摘要

背景:疫苗犹豫不决是一项复杂的挑战,需要采取全面的方法,不仅要承认社区内的合理担忧,还要积极应对错误信息。在此背景下,本研究旨在调查巴西人相信 COVID-19 疫苗阴谋论的普遍程度,并试图了解与这种行为相关的因素。研究方法我们利用 2020 年 5 月至 8 月间进行的一项全国性在线调查,对 4247 名参与者进行了抽样调查,并进行了多变量分析,以确定这种坚持的独立决定因素,计算出调整后的流行率 (APR) 及其 95% 置信区间。结果显示结果显示,27.7% 的参与者至少相信一种阴谋论。与较高的信奉程度相关的因素包括:同意社交媒体上至少一条 COVID-19 的错误信息(APR:3.65;95% CI:3.07-4.34)、在大流行期间参加休闲活动没有困难(APR:3.11;95% CI:1.85-5.24)、年龄在 50 岁或以上(APR:1.70;95% CI:1.49-1.94)、在大流行期间参加防护活动没有困难(APR:3.11;95% CI:1.85-5.24)、年龄在 50 岁或以上(APR:1.70;95% CI:1.49-1.94)。APR:1.70;95% CI:1.49-1.94)、获得保护措施没有困难(APR:1.47;95% CI:1.26-1.72)、使用口罩(APR:1.62;95% CI:1.33-1.97)、不使用至少一种传统媒体信息来源(APR:1.47;95% CI:1.26-1.72)、女性(APR:1.41;95% CI:1.25-1.60)和年龄在 30-49 岁之间(APR:1.35;95% CI:1.19-1.52)。结论我们的研究结果突出表明,必须认识到疫苗接种犹豫并不仅仅是一种孤立的现象,其根源往往在于社会、文化、心理和政治因素的复杂相互作用。有必要采取多方面的策略来消除疫苗迟疑,有效解决阴谋论问题,并考虑与疫苗迟疑普遍存在有关的各种因素。

Belief in Conspiracy Theories about COVID-19 Vaccines among Brazilians: A National Cross-Sectional Study
Background: Vaccine hesitancy is a complex challenge that demands a comprehensive approach, one that not only acknowledges legitimate concerns within communities but also actively confronts misinformation. In this context, this study aimed to investigate the prevalence of belief in conspiracy theories about COVID-19 vaccines among Brazilians, seeking to understand the factors associated with this behavior. Method: Utilizing a national online survey conducted between May and August 2020, with a sample of 4247 participants, we conducted multivariate analysis to identify the independent determinants of this adherence, calculating adjusted prevalence ratios (APRs) and their 95% confidence intervals. Results: It was revealed that 27.7% of participants believed in at least one conspiracy theory. Factors associated with a higher level of adherence included agreement with at least one piece of COVID-19 misinformation on social media (APR: 3.65; 95% CI: 3.07–4.34), lack of difficulty accessing leisure activities during the pandemic (APR: 3.11; 95% CI: 1.85–5.24), age 50 years or older (APR: 1.70; 95% CI: 1.49–1.94), absence of difficulty accessing protective measures (APR: 1.47; 95% CI: 1.26–1.72), use of face masks (APR: 1.62; 95% CI: 1.33–1.97), non-use of at least one traditional media source for information (APR: 1.47; 95% CI: 1.26–1.72), female gender (APR: 1.41; 95% CI: 1.25–1.60), and age between 30 and 49 years (APR: 1.35; 95% CI: 1.19–1.52). Conclusions: Our findings highlight that it is crucial to recognize that vaccine hesitancy is not merely an isolated phenomenon but often rooted in a complex interplay of social, cultural, psychological, and political factors. There is a need for multifaceted strategies to combat vaccine hesitancy, effectively address conspiracy theories, and consider the various factors associated with their prevalence.
