Abstract

Preventive medicine and public health play a pivotal role in reducing the global burden of disease, improving life expectancy, and lowering healthcare costs. This paper explores the intersection of modern technology, evidence-based policies, and behavioral interventions in advancing preventive healthcare. Key focus areas include the application of artificial intelligence (AI) and big data in predictive analytics, the impact of genomics on personalized prevention, and the role of digital health tools such as wearables and telemedicine. Additionally, the paper examines public health strategies, including vaccination programs, lifestyle interventions, and environmental health policies, while addressing challenges such as economic barriers, health disparities, and ethical concerns. Finally, future directions are discussed, emphasizing AI-driven public health surveillance, precision medicine advancements, and global collaborative efforts. By integrating technological innovation with robust public health frameworks, preventive medicine can transform healthcare delivery and promote long-term population health.
