Health literacy and COVID-19 pandemic impacts among adults in rural northern Arizona.

Introduction: Limited health literacy - the ability to access, process, and use health information and services - contributes to persistent health inequities. Yet little is known about associations of limited health literacy with impacts from the COVID-19 pandemic, particularly for US adults in rural areas. This study sought to determine associations of limited health literacy with impacts from the COVID-19 pandemic among a diverse sample of adults in rural Northern Arizona.

Methods: A cross-sectional, interviewer-administered survey was conducted with 119 adults from June 2020 to August 2021. Participants were recruited from two federally qualified health centers and by word of mouth. The Newest Vital Sign was used to measure health literacy, and the Epidemic-Pandemic Impacts Inventory was used to measure the effects of the COVID-19 pandemic on various aspects of personal and family life (eg spent more time on screens and devices, had family celebrations canceled or restricted). Descriptive, bivariate, and multivariable linear regression statistics were computed.

Results: Nineteen percent of participants had limited health literacy, and participants had an average of 22 individual impacts and 2 household impacts of the 92 COVID-19 impacts assessed. Multivariable regression model results showed that being male versus female or having public only versus any private insurance was significantly associated with fewer individual COVID-19 impacts on average. Being black, Indigenous, people of color versus White or being Hispanic, Latino, or Spanish versus not were each associated with significantly more individual COVID-19 impacts on average. Limited versus adequate health literacy was significantly associated with more household COVID-19 impacts on average. Sensitivity analysis results further showed that limited versus adequate health literacy was associated with significantly higher adjusted rates of household social, emotional, and infection COVID-19 impacts.

Conclusion: This study's findings highlight the importance of assessing and accounting for health literacy in clinical practice and health services research addressing the impacts of the COVID-19 pandemic and future emergency events.
