The appropriate use of facemasks, recommended or mandated by authorities, is critical to prevent the spread of COVID-19 in the community. We aim to evaluate frequency and quality of facemask use in general populations.
A multi-site observational study was carried out from June to July 2020 in the west of France. An observer was positioned at a predetermined place, facing a landmark, and all individual passing between the observer and the landmark were included. The observer collected information on facemask use (type, quality of positioning), location and demographic characteristics.
A total of 3354 observations were recorded. A facemask was worn by 56.4% (n = 1892) of individuals, including surgical facemasks (56.8%, n = 1075) and cloth masks (43.2%, n = 817). The facemask was correctly positioned in 75.2% (n = 1422) of cases. The factors independently associated with wearing a facemask were being indoors (adjusted odds ratio [aOR], 2.7; 95% confidence interval [CI] 2.28-3.19), being in a mandatory area (aOR, 6.92; 95% CI 5-9.7), female gender (aOR, 1.75; 95% CI 1.54-2.04), age 41-65 years (aOR, 1.7; 95% CI 1.43-2.02) and age > 65 years (aOR, 2.28; 95% CI 1.83-2.85). The factors independently associated with correct mask position were rural location (aOR, 1.38; 95% CI 1.07-1.79), being in an indoor area (aOR, 1.85; 95% CI 1.49-2.3), use of clothmask (aOR, 1.53; 95% CI 1.23-1.91), and age > 40 years (aOR, 1.75 95%CI 1.37-2.23).
During the initial phase of the COVID-19 pandemic, the frequency and quality of facemask wearing remained low in the community setting. Young people in general, and men in particular, represent the priority targets for information campaigns. Simplifying the rules to require universal mandatory facemasking seemed to be the best approach for health authorities.
当局推荐或强制使用口罩对于防止社区内 COVID-19 的传播至关重要。我们旨在评估一般人群中口罩使用的频率和质量。
本多地点观察性研究于 2020 年 6 月至 7 月在法国西部进行。一名观察者位于预定地点，面向地标，所有从观察者和地标之间经过的个体均被纳入研究。观察者收集口罩使用（类型、位置质量）、地点和人口统计学特征的信息。
共记录了 3354 次观察。56.4%（n=1892）的个体佩戴了口罩，包括外科口罩（56.8%，n=1075）和布口罩（43.2%，n=817）。口罩正确佩戴的比例为 75.2%（n=1422）。与佩戴口罩相关的独立因素包括在室内（调整后的优势比[OR]，2.7；95%置信区间[CI]2.28-3.19）、在强制区域（OR，6.92；95%CI 5-9.7）、女性（OR，1.75；95%CI 1.54-2.04）、41-65 岁（OR，1.7；95%CI 1.43-2.02）和年龄>65 岁（OR，2.28；95%CI 1.83-2.85）。与口罩正确位置相关的独立因素包括农村地区（OR，1.38；95%CI 1.07-1.79）、在室内区域（OR，1.85；95%CI 1.49-2.3）、使用布口罩（OR，1.53；95%CI 1.23-1.91）和年龄>40 岁（OR，1.75 95%CI 1.37-2.23）。
在 COVID-19 大流行的初始阶段，社区环境中口罩的佩戴频率和质量仍然很低。年轻人，尤其是男性，是信息宣传的重点目标人群。简化要求普遍强制佩戴口罩的规则似乎是卫生当局的最佳方法。
