Research and Practice of Preventive Medicine

Preventive medicine, as a key pillar of the modern medical system, is committed to preventing the occurrence, development, and spread of diseases through scientific means, thereby ensuring the health and safety of the population. This study systematically reviewed the core content of preventive medicine in terms of basic theories, epidemiological foundations, health education, and health promotion. Research suggests that preventive medicine encompasses primary, secondary, and tertiary prevention strategies aimed at eliminating pathogenic factors at the source, early detection and treatment of diseases, and promoting patient recovery and health management. Epidemiology, as an important cornerstone of preventive medicine, provides scientific basis for developing precise prevention measures through descriptive, analytical, and experimental research. Especially in the prevention and control of infectious diseases and chronic disease management, epidemiological investigation and analysis play a crucial role. In addition, health education and health promotion, as key components of preventive medicine, effectively enhance the health awareness and self-care ability of the population through educational activities and health policies, promote the formation of healthy behaviors, and reduce the incidence of diseases.
