The primary outcome was frailty assessed using the revised Japanese Cardiovascular Health Study criteria. In this cross\u2010sectional study, the independent variable was computer and smartphone use for health information acquisition and health management. The mediating variable was health literacy measured using the Communicative and Critical Health Literacy Scale. Mediation analysis was conducted, adjusting for age, gender, educational attainment, and household income, with 95% confidence intervals (CIs) estimated via bootstrapping.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Results<\/jats:title>\n                    <jats:p>\n                      Of 451 participants, 423 were analyzed.
