在covid-19大流行期间，几乎所有人(99%)都戴口罩，其中大多数人(73.3%)表现出良好的口罩使用依从性。然而，41.8%的参与者在戴口罩前很少洗手，超过一半(55.3%，62.1%)的参与者在戴口罩时触摸(n=8108, 79.8%)或调整(n=9356, 92.0%)戴口罩后没有持续洗手。当取下使用过的口罩时，7.6%的参与者将口罩扔进没有盖子的垃圾桶，22.5%的参与者将口罩扔进自己伸手可及的垃圾桶，不管是否有盖子。受访者报告佩戴一次性医用口罩(93.8%)，其次是N95口罩(26.2%)和布口罩(8.5%)。一些参与者同时戴着多个口罩(偶尔是26.5%，通常是2.1%，总是1.5%)。共有5981人(58.8%)表示会重复使用一次性口罩，其中近三分之二(n=3923, 65.6%)表示会将使用过的口罩挂在通风良好的地方。超过三分之一(37.6%)的受访者在使用口罩超过8小时后没有更换口罩。接触口罩使用说明是依从性最强的预测因子(优势比=4.13,95%CI= 3.60-4.75,p=0.000)。其他因素还包括特定的环境、地点和性别。年龄的影响需要进一步的调查。大多数受访者(76.4%)主要通过社交媒体平台获取信息。
Universal face mask use was recommended owing to the growing pandemic of the coronavirus disease (COVID-19). However, little is known about the public's compliance with mask-wearing behaviours.
To evaluate the public's mask-wearing behaviours in the context of COVID-19.
Online survey from 6 April 2020 to 5 May 2020 in China.
This study included 10,165 persons who lived in China, understood Chinese, and were not health care providers.
Descriptive statistics were used to assess the public's mask-wearing behaviours. A binary logistic regression analysis was performed to identify the risk factors affecting the mask-wearing behaviours.
Nearly all (99%) people wore a mask during the covid-19 pandemic, with most (73.3%) demonstrating good compliance with face mask use. However, 41.8% of the participants seldom cleaned their hands before putting on a face mask, and more than half (55.3%, 62.1%) of those who touched (n=8108, 79.8%) or adjusted (n=9356, 92.0%) their mask while using it failed to consistently wash their hands afterward. When removing a used mask, 7.6% of the participants discarded it into a garbage bin without a lid and 22.5% discarded it into a garbage bin in their reach regardless of presence of a lid. Participants reported wearing disposable medical masks (93.8%), followed by N95 respirators (26.2%), and cloth face masks (8.5%). Some participants wore multiple masks simultaneously (occasionally 26.5%, often 2.1%, always 1.5%). A total of 5,981 (58.8%) participants reported reusing disposable masks, with nearly two thirds (n=3923, 65.6%) indicating they would hang the used masks in well-ventilated places. More than one-third (37.6%) of the respondents did not replace mask when it had been used for more than 8 hours. Exposure to instructions on face mask use was the strongest predictor of good compliance (odds ratio=4.13, 95% confidential interval= 3.60-4.75, p=0.000). Other factors included specific situations, location, and gender. The influence of age needs further investigation. Most participants (76.4%) accessed information mainly via social media platforms.
Nearly all people wore face mask and most of them used it properly during the COVID-19 pandemic. Hand hygiene before and during mask-wearing, choosing an appropriate type of face mask, reusing disposal face mask, and disposing of used face masks should be particularly emphasized in future evidence dissemination or behaviour-change interventions. Information on social media platforms for evidence dissemination and behaviour change may benefit the public the most, but this initiative requires further research to investigate its effectiveness.
