Differences in attitude toward COVID-19 based on internet and social media usage among community-dwelling older adults during the first state of emergency

Abstract

Aim: In order to understand the digital divide among older adults during the coronavirus disease 2019 (COVID-19) pandemic, we investigated the association between internet use and compliance with COVID-19 preventive behaviors during the first state of emergency in Japan. Methods: A total of 8952 community-dwelling citizens aged 75 years and above were asked about their preventive behaviors during the first state of emergency using a paper-based questionnaire. Among them, 51% responded and were divided into internet users and non-users. We used multivariable logistic regression models to estimate the adjusted odds ratios and 95% confidence intervals of internet use for compliance with preventive behaviors. Results: Approximately 40% of the respondents used the internet, and 9.29% used social media to collect COVID-19-related information. Internet usage was independently associated with compliance with using hand sanitizers, avoiding going out, avoiding eating out, avoiding traveling, getting vaccinated, and getting tested for COVID-19; the adjusted odds ratios (95% confidence intervals) were 1.21 (1.05–1.38), 1.19 (1.04–1.37), 1.20 (1.05–1.38), 1.32 (1.15–1.52), 1.30 (1.11–1.53), and 1.23 (1.07–1.41), respectively. Exploratory subgroup analyses demonstrated that social media users might have shown early adaptation to newly recommended preventive behaviors during the first state of emergency. Conclusions: Results suggest that a digital divide exists, as evidenced by the varied compliance with preventive behaviors depending on internet use. Additionally, social media use may be associated with early adaptation to newly recommended preventive behaviors. Therefore, future studies regarding the digital divide among older adults should investigate differences depending on the types and content of internet resources.
