Understanding Disease, Health Inequalities, and Promotion Strategies

This presentation provides an overview of key concepts in public health, including the definitions of disease and ill health, and the principles behind health inequalities. It explores strategies for health promotion, the role of epidemiology and demographics in public health, and various theories and approaches used in health promotion. The presentation covers the differences between illness and disease, classifications of disease, and the importance of health promotion in reducing premature deaths and costs. It further discusses the effectiveness of health promotion, its five key approaches (medical, behavioral change, educational, client-centered, and societal change), and the role of epidemiology in prevention and control. The presentation also highlights the role of the National Health Service and uses examples like Dr. John Snow's cholera investigation to illustrate epidemiological studies. Finally, it examines health promotion models and the health belief model, alongside approaches like lifestyle changes and behavioral changes for improved health outcomes. The presentation emphasizes the effectiveness of health promotion techniques and tools in supporting population health.
