Infodemic and sources of information about COVID-19 in a Brazilian population: what are the associated factors?

Abstract

Background: With the COVID-19 pandemic, social isolation, and information search have increased dramatically. This increased search for information about the Coronavirus, called infodemic, was greatly affected by fake news and information without scientific evidence. This article aimed to assess the infodemic amid the COVID-19 pandemic and its association with sociodemographic and pandemic-related variables, as well as describe the main sources from which people obtained information about COVID-19.

Methods: A cross-sectional population-based study was performed in Criciúma, Brazil. All individuals aged 18 years or older, residing in the 607 households systematically selected, were invited to answer the questionnaire. Infodemic and sources to seek information about COVID-19 were evaluated, as well as sociodemographic and pandemic-related variables. Adjusted Poisson regression with robust variance was used to evaluate associations.

Results: A total of 863 individuals participated in the study. The prevalence of infodemic was 22.1%, and television was the main source of information (58.9%). Three groups presented a higher prevalence of infodemic: older adults (PR: 1.65), individuals with low income (PR: 2.97), and those who had had contact with someone infected (PR: 2.20).

Conclusions: The findings reflect how some groups are more exposed to infodemic, and underline the responsibility and importance of intersectoral actions for dissemination of information about COVID-19.
