Introduction to Public Health Epidemiology and Research Design

Understanding how diseases spread and how to prevent them is the cornerstone of global health. This text-based course introduces you to the core principles of epidemiology, helping you make sense of complex health data and research. You will develop the critical thinking skills needed to design sound epidemiological studies and critique existing health literature. By mastering foundational concepts, you will learn to identify risk factors, evaluate public health interventions, and understand modern disease surveillance systems. What you'll learn: - Understand the fundamental principles, key terminology, and history of public health epidemiology. - Design and evaluate common observational and experimental study designs, including cohort and case-control studies. - Calculate and interpret key health metrics, such as incidence, prevalence, relative risk, and odds ratios. - Critique published epidemiological research to identify potential biases, confounding variables, and limitations. - Explore modern digital epidemiology techniques and contemporary public health surveillance systems. The course begins with core definitions and historical context before guiding you through study design, statistical measures, and critical evaluation techniques. You will read real-world scenarios and practice analyzing population health data through written exercises. This course is designed for beginners, aspiring public health professionals, and healthcare workers with no prior background in epidemiology. Start your journey into public health research and learn to analyze the health patterns of populations.
