초록/요약

The purpose of this study was to compare the mean scores of e-health literacy, health information, social relationships, and psychological status between younger, middle-aged, and older Korean adults during the COVID-19 pandemic and to identify the factors associated with e-health literacy as well as the moderating effect of age on the association between health information factors and e-health literacy. We used a cross-sectional survey of 2400 Korean adults aged 20 years or older residing in Seoul. Descriptive statistics, ANOVA, chi-square test, and hierarchical multiple regression analyses were used to analyze the data. Findings demonstrated an age-group difference in the mean score of e-health literacy with the older group having lower e-health literacy than the other groups. Health information, social support, and COVID-19-related anxiety were associated with e-health literacy and a moderating effect of age on the association between sources of health information and e-health literacy was also identified among the three age subgroups. This study emphasizes the importance of identifying e-health-related risk factors leading to health disparities between age groups. © 2023 The Author(s).
