Projects

Development and validation of dietary assessment methods

Overall objective: to develop up to date, accurate and efficient dietary assessment methods

Today several methods have been developed and evaluated (24-h recall interview module, Food frequency Questionnaires, precoded food diary with a picture booklet and different biological markers), however this is a continuous process where new technology also are incorporated. The group invests ressources in reducing potential errors in the applid methods, and in using biological markers as comparison standards when possible.

KostReg (Norwegian Diet Registry)

Overall objective: Development of a unique infrastructure and a platform that will allow extensive low-cost diet registration in large epidemiological studies.

Continuously updated information of dietary intake is essential for following and understanding the rapid changes occurring in Norwegian subpopulations. It is also essential for understanding the causal factors driving the health development in Norway.

The Department of Nutrition has initiated an unprecedented project that aims to include such information about body weight, diet, physical activity and other lifestyle factors from the majority of the Norwegian population above the age of 15. The project is in collaboration USIT (the IT department at the University of Oslo), and the first step will be to development a platform based on a web-based system with informed consent, food frequency questionnaires, and electronic communications tools and benchmarking.

National dietary surveys

Overall objectives: to identify potential nutritional challenges in the food intake and meal pattern among different age groups in the Norwegian population which may call for a public health action

In collaboration with the Directorate for Health and the Food Safety Authorities we conduct national dietary surveys in representative samples of infants(Spedkost), toddlers (SmĂĄbarnskost), preschoolers (Ungkost), schoolchildren (Ungkost), adolescents (Ungkost) and adults (Norkost). Subprojects are enlarged food composition database and development of software systems.

The role of school and home environments in predicting healthy weight development of Norwegian adolescents

Overall objectives: add to the limited knowledge about how school and home environment influence weight development, dietary and physical activity behaviour of schoolchildren/adolescents in a longitudinal perspective.

A longitudinal study; schoolchildren are followed from the age 11-12 y until two years later. A new follow-up when the scoolchildren were 15 y was finished this year. This is the control arm of the HEIA intervention project and is called the HEIA-cohort.
