Epidemiology Beyond the Basics: Chapter 1 | Part 5

In this video, we provide a comprehensive breakdown of core epidemiological study designs and analytical concepts. We begin with cross-sectional studies, examining how they measure exposure and outcome simultaneously, before exploring the complexities of analyzing trends through age, cohort, and period effects. Next, we cover ecologic studies and the unique challenges of population-level data. From there, we transition into individual-level methodologies, contrasting standard cohort studies with case-control designs. Finally, we dive into advanced hybrid structures, comparing nested case-control and case-cohort studies, and conclude with a look at how matching is used to control for confounding variables.
