI 1.29 至 2.44）；p<0.000）和州（1.62（95%CI 1.19 至 2.22）；p=0.003）政府的 COVID-19 信息的信任是两次调查中口罩使用的预测因素。
悉尼和墨尔本在 2020 年 7 月和 9 月都报告了较高水平的口罩佩戴率，这与维多利亚州的第二波疫情和口罩强制令以及当时悉尼的集群爆发相符。高口罩使用率可能是由于对国家和州政府、口罩强制令、风险认知、当前疫情以及当时 COVID-19 感染风险的认知水平的高信任度所解释。
