Course Epidemiology I - Basic Principles of Epidemiology

The course C155/29 Epidemiology I - Basic Principles of Epidemiology is being offered by the Graduate School of Health, Aarhus University, 2023.

Criteria for participation: University degree in medicine, dentistry, nursing, or master’s degree in other fields and/or postgraduate research fellows (PhD students and research-year medical students).

Aim: To teach basic epidemiologic study designs, measures of occurrence and association and interpretation and inference. Please see teaching objectives for details.

Learning outcomes: By the end of the course the student should be able to:

• Define epidemiologic measures of occurrence and explain the difference between prevalence and incidence.
• Define the following epidemiologic measures of association; relative risk, risk ratio, odds ratio, and rate ratio, risk difference and excess risk, including attributable risk and population attributable risk.
• Define and describe strengths, weaknesses, and main applications of the designs; ecological, cross-sectional, follow up, case-control and intervention studies.
• Define selection bias, information bias and confounding and be aware that evaluating the direction and strength of a possible bias or confounding is essential.
• Learn to think along the lines that, when faced with data from an analytic epidemiologic study showing an association (or no association), this might reflect; random error, bias (systematic error), including selection bias or information bias, or confounding, or, if all other possibilities seem unlikely, causality.

Workload: The full workload of the course is expected to be 44 hours.

Content: Epidemiologic measures of occurrence and association, study designs - including macro-epidemiological, cross-sectional, case-control and cohort studies as well as experimental, randomized controlled trials - interpretation and inference, including random error, selection, and information bias, confounding and effect modification. A specific session will deal with causation. Please see time schedule and teaching objectives for details.

It is recommended that students read an introductory epidemiology text prior to the course. For example one of the texts below:

• Svend Juul. Epidemiologi og evidens. Munksgaard Danmark, 3rd edition, 2017. ISBN13: 9788762816398
• Neil Pearce. A Short Introduction to Epidemiology, 2nd Edition, February 2005. ISBN 0-476-01236-8. (available at e.g. https://courses.cit.cornell.edu/bionb4280/Intro_Epidemiology.pdf)

Instructors: Bodil Hammer Bech and Ulrik Schiøler Kesmodel

Venue: Aarhus University, Aarhus

Participation in the course is without cost for:
