Digital health technologies are increasingly used for chronic disease management, but their effectiveness depends on patients’ digital health literacy. This cross-sectional study assessed the relationship between digital health literacy and self-management behaviors among 1,200 adults with diabetes, hypertension, or cardiovascular disease. Data were collected via surveys evaluating access to health apps, understanding of digital resources, and adherence to treatment plans. Results revealed that participants with higher digital literacy demonstrated significantly better adherence to medications, lifestyle modifications, and monitoring routines (p < 0.01). Barriers included limited internet access, lack of technical skills, and low health literacy. The study underscores the importance of digital literacy training and tailored interventions to optimize chronic disease self-management.
