Proactive Health defines “proactive health” as the continuous process of maintaining and enhancing physical, mental, and social well-being through anticipatory actions, data-informed self-management, and enabling environments. The journal bridges biomedical discovery, digital innovation, behavioral science, population health, and policy, welcoming contributions that illuminate the determinants, technologies, interventions, and implementation strategies that enable people and societies to stay healthy, detect risks earlier, and slow or prevent the onset of disease.
