The coronavirus disease 2019 (COVID-19) pandemic has disproportionately affected Asian American communities, highlighting the need to understand the factors that influence vaccination rates, especially within subpopulations. Many trust studies have found that healthcare institutions, peers, and nonmedical health drivers play key roles in shaping vaccination decisions within specific subgroups, underscoring the need to examine these factors among subpopulations like Vietnamese Americans to develop targeted interventions. Unfortunately, Vietnamese Americans, a significant population in Texas, have limited disaggregated data available, a knowledge gap this study seeks to fill.
The National Institutes of Health (NIH) Community Engagement Alliance (CEAL) Common Survey 2 instrument was used online and via paper in English and Vietnamese. Trained volunteers, outreach events, and local Texas clinics recruited adults of Vietnamese heritage from December 2022 to April 2023. The data were analyzed through multivariable logistic regression.
Of the 425 participants who responded to a survey, the responses of 278 who completed all pertinent questions were included in the analysis. Respondents demonstrated high trust in healthcare providers (AOR [adjusted odds ratio] 2.97, 95% CI: 1.28-6.86; p = 0.011) and in the federal government (AOR 3.02, 95% CI: 1.32-6.88; p = 0.009) for COVID-19 information were associated with increased odds of COVID-19 vaccination. In contrast, high trust in peers at work or school for COVID-19 information (AOR 0.51, 95% CI: 0.22-0.89; p = 0.041) and a pandemic-related challenge of having clean water to drink in the past month (AOR 0.30, 95% CI: 0.13-0.71; p = 0.006) were associated with decreased odds of COVID-19 vaccination.
Trust in healthcare providers and the federal government was associated with increased COVID-19 vaccine receipt among Vietnamese Americans, whereas trust in peers and endorsing COVID-19 challenges decreased COVID-19 vaccine receipt. Understanding the facilitators and barriers to vaccination among Vietnamese Americans can improve COVID-19 health equity and outcomes.
2019年冠状病毒病（COVID-19）大流行对亚裔美国人社区造成了尤为严重的影响，凸显了了解影响疫苗接种率的因素的必要性，特别是在亚人群体中。许多信任研究发现，医疗机构、同龄人以及非医疗健康驱动因素在特定亚组的疫苗接种决策中起着关键作用，这突出了在越南裔美国人等亚人群体中研究这些因素以制定针对性干预措施的必要性。不幸的是，作为德克萨斯州的一个重要群体，越南裔美国人可用的分类数据有限，本研究旨在填补这一知识空白。
美国国立卫生研究院（NIH）社区参与联盟（CEAL）通用调查问卷2通过在线和纸质形式以英语和越南语进行。从2022年12月至2023年4月，经过培训的志愿者、外展活动以及德克萨斯州当地诊所招募了具有越南血统的成年人。数据通过多变量逻辑回归进行分析。
在425名回复调查问卷的参与者中，对278名完成所有相关问题的参与者的回复进行了分析。受访者对医疗服务提供者（调整后的优势比[AOR]为2.97，95%置信区间：1.28 - 6.86；p = 0.011）和联邦政府（AOR为3.02，95%置信区间：1.32 - 6.88；p = 0.009）在COVID-19信息方面表现出高度信任，这与COVID-19疫苗接种几率增加相关。相比之下，对工作或学校中的同龄人在COVID-19信息方面的高度信任（AOR为0.51，95%置信区间：0.22 - 0.89；p = 0.041）以及过去一个月中与大流行相关的饮用水清洁挑战（AOR为0.30，95%置信区间：0.13 - 0.71；p = 0.006）与COVID-19疫苗接种几率降低相关。
对医疗服务提供者和联邦政府的信任与越南裔美国人中COVID-19疫苗接种率的提高相关，而对同龄人的信任以及认可COVID-19挑战则降低了COVID-19疫苗接种率。了解越南裔美国人接种疫苗的促进因素和障碍可以改善COVID-19健康公平性和结果。
