One of the main objectives of nutrition research is to provide scientific evidence for the role of diet in human health and disease. High quality dietary assessment methods and biomarkers are crucial to optimally design studies in this field. Nutrition research is often blamed for poor exposure assessment that might impair its usefulness. Therefore, studies that evaluate the validity of dietary assessment methods are important to allow proper inference from such studies. Consequently, researchers should master the concepts and principles underlying evaluation studies.
The course is meant for university graduates in biomedical sciences; nutrition, epidemiology etc. Knowledge on basic statistical concepts and methods (e.g. linear regression, paired t-test, correlation, ANOVA) and study designs is assumed. The course welcomes PhD candidates and postdocs as well as participants from industry and research centres.
- The course will address methodological aspects of exposure assessment in nutrition and related fields of biomedical research. After participation the participant:
- is able to make a well-informed choice from different methods of exposure assessment;
- has insight in sources of measurement errors, consequences for exposure asssessment, impact on associations observed, and methods to account for these errors;
- is able to design and analyse evaluation studies, and t quantitatively present and interpret their results;
- is able to critically evaluate exposure assessment in nutrition and related fields of biomedical research.
The course consists of a series of lectures, supported by computer-assisted exercises. Also, discussions on exposure assessment in the participant’s own research will be part of the programme. The following topics will be addressed:
- State-of-the-art and recent developments in dietary assessment for different research questions and study designs, including issues relevant to collection of biomarkers in practice.
- Study designs for evaluation studies assessing validity and reproducibility, focusing on level of intake, nature of variation in diet, ability of ranking subjects, followed by the application of results in calibration of exposure and diattenuation of associations.
- Error models in exposure assessment, addressing systematic and random errors (group level bias, intake related bias, person-specific bias, day-to-day-variation, instrumental bias).
- Statistical methodology to estimate usual intake and uncertainty in dietary assessment.

Registration & course fee
The number of participants to the course is limited to 30. We encourage all our participants to come to the beautiful Wageningen Campus for this in person and interactive training. However for those who are not able to travel to Wageningen due to COVID-19 restrictions, this course can be offered online (hybrid course). We only have a max. of 4 online places available and cannot guarantee an online spot for every participant, so in case we exceed the 4 online participants, the Graduate School VLAG will decide which participants can join online.
