Background and study aims People often chose the food they eat according to how healthy it is, how much it costs and convenience. However, it is not really known to what extent an older persons socioeconomic background (for example their wealth, education and/or occupation) affects their food choices. A discrete choice experiment (DCE) - a method of finding out peoples preferences and their reasons for such preferences - is one way to find out why people choose the food that they do. Here, we want to investigate differences in food motives between socioeconomic groups by means of a DCE. Who can participate? Healthy adults. What does the study involve? A DCE is carried out during a face-to-face interview among older adults as part of the GLOBE cohort study taking part in the Netherlands. Participants are offered a series of choice sets about a usual dinner at home, and are asked, for each choice set, to select one of two meals or neither if they prefer. Each meal has a different combination of five meal attribute levels. That is, each meal varies according to how healthy it is, its taste, preparation time, travel time to shop to buy ingredients and the price. The results are then analysed. What are the possible benefits and risks of participating? There are no risks of taking part in the trial. Each participant receives a gift voucher of 10 euro after participation. Where is the study run from? Erasmus MC: University Medical Center Rotterdam (Netherlands) When is the study starting and how long is it expected to run for? March 2012 to March 2014 Who is funding the study? Department of Public Health, Erasmus MC, Rotterdam (Netherlands) Who is the main contact? Dr Carlijn Kamphuis [email protected]
