Health Disparities in Online COVID-19 Information Seeking and Protective Behaviors: A Two-Wave Longitudinal Study.

The COVID-19 outbreak was declared a pandemic by the World Health Organization and claimed hundreds of thousands of lives in the U.S. However, the adoption of protective behaviors in response to COVID-19 varies among sociodemographic groups. To better understand the disparities in U.S. adults' adoption of protective behaviors in relation to sociodemographic factors, we conducted a two-wave panel survey in the U.S. Although sociodemographic factors were not found to be significant predictors in lagged regression analysis, results from a cross-sectional analysis showed that the White, younger, and higher educated individuals were more likely to take protective behaviors. Furthermore, based on the structural equation modeling, indirect effects were observed. Specifically, online COVID-19 information seeking mediated the effects of age and education on performance of protective behaviors, and subjective norms and online COVID-19 information seeking were found to be significant serial mediators of these relationships. The study not only extends the health disparities and health information seeking literature, but also offers practical insights to health campaigns and interventions promoting protective behaviors during a pandemic and reducing health disparities.
