Learning Objectives: 1. Review epidemiologic study designs to answer your hypothesis. 2. Focus on observational studies rather than clinical studies. 3. Describe ecologic, cross-sectional, cohort and case-control epidemiologic study designs. More Information: https://www.cctst.org/ctronline

Learning Objectives: 1. Define descriptive epidemiology and its advantages. 2. Describe advantages and disadvantages. 3. Review specific examples of descriptive epidemiology by age, sex and location. More information: https://www.cctst.org/ctronline

Learning Objectives: 1. Describe analytic epidemiology, or studies that allow assessment of hypotheses of associations of suspected risk factor exposures with health outcomes. 2. Discuss observational epidemiology, or ecologic study design using populations/groups of individuals as units of study. 3. Introduce observational epidemiology, or study design using individuals as units of study (e.g. cross-sectional, cohort/prospective, and case-control studies - focus of following videos of Dr. Patrick Ryan Lectures: Parts 4, 5 & 6).

Learning Objectives: 1. Examine the relationship between health outcome and some variable of interest (i.e. exposure) as they exist in a defined population at a given point in time. 2. Describe the usefulness of a cross-sectional study to assess prevalence of disease and its major drawback. 3. Discuss the advantages and disadvantages of a cross-sectional study design.

Learning Objectives: 1. Identify cohort study design, measuring a group (cohort) of healthy people and following them over time. 2. Discuss occurrence of health-related events measured and compare the occurrence across exposure categories. 3. Describe advantages and disadvantages of cohort study design.

Learning Objectives: 1. Compare cases (individuals with health outcome of interest in your study) and controls (individuals free of health outcome) with respect to an exposure or risk factor. 2. Describe assumptions that must be considered when designing and conducting case-control studies. 3. Discuss the advantages and disadvantages of case-control study design.
