Mask wearing mitigates the spread of COVID-19; however, many individuals have not adopted the protective behavior.
We examine mask wearing behavior during the height of the pandemic in Los Angeles County, and its association with COVID-19 testing and willingness to get vaccinated.
We conducted a cross-sectional survey using representative sampling between December 2020 and January 2021, through an online platform targeting Los Angeles County residents. Survey items include demographic characteristics, health conditions, access to health care, mask wearing, COVID-19 testing, exposure risk factors, and willingness to receive COVID-19 vaccine. We performed logistic regression models to examine factors associated with always mask wearing.
Of the analytic sample (n = 1,984), 75.3% reported always wearing a face mask when leaving home. Being a female, Asian or African American, or non-Republican resident, or having higher education, having poor or fair health, having a regular doctor, knowing someone hospitalized for COVID-19, and being willing to receive the COVID-19 vaccine were associated with always wearing a mask. Residents who were younger, had a highest risk health condition, and had ≥2 COVID-19 tests had lower odds of always mask wearing.
Mask wearing guidelines are easing; however, as vaccination rates plateau and new virus variants emerge, mask wearing remains an important tool to protect vulnerable populations. Encouraging protective measures among younger adults, those with less education, republicans, men, and White residents-groups that are least likely to be vaccinated or wear a mask-may be critical to reducing transmission.
佩戴口罩可以减轻 COVID-19 的传播；然而，许多人并没有采取这种保护行为。
我们在洛杉矶县 COVID-19 疫情高峰期调查口罩佩戴行为，及其与 COVID-19 检测和接种疫苗意愿的关系。
我们于 2020 年 12 月至 2021 年 1 月期间通过一个针对洛杉矶县居民的在线平台，采用代表性抽样进行了横断面调查。调查项目包括人口统计学特征、健康状况、获得医疗保健的机会、口罩佩戴、COVID-19 检测、暴露风险因素和接种 COVID-19 疫苗的意愿。我们进行了逻辑回归模型分析，以研究与始终佩戴口罩相关的因素。
在分析样本（n=1984）中，75.3%的人表示离家时始终佩戴口罩。女性、亚裔或非裔美国人或非共和党居民、受教育程度较高、健康状况较差或一般、有固定医生、认识因 COVID-19 住院的人、愿意接种 COVID-19 疫苗与始终佩戴口罩相关。年龄较小、患有最高危健康状况、接受过≥2 次 COVID-19 检测的居民佩戴口罩的可能性较低。
口罩佩戴指南正在放宽；然而，随着疫苗接种率趋于平稳和新病毒变异株的出现，佩戴口罩仍然是保护弱势群体的重要工具。鼓励年轻成年人、受教育程度较低的人、共和党人、男性和白人居民（最不可能接种疫苗或佩戴口罩的人群）采取保护措施，对于减少传播可能至关重要。
