Aims:In today’s technology-driven world, the general public increasingly relies on wearable devices and online platforms to monitor their health and access health-related information. This study explored how online health knowledge-seeking behavior and the use of wearable devices influence health decision-making behavior, with digital health literacy serving as a mediating factor. Instrument & Methods:This correlational cross-sectional study collected 1,196 valid responses from the general public in Guntur city who actively use wearable devices and online platforms to seek health-related knowledge. Data analysis was carried out using Smart PLS, employing partial least squares structural equation modeling for path analysis and bootstrapping with 5,000 samples to assess mediation effects. Findings:All structural model paths were statistically significant (p<0.05). Online health knowledge-seeking behavior and wearable device usage positively influenced health decision-making behavior both directly (β=0.296; β=0.254) and indirectly through digital health literacy (β=0.397; β=0.421). Digital health literacy had the strongest effect on decision-making behavior (β=0.431). Mediation analysis confirmed partial mediation, as direct effects remained significant alongside indirect effects. Conclusion:Digital health literacy plays a central role in translating access to technology and online information into informed health decisions.
