Assumed knowledge on:

Before your start this course, be sure you are able to:
- describe the characteristics of major study designs (i.e., cohort study, case-control study, cross-sectional study);
- understand and calculate effect measures (e.g., IP, IR, IPR, IRR, OR);
- explain the concepts causality, validity, external validity, internal validity, selection bias, information bias, confounding, effect measure modification, stratification, precision, and bias;
- analyse an association between an exposure and a continuous outcome;
- interpret regression coefficients from linear regression;
- perform basic statistics in R by writing R script (in R studio);
The above-mentioned learning outcomes are related to the courses “MAT-15303 Statistics 1” plus “MAT-15403 Statistics 2” or “MAT-14303 Basic Statistics”, “MAT-24306 Advanced Statistics for Nutritionists”, “HNH-24806 Introduction to Epidemiology and Public Health”, “HNH-31006 Study Design and Interpretation in Epidemiology and Public Health”.

Continuation courses:

- HNH-31606 Analytical Epidemiology II – Causal thinking and analysis;
- Thesis Nutrition and Disease;
- Thesis Global Nutrition.

Contents:

In this course, you will focus on data analysis and interpretation of the results of cross-sectional studies, case control studies and longitudinal studies in humans for studying diet-disease associations.
The focus is on adjustment of confounding and identification of effect measure modification.

This course can not be combined in an individual study programme together with HNH-37306 Applied data analysis or HNH-30806 Analytical Epidemiology, when in doubt, contact your study adviser. This course can not be combined in an individual programme with HNH-33403 Advanced Analytical Epidemiology (online) and/or HNH-35903 Integration of evidence II (online).

Learning outcomes:

After successful completion of this course students are expected to be able to:
- execute and interpret descriptive statistics as a way to explore a dataset prior to studying diet-disease associations;
- explain stratified analysis, linear regression analysis, logistic regression analysis, survival analysis and longitudinal data analysis while handling confounding and effect measure modification in studying diet-disease associations;
- perform stratified analysis, linear regression analysis, logistic regression analysis, survival analysis and longitudinal data analysis while handling confounding and effect measure modification and interpret the data - following from these analysis in studying diet-disease associations;
- perform methods to adjust for energy, including the multivariate, density, and residual approach in a statistical program and interpret the coefficients of each of the three energy adjustment approaches;
- organize and document data analysis systematically for studying diet-disease associations while using the statistical program R;
- design a protocol for data analysis by identifying potential confounding variables and effect measure modifying variables based on literature and review a data analysis plan of others;
- explain the difference between the epidemiological and statistical approach while studying confounding and effect measure modifiers.

Activities:

- Self-study;

- E-modules and exercises on the computer;
- Group work;
- Lectures.

Examination:

The final mark of this course is determined on the basis of the results of a theoretical exam (60%), a practical exam (40%) and a group assignment (pass/fail)

The minimum mark for theoretical examination and practical examination 5.5 for each. The group assignment must be passed..
