In the evaluation of dietary intake of populations, one is often interested in the habitual (usual) intake, i.e. the long-term average intake. For example to estimate the proportion of a population that meets nutritional recommendations. In food consumption surveys, dietary intake is generally collected with short-term measurements, 24-hr recalls or food records. The dietary intake of an individual can vary considerably from day to day. Consequently, intake measured over a limited number of days will be a poor indicator of the individual as well as population’s habitual intake. Statistical modelling makes it possible to estimate the population's habitual intake distribution from repeated short-term measurements. In this course the focus will be on statistical modelling of habitual intake using SPADE (Statistical Program to Assess Dietary Exposure).
PhD candidates, postdocs, or other researchers interested in this course should work on statistical analyses of food consumption data and have a basic understanding of applied statistics. Since SPADE is an R Package, basic knowledge of R and RStudio is necessary. A dedicated, basic e-learning course on R and R-Studio specifically focused to use SPADE is provided in advance. Participants are expected to follow this e-learning before starting the course.
Participants will learn
1) the principles of habitual intake modelling for populations
2) the use of SPADE for habitual intake modelling of foods, food groups, energy and nutrients.
The course is a 2 days hands-on course with a maximum of 25 participants (PhD’s, postdocs, other researchers). The course will consist of a combination of lectures on general principles of modelling habitual intake, lectures on how to use SPADE, and practical exercises with SPADE.
We will teach you hands on experience in using SPADE. SPADE is implemented in a freely available, open-source software R for statistical computing. See for more information
