COVID-19 has resulted in over 1 million deaths in the U.S. as of June 2022, with continued surges after vaccine availability. Information on related attitudes and behaviors are needed to inform public health strategies. We aimed to estimate the prevalence of COVID-19, risk factors of infection, and related attitudes and behaviors in a racially, ethnically, and socioeconomically diverse urban population.
The DFW COVID-19 Prevalence Study Protocol 1 was conducted from July 2020 to March 2021 on a randomly selected sample of adults aged 18-89 years, living in Dallas or Tarrant Counties, Texas. Participants were asked to complete a 15-minute questionnaire and COVID-19 PCR and antibody testing. COVID-19 prevalence estimates were calculated with survey-weighted data.
Of 2969 adults who completed the questionnaire (7.4% weighted response), 1772 (53.9% weighted) completed COVID-19 testing. Overall, 11.5% of adults had evidence of COVID-19 infection, with a higher prevalence among Hispanic and non-Hispanic Black persons, essential workers, those in low-income neighborhoods, and those with lower education attainment compared to their counterparts. We observed differences in attitudes and behaviors by race and ethnicity, with non-Hispanic White persons being less likely to believe in the importance of mask wearing, and racial and ethnic minorities more likely to attend social gatherings.
Over 10% of an urban population was infected with COVID-19 early during the pandemic. Differences in attitudes and behaviors likely contribute to sociodemographic disparities in COVID-19 prevalence.
截至 2022 年 6 月，COVID-19 已导致美国超过 100 万人死亡，疫苗供应后仍持续激增。为了制定公共卫生策略，我们需要了解与 COVID-19 相关的态度和行为。我们旨在评估在一个种族、民族和社会经济多样化的城市人群中 COVID-19 的流行率、感染的危险因素以及相关的态度和行为。
DFW COVID-19 患病率研究方案 1 于 2020 年 7 月至 2021 年 3 月期间在德克萨斯州达拉斯或塔兰特县随机选择的 18-89 岁成年人样本中进行。要求参与者完成一个 15 分钟的问卷和 COVID-19 PCR 和抗体检测。使用经过调查加权的数据计算 COVID-19 的流行率估计值。
在完成问卷的 2969 名成年人中（加权应答率为 7.4%），有 1772 名（加权率为 53.9%）完成了 COVID-19 检测。总体而言，有 11.5%的成年人有 COVID-19 感染的证据，其中西班牙裔和非西班牙裔黑人、基本工人、居住在低收入社区和教育程度较低的成年人的感染率高于其同龄人。我们观察到态度和行为因种族和民族而异，与非西班牙裔白人相比，他们不太相信戴口罩的重要性，而种族和民族少数群体更有可能参加社交聚会。
在大流行早期，城市人口中有超过 10%的人感染了 COVID-19。态度和行为的差异可能导致 COVID-19 流行率的社会人口统计学差异。
