Introduction to Preventive and Social Medicine (PSM)

Effective public health requires understanding how diseases spread and how communities function. Preventive and Social Medicine (PSM), also known as Community Medicine, provides the essential framework for this knowledge. This course provides a structured, text-based introduction to the core domains of PSM, including biostatistics, environmental health, demography, and health administration. You will build a solid conceptual foundation necessary for tackling advanced studies or professional challenges in public health and clinical medicine. What you'll learn: * Understand the fundamental principles of epidemiology, including measures of disease frequency and study designs (e.g., cohort, case-control). * Master core biostatistical concepts necessary for interpreting medical literature, such as probability, sampling, and basic hypothesis testing. * Analyze the determinants of health and disease, focusing on social, environmental, and behavioral factors affecting population well-being. * Apply knowledge of public health administration to understand the structure and functioning of primary healthcare systems and national health programs. * Learn the ethical guidelines and practical challenges associated with conducting community health surveys and research studies. The course begins with definitions and the scope of PSM, moving systematically through epidemiology and biostatistics, before covering environmental health, nutrition, and the organization of health services. We use clear explanations and practical examples throughout the text. This course is designed for absolute beginners, including medical students, public health enthusiasts, and anyone seeking a comprehensive introduction to community medicine. No prior knowledge of medicine or statistics is required. Start building your expertise in vital public health concepts today.
