On April 3, 2020, the White House Coronavirus Task Force and CDC announced a new behavioral recommendation to help slow the spread of coronavirus disease 2019 (COVID-19) by encouraging the use of a cloth face covering when out in public (1). Widespread use of cloth face coverings has not been studied among the U.S. population, and therefore, little is known about encouraging the public to adopt this behavior. Immediately following the recommendation, an Internet survey sampled 503 adults during April 7-9 to assess their use of cloth face coverings and the behavioral and sociodemographic factors that might influence adherence to this recommendation. The same survey was administered 1 month later, during May 11-13, to another sample of 502 adults to assess changes in the prevalence estimates of use of cloth face coverings from April to May. Within days of the release of the first national recommendation for use of cloth face coverings, a majority of persons who reported leaving their home in the previous week reported using a cloth face covering (61.9%). Prevalence of use increased to 76.4% 1 month later, primarily associated with increases in use among non-Hispanic white persons (54.3% to 75.1%), persons aged ≥65 years (36.6% to 79.2%), and persons residing in the Midwest (43.7% to 73.8%). High rates were observed in April and by May, increased further among non-Hispanic black persons (74.4% to 82.3%), Hispanic or Latino persons (77.3% to 76.2%), non-Hispanic persons of other race (70.8% to 77.3%), persons aged 18-29 years (70.1% to 74.9%) and 30-39 years (73.9% to 84.4%), and persons residing in the Northeast (76.9% to 87.0%). The use of a cloth face covering was associated with theory-derived constructs that indicate a favorable attitude toward them, intention to use them, ability to use them, social support for using them, and beliefs that they offered protection for self, others, and the community. Research is needed to understand possible barriers to using cloth face coverings and ways to promote their consistent and correct use among those who have yet to adopt this behavior.
2020 年 4 月 3 日，白宫冠状病毒特别工作组和疾病预防控制中心宣布了一项新的行为建议，鼓励在公众场合使用布面覆盖物，以帮助减缓 2019 年冠状病毒病（COVID-19）的传播（1）。在美国人口中，尚未对广泛使用布面覆盖物进行研究，因此，对于鼓励公众采用这种行为知之甚少。建议发布后不久，在 4 月 7 日至 9 日期间，一项针对 503 名成年人的互联网调查评估了他们对布面覆盖物的使用情况，以及可能影响他们遵守这一建议的行为和社会人口因素。同样的调查在一个月后，即 5 月 11 日至 13 日，对另外 502 名成年人进行了评估，以评估从 4 月到 5 月布面覆盖物使用的流行率估计值的变化。在发布第一个全国范围内使用布面覆盖物的建议后的几天内，报告上周离开家的人中，大多数人报告使用了布面覆盖物（61.9%）。一个月后，使用率上升至 76.4%，主要与非西班牙裔白人（54.3%至 75.1%）、65 岁及以上人群（36.6%至 79.2%）和居住在中西部地区的人群（43.7%至 73.8%）的使用率增加有关。4 月份和 5 月份的高使用率，在非西班牙裔黑人（74.4%至 82.3%）、西班牙裔或拉丁裔（77.3%至 76.2%）、非西班牙裔其他种族（70.8%至 77.3%）、18-29 岁（70.1%至 74.9%）和 30-39 岁（73.9%至 84.4%）以及居住在东北部地区（76.9%至 87.0%）的人群中观察到了更高的使用率。使用布面覆盖物与表明对其有利的态度、使用意图、使用能力、使用支持以及相信它们为自己、他人和社区提供保护的理论衍生结构有关。需要研究了解使用布面覆盖物可能存在的障碍，以及如何促进那些尚未采用这种行为的人正确、持续地使用布面覆盖物。
