Objectives

Purpose of this work package (WP4) is to evaluate the assessment of diet and the measurement properties and applicability of new technologies to assess diet in large-scale studies.

Description of the work

Diet can be defined in terms of foods and nutrients and is characterized by dietary methods ranging from simple questions to Food Frequency Questionnaires to more detailed diet methods such as 24-hour recalls and 7- day diet diaries. As these methods differ in the information obtained and their applicability for different population groups and purposes (public health monitoring, surveillance, epidemiology) a review will be carried out of the available methods. The first step would be to collect data on all dietary methods already used in large-scale European population studies. Examples of information to be collected would be the type and purpose of the dietary method, the socio-cultural characteristics of the population and response rates. Literature searches on known methods and to identify innovative, new methods not generally used so far on a large scale in Europe (e.g. checklists, computerized 24-hour recall) would be made. As the errors incurred with current methods are not independent of each other, priority will be given to studies incorporating biological markers as objective indices of intake. A score will be developed to evaluate the reliability, validity and appropriateness of the different dietary methods for different socio-cultural groups and purposes e.g. for epidemiology, surveillance or public health monitoring.

Furthermore, in datasets of the partners forming prospective populations with different socio-cultural backgrounds and recent dietary assessment, specific analysis will be performed that report on the feasibility of dietary assessment in terms of participation rates, work load to the study participants and acceptability of methods.

Internal and external experts in the field will also be consulted in a workshop. SWOT-analysis (Strength, Weakness, Opportunities, Threats) will be performed on the new dietary assessment technologies (http://www.mindtools.com/pages/article/newTMC_05.htm). Also projects such as PIPS aiming at collecting personalized information will be contacted. Particular emphasis will be given to their suitability for use in different socio-cultural settings and to evaluate their use in monitoring and driving public health behaviours.

The findings from this exercise will be summarized in a report.
