The association between the type of offline social participation and digital literacy among Korean older adults: a cross-sectional study

Abstract Background Poor social connections are associated with poor digital literacy. Poor digital literacy could induce poor outcomes in daily life or health status, especially among older adults. This study aimed to investigate the effect of social participation based on its absolute magnitude on digital literacy and to confirm the well-known fact that social participations are good for digital literacy is applicable regardless of activity types in a sample of older Korean adults. Methods A total of 9,297 adults aged 65 years or older from the 2020 National Survey of Older Koreans were analyzed. All data were self-reported. Poor digital literacy was defined by limited usage of digital devices. Offline social participation was evaluated using seven different social activities: senior community activities, learning activities, religious activities, volunteer work, leisure, political groups, and club activities. Multivariable logistic regression analysis with covariate adjustment was used for the analysis. Results Engaging in more than two types of social participation was associated with higher digital literacy: adjusted odds ratio (aOR) 1.965, 95% confidence interval (CI) 1.567–2.465 for two types of participation, and aOR 2.558, 95% CI 2.040–3.208 for more than three types of participation. Additionally, social participation occurring less than once a month and most types of offline activities were associated with improved digital literacy. However, senior community activities were negatively associated with digital literacy (aOR 0.762; 95% CI 0.681–0.852). Conclusions In this sample of older Korean adults, it was found that the lower the social participation, the poorer the digital literacy. This association may induce the isolation of older adults from societies especially for older adults with senior community activities.
