Wearing a facemask can help to decrease the transmission of COVID-19. We investigated self-reported mask use among subjects aged 18 years and older participating in the COVID-19 Community Research Partnership (CRP), a prospective longitudinal COVID-19 surveillance study in the mid-Atlantic and southeastern United States. We included those participants who completed ≥5 daily surveys each month from December 1, 2020 through August 31, 2021. Mask use was defined as self-reported use of a face mask or face covering on every interaction with others outside the household within a distance of less than 6 feet. Participants were considered vaccinated if they reported receiving ≥1 COVID-19 vaccine dose. Participants (n = 17,522) were 91% non-Hispanic White, 68% female, median age 57 years, 26% healthcare workers, with 95% self-reported receiving ≥1 COVID-19 vaccine dose through August 2021; mean daily survey response was 85%. Mask use was higher among vaccinated than unvaccinated participants across the study period, regardless of the month of the first dose. Mask use remained relatively stable from December 2020 through April (range 71-80% unvaccinated; 86-93% vaccinated) and declined in both groups beginning in mid-May 2021 to 34% and 42% respectively in June 2021; mask use increased again since July 2021. Mask use by all was lower during weekends and on Christmas and Easter, regardless of vaccination status. Independent predictors of higher mask use were vaccination, age ≥65 years, female sex, racial or ethnic minority group, and healthcare worker occupation, whereas a history of self-reported prior COVID-19 illness was associated with lower use.
佩戴口罩有助于减少新冠病毒的传播。我们调查了参与新冠病毒社区研究伙伴关系（CRP）的18岁及以上受试者自我报告的口罩使用情况，CRP是美国中大西洋和东南部地区一项前瞻性纵向新冠病毒监测研究。我们纳入了那些在2020年12月1日至2021年8月31日期间每月完成≥5次每日调查的参与者。口罩使用被定义为自我报告在与家庭以外距离小于6英尺的其他人每次互动时使用口罩或面部遮盖物。如果参与者报告接种了≥1剂新冠病毒疫苗，则被视为已接种疫苗。参与者（n = 17522）中91%为非西班牙裔白人，68%为女性，年龄中位数为57岁，26%为医护人员，截至2021年8月，95%的人自我报告接种了≥1剂新冠病毒疫苗；每日调查平均回复率为85%。在整个研究期间，无论首剂接种月份如何，接种疫苗的参与者的口罩使用率均高于未接种疫苗的参与者。从2020年12月到4月，口罩使用率相对稳定（未接种疫苗者为71%-80%；接种疫苗者为86%-93%），从2021年5月中旬开始，两组的口罩使用率均下降，2021年6月分别降至34%和42%；自2021年7月以来，口罩使用率再次上升。无论疫苗接种状况如何，在周末以及圣诞节和复活节期间，所有人的口罩使用率都较低。较高口罩使用率的独立预测因素包括接种疫苗、年龄≥65岁、女性、种族或族裔少数群体以及医护人员职业，而自我报告的既往新冠病毒感染病史与较低的口罩使用率相关。
