Nutritional Epidemiology; Diet; Food Consumption Surveys; Social Disparities

Abstract : This research project is the prerequisite step to a major intervention trial aimed at reducing social inequalities regarding diet in adolescents and young adults. Social and cultural disparities in this period of life have indeed been little analysed so far despite the availability of food consumption data in various countries, especially regarding effect of migration status on diet. Within the present doctorate, the objective will be to study social (age, gender, family composition, education...) and cultural (language and migration status) disparities in diet of the adolescents and young adults in Belgium. Existing repeated databases will be used to compare, in social and cultural groups, diet described by various dimensions (dietary and nutrient intake, scores of diet quality, use of industrial, catering or home-made meals...) and changes over time. First, the National Food Consumption Surveys will help comprehensively study diet in adolescents and young adults using 24-hour recalls; this survey has been carried out in 2004 and 2014. Secondly, we will use the Health Behaviour in School-aged Children cycles in 11, 13 and 15 years students. Carried out every four years since 1983, the last survey has been carried out in 2013-2014 in Belgium. Scientific publications are planned along with communication to the general public of the main results. In the meantime, a group of research will be built to define lines of interventions to consider in these age groups.
