Anbefalte forkunnskaper

Basic knowledge in quantitative research methods and successful completion of the following courses: EX-605 Philosophy of Science in Health and Sport Sciences and ME-626 General Quantitative Research Methods.

Innhold

The course outlines the general principles of epidemiology as a core science of public health. The course addresses the fundamental epidemiologic concepts encompassing the different types of research designs. The course also highlights the critical aspects of using epidemiologic research to describe the occurrence of diseases at population level as well as to identify the causes of diseases and to assess the efficacy of treatment and preventive regimens.

1. Introduction to the principles and foundations of epidemiology

• Pioneers in epidemiology and history of causal thinking in public health
• Basic epidemiologic concepts concerning the definitions of population, types of research, hypothesis, association, causal link, types of variables, exposure, outcome, bias and confounder
• Epidemiologic thinking and the rationale of moving from population data observation into developing and testing epidemiologic hypothesis

2. Measures of disease frequency and measures of association

• Measures of incidence and prevalence and the related types of events
• Measures of effect, association and impact between exposures and outcomes

3. Causal relationships

• Theoretical causal mechanisms involving sufficient cause and component cause model
• Causal criteria proposed by Hill: understanding their strengths and limits

4. Types of epidemiologic studies

• Observational studies: cross-sectional, ecological, case-control studies and cohort studies
• Intervention trials: quasi-experimental trials, randomized clinical trials, community intervention trials

5. Validity

• Evaluation of bias and strategies to mitigate bias in epidemiologic studies
• Assessment of confounding and approaches to handle confounders
• Identification and interpretation of interaction (effect modification)

6. Epidemiology in clinical settings

• Studies of diagnostic and screening tests
